A Multi-method Exploration of Resilience. 3 Abstract The role of factors which influenced individual differences in post-trauma outcome were explored using a multi-method design, in response to recommendations in the literature that self-report data should be incorporated into studies of post-traumatic stress disorder (PTSD). In part 1, a psychophysiological study with process interviews was tested for feasibility and acceptability with a small-scale sample (n = 17) and found individual differences between how participants described responding to trauma-related picture stimuli. Five primary response types were identified: avoidance, acceptance, increased attendance, dismissal and confrontation. In part 2, resilient and recovered individuals (n = 11) were interviewed in depth about their experiences of coping with trauma and transcripts were analysed using an interpretative phenomenological approach. Themes identified were attitudes and beliefs, emotion regulation, narrative development, support and safety and recovery. Some resilient participants described initial use of avoidance as a coping strategy but moved from this position towards acceptance of their trauma in their recovery journey. Therefore avoidance may play a more helpful role than has previously been thought. The importance of specific attributes of factors positively associated with recovery from trauma and potential interactions between these factors was discussed. Keywords: Post-traumatic stress disorder, resilience, coping, trauma, emotion regulation. TRAUMA AND RESILIENCE 4 Literature Overview Post-traumatic stress disorder (PTSD) can develop in response to exposure to severely traumatic events, such as threatened or actual death or serious injury, or threat to the physical integrity of the self or others, which inspire feelings of helplessness, fear or horror (American Psychological Association, 2000). It is a highly disabling condition (Elsesser, Sartory & Tackenburg, 2005), affecting functioning across domains and producing symptoms of intrusive recollections, avoidance and numbing, and hyperarousal (APA, 2000). Many trauma exposed individuals do not go on to develop PTSD, even following extreme stressors such as incarceration in the Holocaust concentration camps (Barel, Sagi-Schwartz, Van Ijzendoorn & Bakermans-Kranenburg, 2010) and war trauma or torture (Johnson & Thompsen, 2008). Latent growth mixed modelling statistical techniques have identified several post-trauma trajectories of symptomatology and functioning: chronic PTSD, delayed onset PTSD, PTSD followed by recovery, and resilience (Bonnano, 2004). The resilient pathway, in which people showed some initial symptoms before quickly resuming baseline functioning, was the most common response to trauma (Bonnano, Westphal & Mancini, 2011; Norris, Tracy & Galea, 2009). Researchers have examined the variables that distinguish resilient individuals, or those who successfully recover, from those who develop chronic PTSD (Elwood, Hahn, Olatunji & Williams, 2009). A range of significant individual vulnerabilities and social and demographic variables have been identified, but these have failed to explain more than a low proportion of the variance (Elwood et al., 2009). Psychophysiological research has been a useful methodology to explore some variables because findings have provided an opportunity to reconsider the pathophysiology of PTSD (Pole, 2007). In his meta-analysis of 122 psychophysiological studies, Pole (2007) concluded that the ability to regulate the TRAUMA AND RESILIENCE body following trauma exposure, measured through skin conductance habituation to startle sounds, 5 rather than the initial startle response researchers had previously concentrated on, had the most robust effect size and therefore was the most promising variable in potentially discriminating resilient and PTSD individuals. However, Pole (2007) suggested the variance within these findings might reflect a sub-group of PTSD participants utilising numbing or dissociation strategies when confronted with the trauma-related stimuli. Therefore participants may have used different emotion regulation strategies, an area requiring further research. The importance of emotion regulation was supported by Mancini and Bonnano’s (2006) two year follow-up of survivors of the 9/11 terrorist attacks, where the strongest predictor of resilience was flexibility on emotion regulation, measured as the ability to engage in emotional expression or suppression when instructed to do so. These researchers argued that given the complexity of the phenomenon of resilience, psychological studies must examine actual outcomes after a potentially traumatic event, and not simply focus on characteristics globally associated with resilience. These findings support emotion dys-regulation models of PTSD (e.g., Lanius, Frewen, Vermetten & Yehuda, 2010), which explain PTSD development as a failure to manage unwanted emotional experiences following stress sensitization, resulting in individuals alternating between overand under-modulation. This model therefore accounts for both the hyper-arousal and hypo-arousal symptoms of PTSD, a challenge which has eluded some alternative theories. It would therefore be useful to explore the differences between trauma exposed individuals with and without current PTSD in terms of emotional regulation when exposed to trauma-related stimuli. Schaubroeck, Peng, Riolli & Spain (2011) have called for a study of how people respond during the TRAUMA AND RESILIENCE 6 period they are exposed to trauma related stimuli and both Pole (2007) and Bonnano et al. (2011) have suggested that self-report data should be examined alongside psychophysiological measures, filling a gap in the existing literature. The phenomenological psychopathology approach, in which self-report data are combined with neurological or physiological data to better understand an experience, has recently gained popularity in neuroimaging research (e.g., Lutz & Thompsen, 2003) and would be appropriate. This proposed design would be novel and might therefore be tested in a small-scale feasibility and acceptability study to identify whether different data could be usefully combined in order to enhance understanding of individual differences in psychophysiological reaction to trauma-related stimuli. However, a comprehensive understanding of resilience to trauma would need to consider how the individual responded to their trauma experience, as well as how they behave in the laboratory when presented with a traumatic stressor (Pole, 2007; Mancini & Bonnano, 2006). Given the heterogeneity of the trauma resilient population and the wide variety of potential factors associated with resilience including personality, interpersonal and stressor variables (see, for example, Elwood et al, 2009), qualitative methods which enable a detailed, idiographic description of the experience would give a more comprehensive insight than self-report measures based on a specific concept or theory driven qualitative methodologies. Interpretative phenomenological analysis (IPA; Smith, 2004), a qualitative research approach that examines how people make sense of their major life experiences (Smith, Flowers & Larkin, 2009) has been employed in recent studies with topics related to PTSD and resilience, such as the experience of being a family member of a veteran with PTSD (Ray & Vanstone, 2009), exploration of young offenders’ responses to traumatic experiences (Paton, Crouch & Camic, 2009) and examination of the TRAUMA AND RESILIENCE experiences of people living in risky and disadvantaged circumstances (Stanley, 2011). Given the 7 focus on developing a better understanding of the experience of an individual who has undergone a major life event, IPA would be an appropriate method for the exploration of the coping strategies and recovery process undergone by participants after their real-life trauma. Aims and Research Questions Review of the literature has concluded that psychological study of variables associated with resilience, of which emotional regulation appears promising, should include self-report data corresponding to the psychophysiological symptom under investigation, as well as exploration of actual resilience after a potentially traumatic event. The aim of this research project is test both of these recommendations: firstly, by conducting a feasibility study to examine whether combining psychophysiological and self-report data is a useful and acceptable design when applied to this research topic; and secondly, by using a phenomenological qualitative method to explore how recovered or resilient individuals responded to actual traumatic events. 1. To ascertain whether the combination of psychophysiological data (heart rate response) and selfreport data (process interviews) in a phenomenological psychopathology design is feasible and acceptable as a novel methodology to address the research question of whether trauma survivors with PTSD show slower heart rate habituation to trauma-related stimuli in comparison to survivors without PTSD. 2. To explore through self-report data how the participants responded to or coped with the traumarelated picture stimuli. 3. To explore how trauma-resilient individuals experienced and responded to their trauma experiences through interpretative phenomenological analysis of semi-structured interviews. TRAUMA AND RESILIENCE Method 1: Psychophysiological Feasibility Study 8 Design This feasibility and acceptability study combined cross-sectional psychophysiological data with process interviews. Pre-study Power Calculation Pole’s (2007) meta-analytic review did not report an effect size for heart rate habituation slope (HRHS) to trauma cues due to a lack of existing studies. However, his meta-analysis reported medium effect sizes, with significant heterogeneity, for heart rate reaction to both standardized and idiographic trauma cues. Therefore assuming as a starting point a potential medium effect size for HRHS (r = 0.5), this study design which predicted the direction of the difference between means for two independent groups would need to recruit 51 participants per group to achieve acceptable statistical power (0.8). Participants Figure 1 outlines the participant recruitment process. All applicants met the following inclusion criteria: aged 18 years or over; direct experience or witnessing at least one traumatic event in their lifetime which fulfilled criterion A for PTSD diagnosis (DSM-IV-R; APA, 2000); and ability to attend the study site in the South West of England within the four moth testing window. None met the exclusion criteria which comprised currently taking prescribed cardiac medication, having a pacemaker fitted, having a history of cardiac surgery that would influence heart rate response, or currently taking prescribed psychotropic medication for any mental health condition which might influence heart rate (e.g. medications for anxiety or depressive conditions). TRAUMA AND RESILIENCE 9 31 individuals expressed an interest in participating in the study in response to community advertising and were sent the participant information sheet (see Appendix 5). 21 individuals booked an appointment to take part in the study. 17 individuals took part in the psychophysiological study. 10 individuals did not proceed further with the study despite follow-up email contact. 4 individuals were unable to attend or reschedule their appointments due to ongoing illness and new work commitments. Figure 1. Flowchart Outlining Recruitment Process. The participant group comprised seven men and ten women and were aged between 20 and 70 years (mean = 44 years). The vast majority described themselves as White British (88%) with the remaining two participants reporting White European (n=1) or Chinese (n=1) ethnicity. Six reported formal psychiatric diagnoses, primarily depression (n=6), PTSD (n=4), anxiety (n=4), mental fatigue (n=1) and agoraphobia (n=1). Measures Life events checklist (Blake, Weathers, Nagy et al., 1995). This screening measure lists 16 potentially traumatic events known to result in PTSD or other post-traumatic difficulties (Gray et al., 2004) and an item inquiring about inordinately stressful events not captured by the other items. It has adequate reliability and stability as a screening measure of direct trauma experience and strong convergence with measures of psychopathology associated with trauma exposure (Gray et al., 2004). TRAUMA AND RESILIENCE 10 Participants completed a 5-point scale to indicate their level of exposure to the trauma and were scored two points for each event that had happened to them and one point for each event that they had witnessed. PTSD checklist – civilian version (PCL-C; Weathers, Litz, Huska & Keane, 1994). This 17-item self-report instrument parallels diagnostic criteria B, C and D for PTSD, as specified in the DSM-IV (APA, 1994). The PCL-C has been found to have strong internal consistency and good testretest reliability, as well as convergent and discriminant validity (Ruggiero, Del Ben, Scotti & Rabalai, 2003). For each PTSD symptom the participant indicated on a 5-point Likert scale the extent to which they have been bothered by that problem in the last month. Participants were scored between one and five points for each response with higher scores indicating greater symptomatology and were scored against the diagnostic criteria to identify the presence of PTSD or sub-threshold PTSD (APA, 2000).

Multiple event types within an event category (e.g. physical and sexual assault) were not included. Process interview for psychophysiological testing. The semi-structured process interview guide was developed by the researcher and reviewed by a clinical psychologist with significant psychophysiological and trauma-related research and clinical experience. The process interview took approximately five minutes to administer and was designed to capture the experience and recollections of the participant immediately following their viewing of the picture stimuli (see Appendix 6). Stimulus Material and Paradigm Forty-eight full-screen coloured pictures were presented sequentially, each presented for 6000ms with a 3000ms white screen gap in between each picture, using Eprime software. The 48 pictures comprised 12 pictures in each of 4 categories: trauma related, neutral, pleasant and unpleasant. The category order was randomised and within each category picture order was randomised. Pictures TRAUMA AND RESILIENCE 12 were taken predominantly from the International Affective Picture System (IAPS; Lang, Bradley & Cuthbert, 1995). Different versions of the experiment were prepared with various trauma types (natural disaster, fire, military conflict, car accident, interpersonal violence) to allow for matching between stimuli and participant trauma experience. Psychophysiological Data Collection Heart rate (HR) was determined from continuously recorded electrocardiogram (ECG) using AcqKnowledge software, version, 4.1.1. ECG was measured using electrodes placed below the participant’s right collar bone and on their left side underneath the ribcage. The ECG signal was sampled at 1000 Hz with a low pass filter of 35 Hz and a high pass filter of 0.5 Hz. For HR determination the data were transformed using a template correlation to remove large artefacts, and R peaks were identified on the ECG waves. Remaining artefacts from noisy, missing or ectopic beats were interpolated from the adjacent R-peaks (this was only necessary in one case). The interpolation procedure was used for less than 5% of the ECG data. HR in beats per minute (bpm) were then extracted stimulus-locked over a -1 to 6 s time window. Procedures Ethical approval was obtained from the Plymouth and Cornwall NHS Research Ethics Committee and the University of Exeter’s School of Psychology Ethics Committee (see Appendices 2 and 3). Participants gave written informed consent and were not paid for taking part although travel expenses were reimbursed and a small prize draw was carried out. Participants were recruited through community advertising and purposive sampling. Participants contacted the researcher by email or telephone and were sent information about the study and the consent form (see Appendices 4 and 5). Those who consented completed a screening form and the psychometric battery either at home themselves or at an appointment with the researcher. TRAUMA AND RESILIENCE 13 The psychophysiological experiment took place at a university laboratory. Participants were seated approximately 60 cm from a computer screen and asked to find a comfortable position and sit as still as possible for the duration of the experiment, which lasted approximately 8 minutes. Participants were instructed to simply observe the picture material and advised that they would be asked some questions about what they thought of the pictures afterwards. The researcher left the room and dimmed the lights to enhance picture observation. Following presentation completion the researcher re-entered the room, ended the ECG recording and began the process interview. Process interviews took place as soon as possible after the participant had viewed the final picture and removed their ECG recording devices. The researcher used the semi-structured process interview schedule, omitting any questions that the participant spontaneously discussed and exploring further any points raised by the participant. These interviews were digitally recorded. Participants who also took part in study two were offered a short break and refreshments at this stage before starting their study two procedure whilst other participants were debriefed to ensure they were not in any way distressed before leaving. Analysis Strategy Psychophysiological data. Heart rate analysis was performed using Acqknowledge software, version 4.1.1 to assist with data cleaning and extraction. The mean and standard deviation of beats per minute were extracted for the 1000ms prior to each picture presentation in order to establish a baseline for each participant. Mean, standard deviation, maximum and time of maximum beats per minute were then extracted for each 1000ms interval from 0 to 6000ms following picture presentation so that a response wave could be calculated for the entire 6000ms presentation per picture. Category and picture order for each participant were extracted from Eprime software. This data was transported into Excel 2010 and SPSS version 20 for analysis. TRAUMA AND RESILIENCE First baseline HR response was taken from the participant’s HR in the 1000ms window 14 immediately prior to the first trauma-related picture presentation. Mean HR response was calculated by deducting the mean baseline HR response from the mean HR response to each trauma-related picture presentation for each 1000ms interval of the presentation window. Maximum HR response was calculated by deducting the mean baseline HR response from the maximum HR response recorded over the 6000ms presentation per picture. Process interviews. Each digitally recorded process interview was transcribed by the researcher. The analysis involved identification of any cognitive or physical coping strategies that participants used in response to thoughts, feelings or physical reactions to the trauma pictures they had seen. These reactions and coping strategy responses were coded and a list of strategies produced. Each transcript was then checked against the code list to ensure that all relevant data had been captured and that the list accurately reflected the responses given. The responses and strategies for each participant were summarised (see Appendix 8). Results 1: Psychophysiological Feasibility Study Research Question 1. To ascertain whether the combination of psychophysiological data (heart rate response) and self-report data (process interviews) in a phenomenological psychopathology design is feasible and acceptable as a novel methodology to address the research question of whether trauma survivors with PTSD show slower heart rate habituation to trauma-related stimuli in comparison to survivors without PTSD. TRAUMA AND RESILIENCE Feasibility 15 This study required recruitment of 102 participants in total to achieve an acceptable level of statistical power based on the assumption of a medium effect size. Over the six month recruitment period 31 individuals contacted the researcher to express an interest in the study but only 17 went on to take part. Of these participants six met criteria for current PTSD symptomatology and eleven did not present with PTSD. This would suggest that both groups were difficult to recruit with the PTSD group especially problematic. Therefore future efforts to achieve full power with this design might require recruitment from a wider geographical area (either multi-site design or use of portable laboratory equipment), a longer recruitment period, an enhanced budget in order to provide a more meaningful incentive for participation and a review of the advertising literature in order to encourage applications from individuals with PTSD. Acceptability None of the participants expressed regret or distress at having taken part in the study. One participant with PTSD brought her mother with her for support. Another individual reported that viewing the trauma-related pictures, in this case car crashes, had reminded him of his own accident and that this memory in turn had reminded him of other traumatic events that he had experienced (witnessing the murder of a friend as a child). He commented that whilst he had not thought about this event in a long time, he was not upset to have done so. None of the participants required further support following the study or contacted the researcher with any concerns Therefore this study design appeared to have been acceptable to participants, however the researcher provided generous time allocation per participant (at least 1.5 hours) in order to allow settling in time, progress through the procedures at the individual’s own pace and plenty of time for debrief and unhurried conversation at the end. This level of time investment may need to be maintained in order to also maintain acceptability. TRAUMA AND RESILIENCE 16 Group Differences in HRHS Response to Trauma-Related Pictures The small sample size recruited prevented statistical analyses being carried out on the data set.

TRAUMA AND RESILIENCE Research Question 2. 18 To explore through self-report data how the participants responded to or coped with the traumarelated picture stimuli. Process interviews. Participants reported a variety of cognitive, physical and emotional reactions to the picture stimuli. With reference to the trauma related stimuli, some participants described no reaction (n=4). Others described predominantly mild feelings of tension (n=7), concern (n=3), curiosity (n=3), sadness (n=3), anger (n=2), dislike (n=1) and feeling threatened (n=1). Just over half of the sample (59%) described a physical response to the images of increased bodily tension. Cognitive and physiological strategies were employed by some participants in response to the trauma related stimuli. These are described in Table 4. Table 4 Coping Strategies Employed in Response to Trauma-related Picture Stimuli Strategy Description Example from transcript N Focussing attention elsewhere or “probably the peripheral stuff, like the girl 5 on peripheral details within the watching rather than the accident itself. I image. noticed she was wearing a red coat” [P12]. Accepting and tolerating “Just let it impact on me rather than attempt discomfort provoked by the to respond”. [P10]. employed Avoidance Acceptance 5 image. Increased Engaging with and thinking about “for some strange reason it was more the attention the people or events in the image. violent ones I was paying attention to and 4 TRAUMA AND RESILIENCE 19 imagining the scene”. [P8]. Reduced Dismissing the image as “they were relatively run of the mill and no attention uninteresting or unremarkable. different from anything I’ve seen in twenty 2 odd years”. [P7]. Confrontation Forcing oneself to look at the image. “there were a couple which I didn’t want to 1 look at but…I made myself keep looking at them anyway”. [P1]. Method 2: Interpretative Phenomenological Analysis Study Design Interpretative phenomenological analysis of semi-structured interviews was used to explore participants’ experiences of recovering from a traumatic event. Participants Eleven participants expressed an interest in the study and agreed to take part following receipt of the participant information sheet. Six of these participants had already taken part in the psychophysiological study. All participants were aged 18 or over and had experienced at least one traumatic event in their lifetime that they were willing to discuss. They also all described themselves as having recovered from their traumatic experience. The participant group comprised five men and six women aged between 26 and 60 years (mean = 43 years). All participants described themselves as of White ethnicity with 82% stating they were White British, one participant of White European ethnicity and one participant described their ethnicity as Welsh. TRAUMA AND RESILIENCE Measures 20 The participants completed the Life Events Checklist and PCL-C as in study one.

Multiple event types within an event category (e.g. physical and sexual assault) were not included. Resilience interview. The semi-structured resilience interview guide was developed by the researcher and piloted with a colleague who had experienced a mildly traumatic event in order to check comprehension, ease of use, sensitivity and relevance. In accordance with IPA methodology (Smith, Flowers & Larkin, 2009), the schedule was designed for flexible use with the interviewer exploring material raised by the participant. Recovery and resilience interviews took around 45 minutes to administer and were held individually and face-to-face. The schedule can be found in Appendix 7. TRAUMA AND RESILIENCE 21 Procedure Ethical approval was obtained and participant recruitment carried out following the procedure outlined for study one. Resilience interviews lasted around 45 minutes and were all conducted by the researcher, either at the laboratory or at the participant’s home or workplace. The investigator was a final year trainee clinical psychologist with significant experience of conducting sensitive or difficult interviews. The interview schedule was used flexibly with the researcher following up material raised by the participant. Given the potentially distressing nature of some of the material raised by participants the researcher used some supportive or normalising comments throughout interviews as appropriate. Interviews were digitally recorded. Interviews were spaced generously between participants to allow time for debrief, small talk and checking the participant’s experience of the interview and current mood and wellbeing prior to departure. Analysis Strategy Resilience interviews. The digital recordings of each interview were transcribed by the researcher and analysed using the interpretative phenomenological analysis (IPA) method (Smith, 2004; Smith, Flowers & Larkin, 2009). Following transcription initial impressions of the main points made by the interviewee were recorded. The process of analysis involved several re-readings of a transcript and coding of key phrases that best captured the point being articulated by the interviewee. Initial codes were then developed into a coding framework in which similar codes were merged and overarching themes identified. Each transcript and initial impressions were then re-read against the coding framework to ensure that the essence of the interviewee’s arguments were fully captured and the framework was refined during this process. Finally, for each theme, illustrative exemplar extracts were identified. Nvivo software (v.10) was used to assist with this procedure. TRAUMA AND RESILIENCE 22 Maintaining research quality. One resilience interview transcript was analysed by a second trainee clinical psychologist with experience of using IPA methodology and principles. The initial impressions, key phrases and themes identified by both researchers were compared in order to explore whether a similar understanding of the key elements of the participant’s experience had been reached (see Appendix 9). The final thematic model was discussed with an experienced IPA researcher and the identified themes were discussed with a group of clinical psychologists experienced in working with trauma survivors. A reflexivity statement can be found in Appendix 10. Results 2: Interpretative Phenomenological Analysis Study How did trauma resilient and recovered individuals cope with and respond to their trauma experiences? Qualitative analysis. The experiences discussed by the trauma survivors included traffic accidents (n=4), domestic violence (n=1), contraction of the life-threatening condition necrotizing fasciitis (n=1), being attacked by an animal (n=1), unlawful death of a child (n=1) and exposure to personal high risk and managing situations where people have died in the military, police, fire and prison service professions (n=3). Some individuals talked about a period of initially developing a trauma reaction, such as PTSD, heavy alcohol consumption or an eating disorder and then recovering, whilst others felt they recovered from the event almost immediately. Five thematic groups were identified as important in recovering from trauma. The first three, Attitudes and beliefs, Emotion regulation and Developing narrative were classified as internal factors, predominantly influenced by the individual. Support and Recovery by contrast are more externally determined. These factors operate most effectively when they are mutually reinforcing, for example TRAUMA AND RESILIENCE 23 with a social support network encouraging self-care and co-facilitating the development of a narrative that is consistent with the individual’s positive beliefs. Figure 4 illustrates the dominant thematic groups and contributory sub-themes. Figure 4. Model Illustrating Dominant Thematic Groups and Contributing Sub-themes. Attitudes and beliefs. This thematic group comprised the sub-themes of positivity, responsibility and a sense of control. Positivity included specific comments about the use of humour to cope, learning from the dramatic experience and describing oneself as lucky, as well as general positive beliefs about self and the world. One participant identified humour as the single most important factor in their ability to cope. “And I think that’s what I’ve found, if you’ve got a good team around you, I think humour will get you over it. Er, I think that’s, I think that’s the biggest thing for me, humour. Cause a lot of your mates will be, ah, you know, if you don’t come back can I have your boots.” [P10]. TRAUMA AND RESILIENCE 24 The positivity sub- theme was also displayed throughout the transcripts, with many participants laughing at some point when recounting their experience. This was absent for participants who initially struggled after their trauma when they described that period and then became present when they talked about their recovery. An element of positivity was found by participants even in the most difficult and apparently hopeless situations. “And I try and explain that to the new lads, who, especially with the fire [service], always remember that you’re helping someone, and you’ll always leave a situation better than you found it. Erm, regardless of the outcome, it’ll always be, even up to, you know I said about, if you are dealing with a deceased person, you know, we’ll look after that body until, so we’re always, for peace of mind you always know that you’ve done the best that you can.” [P9]. Responsibility involved a strong sense of concern for others, which was reflected in some narratives as an immediate reaction by the participant, despite they themselves being injured or still in some jeopardy. Some participants also spoke about a sense of responsibility for the traumatic event empowering their recovery. “So it, um, the strength I had to get myself through it was, it’s your own fault that this has happened, now, just carry on and get on with what you’ve got to do.” [P2]. Another participant, who initially struggled to cope with her traumatic experience, resorting to heavy alcohol use, identified the point at which somebody bluntly pointed out the consequences of their behaviour on her child as a key moment in beginning her recovery. She identified how her efforts to cope for her daughter gradually led to a genuine increase in ability to cope. TRAUMA AND RESILIENCE 25 “well obviously once I got [my daughter] back I had to sort myself out. I couldn’t live the way I had been living you know? So that was definitely a turning point…’cause it was a case of having to sort myself out. Or at least pretend I was. And I guess with, over time, I did in a way make myself feel better. I don’t know.” [P6]. The final sub-theme of the attitude and beliefs theme, sense of control, was cited by participants as important and, similarly to concern for others as above, a turning point in one participant’s recovery when she described suddenly realising that she could make a difference as important in developing resilience. “And that was the turning point because that was the first time that I ever fought back. And it suddenly realised, to me, that I do have the power to do something about it and that I’m no longer willing to put up with this kind of situation anymore.” [P8]. Emotion regulation. The second internal factor was Emotion regulation. Participants described using distraction from their traumatic experience or subsequent physical pain, such as curiosity, escapism and the ability to focus on something else, as helpful. “I remember looking around the ambulance and wondering, ooh, what does some of this equipment do kind of thing.” [P1]. “But, it wasn’t until I was going down to the theatre when they sort of laid the arm in, not like a tray but, I was still slightly attached to it, but it was going down there and it’s amazing what goes through your head. Because I’m a great Formula One fanatic. And all I was thinking about was who’d won the French grand prix because I’d missed out on that going to the show that day. So I’d obviously switched right off about what was happening to me there.” [P2]. TRAUMA AND RESILIENCE 26 Participants also expressed their emotions both in terms of describing their behaviour following their experience and also during the interview, occasionally becoming tearful or showing a change in vocal tone when recounting an annoyance or irritation. Both of these factors were present but more extreme in transcripts where participants had struggled initially to cope, with distraction escalating to denial, avoidance or an extreme preoccupation with other activities in order to block memories of the traumatic event. “I thought it would be a really good idea to copy every person’s music CD that I knew and I ended up literally all day every day just copying CDs. It was really not normal. And it was just literally to keep me busy. And I did that for a long period of time, before I finally went off sick, it was I’ve got to keep my brain busy.” [P7]. Similarly, with expressed emotions, some participants who initially struggled after their trauma reported quite volatile emotions during that period. Rumination was a more clear-cut variable with participants not dwelling on their experience as they recovered. Finally and perhaps most importantly, acceptance came across strongly in the transcripts, with participants allowing reminders of the event, not trying to force themselves to recover more quickly, and not blocking emotional experiences. Participants described acceptance as being both a cognitive and an embodied process, referring to the need to accept the facts of the situation as well as the emotions associated with the experience in order to move forwards. “And I remember one day thinking well I have two choices here, either accept this or not, and if I don’t then that’s going to be a massive, er, it’s going to make it all much harder, than if I accept it. And I think that was the day I said, okay, what’s happened. It was like I really have to start getting TRAUMA AND RESILIENCE 27 with what’s happened. It’s not a dream, I’m not going to wake up and be in a different place. This is reality and this is what I kind of need to come to terms with.” [P5]. “With fear, it’s like, the fear is worse than the reality, always. And I think you learn, the more you have been in that situation… So over time you learn, yeah, to accept it, I don’t want to do it but actually I know it’s going to be alright…I understand the fear and it’s, that’s the, the reason that I’m fearing it is that it’s preparing me for something. If I didn’t have it, it’d be wrong. Um, so I use it as a positive.” [P9]. Developing narrative. The third internal factor was the story, or narrative, the participants developed around the experience. Participants described having a complete understanding of their incident as important in helping them close the episode and move forwards. “I realised very quickly within five minutes oh it’s just an accident, that’s it, done and dusted, I know what the problem is. Erm, I know the reasons. I’ve got my timeline. There’s nothing else to find out. No problem there.” [P1]. Participants referred to the importance of understanding the story of the incident and some described how this was achieved by discussing their experience with friends or, in some cases, people who had undergone similar experiences, or professionals. One participant explained how simple repetition was not sufficient for a beneficial effect to occur, the recipient needed to be genuinely interested and, in all likelihood, help co-construct the narrative by validating and reinforcing key points. The importance of this theme was also illustrated by its absence in accounts of participants who had taken a longer time to recover. TRAUMA AND RESILIENCE 28 “And not knowing [what happened] makes me, upsets me. Like I think if he just said to me, this is what happened, I didn’t mean it to happen, that would make it better. But it’s the not knowing.” [P6]. Support. Two external themes were identified: Support and Recovery. Some participants described an almost immediate and competent response to their situation which resulted in feelings of comfort as well as practical assistance. It may be that this response reduced the length of time that those individuals felt alone and highly distressed, and enabled the development of the trauma narrative at an earlier point, as well as reinforcing positive beliefs. “I think knowing there were people there that were concerned about me that had never met me before. It was really nice to know that there was that help there in society. You know, I’ll get out of my car, be five minutes late for work just to help this chap out.” [P1]. “I remember feeling really, like, happy that someone had because I didn’t know what to do, I was totally, like, in shock and panic and I think, I feel like I would have just sat there for ages until someone had done the next step because I didn’t, I didn’t feel like, I knew that I should get out of the car because of all this traffic as well, and yeah, I felt really relieved that he had taken control of the situation. Because he’d ring the police and he was very, like, it’s okay, you’re alright and he was being very, um, calming I suppose, effect, yeah.” [P3]. Some participants described the importance of having people they could access who would understand the situation they had been in and who held similar beliefs to themselves about that type of experience. Therefore support was a more subtle and complex construct than simply the availability of friends or family. Some participants described situations in which partners or family members were not people they could speak to about their experience. These individuals could feel isolated despite TRAUMA AND RESILIENCE apparently having social support structures around them, although this could be mitigated by the 29 presence of an appropriate confidante. Being unable to talk to somebody about the experience was very negative. Several participants referred to the sense of taboo around their trauma experience as inhibiting them from feeling able to find a sympathetic listener and a sense of relief when this was overcome. “I got involved with a, er, erm, like an abuse group. Where I was with people who were like minded. And it’s amazing how you suddenly realise you’re not alone…because it’s amazing how, you talk to somebody but a lot of subjects are taboo subjects. But you talk about it to someone and they say oh I went through that and then automatically you’ve got a common bond.” [P8]. “I think it was, this is going to sound almost disrespectful for her [counselling] role but I think it was as much as anything, just someone there that I could, erm, release all this, these thoughts and the story if you like that I just needed to get out there.” [P7]. Recovery. The environment was an important feature of recovery, either in terms of removing the participant from places or people associated with the trauma, or by providing access to people and activities who enabled recovery. Participants used a range of self care techniques to help themselves heal. Achieving an acceptable quality of life and being able to return to previous activities were elements of recovery, however participants did not either force themselves to take up an activity associated with their trauma, such as driving, before they felt ready or decide not to return to it. “I mean, I’m cycling again now, I couldn’t, I never really cycled properly since I had my accident. I used to cycle, but, I’ve started cycling now, I’ve got a running blade, which I’m trying to run on, I’m not fit enough yet to, um, I’m never going to make the Olympic squad but it’s kind of a nice feeling to know, I can try it again now.” [P4]. TRAUMA AND RESILIENCE 30 General Discussion This study used a combination of qualitative interviews and psychophysiological measurement (heart rate response) to explore how trauma survivors with and without PTSD responded to a series of trauma-related picture stimuli. The study further explored coping by analysing trauma survivors’ accounts of how they either initially responded resiliently or recovered over time from their traumatic experience. The study revealed two major findings. Firstly, it identified individual differences in the use of emotion regulation strategies by participants when presented with a series of trauma-related stimuli. The second major finding was that five thematic groups were identified which participants described as assisting trauma resilience or recovery. Although some of these have previously been identified as important, such as social support (e.g., Weiss, 2011), this study indicated that these variables have particular attributes which determine whether or not the potentially beneficial effect is realised. This finding potentially explains why some variables which have been associated with resilience have low explanatory power when measured in general rather than specific terms. This study explored the feasibility, acceptability and usefulness of a phenomenological psychopathology multi-method design in PTSD research and concluded that whilst acceptability seemed good, there were difficulties with feasibility, especially in terms of recruitment of the PTSD group. Acceptability may have been influence by the researcher using excessive caution in the selection of trauma-related stimuli given that most participants described the images as invoking mild or negligible emotional impact. More highly arousing stimuli may also have been considered acceptable by this group. The process interview analysis identified individual differences in strategies associated with emotional regulation reported by the participants following their viewing of the trauma-related stimuli. Some of these strategies, such as avoidance and acceptance, were discussed by participant interviews in TRAUMA AND RESILIENCE 31 the IPA study. For example, in some interview accounts, participants who recovered psychologically from their trauma experiences almost immediately and did not develop PTSD or other reactive conditions described blocking or avoiding their trauma experience at the time it was taking place. These participants spoke about how they had distracted themselves with focus on peripheral detail and turning attention from self to others in the initial phase. However, when the period of crisis had passed, participants then described a process of accepting both factual and emotional information about the trauma. Participants who described remaining in the avoidance phase also recollected slower recovery journeys and early periods of trauma reactions, such as PTSD or a general struggle to cope. For these participants, the move towards acceptance came later and was associated with their eventual recovery. Therefore blocking or avoidance strategies may be protective and helpful in the short term but become problematic when individuals are unable to move on from that state. These findings potentially support Mancini and Bonnano’s (2006) suggestion that resilience to adversity may be achieved by means that are potentially maladaptive under what they term normal circumstances, such as dismissive coping styles, by suggesting that for some participants in this study, use of such strategies was initially helpful for them. These findings have begun to illustrate the complexity of PTSD and trauma recovery, which may explain some of the difficulties in the literature with the identification of many significant variables but limited explanatory power of individual variables. Social support, for example, has been consistently found to be positively associated with recovery (Weiss, 2011). However, participants in this study were clear that social support in itself was not sufficient to aid their recovery process. Although social support was very important, it needed to contain particular elements, for example, access to supportive individuals who would co-facilitate and reinforce a developing narrative in which TRAUMA AND RESILIENCE 32 the positive beliefs of the individual were encouraged, legitimised and shared. Simply recounting the trauma to others was not in itself helpful and neither was the presence of supportive individuals if they were unable or unwilling to understand and empathise with the trauma survivor, or had a different idea about how the survivor should cope. This was also an example of how, in fast recoveries, the thematic areas worked together. The finding that participants often recounted receiving immediate support after their trauma, often from strangers who witnessed the event and stopped to assist, has been described as a sub-theme in the support thematic group. However, that experience may also have influenced other themes. The fact of a stranger demonstrating altruism can also reinforce positive beliefs about the world as fundamentally safe and supportive and that the individual was not alone. The reassurance provided by the supporter can assist with emotional regulation by calming and soothing the trauma victim. The relational interaction between victim and respondent can also be seen as the early development of the trauma narrative with participants and respondents working out together what just happened and the respondent emphasising that the victim is now safe and further help is on its way. The inclusion of participants who recovered over a longer time period and in some cases initially struggled to cope with their traumatic experience was useful in developing the thematic groups as often these factors were absent during the initial, difficult period and then started to be spoken about when the participants described their shift from struggle to recovery. The heterogeneity of trauma experiences was also useful in developing confidence in themes that were present across different accounts. Although IPA researchers are generally encouraged to focus on homogenous populations (Smith, Flowers & Larkin, 2009), a limitation of PTSD literature has been the frequent examination of atypical groups, such as the military, which does not allow for confidence in generalizability of findings and results in over-representation of middle-aged males (Pole, 2007). TRAUMA AND RESILIENCE Strengths and Limitations 33 The methodology employed in this study has demonstrated the possibility of extending understanding of psychophysiological research into PTSD and resilience. The inclusion of qualitatively analysed process interviews resulted in unexpected findings and subsequent generation of future hypotheses for larger scale quantitative testing. The phenomenological approach can also be justified given the complexity of the PTSD construct and subsequent difficulties in the literature in terms of attempting to explain variance through broad concepts such as social support. This study suggested that social support is an important factor in recovery and resilience but that its usefulness is determined by specific attributes and perceptions. Limitations of the research include the lack of statistical power in the psychophysiological study which prevented multivariate analysis being conducted. Although this element of the research was intended as exploratory, a larger study may have been able to permit statistical hypothesis testing. However this was beyond the scope of the current research project. The study was also limited by the lack of a specific psychometric measure of resilience and reliance instead on lack of current PTSD symptomatology as indicative of resilience. This was partly due to the concerns about adequacy of available resilience measures (e.g. Bonnano et al., 2011). A further limitation was the lack of ethnic diversity in the participant sample, which did not allow for exploration of ethnicity as a variable, despite calls in the literature for this to be included in future research due to potential importance (e.g. Pole, 2007, Mancini and Bonnano, 2006). Limitations of the qualitative analyses were the potential for bias in the process interview analysis and the reliance in the IPA analysis on retrospective self-report data, with some participants describing traumas that had taken place many years previously. TRAUMA AND RESILIENCE Future Directions 34 This novel study design therefore offers possible hypotheses for future research. The finding that individuals do appear to use different coping strategies when confronted with trauma-related cues may help to explain why previous single method studies have produced such mixed outcomes (see Pole, 2007). Coping strategy style may be a factor which influences psychophysiological response to such stimuli. The identification of some coping styles in the laboratory which were independently reported by participants in the IPA study also demonstrates the value of comparing experimental data with self-report of actual life events. This integration could potentially be tested in a design where trauma survivors provided psychophysiological and process interview data in response to idiographic trauma cues and separately discussed the same traumatic incident in a qualitative study. This would allow comparison of response to the same trauma both physiologically and in terms of participant recollection. Given the identification of individual differences in use of emotion regulation strategies when exposed to trauma cues highlighted in this study, it may be useful for future research to adopt the methodology piloted here in an appropriately powered study. An improvement to the design might be to record participants describing out loud their thoughts and reactions to the stimuli during viewing in order to minimise any loss of data through recall afterwards. It might also useful to increase trauma stimuli severity, either through use of more highly arousing pictures or video material, in order to potentially evoke greater use of emotion regulation strategies, being mindful of ethical issues. The thematic model developed from the IPA study might explored further through similar analysis of interviews with PTSD sufferers, in order to identify whether their narratives reflect an absence of the identified thematic groups, either interacting or operating in isolation. Future analyses TRAUMA AND RESILIENCE 35 may also benefit from recruiting a participant sample where time elapsed since the traumatic incident is controlled, in order to reduce potential recall errors. Practical Implications The IPA analysis has the potential to inform a useful guide for healthcare professionals or support personnel within an employer such as the police service, responding to individuals who have experienced a traumatic event. The themes identified could be translated into a checklist as illustrated in Table 5. Table 5 Checklist for Healthcare Professionals Developed From Identified Themes Theme Checklist for healthcare professionals Attitudes and beliefs Does the individual volunteer any positive aspects of their experience (e.g. describe themselves as “lucky”), do they describe any sense of control (e.g. ability to prevent repeat of event), do they describe concern for others? Emotion regulation Whilst some greater than usual fluctuation is normal, does the individual describe feeling very emotionally volatile? Are they engaging in activities to block out memories or feelings, or spending a lot of time thinking about the trauma over and over again? Developing narrative Can the individual describe the event coherently from beginning to end? Are any parts of the narrative missing or unknown to them? TRAUMA AND RESILIENCE Support and safety 36 Did anybody come to the immediate aid of the individual, and did they find this supportive? Are they discussing the event with friends or family and if so are they finding this helpful? Do they feel isolated? Are they in touch with anybody who has experienced a similar event to themselves? Are they experiencing pressure, e.g. to return to work before they are ready? Recovery Is the individual generally looking after themselves, resting and not putting themselves under pressure to recover? Are they still in an environment where they are regularly reminded of the event or feel it could re-occur? This may assist healthcare professionals or employers who come into contact with people or staff who have experienced a traumatic event in the days afterwards to develop an understanding of which individuals are likely to require further support and which have the appropriate elements in place to support recovery. The analysis also has implications for treatment for individuals who have developed a reaction to their traumatic experience. Current National Institute of Clinical Excellence guidelines (NICE, 2005) recommend trauma-focussed cognitive behaviour therapy for PTSD and one element of this treatment is the focus on “hotspots” in the trauma narrative to help the individual re-process these from sensory to autobiographical memory. This study would support the importance of that intervention. The study also has implications for narrative therapeutic approaches, such as the potential benefit of helping the individual to strengthen positive beliefs and sense of control in their identity as well as TRAUMA AND RESILIENCE 37 working directly with the trauma narrative. Finally the importance of self-care in the recovery theme might indicate that compassionate-focussed approaches (e.g., Gilbert, 2009) could be helpful. Finally there are practical implications for people who respond directly to traumatic situations, such as emergency services personnel, given their potential role in beginning the process of narrative development for the trauma survivor. Concluding Comments PTSD and resilience are complex phenomena. In the same way that models of PTSD have often been confused by the presence of opposing extremes, hypo- and hyper-arousal, often found within the condition, so the difficulties in clearly understanding variables which contribute towards resilience may be explained by the dynamic process of recovery. Furthermore some variables, such as social support, appear to require quite specific attributes for the beneficial effect to be accessed. Mixed-method approaches may continue to be useful in developing understanding of these concepts. TRAUMA AND RESILIENCE 38 References American Psychiatric Association. (1994).

Personal assistance also is available by calling 434-817-2040, x167. 2. Three paper formats are accepted. All word counts should include references, tables, and figures. Regular articles (no longer than 6,000 words) are theoretical articles, full research studies, and reviews. Purely descriptive articles are rarely accepted. In special circumstances, the editors will consider longer manuscripts (up to 7,500 words) that describe complex studies. Authors are requested to seek special consideration prior to submitting manuscripts longer than 6,000 words. Brief reports (2,500 words) are for pilot studies or uncontrolled trials of an intervention, case studies that cover a new area, preliminary data on a new problem or population, condensed findings from a study that does not merit a full article, or methodologically oriented papers that replicate findings in new populations or report preliminary data on new instruments. Commentaries (1,000 words or less) cover responses to previously published articles or, occasionally, essays on a professional or scientific topic of general interest. Response commentaries, submitted no later than 8 weeks after the original article is published (12 weeks if outside the U.S.), must be content-directed and use tactful language. The original author is given the opportunity to respond to accepted commentaries. 3. The Journal follows the style recommendations of the 2010 Publication Manual of the American Psychological Association (APA; 6th). Manuscripts should use non-sexist language. Files must be formatted using letter or A4 page size, 1 inch (2.54 cm) margins on all sides, Times New Roman 12 point font, and double-spacing for text, tables, figures, and references. 4. The title page should include the title of the article, the running head (maximum 50 characters) in uppercase flush left, author(s) byline and institutional affiliation, and author note (see pp. 23-25 of the APA manual). 5. An abstract no longer than 200 words follows the title page on a separate page. 6. Format the reference list using APA style: (a) begin on a new page following the text, (b) doublespace, (c) use hanging indent format, (d) italicize the journal name or book title, and (e) list alphabetically by last name of first author. If a reference has a Digital Object Identifier (DOI), it must be included as the last element of the reference. Journal Article Kraemer, H.C. (2009).

Tables should be numbered (with Arabic numerals) and referred to by number in the text. Each table and figure should begin on a separate page. Only black and white tables and figures will be accepted (no color). Figures (photographs, drawings, and charts) should be numbered (with Arabic numerals) and referred to by number in the text. Place figures captions at the bottom of the figure itself, not on a separate page. Include a separate legend to explain symbols if needed. Figures should be in Word, TIFF, or EPS format. 8. Footnotes should be avoided. When their use is absolutely necessary, footnotes should be formatted in APA style and placed on a separate page after the reference list and before any tables. 9. The Journal uses a policy of unmasked review. Author identities are known to reviewers; reviewer identities are not known to authors. During the submission process, authors may request that specific individuals not be selected as reviewers; the names of preferred reviewers also may be provided. Authors may request blind review by contacting jots@ucsf.edu prior to submission in order to provide justification and obtain further instructions. 10. Statement of ethical standards: All work submitted to the Journal of Traumatic Stress must conform to applicable governmental regulations and discipline-appropriate ethical standards. Responsibility for meeting these requirements rests with all authors. Human and animal research studies typically require approval by an institutional research committee that has been established to protect the welfare of human or animal subjects. Data collection as part of clinical services or for program evaluation purposes generally does not require approval by an institutional research committee. However, analysis and presentation of such data outside the program setting may qualify as research (i.e., an effort to produce generalizable knowledge) and require approval by an institutional committee. Those who submit manuscripts to the Journal of Traumatic Stress based on data from these sources are encouraged to consult with a representative of the applicable institutional committee to determine if approval is needed. Presentations that report on a particular person (e.g., a clinical case) also usually require written permission from that person to allow public disclosure for educational purposes, and involve alteration or withholding of information that might directly or indirectly reveal identity and breach confidentiality. 11. Reports of randomized clinical trials should include a flow diagram and a completed CONSORT checklist (available at http://consort-statement.org/resources/downloads). The checklist should be designated as a "Supplementary file not for review" during the online submission process. As of 2007, the Journal of Traumatic Stress now follows CONSORT Guidelines for the reporting of randomized clinical trials. Please visit http://consort-statement.org for information about the consort standards and to download necessary forms. 12. Submission is a representation that the manuscript has not been published previously and is not currently under consideration for publication elsewhere.

(Chair, Departmental Ethics Committee) 52 TRAUMA AND RESILIENCE 53 TRAUMA AND RESILIENCE 54 TRAUMA AND RESILIENCE What would taking part involve? 55 We will send you some questionnaires to complete so that we can find out some basic information about you and some details about your traumatic experience(s) and what level of post-traumatic symptoms you have experienced. When these have been returned, we will contact you to arrange an appointment for you to take part in our experiment. If you would prefer, you can complete these with the researcher rather than on your own. During the experiment, you will be asked to look at some different pictures while we measure how your body responds to the pictures using a piece of laboratory equipment that measures your heart rate. Some of the pictures will be of a traumatic nature and the same type of trauma that you experienced in real life (for example, a car crash scene). We will then ask you some questions about your experience of looking at the pictures. We will check that you are feeling okay and answer any questions you have before you leave. If you are one of the people who has experienced a serious life trauma but had few or no posttraumatic symptoms, we will arrange another appointment to interview you about why you think you did not suffer these symptoms after your trauma. This interview will take under an hour and will be recorded so that we can type it up. How long would the questionnaires take to complete? The questionnaires that you are sent will take about 45 minutes to an hour to complete in total. Do I have to take part? No, the study is completely voluntary. Can I change my mind? Yes, you can change your mind at any point up until the results of the study are written up (March 2013). Simply contact one of the researchers and your information will be removed. What are the benefits and risks if I take part? The benefit is just the opportunity to contribute to a better understanding of trauma and resilience, which will hopefully improve support for people who experience serious traumas in future. The risk is that you may feel upset by reminders of your traumatic experience. We will check with you that you feel okay before you leave, and if needed put you in touch with agencies who can provide support. Do you pay travel expenses? Yes. Travel expenses will be reimbursed and travel by car is paid at 40p per mile. TRAUMA AND RESILIENCE 56 What will happen to the information I provide? You will be assigned a reference number for use during the study so that your identity is kept anonymous except from the researchers. A confidential document which records personal data and reference numbers will be kept securely stored at the University of Exeter which can only be accessed by the researchers. The results you provide will be reported anonymously and you will not be identified. Who can I contact if I feel upset after taking part in the study? Please be reassured that people who agree to participate in this type of research are not usually upset afterwards. However, in the unlikely event that you do feel upset or distressed, please contact the researcher. If you would like support from an external organisation, you can contact the following groups: Samaritans 08457 90 90 90 (24 hours) ASSIST (Assistance Support & Self-Help in Surviving Trauma) 01788 560800 Funded prize draw The University of Exeter will be funding a prize draw at the end of the study to thank participants for taking part. All participants who wish to be included will be entered into a prize draw with three prizes of either a £75, £50 or £25 high street voucher. The draw will take place in April 2013 and winners will be contacted by the researcher with their prize.

Running Head: TRAUMA AND RESILIENCE 65 Comparison of IPA Analyses Transcript 6 was reviewed by the author and a second trainee clinical psychologist who was familiar and experienced with IPA philosophy and methodology. Transcript 6 was the account of a female participant who had experienced the unlawful death of one of her children. The participant did not witness the death but found out about it shortly afterwards and attended hospital with police where she saw her daughter’s body. The child’s father was later imprisoned for manslaughter. The participant described struggling to cope in the couple of years following the death and experiencing alcohol and eating disorder difficulties, before recovering from her traumatic experience. Table 6 Comparison of IPA Analyses Author Analysis Second Analysis Matter of fact descriptions of traumatic events – indicative of developed narrative? Strong sense of shock – but noted use of the term “pretty awful” by the participant. Minimising? Sense of control important in Attitudes and Beliefs Sense of an absolute lack of control over the theme. situation itself and subsequently. Taboo subjects make it more difficult to access social support and co-construct narrative. How do you talk about something so horrific? Use of alcohol as a denial/ avoidance mechanism in early stages – Emotion regulation. Alcohol. The participant said “you can’t hide alcohol” – made me wonder what she might be hiding inside. Matter of fact in hindsight. “Just get on with it”. Evidence of further difficulties in accessing social support at the time. Referred to herself as a “fruit” – wondered what the reactions of others had been and whether she felt judged. Difficulty initially in making sense due to absence of a developing narrative – not aware of facts and unable to try and establish them as legal process had taken over. [Did not attend court after giving witness evidence as too distressed]. Balance between not being believed [by police initially] and not being able to believe her own memories – ongoing confusion. Sense of responsibility in Attitudes and beliefs theme. Doing it for others – trying to carry on for her second daughter. TRAUMA AND RESILIENCE 66 Reflexivity Statement The author previously worked in the prison service and met many staff and prisoners who had experienced significant trauma and showed diverse coping ability. Staff trauma was predominantly around previous military service or assaults within prison and prisoner trauma frequently involved childhood abuse and violence in prison. The author herself witnessed various violent incidents during this time. This interest in responses to trauma was intensified by an incident in which two prison officers were seriously assaulted with a weapon, which resulted in a rapid and seemingly full recovery by one officer and deterioration in functioning and development of PTSD by the other, who never returned to work. The author is familiar with the different theoretical models of PTSD and variables which influence resilience and during the interview process attempted to bracket these and set them aside in order to genuinely consider the participant responses and develop the model from their data rather than being influenced by top-down theory. TRAUMA AND RESILIENCE 67 Dissemination Statement Publications It is intended that the research paper will be submitted to the Journal of Traumatic Stress for consideration for publication. The author has been interviewed about the research findings for a feature article in Mental Health Nursing about resilience following trauma exposure in healthcare professionals. Presentations The IPA research findings have been presented to a group of psychologists working in a medium secure unit with individuals with extensive trauma histories. A presentation to colleagues, final year trainee clinical psychologists, at the University of Exeter is planned. A group of service users associated with the university contributed to the planning and design of the study and it is intended to present the research findings to them at a convenient date. The author has also been invited to present the research findings to the King's Centre for Military Health Research (KCMHR) / Academic Centre for Defence Mental Health (ACDMH).
