Impulsivity in BPD 4/11/2013 11:50:00 PM Emotional Cascades as Prospective Predictors of Dysregulated Behaviors in Borderline Personality Disorder – Selby, Joiner, 2013 I. A major symptom of borderline personality disorder (BPD) involves dysregulated behaviors, which have been defined as behaviors that are: difficult to control and result in harm to the individual or impairment in functioning, especially when engaged in on a chronic basis (Selby & Joiner, 2009). These behaviors, although not restricted to those with diagnoses of BPD, have been found to be prevalent in BPD psychopathology and can include non-suicidal self-injury (NSSI; Brown et al., 2002), binging and purging (Cassin & von Ranson, 2005), substance use (Bornovalova, Lejuez, Daughters, Rosenthal, & Lynch, 2005), shoplifting, reckless driving, and impulsive spending. II. Many of these behaviors have been found to have emotion- regulating properties (among many different motivations for different behaviors) and people often report engaging in these behaviors as a method of reducing or avoiding the experience of negative emotion (Selby & Joiner, 2009). Dysregulated behaviors, in this model, may then be used to distract from rumination through shifting attention to intense physical sensations. These physical sensations may vary according to the behavior, but examples could include feelings of pain or the sight of blood in NSSI (Nock, Joiner, Gordon, Lloyd-Richardson, & Prinstein, 2006), or the tastes or textures of food or feeling of fullness in binge eating (Mitchell et al., 1999). Decreases rumination – immediate feelings of relief. Behavior caused by emotional cascade, including rumination, less effective distractions may not pull attention away from the problem enough to bring emotional relief. because BPD is highly characterized by a wide range of dysregulated behaviors and frequent lability of emotion, BPD may be viewed as the extreme continuum of emotional cascades. III. Study A. Method 47 female participants, with self-report of dysregulation, some with BPD. Inclusion Criteria: 1) a report of four or more dysregulated behaviors (any combination), which were “difficult to control” over the last 2 weeks (NSSI, arguments, physical fights, binge eating, marijuana use, alcohol binges, impulsive shopping, throwing things, reckless driving), and 2) no imminent risk of suicide, 3)endorsed at least five BPD symptoms. PDA to alert participants five times a day. Participants were to rate their positive and negative emotions at the current moment. Also were to record their rate of rumination about the problem. Participants were asked whether they had engaged in any of the following since the previous signal: NSSI, alcohol use, marijuana use, physical fights, reckless driving, impulsive shopping, binge eating, yelling, throw- ing something, slamming a door, hanging up on someone, and insulting someone. B. Results BPD group rated higher on rumination than controls. Average participant reported ten dysregulated behaviors. BPD participants reported more dysregulated behaviors, as expected. Lag rumination was a significant predictor, whereas lag negative emotion was not. BPD symptoms, at high lag levels of lag-rumination and lagnegative emotion, significantly predicted increased probability of a behavior occurring (t � 3.39, p � .001). When the interaction was examined at high BPD symptoms, with high levels of negative emotion and low levels of rumination, the interaction was not significant (t � 1.44, p � .15). The interaction for high BPD symptoms with low negative emotion and high rumination also was not significant (t � 1.62, p � .11). a significant three-way interaction was found, which indicated that at high levels of negative emotion and rumination, those with BPD had an elevated probability of engaging in a dysregulated behavior beyond those with low levels of BPD symptom From Negative to Positive and Back Again: Polarized Affective and Relational Experience in Borderline Personality Disorder I. Dichotomous Thinking A. A hallmark feature of BPD is the tendency to evaluate one’s experience with extreme polarity (i.e., feeling all good or all bad), and with difficulty synthesizing disparate feelings into a complex, unified experience. Often termed dichotomous thinking (DT) or splitting, this phenomenon is considered to be a core feature of the disorder (Beck et al., 2004; Kernberg, 1975; Linehan, 1993) B. Criteria 4 and 5 (impulsive behaviors, suicidality and self-injury) may also be linked to highly polarized experiences as they are theorized to be, in part, consequences of heightened or extreme negative affect (APA, 2000; Stiglmayr et al., 2005). II. Impulsive Behavior A. Extreme swings in affective or relational experience can trigger risky/impulsive behaviors (e.g., self-injury, substance B. C. abuse) in an attempt to regulate moods associated with these experiences. Considerable evidence suggesting an important association between affect, relational experiences, and maladaptive behavior in BPD (e.g., Ebner-Priemer et al., 2007; Russell, Moskowitz, Zuroff, Sookman, & Paris, 2007; Selby, Anestis, Bender, & Joiner, 2009; Trull et al., 2008), alongside an ongoing debate as to whether these components should be thought of as independent factors (e.g., Glenn & Klonsky, 2009; Koenigsberg et al., 2001; Linehan, 1993). For example, Linehan (1993) and others have argued that the key underlying component of BPD is emotion dysregulation, and that other components, including relational instability and impulsive behavior, can be understood as concomitants of an underlying emotion-regulation disorder. Extreme increases in negative affect were moderated by selfinjurious behavior in BPD. Both pieces of evidence are consistent with theories suggesting that the risky/impulsive behaviors characteristic of the disorder are enacted as maladaptive yet powerful attempts at mood regulation when individuals become overwhelmed with negative affect (e.g., Beck et al., 2004; Linehan, 1993). II. Study Participants reported their affective and relational experiences as well as risky/impulsive behaviors commonly associated with BPD. Experimenters were particularly interested in exploring what impact interpersonal stress has on the polarity of self-reported experiences, and how polarity and interpersonal stress might be associated with risky/ impulsive behavior. Hypothesis: anticipate that greater polarity in affective and relational experience will be associated with increased rates of reported risky/ impulsive behaviors, and that this association will be strongest during high inter-personal stress. In this case, we would predict that during high interpersonal stress, relational polarity would have the strongest association to impulsive behavior and that during low interpersonal stress, affective polarity would have the strongest association. A. Procedure BPD group must meet six criteria for BPD. No symptoms for healthy control group. Psychotropic medication or BPD group was okay. 65 BPD, 61 healthy controls. B. PDA diaries For each diary entry, participants recorded affective experience, interpersonal stress, and if they had engaged in any of five domains of risky/impulsive behaviors. Also asked to identify one important person in their life, and asked to respond to a series of items assessing his or her relational experiences with this person across 6 items on a 5-point Likert scale (0 � not at all, 4 � extremely). Types of risky/impulsive behaviors: excessive spending, binge eating, risky sexual behavior, substance use and self-injury. B. Results - Polarity of relational experience was significantly associated with the rate of reports of impulsive behavior during high stress in the final model, such that the more polarized the relational experience, the greater the rate of reports of impulsive behavior. - During low stress, results indicated that the polarity of affective experience was significantly associated with the rate of reports of impulsive behaviors during low stress in the final model. - During interpersonal stress, polarity increased for the BPD group in contrast with controls. Finally, heightened polarity in affective and relational experiences was significantly associated with risky/ impulsive behaviors. - During heightened interpersonal stress, relational polarity was the sole predictor (beyond group) of impulsive behavior, whereas during low interpersonal stress, affective polarity was the sole predictor. Characteristics of Borderline Personality Disorder Associated with Suicidal Behavior Beth S. Brodsky, Ph.D., Kevin M. Malone, M.D., Steven P. Ellis, Ph.D., Rebecca A. Dulit, M.D., J. John Mann, M.D. American Journal of Psychiatry, Dec 1997; 154 (12); 1715-1719. Previous Studies: BPD is a distinct risk factor for suicidal behavior. Rates of suicide among patients with BPD range from 3% to 9.5%, 75% of an inpatient sample with BPD had made at least one previous suicide gesture. Earlier studies identified correlates of suicidal behavior in subjects with BPD that were NOT related to personality traits, such as age, educational level, and co-morbid axis I diagnoses of major depression, substance abuse, and eating disorders. The number of previous suicide attempts has been found to be the strongest predictor of suicide and future suicidal behavior in all psychiatric populations including subjects with BPD. These studies suggest the presence of Axis I affective and substance abuse diagnoses are insufficient to explain suicidal behavior among patients with BPD. Personality characteristics such as impulsivity and aggression have been found to correlate with suicide risk in other psychiatric populations. I. Method - To meet the impulsivity criterion, subjects had to endorse impulsive behavior in at least two areas of life: binge eating, shopping, gambling, substance use or reckless driving – EXCLUDED self-destructive behaviors such as suicide attempts or parasuicide behaviors. Information on lifetime history of suicidal behavior was obtained from 214 patients diagnosed with BPD. Authors examined the relationship between DSM-III-R criteria and the following measures of suicidal behavior: presence or absence of a previous suicide attempt, number of previous attempts, and lethality and intent to die associated with the most lethal lifetime attempt. This study was undertaken to examine the relationship of individual characteristics of BPD and overall severity of BPD to childhood abuse history and the relationship of both to the following measures of suicidal behavior: history of a previous suicide attempt, number of previous attempts, and intent and lethality of the most lethal lifetime attempt. II. Results Impulsivity was the only characteristic of BPD (EXCLUDING THE SELF_DESTRUCTIVE CRITERION) that was associated with a higher number of previous suicide attempts after controlling for lifetime diagnosis of depression and substance abuse. Global severity of pathology of BPD was not associated with suicidal behavior. History of childhood abuse correlated significantly with number of lifetime suicide attempts. Impulsivity may be a risk factor for future suicide attempt. Potential therapeutic target for prevention of future suicide attempts. Impulsivity was the one BPD characteristic significantly correlated with number of previous suicide attempts. In an analysis of covariance that controlled for major depression and substance abuse diagnoses, patients with BPD who met the impulsivity criterion had MORE past suicide attempts than those who did not meet the impulsivity criterion. Single trait of impulsivity, rather than global severity of BPD pathology, is associated with suicidal behavior in BPD. Studies looking at Suicide and Impulsivity- using NON SELF REPORT.

By inhibiting other potential responses through synaptic activity in the brain and vagal activity in the body, the CAN acts as a “neurophysiological command center governing cognitive, behavioral, and physiological elements into regulated emotion states.” Effective emotion regulation depends on being able to flexibly adjust your physiological response to a changing environment. Heart Rate Variability (HRV) is a measure of the continuous interplay between sympathetic and parasympathetic influences on heart rate that yields information about autonomic flexibility and thereby represents the capacity for regulated emotional responding. The central autonomic network (CAN) assists emotional regulation by adjusting physiological arousal to appropriately match the external and internal environments. The CAN consists of cortical, limbic, and brain-stem components. Its output is transmitted to the sinoatrial node of the heart, among other organs. HRV reflects the moment-to-moment output of the CAN and, by proxy, an individual’s capacity to generate regulated physiological responses in the context of emotional expression. (Thayer & Lane, 2000; Thayer & Siegle, 2002) THAYER – Psychosomatics and psychopathology: looking up and down from the brain. Role of Autonomic Nervous System in a wide range of mental diseases. 1. ANS Components: a. Sympathetic: Energy mobilization – fight or fight b. Parasympathetic – vegetative and restorative functions. calm Health is maintained through a balance of the symptoms. Large body of evidence to suggest that autonomic imbalance, typically the SYMPATHETIC SYSTEM is HYPERACTIVE (energy mobilization) and parasympathetic is hypoactive (calm, restorative) is associated with various pathological conditions. Prolonged state of alarm associated with negative emotions places an excessive energy demand on the system. Although a large range of physiologic factors determines heart rate, the ANS is most prominent. ANS MOST PROMINENT IN DETERMINING HEART RATE. CARDIAC VAGAL- THE PRIMARY SYMPATHETIC NERVE. ???? Resting cardiac autonomic balance favors energy conservation by way of parasympathetic dominance over sympathetic influences. ???? Does this mean that cardiac balance is achieved when parasympathetic system dominates??? Threat increases sympathetic ready for fight or flight. TONIC INHIBITION??? This inhibition (inhibition of sympathetic system???) is achieved via top down modulation from the pre-frontal cortex. Under conditions of uncertainty and threat, pre-frontal cortex becomes HYPO active. So prefrontal cortex is not really working strong during threat. Decrease in prefrontal cortex is associated with INCREASE in sympathetic = fight or fight= energy mobilization. However, when this state is PROLONGED, it produces excess wear and tear on the system components, know as allostatic load. ***** Pathological states such as anxiety, depression, ptsd, and schizophrenia are associated with LOW PREFRONTAL ACTIVITY and lack of inhibitory neural processes. This is seen by pre-attentive bias for threat information, deficits in working memory and executive function, and poor affective information processing and REGULATION.
