Abstract: This study examined abuse and trauma exposure as it predicted identity problems, affect dysregulation, and relational disturbance in 620 individuals from the general population. Multivariate analyses indicated that maternal (but not paternal) emotional abuse was uniquely associated with elevations on all 7 scales of the Inventory of Altered Self-Capacities (IASC): Interpersonal Conflicts, Idealization-Disillusionment, Abandonment Concerns, Identity Impairment, Susceptibility to Influence, Affect Dysregulation, and Tension Reduction Activities. Low paternal (but not low maternal) emotional support was associated with Interpersonal Conflicts, Abandonment Concerns, and Tension Reduction Behaviors. Paternal emotional support did not significantly decrease the negative effects of maternal emotional abuse. Sexual abuse was predictive of all IASC scales except for Interpersonal Conflicts and Identity Impairment. Noninterpersonal traumas and adult traumas were typically unrelated to IASC scales. Childhood emotional and sexual maltreatment—perhaps especially maternal emotional abuse—may be critical factors in the development of disturbed self-capacities. Interpersonal victimization, whether physical, sexual, or psychological, is relatively common in North America and is associated with a variety of immediate and longer-term psychological symptoms. Those who have been maltreated in childhood or in adulthood, for example, are at risk for subsequent anxiety, depression, posttraumatic stress, various forms of dysfunctional behavior, substance abuse, dissociation, and even, in some cases, psychosis (Briere, 2004; Herman, 1992; Myers et al., 2002; van der Kolk et al., 2005; for reviews). Several Diagnostic and Statistical Manual (DSM-IV) diagnoses (i.e., acute stress disorder, posttraumatic stress disorder, the dissociative disorders, and brief psychotic disorder with marked stressors) directly reflect the effects of traumatic life events on psychological functioning (American Psychiatric Association, 2000). Beyond these well-known symptoms of adverse experience, however, is another set of potential victimization effects, sometimes referred to as impaired self-capacities or self-disturbance. In contrast to the above symptoms and problems, this less-studied domain was initially rooted in psychodynamic theory (Kohut, 1977). Introduced to the trauma field by McCann and Pearlman (1990), and slightly modified by Briere (2000), the construct of impaired self-capacities may be viewed as comprising at least 3 separate but related types of disturbance: (a) problems in one's ability to access and maintain a stable sense of identity or self (identity disturbance), (b) an inability to regulate and/or tolerate negative emotional states (affect dysregulation), and (c) difficulties in forming and sustaining meaningful relationships with others (relational disturbance). Problems in these 3 areas may lead to significant psychosocial difficulties. Individuals with a less-coherent sense of self, for example, may lack the internal self-monitoring and self-awareness that would otherwise inform them about their feelings, thoughts, needs, goals, and behaviors, and may complain of emptiness, confusion about who they “really” are, suggestibility, contradictory thoughts and feelings, and an inability to set goals for the future (Hamilton, 1988; Kohut, 1977; McCann and Pearlman, 1990). Similarly, individuals with problems in affect regulation are often subject to emotional instability or mood swings, problems in inhibiting the expression of strong affect, and difficulties in terminating dysphoric internal states (Cloitre et al., 2006; Linehan, 1993; van der Kolk et al., 1996). In the absence of sufficient internal affect regulation skills, some people may respond with external behaviors that distract, soothe, numb, or otherwise reduce internal distress (Allen, 2001; Briere, 2002). Finally, individuals with relational problems often find themselves in conflictual or chaotic relationships, frequently have problems forming intimate adult attachments, may fear abandonment by others, and may engage in behaviors that are likely to threaten or disrupt close relationships (Collins and Read, 1990; Pearlman and Courtois, 2005; Simpson, 1990). Apropos of the breadth of such disturbance, a number of studies link impaired self-capacities (especially affect dysregulation) to a number of other symptoms and syndromes, including dysphoric mood, substance abuse, eating disorders, dissociation, and impulsive or selfdestructive behavior (Briere, 2006; Grilo et al., 1997; Stice et al., 1996; Zlotnick et al., 1997). More generally, self-related symptoms and dysfunctional behaviors are sometimes associated with borderline personality disorder (American Psychiatric Association, 2000, 2001) or, at lower symptom intensity, borderline traits or features. In fact, per the current DSM-IV (American Psychiatric Association, 2000, p. 710), borderline personality disorder can be viewed as a form of self-disturbance, involving problems in relatedness (e.g., “a pattern of intense and unstable interpersonal relationships”), identity (e.g., “identity disturbance: unstable self-image or sense of self”), and affect regulation (e.g., “affective instability due to a marked reactivity of mood”). Nevertheless, not all individuals who suffer from self-capacity disturbance meet criteria for this disorder, and may not always be well conceptualized from a personality disorder perspective (Briere and Scott, 2006; Herman, 1992). Although various modern writers have discussed some version of self-disturbance at length (Allen, 2001; Schore, 1994; Siegel, 1999; Stern, 1985), research on self-functions has lagged behind clinical interest. This relative paucity of empirical data is probably due to the complexity of the construct (as compared with, for example, anxiety or depression), the tendency for psychodynamic clinicians to focus less on empirical investigation than on clinical practice, and the unfortunately small number of standardized and valid psychological measures of selfcapacities available to researchers. As a result, the precise phenomenology of self-disturbance has not been well mapped nor have its antecedents been fully identified. Despite the limited research in the area, several studies suggest that self-capacity problems, symptoms of borderline personality disorder, or disturbed object relations are associated with childhood experiences of abuse or neglect (Alexander et al., 1998; Elliott, 1994; Herman and van der Kolk, 1987; Westen et al., 1990; Wilkenson-Ryan and Westen, 2000). The mechanism whereby child maltreatment may result in later self-disturbance is not entirely clear. However, various writers suggest that the growing child requires safety, stability, and emotionally attuned caretakers to develop a positive sense of self, affect regulation skills, and the capacity to form meaningful relationships (Allen, 2001; Bowlby, 1988; Fonagy et al., 1995; Stern, 1985). In agreement with both psychodynamic theory (Winnicott, 1965) and attachment theory (Bowlby, 1988), positive attachment experiences with maternal figures may have especially significant impacts on the growing child's self-development and eventual functioning (Liang et al., 2005; Schore, 1994). Child abuse and neglect reflects, almost by definition, the absence of this sort of positive childhood environment, and thus, may logically correlate with subsequent selfdisturbance. Although self-capacity problems appear to be relatively common among those abused or neglected as children, few studies in this area have examined the specific characteristics of adverse experiences over the lifespan as they predict this form of symptomatology. Specifically, there is very little published research on (a) whether impaired self-capacities are uniquely associated with childhood maltreatment as opposed to, for example, later trauma in adulthood, (b) whether the specific nature of the negative experience (e.g., sexual vs. emotional, or interpersonal vs. accidental) has a bearing on the development of self-disturbance, and (c) whether different forms of childhood (or adult) victimization are associated with different kinds of self-capacity problems. In response to these issues, the current study examined 3 hypotheses. First, we proposed that to the extent that self-capacities are rooted in relational dynamics, altered self-capacities would correlate to a greater extent with interpersonal victimization (e.g., child abuse or adult assault) than noninterpersonal trauma (e.g., accidents or disasters). Second, because self-capacities are thought to arise largely in the context of child–parent attachment experiences, altered selffunctioning was expected to be associated more with maltreatment in childhood than in adulthood. Finally, because the development of self-capacities is thought to be contingent upon emotional attunement between parent and child, childhood emotional abuse and lack of emotional support were hypothesized to have a stronger relationship to impaired self-capacities than childhood sexual or physical abuse. METHODS Procedure Data for the present study were taken from the normative sample of the Inventory of Altered Self Capacities (IASC; Briere, 2000), a multidimensional measure of disturbed self-functioning. After approval was obtained from the institutional review board of the University of Central Florida, a national sampling service generated a random sample of registered owners of automobiles and/or individuals with listed telephones in the general population, stratified on geographical location. Participants were mailed a questionnaire containing, among other measures, the IASC and the Traumatic Events Survey (TES; Elliott, 1992). Both the IASC and the TES are described below. Participants received $5.00 for completing the questionnaire. In addition, 70 university students were tested in the normative study with the same protocol (but without financial compensation) to provide additional participants in the lower age ranges. University student data were not included in the current analyses, however. All questionnaires were anonymous, although financial compensation in the general population sample was tied to names and addresses that were destroyed before data analysis was initiated. This study, conducted by the IASC test publisher (Psychological Assessment Resources), has resulted in several published papers (e.g., Briere, 2006; Briere and Runtz, 2002), as well as the IASC test manual (Briere, 2000). Participants Overall, 620 of 5415 potential participants completed the IASC in the standardization study. A smaller subgroup (N = 417, 7.7% of the potential sample) also completed the TES—probably owing to the relative length and complexity of the latter measure. The mean age of this subsequent group was 49.7 years (SD = 15.4), and 241 (57.8%) were male. Racial composition was 343 (82.3%) Caucasian, 24 (5.8%) African American, 14 (3.4%) Hispanic, 14 (3.4%) Asian, 12 (2.9%) Native American, 6 (1.4%) “other,” and 4 (1%) did not indicate their race. Measures Inventory of Altered Self-Capacities The IASC is a standardized, 7-scale test, developed to tap disturbed self-capacities in 3 areas: interpersonal relatedness, identity, and affect regulation (Briere, 2000). IASC items are rated according to the frequency of certain behaviors or experiences over the prior 6 months, using a 4-point scale ranging from 1 (Never) to 4 (Often). Specific scales are Interpersonal Conflicts (difficulties in maintaining important relationships), Idealization-Disillusionment (cycles of valuing then devaluing people), Abandonment Concerns (hypersensitivity to, and fear of, interpersonal rejection), Identity Impairment (difficulties in maintaining a sense of self and identity), Susceptibility to Influence (suggestibility and uncritical acceptance of direction or control by others), Affect Dysregulation (difficulties tolerating and regulating negative emotions), and Tension Reduction Activities (involvement in distracting external activities as a way to reduce painful internal states). Research suggests that the IASC is reliable and valid in general population, clinical, and university samples, and correlates as expected with other selfrelated variables, including fearful and preoccupied attachment styles on the Relationship Questionnaire (Bartholomew and Horowitz, 1991), borderline and antisocial features scales of the Personality Assessment Inventory (Morey, 1991), interpersonal problems on the Inventory of Interpersonal Problems (Horowitz et al., 1988), substance abuse and suicidality on the Detailed Assessment of Posttraumatic Stress (Briere, 2001), Impaired Self-Reference (ISR) on the Trauma Symptom Inventory (Briere, 1995), and inferred object relations on the Bell Object Relations and Reality Testing Inventory (Bell, 1995) (Briere, 2000; Briere and Runtz, 2002; Dietrich, 2003; Runtz et al., 2000). A factor analysis in the normative sample indicated that each of the IASC scales reflect a separate, self-related symptom dimension (Briere, 2000). TES The TES evaluates self-reports of up to 30 different childhood and adult interpersonal and environmental traumas. It has been used in various studies of abuse and trauma exposure (Briere, 2006; Elliott et al., 2004). Relevant to the current study, the TES includes questions on childhood and adult physical and sexual victimization, and includes 20-item Emotional Abuse-Maternal Figure and Emotional Abuse-Paternal Figure scales, each of which can be divided into Emotionally Abusive Behavior and Emotional Support subscales. Examples of items on the Emotional Abusive Behavior subscale, rated for the participant's “most difficult year” before age 18, are endorsements of a mother or father figure having “yelled at you,” “rejected you,” and “humiliated you in front of others.” Emotional Support subscale items (on which low scores indicate emotional nonsupport) include “showed you that she (or he, depending on the version) loved you,” “offered to help you,” and “encouraged you to have fun with friends.” Operational Definitions of Interpersonal Victimization and Noninterpersonal Trauma Four interpersonal victimization variables were examined in the present study, in addition to scores on the Emotional Abuse subscales of the TES. These were childhood sexual abuse, childhood physical abuse, adult sexual assault, and adult physical assault. Childhood physical abuse was categorized as present on the TES if the participant reported physical aggression by a parent or caretaker other than spanking, or any intentional parent/caretaker behavior that left a mark or injury; sexual abuse was indexed as any physical sexual contact from an adult or someone 5 or more years older than the participant, or any peer sexual contact that was physically forced. Adult physical assault was defined on the TES as being hit with a hand, fist, or object that resulted in marks, bruising, bleeding, burns, broken bones, or other serious injury. Adult sexual assault was defined as any sexual contact that occurred as a result of physical force or threats. Also based on the TES, 2 noninterpersonal trauma variables were evaluated: selfreported exposure to a natural disaster or to a serious accident. When either of these 2 variables was endorsed as positive, the participant was designated as having experienced a noninterpersonal trauma. RESULTS Across gender, 122 (29.3%) and 70 (16.8%) of participants reported childhood physical and sexual abuse, respectively, on the TES. Adult physical and sexual assault was reported by, respectively, 117 (28.1%) and 24 (5.8%) of all participants, and 272 (65.2%) reported exposure to 1 or more noninterpersonal traumas in their lifetimes. Scores on the Maternal and Paternal Emotionally Abusive Behavior scales were correlated (r = .67, p < .001) and statistically equivalent (M = 6.2, SD = 9.4 and M = 6.1, SD = 9.2, respectively; t[627] = 0.40, ns). Participants’ scores on the Maternal Emotional Support and Paternal Emotional Support, although also strongly correlated (r = .79, p < .001), were significantly different (t[627] = 11.8, p < .001), with maternal support being endorsed more than paternal support (M = 13.4, SD = 8.9, vs. M = 10.6, SD = 9.0). Multiple regression analysis was performed on each IASC scale, entering demographics, childhood sexual and physical abuse, maternal and paternal emotional abuse and level of emotional support, adult interpersonal trauma, and noninterpersonal trauma variables at step 1, followed by all 2-way interactions between participant gender and trauma variables at step 2. As indicated in Table 1, all IASC scales were predicted by a combination of demographics, child maltreatment, and adult interpersonal victimization at step 1. No interaction between gender and any maltreatment or trauma variable was found at step 2. TABLE 1. Multiple Regression of IASC Scores Using Age, Gender, and Trauma Variables, Step 1 (N = 417) SEE ORIGINAL ARTICLE FOR TABLES Participant age was associated with 1 IASC scale, Identity Impairment, with younger participants scoring higher in this area than older participants. Of the 6 child maltreatment variables, maternal emotional abuse was associated with elevations on all 7 IASC scales, low paternal emotional support was related to Interpersonal Conflicts, Abandonment Concerns, and Tension Reduction Activities, and sexual abuse was predictive of all scales but Interpersonal Conflicts and Identity Impairment. Adult physical assault was related to a single IASC scale, Tension Reduction Activities. Childhood physical abuse, paternal emotional abuse, low maternal emotional support, adult sexual assault, and exposure to noninterpersonal trauma were unrelated to any IASC scale. Because maternal emotional abuse and lack of paternal emotional support emerged as significant predictors of self-capacity disturbance, an additional set of analyses were performed to examine whether these 2 variables interacted to affect IASC scale scores—especially whether maternal emotional abuse effects were reduced in the presence of significant paternal emotional support. This was evaluated by entering a maternal emotional abuse × paternal emotional support interaction term into the multiple regression equations described above. Addition of this interaction term did not predict additional variance in any IASC scale score. DISCUSSION The current results suggest that impaired self-capacities are especially associated with adverse interpersonal—as opposed to noninterpersonal—events, and are largely restricted to child—as opposed to adult—maltreatment. The primary predictors of self-disturbance were childhood emotional abuse, emotional nonsupport, and sexual abuse. Specifically, Interpersonal Conflicts, Idealization-Disillusionment, Abandonment Concerns, Identity Impairment, Susceptibility to Influence, Affect Dysregulation, and Tension Reduction Activities were all associated with having been emotionally abused by a mother figure; Interpersonal Conflicts, Abandonment Concerns, and Tension Reduction Behaviors were associated with low levels of emotional support by a father figure; and all areas of self-disturbance except for Interpersonal Conflicts and Identity Impairment were associated with childhood sexual abuse. In contrast, adult traumas (other than physical assault) and adult exposure to noninterpersonal violence were not uniquely associated with any IASC scales. In the only finding for adult trauma, adult physical assault was related to a single IASC scale, Tension Reduction Behavior, perhaps suggesting that those who tend to “act out” or externalize emotional distress are at more risk for assault. The finding that maternal emotional abuse was especially related to self-disturbance is in agreement with data suggesting that mother–child relational disturbance is specifically predictive of later borderline symptoms (Salzman et al., 1997), and aligns with the work of Schore (1994), Siegel (1999), and Stern (1985), who view impaired self-capacities as at least partially the result of disrupted mother–child attachment. The reasons for the specific importance of maternal—as opposed to paternal—emotional abuse in the development of self-symptoms are not entirely clear. One possibility is that inherent, psychobiological factors may especially heighten the importance of the mother–child dyad (Bowlby, 1988), and thus the impacts of maternal emotionally abusive behavior when it occurs. Alternatively, or in addition, these findings may reflect the effects of sex-role socialization in North American society, wherein mothers are generally expected to be more involved in child rearing than fathers (Steil, 2000) and, thus, are likely to have greater relative impacts—in the absence of paternal involvement—when they emotionally maltreat their children. Paternal emotional responses were not unrelated to self-capacities, however. In 3 instances (Interpersonal Conflicts, Abandonment Concerns, and Tension Reduction Behaviors), the absence of emotional support by a father figure made an independent contribution to selfdisturbance, above and beyond maternal emotional abuse. These data represent a relatively new finding in the child maltreatment literature and potentially highlight the role of paternal emotional relatedness in children's self-development. If replicated, such data indicate that both maternal and paternal behaviors may affect self-functioning, in contrast to perspectives that focus primarily on maternal failings. They also suggest a possible new area of inquiry, i.e., the relative impacts of emotionally abusive behaviors versus the absence of emotionally supportive behaviors, perhaps especially in the context of parent gender. In the present study, maternal emotional support was more prevalent than paternal support, yet paternal nonsupport was the critical variable. Emotional abuse, on the other hand, was as prevalent in fathers as mothers, yet only maternal abuse appeared to be associated with symptoms. Unfortunately, although paternal support was associated with less self-capacity problems, high paternal support did not appear to reduce the negative effects of maternal abuse. The apparent primacy of childhood emotional abuse and nonsupport in self-capacity disturbance suggests its aversive nature and substantial impacts. As such, it may be appropriate to refer to significant emotional abuse or neglect as “traumatic” (Allen, 2001; Briere, 2006). However, because childhood emotional maltreatment does not typically involve a threat to bodily integrity, it does not constitute a trauma as defined by “Criterion A1” of the DSM-IV (American Psychiatric Association, 2000). Whether this definitional issue should be resolved in the direction of viewing emotional maltreatment as an adverse (but not traumatic) event, or, alternatively, as evidence that the current DSM-IV trauma definition requires further attention, awaits further consideration. In addition to the effects of emotional abuse and nonsupport, childhood sexual victimization was associated with several forms of self-related symptomatology, per other investigations (Elliott, 1994; Herman and van der Kolk, 1987). These results, however, contradict those of MessmanMoore et al. (2005), who found that adult exposure to sexual trauma was more related to ISR than was exposure to childhood sexual abuse. As Messman-Moore et al. note, their unexpected finding may be due to various factors, including the limited range of self-disturbance potentially present in their sample of university students, the temporarily self-destabilizing effects of acute sexual assault, and the possibility that the measure that they used (the ISR scale of the Trauma Symptom Inventory; Briere, 1995) may have been inadequate to tap the entire construct of selfdisturbance. Apropos of this last issue, the current study employed the IASC, which separates identity, affect regulation, and relational difficulties into individual scales—a strategy that may have advantages over a single summary scale such as the ISR, including greater differentiation of childhood versus adult victimization effects. The differential associations between some (but not all) forms of child maltreatment with certain (but not all) self-capacities in the current study suggests that it may be inappropriate to generalize that child maltreatment, per se, is related to adult self-capacity disturbance. Physical child abuse, for example, was not associated with any form of self-disturbance, whereas maternal (but not paternal) emotional abuse was a broad predictor of self-symptoms. Sexual abuse was intermediate in its effects: related to 5 of 7 forms of self-disturbance, but less powerfully predictive than maternal emotional abuse. Low paternal emotional support was associated with 3 of 7 symptom types, whereas low maternal support was unrelated to later self-dysfunction. Finally, although Interpersonal Conflicts and Identity Impairment were associated with maternal emotional abuse, neither was related to sexual abuse. These data emphasize the multidimensionality of both child maltreatment and adult self-disturbance, as well as indicating that certain forms of child abuse and neglect are potentially more impactful than others. For example, the current results suggest that childhood sexual abuse, although significantly related to impaired self-capacities, is second to the effects of childhood maternal abuse. Such data do not mean that sexual abuse is less than psychologically toxic, but rather that another form of child maltreatment—one less addressed in the literature—may be even more traumagenic. Additional study is clearly indicated to determine the reasons (whether biological, attachment-related, or sociocultural) for this specific effect. The relationship between certain forms of child maltreatment and later self-dysfunction suggests the potential benefit of addressing childhood emotional and sexual abuse in the treatment of selfdisturbance. This may include interventions that involve the activation and processing of negative abuse- or neglect-related self-schemas in the context of an ongoing therapeutic relationship (Briere and Scott, 2006; Pearlman and Courtois, 2005), and/or that focus on the specific results of such maltreatment, such as cognitive distortions, negative self-perceptions, and affect skill deficits (Cloitre et al., 2002, 2006; Follette and Ruzek, 2006; Linehan, 1993). In either instance, increasing clinical awareness of the possible maltreatment-related etiology of adult self-capacity disturbance is likely to increase the specificity of psychological interventions in this area. The present findings should be viewed in light of the methodology of this study. First, the sample consisted solely of nonclinical participants and thus may not generalize completely to clinically presenting individuals. Because the level of both trauma exposure and self-capacity problems may have been less severe than what is typically found in clinical groups (Briere, 2000), the current study may underestimate phenomena (e.g., relational difficulties) and associations that are more visible in help-seeking individuals. On the other hand, use of a general population sample may have reduced the effects of unmonitored, yet potentially biasing variables (e.g., socioeconomic/demographic status) more relevant to clinical samples. Second, the relatively low return rate for this study increases the likelihood that the data reported here are not fully representative of the general population—instead merely constituting a relatively large sample of nonclinical individuals who were not selected on the basis of any specific dependent or independent variable. Third, the cross-sectional nature of this study means that the influence of certain potentially confounding variables cannot be entirely ruled out. For example, some abusive or neglectful behaviors may arise in the context of parental psychopathology that, in turn, may be genetically transmissible—potentially augmenting the correlation between abusive parental behavior and children's psychological symptoms. Finally, the retrospective self-report nature of this study introduces potential confounds associated with under- or overreporting of trauma exposure and/or symptomatology, although the anonymous nature of this survey is likely to have reduced any secondary gain for response distortion. In conclusion, the current results highlight the potential role of certain forms of childhood maltreatment in the development of identity disturbance, affect dysregulation, and relationship problems. Although subject to the interpretive constraints of any cross-sectional study, they especially suggest that maternal emotional abuse, paternal emotional nonsupport, and childhood sexual abuse are specific, independent risk factors for self-disturbance. These data join other recent studies (see reviews by Erickson and Egeland [2002] and Hart et al. [2002]) that highlight the probable negative impacts of emotional abuse and neglect above and beyond the more established detrimental effects of childhood sexual and physical maltreatment.
