The Influence of Premigration Trauma Exposure and Early Postmigration Stressors on Changes in Mental Health Over Time Among Refugees in Australia

As a result of the precarious conditions in which they migrate, refugees are likely to have experiences that increase their risk of mental health problems. Refugees tend to be predisposed to relatively high levels of distress upon resettlement, and a key predictor of these issues is traumatic experiences that occur before their arrival. Despite high initial levels of ill-health, on average, refugees tend to experience mental health recovery over time. However, both levels of mental health upon settlement and recovery over time may be negatively influenced by stressors in the postsettlement period. The present study examined changes in psychological distress and posttraumatic stress symptoms over 5 years among 2,169 refugees from various backgrounds, predominately from Iraq and Afghanistan, who participated in the Building a New Life in Australia (BNLA) study. A multivariate latent growth curve model found mental ill-health decreased on average, β = −.21 for distress and β ₌ −.31 for PTSD, ps < .001, and premigration trauma exposure predicted more initial PTSD symptoms and reduced recovery over time, β_Intercept = .21, β_Slope = −.54, p < .001. Postmigration stressors, such as loneliness, financial concerns, and cultural integration, predicted higher levels of mental health problems as well as reduced recovery over time. These findings suggest that beyond trauma exposure, the mental health of refugees upon resettlement and their recovery over time is impacted by stressors in the early resettlement period, which has important implications for interventions and services to support and encourage well-being in refugee populations.     

Cortisol and PTSD Symptoms Among Male and Female High‐Exposure 9/11 Survivors

Only a few studies have examined cortisol response to trauma‐related stressors in relation to posttraumatic stress disorder (PTSD). We followed a sample of high‐exposure survivors of the attacks on September 11, 2001 (9/11; 32 men and 29 women) and examined their cortisol response after recalling the escape from the attack, 7 and 18 months post‐9/11. PTSD symptoms and saliva cortisol levels were assessed before and after trauma recollection. Hierarchical regression analyses revealed that PTSD symptoms and male sex predicted increased cortisol response following recollections. For men, elevated cortisol was associated with greater severity of reexperiencing symptoms (p < .001) and lower severity of avoidance symptoms (p < .001). For women, recall‐induced cortisol was minimal and unrelated to PTSD symptoms (p = .164 and p = .331, respectively). These findings suggest that augmented cortisol response to trauma‐related stressors may be evident in men reporting symptoms of PTSD. Thus, as cortisol abnormalities related to PTSD symptoms appear sex‐specific, future research on mechanisms of sex differences in response to trauma is warranted.     

Changes in Trauma‐Related Emotions Following Treatment With Dialectical Behavior Therapy for Posttraumatic Stress Disorder After Childhood Abuse

Dialectical behavior therapy for posttraumatic stress disorder (DBT‐PTSD) is a trauma‐focused therapy shown to reduce core PTSD symptoms, such as intrusions, hyperarousal, and avoidance. Preliminary data indicate effects on elevated trauma‐related emotions (e.g., guilt and shame) and possibly radical acceptance of the traumatic event. However, it is unclear if improvements in these variables are significant after controlling for changes in core PTSD symptoms and to what extent nonclinical levels are obtained. In the current study, 42 individuals who met criteria for PTSD after childhood abuse and were participating in a 3‐month residential DBT‐PTSD program were evaluated at the start of the exposure phase of DBT‐PTSD and the end of treatment; a nonclinical sample with a history of childhood abuse was the reference group. Multivariate analyses of variance and multivariate analyses of covariance controlling for change in core PTSD symptoms were used to evaluate changes in several elevated trauma‐related emotions (fear, anger, guilt, shame, disgust, sadness, and helplessness) and in radical acceptance. In a repeated measures multivariate analyses of variance, both elevated trauma‐related emotions and radical acceptance significantly improved during DBT‐PTSD, λ = 0.34, p < .001; η² = .56; t(40) = ?5.66, p < .001, SMD = 0.88, even after controlling for changes in PTSD symptoms, λ = 0.35, p < .001, η² = .65; Λ = 0.86, p = .018, η² = .14, respectively. Posttreatment, 31.0% (for acceptance) to 76.2% (for guilt) of participants showed nonclinical levels of the investigated outcomes, suggesting that both trauma‐related emotions and radical acceptance changed after the 3‐month residential DBT‐PTSD program.     

Examining the Discriminant Validity of Complex Posttraumatic Stress Disorder and Borderline Personality Disorder Symptoms: Results From a United Kingdom Population Sample

Complex posttraumatic stress disorder (CPTSD) was added to the diagnostic nomenclature in the 11th revision of the International Classification of Diseases (ICD‐11). Although considerable evidence exists supporting the construct validity of CPTSD, the distinguishability of CPTSD symptoms from those of borderline personality disorder (BPD) has been questioned. The present study examined the discriminant validity of CPTSD and BPD symptoms among a trauma‐exposed population sample from the United Kingdom (N = 546). Participants completed self‐report measures of CPTSD and BPD symptoms, and their latent structure was assessed using exploratory structural equation modeling (ESEM). A three‐factor model with latent variables reflecting PTSD, disturbances in self‐organization (DSO), and BPD symptoms provided the best fit of the data, χ²(399, N = 546) = 1,650, p < .001; CFI = .944; TLI = .930; RMSEA = .077, 90% CI [.073, .081]. We identified multiple symptoms distinctive to individual constructs (e.g., disturbed relationships and suicidality) as well as symptoms shared across the constructs (e.g., affective dysregulation). The PTSD, β = .24; DSO, β = .23; and BPD, β = .27, latent variables were positively and significantly associated with childhood interpersonal trauma. The current findings support the discriminant validity of CPTSD and BPD symptoms and highlight various phenomenological signatures of each construct as well as demonstrate how these constructs share important similarities in symptom composition and exogenous correlates.     

Associations Between Functioning and PTSD Symptom Clusters in a Dismantling Trial of Cognitive Processing Therapy in Female Interpersonal Violence Survivors

This study conducted secondary analyses of a published trial and sought to determine if different domains of psychosocial functioning (e.g., daily living, work, nonfamily relationships) improved following trauma‐focused treatment for posttraumatic stress disorder (PTSD). Cognitive processing therapy (CPT), an empirically supported treatment that involves evaluating trauma‐related beliefs and written trauma accounts, was compared to its components: CPT without the written accounts or written accounts only in a sample of 78 women with PTSD secondary to interpersonal violence. Overall and individual domains of functioning significantly improved with treatment and results were similar across treatment groups, Fs (2, 150) ≥ 11.87, ps < .001. Additionally, we investigated whether changes in different PTSD symptom clusters were associated with outcomes in domains of psychosocial functioning, after collapsing across treatment condition. Multiple hierarchical linear regression analyses revealed that overall clinician‐assessed PTSD symptom reduction was associated with outcomes in all domains of functioning, βs = .44 to .68, ps < .001. Additionally, improvements in the emotional numbing symptom cluster were associated with outcomes in the nonfamily relationships domain, β = .42, p < .001, and improvements in the hyperarousal symptom cluster were associated with outcomes in the overall, daily living, and household tasks domains, βs = .34 to .39, ps < .01. Results suggest that it may be important to monitor improvements in emotional numbing and hyperarousal symptoms throughout treatment to increase the likelihood of changes in psychosocial functioning.     

Physical Injury,PTSD Symptoms,and Medication Use: Examination in Two Trauma Types

Physical injury is prevalent across many types of trauma experiences and can be associated with posttraumatic stress disorder (PTSD) symptoms and physical health effects, including increased medication use. Recent studies suggest that PTSD symptoms may mediate the effects of traumatic injury on health outcomes, but it is unknown whether this finding holds for survivors of different types of traumas. The current study examined cross‐sectional relationships between injury, PTSD, and pain and psychiatric medication use in 2 trauma‐exposed samples, female survivors of motor vehicle accidents (MVAs; n = 315) and intimate partner violence (IPV; n = 167). Data were obtained from participants at 2 trauma research clinics who underwent a comprehensive assessment of psychopathology following the stressor. Regression with bootstrapping suggested that PTSD symptoms mediate the relationship between injury severity and use of pain medications, R² = .11, F(2, 452) = 28.37, p < .001, and psychiatric medications, R² = .06, F(2, 452) = 13.18, p < .001, as hypothesized. Mediation, however, was not moderated by trauma type (ps > .05). Results confirm an association between posttraumatic psychopathology and medication usage and suggest that MVA and IPV survivors alike may benefit from assessment and treatment of emotional distress after physical injury.     

The Association Between Posttraumatic Negative Self‐Conscious Cognitions and Emotions and Maladaptive Behaviors: Does Time Since Trauma Exposure Matter?

Negative beliefs about the self, self‐blame, guilt, and shame have been consistently linked to emotional problems, such as posttraumatic stress disorder and depression, following trauma exposure. To expand understanding of the potential role of negative self‐conscious cognitions and emotions in other forms of posttrauma maladjustments, such as maladaptive behaviors, the current study examined the associations between these cognitions and emotions with dissociation, alcohol use, and avoidant problem‐solving. As a secondary goal, the influence of time since trauma exposure was considered given recent data suggesting that some posttraumatic responses require lengthier time following trauma to become salient. Multiple‐group analysis was conducted in two groups of female survivors of intimate partner violence (IPV): women whose IPV experiences occurred within 3 months prior to assessment (early posttrauma phase [EPP]; n = 67) and those whose experiences occurred 12 months or more prior to assessment (chronic posttrauma phase [CPP]; n = 145). The results suggested model invariance. Posttraumatic negative self‐conscious cognitions and emotions were significantly correlated with dissociation (EPP group: β = .61, p < .001 and CPP group: β = .48, p < .001), alcohol use (EPP group: β = .31, p = .014 and CPP group: β = .30, p < .001), and avoidant problem‐solving (EPP group: β = .58, p < .001 and CPP group: β = .56, p < .001). The findings highlight the importance of negative self‐conscious cognitions and emotions in posttrauma maladjustment and support intervening in these domains shortly after trauma exposure.     

Investigating the effects of suicide exposure among a clinical sample of active duty service members

Suicide exposure warrants further investigation as a risk factor for suicide among military service members. This study aimed to examine associations among suicide exposure, suicidal ideation (SI), and psychological symptoms in a clinical sample of service members (N = 1,565, 64.4% suicide-exposed) and identify how one's relationship with the deceased impacts suicidality and psychological health in exposed individuals. A secondary analysis of cross-sectional survey data was conducted. Generalized linear regression analyses were used to identify associations between suicide exposure and both current SI and psychological symptoms among all participants; the associations between suicide exposure characteristics and psychological symptoms were only examined among exposed individuals. Exposure was not significantly associated with higher SI, β = .007, SE = .16, p = .965, but was associated with PTSD, β = 1.60, SE = 0.49, p = .001; anxiety, β = .68, SE = .31, p = .031; and insomnia symptoms, β = .98, SE = .25, p < .001. Among participants who had been exposed, high/long impact of exposure was positively associated with SI, β = 0.94, SE = .26, p < .001, and psychological symptoms, PTSD: β = 2.32, SE = .77, p = .002; anxiety: β = 1.39, SE = .50, p = .005; insomnia: β = .96, SE = .39, p = .015. Results illustrate the significant issue of suicide exposure within the military and show consideration of suicide exposure as a potential risk factor for adverse psychological outcomes is warranted.     

The Cycle of Violence: Associations Between Exposure to Violence,Trauma‐Related Symptoms and Aggression—Findings from Congolese Refugees in Uganda

War‐related trauma exposure has been linked to aggression and enhanced levels of community and family violence, suggesting a cycle of violence. Reactive aggression—an aggressive reaction to a perceived threat—has been associated with posttraumatic stress disorder (PTSD). In contrast, appetitive aggression—a hedonic, intrinsically motivated form of aggression—seems to be negatively related to PTSD in offender and military populations. This study examined the associations between exposure to violence, trauma‐related symptoms and aggression in a civilian population. In semistructured interviews, 290 Congolese refugees were questioned about trauma exposure, PTSD symptoms, and aggression. War‐related trauma exposure correlated positively with exposure to family and community violence in the past month (r = .31, p < .001), and appetitive (r = .18, p = .002) and reactive aggression (r = .29, p < .001). The relationship between war‐related trauma exposure and reactive aggressive behavior was mediated by PTSD symptoms and appetitive aggression. In a multiple sequential regression analysis, trauma exposure (β = .43, p < .001) and reactive aggression (β = .36, p < .001) were positively associated with PTSD symptoms, whereas appetitive aggression was negatively associated (β = ?.13, p = .007) with PTSD symptoms. Our findings were congruent with the cycle of violence hypothesis and indicate a differential relation between distinct subtypes of aggression and PTSD.     

The role of time since trauma on treatment outcomes of veterans in two intensive posttraumatic stress disorder treatment programs

Research on the impact of time since trauma (TST) on posttraumatic stress disorder (PTSD) treatment outcomes lacks consensus and has not been examined in cognitive processing therapy (CPT)–based intensive PTSD treatment programs (ITPs). Furthermore, little is known about how TST impacts other trauma-related outcomes, such as depressive symptoms and negative posttrauma cognitions. We examined whether TST predicted severity and changes in PTSD and depressive symptoms and negative posttrauma cognitions, controlling for trauma type (combat or military sexual trauma), age, sex, and race, in two separate samples of veterans with PTSD who completed 2-week (n = 132) or 3-week (n = 407) CPT-based ITPs. In the 3-week sample, PTSD symptom reduction differed based on TST; however, these differences lacked clinical significance, TST x Time R²_b = .002, and were not replicated in the 2-week sample, R²_b < .001. TST did not significantly predict depressive symptoms, R²_b = .005, or negative posttrauma cognition severity or changes, R²_b = .002, in the 3-week sample. In the 2-week sample, linear mixed-effects models indicated that TST also did not significantly predict PTSD or depressive symptoms, R²_bs < .001, or negative posttrauma cognition severity or changes, R²_bs = .002. These findings suggest that TST is not a clinically relevant predictor of PTSD symptoms, depressive symptoms, or negative posttrauma cognitions among individuals engaged in CPT-based ITPs. Future research should investigate the association between TST and trauma-related outcomes in more trauma type– and age-diverse samples within different intensive treatment settings.     

Gender differences in mental health outcomes among Afghanistan veterans exposed to war zone trauma

Research has sought to identify whether women have an increased risk of developing mental health problems following military trauma compared to men, but the results are mixed. This study examined gender differences in a range of mental health outcomes within three levels of war zone trauma exposure and investigated gender differences in risk and protective factors associated with clinical mental health problems. Using data from a cross-sectional, postdeployment survey, a sample of Norwegian veterans of recent military operations in Afghanistan (N = 6,205, 8.3% women) were sorted according to reported war zone trauma exposure level (low, medium, high), then assessed for symptoms of posttraumatic stress disorder (PTSD), posttraumatic distress, anxiety, depression, insomnia, and alcohol problems. The findings revealed that men who reported low war zone exposure had lower levels of posttraumatic distress symptoms than women, d = -0.20, p = .040, but were more likely to report symptoms of alcohol problems within the low, d = 0.33, p < .001; medium, d = 0.39, p < .001; and high, d = 0.37, p = .049, exposure groups; however, these differences disappeared when all symptom variables were combined into one clinical mental health problem variable. Women with a clinical mental health problem were less likely to report war zone exposure than men, OR = 0.93, 95% CI [0.90, 0.97], p = .001. Findings suggest that although gender differences in mental health symptoms exist, male and female veterans with mental health problems may share more similarities than previously recognized.     

Cumulative Trauma Exposure,Emotion Regulation,and Posttraumatic Stress Disorder Among Incarcerated Women

Incarcerated women report high rates of trauma exposure and posttraumatic stress disorder (PTSD). Emotion regulation has been identified as a potential mechanism that contributes to the association between trauma exposure and PTSD severity. The present study examined associations among cumulative trauma exposure, emotion regulation difficulties, and current (30‐day) PTSD in 152 randomly selected women in prison. Utilizing structural equation modeling (SEM), results indicated cumulative trauma was significantly associated with emotion regulation difficulties, β = .31, SE = .13, p  = .005; and PTSD symptom severity, β = .41, SE = .14, p  = .005. We identified a significant indirect effect, 0.11, z = 2.37, p = .018, of emotion regulation on the association between cumulative trauma exposure and severity of current PTSD symptoms. These findings are consistent with previous longitudinal research suggesting that emotion regulation is significantly affected by trauma exposure, and they support previously identified associations between emotion regulation difficulties and severity of PTSD. Further, these findings have the potential to inform current efforts to identify and implement effective PTSD‐focused interventions with incarcerated women. In particular, it appears that emotion regulation skills may be an important component of effective PTSD focused interventions for this population.     

Patterns of Treatment Disengagement and Personality Traits Associated With Posttraumatic Stress Disorder in Recent‐Era U.S. Veterans Receiving Cognitive Processing Therapy

Low treatment engagement is a barrier to implementation of empirically supported treatments for posttraumatic stress disorder (PTSD) among veterans. Understanding personality traits that predict dropout may help focus attempts to improve engagement. The current study included 90 veterans who served in recent conflicts in Iraq and/or Afghanistan and participated in a trial of cognitive processing therapy for PTSD. Goals were to characterize (a) personality correlates of PTSD, (b) patterns of engagement (i.e., attendance and homework completion), and (c) personality correlates of reduced engagement. Higher levels of PTSD symptoms were associated with a range of characteristics, including affective lability, r = .44 p < .001; anxiety, r = .38, p < .001; identity problems, r = .57, p < .001; intimacy problems, r = .34, p = .001; low affiliation, r = .33, p = .002; oppositionality, r = .36, p = .001; restricted expression, r = .35, p = .001; and suspiciousness, r = .50, p < .001. Notably, veterans with worse PTSD symptoms endorsed more cognitive dysregulation, r = .40, p < .001; and less insecure attachment, r = .14, p = .190, than expected. Only 52.2% of veterans completed the 12‐session course of treatment and 31.0% of participants completed fewer than six sessions. Personality traits did not predict attendance or homework completion. Disengagement continues to be a significant issue in trauma‐focused treatment for veterans with PTSD. Understanding veteran‐level factors, such as personality traits, may be useful considerations for future research seeking to understand and improve engagement.     

Family Functioning and Mental Health in Runaway Youth: Association With Posttraumatic Stress Symptoms

This study examined the direct effects of physical and sexual abuse, neglect, poor family communication and worries concerning family relationships, depression, anxiety, and dissociation on posttraumatic stress symptoms. Runaway youth were recruited from emergency youth shelters in New York and Texas. Interviews were completed with 350 youth who averaged 15 years of age. Structural equation modeling was used to examine family functioning, maltreatment, depression, dissociation, and anxiety in relation to posttraumatic stress symptoms. Results indicated that direct effects of family relationship worry to dissociation, β = .77, p < .001; depression, β = .85, p < .001; and anxiety, β = .90, p < .001 were significant, as were relationships between family communication and youth dissociation, β = .42, p < .001; depression, β = .46, p < .001; and anxiety, β = .32, p < .001. No significant effects of physical/sexual abuse or neglect were found. Higher levels of dissociation, β = .21, p < .001 and anxiety symptoms, β = .34, p = .01 were positively and significantly associated with posttraumatic stress symptoms, but depression was not. Findings underscore the critical role of family relationships in mental health symptoms experienced by runaway adolescents.     

Social interactions in trauma disclosure: A multi-informant and multiconstruct investigation

Research has established that social factors are integral to trauma recovery. Yet, there is relatively little data on the association between social interactions from different supports and posttraumatic stress disorder (PTSD) symptoms. Moreover, few studies have measured these factors from multiple informants. This paper examined social interactions from different sources (i.e., negative and positive reactions from a chosen close other [CO], family/friends, and general non-COs) and their association with PTSD symptoms using multi-informant reports of the social constructs (i.e., from the individual exposed to trauma [TI] and their CO). Participants (N = 104 dyads) were recruited from an urban center within 6 months of the TIs’ exposure to a traumatic event. TIs were assessed using the Clinician-Administered PTSD Scale. TI self-report, t(97) = 2.58, p = .012, and CO collateral report of disapproval from family/friends, t(97) = 2.14, p = .035, and TI self-report of general disapproval, t(97) = 4.91, p < .001, emerged as significant predictors of PTSD symptoms when compared with other social constructs. Interventions that target family members’ and friends’ reactions to trauma survivors and societal discourse around trauma and reactions to trauma survivors are recommended. Clinical interventions that buffer against TIs’ experiences of disapproval and guide COs on the provision of supportive responses are discussed.     

Negative Cognitions Prior to Trauma Predict Acute Posttraumatic Stress Disorder Symptomatology

Based on emotional processing theory, preexisting negative cognitions may contribute to the development of posttraumatic stress disorder (PTSD) symptoms. The present study prospectively examined the association between preexisting PTSD‐related cognitions and subsequent acute PTSD symptoms, and the potential mediators of this association. We also compared the effect of preexisting depressive cognitions and preexisting PTSD‐related cognitions on PTSD symptoms. In the current study, 810 Taiwanese undergraduates completed a baseline survey (T1), of which 73.1% (n = 592) participated in a second survey two months later (T2). Of those who completed both surveys, 97 experienced a trauma at least one week before T2; this group comprised the final sample. Hierarchical regression showed that preexisting PTSD‐related cognitions (β = .38, p < .001, sr² = .117), but not preexisting depressive cognitions (β = .11, p = .315, sr² = .011), were a significant and substantial predictor of acute PTSD symptoms after we controlled for established pretrauma risk factors (i.e., gender, prior trauma, and prior psychological problems). Multiple mediation analysis revealed that negative appraisal of symptoms (a₁b₁ = 0.90, 95% CI [0.16, 2.18], P_M = .251) and trauma‐related rumination (a₃b₃ = 1.23, 95% CI [0.23, 2.86], P_M = .341), but not trauma memory disorganization (a₂b₂ = 0.65, 95% CI [?0.17, 1.92], P_M = .182), significantly mediated between preexisting PTSD‐related cognitions and acute PTSD symptoms. Our findings highlight the role of preexisting negative cognitions in acute PTSD symptomatology. The development of PTSD symptoms is likely determined by the interaction of risk factors before and after trauma.     

Coping Self‐Efficacy Moderates the Association Between Severity of Partner Violence and PTSD Symptoms Among Incarcerated Women

Previous research indicates self‐efficacy may function as a protective factor for survivors of partner violence (PV), including coping self‐efficacy specific to domestic violence. We hypothesized that domestic violence coping self‐efficacy would moderate the association between recent PV and posttraumatic stress disorder (PTSD) symptoms in a sample of incarcerated women, such that the association between PV and PTSD would be strongest at low levels of domestic violence coping self‐efficacy. Participants (N = 102) were incarcerated women who reported PV in the year prior to incarceration. They were aged 19–55 years (M = 33.57, SD = 9.32), identified predominantly as European American (84.3%), American Indian (15.7%), and Hispanic (14.7%), with 80.4% completing high school or more in terms of education. Participants responded to self‐report measures of PV, trauma history, domestic violence coping self‐efficacy, and current PTSD symptoms. In a series of sequential regression analyses, PV (β = .65, sr² = .06, p = .017) was significantly associated with current PTSD symptoms above and beyond past trauma history (β = .37, sr² = .14, p < .001), and this association was moderated by domestic violence coping self‐efficacy (Domestic Violence Coping Self‐Efficacy × Partner Violence; β = ?.54, sr² = .03, p = .044). The relationship between PV and PTSD symptoms was greatest at low and average levels of domestic violence coping self‐efficacy and nonsignificant at high levels of domestic violence coping self‐efficacy. These findings highlight the importance of assessing domestic violence coping self‐efficacy in incarcerated women with recent PV, given that domestic violence coping self‐efficacy appeared to be protective against symptoms of PTSD.     

Validation of the Fear of Sleep Inventory (FOSI) in an Urban Young Adult African American Sample

The Fear of Sleep Inventory (FOSI) was developed to identify factors that contribute to sleep disturbances in individuals exposed to trauma. This investigation examined the psychometric properties of the FOSI in a sample of African American young adults residing in urban areas. A 5‐factor structure was derived from an exploratory factor analysis and then verified by confirmatory factor analysis. FOSI factors were positively correlated with the severity of PTSD (rs = .30 to .58, all ps < .001) and insomnia symptoms (rs = .36 to .64, all ps < .001). Individuals with probable PTSD or insomnia had higher scores on the total FOSI and each of the factors compared to those without probable PTSD (all ps < .001; effect sizes: r = .32 to .62) or insomnia (all ps < .001; effect sizes: r = .42 to .70). These data expand the evidence that the FOSI identifies factors contributing to sleep disturbances in trauma‐exposed individuals.     

Military and Premilitary Trauma,Attachment Orientations,and Posttraumatic Stress Disorder Severity Among Male and Female Veterans

Samples in prior studies examining attachment theory in the military have been predominantly composed of male combat veterans. Given the rates of sexual trauma among female veterans and differences in the association between attachment and posttraumatic stress disorder (PTSD) severity for sexual trauma survivors, it was necessary to consider the attachment characteristics of veterans within a mixed‐sex sample. Participants were a mixed‐sex veteran sample seeking inpatient trauma‐related treatment (N = 469). Using independent samples t tests, we examined sex differences in attachment. Consistent with our hypothesis, women reported a higher level of attachment anxiety than did men, t(351) = ?2.12, p = .034. Women also reported a higher level of attachment avoidance, t(351) = ?2.44, p = .015. Using hierarchical regression, we examined the contribution of attachment anxiety and avoidance to PTSD severity, partialing out variance accounted for by demographic variables and traumatic experiences. Consistent with our hypotheses, attachment avoidance predicted PTSD severity on the Clinician‐Administered PTSD Scale for DSM‐IV (CAPS), β = .20, p < .001, and the PTSD Checklist–Civilian Version (PCL‐C), β = .18, p < .001. Attachment anxiety did not predict CAPS severity but did predict PCL‐C severity, β = .11, p = .020. These results suggest the association between attachment avoidance and PTSD is not exclusive to combat trauma and may apply more generally to the larger veteran population. Higher levels of attachment anxiety and avoidance among female veterans potentially implicate the presence of greater attachment fearfulness among this particular subpopulation of veterans.     

Traumatic Event Exposure,Posttraumatic Stress Disorder,and Sleep Disturbances in a National Sample of U.S. Adults

Posttraumatic stress disorder (PTSD) is a highly prevalent, debilitating disorder found to develop after exposure to a potentially traumatic event (PTE). Individuals with PTSD often report sleep disturbances, specifically nightmares and insomnia, which are listed within the criteria for PTSD. This research examined prevalence of insomnia and nightmares within a national sample of 2,647 adults (data weighted by age and sex to correct for differences in sample distribution) who had been exposed to one or more PTEs. Prevalence of self‐reported sleep disturbance, sleep disturbances by PTE type, and gender differences were examined. All participants completed a self‐administered, structured online interview that assessed exposure to stressful events and PTSD symptoms. Among individuals who met DSM‐5 criteria for PTSD, a large majority (more than 92%) reported at least one sleep disturbance. Insomnia was relatively more prevalent than PTE‐related nightmares among individuals with PTSD and among all PTE‐exposed individuals. A higher number of PTEs experienced significantly increased the likelihood of both trauma‐related nightmares and insomnia, McFadden's pseudo R² = .07, p < .001. Women exposed to PTEs were more likely to endorse experience of insomnia, χ²(1, N = 2,647) = 99.13, p < .001, φ = .194, and nightmares compared to men, χ²(1, N = 2,648) = 82.98, p < .001, φ = .177, but this gender difference was not significant among individuals with PTSD, ps = .130 and .050, respectively. Differences in sleep disturbance prevalence by PTE type were also examined. Implications for treatment and intervention and future directions are discussed.
