A Concise Measure of Anger in Combat-Related Posttraumatic Stress Disorder

There is a need for a brief specific measure of anger for use in assessment of posttraumatic mental health problems. One unpublished short scale is the Dimensions of Anger Reactions (DAR; R. Novaco, 1975). This study examined the psychometric properties of the DAR using intake and 12-month data for 192 Australian Vietnam veterans with combat-related PTSD. Results showed the DAR to be unidimensional, reliable, and sensitive to change over time, and removal of two items improved the scale's properties. The DAR measures anger disposition directed towards others. Assessment of convergent validity indicated that the DAR primarily measures Trait Anger. Results suggest that the DAR is a psychometrically strong measure, potentially useful for the evaluation of anger in PTSD.     

Trauma‐Exposed Community‐Dwelling Women and Men Respond Similarly to the DAR‐5 Anger Scale: Factor Structure Invariance and Differential Item Functioning

Anger is associated with the development of posttraumatic stress disorder (PTSD) and with poor treatment outcomes. The Dimensions of Anger Reactions Scale‐5 (DAR‐5) has demonstrated preliminary evidence of unitary factor structure and sound psychometric properties. Gender‐based differences in psychometric properties have not been explored. The current study examined gender‐based factor structure invariance and differential item functioning of the DAR‐5 and gender differences in PTSD symptoms as a function of anger severity using a community sample of adults who had been exposed to trauma. Data were collected from 512 trauma‐exposed community‐dwelling adults (47.9% women). Confirmatory factor analyses, Mantel‐Haenszel χ² tests and a comparison of characteristic curves, and 2‐way analyses of variance, respectively, were used to assess gender‐based factor structure invariance, gender‐based response patterns to DAR‐5 items, and gender differences in PTSD symptoms as a function of anger. The unitary DAR‐5 factor structure did not differ between men and women. Significant gender differences in the response pattern to the DAR‐5 items were not present. Trauma‐exposed individuals with high anger reported greater overall PTSD symptoms (p < .001), regardless of gender. The DAR‐5 can be used to assess anger in trauma‐exposed individuals without concern of gender biases influencing factor structure or item functioning. Findings further suggested that the established relationship between anger and PTSD severity did not differ by gender.     

Trajectories of PTSD Among Lower Manhattan Residents and Area Workers Following the 2001 World Trade Center Disaster, 2003–2012

Group‐based trajectory modeling was used to explore empirical trajectories of symptoms of posttraumatic stress disorder (PTSD) among 17,062 adult area residents/workers (nonrescue/recovery workers) enrolled in the World Trade Center (WTC) Health Registry using 3 administrations of the PTSD Checklist (PCL) over 9 years of observation. Six trajectories described PTSD over time: low‐stable (48.9%), moderate‐stable (28.3%), moderate‐increasing (8.2%), high‐stable (6.0%), high‐decreasing (6.6 %), and very high‐stable (2.0%). To examine factors associated with improving or worsening PTSD symptoms, groups with similar intercepts, but different trajectories were compared using bivariate analyses and logistic regression. The adjusted odds of being in the moderate‐increasing relative to the moderate‐stable group were significantly greater among enrollees reporting low social integration (OR = 2.18), WTC exposures (range = 1.34 to 1.53), job loss related to the September 11, 2001 disaster (OR = 1.41), or unmet mental health need/treatment (OR = 4.37). The odds of being in the high‐stable relative to the high‐decreasing group were significantly greater among enrollees reporting low social integration (OR = 2.23), WTC exposures (range = 1.39 to 1.45), or unmet mental health need/treatment (OR = 3.42). The influence of severe exposures, scarce personal/financial resources, and treatment barriers on PTSD trajectories suggest a need for early and ongoing PTSD screening postdisaster.     

Social Information Processing in Anger Expression and Partner Violence in Returning U.S. Veterans

We examined social information processing factors that could represent pathways through which posttraumatic stress disorder (PTSD) symptoms relate to anger expression and intimate partner violence (IPV) perpetration in returning U.S. veterans. The sample included 92 male Operation Enduring Freedom/Operation Iraqi Freedom veterans, primarily Caucasian (77.4%), with smaller numbers of African American, Asian, Hispanic or Latino, American Indian or Alaskan Native, and other minority participants (9.7%, 2.2%, 2.2%, 3.2%, and 5.3% respectively). The average age was 40.37 (SD = 9.63) years. Data were collected through self‐report questionnaires (PTSD Checklist, State‐Trait Anger Expression Scale, Revised Conflict Tactics Scales) and the Articulated Thoughts in Simulated Situations experimental protocol. Laboratory‐based assessment of cognitive biases and hostile attributions were tested as mediators of associations between PTSD symptoms and anger expression and IPV. Among the PTSD symptom clusters, hyperarousal symptoms were most strongly associated with anger expression (r = .50) and IPV perpetration (r = .27). Cognitive biases mediated associations between PTSD total scores and 3 of 4 PTSD cluster scores as well as anger expression. Hostile attribution biases were also associated with IPV perpetration (r = .23). We discuss the implications of these findings for understanding social information processing mechanisms for the relationship between PTSD symptoms and aggression.     

Measuring Aggregated and Specific Combat Exposures: Associations Between Combat Exposure Measures and Posttraumatic Stress Disorder,Depression, and Alcohol‐Related Problems

Research has shown combat exposure to be associated with negative mental health outcomes. Different combat exposure measures are not composed of the same combat experiences, and few combat exposure measures have been directly compared to another measure. Furthermore, research about the unique associations between specific combat experiences and mental health is lacking. We investigated associations between new‐onset posttraumatic stress disorder (PTSD), new‐onset depression, and alcohol‐related problems and two commonly used measures of combat among a sample of 20,719 recently deployed U.S. military personnel. A 13‐item measure assessed both direct and indirect combat exposures, and a 5‐item measure assessed only indirect exposures. Both combat measures were associated with all outcomes in the same direction (e.g., PTSD, odds ratio [OR] = 2.97 vs. 4.01; depression, OR = 2.03 vs. 2.42; alcohol‐related problems, OR = 1.41 vs. 1.62, respectively, for the 5‐ and 13‐item measures). The 13‐item measure had a stronger association with some outcomes, particularly PTSD. Each specific item had significant bivariate associations with all outcomes, ORs = 1.43–4.92. After adjusting for other combat exposures, items assessing witnessing abuse, feeling in danger, and knowing someone injured or killed remained associated with all outcomes, ORs = 1.18–2.72. After this adjustment, several items had unexpected protective associations with some mental health outcomes. Results indicated these two combat exposure measures were approximately equally effective for determining risk for negative mental health outcomes in a deployed population, despite having different content. Additional research is needed to replicate and understand how specific combat exposures affect health.     

Differential Effects of Exposure to Social Violence and Natural Disaster on Children's Mental Health

Disaster mental health, particularly postdisaster child mental health, is neglected in India. This study compares the impact of a natural disaster versus a spate of communal riots that occurred in Gujarat, India on January 26, 2001, and February 2002 to June 2002, respectively. Children aged 8–15 years from highly exposed earthquake sites (n = 128) and riot sites (n = 171) were approached for participation. A matching control sample of 351 nontrauma‐exposed children was sought to compare with the trauma groups. Trauma and postdisaster adversities were studied using the UCLA disaster trauma tool; Goodman's Strengths and Difficulties Questionnaire was used to assess adjustment difficulties. Spearman's correlations were calculated to find associations between trauma items on UCLA's brief trauma scale and Strengths and Difficulties Questionnaire items. Results suggest that 7.6% of the earthquake sample and 38.7% from the riots sample manifested clinically significant mental health problems. The earthquake sample had 24.8% of those above clinical cutoff for probable posttraumatic stress disorder and the riots sample had 27.3% children who displayed posttraumatic stress symptoms. Children exposed to violence were psychologically more affected and in the presence of postdisaster adversities, posttraumatic stress symptoms persisted long term. This finding should enable development of differential psychotherapeutic interventions for children exposed to extreme events.     

Exposure to Violence During Ferguson Protests: Mental Health Effects for Law Enforcement and Community Members

There is little information available on the mental health effects of exposure to shared community violence such as the August 2014 violence that occurred in Ferguson, Missouri. This study sought to examine the relationship between proximity to community violence and mental health in both community members and police officers. We recruited 565 adults (community, n = 304, and police, n = 261) exposed to the violence in Ferguson to complete measures of proximity to violence, posttraumatic stress, depression, and anger. Using structural equation modeling, we assessed aspects of proximity to violence—connectedness, direct exposure, fear from exposure, media exposure, reactions to media, and life interruption—as correlates of posttraumatic stress disorder (PTSD) symptoms, depression, and anger. The final model yielded (n = 432), χ²(d = 12) = 7.4, p = .830; comparative fit index = 1.0, root mean square error of approximation = 0 [0, .04]. All aspects of proximity except direct exposure were associated with mental health outcomes. There was no moderation as a function of community versus police. Race moderated the relationship between life interruptions and negative outcomes; interruption was related to distress for White, but not Black community members. Based on group comparisons, community members reported more symptoms of PTSD and depression than law enforcement (η_p² = .06 and .02, respectively). Black community members reported more PTSD and depression than White community members (η_p² = .05 and .02, respectively). Overall, distress was high, and mental health interventions are likely indicated for some individuals exposed to the Ferguson events.     

Associations Between Motor Vehicle Crashes and Mental Health Problems: Data From the National Survey of Adolescents‐Replication

Motor vehicle crashes (MVCs) are a leading cause of physical injuries and mortality among children and adolescents in the United States. The purpose of this study was to examine associations between having an MVC and mental health outcomes, including posttraumatic stress disorder (PTSD), depression, and drug and alcohol misuse in a nationally representative sample of adolescents. A sample of 3,604 adolescents, aged 12–17 years, was assessed as part of the 2005 National Survey of Adolescents‐Replication (NSA‐R) study. Data were weighted according to the 2005 U.S. Census estimates. Within this sample, 10.2% of adolescents reported having at least 1 serious MVC. The prevalence of current PTSD and depression among adolescents having an MVC was 7.4% and 11.2%, respectively. Analyses revealed that an MVC among adolescents aged 15 years and younger was independently associated with depression (OR = 2.17) and alcohol abuse (OR = 2.36) after adjusting for other risk factors, including a history of interpersonal violence. Among adolescents aged 16 years and older, an MVC was associated only with alcohol abuse (OR = 2.08). This study was the first attempt to explore adverse mental health outcomes associated with MVCs beyond traumatic stress symptoms among adolescents in a nationally representative sample.     

Posttraumatic Stress Disorder and Barriers to Care in Eastern Cape Province,South Africa

A range of barriers to seeking mental health care in low‐ and middle‐income countries has been investigated. Little, however, is known of the barriers to care and help‐seeking behavior among people with posttraumatic stress disorder (PTSD) in low‐ and middle‐income countries. This was a population‐based study including 977 people aged 18–40 years from the Eastern Cape Province in South Africa. Current PTSD was assessed by using a diagnostic questionnaire (Mini International Psychiatric Interview). An additional questionnaire captured socioeconomic and health‐related data. The prevalence of current PTSD was 10.8%. Only 48.1% of people with current PTSD accessed health care services. Younger people aged 18 to 29 years were less likely to seek health care, OR = 0.36, 95% CI [0.15, 0.85]. People earning a salary or wage, OR = 2.91, 95% CI [1.26, 6.71]; and those with tuberculosis, OR = 11.63, 95% CI [1.42, 95.56], were more likely to seek health care. A range of barriers to seeking care were identified, the most striking being stigma and a lack of knowledge regarding the nature and treatment of mental illness. People with current PTSD may seek help for other health concerns and brief screening means those affected may be readily identified.     

Does Perpetrating Violence Damage Mental Health? Differences Between Forcibly Recruited and Voluntary Combatants in DR Congo

As a consequence of the ongoing conflict in the Democratic Republic of the Congo (DRC), combatants are constantly involved in various forms of violence. Findings concerning the impact of perpetrating violence on mental health are contradictory, ranging from increasing to buffering the risk for mental ill health. The present study investigated the impact of perpetrating violence on mental health. In total, 204 forcibly recruited and voluntary male combatants (mean age = 24.61 years) from different armed groups in the eastern DRC took part in the study. In a semistructured interview, respondents were questioned about appetitive aggression and posttraumatic stress disorder (PTSD) as well as self‐experienced violence and self‐perpetrated violent offending. A multivariate analysis of variance (η² = .23) revealed that voluntary combatants perpetrated more violent acts (η² = .06) and showed higher appetitive aggression η² = .03). A moderated multiple regression analysis (R² = .20) showed that perpetrating violence was positively related to PTSD in forcibly recruited combatants, but not in voluntary combatants. Thus, perpetrating violence may not necessarily qualify as a traumatic stressor. Further studies might consider assessing the combatant's perception of committing violent acts.     

The Hong Kong Survey on the Epidemiology of Trauma Exposure and Posttraumatic Stress Disorder

This study examined the epidemiology of trauma exposure (TE) and posttraumatic stress disorder (PTSD) among community‐dwelling Chinese adults in Hong Kong. Multistage stratification sampling design was used, and 5,377 participants were included. In Phase 1, TE, probable PTSD (p‐PTSD), and psychiatric comorbid conditions were examined. In Phase 2, the Structured Clinical Interview for the DSM‐IV (SCID‐I) was used to determine the weighted diagnostic prevalence of lifetime full PTSD. Disability level and health service utilization were studied. The findings showed that the weighted prevalence of TE was 64.8%, and increased to 88.7% when indirect TE types were included, with transportation accidents (50.8%) reported as the most common TE. The prevalence of current p‐PTSD among participants with TE was 2.9%. Results of logistic regression suggested that nine specific trauma types were significantly associated with p‐PTSD; among this group, severe human suffering, sexual assault, unwanted or uncomfortable sexual experience, captivity, and sudden and violent death carried the greatest risks for developing PTSD, odds ratio (OR) = 2.32–2.69. The occurrence of p‐PTSD was associated with more mental health burdens, including (a) sixfold higher rates for any past‐week common mental disorder, OR = 28.4, (b) more mental health service utilization, p < .001, (c) poorer mental health indexes in level of symptomatology, suicide ideation and functioning, p < .001, and (d) more disability, ps < .001–p = .014. The associations found among TE, PTSD, and health service utilization suggest that both TE and PTSD should be considered public health concerns.     

Predictors of Treatment Interest and Treatment Initiation in a VA Outpatient Trauma Services Program Providing Evidence‐Based Care

The present study explored interest in treatment and treatment initiation patterns among veterans presenting at a VA posttraumatic stress disorder (PTSD) clinic. U.S. veterans who were referred for treatment of posttraumatic stress symptoms (N = 476) attended a 2‐session psychoeducation and orientation class where they completed measures of demographic variables, PTSD and depression symptom severity, and interest in treatment. Consistent with previous literature and our hypotheses, Vietnam (OR = 1.78) and Persian Gulf veterans (OR = 2.05) were more likely than Iraq and Afghanistan veterans to initiate treatment. Veterans reporting more severe PTSD and depression symptoms were more likely to initiate treatment than not (OR for PTSD = 1.02, OR for depression = 1.02). Interest in treatment emerged as a strong predictor of treatment initiation. Specifically, interest in trauma‐focused treatment showed a significant independent predictive effect on initiation such that veterans who expressed interest in trauma‐focused treatment were significantly more likely to initiate treatment than those who did not express interest (OR = 2.13). Building interest in trauma‐focused treatment may be a vital component for engaging veterans in evidence‐based trauma‐focused therapy.     

Children's mental health care following Hurricane Katrina: A field trial of trauma‐focused psychotherapies

New Orleans school children participated in an assessment and field trial of two interventions 15 months after Hurricane Katrina. Children (N = 195) reported on hurricane exposure, lifetime trauma exposure, peer and parent support, posttraumatic stress disorder (PTSD), and depressive symptoms. Teachers reported on behavior. At baseline, 60.5% screened positive for PTSD symptoms and were offered a group intervention at school or individual treatment at a mental health clinic. Uptake of the mental health care was uneven across intervention groups, with 98% beginning the school intervention, compared to 37% beginning at the clinic. Both treatments led to significant symptom reduction of PTSD symptoms, but many still had elevated PTSD symptoms at posttreatment. Implications for future postdisaster mental health work are discussed.     

Prevalence of a Positive Screen for PTSD Among OEF/OIF and OEF/OIF‐Era Veterans in a Large Population‐Based Cohort

Multiple studies have reported the prevalence of posttraumatic stress disorder (PTSD) in Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) veterans; however, these studies have been limited to populations who use the Department of Veterans Affairs (VA) for health care, specialty clinic populations, or veterans who deployed. The 3 aims of this study were to report weighted prevalence estimates of a positive screen for PTSD among OEF/OIF and nondeployed veterans, demographic subgroups, and VA health care system users and nonusers. The study analyzed data from the National Health Study for a New Generation of U.S. Veterans, a large population‐based cohort of OEF/OIF and OEF/OIF‐era veterans. The overall weighted prevalence of a positive screen for PTSD in the study population was 13.5%: 15.8% among OEF/OIF veterans and 10.9% in nondeployed veterans. Among OEF/OIF veterans, there was increased risk of a positive screen for PTSD among VA health care users (OR = 2.71), African Americans (OR = 1.61), those who served in the Army (OR = 2.67), and those on active duty (OR = 1.69). The same trend with decreased magnitude was observed in nondeployed veterans. PTSD is a significant public health problem in OEF/OIF‐era veterans, and should not be considered an outcome solely related to deployment.     

PTSD Among Aboriginal and Torres Strait Islander People in Custody in Australia: Prevalence and Correlates

Mental disorder and trauma experiences are highly prevalent among individuals in custody; however, the impact of posttraumatic stress disorder (PTSD) on functioning is rarely considered. Indigenous Australians are incarcerated at 13 times the rate of nonindigenous Australians and report high levels of trauma exposure and psychological distress. In analysis of the largest systematic study of mental disorder among indigenous Australians in custody (N = 396), we found that the 12‐month prevalence of PTSD was high in both men (12.1%) and women (32.3%). Having PTSD was also associated with high rates of co‐occurring mental disorders (anxiety 31.2%, depression 32.8%, psychosis 24.6%, and substance use, 75.4%), lifetime suicidal ideation (50.1%), and suicide attempts (34.4%). Individuals with PTSD, compared to those without, were more likely to experience other mental disorders, OR = 2.42, 95% CI [1.12, 5.80], p = .022; lifetime suicide thoughts, OR = 2.43, 95% CI [1.34, 4.39], p = .001, and attempts, OR = 2.56, 95% CI [1.33, 4.83], p = .002; and high rates of intoxication at the time of arrest. Despite this, most (58.9%) had not accessed any form of mental health care prior to incarceration. These findings highlight the need to identify and manage PTSD in community and custodial populations.     

The Effect of Employment Status in Postdisaster Recovery: A Longitudinal Comparative Study Among Employed and Unemployed Affected Residents

Population studies have shown that employed adults are healthier than unemployed adults. In this study, we examined whether this “healthy worker effect” is relevant in postdisaster mental health by examining whether trauma‐exposed employed individuals have lower postdisaster initial mental health problems and/or whether they recover faster than trauma‐exposed unemployed individuals. We compared the course of postevent intrusion and avoidance reactions, anxiety, depression, and sleeping difficulties of employed residents (n = 291) and unemployed residents (n = 269) affected by a fireworks disaster in a residential area of Enschede, The Netherlands. Measurements took place at 2–3 weeks (T1), 18 months (T2), and 4 years (T3) postdisaster. We used linear mixed‐effect models to examine the course of mental health problems. Employment status was relevant, to a degree, in posttrauma recovery; although affected employed residents had significantly lower levels of mental health problems (initially and over time) than the unemployed, ds = 0.41–0.72, the recovery rate was the same for both groups. At T1 (neglecting the DSM 1‐month criterion), T2, and T3, the prevalence of probable posttraumatic stress disorder was 45.4%, 18.9%, and 11%, respectively, among employed individuals, and 70.1%, 32.5%, and 30% among unemployed individuals. We concluded that research into the mental health of disaster victims should take employment status into account. Regarding postdisaster care, unemployed individuals may need special attention; although they may recover at the same rate as employed individuals, they suffer from more severe mental health problems, even years after the disaster.     

Mental Health Following Separation in a Disaster: The Role of Attachment

Short‐term separation from close family members during a disaster is a highly salient event for those involved. Yet, its subsequent impact on mental health has received little empirical attention. One relevant factor may be attachment style, which influences patterns of support‐seeking under threatening conditions. Individuals (N = 914) affected by the 2009 Victorian bushfires in southeastern Australia were assessed for disaster experiences, depression, posttraumatic stress disorder (PTSD) symptoms, and attachment style 3–4 years after the fires. Using multigroup structural equation modelling, individuals who reported separation from close family members during the bushfires (n = 471) were compared to those who reported no separation (n = 443). Cross‐sectional results indicated that separated individuals had higher levels of PTSD symptoms. Furthermore, attachment anxiety was more strongly positively associated with depression among separated (b = 0.62) versus not separated individuals (b = 0.32). Unexpectedly, among separated individuals, attachment avoidance had a statistically weaker association with depression (b = 0.17 vs. b = 0.35) and with PTSD symptoms (b = 0.06 vs. b = 0.22). These results suggest that attachment anxiety amplifies a negative reaction to separation; meanwhile, for avoidant individuals, separation in times of danger may facilitate defensive cognitive processes.     

Using Interpretation Bias Modification to Reduce Anger in Veterans with Posttraumatic Stress Disorder: A Pilot Study

Difficulty controlling anger is the most commonly reported reintegration concern among veterans with posttraumatic stress disorder (PTSD). One of the mechanisms associated with problematic anger is a tendency to interpret ambiguous interpersonal situations as hostile, known as the hostile interpretation bias (HIB). A computer-based interpretation bias modification (IBM) intervention has been shown to successfully reduce HIB and anger but has not been tested in veterans with PTSD. The current study was a pilot trial of this IBM intervention modified to address problematic anger among veterans with PTSD. Veterans with PTSD and a high level of anger (N = 7) completed eight sessions of IBM treatment over the course of 4 weeks. Participants completed self-report questionnaires at pre- and posttreatment assessment visits, as well as a treatment acceptability interview at posttreatment. Veterans experienced large reductions in hostile interpretation bias and anger from pre- to posttreatment, ds = 1.03–1.96, although these estimates may be unstable due to the small sample size. The feasibility for recruitment, retention, and treatment completion were high. Questionnaire and interview data demonstrated that most participants were satisfied with the treatment and found it helpful and easy to use. Overall, IBM for anger was feasible and acceptable to veterans with PTSD and was associated with reductions in hostile interpretations and self-reported anger outcomes. Further research examining this approach is warranted.     

Unique PTSD Clusters Predict Intention to Seek Mental Health Care and Subsequent Utilization in US Veterans with PTSD Symptoms

Many veterans return from deployment with posttraumatic stress disorder (PTSD), but most attend only a limited number of mental health care visits. Although global PTSD relates to seeking mental health care, it is unclear whether specific features of PTSD inform the low rates of mental health care utilization. This study examined PTSD cluster severities of avoidance, reexperiencing, dysphoria, and hyperarousal as predictors of intention to seek mental health care and prospective treatment utilization. US veterans with at least subthreshold PTSD (N = 189) completed a PTSD symptom measure and indicated whether they intended to seek mental health care. Prospective Department of Veterans Affairs mental health care utilization was extracted from the medical record. At the bivariate level, each cluster was positively associated with a positive intention to seek mental health care and prospective treatment utilization. In multivariate models, however, dysphoria severity (OR = 1.16, 95% CI [1.06, 1.26]) was uniquely and positively correlated with intention to seek mental health care, whereas higher avoidance severity (IRR = 0.86, 95% CI [0.76, 0.98]) predicted lower treatment utilization, and higher reexperiencing severity (IRR = 1.07, 95% CI [1.01, 1.14]) predicted greater treatment utilization. It is critical to tailor interventions to target specific features of PTSD and to meet patients where they are.     

Treatment of Adolescent PTSD: The Impact of Prolonged Exposure Versus Client‐Centered Therapy on Co‐Occurring Emotional and Behavioral Problems

The present study evaluated secondary emotional and behavioral outcomes among adolescents who received prolonged exposure (PE‐A) or client‐centered therapy (CCT) for posttraumatic stress disorder (PTSD) in a randomized controlled trial. Participants were 61 adolescent girls (age: M = 15.33, SD = 1.50 years) with sexual abuse related PTSD seeking treatment at a community mental health clinic. Multilevel modeling was employed to evaluate group differences on the Youth Self‐Report (YSR) over acute treatment and 12‐month follow‐up. Both treatment groups showed significant improvements on all YSR scales from baseline to 12‐month follow‐up. Adolescents who received PE‐A showed significantly greater reductions than those receiving CCT on the Externalizing subscale (d = 0.70), rule‐breaking behavior (d = 0.63), aggressive behavior (d = 0.62), and conduct problems (d = 0.78). No treatment differences were found on the Internalizing subscale or among other YSR problem areas. Both PE‐A and CCT effectively reduced many co‐occurring problems among adolescents with PTSD. Although PE‐A focuses on PTSD and not on disruptive behaviors, PE‐A was associated with greater sustained changes in externalizing symptoms, supporting broad effects of trauma‐focused treatment on associated problem areas.
