We examined the frequency of trauma types reported in a cohort of service members seeking treatment for posttraumatic stress disorder (PTSD) and compared symptom profiles between types. In this observational study, 999 service members (9.2% women; M = 32.91 years; 55.6% White) were evaluated using a standardized assessment procedure to determine eligibility for clinical trials. Participants were evaluated for DSM-IV-TR-defined PTSD using the PTSD Symptom Scale-Interview; all participants reported a Criterion A event. Independent evaluators rated descriptions of Criterion A events as belonging to trauma types at a high degree of reliability, κ = 0.80. Aggregated non-life-threat primary trauma types were more frequently endorsed than aggregated life-threat types, 95% CI [17.10%, 29.20%]. Participants who endorsed moral injury-self traumas had a higher level of reexperiencing (d = 0.39), guilt (hindsight bias, d = 1.06; wrongdoing, d = 0.93), and self-blame (d = 0.58) symptoms, relative to those who reported life threat-self. Participants who experienced traumatic loss had greater reexperiencing (d = 0.39), avoidance (d = 0.22), guilt (responsibility, d = 0.39), and greater peri- and posttraumatic sadness (d = 0.84 and d = 0.70, respectively) symptoms, relative to those who endorsed life threat-self. Relative to life threat-self, moral injury-others was associated with greater peri- (d = 0.36) and posttraumatic (d = 0.33) betrayal/humiliation symptoms, and endorsement of aftermath of violence was associated with greater peri- (d = 0.84) and posttraumatic sadness (d = 0.57) symptoms. War zone traumas were heterogeneous, and non-life-threat traumas were associated with distinct symptoms and problems.

Evidence supports the prevalence of a high-trauma class experiencing poorer mental health, and the detrimental impact of aggregated interpersonal and other traumas. We highlight the clinical importance of addressing polytraumatization classes, and comprehensively assessing the impact of all traumas.

Existing literature indicates significant comorbidity between posttraumatic stress disorder (PTSD) and major depression. We examined whether PTSD's dysphoria and mood/cognitions factors, conceptualized by the empirically supported four-factor DSM-5 PTSD models, account for PTSD's inherent relationship with depression. We hypothesized that depression's somatic and non-somatic factors would be more related to PTSD's dysphoria and mood/cognitions factors than other PTSD model factors. Further, we hypothesized that PTSD's arousal would significantly mediate relations between PTSD's dysphoria and somatic/non-somatic depression. Using 181 trauma-exposed primary care patients, confirmatory factor analyses (CFA) indicated a well-fitting DSM-5 PTSD dysphoria model, DSM-5 numbing model and two-factor depression model. Both somatic and non-somatic depression factors were more related to PTSD's dysphoria and mood/cognitions factors than to re-experiencing and avoidance factors; non-somatic depression was more related to PTSD's dysphoria than PTSD's arousal factor. PTSD's arousal did not mediate the relationship between PTSD's dysphoria and somatic/non-somatic depression. Implications are discussed.

Objectives Emotion dysregulation is a transdiagnostic factor central to the etiology and treatment of various clinical difficulties. Yet, research in this area has focused almost exclusively on emotion dysregulation stemming from negative emotions. The current study confirmed the factor structure of the Difficulties in Emotion Regulation Scale‐Positive (DERS‐P) and further examined its reliability and validity. Method Participants in Study 1 were 229 college students (M age = 19.37 years; 66.8% female; 67.2% White). Participants in Study 2 were 353 trauma‐exposed community individuals ( M age = 35.77 years; 57.8% female; 71.2% White). Results Findings supported the three‐factor structure of the DERS‐P. Mean levels of the DERS‐P scales demonstrated convergent and discriminant validity and differentiated individuals with (vs. without) probable posttraumatic stress disorder, depression, alcohol use, and drug use disorders. Conclusions Findings provide additional support for the factor structure, reliability, and validity of the DERS‐P, thereby adding to its clinical utility.
