Research has demonstrated that youth who are sexually or physically abused are at greater risk for developing depression. Although the association between depression and child maltreatment has been well documented, much less is known about the potential differences in the clinical presentation of depressive symptomatology among these victims. The current study examines differences in symptoms of depression in adolescents based on differing histories of abuse (i.e., sexual abuse only, physical abuse only, sexual and physical abuse, and no history of sexual or physical abuse), abuse incident characteristics, and gender. Participants were drawn from a subsample (n = 548) from the National Survey of Adolescents who met criteria for major depressive episode in the past year. Results indicate significant differences in severity of depression and specific depressive symptoms based on type of abuse experienced and gender. Implications for the clinical assessment and treatment of depressed adolescents with regard to abuse history are discussed.

Introduction: A strong association between posttraumatic stress disorder (PTSD) and problematic alcohol use has been demonstrated among Veteran populations exposed to combat trauma. Several traits, such as higher levels of risk-taking propensity (RTP) and impulsivity (e.g., negative urgency [NU]), are associated with both increased PTSD symptomatology and greater alcohol use problems. Methods: The present study examined the effects of NU and RTP on alcohol use (measured by average weekly alcohol consumption and number of binge drinking days in 1 month), as well as their potential moderating effects on the association between PTSD symptom severity and alcohol use in a sample of Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn (OEF/OIF/OND) US Veterans. We hypothesized that NU and RTP would both significantly predict alcohol use and moderate the relation between PTSD symptom severity and alcohol use, such that the association between PTSD symptoms and alcohol use would be greater among individuals high compared to low in NU and RTP. Results: As hypothesized, the main effects of RTP and NU were significantly positively associated with average weekly alcohol consumption and the number of binge drinking days in the past month. However, neither NU nor RTP moderated the relation between PTSD and either alcohol variable. Discussion: NU and RTP may represent transdiagnostic risk markers for PTSD and alcohol use problems; however, the current study did not support an exploratory role of NU or RTP in the association between PTSD and alcohol use phenotypes.

Individual differences in cognitive processes and coping behaviors play a role in the development and maintenance of posttraumatic stress disorder (PTSD). Given the large numbers of combat-exposed service members returning from the Operation Enduring Freedom (OEF), Operation Iraqi Freedom (OIF), and Operation New Dawn (OND) conflicts, exploring individual differences in cognitive-affective processes is important for informing our understanding of PTSD etiology and early intervention in military samples. The present study examined the unique main and interactive effects of negative posttrauma cognitions (i.e., negative beliefs about self [NS], the world [NW], and self-blame [SB]) and coping strategies (i.e., positive behavioral, positive cognitive, avoidant coping, and social and emotional coping) on PTSD diagnosis within 155 (M(age) = 30.7, SD = 4.48) OEF/OIF/OND combat trauma-exposed veterans recruited from an ongoing study examining the effects of combat trauma and stress reactivity. In the final, stepwise logistic regression analysis, avoidant coping, but no other coping strategy, was significantly positively related to PTSD diagnosis in the initial step. Higher levels of NS, but not NW, were significantly associated with having a PTSD diagnosis, while SB was associated with decreased likelihood of PTSD, above and beyond coping strategies. A significant interaction effect was found between NS and positive cognitive coping, such that greater positive cognitive coping weakened the relationship between NS and PTSD. Examining and addressing coping behaviors and negative thoughts of self jointly may benefit assessment and intervention approaches in a combat-trauma population.
