Item Reckless Self-destructive Behavior and PTSD in Veterans: The Mediating Role of New Adverse Events(Wiley-Blackwell, 2017-06-23) Lusk, Joanna D.; Sadeh, Naomi; Wolf, Erika J.; Miller, Mark W.; Joanna D. Lusk, B.A., Naomi Sadeh, Ph.D., Erika J. Wolf, Ph.D., & Mark W. Miller, Ph.D.; Sadeh, NaomiThe addition of self-destructive and reckless behavior as a symptom of posttraumatic stress disorder (PTSD) in DSM-5 has stimulated renewed interest in understanding relationships between these behaviors and trauma-related psychopathology. This study examined the relationship between reckless and self-destructive behaviors (RSDB), intervening exposure to new adverse events, and later PTSD severity in a sample of traumaexposed veterans. At baseline, participants were assessed for RSDB (past 5 years) and current PTSD severity (N = 222). PTSD severity was then reassessed approximately 4 years later (N = 148). Overall, RSDB were reported by 74.4% of the sample, with 61.3% engaging in multiple forms of RSDB. The most commonly endorsed behaviors included alcohol/drug abuse (42.8%), driving while intoxicated (29.4%), gambling (24.7%), and aggression (23.1%). There was a positive correlation between RSDB and PTSD severity at both the baseline (r = .16, p = .031) and follow-up assessment (r = .24, p = .005). Path models indicated that exposure to new adverse events fully mediated the effect of Time 1 RSDB on PTSD symptoms at Time 2 (indirect association: β = .05, p =.046). Results suggest that RSDB are common among trauma-exposed veterans and may perpetuate PTSD symptoms by increasing exposure to new adverse events.
