ABSTRACT
We longitudinally investigated coping among male military veterans (n = 98) with posttraumatic stress disorder (PTSD) symptomatology and a co-occurring substance use disorder (SUD) who participated in a randomized controlled trial of seeking safety (SS). Participants were randomized to SS or intensive treatment-as-usual (TAU) for SUD. Coping (active, avoidant, emotional discharge), and PTSD and SUD symptomatology were measured prior to and at the end of treatment, and at 6- and 12-month follow-ups. Among the total sample, we found that: (a) avoidant and emotional discharge, but not active, coping tended to be positively associated with PTSD and SUD symptomatology at baseline; (b) active coping increased and avoidant and emotional discharge coping decreased during the 12-month time-period; and (c) avoidant and emotional discharge, but not active, coping longitudinally covaried with PTSD and SUD symptomatology. Results suggest the utility of targeting maladaptive coping in treatments for individuals with co-occurring PTSD and SUD.

Though there has been a recent surge of interest in the relations between facets of mindfulness and Posttraumatic Stress Disorder (PTSD), there has been a dearth of empirical studies investigating the impact of changes in facets of mindfulness on PTSD treatment outcomes. The present study tested the prospective associations between pre- to post-treatment changes in facets of mindfulness and PTSD and depression severity at treatment discharge, among 48 military Veterans in residential PTSD treatment adhering to a cognitive-behavioral framework. Together, changes in facets of mindfulness significantly explained post-treatment PTSD and depression severity (19-24% of variance). Changes in acting with awareness explained unique variance in post-treatment PTSD severity and changes in nonjudgmental acceptance explained unique variance in post-treatment depression severity. These results remained significant after adjusting for shared variance with length of treatment stay.
