Associations between anger reductions and functional improvements among veterans in brief cognitive-behavioral conjoint therapy for PTSD.

Anger is a significant problem for military veterans with posttraumatic stress disorder (PTSD). Interventions designed to treat PTSD have been shown to decrease anger, which may be associated with improvements in psychosocial functioning. Couple-based PTSD treatments, which target both PTSD and relationship functioning, may be particularly useful for improving anger and associated psychosocial functioning. Thus, the current study sought to examine whether decreases in veterans' and partners' anger following participation in a brief couple-based treatment for PTSD (brief Cognitive Behavioral Conjoint Therapy for PTSD) is associated with improvements in psychosocial impairment and relationship satisfaction, in addition to decreases in suicidal ideation. The sample included 184 veterans and their intimate partners (92 dyads). Each partner completed measures assessing several aspects of anger (angry temperament, angry reaction, and psychological aggression). Veterans also completed measures assessing their psychosocial impairment, relationship satisfaction, and suicidality. Latent growth curve models tested whether changes in anger over the course of treatment were associated with corresponding changes in veterans' functional outcomes at the within-person and between-person levels. Findings showed that improvements in veterans' anger were associated with improvements in their psychosocial impairment and relationship satisfaction over time. Partners' psychological aggression was also associated with improvements in veterans' psychosocial impairment over time. Neither veterans' nor partners' anger was associated with veterans' suicidality. Findings add to the literature demonstrating that improvements in anger for both veterans and their partners in the context of PTSD treatment may be associated with improvements in broader psychosocial functioning for veterans.
