Peeking into the black box: mechanisms of action for anger management treatment.

We investigated potential mechanisms of action for anger symptom reductions, specifically, the roles of anger regulation skills and therapeutic alliance on changes in anger symptoms, following group anger management treatment (AMT) among combat veterans with posttraumatic stress disorder (PTSD). Data were drawn from a published randomized controlled trial of AMT conducted with a racially diverse group of 109 veterans with PTSD and anger symptoms residing in Hawaii. Results of latent growth curve models indicated that gains in calming skills predicted significantly larger reductions in anger symptoms at post-treatment, while the development of cognitive coping and behavioral control skills did not predict greater symptom reductions. Therapeutic alliance had indirect effects on all outcomes mostly via arousal calming skills. Results suggest that generalized symptom reduction may be mediated by development of skills in calming physiological arousal. In addition, arousal reduction skills appeared to enhance one's ability to employ other anger regulation skills. Published by Elsevier Ltd.
