Anger Self-Management Training for Chronic Moderate to Severe Traumatic Brain Injury: Results of a Randomized Controlled Trial.

OBJECTIVE

To test efficacy of 8-session, 1:1 treatment, anger self-management training (ASMT), for chronic moderate to severe traumatic brain injury (TBI).

SETTING

Three US outpatient treatment facilities.

PARTICIPANTS

Ninety people with TBI and elevated self-reported anger; 76 significant others (SOs) provided collateral data.

DESIGN

Multicenter randomized controlled trial with 2:1 randomization to ASMT or structurally equivalent comparison treatment, personal readjustment and education (PRE). Primary outcome assessment 1 week posttreatment; 8-week follow-up.

PRIMARY OUTCOME

Response to treatment defined as 1 or more standard deviation change in self-reported anger.

SECONDARY OUTCOMES

SO-rated anger, emotional and behavioral status, satisfaction with life, timing of treatment response, participant and SO-rated global change, and treatment satisfaction.

MAIN MEASURES

State-Trait Anger Expression Inventory-Revised Trait Anger (TA) and Anger Expression-Out (AX-O) subscales; Brief Anger-Aggression Questionnaire (BAAQ); Likert-type ratings of treatment satisfaction, global changes in anger and well-being.

RESULTS

After treatment, ASMT response rate (68%) exceeded that of PRE (47%) on TA but not AX-O or BAAQ; this finding persisted at 8-week follow-up. No significant between-group differences in SO-reported response rates, emotional/behavioral status, or life satisfaction. ASMT participants were more satisfied with treatment and rated global change in anger as significantly better; SO ratings of global change in both anger and well-being were superior for ASMT.

CONCLUSION

ASMT was efficacious and persistent for some aspects of problematic anger. More research is needed to determine optimal dose and essential ingredients of behavioral treatment for anger after TBI.
