Abstract
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.
