Objectives: To investigate the efficacy of a brief, manual-based group ther
apy for adolescents with poor anger control. A previously developed anger m
anagement treatment package of 10 to 12 sessions was condensed to a 4-sessi
on package to be given within 2 weeks. Immediate effectiveness and the tran
sfer of skills were investigated; anger management skills not only had to b
e acquired, they also had to be used in the adolescents' natural social int
eractions. Method: Fifty adolescent psychiatric inpatients were selected fo
r high levels of anger and randomly assigned to treatment or control condit
ions. Pre- and posttreatment measures were administered to subjects and adu
lts who rated the subjects' behaviors. Results: Pre/post self-report measur
es, as well as behavior ratings by adults, indicated that the patients who
went through the anger management series exhibited significantly improved s
kills. Conclusions: These results suggested that the intervention for adole
scents was effective even though it was condensed, but it should not be fur
ther abbreviated.
