Question In people with anger problems, does cognitive behavioural therapy (CBT) reduce anger?
Studies were identified using PsycINFO and Dissertation Abstracts (197095) with the terms anger control, anger treatment, and anger management.
Studies were selected if they included
4 patients, involved CBT for anger, and reported
1 anger related dependent variable. Studies that used cognitive or behavioural interventions alone or that aimed only to promote relaxation were excluded.
Data were extracted on patient characteristics and numbers, study design, and dependent variables.
50 studies (1640 patients) were included. Patient groups studied included abusive parents and abusive spouses, schoolchildren, clinical adolescents, juvenile delinquents, inmates, and college students. Effect sizes were calculated from self reports of anger, dependent measures of anger and aggression, and behavioural ratings of aggression, and averaged across variables to produce 1 effect size per study. The effect sizes for the 50 studies ranged from -0.32 to 1.57 (SD 0.43) with all effect sizes but one positive in value. The grand mean weighted
