A 12-session anger control program provided relaxation training, self-cue training, assertion training, coping-strategy training and problem-solving training to adolescents with anger control problems (Feindler, Ecton, Kingsley, & Dubey, 1986). In the experimental evaluation, twenty-nine 13- to 17-year-old males were randomly assigned to either a treatment group or a control group. While in the residential program, treatment group males had significantly more appropriate, and fewer hostile, verbalizations during conflict.
