The counseling approach to anger problems used in the training postulated that the occurrence of anger was determined by the cognitive mediational factors of expectations and appraisal. The goals of treatment were to prevent anger from occurring when it was maladaptive, to enable the person to regulate arousal and concomitant cognitions when provocation occurred, and to develop behavioral skills needed to manage provocation experiences in a problem-solving manner. Experimental participants were five juvenile probation counselors; four additional counselors served as a control group. The subjects were both males and females 27 to 38 years of age, with at least 3 years of probation counseling experience. Training was conducted in 90-minute group sessions in 7 consecutive weeks. Participants rated each session on a 5-point scale. The comparative evaluation of training effectiveness was also performed, and it involved a case history test two weeks after the training period and an unannounced intake interview test performed two months later, which assessed more enduring behavioral effects of training. The participants evaluated the training as useful and informative, demonstrated greater knowledge and more positive attitudes concerning the target problem and performed with greater proficiency than did the control counselors on an unannounced test interview 2 months after training. The consistency of the results across various dependent measures provides strong support for the hypothesized greater proficiency of the trained group of counselors. However, the effects of training on the counselors' functioning with real clients or on the target behaviors of clients themselves was not demonstrated.
