This manual and workbook set focuses on anger management. The manual was designed for use by qualified substance abuse and mental health clinicians who work with substance abuse and mental health clients with concurrent anger programs. The manual describes a 12-week cognitive behavioral anger management group treatment. Each of the 12 90-minute weekly sessions is described in detail with specific instructions for group leaders, tables and figures that illustrate the key conceptual components of the treatment, and homework assignments for the group participants. The workbook enables participants to better learn, practice, and integrate the treatment strategies presented in the group sessions. The treatment model described is a combined cognitive behavioral therapy approach that employs relaxation, cognitive, and communication skills interventions. This combined approach presents the participants with options that draw on these different interventions and then encourages them to develop individualized anger control plans using as many of the techniques as possible.
