This expanded edition of this successful Therapist Guide provides an evidence-based treatment protocol for all types of substance use disorders. Designed to be used with the accompanying Workbook, this guide provides clinicians with valuable strategies for working with clients with substance use disorders. The treatment outlined focuses on specific issues involved in both stopping substance abuse and changing behaviours or lifestyle aspects that contribute to continued substance abuse. In addition to addressing professional approaches/attitudes toward the substance abusing client, assessment, psychosocial and pharmacotherapeutic treatment, and self-help programs, this expanded edition also includes a new chapter on the management of a co-occurring psychiatric disorder.
