This volume analyzes selected state-of-the-art addiction research presently being conducted by leaders in the field. It critically evaluates the assessment and treatment strategies that are used in addiction research. The contributors to Part I address the assessment of addictive disorders, covering issues such as self-monitoring; social/family interaction patterns, self-efficacy and relapse determinants, and drinking patterns over time. In Part II, the treatment section, they examine aversion therapy for both cigarette smokers and alcoholics, coping-response counseling, the effectiveness of relapse prevention, and a job-training program for heroin addicts.
