With the recognition that addiction, in its many forms, permeates most forms of clinical practice irrespective of treatment setting as well as most major medical problems, the demand for concise evaluation and treatment for substance use has increased. Social group work and addiction treatment are natural allies. This is partly because individuals who abuse substances are more often willing to stay sober and committed to treatment when it is provided in social groups, apparently because of the rewarding and therapeutic benefits such as affiliation, confrontation, support, gratification, and identification. The overall capacity of social group work to bond individuals having a substance use disorder to treatment is an important asset because greater the amount, quality, and duration of treatment, the better the patient’s prognosis.
