The natural propensity of human beings to congregate makes group therapy a powerful therapeutic tool for treating substance abuse, one that is as helpful as individual therapy, and sometimes more successful. One reason for this efficacy is that groups intrinsically have many rewarding benefits—such as reducing isolation and enabling members to witness the recovery of others—and these qualities draw clients into a culture of recovery. Another reason groups work so well is that they are suitable especially for treating problems that commonly accompany substance abuse, such as depression, isolation, and shame.
The lives of individuals are shaped, for better or worse, by their experiences in groups. People are born into groups. Throughout life, they join groups. They will influence and be influenced by family, religious, social, and cultural groups that constantly shape behavior, self‐image, and both physical and mental health.
Groups can support individual members in times of pain and trouble, and they can help people grow in ways that are healthy and creative. However, groups also can support deviant behavior or influence an individual to act in ways that are unhealthy or destructive.
Because our need for human contact is biologically determined, we are, from the start, social creatures. This propensity to congregate is a powerful therapeutic tool. Formal therapy groups can be a compelling source of persuasion, stabilization, and support. Groups organized around therapeutic goals can enrich members with insight and guidance; and during times of crisis, groups can comfort and guide people who otherwise might be unhappy or lost. In the hands of a skilled, well‐trained group leader, the potential curative forces inherent in a group can be harnessed and directed to foster healthy attachments, provide positive peer reinforcement, act as a forum for self‐expression, and teach new social skills. In short, group therapy can provide a wide range of therapeutic services, comparable in efficacy to those delivered in individual therapy. In some cases, group therapy can be more beneficial than individual therapy (Scheidlinger 2000; Toseland and Siporin 1986).
