| Popis: | The differential effectiveness of group psychotherapy was estimated in a meta-analysis of 111 experimental and quasi-experimental studies published over the past 20 years. A number of client, therapist, group, and methodological variables were examined in an attempt to determine specific as well as generic effectiveness. Three different effect sizes were computed: active versus wait list, active versus alternative treatment, and pre- to posttreatment improvement rates. The active versus wait list overall effect size (0.58) indicated that the average recipient of group treatment is better off than 72% of untreated controls. Improvement was related to group composition, setting, and diagnosis. Findings are discussed within the context of what the authors have learned about group treatment, meta-analytic studies of the extant group literature, and what remains for future research. Researchers’ understanding regarding the effectiveness of group psychotherapy has evolved over the past century. Case studies and anecdotal reports characterized the group literature in the first half of the 20th century, with the first comparative studies emerging in the 1960s (Barlow, Burlingame, & Fuhriman, 2000). Early reviews (Pattison, 1965; Rickard, 1962; Stotsky & Zolik, 1965) concluded that group therapy was a helpful adjunctive treatment, although little empirical evidence supported its use as a robust independent treatment. Reviewers in the latter part of that decade (Anderson, 1968; Mann, 1966) began to give group a heartier endorsement, describing it as capable of producing objectively measurable change in patient attitude, personality, and behavior. Throughout the 1970s, researchers repeatedly concluded that group outcomes were consistently superior to those of control groups (Bed |
