Abstract

Providing clinicians with a clearer understanding of how clients' recover over the entire course of therapy has important implications for referral and treatment strategies. The present study compares rates of change in 160 clients in group therapy with 6632 clients in individual therapy and 864 clients receiving both individual therapy and group therapy. Therapeutic outcomes were measured using the Outcome Questionnaire-45. Data was analyzed using Hierarchical Linear Modeling (HLM), also called Multi-Level Modeling (MLM), to produce recovery curves for clients in each group. Recovery curves showed that most change occurred in the early part of group therapy and slowed near the end. Rates of change for clients in group, individual and conjoint therapy formats were also compared. This study reports that no significant differences in rates of recovery were found between group and individual or group and conjoint treatment formats. However, a significant difference was detected when individual and conjoint treatments were compared, with the individual sample improving at a faster rate.
