Psychological Mindedness, Personality Structure, and Outcomes in Short-Term Group Analytic Psychotherapy.

The present study investigated the treatment effects of focused short-term group analytic psychotherapy and examined whether outcomes were predicted by the client's psychological mindedness and personality structure as measured by the Operationalized Psychodynamic Diagnosis (OPD). Treatment foci were formulated according to the OPD for 66 student counseling clients across nine groups. Two observers independently rated client psychological mindedness and personality structure. The pre-post Cohen's d effect sizes were large on the Global Severity Index (GSI) and the Inventory of Interpersonal Problems (IIP-64) and moderate on the Social Adjustment Scale Self Report, including all 66 clients starting treatment. Psychological mindedness significantly predicted two outcomes (GSI, IIP), and personality structure predicted one outcome (GSI). These measures could be helpful when selecting clients for short-term group analytic psychotherapy. We discuss study limitations and implications for future research and practice.
