In an effort to maximize both the quality and cost-effectiveness of psychodynamic therapies, psychodynamic therapists have recently been called to scientifically demonstrate their claims of treatment efficacy (Gabbard, Gunderson, & Fonagy, 2002). This pilot study was completed in response to the need for data on long term effects of psychodynamic psychotherapy and information on the degree to which gains made in therapy are maintained following treatment. This study used a single-group, within-subjects, longitudinal design. The Outcome Questionnaire-45.2 was utilized as a measure of change over time, with measurements taken at intake, every 3 months throughout the course of dynamic psychotherapy, at termination, and at 12 to 18 months post-termination. Results of mixed effect analyses of variance indicated statistically significant change occurring between intake and 12 to 18 months post-termination of treatment, with a large effect size (d = 1.11). Comparisons between termination and 12 to 18 months post-termination of treatment were indicative of a large, positive, and significant relationship. Overall, psychodynamic psychotherapy appeared to be an effective treatment for a range of presenting problems, and the gains made during a course of treatment were generally sustained across a timeframe of over one year. Clinical and research implications of the results are provided, as well as recommendations for practicing clinicians and future research efforts in this area.
