The Satisfaction With Therapy and Therapist Scale--Revised (STTS-R) for group psychotherapy: Psychometric properties and confirmatory factor analysis.

Abstract

Patients' level of satisfaction with their therapeutic experience is a concept that is important for understanding treatment efficacy; however, patient satisfaction has received little empirical attention. The Satisfaction With Therapy and Therapist Scale (STTS) developed for group psychotherapy by T. P. S. Oei and G. J. Shuttlewood (1999) was designed to assess patients' level of satisfaction with their therapeutic endeavor. This article aims to strengthen the STTS's psychometric properties by using confirmatory factor analysis (CFA) with a large sample of patients with mood and anxiety disorders. Outpatients (N = 344) took part in the study. Exploratory factor analysis indicated 2 conceptually coherent factors that accounted for 66.9% of the variance. The 2 factors, which were similar to those found in Oei and Shuttlewood (1999), namely, Satisfaction With Therapy and Satisfaction With Therapist, were replicated. CFA revealed a 2-factor solution to be the best-fitting model. Overall, this article demonstrated that the STTS-R has sound psychometric properties and would serve as a useful instrument in assessing a patient's level of satisfaction with both group therapy and therapist in research as well as in clinical settings.
