Can we differentiate between psychoanalytic and psychodynamic psychotherapy? - An empirical investigation of therapists' self-reports.

Abstract

Therapy differentiation is a crucial component of psychotherapy research. It refers to whether inspected treatments differ from one another. In the history of psychoanalysis, the differentiation between psychodynamic and analytic psychotherapy was often discussed but seldom inspected empirically. In this study, we propose a set of items which should in theory offer the possibility to differentiate between psychodynamic and analytic psychotherapy on session level. We inspect these items using therapists' self-reports concerning N = 295 cases of different psychodynamic and analytic therapies. Results of an exploratory factor analysis and subsequent inspections of the psychodynamic and analytic items in different forms of therapies strengthen the usability of these items for differentiating between psychodynamic and analytic therapy. However, further studies using different perspectives (e. g., observer ratings) are essential. The presented items are a promising step towards the development of an instrument for treatment differentiation which could later be used in treatment comparison studies.
