Objectives: A national survey finds that 62% of social work programs do not require didactic and clinical supervision in any empirically supported psychotherapy (EST). The authors report the results of analysis of national survey data using two alternative classifications of EST to determine if the results are because of the definition of EST used in the national survey. Method: Psychotherapies in the national survey are classified by three definitions of EST. Data are weighted to provide estimates generalizable to the population of social work programs. Results: The classification of EST does not have a major impact on the findings of the national survey. The national survey definition produce estimates of training in any EST in social work that fall between the two alternate definitions. Conclusions: Regardless of which definition is used, the data clearly show that the majority of social work programs offer little training in EST. (Contains 3 tables.)
