Systematic review of training in cognitive-behavioral therapy: Summarizing effects, costs and techniques.

Abstract

With the steadily growing importance of psychotherapeutic care, there is also an increasing need for high-quality training. We analyze the literature published between 2009 and 2022 on the effectiveness of training in cognitive behavioral therapy. The review addresses current gaps in the literature by focusing on the description of specific training components and their associated costs, as well as examining therapist-level predictors of training effectiveness. Our findings confirm the effect of additional supervision on both therapist competence and patient outcomes. Instructor-led training and self-guided web-based training seem to moderately increase competence, especially when targeting specific and highly structured treatments or skills. The level of prior training and experience of a therapist appears to predict the strength of training-related gains in competence. Few studies analyzed the differential effect of certain elements of training (e.g., the amount of active learning strategies) and training costs were generally not reported. Future studies should replicate or expand the existing evidence on active ingredients and therapist-level predictors of training effectiveness. Costs should be systematically reported to enhance the comparability of different training strategies.
