A lack of effective therapist training is a major barrier to evidence-based intervention (EBI) delivery in the community. Systematic reviews published nearly a decade ago suggested that traditional EBI training leads to higher knowledge but not more EBI use, indicating that more work is needed to optimize EBI training and implementation. This systematic review synthesizes the training literature published since 2010 to evaluate how different training models (workshop, workshop with consultation, online training, train-the-trainer, and intensive training) affect therapists' knowledge, beliefs, and behaviors. Results and limitations for each approach are discussed. Findings show that training has advanced beyond provision of manuals and brief workshops; more intensive training models show promise for changing therapist behavior. However, methodological issues persist, limiting conclusions and pointing to important areas for future research.
