Recognizing an urgent need for increased access to evidenced-based psychological treatments, public health authorities have recently allocated over $2 billion to better disseminate these interventions. In response, implementation of these programs has begun, some of it on a very large scale, with substantial implications for the science and profession of psychology. But methods to transport treatments to service delivery settings have developed independently without strong evidence for, or even a consensus on, best practices for accomplishing this task or for measuring successful outcomes of training. This article reviews current leading efforts at the national, state, and individual treatment developer levels to integrate evidence-based interventions into service delivery settings. Programs are reviewed in the context of the accumulated wisdom of dissemination and implementation science and of methods for assessment of outcomes for training efforts. Recommendations for future implementation strategies will derive from evaluating outcomes of training procedures and developing a consensus on necessary training elements to be used in these efforts.
