We present a model of training in evidence-based psychosocial treatments (EBTs). The ACCESS (assess and adapt, convey basics, consult, evaluate, study outcomes, sustain) model integrates principles and findings from adult education and training literatures, research, and practical suggestions based on a community-based clinician training program. Descriptions of the steps are provided as a means of guiding implementation efforts and facilitating training partnerships between public mental health agencies and practitioners of EBTs.
