How does an individual practitioner, agency, or treatment system get from making a decision or being mandated to adopt an evidence-based practice (EBP) to successfully implementing and using the EBP? Research and theory on factors that help or hinder putting new treatments into practice focus on individual, organizational, and external levels. Although several factors have been identified that affect implementation, the level and specificity of evidence do not warrant the term evidence-based implementation strategies. Yet steps must be taken now to start using EBPs. This article includes a review of research and theory on implementation, a case example of statewide implementation, and recommendations for psychologists across multiple roles to assist in advancing the implementation of EBPs into clinical practice.
