While behavior change counseling (BCC) targeting health risk behaviors has shown efficacy for improving patient health outcomes, barriers to knowledge translation have resulted in poor uptake among health care providers (HCPs). This article outlines the development of a new BCC training framework for HCPs, from inception to readiness for efficacy testing. It provides an example of integrated knowledge translation (iKT) used in alignment with the obesity-related behavioral intervention trials model. (a) A modified Delphi process identified essential BCC skills for HCPs; (b) a survey assessed HCP attitudes and training needs; (c) an online competency assessment tool was developed using iKT mixed methods; (d) a training program was developed and refined using a logic model; and (e) the program was optimized using iterative rounds of participant feedback. A future proof-of-concept trial (f) will determine the program's readiness for full efficacy testing. A Delphi panel (n = 46) identified 11 core BCC competencies for HCPs, defining "motivational communication." The HCP survey (n = 80) showed willingness to devote 4 hr to introductory training in BCC. The Motivational Communication Competency Assessment Test (MC-CAT: an online, interactive evaluation tool) and a motivational communication training program (MOTIVATOR: accredited for continuing education by the Royal College of Physicians and Surgeons of Canada) were collaboratively developed with knowledge users. The optimization process (n = 11) provided key feedback, with minor changes being made to the program. In developing a new BCC framework, obstacles to BCC implementation were addressed through an iterative iKT process. This should improve eventual intervention uptake.
