A Randomized Controlled Trial of Two Methods to Improve Motivational Interviewing Training

Purpose: This randomized controlled study examines the efficacy of two innovative methods to teach beginning motivational interviewing (MI) skills: live supervision (LS), a small group experiential learning interaction with standardized client actors and in-the-moment guidance from a supervisor, and a coding learning (CL) method, where students in a classroom setting are introduced to MI skill development via learning to code MI practice behaviors. Methods: Seventeen social work students in a child welfare training program were randomized to receive either LS or CL training method. Changes in MI knowledge, attitudes, and MI skill were assessed through self-report and observational measures pretraining, posttraining, and at 5 months follow-up, after a semester of learning-as-usual. Results: Both training groups demonstrated an improvement in MI knowledge and attitudes from pretest to follow-up. MI skill gain within groups varied for specific MI skills. Discussion: Implications for maximally efficient MI training are advanced.
