Components of an MST program include: (1) a site assessment to identify organizational and community conditions conducive to developing a sustainable MST program; (2) 5-day orientation training for clinicians and supervisors; (3) quarterly booster sessions; (4) on-site weekly clinical supervision of the MST team by a doctoral-level or advanced master’s level professional; and (5) ongoing telephone consultation from an MST consultant for the team and supervisor. The document focuses on telephone consultation by an MST expert, because this function is designed to support ongoing therapist and supervisory fidelity to the MST treatment model. The manual describes the expertise of MST consultants, consultation as a teaching process, consultation skills that facilitate learning, the structure and process of weekly telephone consultation, and strategies to facilitate supervisor implementation of MST supervision practices.
