The success of IM for addiction depends on therapist facilitation and quality of subject's daily practice (home-work). The description of each facilitation meeting and assigned homework are listed in the therapist manual available upon request. In general, each session the therapist will 1) get feedback from prior session and daily IM practice; 2) teach new components of IM step by step; 3) link IM technique to the addiction problem and prevention of relapse.
