Motivational Interviewing at Intake vs Intake as Usual on Client Engagement in Addiction Treatment

This K23 study is an effectiveness-implementation hybrid type I design to determine the effectiveness of Motivational Interviewing at Intake (MII), relative to intake-as-usual on client engagement and mechanisms of engagement among adults seeking outpatient addiction treatment. We also will obtain personnel feedback on the feasibility of implementing MII into standard practice by having personnel from the addiction treatment study sites complete implementation climate measures before Motivational Interviewing (MI) training and post-clinical trial, as well as an individual interview on implementation feasibility post-trial.
