title: Within-Provider Variability in Motivational Interviewing Integrity for Three Years after MI Training: Does Time Heal?
abstract: This study examined variability in Motivational Interviewing (MI) integrity among 15 providers for three years following training. Data come from an effectiveness trial in which providers were trained to deliver brief single-session MI interventions. Each session was audio-recorded and coded for MI integrity using the Motivational Interviewing Treatment Integrity (MITI) 3.1.1 rating system. Within-provider variation in MI integrity was large, especially for behavior count scores (e.g., open questions, complex reflections) and only slightly smaller for global session scores of MI Spirit and Empathy. Within-provider variability was in most cases larger than between-provider variability and there was no evidence that providers improved appreciably over time. These findings raise concerns about the quality of MI being delivered in large-scale implementation efforts and have implications for the monitoring and training of higher quality MI.
