Abstract
Medication non-adherence among individuals with schizophrenia remains a persistent challenge that undermines symptom management and increases relapse and hospitalization rates. This quality improvement (QI) project aimed to evaluate the effect of Motivational Interviewing (MI) training on provider knowledge and confidence in promoting medication adherence within an outpatient mental health clinic. Guided by Lewin’s Change Theory and the Plan-Do-Study-Act (PDSA) framework, a quasi-experimental pre–post design was used. Six providers, including psychiatric nurse practitioners, therapists, a psychiatrist, and a registered nurse, participated in a structured MI training session incorporating didactic instruction and role-play exercises. Data were collected using pre- and post-intervention surveys measuring knowledge and confidence. Statistical analysis using paired-samples t-tests revealed significant improvements in both knowledge (p = .002) and confidence (p = .001) after the intervention. These findings suggest that MI training effectively enhances provider competence in addressing medication adherence and supports integration of MI into routine clinical practice. The project underscores the role of advanced practice nurses in implementing evidence-based interventions that strengthen provider–patient communication and improve adherence outcomes among patients with schizophrenia.
