Motivational Interviewing Effect on Medication Adherence and Other Outcomes in People with Schizophrenia (PwS): A Review

Adherence will have an impact on therapy because schizophrenia is a chronic mental disorder that requires long-term treatment. One strategy to improve adherence to medications is motivational interviewing (MI), although more study is needed to see how well it works and whether it has any other effects on schizophrenia. The study aimed to assess the effectiveness of motivational interviews in improving adherence to medications and other positive impacts on PwS. A literature review using PubMed, Science Direct, Springerlink, and google scholar databases from 2010-2023 focused on keywords adherence, schizophrenia, and motivational interviewing. The results showed that MI has inconsistencies in their effect on improving medication adherence in PwS, but some studies found evidence of an association between MI and other outcomes, such as improvement in psychotic symptoms and decreased hospitalisation rates. Differences in patient characteristics and MI interventions in each study, the to perform MI techniques, and the trusting relationship built by the counsellor with the patient will affect the impact of MI on adherence. MI showed inconsistencies in improving medication adherence in people with schizophrenia. Several factors will affect the effectiveness of MI. However, MI also has the potential to improve psychosis symptoms and reduce hospitalisation rates, although more research is needed. © 2023 The Authors, published by EDP Sciences.
