Effect of Motivational Interviewing on Medication Adherence in Patients with Bipolar Disorder: Systematic Review

This systematic review was conducted to examine the effect of motivational interviewing method on compliance with medication treatment in individuals diagnosed with bipolar disorder. In this systematic review, the literature was searched in the databases of ''Cochrane, SpringerLink, Ovid, Science Direct, PubMed, ProQuest, Networked Digital Library of Theses and Dissertations (NDLTD), ULAKBIM, YÖKTEZ'', published in the last 5 years, in English language, using the keywords and combinations of ''motivational interviewing'', ''bipolar disorder'', ''adherence''. The titles and abstracts of the studies were reviewed and 6 studies, including 4 randomized controlled trials and 2 nonrandomized studies, that met the inclusion criteria were included in the systematic review. As a result of this systematic review, it was determined that the motivational interviewing method was effective in increasing medication compliance in patients diagnosed with bipolar disorder. In the studies, it was determined that motivational interviewing was applied alone, with medication reminder system or with an educational program. It was determined that motivational interviewing was applied twice a week or twice a month, between 20-60 minutes and between 3-6 sessions. Subjective and objective measurement tools assessing medication adherence and symptoms were used to evaluate the effect of motivational interviewing. It is recommended to increase randomized controlled experimental research examining the effect of motivational interviewing method on medication adherence in patients diagnosed with bipolar disorder and to use motivational interviewing techniques and skills by mental health professionals to increase patients' medication adherence.
