Title : The effect of motivational interviewing on treatment adherence and insight levels of patients with schizophrenia: A randomized controlled study
Objective: The aim of this study is to examine the effect of motivational interviewing on treatment adherence and insight levels of patients with schizophrenia.
Method: The research was constructed in an experimental fashion as such a randomized controlled trial was utilized. Twenty of the patients comprised the intervention group while the other twenty of the patients comprised the control group. Motivational interviews were carried out on an individual basis in the form of a total of 6 interviews held once in a week with an average of 60 minutes to complete for each session. At the end of the last meeting, the intervention and control groups were post tested to solicit their motivational interviewing program reviews. After the initial posttest, the intervention and control groups underwent two more posttests on the 3rd and 6th month follow-ups.
Results: The posttests, based of Morisky Scale and carried out with the schizophrenic individuals from intervention and control groups following the last motivational interviews in three stages, showed meaningful differences. Respectively, first posttest conducted upon completion of the personal interviews yielded X2 =10.828, p=0.004, 3rd month follow-up yielded X2 =21.933, p<0.001 and 6th month follow-up yielded X2 =22.552, p<0.001.In terms of Insight Scale Total Scores, a meaningful difference was found. Respectively, first posttest conducted upon completion of the personal interviews yielded U=-2.220, p=0.026, 3rd month follow-up yielded U=-2.508, p=0.011 and 6th month follow-up yielded U=-2.953, p=0.002. The patients in the intervention group had significantly higher insight mean scores.
Conclusion: Motivational interview method plays a vital role in establishing treatment collaborations with chronic psychiatric patients, maintaining the continuity of self-care, and the acquisition of healthy lifestyle behaviors at the psychiatry clinics and the community mental health centers.
