Abstract

Introduction: Decision-support intervention has tools called decision-aids which are designed to facilitate shared decision making (between doctor-patient-family). Decision-aids come in a variety of formats (e.g., booklets, websites, videos). “Making Treatment Decisions That are Right for You” is a booklet which can help patients with bipolar II make evidence-based, medical and psychological choices that are consistent with their values and preferences. This research was conducted with the aim of determining the effectiveness of aforementioned booklet on treatment adherence of patients with bipolar II.

Methods: This study was conducted with a quantitative approach and a semi-experimental method using a pre-test-post-test design with a control group. Statistical population of this study consisted of men and women with bipolar II disorder living in Isfahan who referred to Masir Roshd Psychological Clinic or Shahid Modares Psychiatric Hospital on an outpatient basis in 2023. 30 people with bipolar disorder type II were selected and randomly divided into experimental and control groups (n=15 each). Convenience sampling was chosen for this research. Both experimental and control groups answered the Treatment Adherence Questionnaire as pretest. The experimental group underwent decision-support intervention based on the booklet called “Making Treatment Decisions That Are Right for You” and the concept of the booklet was explained to patients in four 45-minute sessions so that they could make their treatment decisions in consultation with their doctor, psychologist and family; while the members of control group started and continued the treatment process with treatment decisions made by their doctor/psychologist (paternalistic models of treatment decision-making). After 2 months, post-test was given to the experimental and control groups. Finally, data were interpreted through multivariate covariance analysis.

Result: Findings showed that decision-support intervention was effective on improving components of treatment adherence, including " diligence in treatment, participation, adherence and commitment in treatment" with squared values of 0.35, 0.24, 0.30 and 0.64, respectively.

Discussion and conclusion: It can be concluded that decision-support intervention based on the booklet called “Making Treatment Decisions That are Right for You” is a suitable option for improving and increasing treatment adherence in bipolar II patients.
