Abstract

Introduction: Decision-support interventions include tools known as decision aids, which are designed to facilitate shared decision-making among doctors, patients, and their families. Decision aids come in various formats, such as booklets, websites, and videos. Treatment Decisions That Are Right for You is a booklet that can assist patients with bipolar II in making evidence-based medical and psychological choices that align with their values and preferences. This research aimed to assess the effectiveness of the aforementioned booklet on the treatment adherence of patients with bipolar II.
Method: This study was conducted using a quantitative approach and a semi-experimental method employing a pre-test-post-test design with a control group. The statistical population of this study comprised men and women with bipolar II disorder residing in Isfahan who sought treatment at Masir Roshd Psychological Clinic or Shahid Modares Psychiatric Hospital on an outpatient basis in 2023. Thirty individuals with bipolar disorder type II were randomly selected and divided into experimental and control groups (n=15 each). Convenience sampling was utilized for this research. Both the experimental and control groups completed the Treatment Adherence Questionnaire as a pretest. The experimental group received decision-support intervention based on the booklet titled “Making Treatment Decisions That Are Right for You.” The content of the booklet was explained to patients in four 45-minute sessions, enabling them to make treatment decisions in collaboration with their doctor, psychologist, and family. In contrast, the control group members initiated and continued the treatment process based on decisions made by their doctor/psychologist (paternalistic models of treatment decision-making). After 2 months, a post-test was administered to both the experimental and control groups. Subsequently, the data were analyzed using multivariate covariance analysis.
Results: Findings showed that the decision-support intervention was effective in improving components of treatment adherence, such as 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 a decision-support intervention based on the booklet titled “Making Treatment Decisions That are Right for You” is a suitable option for improving and increasing treatment adherence in patients with bipolar II disorder.
