Drug Compliance and Quality of Life in Individuals with Inflammatory Bowel Disease: A Descriptive and Cross-Sectional Study

Background: The incidence of inflammatory bowel diseases (IBD) is increasing. Increasing drug compliance will contribute to the improvement of patients' quality of life. Objective: This study aimed to explore any possible relationship between drug compliance and quality of life among IBD patients. Methods: Adopting a descriptive and cross-sectional research approach, this study included a sample of 251 IBD patients meeting our inclusion criteria. The research data were collected through the Participant Information Form, Harvey Bradshaw Index (HBI), Simple Clinical Colitis Activity Index (SCCAI), Morisky, Green, Levine (MGL) Adherence Scale, and Inflammatory Bowel Disease Questionnaire (IBDQ). Research data were analyzed by descriptive statistics, chi-square, Mann Whitney U, and correlation analysis. Results: Our analyses showed a weak positive but statistically significant correlation between the mean scores from the MGL Scale and IBDQ. Drug compliance was higher among patients who thought that the prescribed medication was not complicated and were aware of appropriate use of daily medication, health effects, and side effects. Patient's health-related quality of life was found to impair as the severity of disease activity increased (p
