AB0658 Cross-Cultural Adaptation, Reliability, and Validity of the Turkish Version of the Compliance Questionnaire on Rheumatology (CQR-T) in Patients with Behçet's Disease

BackgroundCompliance to treatment can be defined as the degree to which patient behavior is consistent with the recommendations made by healthcare providers. Determining the level of the patient's compliance will improve the management of a certain disease. Currently, the only self-reported questionnaire for assessing the compliance of patients with rheumatic disease is the 19-item Compliance Questionnaire on Rheumatology (CQR).ObjectivesThe aim of this study was to examine the psychometric properties of the Turkish version of the Compliance Questionnaire on Rheumatology (CQR-T) for patients with Behçet's disease (BD)MethodsA sample of 105 Turkish patients with BD participated in this study. The scale was cross-culturally adapted through a process including translation, comparison with versions in other languages, back translation, and pretesting. Construct validity was evaluated by factor analysis, and criterion validity was evaluated using the Morisky Medication Adherence Scale (MMAS).ResultsThe mean age of the study group was 30.87±8.06 years. The majority of the participants was male (89.5%). Mean disease duration was 5.67±4.68 years.Among the current medical treatment agents, colchicine and azathioprine were the most commonly used (79 and 50 patients, respectively). The CQR-T demonstrated acceptable internal consistency (Cronbach's alpha coefficient = 0.832), adequate test–retest reliability (intraclass correlation coefficient = 0.630), and correlations with MMAS scores (r=−0.389; p
