Abstract
Context: Hyperuricemia and gout has been found to be associated with reduced health-related quality of life (HRQoL); however, there is no available Bengali questionnaire assessing the same. Aims: We aimed to develop the Bengali version of a questionnaire and examine its cross-cultural adaptability considering linguistic equivalence. Settings and Design: A multicentric, mixed methods, cross-sectional study was conducted through consecutive sampling at the outpatients of three homeopathic hospitals in West Bengal. Subjects and Methods: The Bengali version of the questionnaire was produced by standardized forward–backward translations. Psychometric analysis was run to examine its factor structure, validity, and reliability. Statistical Analysis Used: Reliability was examined using internal consistency (n = 210). Construct validity was examined by exploratory factor analysis (n = 105) using principal component analysis (PCA; varimax rotation). Subsequently, confirmatory factor analysis (CFA; n = 105) was performed to verify the model fit. Results: The internal consistency (Cronbach's α =0.880; 95% confidence interval 0.855–0.902), test–retest reliability and concurrent validity of the questionnaire– all were within acceptable limits. The (Kaiser–Meyer–Olkin = 0.832) and Bartlett's test of sphericity (Chi-square: 1644.344 at df = 210, P
