Abstract
Background and Objective: This study aimed to evaluate the reliability and validity of the Persian version of the osteoarthritis short health literacy questionnaire (OSHL) for musculoskeletal patients (LiMP) among individuals with osteoarthritis in Iran.
Material and Methods: A cross-sectional validation study was conducted with 420 patients aged 45–75 years, recruited from the rheumatology clinic of Shahid Beheshti Hospital in Hamadan. The LiMP questionnaire underwent a rigorous translation and back-translation process. Psychometric evaluation included assessments of face validity (qualitative interviews and item impact scores), content validity (expert panel review, Content Validity Ratio [CVR], and Content Validity Index [CVI]), and construct validity (exploratory and confirmatory factor analyses). Reliability was examined using Cronbach’s alpha for internal consistency and the intraclass correlation coefficient (ICC) for test-retest stability.
Results: The Persian LiMP demonstrated strong face and content validity, with all items achieving impact scores above 1.5, a CVR of 0.86, and a CVI of 0.95. Exploratory factor analysis identified a three-factor structure: Musculoskeletal Conditions, F2: Musculoskeletal Diagnosis and treatment, and F3:Anatomy and terminology; accounting for 71.07% of the variance, confirmed by confirmatory factor analysis with good model fit indices (e.g., the Comparative Fit Index = 0.962, the root mean square error of approximation = 0.083). All subscales showed high internal consistency (Cronbach’s alpha > 0.70) and satisfactory test-retest reliability (mean the Intraclass correlation coefficient = 0.789). Convergent and discriminant validity were generally supported.
Conclusions: The Persian version of the LiMP for musculoskeletal patients is a reliable and valid instrument for assessing health literacy in this population. Its use can facilitate targeted interventions and improve patient outcomes.
