Background And Aims:
Osteoarthritis (OA) is a degenerative joint disease characterized. The Mini-Osteoarthritis Knee and Hip Quality of Life (Mini-OAKHQoL) scale is used to evaluate the impact of knee/hip osteoarthritis (KOA/HOA) on patients' quality of life (QoL). This study aims to ascertain the consistency and accuracy of the Mini-OAKHQoL Syrian Arabic version.
Method:
This cross-sectional study translated the original version of the Mini-OAKHQoL into Syrian Arabic using a standard method for language adjustment. The patients completed the Syrian Arabic version and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Short Form-36 (SF-36) scales. The psychometric properties of the Syrian Arabic Mini-OAKHQoL were evaluated using Cronbach's α for internal consistency, intraclass correlation coefficient (ICC) for test-retest reliability, and Spearman's correlation coefficient for convergent validity. Statistical significance was set at p < 0.05.
Results:
This study included 87 persons with KOA/HOA. The Mini-OAKHQoL demonstrated satisfactory face and content validity. The intraclass correlation coefficient, confidence intervals (ICC = 0.844, 95% CI: 0.76-0.90). for the overall score with a cut-off > 0.5. The Cronbach's α for the categories was satisfactory internal consistency (α > 0.7). Regarding the assessment of convergent validity, physical activities, mental health, pain, and independent items of the Mini-OAKHQoL Arabic version demonstrated moderate to high correlations with the WOMAC and SF-36.
Conclusion:
The Mini-OAKHQoL is a well-validated and reliable scale for evaluating QoL in patients with KOA/HOA, demonstrating strong utility in both clinical practice and research settings among Arabic-speaking populations.
