The Functional index of hand osteoarthritis (FIHOA) is a commonly used patient-reported outcome questionnaire designed to measure function in patients with hand osteoarthritis. The objective of this study was to evaluate the validity and reliability of the Persian version of the FIHOA. The Persian-translated version of FIHOA was administered to 72 native Persian-speaking patients in Iran with hand osteoarthritis. Thirty-six of the patients completed the questionnaire on two occasions 1 week apart. The physical component of the SF-36 and a numerical rating scale were used to evaluate the construct validity of the Persian version of FIHOA. Internal consistency was high (Cronbach's alpha = 0.89). Test-retest reliability for the total score was excellent (weighted kappa = 0.89, 95% CI 0.79-0.94). A significant positive correlation between total FIHOA score and numerical rating scale (r = 0.70) and a significant negative correlation between total FIHOA score and the physical component scale of the SF-36 (r = -0.76) were observed. The Persian version of the FIHOA showed adequate validity and reliability to evaluate functional disability in Persian-speaking patients with hand osteoarthritis.
手部骨关节炎功能指数（FIHOA）是一种常用的患者报告结局问卷，旨在测量手部骨关节炎患者的功能。本研究的目的是评估FIHOA波斯语版本的有效性和可靠性。将FIHOA的波斯语翻译版本应用于伊朗72名以波斯语为母语的手部骨关节炎患者。其中36名患者在相隔1周的两个时间点完成了问卷。使用SF-36的身体成分和数字评分量表来评估FIHOA波斯语版本的结构效度。内部一致性较高（Cronbach's α = 0.89）。总分的重测信度极佳（加权kappa = 0.89，95%CI 0.79 - 0.94）。观察到FIHOA总分与数字评分量表之间存在显著正相关（r = 0.70），FIHOA总分与SF-36的身体成分量表之间存在显著负相关（r = -0.76）。FIHOA波斯语版本在评估波斯语手部骨关节炎患者的功能残疾方面显示出足够的有效性和可靠性。
