Foot pain has a significantly detrimental effect on mobility, function and health status. Researchers have developed a number of measurement tools to assess foot health and its impact on the quality of life. This study was conducted to translate the original English Manchester Foot Pain and Disability Index (MFPDI) into Persian and to examine the psychometric properties of the Persian version.
A total of 206 patients with a range of foot disorders filled out the Persian version of the MFPDI and the Short-Form 36 Health Survey (SF-36). The Persian version of the MFPDI was re-completed by the participants at an interval of five to seven days. The analyses performed included internal consistency, test-retest reliability, construct validity, and floor and ceiling effect analysis.
The Persian MFPDI had a good internal consistency (Cronbach's α≥0.70) and test-retest reliability (ICC=0.84). The construct validity of the Persian MFPDI was demonstrated to be acceptable as a result of its significantly strong negative correlations with the SF-36.
The results of this study showed that the Persian version of the MFPDI is a valid and reliable measure to assess foot-related disability.
足部疼痛对活动能力、功能和健康状况有显著的不利影响。研究人员已经开发了许多测量工具来评估足部健康及其对生活质量的影响。本研究旨在将原始英文的曼彻斯特足部疼痛和残疾指数（MFPDI）翻译成波斯语，并检验波斯语版本的心理测量学特性。
共有 206 名患有各种足部疾病的患者填写了波斯语版的 MFPDI 和简明 36 健康调查（SF-36）。参与者在 5 到 7 天的时间间隔内重新填写了波斯语版的 MFPDI。进行的分析包括内部一致性、测试-重测信度、结构有效性以及地板和天花板效应分析。
波斯语版的 MFPDI 具有良好的内部一致性（Cronbach's α≥0.70）和测试-重测信度（ICC=0.84）。波斯语版 MFPDI 的结构有效性可接受，因为它与 SF-36 呈显著的负相关。
本研究结果表明，波斯语版的 MFPDI 是一种有效且可靠的评估足部相关残疾的测量工具。
