Cross-cultural adaptation, reliability, and validity of the arabic version of the foot-health status questionnaire

ObjectiveTo translate and culturally adapt the Foot Health Status Questionnaire into Arabic (Foot Health Status Questionnaire-Ar) and investigate its psychometric properties in patients with various foot conditions.DesignCross-sectional study.Setting: The study was conducted in outpatient clinics across various private and general hospitals in Saudi Arabia.ParticipantsParticipants included 135 adult patients from Saudi Arabia (83.7% females) with foot problems (mean age=38.1 years).Main measuresWe utilized the intraclass correlation coefficient and Cronbach's alpha to evaluate the test-retest reliability and internal consistency, respectively, of the Foot Health Status Questionnaire-Ar domains. To evaluate construct validity, we calculated Pearson's correlation coefficients between the Foot Health Status Questionnaire-Ar domains scores and other related constructs, including the Foot Function Index, Numeric Pain Rating Scale, and the EuroQol Health Questionnaire, five-dimension, five-level. Floor and ceiling effects were also assessed to determine the scale's ability to discriminate across the full range of scores.ResultsThe Foot Health Status Questionnaire-Ar exhibited acceptable test-retest reliability, with intraclass correlation coefficients ranging from 0.760-0.858 across four domains. Internal consistency was good, with Cronbach's α values between 0.843 and 0.912 across the domains. The construct validity was supported by significant correlations between the Foot Health Status Questionnaire-Ar domains and related constructs, including the Foot Function Index, Numeric Pain Rating Scale, and EuroQol Health Questionnaire.ConclusionFoot Health Status Questionnaire-Ar is a reliable and valid scale for evaluating foot health in Arabic-speaking populations. These results support its use in research and clinical settings for evaluating foot health.
