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

Abstract

Objective

To 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.

Design

Cross-sectional study.

Setting: The study was conducted in outpatient clinics across various private and general hospitals in Saudi Arabia.

Participants

Participants included 135 adult patients from Saudi Arabia (83.7% females) with foot problems (mean age=38.1 years).

Main measures

We 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.

Results

The 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.

Conclusion

Foot 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.
