Translation, cross-cultural adaptation, and validation of the Arabic version of the Foot and Ankle Ability Measure (FAAM-AR)

Umar Alabasi
Purpose:

The purpose of this study was to translate and cross-culturally validate the FAAM into Arabic language, as well as assessing its psychometric properties including acceptability, reliability, and 

validity


Methods:

FAAM was translated According to the forward/backward strategy. 106 participants were enrolled, they filled out both FAAM-AR ADL and FAAM-AR Sport subscales, in addition to the SF-36 questionnaire. Cronbach alpha was conducted for assessing FAAM-AR’s internal structure. Using of the intra-class correlation coefficient ICC2,1 to assess the tests-retest reliability. Standard error of measurement SEM was calculated to obtained the minimal detectable change MDC. Spearman’s correlation coefficient was used to assess the correlation between FAAM-AR and SF- 36 components for evaluating FAAM-AR validity.

Results:

Our study found that FAAM-AR has a strong reliability and validity evidence, verified by a strong degree of internal consistency in the Cronbach’s alpha assessment (ADL=0.95; Sport=0.92), and excellent test re-test reliability in the ICC2,1 assessment (ADL=0.95; Sport=0.95), with a reasonable amount of measurement error (ADL±4.27; SPORT±5.57) and minimal detectable change (ADL±11.82; SPORT±15.43). Furthermore, FAAM-AR was moderately correlated with the Physical Component Summary of SF-36 (ADL r=0.67; SPORT r=0.67). Whereas, FAAM-AR showed a weak correlation with the Mental component Summary of SF- 36 (ADL r=0.33; SPORT r=0.19).

Conclusion(s):

This study provides a strong evidence for FAAM-AR reliability and validity for assessing ankle-foot complex functional status, among patients with ankle or foot disorders.

Implications:

Using FAAM-AR in clinical daily practice for clinicians in Arabic speaking communities, as well as using FAAM-AR as an outcome measure in research that aims to study the functional status of the ankle-foot complex would help significantly in restoring functional ability.
