Translation, cross-cultural adaptation, and validation of the arabic version of the foot and ankle ability measure (FAAM-AR)

BackgroundThis study aimed to cross-cultural translate the Foot and Ankle Ability Measure to Arabic version (FAAM-AR) and to assess the psychometric properties of the FAAM-AR in a sample of Arabic-speaking participants.MethodologyThe FAAM-AR was translated according to the International Society for Quality of Life Assessment (IQOLA) guidelines. To determine construct validity, 106 participants with different foot and ankle musculoskeletal pathologies completed the FAAM-AR and SF-36. In addition, the FAAM-AR internal consistency was assessed by calculating Cronbach's alpha coefficient. Test-retest reliability was assessed using Intra-class correlation coefficient ICC_2,1.ResultsThe FAAM-AR was moderately correlated with Physical component Summary of SF-36 (ADL r = 0.67; Sport r = 0.67). Whereas, FAAM-AR showed weak correlations with Mental component Summary of SF-36 (ADL r = 0.33; Sport r = 0.19). The FAAM-AR showed excellent degree of internal consistency (ADL = 0.95; Sport = 0.92), and excellent test-retest reliability (ADL = 0.95; Sport = 0.95).ConclusionThe FAAM-AR is a valid and reliable tool for assessing ankle-foot functional status among Arabic-speaking patients with various ankle or foot musculoskeletal pathologies.
