Translation, cross-cultural adaptation, and measurement properties of the Arabic version of the fear avoidance components scale.

This study aimed to translate, validate, and cross-culturally adapt the original FACS into the Arabic language. The English version of the FACS was translated and culturally adapted into Arabic following international guidelines. The psychometric properties of the final version of the FACS-Arabic (FACS-A) were tested among 119 patients with different musculoskeletal (MSK) pain disorders. The Cronbach's α for the FACS-A was 0.86. The test-retest reliability, measured with intraclass correlation coefficient, was 0.80. The FACS-A showed positive significant correlations with other psychological patient-reported measures, including the pain catastrophizing scale (PCS) ( This study determined the FACS-A to be a reliable and valid tool for the assessment of the fear-avoidance beliefs in Arabic-speaking individuals with MSK pain disorders. The Arabic version of the fear avoidance component scale is a reliable and valid tool to assess pain fear-avoidance beliefs in individuals with musculoskeletal pain.This tool can be used to assess fear-avoidance beliefs in clinical practice for Arabic-speaking individuals.
