TRANSLATION, CROSS-CULTURAL ADAPTATION, AND PSYCHOMETRIC EVALUATION OF THE BOSNIA AND HERZEGOVINA VERSION OF THE FOOT AND ANKLE OUTCOME SCORE IN PATIENTS WITH ANKLE SPRAIN: A CROSS-SECTIONAL STUDY

Abstract

Objectives: To translate, adapt, and evaluate the psychometric properties of the Bosnia and Herzegovina version of the Foot and Ankle Outcome Score (BH-FAOS) in patients with ankle sprain.

Methods: In this cross-sectional study, 55 patients with ankle sprains were included. Four psychometric measures were assessed: construct validity (correlation of FAOS and Short Form Quality of Life Questionaire – SF-12), content validity (the patient’s perception of the importance of FAOS questions), reliability (test-retest and internal consistency, Bland-Altman analysis), and responsiveness (after physical therapy intervention).

Results: Satisfactory construct validity was determined. All subscales of FAOS were in moderate correlation (r > 0.3) with the physical and mental health components of the SF-12 (r>0.30). All FAOS subscales demonstrated excellent reliability [Interclass Correlation Coefficient (ICC) values >0.90; Cronbach’s alpha values ≥0.98].

Conclusions: The BH-FAOS is a reliable and valid instrument for assessing outcomes in patients with ankle sprains. The acceptable reliability and construct validity make it suitable for research and clinical purposes. Future studies are needed to establish psychometric properties for patients with different foot and ankle problems.
