Transcultural adaptation of the Malayalam version of the diabetic foot ulcer scale-short form

Abstract

Introduction: Among Diabetes Mellitus (DM) patients, Diabetic Foot Ulcer (DFU) is the most prevalent complication that affects the patients' quality of life (QoL). The present study aims to translate, validate, and test the reliability of the Diabetic Foot Ulcer Scale-Short Form (DFS-SF) in the Malayalam language. Methodology: The DFS-SF questionnaire was translated Malayalam language using the Mapi Research Trust translation guidelines. The content validity index (CVI) and reliability was assessed for the translated DFS-SF Malayalam questionnaire. The construct validity was assessed using the EQ-5D and VAS. Results: The average CVI score for the DFS-SF Malayalam questionnaire was 1.00. The reliability of the DFS-SF Malayalam version questionnaire has shown an excellent Cronbach's alpha score. There is a positive correlation between dependence and VAS (r = 0.538, p = 0.014), bothered by ulcer care and VAS (r = 0.494, p = 0.027). Conclusion: The newly translated DFS-SF Malayalam questionnaire is valid and reliable for assessing the QoL among DFUs in Malayalam patients.
