Background/aim: Diabetic foot ulcers (DFUs) cause decreased quality of life due to prolonged hospital stay, loss of workforce, disabilities, psychological trauma, and increased healthcare costs. This study aims to assess the validity and reliability of the Diabetic Foot ScaleShort Form (DFS-SF) for Turkish-speaking individuals with DFUs. Materials and methods: This was a methodological study conducted with 174 Turkish patients with DFUs from March 2020 to December 2020. Translation?back translation was performed for language equivalence and expert opinions were obtained for content validity. The scale?s construct validity was tested with confirmatory factor analysis, exploratory factor analysis, and known-group validity. Cronbach?s alpha was used to evaluate internal consistency. Correlation of the DFS-SF with the SF-36 was used to test criterion validity. The scale was then revised according to the TRIPOD checklist. Results: The content validity index value was 0.93 and Cronbach?s alpha ranged from 0.93 to 0.97. The scale maintained its six-factor structure and the factor loadings ranged from 0.52 to 0.86. The fit indices of the model revealed good validity. The correlations (r = 0.43?0.76, p < 0.001) and known-group comparisons supported the construct validity. Conclusion: The Turkish version of the DFS-SF is a reliable tool for measuring the quality of life of people suffering from DFUs.
