Abstract :Objective: This study aimed to evaluate the validity and reliability of the Turkish version of the Wound-QoL-14 questionnaire. Methods: This methodological study included 141 patients with chronic wounds (mean age 63.52±13.94 years; 57% male) treated in a university hospital in Istanbul between March 2022 and April 2023. Content validity was assessed using both expert panel and patient feedback. Internal consistency was assessed with Cronbach’s alpha, and item-total correlations were analyzed using Pearson correlation coefficient. Test–retest reliability was evaluated in 35 patients after one week interval. Convergent validity was tested using the SF-12 Health Survey. Construct validity was assessed through confirmatory factor analysis (CFA). Results: Based on the Davis method, the item-level content validity indices ranged from 0.90 to 1.00. Cronbach’s alpha coefficients for scale items ranged from 0.76 to 0.97, and item–total correlations ranged from 0.42 to 0.78. The test–retest intraclass correlation coefficient was 0.95. Wound-QoL total scores showed a significant negative correlation with SF-12 sub-dimensions (r = -0.284 to -0.718). CFA confirmed the four-factor structure (body, psyche, everyday life, and a separate item 5) with factor loadings ranging from 0.67 to 0.93. Conclusion: The Turkish version of the Wound-QoL-14 is a valid and reliable instrument for assessing wound-related quality of life in patients with chronic wounds.
