Özet
Objective: The Impact of Weight on Quality of Life—Kids is a self-reported weight-related quality of life measure that has been validated for children and adolescents aged between 11 and 19. Impact of Weight on Quality of Life—Kids does not have a Turkish version. The aim of this study was to explore the reliability and validity of the Impact of Weight on Quality of Life—Kids in Turkish. Materials and Methods: The Impact of Weight on Quality of Life—Kids was translated into Turkish using Mapi Research Institute's suggested international translation technique. The psychometric evaluation included test-retest reliability, internal consistency, discriminant validity, concurrent validity, exploratory factor analysis, and confirmatory factor analysis. Results: For the total score, the internal consistency of the scale (Cronbach's alpha coefficient) was 0.93. The item-total score correlation coefficients ranged from 0.178 to 0.785. The testretest coefficients were found to be 0.94 for the total score and the subscales ranged from 0.66 to 0.89 after 2 weeks. Discriminant validity analysis demonstrated that the instrument dif- ferentiated well between the obese and non-obese samples. Five variables were discovered via factor analysis that explained 66.9% of the total variation. The chi-square/degree of freedom ratio value was 3.535, the comparative fit index value was 0.834, and the value of root mean square error of approximation was 0.10, as determined by confirmatory factor analysis. Conclusion: Our results demonstrated the adequate reliability and validity of the Impact of Weight on Quality of Life—Kids, suggesting that this scale is a useful tool for screening Turkish children and adolescents for weight-related quality of life. © 2022, AVES.
