Abstract Background The KINDL questionnaire is frequently used to evaluate quality of life QOL and the impacts of health conditions on children s everyday living. The objectives of this study were to assess the reproducibility and construct validity of the Serbian KINDL for QOL assessments in healthy children and adolescents. Methods Five hundred and sixty-four healthy children and adolescents completed the KINDL. Reproducibility was analyzed using the intraclass correlation coefficient ICC . Confirmatory factor analysis CFA was performed to assess the structure of the KINDL construct validity. Results The intraclass correlation coefficients ranged from to for the subscales and total score. A second order CFA model as originally hypothesized was tested items 24 primary factors six subscales and one secondary factor QOL . The fit indexes derived from a CFA failed to yield appropriate fit between the data and the hypothesized model. Conclusion Majority of the subscales and total KINDL possess appropriate reproducibility for group comparisons. However a CFA failed to confirm the structure
