Psychometric Properties of the Turkish Version of the Epilepsy Module of the KINDL Quality of Life Scale

Introduction: This study aims to present the psychometric properties of the Turkish version of the KINDLE quality of life scale, epilepsy module. Method: The psychometric properties of the KINDL Epilepsy module were evaluated from the aspect of internal consistency, reliability, and construct validity on an inpatient sample of 159 Turkish children (mean age 10.84 +/- 2.77 years) who had epilepsy. Results: The KINDL Epilepsy module (36 items) showed acceptable a coefficients ranging from 0.80 (social well-being) to 0.55 (treatment) for each domain. EFA suggested three sub-dimensions that we named as Physical, Mental and Social Well-being sub-dimensions. Root Mean Square Error of Approximation was found as 0.053, and Comparative Fit Index was 0.95. Good known groups results supported the construct validity of the instrument. Correlations between the income perception, family support and Duration of Epilepsy and the domains of its Epilepsy module were significantly high, indicating a satisfactory convergent validity. Conclusion: The Turkish version of the KINDL Epilepsy module showed module is a promising tool in this study. However, further research on the versions of the module in other languages is needed for its global use.
