Insights
The Turkish KINDL Epilepsy module demonstrates good psychometric properties for assessing quality of life in children with epilepsy. This epilepsy quality of life scale is a promising tool for clinical use.
Area of Science:
- Pediatric Neurology
- Psychometrics
- Quality of Life Assessment
Background:
- Epilepsy significantly impacts children's quality of life.
- Validated tools are essential for measuring health-related quality of life in pediatric epilepsy.
Purpose of the Study:
- To evaluate the psychometric properties of the Turkish version of the KINDL quality of life scale, epilepsy module.
- To assess the reliability and validity of the KINDL Epilepsy module in a Turkish pediatric sample.
Main Methods:
- Internal consistency, reliability, and construct validity were assessed.
- Exploratory Factor Analysis (EFA) was used to determine sub-dimensions.
- Known groups validity and convergent validity were examined.
Main Results:
- The KINDL Epilepsy module showed acceptable internal consistency (α coefficients 0.55–0.80).
- EFA identified three sub-dimensions: Physical, Mental, and Social Well-being.
- Construct validity was supported by good known groups results and satisfactory convergent validity.
Conclusions:
- The Turkish version of the KINDL Epilepsy module is a reliable and valid instrument.
- This epilepsy quality of life scale is a promising tool for evaluating children with epilepsy in Turkey.
- Further research is needed for global validation of the module.
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 αcoefficients 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.
