[Hungarian adaptation of the Pediatric Quality of Life Inventory™ 3.0 Diabetes Module]. / A Pediatric Quality of Life Inventory™ 3.0 Diabetes Moduljának magyarországi adaptálása.

UNLABELLED: Due to the lack of validated age- and disease-specific instruments, there are limited health-related quality of life measurements in type 1 diabetes youths in Hungary. OBJECTIVE: To culturally adapt the Pediatric Quality of Life Inventory™ 3.0 Diabetes Module. METHOD: Feasibility, internal consistency reliability, reproducibility, convergent, discriminant and concurrent validities were evaluated in 134 type 1 diabetes youths. RESULTS: Low scale-level mean percentage of missing item responses, minimal floor and moderate ceiling effects supported the feasibility. Cronbach α exceeded the internal consistency reliability standard of 0.70. Concordance between the children's and the parents' reports was strong. The instrument differentiated between the quality of life of patients having acceptable and poor metabolic control. Intercorrelations between the Generic Module and Diabetes Module had moderate to large effect sizes. CONCLUSIONS: The results demonstrate the feasibility, reliability and validity of the instrument, but further research should be carried out for generalization for Hungarian population.
