Turkish validity and reliability study of Pediatric Quality of Life Inventory (PedsQL) 3.0 cardiac module for 8–18 years old children and parents

This study aimed to evaluate the Turkish validity and reliability of the 8–12- and 13–18-years child and parent forms of the Pediatric Quality of Life Inventory (PedSQL) 3.0 Cardiac Module. This methodological study was conducted in children (8–18 years old) with cardiac disease and their parents. The PedsQL 4.0 were also used to collect data for the parallel form method. Pearson correlation coefficients between the scale and its sub-dimensions were evaluated for construct validity. For construct validity, mean scores of children with cardiac disease and healthy children and their parents were compared. Cronbach's alpha coefficient was calculated to evaluate the internal consistency of the items. In this study, 136 children aged 8–12 years and 135 adolescents aged 13–18 years with cardiac diagnosis and their parents participated. The Cronbach alpha coefficients were found to be above 0.80 for all sub-dimensions and the total scale. Correlations between PedsQL 3.0 Cardiac module and PedsQL 4.0 scores were moderate to highly significant. A significant difference was found between the mean scores of the children with cardiac disease and healthy child and parent forms (p
