title: OC19 - Measuring feasibility, reliability and validity of the Greek version of PedsQL cardiac module.
abstract: Theme: Cardiology Introduction: Measuring quality of life (QoL) in children and adolescents with congenital heart disease (CHD) is of great clinical importance.
  
  
  OBJECTIVE
  The aim of the study was: (a) to adapt the PedsQL Cardiac Module for children aged two to 18 years with CHD in a sample of the Greek population; (b) to determine its reliability and validity.
  
  
  METHODS
  Forward and backward translation methodology was used. Parents and children completed the instrument during: (a) hospitalization and (b) visits in the paediatric cardiology outpatient department. Cross-informant variance between children and parents was thoroughly assessed.
  
  
  RESULTS
  Missing item responses did not exceed 5%. All internal consistency reliability coefficients for the inventory exceeded the minimum standards for group comparisons, over 0.75. Hypothesized correlations between cardiac module and core scales were statistically significant, (p<0.05). Agreement between children and parents was relatively high. Pilot study results will be additionally presented.
  
  
  CONCLUSIONS
  The findings support the feasibility, reliability and validity of the Greek translation of the PedsQL Cardiac Module in children with congenital heart defect (CHD).
