Construct and criterion validity of the PedsQL 4.0™ instrument (pediatric quality of life inventory) in Colombia

Abstract

This project aimed at determining the validity of the Pediatric Quality of Life Inventory 4.0 (PedsQL 4.0™) for the measurement of the health-related quality of life (HRQOL) in Colombian children.

Method. Validation study of measurement instruments. the PedsQL4.0TM was applied by convenience sampling to 375 pairs comprises of children and adolescents between 5 and 17 years old and their parents-caregivers, as well as 125 parents-caregivers of children between 2 and 4 years old in five cities of Colombia (Bogota, Medellin, Cali, Barranquilla and Bucaramanga).

Construct validity was assessed through the use of exploratory and confirmatory factor analysis, and criterion validity was assessed by correlations between the PedsQL 4.0™ and the KIDSCREEN-27.
