Objective: To validate the quality of life questionnaire (QOL) KIDSCREEN-27 in the metropolitan area of Medellín (Colombia). Materials and methods: Validation of a scale of quality of life for children and adolescents aged 8 to 18, healthy and with acute or chronic diseases. We evaluated the construct validity and content, internal consistency, interobserver and intraobserver reliability and sensitivity to change. It surveyed 161 healthy children and adolescents from 3 educational institutions, and 160 ill children and adolescents, 81 with a disease that lasted less than 3 months and 79 with a disease that lasted more than 3 months, inpatients or outpatients from 3 health institutions, 2 public and 1 private 2. Results: QOL in all dimensions was lower in ill children and adolescents and even lower in inpatients. It was also lower in boys than in girls, whereas it was similar for adolescents of both genders. For construct validity the means of each of the groups were different in all dimensions. In the exploratory factor analysis there were 6 categories, validated in the confirmatory factor analysis. Internal consistency was greater than 0.7 in all dimensions. In all domains the intraclass correlation coefficient was above 0.87 in the interobserver reliability and greater than 0.8 in the intraobserver reliability. Conclusion: The KIDSCREEN-27 can be used in children and adolescent population of the metropolitan area of Medellin. It showed adequate psychometric properties of reliability and validity.
