Abstract

The aim of this research was to evaluate the psychometric properties of the quality of life questionnaire KIDSCREEEN-27 adapted to Chilean children and adolescents. The sample was 1678 participants from schools between 8 and 18 years old. The internal consistency and indicators for construct, discriminante and convergent validity was evaluated. Cronbach alphas for total scale and the domains were higher to .70. The exploratory and confirmatory factorial analysis confirmed the five domains proposed in the theoretical structure. The questionnaire was capable of discriminate by gender, as well as among ages, in different domains. In conclusion, results show that the KIDSCREEN-27 presents acceptable coefficients of reliability and validity, similar to those of the original version. This allows Chilean researchers to have a new instrument to evaluate quality of life, and simultaneously to compare their results with other countries that use this instrument.
