Resumen


Background: KIDSCREEN-52, which assesses health related quality of life in adolescents, has been adapted and validated in Chile showing excellent psychometric properties. There is a shorter version of the instrument, whose psychometric properties must be assessed. Aim: To evaluate the psychometric properties of the instrument KIDSCREEN-27 in Chilean adolescents. Material and Methods: A secondary analysis of the database obtained for the adaptation and validation of KIDSCREEN-52. Results: The reliability, calculated through Cronbach's alpha, for the entire instrument (five dimensions) was 0.89. For physical well-being, psychological well-being, autonomy and relationship with parents and peer social support dimensions, scores were higher than 0.75 while for school environment, the score was 0.69. The confirmatory factor analysis showed that the indices obtained to assess the goodness of fit in this study were a ?2 (314) = 10521.4, a Root Mean Square Error of Approximation = 0.064 and a Comparative Fit index = 0.96. KIDSCREEN-27 scores were higher among men in the physical well-being, psychological well-being, autonomy and relationship with parents dimensions and among women in social support and peers and school environment dimensions. Scores were higher in younger age groups. Conclusions: The Chilean version of KIDSCREEN-27 instrument has adequate reliability and validity.
