SALUM, Giovanni Abrahão et al. Youth Quality of Life Instrument-Research version (YQOL-R): psychometric properties in a community sample. J. Pediatr. (Rio J.) [online]. 2012, vol.88, n.5, pp.443-448. ISSN 0021-7557.

OBJECTIVE: To test some psychometric properties of the Brazilian-Portuguese version of the Youth Quality of Life Instrument-Research (YQOL-R) in a community sample of Brazilian adolescents. METHODS: This is a cross-sectional community study conducted in six schools of the catchment area of a family health unit. From an original population of 2,754 students from 10 to 17 years old, we randomly selected 419 to answer the Brazilian-Portuguese version of the YQOL-R. We tested reliability, known group differences (using anxiety symptoms and bullying involvement), and factor structure. RESULTS: The YQOL-R showed a good internal consistency and had an adequate and expected known group differences with both bullying and anxiety. The factor structure of the conceptual model was partially supported by our analysis. CONCLUSIONS: The Brazilian-Portuguese version of the YQOL-R showed sufficiently good psychometric properties. Further studies are needed in order to better investigate alternative configurations of the factor structure.
