This study aims to compare generic measures of HRQoL obtained with the KIDSCREEN-27 into subgroups of adolescents from different contexts including subgroup of outpatient treatment for mental disorders and subgroups of students from regions with low and high human development index in the direction of analyzing the discriminant properties of the instrument and its utility to monitor health outcomes in adolescents. Descriptive statistics are presented by group and gender. The statistical analyses aimed to check the reliability, convergent validity between self-report and proxy versions and discriminant validity between clinical and students contexts using KIDCREEN- 27 questionnaires. Most assumptions about the reliability, convergent and discriminant validity of the instrument KIDSCREEN-27 were established. This research highlighted lower scores of HRQOL in adolescents with mental illness in four of five dimensions, with an effect size ranging from 0.25 for Physical Well-Being to 0.46 for Autonomy & Parents. The results were acceptable, but the findings in this study were more modest than those obtained in the original validation of the instrument.
