Samenvatting

Discrepancy between self-reports and parent-proxy reports of adolescent health-related quality of life
(HRQoL) has been repeatedly acknowledged in the literature as the proxy problem. However, little is known about
the extent and direction of this discrepancy. The purpose of this study is to explore to what extent and in what
direction HRQoL self-reports of adolescents with chronic conditions and those of their parents differ.
