Pediatric health-related quality of life questionnaires in clinical trials

PURPOSE OF REVIEW: This review summarizes recent studies on the feasibility, reliability and validity of pediatric health-related quality of life questionnaires and gives an overview of recent applications of these measures in pediatrics. RECENT FINDINGS: The often-applied short form of the Child Health Questionnaire (CHQ-PF28) provides reliable physical and psychosocial summary measures, but reliable estimates for each scale require the longer version (CHQ-PF50). In addition to this questionnaire, the Pediatric Quality of Life Inventory is another reliable and valid measure. The TNO-AZL Preschool Children Quality of Life questionnaire is a feasible and reliable measure for preschool children. Generally, generic questionnaires are less sensitive to the impact of specific diseases than are disease-specific questionnaires. Parent and self-reports provide different outlooks on quality of life, which complement each other. SUMMARY: There are several feasible, reliable and validated pediatric quality of life questionnaires that can be used in clinical trials. These include generic and disease-specific questionnaires and health profile measures, as well as preference-based measures in pediatric settings. Generally, a combination of these types of questionnaires would be the most appropriate approach. Moreover, a combination of parent and self-reports should be applied. Appropriate selection of outcome measures will enhance the quality of pediatric studies and the ability to assess treatment effects in clinical trials.
