PedsQL GCS was designed to measure health-related quality of life in pediatric participants and adolescents (2 to 18 years of age). It encompasses 4 dimensions of functioning (physical [8 items], emotional [5 items], social [5 items], school [3 items]). Age groups were: Toddler (2-4 years), Young pediatric (5-7 years), Pediatric (8-12 years), and Teens (13-18 years). Depending on the participant's age, the questionnaire may be completed by parent/caregiver as appropriate. For the Toddler group, the PedsQL GCS consisted of 21 items, using a 5-point Likert scale (0 to 4); for all other groups, the PedsQL GCS consisted of 23 items, with a 3-point Likert scale (0, 2, 4) for the young pediatric, and a 5-point Likert scale for the pediatric and teens groups. Scores are transformed on a scale from 0 to 100 where 0=100, 1=75, 2=50, 3=25, and 4=0. Higher scores indicate improved quality of life.
