  2. aPain and Fatigue are single item dimensions so could not be empirically tested using confirmatory factor analysis
  3. bSchool 1 and School 2 are not included in the parent proxy-report version of the PedsQL for young children
  4. cSchool 3 was a single item dimension for children aged 2–5 years since School 1 and School 2 are not included in the PedsQL for those age groups, thus the School Functioning dimension could not be empirically tested using confirmatory factor analysis for age groups 2–3 years and 4–5 years
  5. dSchAbs 1 and SchAbs 2 were not administered for children aged 2–3 years in the LSAC
