To examine test-retest reliability and construct validity of the Scandinavian version of the caregiver priorities and child health index of life with disabilities (CPCHILD) questionnaire for children with cerebral palsy (CP).
Families were recruited in Sweden and Norway and stratified according to the gross motor function classification system levels I-V for children born 2000-2011, mean age 7.9 (SD 3.2).

Intraclass correlation coefficient was used to estimate test-retest reliability (n?=?64), and Cronbach's alpha was calculated as an indicator of internal consistency.
The questionnaire showed construct validity and the ability to discriminate between levels of gross motor function for the total score and all domain scores (p?
