Aim: To evaluate the correlation between domains for the quality of life of children with cerebral palsy from the CP QoL Child-application and their parents. Method: This is a descriptive and cross-sectional study, conducted in two reference institutions in the city of Fortaleza, and involved one hundred parents of children suffering from cerebral palsy. Data collection occurred through the application of the Cerebral Palsy scale, Quality of Children. Results: We identified a statistically significant moderate correlation between the family and friends' domain and the domain's collective activity (r=0.5145), communication (r=0.2585) and child health (r=0.3277). We also noticed a statistically significant correlation of moderate and weak, between the collective activity domain and the domain of child health (r=0.4669) and special equipment (r=0.2120), respectively. Conclusion: The family and friends domain directly affects others, requiring early intervention in this influential aspect, in order to achieve an improved quality of life for these children.
