Validation of the French version of the Caregivers’ Priorities and Child Health Index of Life with Disabilities questionnaire

Abstract

IntroductionThe Caregivers’ Priorities and Child Health Index of Life with Disabilities (CPCHILD) is a questionnaire that measures the health-related quality of life (HRQL) of children with cerebral palsy (CP). Though measuring HRQL is challenging in these children, it is a valuable help for medical decision-making. There is no questionnaire to assess HRQL in French-speaking children with severe CP. ObjectiveTo translate and adapt transculturally the CPCHILD questionnaire into French (CPCHILD-FV). Material and methodsThe CPCHILD was translated from English into French by forward and backward translation by independents translators. The questionnaire was then tested on 32 caregivers of patients with CP classified as GMFCS IV or V, remarks of caregivers were analyzed by an expert committee and, if necessary, modifications were performed. Internal consistency of the CPCHILD-FV was assessed using a sample of 32 parents or caregivers and test-retest reliability was assessed on a random sample of 10 patients. ResultsThe translation and transcultural process resulted in a French version of the CPCHILD. Some items of the CPCHILD required careful discussion to ensure that items had the same meaning as in the original. Internal consistencies were over 0.70 for each domain except for health, and 0.97 for the total scores. The ICC for the test-retest reliability of the CHILD-FV total score was 0.98 (95% CI: 0.93–0.99) and ranged from 0.59 to 0.99 for the domains. ConclusionThe translation and cross-cultural adaptation of the CPCHILD questionnaire provides a French version than can measure the HRQL of children with severe CP. Level of evidenceIV; prospective study without control group.
