Reliability and Validity of The Cerebral Palsy Quality of Life Questionnaire in The Turkish Population

Abstract

This study examined the psychometric properties of the Turkish version of the Cerebral Palsy Quality of Life Questionnaire (CP QOL). A total of 149 primary caregivers completed the final version of the CP QOL–Primary Caregivers and the Children Health Questionnaire (CHQ) for children 4–12 years old ( M age = 7.6 yr., SD = 2.5); 58 children with CP ages 9 to 12 years completed the CP QOL–Child and Health-Related Quality of Life Questionnaire for Children (Kid–KINDL) questionnaire. The Gross Motor Function Classification System was also used for the classification of the children with CP. Internal consistency (Cronbach's α) ranged between .63 and .93 for primary caregivers and .61 to .92 for the children's self-reports. Intra-class correlation coefficients ranged between .88 and .97 for primary caregivers and .91 to .98 for children. It was concluded that the Turkish version of CP QOL questionnaire is a reliable and valid tool for assessing QOL in children with CP.
