Validation of Persian caregivers' report of quality of life questionnaire for adolescents with cerebral palsy

Background/Aims: There is no tool in Persian to examine quality of life for adolescents with cerebral palsy based on their specific conditions. Therefore, the purpose of this study was to assess the psychometric properties of the Persian version of the caregivers' report of the Quality of Life questionnaire for adolescents with cerebral palsy (CP QOL). Methods: In this psychometric measurement study, the CP QOL (caregivers' report) was translated into Persian, and then its content validity, and construct validity were examined. A convenience sample of subjects including 82 parents of adolescents with cerebral palsy (13-18 years) were recruited for this study. Then, the relationship between the participants' quality of life and their level of gross motor and hand function was assessed. Findings: Internal consistency for all the questions of the questionnaire were high (0.78-0.92). There was also a significant and weak correlation between all domains of quality of life and the adolescents' gross motor function and manual abilities. Conclusions: The Persian version of the caregivers' report of the CP QOL-Teen has acceptable content validity. It is a useful tool for evaluating the quality of life of adolescents with cerebral palsy.
