Psychometric Properties of the Iranian-Children Participation Questionnaire (I-CPQ) When Used with Parents of Preschool Children with Cerebral Palsy

ABSTRACT

The purpose of the study was to establish the psychometric properties of the Iranian-Children Participation Questionnaire (I-CPQ) among parents (n = 120) of preschool children with cerebral palsy. The mean age of the preschool children was 5.1 years old. The confirmatory factor analysis was conducted in two stages, and the values of all goodness of fit tests reached an acceptable level (greater than 0.9), and achieved an acceptable root mean square error of approximation model fit value of 0.05. The results of convergent validity with the Vineland Adaptive Behavior Scale for all subtests were significant. Internal consistency was acceptable to excellent (α: 0.66–0.85), and test–retest reliability was excellent (ICC: 0.92–0.98). We concluded that the I-CPQ demonstrated good psychometric properties and utility for assessing participation of Iranian preschool children with cerebral palsy.
