ABSTRACT
OBJECTIVE: This study was conducted to determine the construct validity and reliability of the Children Participation Assessment Scale in activities outside of School-Child version (CPAS-C) in 6-12-year-old children with physical disabilities (PDs). MATERIALS & METHODS: In this methodological study, participants were 100 children with PDs, recruited from a school for exceptional children with physical-motor disabilities and 100 normally developing children. For assessing the test-retest reliability (ICC), 40 children with PDs completed CPAS-C within a two-week interval, and for assessing the internal consistency (Cronbach's alpha) and construct validity, 100 children with PDs separately completed the Vinland Adaptive Behavioral Scale (VABS) and CPAS-C. RESULT: The majority of participants were children with CP, among whom the highest and lowest ratios were related to diplegia (32%) and dystonia (1%), respectively. The results showed that CPAS-C had acceptable reliability (ICC: 0.6-0.99). Cronbach's α score was between weak to moderate (α = 0.25-0.75). The difference in the score of participation between the two groups (normally developing children and children with physical disabilities) was significant in all areas (P<0.001). CONCLUSION: The CPAS-C had acceptable psychometric properties; it can be used as a valid and reliable tool for assessing the participation of 6-12-year-old children with PDs in school activities.
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.
