Psychometric Properties of Compliance and Perceptions of Parents of Children with Cerebral Palsy to Home Program Assessment Questionnaire

Objective: Home program (HP) compliance is a crucial matter for parents of cerebral palsy (CP). A questionnaire is needed to determine the compliance and perceptions of parents of children with CP regarding the HP. The aim is to evaluate the structural validity, reliability, and responsiveness of Compliance and Perceptions of Parents of Children with Cerebral Palsy to Home Program Assessment Questionnaire (CPHP-Q). Methods: Parents of children with CP aged 2-18 years completed CPHP-Q (n=225). Among all participants, 70 individuals were randomly selected for responsiveness, and another 70 individuals were selected for reliability. Psychometric properties were evaluated using the intraclass correlation coefficient (ICC) and Cronbach’s Alpha for reliability, effect size (ES) and standard response mean (SRM) for responsiveness, and factor analysis for validity. Results: In parents with CP, CPHP-Q demonstrated high internal consistency (Cronbach’s alpha=0.96, ICC=0.93). Compliance and Perceptions of Parents of Children with Cerebral Palsy to Home Program Assessment Questionnaire showed significant responsiveness with ES value 1.31 and SRM value 1.29. Kaiser Meyer Olkin (KMO) was found to be significant with a value of 0.82. According to factor analysis, Chi-square/degrees of freedom (CMIN/DF)=2.25, The Root Mean Square Error of Approximation (RMSEA)=0.07, Goodness of Fit Index (GFI)=0.84, and comparative fit index (CFI)=0.93 were found. These values showed that model fit was good. Conclusion: The CPHP-Q is a valid, reliable, and responsive measure for HP adherence of parents of children with CP, and it is useful for determining HP implementation adherence and perceptions of parents but needs validation in other languages.
