Turkish Adaptation and Psychometric Evaluation of the Measure of Processes of Care for Service Providers in Pediatric Care and Rehabilitation

Background/Objectives: Family-centered services (FCSs) are a key approach in pediatric healthcare and rehabilitation that promotes collaboration between service providers and families. The Measure of Processes of Care for Service Providers (MPOC-SP) is widely used to evaluate family-centered services from the provider perspective; however, no validated Turkish version is available. This study aimed to translate and culturally adapt the MPOC-SP into Turkish and to examine its factor structure, internal consistency, test-retest reliability, measurement error, and supplementary model-based construct indices among Turkish-speaking service providers working in pediatric healthcare, disability, and rehabilitation settings.

Methods

The MPOC-SP was translated and culturally adapted following a structured cross-cultural adaptation process. A total of 267 service providers from multiple professional disciplines, institutional settings, and 15 provinces of Türkiye participated in the psychometric evaluation. Internal consistency was assessed using Cronbach's alpha and McDonald's omega. Test-retest reliability was evaluated in 86 participants using ICC(2,1), and measurement error was examined using the standard error of measurement (SEM) and minimal detectable change at the 95% confidence level (MDC95). The hypothesized four-factor structure was evaluated in 267 participants using confirmatory factor analysis based on polychoric correlations and diagonally weighted least squares (DWLS). Composite reliability, average variance extracted, the Fornell-Larcker criterion, and the heterotrait-monotrait ratio were examined as supplementary model-based indices. Institutional-group comparisons were exploratory.
