Background. The purpose of this study was to investigate the validity and reliability of the Turkish versions of the Measure of Processes of Care, MPOC-56 and MPOC-20, in children with disability aged 5-17 years.

Methods. A total of 290 parents of children with disability due to various disorders were evaluated with the MPOC-56 and MPOC-20. Internal consistency was determined with Cronbach`s alpha, and test-retest reliability with the intraclass correlation coefficient (ICC). Confirmatory factor analysis was performed to investigate the factor structure of the Turkish MPOC-56 and -20.

Results. Cronbach`s alpha values for the MPOC-56 and MPOC-20 ranged between 0.84-0.97 and 0.87-0.92, respectively. Test-retest ICC values were 0.96-0.99 for MPOC-56 and 0.94-0.98 for MPOC-20. The correlations of the subscale scores of MPOC- 56 and MPOC-20 were shown to be at very good to excellent levels for reliability. Factor structure for MPOC-20 and MPOC-56 were found to be acceptable.

Conclusions. This study has shown that the Turkish versions of MPOC-56 and MPOC-20 are valid, reliable, and applicable for the evaluation of parents` experiences of processes of care for children with disability aged 5-17 years.
