PURPOSE: The Measure of Processes of Care for Service Providers (MPOC-SP) is a valid and reliable instrument to measure the professionals' perception of the extent to which they apply the principles of family-centered services in care for children with disabilities. This study aimed to evaluate the validity and reliability of the Korean translation of the MPOC-SP (Korean MPOC-SP). METHODS: The Korean MPOC-SP was completed by 132 rehabilitation service providers in 5 provinces in South Korea. Analyses for internal consistency, construct validity, and test-retest reliability were performed. RESULTS: The estimates of internal consistency (Cronbach's alpha) of the four scales of the Korean MPOC-SP ranged from 0.67 to 0.92. All the scales correlated highly with the other scales (r ranging from 0.61 to 0.77). In addition, all the items exhibited high item-total correlations (rs ranging from 0.40 to 0.83). Three scales had moderate to good reliability with ICCs ranging from 0.57 to 0.78; the 'providing general information (PGI)' scale showed low reliability (ICC 0.22). CONCLUSION: The Korean MPOC-SP can be considered a valid instrument for group-level research purposes with acceptable internal consistency, but caution is warranted regarding the low test-retest reliability of the PGI scale.
