Organizing collaborative care in hospitals can increase healthcare quality and patient safety. As a validated instrument, the Care Process Self-Evaluation Tool (CPSET) has been internationally utilized to measure the quality of care process organization from the perspective of interprofessional teams. This study aimed to evaluate the psychometric properties of the Korean version of the modified four-factor CPSET with cultural adaptation. Cross-sectional survey design was employed with 350 healthcare professionals (208 in 2016 and 142 in 2024) to assess construct validity through confirmatory factor analyses (CFA), convergent, and discriminant validity with average variance extracted, composite reliability, and interfactor correlations, and concurrent validity by Pearson's correlation between CPSET and Teamwork Perceptions Questionnaire (TPQ) scores. Reliability was assessed using Cronbach's alpha. In total, 345 participants completed the Korean CPSET. CFA showed acceptable fit (SRMR = 0.061 and CFI = 0.926), except for the RMSEA showing mediocre fit (RMSEA = 0.091). Convergent and discriminant validity was supported. Significant correlation was found between CPSET and TPQ scores (r = 0.67, p < 0.001). Cronbach's alpha of the scale was 0.98. The findings indicate that the Korean CPSET is valid and reliable, making it a valuable tool to assess the quality of collaborative care organization and guide quality improvement efforts in Korean hospitals.
