Cultural adaptation and psychometric validation of the Chinese version of the Assessment of Interprofessional Team Collaboration Scale-II in Taiwan

Taiwan's National Ten-year Long-term Care Plan 2.0 emphasizes interprofessional collaboration (IPC) in home health services. A suitable tool to assess IPC in Taiwan has been lacking. This study developed and validated the Chinese version of the Assessment of Interprofessional Team Collaboration Scale-II (C-AITCS-II), tailored for Taiwan's long-term care field. We used Brislin's back-translation method to ensure cultural and contextual alignment. Four translation experts created the initial tool; 10 gerontology experts refined it through consensus. The C-AITCS-II, comprising three subscales - Partnership, Cooperation, and Coordination-was validated with 201 home health service providers. Results showed strong test-retest reliability (intraclass correlation coefficient = .83) and internal consistency (Cronbach's α = .97). Construct validity was confirmed with factor loadings of .66-.95 and acceptable convergent and discriminant validity. The C-AITCS-II aligns with the original scale and demonstrates strong cultural adaptation, reliability, and validity - offering a valuable tool for assessing IPC in Taiwan.
