A Systems Study on Interprofessional Collaboration in Healthcare: Testing the Japanese Version of the Assessment of Interprofessional Team Collaboration Scale II

This study aims to translate and adapt the Assessment of Interprofessional Team Collaboration Scale II (AITCS-II) cross-culturally for effective and systemic use in Japan, to describe floor and ceiling values, and to examine in terms of such criteria as reliability and face and content validity. The AITCS-II was translated from English into Japanese to develop the Japanese version of the Assessment of Interprofessional Team Collaboration Scale II (hereinafter referred to AITCS-II-J). Then, cross-sectional and cross-professional data analyses were carried out to seek evidence of construct validity. Analysis demonstrated good content and face validity. With a Cronbach's alpha coefficient greater than 0.9 (r varied from 0.912 to 0.940), the AITCS-II-J exhibited excellent internal consistency. The AITCS-II-J showed evidence of acceptable validity and reliability; therefore, this measurement system will be useful for informing the enhancement of interprofessional team collaboration within the Japanese acute healthcare context.
