ABSTRACT
Purpose: The purpose of this study is to develop a “Multidisciplinary Collaboration Ability Scale (MCAS)” and examine the reliability and validity for medical professionals engaged in cancer care. Method: The first MCAS draft was created, and the content validity and surface validity of the scale were examined for medical professionals. Next, a cross-sectional questionnaire survey was conducted on medical professionals engaged in cancer care who worked in medical institutions. Exploratory factor analysis and known-groups technique were carried out, coefficient α calculated, and concurrent validity examined. This study was conducted with the approval of the research ethics review. Result: Exploratory factor analysis resulted in 33 items of 4 factors (ability to promote discussion, foundational relationship building, self-control, and problem-solving activities). The MCAS score was significantly higher for those who had participated in a multidisciplinary workshop and those who had more years of experience. Coefficient α for the entire scale and for each factor was .80 and above. Examination of concurrent validity showed a moderate correlation. Conclusion: The reliability and validity of MCAS in its development stage were generally verified.
