Designed as a measure of perceptions of collaboration, the original psychometric testing of the Interdisciplinary Education Perception Scale (IEPS) indicated a four-factor solution to this measure, although subsequent research has suggested a three-factor solution may have better fit indices. This study aimed to better understand psychometric properties of the IEPS in a new population, health graduate students in the United States, to determine which sub-scale structure may be a better fit. Additionally this research explores the IEPS through a targeted literature review and content analysis in combination with factor analysis to better understand what constructs are able to be assessed by this measure. Results showed that the three-factor model was the best fitting model for the IEPS, suggesting this structure should be used when looking at graduate-level health students. Results also suggested that the IEPS may be able to be as a measure of perceived professional prestige, for which there is currently no existing measure. The dimension of professional prestige should be explored in further research to create a more robust understanding of its role in collaboration between professions.
