A Validity Study of the Interprofessional Collaborative Competency Attainment Survey: An Interprofessional Collaborative Competency Measure

In health care, there is a shift toward competency assessment, including in interprofessional collaboration and education. The Interprofessional Collaborative Competency Attainment Survey (ICCAS) has been designed to assess self-reported change in interprofessional competency.The current study collects validity evidence for the ICCAS by replicating and expanding previous research, examining internal structure, item functioning, concurrent validity, response process, and consequential validity, including theoretical interpretation of the instrument's application and outcomes.The ICCAS shows good reliability, a single-factor structure, adequate item discrimination, and a moderate concurrent validity. Insight was gained to response process and potential consequences that lend caution to the interpretation of ICCAS results dependent on learner populations.The ICCAS has shown stability, making it a potentially useful instrument in assessing self-reported competency but one that should be applied over multiple time points with an awareness of the specific characteristics and knowledge of the sample.
