Validity evidence and use of the IPEC Competency Self-Assessment, Version 3.

To guide interprofessional education (IPE), a variety of frameworks have been suggested for defining competency in interprofessional practice, but competency-based assessment remains challenging. One self-report measure developed to facilitate competency-based assessment in IPE is the IPEC Competency Self-Assessment. It was originally described as a 42-item measure constructed on the four domains defined by the Interprofessional Education Collaborative (IPEC) Expert Panel. Response data, however, identified only two factors labeled and . In this study, we tested a revised 19-item, two-factor scale based on these prior findings with a new sample ( = 608) and found good model fit with three items not loading on either factor. This led to a 16-item instrument, which was then tested with an additional sample ( = 676). Internal consistency was high, and scores for both subscales showed variance based on prior healthcare experience. The interprofessional interaction subscale was primarily comprised of items from the Teams and Teamwork domain, with one item each based on competencies from the Interprofessional Communication and Values/Ethics domains; and scores varied by year of enrollment. The interprofessional values subscale was comprised solely of items from the Values/Ethics domain. Scores for both subscales were strongly correlated with scores from the Interprofessional Socialization and Valuing Scale. This study further establishes the validity, reliability, and usability of an assessment tool based on interprofessional competency. The findings also suggest the constructs underlying the subscales may be affected differently by experience and training. Additional study using longitudinal data is needed to test this hypothesis.
