To prepare for the modern collaborative healthcare system, health science academia is charged with educating future professionals to be competent members of the interprofessional team. The purpose of this pilot study was to assess self-efficacy for interprofessional education (IPE) in medical laboratory technology, dental hygiene, and nursing students before and after an IPE session. The specific topic of ethics was the focus of the session. The interprofessional seminar was designed to compare the codes of ethics from each programme through discussion and a case-based approach. The Self-Efficacy for Interprofessional Experiential Learning scale was used to collect quantitative data. A total of 75 participants rated self-efficacy for IPE before and after the educational offering. A paired sample t-test was used to analyse data. Significant results were found in students' pre- and post-test scores that indicated increased levels of self-efficacy related to working as a collaborative team for the benefit of the patient. Overall, there was an increase in participants' self-efficacy after collaborating with students from different health professions programmes. Healthcare students that learn together are more confident in their abilities to implement a team-structured approach, and understand that doing so will foster optimal patient wellbeing.
