Few studies have examined social work student outcomes after engagement in interprofessional (IP) learning experiences. We examined self-reported attitudes and skills self-efficacy among social work students before and after their engagement in IP Forums. The data comes from social work students who participated in 2016-2018 Fall IP Forums focusing on opioid use disorder. Using the Interprofessional Attitudes Scale (IPAS) and the Interprofessional Collaborative Competency Attainment Scale, revised (ICCAS), we assessed students’ self-reported attitudes (IPAS) and skills self-efficacy (ICCAS) before and after the Fall IP Forums. Paired t-tests identified significant changes in IPAS and ICCAS scores. Students reported increases in their IP attitudes and skills self-efficacy following participation in the IP Forum as measured by pre-IPAS score (n=236, M=4.56, SD=0.29) to post-IPAS score (M=4.68, SD=0.27; t(156)=-5.31, p<.001). Post-ICCAS score also increased (n=48, M=4.26, SD=0.69; t(33)= -5.75, p<.001) from the pre-ICCAS score (M=3.55, SD=0.92). The 2015 Council on Social Work Education Accreditation Standards require that social work students learn how to value and engage in interprofessional teams. Given the self-reported increases in IP attitudes and skills self-efficacy seen in this study, IP Forum participation will help foster greater engagement and contribution to overall IP experiences for social work students.
