Introduction: This scoping review aimed to examine 1) types of inter-professional (IPE) interventions using Strosahl’s typology framework, 2) practice outcomes related to healthcare setting and patients using Kirkpatrick’s model of training evaluation, and 3) enablers and challenges related to the effectiveness of IPE interventions specific to the mental healthcare setting in order to guide the development of such future programs.

Methods: This scoping review was conducted in accordance with the methodology of the Joanna Briggs Institute for scoping reviews. Several databases were searched for relevant studies from database inception until December 2023. Articles were included if it 1) involved IPE interventions within mental healthcare, 2) reported practice outcomes related to healthcare setting and patients, and 3) was published in English. Variables of interest included the mode of IPE intervention using Strosahl’s typology, enablers, and challenges related to IPE interventions.

Results: Overall, 16 studies were included. IPE intervention outcomes within healthcare setting related to shifts in practice culture, engagement with family members, and increased collaborations with other inter-professional groups. Reported patient outcomes included clinical improvements (e.g., reduced depression and anxiety, psychotropic drug use, better psychosocial functioning), patient empowerment, satisfaction, and confidence in treatment. The enablers and challenges included resource limitations, inter-professional group and individual participation, and pedagogy.

Discussion: Future efforts in IPE mental healthcare practice can focus on garnering sustained institutional support, identifying and investing in committed faculty, encouraging greater learner participation, and making iterative changes to the IPE program structure to facilitate involvement of inter-professional disciplines for better patient care.
