Interprofessional education (IPE) is commonly advocated in policy documentation as a means of enhancing collaboration between heath and social care staff. However, little is known about the effects of this type of education. This paper reports findings from a systematic review which was commissioned to search and begin assessing the quality of the published evidence relating to the effects of IPE on staff involved in the care of adults with mental health problems. Results from this study indicate that there is a current lack of rigorous evidence into the effects of IPE in this field. Conclusions from this work are made in connection to mental health policy and recommendations are offered for strengthening the evaluation of IPE.
