Family support and education is a core component of the Ontario Early Psychosis Intervention Program Standards, released in 2011. However, feedback from key informant surveys of Ontario early psychosis intervention (EPI) programs indicated that it can be challenging for programs to implement. The present project responded to an Applied Health Research Question posed by the Early Psychosis Intervention Ontario Network. The network was interested in learning about the barriers and facilitators to implementing family support experienced in other settings to order to inform Ontario EPI program efforts to meet the Program Standards.
