Background: Reported rates of mental illness continue to climb amongst young Australians. In a family environment the carers of these young people play a highly influential role in their recovery process, however this responsibility can also have significant emotional, financial and health impacts on carers. Methods: This paper details the findings of an evaluation project examining the impact and effectiveness of a newly developed and implemented Family Peer Support Work model. Results: Benefits were found which included: family care-givers receiving emotional support and empathy; reduced stress, loneliness, isolation and stigma; bridging between the family and the clinical care team; helping families to navigate through the complexities of the care system; and connecting families to other services. Conclusions: Clarity on role definition for the FPSWs evolved over the course of implementation along with a clearer articulation of the model of care and emergent knowledge on useful elements of training, ongoing professional development, mentoring and wellbeing.
