Research and evaluation have been integral to the Mental Health First Aid programme since its inception, led by co-founder Professor Anthony Jorm at the University of Melbourne.

In Ireland, a 2022 study conducted by the University of Limerick evaluated the long-term impact of Mental Health First Aid training. The findings confirmed that the programme helps improve participants’ knowledge, confidence, and supportive behaviours when responding to mental health difficulties. The study also identified key factors that can influence outcomes, including stigma, access to mental health services, and the availability of social support. It emphasised the importance of promoting inclusive and equitable environments to enable the effective application of Mental Health First Aid skills.
