Mental Health First Aid (MHFA) courses are based on evidence of what is best practice mental health first aid to support someone who has a mental health problem or is experiencing a mental health crisis. This evidence has been developed in partnership with the University of Melbourne, through developing Delphi method guidelines that cover a number of mental health problems, crises and in different contexts. All MHFA courses are then evaluated, using rigorous scientific methods, to ensure they are having a positive impact.

These evaluations consistently show that MHFA training is associated with improved knowledge of mental illnesses and their treatments, knowledge of appropriate first aid strategies, and confidence in providing first aid to individuals with mental illness, benefits which are maintained over time. Some studies have also shown improved mental health in those who attend the training, decreases in stigmatising attitudes and increases in the amount and type of support provided to others.
