What questions/factors should you look at to determine whether your procedure/policy in respect of MHFAs is or isn’t working?

It really depends on what your measure of success is! We would suggest regular wellbeing surveys – if the results of wellbeing surveys suggest that the culture is becoming more open, more psychologically safe, if people are asking for help or referring colleagues to MHFAs as a safe and effective pair of hands – these would be strong indicators of success.
