At least one in five adults in Northern Ireland may suffer from some form of common mental health disorder in any year.
Research into public sector sickness absence highlighted that stress, depression, mental ill health and fatigue accounted for 23% of lost working days, at a cost of around £5.3m.
In the Health and social wellbeing survey, 19% of the Northern Ireland population aged 16 and above scored four or more on GHQ12, indicating possible psychiatric morbidity.
