Applied Suicide Intervention Skills (ASIST) is now by far the most widely used suicide intervention skills training in the world, with 3000 registered trainers in Canada, USA, Australia, New Zealand, Norway, Ireland and the UK. 

ASIST is a Living Works Education Suicide Intervention Programme that aims to enable helpers (both lay and professional) to become more willing, ready, and able to recognise and intervene effectively to help persons at risk of suicide.

ASIST is intended as suicide first aid training.

Suicide is a community wide problem and not a mental illness. Suicidal thoughts are understandable, complex and personal, and suicide can be preventedMost people with thoughts of suicide indicate, directly or indirectly, that they want to live. Help seeking is encouraged by open, direct and honest talk about suicide. The best way to identify people with thoughts of suicide is to ask them directly about their thoughts.

Relationships are the context of suicide intervention. Intervention should be the main suicide prevention focus. Co-operation is the essence of intervention. Intervention skills are known, and can be learned.
