A Two-day Workshop that is the best one I have found that helps prepare you in case you are needing to do an intervention as a caregiver with a person at risk.
Applied Suicide Intervention Skills Training (ASIST) is for everyone 16 or older—regardless of prior experience—who wants to be able to provide suicide first aid. Shown by major studies to significantly reduce suicidality, the ASIST model teaches effective intervention skills while helping to build suicide prevention networks in the community.
