First, he talks about a well supported model called Joiner's Model, based on research which shows that people who are most likely to commit suicide have all three of these factors:
- Thwarted belongingness ("I am alone")
- Perceived burdensomeness ("I am a burden")
- Ability to commit suicide ("I am not afraid to die")
Perceived burdensomeness has two components: Liability ("My death is worth more than my life to others") and self-hate ("I hate myself")
Thwarted belongingness also has two components: Loneliness ("I feel disconnected from others") and absence of reciprocal care ("I have no one to turn to and I don't support others")
And finally, capability to commit suicide is predicted by: Lowered fear of death, elevated physical pain tolerance, family history of suicide, clustering/exposure to suicidality, combat exposure, suicide attempts, childhood maltreatment
And another model with the acronym "IS PATH WARM" shows that people who are most likely to commit suicide are likely to have, feel or be:
- I = Ideation
- S = Substance Use
- P = Purposelessness
- A = Anxiety
- T = Trapped
- H = Hopelessness
- W = Withdrawal
- A = Anger
- R = Recklessness
- M = Mood Change
