joiner theory of suicide
According to the interpersonal-psychological theory, the desire for death by suicide results from the confluence of two interpersonal states: perceived burdensomeness and thwarted belongingness. While feelings of burdensomeness and low belongingness may instill a desire for suicide, they are not sufficient to ensure that desire will lead to a suicide attempt. Indeed, in order for this to occur, the theory suggests a third element must be present: the acquired ability for lethal self-injury.
