The Interpersonal Theory of Suicide (Quick Read)

Part of the Topic Index: Suicide Prevention · Clinical Practice

Two major frameworks explain suicide risk not by asking "how depressed," but "does this person belong, feel like a burden, feel trapped, and how fast could thought become action."

Thwarted belongingness + perceived burdensomeness = suicidal desire. Acquired capability (via habituation to pain/fear) is separate and required for a lethal attempt. Perceived burdensomeness has the most consistent research support of the three. Real critics exist — reducing suicide to three factors is a genuine overreach argument worth knowing.

Three phases: pre-motivational (background vulnerability), motivational (defeat and entrapment → ideation), volitional (what turns ideation into behavior — impulsivity, access to means, planning). Impulsivity is a named mechanism here, not a side note.

Camouflaging drives the motivational side (belonging, burden, entrapment). RSD + impulsivity drive the volitional side almost entirely — explaining why autism and ADHD produce risk through genuinely separate mechanisms. See Neurodivergence and Suicide for the full picture.

Ask about belonging, burden, entrapment, and speed-to-action. A client positive on both motivational and volitional questions isn't twice as safe to defer.
