The Interpersonal Theory of Suicide (Quick Read)

Part of the Topic Index: Suicide Prevention · Clinical Practice

Two major frameworks explain suicide risk by asking "does this person belong, feel like a burden, feel trapped, and how fast could thought become action" rather than "how depressed."

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 an 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.

Camouflaging drives the motivational side (belonging, burden, entrapment). RSD + impulsivity drive the volitional side almost entirely, explaining why autism and ADHD produce risk through 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.
