Suicidal Ideation

Depression

Suicidal ideation encompasses thoughts about one's own death, from passive wishes to not exist to active plans with intent and method. It is not a symptom to ignore or to dramatize: it requires careful clinical evaluation. Most people with ideation do not act; understanding its nature reduces the risk of dismissing important signals.

Concept origin

The distinction between passive and active ideation, with and without a plan, was systematized by Beck (1979) with the Scale for Suicide Ideation (SSI). Joiner (2005) developed the Interpersonal Theory of Suicide, identifying thwarted belonging and perceived burdensomeness as critical proximal factors.

How it manifests

Therapeutic approach

Risk assessment is the mandatory first step: frequency, intensity, plan, access to means, prior attempts, protective factors. Interventions include reducing access to lethal means, collaborative safety planning, treatment of the underlying condition, and when indicated, urgent referral.
