Columbia-Suicide Severity Rating Scale.

C-SSRS

What it measures

Severity and intensity of suicidal ideation and the type, frequency and lethality of suicidal behavior, across four constructs (severity of ideation, intensity of ideation, behavior, lethality); current and lifetime versions

Length and format

Variable (ideation severity 1-5, intensity sub-items, behavior and lethality subscales); screener and full versions. Yes/no ideation and behavior probes with an ordinal 1-5 ideation-severity scale and a 0-5 lethality scale; not a single summed score - a structured risk classification (clinician-rated/interview)

Language versions

150+ language/country versions (the most-translated suicide-risk instrument); official translations via the Columbia Lighthouse Project
