Cross-validation of the Personality Assessment Inventory "Chronic Suicide Risk Index: S_Chron" in a large sample of offenders. Academic Article uri icon


  • Recently, Sinclair et al. (2016) reported on the development of a new Personality Assessment Inventory (PAI) index designed to identify individuals with histories of multiple suicide attempts (Chronic Suicide Risk Index: S_Chron). We evaluated this new index in a sample of over 1000 criminal offenders who had been administered the PAI as part of a more extensive research project. The S_Chron meaningfully discriminated between those with multiple prior suicide attempts and those with 0-1 attempts, similar to what Sinclair et al. reported. However, it did not demonstrate incremental validity beyond the PAI's Suicidal Ideation scale.
