Abstract

The Columbia Suicide Severity Rating Scale (C-SSRS) is considered the gold standard for collecting information on suicidal ideation and behavior by the Food and Drug Administration (FDA) of the United States. To determine the accuracy of the C-SSRS compared to the Beck Scale for Suicidal Ideation (BSS) for collecting suicide attempt history in the schizophrenia population, 202 participants aged 18-40 with schizophrenia spectrum disorders were administered the C-SSRS, followed by the BSS. Medical charts were reviewed to confirm the lifetime history of actual suicide attempts. The BSS had an 83.5% accuracy in reporting single suicide attempts and 81.7% for multiple suicide attempts; while the C-SSRS had 84.1% and 83.9% accuracy respectively. This difference was not statistically significant (p = 0.849). Both the BSS and C-SSRS demonstrated high sensitivity and specificity in collecting suicide attempt history for young patients with psychosis, with no significant differences. Future investigators may choose the scale that is best suited to the level of detail required.
