Summary

The goal of this observational validation study is to assess the psychometric properties of the Spanish versions of the Suicide Crisis Inventory-Revised (SCS-2) and the Suicidal Crisis Syndrome Checklist (SCS-C) in adults recently hospitalized for suicidal behavior in Chile. The study aims to determine whether the Spanish versions of the SCS-2 and SCS-C demonstrate adequate internal consistency, construct validity, interrater reliability, and test-retest stability, and whether these tools validly assess imminent suicide risk in a Spanish-speaking psychiatric population. Clinical assessments using the SCS-2 and SCS-C will be compared with established diagnostic and functional measures, including the Mini International Neuropsychiatric Interview (MINI), the Sheehan Disability Scale (SDS), and the Sheehan Suicidality Tracking Scale (S-STS), to evaluate convergent and discriminant validity. Participants will complete the SCS-2 and SCS-C at both admission and discharge from a psychiatric intensive care unit, undergo structured interviews and functional assessments, be evaluated by two independent raters for interrater reliability, and be reassessed within a short time interval to measure test-retest reliability. Follow-up contacts at 7 and 30 days post-discharge will be used to assess suicidal behavior outcomes. This is the first study to culturally adapt and validate these suicide-specific instruments in Latin America.

Suicidal Crisis Syndrome Checklist (SCS-C)

The Suicidal Crisis Syndrome Checklist (SCS-C) is a clinician-rated tool designed to diagnose Suicidal Crisis Syndrome (SCS), a suicide-specific state associated with imminent risk. It includes Criterion A (entrapment)-a required symptom-and Criterion B, which requires at least one symptom from each of four domains: affective disturbance, loss of cognitive control, hyperarousal, and social withdrawal. The checklist offers a structured assessment for identifying acute suicide risk, complementing traditional risk evaluations.

DIAGNOSTIC_TEST

Suicide Crisis Inventory-Revised (SCS-2)

The Suicide Crisis Inventory-Revised (SCS-2) is a 61-item self-report scale developed to assess the severity of Suicidal Crisis Syndrome (SCS), a clinical state associated with imminent suicide risk. Items are rated on a Likert scale and grouped into five empirically derived factors: entrapment, affective disturbance, loss of cognitive control, hyperarousal, and social withdrawal. The SCS-2 has shown strong internal consistency and predictive validity for suicidal behavior within weeks of discharge. It is currently undergoing cultural adaptation and psychometric validation in Spanish for use in high-risk psychiatric populations in Chile.
