Latin American Testing of the Inventory for Risk in Suicidal Crisis Syndrome (LATIR-SCS)

Conditions studied: Suicidal Crisis

In brief

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.
