Spanish Suicide Crisis Inventory and Checklist for hospitalized adults in Chile

Suicidal Crisis Syndrome and the Suicide Crisis Inventory-Revised (SCS-2): Psychometric Properties of the Spanish Version

This project tests Spanish versions of two questionnaires (SCS-2 and SCS-C) to see if they can help identify imminent suicide risk in adults recently hospitalized for suicidal behavior.

Quick facts

• Study type: Observational
• Enrollment: 60 (estimated)
• Ages: 18 Years and up
• Sex: All
• Sponsor: University Diego Portales (Academic / other)
• Locations: 1 site (Santiago, Santiago Metropolitan)
• Trial ID: NCT07103850 on ClinicalTrials.gov

What this trial studies

This observational validation project translates and culturally adapts the SCS-2 and SCS-C into Spanish, pilots the items with a small group, then prospectively enrolls 60 adult psychiatric inpatients hospitalized for recent suicidal behavior at Complejo Asistencial Dr. Sótero del Río in Santiago. Participants complete the instruments at admission and discharge, and a subset repeats measures for test-retest and interrater reliability. The instruments' internal consistency and construct validity will be compared with established tools (MINI, Sheehan Disability Scale, and Sheehan Suicidality Tracking Scale), and outcomes at 7 and 30 days post-discharge will be tracked by phone and chart review. The study follows standard forward-backward translation, pilot testing, and psychometric analysis methods used for validating clinical questionnaires.

Who should consider this trial

Good fit: Adults (age ≥18) hospitalized at the Complejo Asistencial Dr. Sótero del Río UHCIP for a recent suicidal event who are fluent in Spanish, able to consent, and judged competent by their treating psychiatrist.

Not a fit: Patients with severe psychotic symptoms, altered consciousness (e.g., delirium), severe agitation needing mechanical restraint, significant cognitive impairment, or non-Spanish speakers are unlikely to benefit from these instruments as tested here.

Why it matters

Potential benefit: If successful, these Spanish tools could help clinicians detect imminent suicide risk more reliably and inform safer discharge planning.

How similar studies have performed: Related versions of the Suicide Crisis Inventory and checklist have shown promising psychometric results in other populations, but Spanish validation in Chilean inpatient settings is limited and this application is relatively novel.
