About this study
Official title: Suicidal Crisis Syndrome and the Suicide Crisis Inventory-Revised (SCS-2): Psychometric Properties of the Spanish Version
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.
Read the detailed description
This is a three-phase, observational psychometric validation study of the Spanish versions of the Suicide Crisis Inventory-Revised (SCS-2) and the Suicidal Crisis Syndrome Checklist (SCS-C), administered to adult psychiatric inpatients hospitalized for recent suicidal behavior at the Complejo Asistencial Dr. Sótero del Río (CASR), Chile. The study follows established guidelines for the translation, cultural adaptation, and validation of health-related instruments. Phase one involves linguistic validation through forward-backward translation by bilingual experts. Phase two consists of a pilot test of the pre-final versions with 10 patients to assess item clarity and cultural relevance. Phase three uses a prospective cohort design with 60 participants to evaluate psychometric properties. Assessments are conducted at admission and discharge and include the SCS-2 and SCS-C (Spanish versions), the Mini International Neuropsychiatric Interview (MINI), the Sheehan Disability Scale (SDS), and the Sheehan Suicidality Tracking Scale (S-STS). A subset of participants will complete the SCS-2 twice within a short time interval to assess test-retest reliability and will be evaluated by two independent raters for interrater reliability. Follow-up at 7 and 30 days post-discharge includes phone interviews and chart reviews to assess suicidal behavior outcomes. A sample size of 60 was selected based on prior studies to ensure sufficient power to evaluate internal consistency (Cronbach's α ≥ 0.80), factor structure, and interrater reliability (Cohen's κ ≥ 0.60). Statistical analyses will include Cronbach's alpha and item-total correlations for internal consistency, exploratory and confirmatory factor analysis (EFA/CFA) for construct validity, Pearson or Spearman correlations with SDS and S-STS for convergent validity, point-biserial correlations with MINI diagnoses for discriminant validity, ICC and Cohen's kappa for interrater reliability, ICC for test-retest reliability, and ROC curve analysis for predictive validity. Data will be collected electronically via Qualtrics, which includes built-in logic checks and skip patterns. Source data verification will be performed through cross-checks with clinical records and dual entry of outcome events. A detailed data dictionary outlines all variables, coding schemes, and response formats. Procedures are standardized through SOPs covering recruitment, consent, data collection, follow-up, and confidentiality. Missing data will be addressed through multiple imputation and sensitivity analyses. Data monitoring is performed internally, and adverse events or protocol deviations are reported to the Institutional Ethics Committee. This is the first study to validate the SCS-2 and SCS-C in a Spanish-speaking Latin American population and is expected to contribute to scalable, evidence-based suicide risk assessments in acute psychiatric settings.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Suicidal Crisis Syndrome Checklist (SCS-C)Diagnostic test
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.
Suicide Crisis Inventory-Revised (SCS-2)Diagnostic test
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.

|---|---|---|
| SCS+ Cohort | Definition: Patients who meet the diagnostic criteria for Suicidal Crisis Syndrome using the clinician-administered SCS-C. Receives: Diagnostic Test: Suicidal Crisis Syndrome Checklist (SCS-C); Diagnostic Test: Suicide Crisis Inventory-Revised (SCS-2) | |
| SCS- Cohort | Definition: Patients hospitalized for suicidal behavior who do not meet diagnostic criteria for SCS on the SCS-C. Receives: Diagnostic Test: Suicidal Crisis Syndrome Checklist (SCS-C); Diagnostic Test: Suicide Crisis Inventory-Revised (SCS-2) |

What is this clinical trial studying?
An observational study of Suicidal Crisis, run by University Diego Portales at 1 site in Chile.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 11 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: looking for participants now, as of the sponsor's last update on 19 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Chile. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?
Contact Francisco Villalón, M.D (+56988996001, villalon.fj@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Suicidal Event Within 30 Days Post-Discharge (time frame: 30 days post-discharge). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Sep 2025.
