| contents | Psychometric validation of the Columbia-Suicide Severity rating scale in Spanish-speaking adolescents Daniel Serrani Azcurra Medicina cut Columbia off scores adolescents psychometric validation Introduction: Adolescent suicide is a major public health issue, and early and accurate detection is of great concern. There are many reliable instruments for this purpose, such as the Columbia-Suicide severity rating scale (C-SSRS), but no validation exists for Spanish speaking Latin American adolescents. Objetive: To assess psychometric properties and cut-off scores of the C-SSRS in Spanish speaking adolescents. Methods: Exploratory assessment with principal component analysis (PCA) and Varimax rotation, and confirmatory analysis (CFA) were performed on two groups with 782 and 834 participants respectively (N=1616). Mean age was 24.8 years. A Receiver operator analysis was applied to distinguish between control and suicide-risk subgroups adolescents. Results: Promax rotation yielded two 10-items factors, for suicide ideation and behavior respectively. C-SSRS was positively correlated with other suicide risk scales, such as Beck Depression Inventory-II, Suicidal Behaviors Questionnaire-Revised, or PHQ-9. Confirmatory factor analysis yielded a two-factor solution as the best goodness of fit model. C-SSRS showed adequate ability to detect suicide risk group with positive predictive value of 68.3%. ROC analyses showed cutoff scores of ≥ 6 and ≥ 4 for suicide ideation and behavior scales respectively Conclusion: This research offers data supporting psychometric validity and reliability of C-SSRS in nonclinical Spanish-speaking students. Added benefits are flexible scoring and management easiness. This questionnaire yields data on distinct aspects of suicidality, being more parsimonious than separate administration of a bunch of questionnaires. 2017 artículo científico 0120-8322 https://www.redalyc.org/articulo.oa?id=28354699005 https://www.redalyc.org/journal/283/28354699005/ https://www.redalyc.org/journal/283/28354699005/html/ https://www.redalyc.org/journal/283/28354699005/28354699005.epub https://www.redalyc.org/journal/283/28354699005/movil 10.25100/cm.v43i4.2294 en http://www.redalyc.org/revista.oa?id=283 Colombia Médica application/pdf Universidad del Valle Colombia Médica (Colombia) Num.4 Vol.48 |
