Validity of the Suicide Behaviors Questionnaire-Revised in patients with short-term suicide risk

Background and objectives: Suicide is known as a public health problem; however, there are few validated scales with no predictive validity. The aim of this study was to assess the validity of the Spanish version of The Suicidal Behavior Questionnaire-Revised in patients with suicidality. Methods: We applied the Spanish version of The Suicidal Behavior Questionnaire-Revised and 2 other scales to patients with suicide risk. Thirty days later we reassessed to determine the predictive validity for suicide attempt or suicide. Results: 484 patients with suicidality were screened of which 417 were eligible and 411 were evaluable. Factor analysis found a domain with an eigenvalue of 2.0 explaining 50.1% of the variance. With a cutoff point ≥11 the NPV was 98.3% (IC95%, 95.2-99.6) and the PPV was 8.7% (IC95%, 4.7-14.4). Conclusion: The Spanish version of The Suicidal Behavior Questionnaire-Revised, similar to the English version, has moderate internal consistency, adequate concurrent validity and predictive validity

Validación del cuestionario SCOFF para el cribado de los trastornos del comportamiento alimentario en adolescentes escolarizadas / Validation of the scoff questionnaire for screening the eating behaviour disorders of adolescents in school

Objetivo. Determinar la consistencia interna y la validez de criterio del cuestionario SCOFF en adolescentes para el cribado de los trastornos de la conducta alimentaria (TCA). Diseño. Estudio de validación con muestreo probabilístico. Emplazamiento. Tres colegios en Bucaramanga, Colombia. Participantes. Un total de 241 estudiantes seleccionadas al azar entre 1.595 elegibles. Intervenciones principales. Cuestionario SCOFF y entrevista semiestructurada CIDI, aplicados de manera independiente. Mediciones principales. Características demográficas, prueba alfa de Cronbach, análisis de sensibilidad, especificidad, valores predictivos, prueba kappa media de Cohen y curva ROC. Resultados. La sensibilidad encontrada fue del 81,9% (intervalo de confianza [IC] del 95%, 70,7-89,7) y la especificidad, del 78,7% (IC del 95%, 71,7-84,6). El área bajo la curva ROC fue de 0,8596 (IC del 95%, 0,8108-0,9084); la prueba alfa de Cronbach fue de 0,436 y la kappa media de Cohen, de 0,554 (IC del 95%, 0,425-0,683). Conclusiones. El cuestionario SCOFF es una alternativa aceptable para el cribado de grupos de población adolescente por su sencillez y rapidez de administración

Objective. To determine the internal consistency and criteria validity of the SCOFF questionnaire for screening adolescent eating behaviour disorders. Design. Validation study with stochastic sampling. Setting. Three schools at Bucaramanga, Colombia. Participants. 241 students selected at random from 1595 possible ones. Main interventions. SCOFF questionnaire and semi-structured CIDI interview, administered independently. Main measurements. Social and personal details, Cronbach’s alpha, sensitivity analysis, specificity, forecast values, Cohen mean kappa test, and ROC curve. Results. Sensitivity found was 81.9% (95% CI, 70.7-89.7) and specificity, 78.7% (95% CI, 71.7-84.6). The area under the ROC curve was 0.8596 (95% CI, 0.8108- 0.9084); the Cronbach’s alpha test, 0.436, and the Cohen mean kappa, 0.554 (95% CI, 0.425-0.683). Conclusions. The SCOFF questionnaire is an acceptable alternative for screening groups of adolescents because of its simplicity and speed of administration
