ABSTRACT
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
