Number of participants: Participants included 120 psychiatric inpatient adolescents, 138 high school students, 120 psychiatric inpatient adults, and 135 undergraduate university students.

Summary:
The present study examined the reliability and validity of a brief self-report measure of past suicidal behavior, the Suicidal Behaviors Questionnaire-Revised (SBQ-R). The coefficient alpha estimate ranged from 0.76 (undergraduate sample) to 0.88 (psychiatric adolescent inpatient sample), depending on the sample. Logistic regression analyses provided empirical support for the usefulness of the SBQ-R as a risk measure of suicide to differentiate between suicide-risk and nonsuicidal study participants. Receiver operating characteristic (ROC) analyses indicated that the most useful cutoff scores on the SBQ-R were 7 for nonsuicidal samples, and 8 for clinical samples. Both the single SBQ-R Item 1 and SBQ-R total scores are recommended for use in clinical and nonclinical settings.
