Past suicidal behaviors including ideation and attempts have been identified as significant risk factors for subsequent suicidal behavior. However, inadequate attention has been given to the development or validation of measures of past suicidal behavior. 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). Participants included psychiatric inpatient adolescents, high school students, psychiatric inpatient adults, and undergraduates. 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.

This investigation was conducted to validate the Beck Depression Inventory--II (BDI-II; A. T. Beck, R. A. Steer, & G. K. Brown, 1996) in samples of adolescent psychiatric inpatients. The sample in each substudy was primarily Caucasian. In Study 1, expert raters (N=7) and adolescent psychiatric inpatients (N=13) evaluated the BDI-II items to assess content validity. In Study 2, confirmatory factor analyses of several first-order solutions failed to provide adequate fit estimates to data for 205 boys, 203 girls, and the combined sample. Exploratory factor analyses identified new item-factor solutions. Reliability estimates were good (range =.72 to.91) for the BDI-II total and scale scores. In Study 3 (N=161 boys and 158 girls from Study 2), preliminary evidence for estimates of concurrent, convergent, and discriminant validity were established for the BDI-II.
