Assessment of Psychiatrically Hospitalized Suicidal Adolescents: Self-Report Instruments as Predictors of Suicidal Thoughts and Behavior

Abstract

The validity and clinical utility of the Reynolds Adolescent Depression Scale, Beck Hopelessness Scale, Suicidal Ideation Questionnaire-Junior, and Suicide Probability Scale (SPS) were examined longitudinally among suicidal adolescents. Between 1998 and 2000, 289 psychiatrically hospitalized, suicidal youth, ages 12 to 17 years, participated in this study. Self-report measures were completed at baseline. Clinician-rated suicidality and suicide attempt were collected at baseline and 6-month follow-up. Baseline self-reports were internally consistent and strongly intercorrelated within male, female, white, and black subsamples. All of the measures predicted follow-up suicidality and suicide attempts. Using published cutoff scores, the Beck Hopelessness Scale and SPS were moderately to highly sensitive predictors of subsequent suicide attempts, as was the Suicidal Ideation Questionnaire-Junior for predicting suicide attempts and broad suicidality. Alternative cutoff scores that predicted outcomes with moderate and high sensitivity also were examined, with attention to resultant sacrifices in specificity. Baseline self-report scores predicted follow-up suicidality. SPS contributed uniquely to prediction of future suicidality and suicide attempt. SPS may supplement other sources of information when assessing suicide risk with this population.
