Getting the Best Return on Your Screening Investment: An Analysis of the Suicidal Ideation Questionnaire and Reynolds Adolescent Depression Scale

pp. 200—217

Abstract. Data from 64 adolescent inpatients admitted for serious suicidal ideation, 50 adolescent inpatients admitted following a suicide attempt, and 56 randomly selected high school control participants were used to evaluate the sensitivity, specificity, positive predictive value, and negative predictive value of the Suicidal Ideation Questionnaire (SIQ) and the Reynolds Adolescent Depression Scale—2nd Edition (RADS-2). The purpose of the study was to provide information necessary for selecting assessment tools to use in large-scale screenings of high school students for suicide risk. The hypothesis that a combination of mean scores on the two measures and critical item scores would provide the best clinical utility was partially supported. The SIQ was found to be very useful in discriminating between the study groups, whereas the RADS-2 did not perform as expected. The fewest false negatives would result from relying on RADS-2 scale scores > 63 and SIQ scale scores >14. However, the parsimonious and hence most cost-effective approach would be to rely on SIQ scale scores >14 in combination with SIQ critical Items 2, 3, and 4 for screening purposes.
