Several barriers exist to routine assessment of suicidal ideation (SI) in adolescents across settings, including insufficient time, tools, and training. Such barriers often result in the use of brief or even single-item assessments of SI, which may result in misclassification. The present study sought to compare single- and multi-item assessment of SI in adolescents, and to examine factors associated with different response profiles. Adolescents (n =206) were recruited from the community and completed a lab visit including a single and multi-item assessment for SI. Results suggest that two thirds of adolescents with passive SI go undetected when relying solely on a single-item screener, yet they present a similar clinical profile to those with passive SI who endorse the screener question. The present study provides support for the notion that multi-item assessment paints a more accurate, nuanced picture of SI among adolescents and may be an important component of routine screening.
