WHAT THE TEST MEASURES

About This Assessment

Questionnaire for Early Detection of Addiction in Adolescents Test

Adolescent Early Substance Use Disorder Screening Questionnaire Test - Symptoms and Signs

addiction drug addiction

This questionnaire is intended to help identify early indicators of problematic substance use in adolescents. The Adolescent Early Substance Use Disorder Screening Questionnaire is designed for use by caregivers or other informants to support initial triage and determine whether further clinical assessment may be warranted.

Developed by Thomas M. Achenbach and Mary M. Achenbach, it includes 38 items and typically takes about 7 minutes to complete. Items focus on observable behavior and contextual risk signals (e.g., changes in functioning, emotional/behavioral concerns, and peer/environmental factors) relevant to substance use risk.

The Adolescent Early Substance Use Disorder Screening Questionnaire is a screening instrument and does not establish a diagnosis on its own. Results are best interpreted in conjunction with clinical interview, collateral information, and, when indicated, referral for comprehensive substance use evaluation.
