A novel school-based approach to screening for attention deficit hyperactivity disorder

Area of Science:

• Child and Adolescent Psychiatry
• Developmental Psychology
• Educational Psychology

Background:

• Current screening methods for attention deficit hyperactivity disorder (ADHD) often yield high false positive rates.
• Accurate ADHD detection in school settings is crucial for timely intervention and support.

Purpose of the Study:

• To evaluate the efficacy of a novel two-stage screening process for ADHD in a school-based population.
• To determine if incorporating a standardized teacher-to-teacher interview enhances the diagnostic accuracy of traditional ADHD screening questionnaires.

Main Methods:

• A school-based study involving 1026 pupils (ages 6-12) in Hunan Province, China.
• Stage 1: Parent and teacher questionnaires for initial ADHD screening.
• Stage 2: Standardized teacher-to-teacher SNAP-IV interview for screen-positive cases.

Main Results:

• Stage 1 screening identified 230 (22.4%) students as screen-positive, with a false positive rate of 20%.
• Stage 2 screening of 65 screen-positive students resulted in a significantly reduced false positive rate of 3% for ADHD diagnosis.
• The two-stage process achieved a sensitivity of 0.83 and a specificity of 0.97 for ADHD diagnosis.

Conclusions:

• A two-stage screening process, including teacher-to-teacher interviews, can substantially decrease false positives in school-based ADHD detection.
• This enhanced screening method improves clinical utility for identifying ADHD in children.
• The approach maintains high sensitivity, ensuring effective identification of true ADHD cases.
