Incremental Validity of Multi-Method and Multi-Informant Evaluations in the Clinical Diagnosis of Preschool ADHD

Abstract

Objectives: This study investigated the discriminative validity of various single or combined measurements of electroencephalogram (EEG) data, Conners’ Kiddie Continuous Performance Test (K-CPT), and Disruptive Behavior Disorder Rating Scale (DBDRS) to differentiate preschool children with ADHD from those with typical development (TD). Method: We recruited 70 preschoolers, of whom 38 were diagnosed with ADHD and 32 exhibited TD; all participants underwent the K-CPT and wireless EEG recording in different conditions (rest, slow-rate, and fast-rate task). Results: Slow-rate task-related central parietal delta (1–4 Hz) and central alpha (8–13 Hz) and beta (13–30 Hz) powers between groups with ADHD and TD were significantly distinct (p
