Abstract

Highlights: The Japanese ADHD-RS had confirmed factor structures and showed good reliability. Japanese preschoolers scored significantly lower in the ADHD-RS than US children. P-ADHD-RS had high sensitivity and specificity, and moderate PPV in 90th percentile. Abstract: Background: Children with ADHD show multiple difficulties in their lives. Its early detection is important to provide timely intervention. Aims: To evaluate the psychometric properties of the Japanese version of the home and school form of the ADHD-Rating Scale-IV (P- and T-ADHD-RS) for screening five-year-olds with ADHD. Methods: The parents and teachers of 838 children (452 boys, 386 girls; including 28 boys, 18 girls diagnosed ADHD) completed the ADHD-RS and the Strengths and Difficulties Questionnaire in a community health check-up. Results: The P- and T-ADHD-RS confirmed the two-factor model (Inattention and Hyperactivity-Impulsivity) and internal consistencies (CFI = 0.968, 980; RMSEA = 0.049, 0.055; SRMR = 0.030, 0.024; α = 0.86–.93). Japanese boys and girls scored significantly lower in all scales of the P- and T-ADHD-RS ( d = 0.65–1.14, 0.36–0.59) than US children. The P-ADHD-RS showed higher accuracy in area under the curve (AUC), sensitivity, and positive predictive value (PPV) than the T-ADHD-RS (AUC = 0.955, 0.692; sensitivity = 89.13%, 30.23%; PPV = 46.59%, 16.05%). Implications: The P-ADHD-RS shows good reliability and validity for screening children with possible ADHD in a community. Longitudinal studies are needed to examine its predictive validity of adaptation in their lives at school.
