Developing the symptoms and functional impairment rating scale: A multi-dimensional adhd scale

Abstract

Objective This research developed a practical, multi-dimensional attention deficit hyperactivity disorder (ADHD) rating scale (i.e., the Symptoms and Functional Impairment Rating Scale, SFIRS) for Chinese children, aged 6–12 years, with ADHD. Methods The structural validity, criterion validity, internal consistency, and test-retest reliability of the scale were evaluated. Item screening was conducted with 412 ADHD patients and 322 developmentally typical controls. Results The scale includes 44 items, divided among Hyperactivity-Impulsivity, Self-Control, Inattention, Self-Management, Academic Performance, and Social Interaction. The six-factor model showed good data fit, with each factor significantly correlated with its corresponding criterion (r=0.690–0.841). The Cronbach’s α of the full scale was 0.976. Total score test-retest reliability was r=0.816 (p<0.01). Conclusion The SFIRS thus demonstrated good reliability and validity and may be used to assess ADHD among children aged 6–12 years in China.
