Behavior rating scales: Concordance between multiple informants in the diagnosis of Attention-Deficit/Hyperactivity disorder

Attention-Deficit/Hyperactivity Disorder (ADHD) emerges in early childhood and is characterized by inattention, impulsivity, and hyperactivity. Behavior rating scales serve as an essential component in a comprehensive assessment of ADHD. Unfortunately, there is often disconcordance between informants' responses, resulting in lower interrater reliability. The current paper reviews variables that may decrease the diagnostic utility of behavior rating scales in the diagnosis of ADHD. Suggestions are offered for future research to improve interrater reliability with rating scales.
