The relationship between attention deficit hyperactivity disorder and child temperament

Abstract

This study examined empirical and theoretical differences and similarities between attention deficit hyperactivity disorder (ADHD) and child temperament in 32 ADHD children aged 6–11 years, and a comparison group of 23 children with similar sociodemographic characteristics. Children were assessed for ADHD symptoms (hyperactivity, impulsivity, and inattention) and dimensions of child temperament (negative reactivity, task persistence, activity, attentional focusing, impulsivity, and inhibitory control) using standardized parent reports and interviews. Symptoms of ADHD and temperament dimensions were correlated; children in the ADHD group had significantly higher scores on negative reactivity, activity and impulsivity, and lower scores on task persistence, attentional focusing and inhibitory control than normative samples. Results indicate that although the constructs of ADHD and temperament have been regarded as two separate bodies of knowledge, theoretical and empirical overlaps exist. Applied implications are discussed.
