Dimensões comportamentais do Transtorno de Déficit de Atenção/Hiperatividade: influência parental e impacto no desempenho escolar

Abstract

Attention Deficit/Hyperactivity Disorder (ADHD) is among the most common and valid psychiatric disorders. However, ADHD symptoms course remains unclear due to its very heterogeneous clinical presentation. Differences between ADHD behavioral dimensions (i.e., inattention and hyperactivity-impulsivity) may account for ADHD phenotypic heterogeneity and to understand how they are related at the behavioral level is of utmost importance. This study investigated 1) how mothers’ ADHD symptoms influence children’s inattentive and hyperactive-impulsive symptoms, and 2) how ADHD dimensions are related to intelligence and academic performance. First, we found that maternal hyperactive-impulsive symptoms were the main influence on the shared variance between children’s inattention and hyperactivity-impulsivity. Notwithstanding, some of the maternal symptoms’ influence on children’s hyperactivity-impulsivity was accounted for by children’s inattentive symptoms. Second, the results showed that ADHD inattention mediates the influence of general intelligence on academic performance. Even though hyperactivity-impulsivity was not related to intelligence, it was a moderator of inattentive symptoms’ impact on academic performance.
