Inhibitory control and symptomatology of attention deficit hyperactivity disorder

Abstract

BACKGROUND: Inhibitory control has been described as a factor causing difficulties in the regulation present in the ADHD. Objective: The aim was to analyze the relationship between inhibitory control and symptoms of ADHD in a sample of 81 subjects diagnosed with ADHD (Mage=10.05, SD=2.53). METHODS: A quantitative, cross-sectional and correlational scope research was carried out. The instruments used were the ADHD RS IV and SIMON experiment. Correlation inferential statistical regression and regression processes were applied. RESULTS: Three regression models were tested, where inhibitory control presents a significant prediction with the (a) attention deficit F (1,79) =20.69, p=<.001, R 2 =.21, (b) hyperactivity and impulsivity F (1, 79) =5.90, p=.01, R 2 =.07 and (c) the combination of both (a+b) F (1, 79) =13.25, p=< .01, R 2 =.14. CONCLUSIONS: The findings suggest that inhibitory control is one of the main executive functions that determines the degree of affectation of the symptomatology of the child population with ADHD.
