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, R2=.21, (b) hyperactivity and impulsivity F(1,79)=5.90, p=.01, R2=.07 and (c) the combination of both (a+b) F(1,79)=13.25, p=< .01, R2=.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.

Validación de la Escala de Impulsividad Bis 11-C para su Aplicación en Adolescentes Ecuatorianos
Barratt scale (BIS) is an assessment tool often used to evaluate impulsivity. In this study, an analysis of the psychometric properties of the BIS 11 c scale Ecuadorian adolescent students (N = 245) is performed. Internal consistency through Cronbach’s alpha coefficient and homogeneity of the items were evaluated. For assessing the construct validity we perform a confirmatory factor analysis. The results obtained were acceptable parameters of valid and reliability to use the BIS 11 c scale in Ecuadorian adolescents. Finally, a discriminant analysis in a clinical sample of 18 students with ADHD was conducted.
