Relevance. Executive functions are mental processes that allow the organization of behavior. These functions are associated with intelligence, creativity and citizenship skills, while their defi cit is associated with behavioral problems. Studies point out the relationship between sleeping habits and exposure to screens with behavioral disorders, which is why the present study shows the predictive role that these habits have on the development of executive and behavioral processes. Objective is to evaluate the variance of executive functions based on sleep habits and exposure to screens. Method and Sample. A study was developed under the positivist paradigm, it is quantitative, with non-experimental design, cross-sectional and predictive scope. The sample is formed of adolescents enrolled in two schools in Cúcuta-Colombia. Through two-stage sampling,  schools were selected and subsequently, through stratifi ed random sampling, a sample of  adolescents was chosen. To collect information, the following questionnaires were administered: ) Sociodemographic data questionnaire; ) questionnaire of daily habits and practices; ) Behavioral Assessment of Executive Function Questionnaire (BRIEF-). Results. Low quality of sleep and an increased use of phone and tablet before sleeping were identifi ed. While the use of screens occurred between one and three hours a day, a preference for television and videos on the Internet was registered. In the proposed predictive models, it was found that the use of screens and hours of sleep predict about % of the variance of inhibitory control. Likewise, it was found that the predictive effect of habits on inhibitory control is greater in men, explaining about % of the variance.
