Hyperactivity in the Behavioral Approach System (BAS) and hypoactivity in the Behavioral Inhibition System (BIS) are related to substance use and antisocial personality disorders, andan inherent variable is impulsivity. Objective: To determine the association between BIS / BAS systems, impulsivity and types of crime, with drug consumption. Method: quantitative crosssectional and correlational research. Sample: 175 Persons Deprived of Liberty. Instruments: BIS / BAS Plutchik Impulsivity Scale and a specific questionnaire was developed to evaluate sociodemographic variables. A significant correlation was found between drug use, crime (p .002) and impulsivity (p <.001), as well as other prison variables linked to consumption. No association was found between BIS / BAS systems and drug consumption.

Life skills are considered necessary to achieve healthy human development and their teaching has spread globally through the implementation of prevention programs in school environments. However, these programs require easy to use instruments with adequate psychometric properties. This study aims to provide validity evidence based on the internal structure for the Life Skills Test, and to design a short version to assess life skills in Mexican adolescents and young people in school. In this psychometric study the Life Skills Test was administered to 897 students (Mage = 20.70, SD = 3.73); 74.7 % were women (M age = 20.49, SD = 3.16), 25.3 % men (M age = 21.33; SD = 5.01). 2.6 % were secondary and upper secondary education, 95.4 % undergraduate and 2% postgraduate students. The original test consists of 80 items and identifies ten life skills. In this research, the original test did not s...
