This dataset includes the data used in the posters presented at the 4th World Conference on Personality, XII Jornadas de la Asociación Iberoamericana para la Investigación de las Diferencias Individuales, and XIII Jornadas de la Asociación Iberoamericana para la Investigación de las Diferencias Individuales. More especifically it includes data about 150 Spanish young offenders (82.0% male) from Tarragona (Spain), with ages between 15 and 19 years old. This sample of young offenders was recruited from open intervention programs in the province of Tarragona (Catalonia, Spain). These programs are measures of criminal responsibility that are carried out in the social and family environment of the young person, so they do not involve deprivation of liberty. The data includes their ages, gender, responses to the Indirect-Direct Aggression Questionnaire (I-DAQ), and responses to the Inventory of Callous-unemotional traits and Antisocial behaviour (INCA questionnaire).
