The trajectory of the group in this field is focused on child and adolescent development, as well as the study of different risk and protective factors associated with the appearance of problematic and antisocial behaviours and substance use. In this regard, different studies and research projects which were carried out allowed, in turn, to delve into the prevention of risk behaviours through the elaboration and adaptation of prevention and intervention programmes. The group has a wide experience in the field, which is reflected in the publication of numerous articles in scientific journals, book chapters, books and manuals of prevention programmes.
