This Curricular Unit globally aims to promote a view about intervention in the field of Psychology, Justice and Deviance, which is simultaneously critical, flexible and adjusted to the needs of individuals and the specificities of the contexts. Particularly, we intend to promote skills concerning the design, evaluation and implementation of individual and group intervention programs on antisocial behaviour and delinquency at various contexts (family, school, community; youth justice system, prisons), and at various levels (prevention, treatment). Teaching is supported by updated knowledge about risk and protective factors, as well as evidence-based intervention models. The review and training of models and strategies includes intervention directed to individuals at distinct developmental stages, as well as distinct levels of involvement with the problems at issue.
