TRAMA – "Database on the History of Legal Psychology in Brazil and Criminal Justice and Public Security Policies Related to Youth" is a digital database of concepts and analytical categories present in the theoretical corpus of Brazilian legal psychology and violence studies. With a focus on the historical research of national production on legal psychology, violence studies, and public security policies related to youth, the research creates an electronic archive of public utility and free access for online searches. The database allows users to explore concepts and analytical categories developed in the field of crime and violence studies, with a particular emphasis on legal psychology and public security policies for youth. Each entry includes the term's definition, a transcription of its explanation, and references to the author(s) and works where it can be found. This resource serves as an information source for research, supporting researchers from undergraduate to postgraduate levels. The project holds the potential to integrate psychology with other areas of knowledge, enabling faculty and students involved to experience not only research learning but also the necessity of interdisciplinarity to address complex topics, such as those related to violence studies. The database is the result of a research project coordinated by Professor Juliana Ferreira da Silva and is linked to the Graduate Program in Psychology at the Catholic University of Brasília.
