Members of our institute, Dr. Závora and Mgr. Skořepa, are co-authors of a recently published study in an impacted scientific periodical. The study deals with a case of delinquent behavior of an adolescent in whom the usual causes of such behavior are not present. This is a long-term project of our institute to publish two thematically similar case studies (a boy and a girl). This is a unique qualitative research study that explores the experiences of children from otherwise functional families and environments who nevertheless engage in extensive delinquent behaviors. The most difficult part of the research is to find these extremely specific cases and understand this specific experience.
