The aim of this study is to evaluate factors related to cessation of dangerousness of individuals under safety measures, through the study of psychiatric reports. This is a cross-sectional study, conducted through a retrospective analysis of expert psychiatric dangerousness cessation reports issued by the Federal District Coroner's Office, Brasília, Brazil. By examining official files, information was extracted from the reports (socio-demographic data, clinical characteristics, type of crime, historical characteristics and the search for items related to risk assessment present in instruments such as Historical, Clinical and Risk Management [HCR-20], Psychopathy Checklist -Revised [PCL-R], Two-Tiered Violence Risk Scale [TTV], Short-Term Assessment of Risk and Treatability [START] and others) and submitted to statistical analysis and then compared to other studies on the subject. The items most considered by the experts were those referring to PCL-R, START and the "non static" part of HCR-20 and TTV. For the non-cessation of dangerousness, we've found: absence of remorse, fragile behavioral control, early behavioral problems, juvenile delinquency. For the cessation of dangerousness, we've found: presence of social skills, balanced emotional state, presence of social support, adherence to rules, good coping
