The EDT is a research database comprising of comprehensive judicial information on European terrorist and violent extremist offenders, convicted from 2012 onwards.
The database is the result of a European cross-border collaboration between judicial organizations and scientists within the European Union. The main aim of the EDT is to create a unique and large dataset to examine specific risk and protective factors for terrorism. The EDT includes a control group of convicted violent offenders unrelated to terrorism or extremism (Alberda et al, 2021).
The coded EDT data consists of personal and contextual offender information from judicial files of the participating EU Member States. These files include comprehensive documentation from the police, public prosecution, detention, forensic mental health assessment reports and probation reports.
These qualitative files together allow for a comprehensive overview of personal and contextual characteristics of violent extremist and terrorist offenders and their acts.
Based on these judicial sources, a large number of potential risk factors, protective factors, and indicators for terrorism are coded in the EDT. These encompass demographic data, childhood circumstances, trigger factors, ideologies, motives, mental health issues, and the nature of the terrorist offence and type of sentence. Information from forensic mental health assessments is included to provide insight into mental health issues as possible risk factor for terrorist acts.
The EDT dataset can be used to conduct studies aimed at the identification of significant personal and contextual risk and protective factors for terrorism and violent extremism, improving and validating risk assessments, as well as identifying pathways into terrorism and radicalization. Moreover, this data can assist in the design of effective policy, prevention and intervention practices regarding potential violent extremist and terrorist offenders in Europe and elsewhere.
