An international collaborative study on delinquency, victimization, substance use among 7th, 8th and 9th graders.

The ISRD study is an ongoing international research study of delinquency and victimization among youth, using standardized instruments and data collection procedures. The primary focus has been on Europe, but the study now includes a number of non-European countries (e.g., China, Cape Verde, the US and Venezuela).

The ISRD study has two primary objectives:

  • To observe and compare differences, similarities, and trends in offending and victimization between countries
  • To explore and test theoretical issues related to juvenile delinquency and victimization, while maintaining relevance for policy purposes.

Data for the ISRD study were first collected in 1992-1993 among 13 countries (ISRD1), and then between 2005 and 2007 in 31 countries (ISRD2). The third data collection sweep (ISRD3) is currently on-going, with 35 partners across the globe.

ISRD3 is still open for participants. Researchers interested in joining the ISRD3 data collection sweep may contact Professor Ineke Haen Marshall (, or any of the members of the ISRD3 Steering Committee.

The ISRD website is based on the webserver of Northeastern University. The homepage will be used both for dissemination of information to the public, and for internal coordination of the ISRD network.
