International Self-Report Delinquency Study (ISRD)

International
Self-Report
Delinquency Study

An ongoing international, collaborative study that aims to describe and explain adolescents’ experiences with crime and victimization, to test criminological theories, and to develop recommendations for prevention and interventions. ISRD1 was pioneered in 1992; this standardized school-based survey has just been completed for the fourth time (ISRD4) (2020-2024) with over 35 countries participating. ISRD4 supplements the classroom-based survey of 13 to 17 year olds with an internet-based sample of 16-17 year-olds. Planning for ISRD5 is currently underway, with an anticipated start in 2026-2027.

Two Primary Objectives of the ISRD Study:

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.

Participating Countries

Initially, the primary focus has been on Europe, but now the study includes countries all across the globe.

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) took place in 36 countries, and data has been collected in about 35 countries for ISRD4.

Methodology and Sample

The project uses a common research protocol, which standardizes questionnaire content and administration, and prescribes comparable sampling procedures in participating countries.  Over the different data collection periods, some adjustments were made in the research protocol.  For ISRD4, we focus on 13 to 17 year old students, with a target sample size for each national team of a representative sample of 1,800 school students, collected in two cities.  The self-report questionnaire has been  administered online within the classroom setting, supervised by an external data collector. Some national teams also gathered a supplemental national sample of 16 and 17  year-olds recruited via the internet, using an abbreviated form of the standard ISRD4 questionnaire.
