The US Department of Education, National Center for Education Statistics (NCES), requested testing of questions about school bullying that are part of the School Crime Supplement (SCS) to the National Crime Victimization Survey sponsored by the Bureau of Justice Statistics. The main purpose of this cognitive research was to test proposed changes in question wording to be consistent with the Centers for Disease Control's (CDC) definition of "bullying," including "cyber-bulling." The long-standing SCS question about bullying did not include the concepts of repetition or power differential, and NCES was interested in testing whether and how these concepts might be added to the bullying items. In the questionnaire being tested, one version maintains the original question on bullying and adds two new follow-up questions to capture these two components (this would help preserve the time trend). In the other version, a single new question on bullying that includes the two new components was tested. In addition, some fairly minor changes to other questions in the SCS not related to bullying were made based on previous research, and this testing assessed those changes.
