Bullying affects large numbers of U.S. students in elementary schools and is associated with short and
long-term harms for both victims and bullies. Although prevention is critical, schools also need
effective interventions for dealing with bullying once it occurs. Funded by the National Institute of
Justice, and in collaboration with the Oakland Unified School District and No Bully, WestEd conducted
a two-year study of the impacts of the No Bully System (NBS) - a set of interventions
designed to activate adult and peer support systems within the school for the targets of bullying. No
Bully trains staff to prevent and interrupt student harassment and bullying and ensure school-wide antibullying policies are in place. The core component of NBS is the Solution Team where a trained adult
facilitator (Solution Coach) brings together a group of 6-8 students (Solution Team) that includes the
bully or bullies, bystanders and pro-social peers, and leads the team through a series of three brief
meetings to end the bullying of one of their peers by cultivating empathy and developing peer-driven
solutions. The target is not included in the initial meetings though s/he is invited to attend the final
session.
The collection contains 2 SPSS data files: NoBully_ST-Log-Data_final_archive.sav (n=94; 47 variables) and No-Bully_Survey-Data_final.sav (n=6410; 204 variables).
description: The purpose of this study was to conduct an evaluation that will add to the literature on promising antibullying programs that improve school safety and climate, reduce bullying, and improve outcomes for
the targets of bullying. This randomized controlled trial provides the first rigorous test of the No Bully
System (NBS) to determine if its promise holds up in a rigorous evaluation. The study was designed to address
the following research questions:

Does NBS reduce the recurrence of bullying perpetration and
victimization among students involved in incidents targeted by Solution Teams?; Does NBS reduce
bullying perpetration and victimization among students at risk of bullying involvement (victims and
perpetrators)?; Does NBS improve perceptions of school safety, peer support, and other indicators
of school climate among all students in schools?;
description: To examine the first research question, data come from Solution Team Logs that Solution Coaches completed as required by the No Bully System (NBS) program. In addition to capturing program fidelity information (i.e., how closely Solution Coaches followed the suggested process), the logs contain questions that the Solution Coaches ask the victim of bullying about the frequency, intensity and perceptions of school safety at four timepoints:
Initial assessment prior to a Solution team (pre-intervention),; After the first Solution Team meeting (during intervention),; Near the end of the Solution Team (2-3 weeks later, or at the end of the Solution Team intervention), and; Two to three months after a Solution Team has been completed (post-intervention).; Victims of bullying who agreed to participate in Solution Teams (n=83) comprise the analytic sample.
Research questions two and three rely on self-report survey data collected from participating grade 4-5 students at two time points: in the Fall or Spring of the 2015/16 academic year and in the Spring of the 2016/17 academic year, the second year of implementation. Research question 3 relies on self-report survey data collected from all grade 3-5 students in the Spring of the 2016/17 academic year.
description: This data collection includes variables on bullying perpetration (e.g., "I call other students bad names") and victimization (e.g., "I am hit or kicked by other students"), as well as demographic variables.
The collection contains 2 SPSS data files: NoBully_ST-Log-Data_final_archive.sav (n=94; 47 variables) and No-Bully_Survey-Data_final.sav (n=6410; 204 variables).

description: To examine the impact of No Bully System (NBS), this study used a cluster randomized experimental design involving 24 elementary schools served by Oakland Unified School District. In the summer of 2015, schools were randomly assigned to either an experimental group or a wait-listed control group--with 12 schools per group. Prior to randomization, the sample was stratified by types of school-wide programming being implemented (no program, Positive Behavior Intervention and Supports, Social-Emotional Learning or Restorative Practice, or a combination of 2 or more of these programs). Schools were then randomized within each stratum.
Treatment schools began implementing NBS in Fall 2015 and continued to do so until the end of the second academic year in Spring 2017. During the same time-period, control schools conducted business as usual (e.g., continued to address bullying as they usually do/had done in the past).
