NPM: 9: Bullying
Intervention Components (click on component to see a list of all articles that use that intervention): CLASSROOM, Peer-led Curricular Activities/Training, SCHOOL, Assembly, Media Campaign (Print Materials, Public Address System, Social Media), Distribution of Promotional Items, POPULATION-BASED SYSTEMS, COMMUNITY, Training, Event, Media Campaign (Print Materials, Radio, TV), Distribution of Promotional Items

Intervention Results:

• Students in the intervention group reported a significantly higher rate of decline in verbal victimization compared to control students. The difference was only significant among males.
• For physical victimization, the decline in the intervention group compared to the control group was in the expected direction but did not reach statistical significance (p=0.069). This near significant difference was accounted for by males.

Intervention Results:

• Overall, there was no difference in relational (RR=0.96, 95% CI: 0.86-1.08) or physical (RR = 1.01, 95% CI: 0.87-1.17) victimization comparing the intervention schools to the control schools over the two-year period.
• When stratified by race/ethnicity, white students in intervention schools were 27.5% less likely to report relational (RR=0.72, 95% CI: 0.53-0.98) and 36.6% less likely to report physical victimization (RR=0.63, 95% CI: 0.42-0.97) compared to white students in control schools. No statistically significant results were found for students of other race/ethnicity groups.
• No significant effects were found when results were stratified by gender or grade.

Intervention Results:

Victimization - Traditional Bullying

• The study only reported significant findings and findings with percentile changes of 15% or more.
• With regard to composite victimization, comparing 7th grade females postintervention to those pre-intervention, there was a 31.1% decrease in reports of being bullied (p=0.022). Comparing 8th grade females post-intervention to those pre-intervention, there was a 25.0% increase in reports of the frequency of being bullied (p=0.038).
• With regard to physical victimization, comparing 8th grade females postintervention to those pre-intervention, there was a 20.0% increase in reports of being physically bullied (p=0.035).
• With regard to verbal victimization, comparing 8th grade females post-intervention to those pre-intervention, there was a 35.0% decrease in reports of being indirectly verbally bullied (p=0.035).
• With regard to relational victimization, comparing 7th grade females postintervention to those pre-intervention, there was a 34.4% decrease in reports of being excluded (p=0.009).

Perpetration/Aggression - Traditional Bullying

• The study only reported significant findings and findings with percentile changes of 15% or more.
• With regard to composite victimization, comparing 8th grade females postintervention to those pre-intervention, there was a 35.6% increase in reports of taking part in bullying others (p=0.003). For 7th grade males, there was a 21.8% increase in reports of taking part in bullying others; however, the difference did not reach statistical significance.

Intervention Results:

Victimization - Traditional Bullying

• Schools that agreed to district-wide implementation became part of HALT!, while districts that chose to implement at the building level became part of PA CARES. Results were reported separately for the different sites.
• Results from 999 high school students in 3 schools in Cohort 1 after 2 years of program implementation of HALT! showed a statistically significant decrease in reports of being bullied.
• Results from 6048 high school students in 7 schools after 1 year of program implementation of PA CARES showed a significant decrease in reports of being bullied.

Pepetration/Aggression - Traditional Bullying

• Schools that agreed to district-wide implementation became part of HALT!, while districts that chose to implement at the building level became part of PA CARES. Results were reported separately for the different sites.
• Results from 999 high school students in 3 schools in Cohort 1 after 2 years of program implementation of HALT! showed a statistically significant decrease in reports of bullying others. Results from 7446 high school students in 13 schools in Cohort 2 after 1 year of program implementation of HALT! showed statistically significant fewer reports of bullying others and fewer reports of students who could join in bullying. Results from 12972 middle school students in 15 schools in Cohort 2 after 1 year of program implementation of HALT! showed statistically significant fewer reports of students who could join in bullying.
• Results from 9899 middle school students in 13 schools after 1 year of program implementation of PA CARES showed a slight but non-significant decrease in the reports of students bullying others. Results from 6048 high school students in 7 schools showed a significant decrease in reports of bullying others.
