Take a Stand Against Bullying: Evaluation of the Efficacy of a School-wide Program for Middle School Students

Factorial ANOVA and MANOVA procedures generated statistically significant posttest group and gender differences following intervention. The group receiving no intervention reported greater mean scores in overall bullying behaviors and fears related to such behaviors than groups receiving varying degrees of intervention. Additionally, boys self-reported more bullying behaviors, including both physical and verbal bully perpetration and victimization, than girls. Then, using a MANOVA with repeated-measures, significant time (pretest, posttest) by group (intervention, comparison) differences were found. These results tentatively support the Take a Stand Against Bullying program as a useful bullying intervention program. There were research limitations involving internal and external validity concerns, suggesting caution in drawing any firm conclusions.
