This three-article dissertation presents three standalone articles that address bullying trends over time within the United States (US), gaps in bullying prevention program outcomes (both within the US and internationally), and the role of study and methodological features on the findings. The first article used meta-regression to establish trends in different types of bullying involvement from 1998 to 2017, identified factors that help explain variation in bullying trends, and determined differences in those trends by gender and grade. The second article used meta-analysis to examine the effectiveness of bullying prevention programs on three subtypes of traditional bullying victimization: physical, relational, and verbal, both within and outside the US. The third article also used meta-analysis to examine the effectiveness of bullying prevention programs, however, this article focused on outcomes by gender, again both within and outside the US. Both articles two and three also analyzed how different study level methodological features impact these outcomes. Taken together, these three articles provide insight into the state of bullying within the US over the past two decades and identify gaps in outcomes of bullying prevention programs both within the US and internationally.
