Numerous adolescents in the United States experience peer cybervictimization, which is associated with a series of internalizing (e.g., depression, anxiety, anger) and externalizing (e.g., aggression, substance use, risky sexual behavior) problems. The current study provides a systematic review and meta-analysis of existing research on these relationships. Included in the meta-analyses are 239 effect sizes from 55 reports, representing responses from 257,678 adolescents. The results of a series of random effects meta-analyses using robust variance estimation indicated positive and significant relationships between peer cybervictimization and a series of internalizing and externalizing problems, with point estimates of this relationship ranging from Pearson's r = .14 to .34. Implications for research and practice are discussed.

Adolescents’ Internet use is increasingly mobile, private, and unsupervised, which raises concerns given that the Internet increasingly serves as a medium for experiencing victimization. Although it is widely recognized that in-person victimization has a deleterious effect on adolescents’ educational outcomes, the extent to which cyber-victimization has similar effects is less well known. This systematic review and meta-analysis offers a synthesis of the relationship between cyber-victimization and educational outcomes of adolescents aged 12 to 17, including 25 effect sizes from 12 studies drawn from a variety of disciplines. A series of random-effects meta-analyses using robust variance estimation revealed associations between cyber-victimization and higher school attendance problems (r = .20) and academic achievement problems (r = .14). Results did not differ by provided definition, publication status, reporting time frame, gender, race/ethnicity, or average age. Implications for future research are discussed within context of theoretical, critical, and applied discussions.

The efficacy of youth violence prevention policies, programs, and practices partly depends on understanding the reasons for why students are targeted for victimization. However, what is known about why some students are targeted for victimization over others is limited to researcher-generated reasons and therefore may risk ecological validity. This study used a qualitative opencoding content analyses to make sense of 8531 students' open-ended responses about the reasons why they were targeted for victimization at school. Results identified 35 commonly reported reasons, many of which are underrepresented in previous literature. Students primarily reported reasons related to relational dynamics, physical characteristics, non-physical personal characteristics, and characteristics external to themselves. These results portray reasons for being targeted as a social phenomenon with both individual and contextual components. Implications for theory, research, and practitioners are discussed.
