The present study examined adolescents’ perpetration of Cyber-Based Dating Aggression (CBDA) in current, past, and potential future romantic relationships. The sample included 39 males and 47 females. Results revealed that, on average, CBDA occurred in 22.7% of relationships and that Monitoring was the subtype of CBDA that adolescents reported the most. Results also revealed that there was a significant gender difference in the perpetration of Relational CBDA from those adolescents reporting on past relationships. Moreover, there were significant positive correlations between CBDA and traditional adolescent dating aggression (i.e., face-to-face aggression), meaning that both of these types of aggression tended to co-occur in the same relationship. Lastly, length of relationship and relationship satisfaction did not significantly predict any subtype of CBDA in current and past relationships, however these variables significantly predicted Monitoring CBDA in future romantic relationships. Interpretations of these findings and suggestions for future research are provided.
