In this study, we explored the use of the internet and information and communication technologies (ICT) and determined the prevalence of CDA among 105 emerging adults, with an average age of 23.2 years (SD = 3.65). Through an online cross-sectional study, our results indicate that emerging adults spend an average of 6.67 h a day online (SD = 3.34), with 37.6% communicating with their partner for more than 5 h daily via ICT. A high prevalence of CDA was observed: 62.9% victimization and 74.3% perpetration, with an emphasis on controlling behaviors. This study explores the relationship between problematic internet use (PIU) and CDA and highlights the normalization of CDA behaviours.</jats:p>engCyber dating abuseProblematic internet useEmerging adulthood.Faculdade de Artes e HumanidadesFaculdade de Ciências Sociaisconference object10.1007/978-3-032-05008-3_33
