Research suggests that individual differences in attachment style predict the perpetration of digital dating abuse. In addition
to attachment style, no research, to our knowledge, has explored the role of mate value in the perpetration of digital dating
abuse. In this paper, we argue that digital dating abuse is a contemporary cost-inflicting mate retention behaviour, where
larger mate value discrepancies between partners are associated with higher levels of digital dating abuse (n = 167). As
expected, high mate value discrepancy and attachment anxiety were associated with high levels of digital dating abuse. We
provide novel support for the relationship between mate value discrepancy and digital dating abuse. Our findings provide
support for additional, unexplored factors which lead to the perpetration of digital dating abus
