In an online survey (N = 338) at a large midwestern university, frequency counts indicated that 51 (15.1%) undergraduate students were cyberbully victims during college, and 27 (8.0%) were cyberbully offenders during college. In simultaneous regressions, maternal attachment anxiety explained unique variance in cybervictimization and cyberoffending. In multivariate analyses of variance, cyberbully victims (vs. nonvictims) reported higher depression, loneliness, and maternal attachment anxiety, and cyberbully offenders (vs. nonoffenders) reported lower self-esteem and higher maternal attachment anxiety. College counseling implications are discussed.
