As cyberbullying research advances, many researchers have focused on identifying factors that might reduce the negative consequences associated with cyberbullying victimisation. One prominent factor receiving attention is the role of parental mediation in digital technology use, and how such mediation reduces the risk of cybervictimisation. Parents utilise different mediation strategies (i.e. restrictive, co‐viewing, instructive), which could potentially contribute to differential patterns in the relationships between cyberbullying victimisation and the associated psychosocial adjustment difficulties (i.e. depression, loneliness, anxiety). The present study investigated this proposal among 568 US (53% female) adolescents in the eighth grade (age ranging from 13–15 years), utilising a longitudinal design. Cyberbullying victimisation was related positively to restrictive mediation and Time 2 depression, anxiety and loneliness, while such associations were negative for co‐viewing mediation and instructive mediation. High levels of co‐viewing mediation and instructive mediation made the relationship of cyberbullying victimisation to Time 2 (1 year later) depression more negative. The results of this study are discussed in terms of the supportive role of parents in adolescents' digital technology use.
