The impact of cyberbullying on mental health outcomes amongst university students: A systematic review

Cyberbullying is increasingly prevalent globally, particularly among young individuals. Cybervictims may be at an increased risk of adverse psychological outcomes. This systematic review aims to summarize the mental health effects of cyberbullying among college and university students. A systematic search of PubMed, Cochrane, and Embase databases was performed to identify studies reporting mental health effects of cybervictimization among college/university students until April 15, 2023. Risk of bias assessment was conducted using the National Institute of Health (NIH) tool. The review is registered on PROSPERO (CRD42023429187). Thirty-two studies involving 29,593 students were included. Depression showed a significant association with cyber-victimization in 16/20 studies (prevalence: 15-73%). Anxiety was significant in 12/15 studies (27-84.1%), stress in 3/3 studies (32-75.2%), and suicidal behavior in 4/9 studies (2-29.9%). Cybervictimization weakly but significantly correlated with lower self-esteem in 4 out of 6 studies (r = -0.152 to -0.399). Fear of perpetrators was reported in 2 out of 2 studies (12.8-16%), while decreased academic concentration/productivity was found in two studies (9-18%). Cybervictims were more likely to engage in substance abuse (adjusted odds ratio: 2.37 95% confidence interval: 1.02-5.49; p = 0.044). The majority of articles were of good quality (22/32). This review demonstrates a high prevalence of adverse mental health outcomes among cybervictims, including depression, anxiety, stress, and suicidal behavior. Based on these findings, we recommend that institutions of higher education worldwide introduce zero tolerance policies against cyberbullying, implement screening processes to identify affected students, and provide psychological therapy within their institutions.
