Digital aggression (DA), or the use of information communication technologies to inflict harm on others, is an emerging public health crisis. Targets of DA experience increased anxiety, depression, aggression, and higher rates of suicidal ideation and attempts. There is thus a clear need to uncover the origins of DA. A handful of studies have identified contextual features that increase DA, most notably anonymity. Critically, however, research in this context has rarely evaluated different aspects of anonymity, specifically technical versus social anonymity or self- versus other-anonymity. It has also frequently relied on potentially problematic self-report assessment techniques. The current paper sought to better understand the role of anonymity in DA with a systematic review of the relevant literature. While the systematic review did highlight a significant relationship between perpetrator self-anonymity and DA, we also uncovered evidence of a more complex and nuanced relationship between anonymity and DA than was expected, including the need to jointly consider positive cyberbullying attitudes and related constructs. Implications for prevention and intervention efforts aimed at reducing DA are discussed. • Anonymity is an important contextual factor in digital aggression (DA). • Little research has evaluated different aspects of anonymity (technical vs. social and self vs. other). • A systematic review on the role of anonymity in DA was conducted. • The review suggested a significant relationship between DA and anonymity broadly-defined. • Implications for DA intervention and prevention strategies are discussed.

Cyberbullying victimisation is a form of abuse through electronic means that can have a negative impact on the mental health of young people. Ethnic minority youth might be particularly affected by the impact of cyberbullying victimisation, as it cumulates with other life stressors. The present systematic review aimed to explore the mental health outcomes of cyberbullying victimisation among ethnic minority young people. A database search was conducted on PsycInfo, Academic Search Complete, ERIC, Scopus, and Web of Science. A total of 1258 articles was scanned, and 26 papers met the eligibility criteria for this review. A quality assessment of the eligible studies was carried out. Sample size of the included studies ranged between 118 and 15,425; most studies were quantitative and only 9 adopted a longitudinal design. Findings of the included studies showed that cybervictimised ethnic minority young people manifest mental health problems in terms of depression, anxiety, substance abuse and suicidal ideation. Cybervictimisation may constitute a risk factor for developing mental health problems in this vulnerable population, though confounding variables were not controlled for in most studies. Furthermore, findings are inconsistent among studies, which could be due to methodological gaps in the extant literature. Implications for research, policy and legislation are outlined. • Ethnic minority youth reported mental health problems following cybervictimisation. • Findings were mixed as to whether mental health issues varied based on ethnicity. • Most of the included studies reported a medium score on the quality review tool.
