Objective

To conduct a systematic review and meta-analysis and estimate the economic costs attributable to child and adolescent bullying victimization in Australia.

Method

The costs of bullying victimization were measured from a societal perspective that accounted for costs associated with health care, education resources, and productivity losses. A prevalence-based approach was used to estimate the annual costs for Australians who experienced bullying victimization in childhood and adolescence. This study updated a previous systematic review summarizing the association between bullying victimization and health and nonhealth outcomes. Costs were estimated by calculating population attributable fractions to determine the effects of bullying victimization on increased risk of adverse health outcomes, such as anxiety disorders, depressive disorders, intentional self-harm, and tobacco use. A top-down approach to cost estimation was taken for all outcomes of interest except for costs incurred by educational institutions and productivity losses of victims’ caregivers, for which a bottom-up cost estimation was applied.

Results

Annual costs in Australian dollars (AUD) in 2016 on health and nonhealth outcomes attributable to child and adolescent bullying victimization were estimated at AUD $763 million: AUD $750 million for health system costs with AUD $147 million for anxiety disorders, AUD $322 million for depressive disorders, AUD $57 million for intentional self-harm, and AUD $224 million for tobacco use; AUD $7.5 million for productivity losses of victims’ caregivers; and AUD $6 million for educational services.

Conclusion

The findings from this study suggest a substantial annual cost to Australian society as a result of bullying victimization with more than 8% of annual mental health expenditure in Australia estimated to be attributable to bullying victimization.
