This systematic review synthesizes findings on female-to-female aggression and its mental health consequences across the lifespan. Although bullying among females represents a significant public health concern, the literature has historically underexamined how relational forms of aggression, including social exclusion, gossip, and peer manipulation, affect women over time. Three research questions organized the review: (a) How do negative social groups affect women? (b) What are the longer-term consequences of childhood bullying for women in adulthood? (c) What outcomes are associated with aggressive female social dynamics? Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework, a systematic search was conducted across PubMed/MEDLINE, PsycINFO (accessed via EBSCOhost), Google Scholar, ScienceDirect, JSTOR, and SciSpace. Inclusion criteria required articles to be peer-reviewed, published between 1992 and 2024, focused on female participants or gender-disaggregated data, and reporting mental health outcomes related to bullying or hostile social dynamics. A total of 42 studies met inclusion criteria, comprising 27 quantitative, 14 qualitative, and 1 mixed-method study.
