Methods: Using Spring 2025 data from the Health and Peer Relations Study, we examined whether gender identity and sexual orientation moderated the association between bullying and mattering among Canadian youth in Grades 7\u201312 (N = 54,181; racially\/ethnically diverse = 65.2%, sexually diverse = 14.8%, gender\u00a0diverse = 3.5%), controlling for grade and race\/ethnicity. Results: After controlling for covariates, the three-way interaction between bullying, gender identity, and sexual orientation was statistically significant (p = 0.042). Bullying was negatively associated with mattering across most groups, and the association was strongest among straight girls, while associations were largely similar across other groups. In contrast, average mattering followed a clear social gradient wherein straight girls and boys reported the highest levels, and sexually and\/or gender diverse youth reported the lowest. Conclusions: Bullying is associated with lower mattering among most youth. However, socially advantaged youth reported stronger associations between bullying and mattering, while socially marginalized youth reported lower mattering regardless of bullying exposure. Findings highlight the importance of addressing youth bullying and underlying drivers of social inequities in mattering.<\/jats:p>","DOI":"10.3390\/children13081066","type":"journal-article","created":{"date-parts":[[2026,8,11]],"date-time":"2026-08-11T08:09:36Z","timestamp":1786435776000},"page":"1066","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Bullying Victimization and Mattering: An Analysis of Adolescent Gender Identity and Sexual Orientation"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-7067-2936","authenticated-orcid":false,"given":"Sarah","family":"Hobson","sequence":"first","affiliation":[{"name":"School of Psychology, Faculty of Social Science, University of Ottawa, 120 University Private, Ottawa, ON K1N 6N5, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1398-7572","authenticated-orcid":false,"given":"Amanda","family":"Krygsman","sequence":"additional","affiliation":[{"name":"Counselling Psychology, Faculty of Education, University of Ottawa, 145 Jean-Jacques-Lussier Private, Ottawa, ON K1N 6N5, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6070-3689","authenticated-orcid":false,"given":"Heather","family":"Brittain","sequence":"additional","affiliation":[{"name":"Counselling Psychology, Faculty of Education, University of Ottawa, 145 Jean-Jacques-Lussier Private, Ottawa, ON K1N 6N5, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-4639-2707","authenticated-orcid":false,"given":"Anjalika","family":"Khanna Roy","sequence":"additional","affiliation":[{"name":"Counselling Psychology, Faculty of Education, University of Ottawa, 145 Jean-Jacques-Lussier Private, Ottawa, ON K1N 6N5, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9058-7276","authenticated-orcid":false,"given":"Tracy","family":"Vaillancourt","sequence":"additional","affiliation":[{"name":"School of Psychology, Faculty of Social Science, University of Ottawa, 120 University Private, Ottawa, ON K1N 6N5, Canada"},{"name":"Counselling Psychology, Faculty of Education, University of Ottawa, 145 Jean-Jacques-Lussier Private, Ottawa, ON K1N 6N5, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"908","DOI":"10.1111\/jora.12678","article-title":"Dynamics of identity development in adolescence: A decade in review","volume":"31","author":"Branje","year":"2021","journal-title":"J.
