Methods: A descriptive, cross-sectional, and correlational design was used. The population consisted of players competing in the Turkish Handball Leagues during the 2024–2025 season, and 442 athletes participated using a non-probability sampling method. Data were collected via an online survey including a personal information form, the Psychological Well-Being Scale, the Buss–Perry Aggression Questionnaire, and the Exercise Addiction Inventory. Results: Psychological well-being showed a significant negative correlation with aggression (r = −0.242, p &lt; 0.001). Exercise addiction was positively associated with both psychological well-being (r = 0.212, p &lt; 0.001) and aggression (r = 0.105, p = 0.027). Mediation analysis indicated that exercise addiction significantly and partially mediated the relationship between psychological well-being and aggression (indirect effect 95% CI: 0.0246–0.1654). The direct effect of psychological well-being on aggression remained significant (β = −0.7093, p &lt; 0.001). Conclusion: Higher psychological well-being was associated with lower aggression among handball players, whereas exercise addiction was associated with both higher psychological well-being and higher aggression and emerged as a partial statistical mediator of this relationship. These findings may help inform future studies and preventive strategies focusing on athlete mental health and behavioral regulation. However, because of the cross-sectional design, causal inferences cannot be drawn.</dc:description><dc:publisher>Taylor and Francis Ltd.</dc:publisher><dc:date>2026</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/munzur/1307</dc:identifier><dc:identifier>https://doi.org/10.1080/00913847.2026.2667725</dc:identifier><dc:identifier>0091-3847</dc:identifier><dc:language>en</dc:language><dc:relation>Physician and Sportsmedicine</dc:relation><dc:rights>info:eu-repo/semantics/closedAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://munzur-rdlopen.rawdatalibrary.net/tr/items/munzur/1307</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
