As social virtual reality (social VR) platforms increasingly captivate users worldwide, questions arise about how digitally mediated self-representation affects psychological health. This study investigates how avatar characteristics-specifically perceived avatar appearance similarity and perceived attractiveness-shape users' well-being in social VR, with a focus on the mediating role of avatar identification. Drawing on two-wave longitudinal data collected over a three-month period from 486 VRChat users, the findings reveal that perceived avatar attractiveness was positively associated with users' satisfaction with virtual life through enhanced avatar identification. However, perceived similarity did not exert a significant positive influence. Notably, while identification with attractive avatars supported virtual well-being, avatar attractiveness was also negatively associated with self-acceptance, suggesting a complex relationship between virtual self-presentation and mental health outcomes. These results highlight the critical psychological processes through which virtual identity communication is associated with users' well-being and self-perception. This study calls for greater attention within health communication research to the ways avatar-mediated interactions in emerging digital environments can both support and challenge mental health.
