Abstract: Peer support as an important approach to mental health recovery has gained increasing global attention in recent years. On the basis of a review of the development of community-based peer support services in the United States and Australia, combined with an examination of local practices in China, this study analyzes the current status and future directions of peer support services in the Chinese context. In the United States, peer support services have been established, forming a professionalized framework that includes training, certification, and career development, with strong policy and insurance support. In Australia, peer support has been widely integrated into community mental health services and has achieved institutionalization and standardization driven by government funding and collaboration with social organizations. China′s peer support services, however, remain at the exploration and promotion stage, with notable gaps in standardized training, professional certification, career pathways, and policy safeguards. Looking ahead, the development of a systematic and multi-stakeholder collaboration framework of community-based peer support services, guided by national policies, is essential for enhancing the professionalism, standardization, and sustainability of services, thereby contributing to the continuous improvement of China’s community-based mental health rehabilitation system.
