Abstract: This article attempts to compare similarities，differences and application prospects of three typical modes in which social workers participate in mental health services.These are specialized social worker training，governmental purchases，and setting up social worker departments in mental hospitals.Beijing，Chongqing and Shanghai were selected as representative sites.The first two modes are guided by government administrative departments，while the third mode is dominated by mental hospitals.In the aspect of future development of social worker team，specialized social worker training can expand the workforce in a short time.Governmental purchases can fully tap into the potential of existing social work organizations.Setting up social worker departments in mental hospitals makes the team more stable.In terms of service orientation，the government pays more attention to continuous service provision in the community，while social workers in mental hospitals provide services within hospitals as well as take on leadership roles in community work.The three models are neither isolated nor exclusive.All localities should make comprehensive explorations in accordance with its own economic level，social work resources and capability of mental hospitals，so as to promote the development of social work in mental health services.
