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.

摘要： 本文从社会工作者（社工）参与精神卫生服务角度比较专项社工人才培养、购买社工组织服务、精神卫生医疗机构社工岗位设置三种模式的异同及应用前景。选取了北京市、重庆市、上海市作为典型模式代表。前两种模式由政府行政部门主导，第三种模式由医疗机构主导；在社工队伍发展方面，专项社工人才培养能够短期内充实队伍，购买社工组织服务能够充分发挥现有社工队伍的作用，精神卫生医疗机构设置社工岗位使队伍更稳定；在服务侧重方面，政府购买服务更注重在社区持续开展服务，精神卫生医疗机构内的社工主要在院内开展服务，并承担对社区精神卫生社工服务的带动指导作用。三种模式并不是孤立互斥的，各地应根据经济水平、社会组织资源、医疗机构实力等实际情况进行综合探索，推动精神卫生工作中社会服务的发展。
