Purpose: This study aims to reveal the mediating effect of social workers in improving residents’ well-being index. Methods: A total of 643 questionnaires were collected and the mediating effect was verified by SPSS PROCESS macro. Results: Community activities have a significant impact on residents’ sense of happiness. Social workers play a mediating role in some activities, but their overall explanatory power is limited and the perception of the mechanism is insufficient. It is necessary to enhance the quality of social workers’ intervention and institutional support and improve their professional functions and public recognition in the generation of residents’ happiness. Discussion: The mediating role of social workers varies in different types of community activities, with a relatively weak overall effect. Residents rely more on the experiences brought by the activities themselves to gain happiness, highlighting the issue of the perceivability and mechanism embedding of social work professional functions in practice.

华人社区的专业社工效果如何？

目的： 本研究旨在揭示社会工作者在改善居民幸福指数中的中介作用。方法： 共收集 643 份问卷，并通过 SPSS PROCESS 宏验证中介效应。结果： 社区活动对居民的幸福感有重大影响。社工在一些活动中起中介作用，但整体解释力有限，对机制的认知不足。有需要提升社工介入和机构支援的质素，提升社工的专业职能和公众对居民幸福感的认知度。讨论： 社会工作者的中介作用在不同类型的社区活动中有所不同，总体效果相对较弱。居民更依赖活动本身带来的体验来获得快乐，凸显了社会工作专业功能在实践中的可感知性和机制嵌入问题。
