In the field of psychological research, researchers have been exploring a relatively stable path that can promote good interpersonal relationships and increase positive emotions. Empathy is a new field in emotion research and has gradually become a hot issue in empathy research at home and abroad. However, there are many problem families in the current society that are difficult to achieve positive emotions and need the help of society. At present, casework research has gradually become an important means to solve social problems, but the current work efficiency is relatively low, and the mobilization of the enthusiasm of all parties is also relatively weak. In order to solve these problems, this paper proposes a casework solution based on social network analysis empathy theory, aiming at solving some difficult social problems through the cooperation of all social parties. The method of this paper is to study the application of social network analysis, analyze the network community, and then propose the moderating effect of empathy traits on casework. These methods allow social workers to fully understand the social structure in social networks and feel the role of empathy theory in promoting their work. This article draws on a general methodology for applying casework through actual casework of caregivers of intellectually disabled youth, children with autism, and the elderly with orphans. The results show that the solution proposed in this paper can effectively improve the client’s nonverbal communication behavior, and the improvement rate reaches 65.1%.
