Current Status of Domestic Research on Non-Suicidal Self-Injury in Adolescents—CiteSpace-Based Visual Analysis

非自杀性自伤(Non-Suicidal Self-Injury, NSSI)已成为影响青少年身心健康发展的重要问题，日益引发教育界和心理健康领域的重视。为系统把握我国在该领域的研究进展，本研究采用文献计量学方法，以中国知网收录的相关文献为数据来源，检索时间跨度为建库至2024年6月。排除重复、不相关文献，最终纳入770篇符合标准的研究文献，并运用CiteSpace可视化分析工具，从年发文量、研究机构分布、核心作者网络以及关键词聚类等多个维度构建知识图谱。结果：近年相关文献年发文量大幅增长，研究热度渐升；国内安徽医科大学的万宇辉教授是影响力较高的作者，该校也是发文量最高的机构；从关键词分析，国内学者关注NSSI行为与精神疾病的关系，探讨心理特质、环境等因素对青少年NSSI行为的影响。Non-Suicidal Self-Injury (NSSI) has become an important issue affecting the physical and mental health development of adolescents, and has increasingly triggered the attention of the education and mental health fields. In order to systematically grasp the research progress in this field in China, this study adopted a bibliometric approach, using the relevant literature included in the China National Knowledge Infrastructure (CNKI) as the data source, and the search time span was from the establishment of the database to June 2024. Excluding duplicated and irrelevant literature, 770 research documents that met the criteria were finally included, and the CiteSpace visual analysis tool was used to construct a knowledge map from multiple dimensions, such as the annual publication volume, the distribution of research institutions, the core author network, and keyword clustering. Results: In recent years, the number of annual publications has increased dramatically, and the research intensity is increasing; Professor Wan Yuhui of Anhui Medical University is the author with high influence, and the university is also the institution with the highest number of publications; from the analysis of keywords, scholars in China are concerned about the relationship between NSSI behaviours and mental illnesses, and exploring the influence of psychological traits, environment and other factors on adolescents’ NSSI behaviours.
