炎症性肠病(IBD)是一组病因和发病机制尚不明确的慢性非特异性肠道炎性疾病。我国2012年数据显示IBD的发病率在1.4/10万～11.4/10万之间，近年呈明显上升趋势；复发率高达50%～70%，发病高峰年龄为18～35岁，疾病迁延难愈，严重影响生活质量。自我管理是慢病管理的新理念，国内IBD自我管理研究仍处于起步阶段，仅见一些碎片化报道。本研究基于“态度-社会影响-自我效能模型”和“慢病管理分层理论”为指导，结合本课题前期研究和文献分析的结果，确定IBD自我管理核心要素，明确IBD患者分层支持即初级、中级、高级自我管理三个等级。采用结构方程模型分析法，建立各因子与患者自我管理行为之间的相互关系，构建IBD患者自我管理分层支持模型。应用类实验不对等对照组设计研究对该模型进行验证，阐明其应用效果和机制规律。实现患者由消极应对向主动自我管理、积极参与决策的转变，以提高生活质量为终期目标。

Inflammatory bowel disease (IBD) is a group of chronic non-specific intestinal inflammatory diseases with unclear etiology and pathogenesis. According to the data of 2012 in China, the incidence of IBD was between 1.40/100,000 and 11.4/100,000, showing an obvious rising trend in recent years. The recurrence rate is high to 50-70%, and the peak age of onset is 18-35 years old. The disease has been listed as one of the modern intractable diseases by WHO. Self-management is a new concept of chronic disease management. Domestic research on IBD self-management is still in its infancy, and only some fragmented and unsystematic reports have been found. Based on the "attitude-social-influence-self-efficacy model" and "chronic disease management hierarchical theory" as the guidance, combined with the data basis of the previous research and the results of literature analysis, the core elements of IBD self-management were determined, and the hierarchical support for IBD patients was defined to include the primary, intermediate and advanced levels of self-management. The relationship between each factor and patients' self-management behavior was established by structural equation model (SEM) analysis, and a hierarchical support model for IBD patients' self-management was constructed. The model was verified by the design study of the asymmetric control group in the applied experiment, and its application effect and mechanism were clarified. It aims to realize the patients' transformation from passive coping to active self-management and active participation in clinical decision-making, and finally achieve the final goal of improving the life quality of IBD patients.
