Abstract: Background Diabetes mellitus is difficult to cure and has a long process . The level of self-care is crucial for determining the regression and health outcomes of patients with diabetes. A comprehensive and theory-based tool is urgently needed to assess the level of self-care of diabetes. In this way，the self-care of patients with diabetes can be kept up to date and accurate nursing care can be carried out. Objective To examine the psychometric properties of the Chinese version of Self-care of Diabetes Inventory（SCODI），and provide a scientifically validated assessment tool for the self-care of Chinese patients with diabetes. Methods The Brislin Translation Model was used for translation and cultural adaptation of the English version of the SCODI into Chinese. A total of 261 adult patients with diabetes were enrolled using a consecutive sampling method at the First Affiliated Hospital and the Affiliated Sir Run Run Hospital of Nanjing Medical University from December 2022 to June 2023. Data were collected using a self-developed general information questionnaire and the Chinese version of SCODI. Exploratory factor analysis was used to assess the structural validity. Cronbach's α，split-half reliability and composite reliability were used to describe the reliability. Glycosylated hemoglobin was used as a criterion to assess the criterion-related validity. Spearman's rank correlation analysis was used to examinate the correlation between the Chinese version of SCODI score and glycosylated hemoglobin. Results The Chinses version of SCODI contained 4 dimensions and 40 items：self-care maintenance score（75.94±13.15），self-care monitoring score（70.65±18.71），self-care management score（69.16±18.24），and self-care confidence score（85.41±13.63）. In the self-care maintenance dimension，4 factors were identified：complication screening behaviors，exercise behaviors，hygienic care behaviors and diet-medication behaviors. The self-care monitoring dimension had 2 factors：physical monitoring and symptom identification. The self-care management dimension included 2 factors：autonomous behaviors and counseling behaviors. Two factors were extracted from the self-care confidence dimension：monitoring and managing confidence，health maintenance confidence. The Cronbach's α，split-half reliability and composite reliability values for the total scale were 0.915，0.836 and 0.912，respectively. The Cronbach's α for the four dimensions were 0.709-0.908. A significantly negative correlation was observed between each subscale and glycosylated hemoglobin（rs=-0.160，-0.300，-0.177，-0.192；P<0.001），serving as a criterion. Conclusion Based on the middle-range theory of self care of chronic illness，the Chinese version of SCODI exhibits strong psychometric properties，making it a valid and reliable instrument for evaluating self-care of Chinese patients with diabetes.

摘要： 背景 糖尿病难以治愈且患病过程漫长，自我护理水平对糖尿病患者的疾病转归和健康结局至关重要，迫切需要理论指导下内容全面的糖尿病自我护理水平评估工具，以便及时掌握患者的自我护理情况，对应开展精准化护理。目的 本研究旨在对糖尿病自我护理指数量表（SCODI）进行汉化，并检验中文版SCODI的信效度，为中国糖尿病患者提供自我护理的科学评估工具。方法 采用Brislin翻译模式将原版SCODI翻译成中文，并进行文化调试。采用连续抽样法，选取 2022 年 12 月—2023 年 6 月南京医科大学第一附属医院和附属逸夫医院的 261 例糖尿病患者进行调查。使用研究者自行编制的一般资料调查表和汉化修订之后的中文版 SCODI 进行资料收集。采用探索性因子分析评估中文版SCODI的结构效度。采用 Cronbach's α系数、折半信度和组合信度描述量表的信度。本研究以生理指标糖化血红蛋白作为效标检验中文版 SCODI 的效标关联效度，采用 Spearman 秩相关分析探讨中文版 SCODI 得分与糖化血红蛋白水平的相关性。结果 中文版 SCODI 包含 4 个分量表，共 40 个条目：自我护理维持得分为（75.94±13.15）分，自我护理监测得分为（70.65±18.71）分，自我护理管理得分为（69.16±18.24）分，自我护理信心得分为（85.41±13.63）分。自我护理维持分量表提取出 4 个因子（并发症筛查、运动锻炼、卫生保健、饮食服药），自我护理监测分量表提取出 2 个因子（身体监测、症状识别），自我护理管理分量表提取出 2 个因子（自主管理、咨询管理），自我护理自信分量表提取出 2 个因子（监测与管理信心、健康维持信心）。中文版 SCODI 总量表的 Cronbach's α 系数为 0.915，折半信度为 0.836，组合信度为 0.912，4 个分量表的 Cronbach's α 系数为 0.709~0.908。以生理指标糖化血红蛋白作为效标，各量表得分与糖化血红蛋白水平呈显著负相关（rs=-0.160、-0.300、-0.177、-0.192，P<0.001）。结论 基于慢性病自我护理中层理论开发的中文版 SCODI 具有良好的信度和效度，可用于评估中国糖尿病患者的自我护理水平。
