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.

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.

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.

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 (r_s=-0.160, -0.300, -0.177, -0.192; P<0.001) , serving as a criterion.

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.

糖尿病难以治愈且患病过程长，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。

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。

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诊治的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。

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负相关（r_s=-0.160、-0.300、-0.177、-0.192，P<0.001）。

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。
