As the prevalence of chronic kidney disease (CKD) increases, it is important to understand the self-care behavior of CKD patients.
To construct a CKD self-care scale and evaluate its metric properties.
Through literature review and clinical experience, question items were constructed and validated using item analysis. Factors analysis was used to validate the reliability and validity of the resultant questionnaire in a cross-sectional study.
Six subscales containing a total of 20 items were extracted from the original CKD self-care scale using item and exploratory factor analysis. After performing three-time model goodness of fit, only five subscales including regular medication (5 items), diet control (4 items), regular exercise (3 items), smoking habits (2 items), and blood pressure management (2 items) were included in the final scale. The total explained variance of the final subscales was 74.96%. The reliability of the scale was examined and found to be satisfactory. Each absolute factor loading value fell between .72 and .94. The Cronbach's alpha for the overall scale was .83 and those for the five subscales were .83, .83, .94, .81, and .87, respectively.
CONCLUSIONS / IMPLICATIONS FOR PRACTICE: Appropriate assessment tools that allow CKD health educators to evaluate the self-care behaviors of patients effectively are needed. The valid and reliable CKD self-care scale that was developed in the present study is able to assist CKD health educators to quickly evaluate the self-care behavior of patients and to make appropriate health plans.
随着慢性肾脏病（CKD）患病率的上升，了解CKD患者的自我护理行为非常重要。
构建CKD自我护理量表并评估其计量学特性。
通过文献回顾和临床经验构建问题条目，并采用项目分析进行验证。在一项横断面研究中，使用因素分析来验证所得问卷的信度和效度。
通过项目分析和探索性因素分析，从原始CKD自我护理量表中提取出6个分量表，共20个条目。在进行三次模型拟合优度检验后，最终量表仅包括5个分量表，即规律用药（5个条目）、饮食控制（4个条目）、规律运动（3个条目）、吸烟习惯（2个条目）和血压管理（2个条目）。最终分量表的总解释方差为74.96%。对量表的信度进行检验，结果令人满意。每个绝对因子载荷值在0.72至0.94之间。总量表的Cronbach's α系数为0.83，5个分量表的Cronbach's α系数分别为0.83、0.83、0.94、0.81和0.87。
结论/对实践的启示：需要合适的评估工具，以便CKD健康教育工作者能够有效评估患者的自我护理行为。本研究开发的有效且可靠的CKD自我护理量表能够帮助CKD健康教育工作者快速评估患者的自我护理行为，并制定适当的健康计划。
