Self-management has been associated with positive health outcomes among adults with chronic kidney disease (CKD). Perceived disease-related self-efficacy (DSE) is considered a critical component in the successful self-management of chronic disease. A valid and reliable instrument for measuring CKD patients' self-efficacy is needed. This study aims to develop and test a new instrument to measure the DSE of patients with early stage CKD.
A total of 594 Taiwanese patients with early stage CKD recruited from two medical centers and one regional hospital in southern Taiwan completed the questionnaire. The CKD self-efficacy (CKD-SE) was evaluated using exploratory factor analyses (EFA) and measures of reliability.
EFA identified four distinct factors with loadings ranging from 0.557 to 0.970: autonomy, self-integration, problem solving and seeking social support, accounting for 64.348% of the total variance. Cronbach's alpha coefficients for the subscales ranged from 0.843 to 0.901.
This promising 25-item CKD-SE instrument can be used for the early identification of patients with low DSE, thus allowing the development of interventions to help these patients attain an appropriate level of DSE.
自我管理与慢性肾脏病（CKD）成人的健康结果呈正相关。疾病相关自我效能感（DSE）被认为是成功管理慢性疾病的关键组成部分。需要一种有效的、可靠的工具来衡量 CKD 患者的自我效能感。本研究旨在开发和测试一种新的工具，以衡量早期 CKD 患者的 DSE。
台湾南部的两家医疗中心和一家地区医院共招募了 594 名早期 CKD 患者完成问卷。使用探索性因素分析（EFA）和可靠性测量来评估 CKD 自我效能感（CKD-SE）。
EFA 确定了四个具有 0.557 至 0.970 之间的负荷的不同因素：自主性、自我整合、解决问题和寻求社会支持，占总方差的 64.348%。子量表的克朗巴赫α系数范围为 0.843 至 0.901。
这种有前途的 25 项 CKD-SE 工具可用于早期识别自我效能感低的患者，从而可以制定干预措施帮助这些患者达到适当的自我效能感水平。
