Abstract：
OBJECTIVE: The need for long-term treatment and frequent visits to treatment centers for hemodialysis can lead to psychological problems such as Uncertainty about Disease and Treatment (UC about D&T) in patients with chronic kidney failure. In order to understand uncertainty about disease and treatment and to plan for preventive measures and care interventions in various dimensions, there is a need for reliable and valid tools. The present study was conducted to design and psychometrically evaluate the Uncertainty about Disease and Treatment Scale (UC about D&TS) in patients undergoing hemodialysis.
METHODS: This study is of a methodological type and conducted in two stages. The first stage included a deductive (literature review) and an inductive approach (face-to-face interviews). In the second stage, psychometric indices of the UC about D&TS, including face validity (qualitative-quantitative), content validity (qualitative-quantitative), construct validity (exploratory factor analysis), and reliability (using Cronbach\'s alpha and McDonald\'s omega) were examined.
RESULTS: In the literature review stage, 66 items were extracted, and in the qualitative stage, 48 items were extracted. After merging similar items, 29 items were entered into the psychometric process. No items were removed in the face and content validity stages. In the construct validity stage, five factors were extracted, including self-uncertainty, uncertain situation, uncertain future, uncertainty of treatment outcomes, and information uncertainty, which constituted a total of 82.16% of the total variance. In this stage, five items were removed from the study due to a corrected item-total correlation below 0.32, and four items were removed due to cross-loading. The α and Ω were calculated as 0.828 and 0.818, respectively. The measurement stability and standard error of measurement were estimated at 0.977 and 2.019, respectively.
CONCLUSIONS: The results showed that the UC about D&TS is a valid and reliable measure for patients undergoing hemodialysis. This scale is specifically designed to measure UC about D&T in hemodialysis patients, and it is recommended that healthcare providers (Hcps) use this scale in follow-up visits.

摘要：
目的：需要长期治疗和经常到血液透析治疗中心就诊会导致慢性肾衰竭患者的心理问题，如疾病和治疗不确定感（UCaboutD&T）。为了了解疾病和治疗的不确定性，并计划各种方面的预防措施和护理干预措施，需要可靠和有效的工具。本研究旨在设计和心理评估血液透析患者的疾病和治疗不确定性量表（UCaboutD＆TS）。
方法：本研究属于方法学类型，分两个阶段进行。第一阶段包括演绎（文献综述）和归纳方法（面对面访谈）。在第二阶段,UC关于D&TS的心理测量指数，包括面部效度(定性-定量)，内容效度(定性-定量)，结构效度(探索性因子分析)，和可靠性(使用克朗巴赫的阿尔法和麦当劳的欧米茄)进行了检查。
结果：在文献综述阶段，提取了66个项目，在定性阶段，提取了48个项目。合并类似项目后，29个项目被输入到心理测量过程中。在正面和内容有效性阶段没有删除任何项目。在结构有效性阶段，提取了五个因素，包括自我不确定性，不确定的情况,不确定的未来,治疗结果的不确定性，和信息不确定性，占总方差的82.16%。在这个阶段,5个项目由于校正的项目总相关性低于0.32而从研究中移除,4个项目由于交叉负荷而被移除.α和Ω分别计算为0.828和0.818。测量稳定性和测量标准误差分别估计为0.977和2.019。
结论：结果表明，关于D＆TS的UC是血液透析患者的有效且可靠的措施。该量表专门设计用于测量血液透析患者中关于D&T的UC，建议医疗保健提供者（Hcps）在随访中使用该量表。
