Abstract：
OBJECTIVE: To evaluate the psychometric properties of the Advance Care Planning Readiness Scale (ACPRS-C) within the context of community-dwelling older adults with chronic diseases residing in suburban counties in China.
METHODS: Descriptive, cross-sectional survey.
METHODS: The research method employed in this study is characterized as a methodological study. Self-reported survey data were collected among community-dwelling older adults with chronic diseases residing in suburban counties in China. Including the following psychometric characteristics, item analysis was performed using the decision value method and Pearson\'s correlation analysis. Content validity was assessed through expert panel evaluation. The internal consistency of the questionnaire was determined by calculating Cronbach\'s alpha coefficient and corrected item-total correlation. Additionally, confirmatory factor analysis (CFA) was utilized to assess the construct validity of the ACPRS-C.
RESULTS: A total of 228 older adults participated in this psychometric study from August to October 2023. The item content validity index ranged from 0.80 to 1.00, while the scale content validity index was 0.945. The scale demonstrated excellent internal consistency (Cronbach\'s alpha = 0.931), and the correlation between items and total score was satisfactory. The structural validity was deemed robust (CFA model fit: chi-square/df = 1.121, comparative fit index = 0.992).
CONCLUSIONS: The ACPRS-C is a scale with strong psychometric properties to assess the ACP readiness within the context of community-dwelling older adults with chronic diseases residing in suburban counties in China. Its reliability and validity hold considerable significance for both research and clinical practice.

摘要：
目的：在中国郊县社区居住的患有慢性病的老年人中，评估预先护理计划准备量表（ACPRS-C）的心理测量学特性。
方法：描述性，横断面调查。
方法：本研究采用的研究方法是方法学研究。自我报告的调查数据是在中国郊县居住的社区居住的患有慢性病的老年人中收集的。包括以下心理测量特征，项目分析采用决策值法和Pearson相关分析。内容效度通过专家小组评估进行评估。通过计算Cronbach的α系数和校正的项目总相关性来确定问卷的内部一致性。此外,验证性因子分析(CFA)用于评估ACPRS-C的结构效度。
结果：从2023年8月至10月，共有228名老年人参加了这项心理测量学研究。项目内容效度指数为0.80~1.00,量表内容效度指数为0.945。该量表表现出优异的内部一致性(Cronbach'sα=0.931)，项目与总分的相关性令人满意。结构有效性被认为是稳健的(CFA模型拟合:卡方/df=1.121,比较拟合指数=0.992)。
结论：ACPRS-C是一种具有强大心理测量特性的量表，用于评估居住在中国郊县的社区居住的患有慢性病的老年人的ACP准备情况。其信度和效度对研究和临床实践都具有重要意义。
