Nurses are one of the most critical members of advance care planning (ACP) discussion. The evaluation of ACP self-efficacy is of great significance for developing targeted ACP interventions among clinical nurses and update their professional roles. However, there are few instruments to evaluate their ACP self-efficacy in mainland China. The purpose of this study was to translate the ACP self-efficacy scale into Chinese and evaluate its psychometric properties among clinical nurses.
A methodological study of the translation and validation of the ACP self-efficacy scale was conducted from January to March 2022. It involved three phases: (1) the translation and revision of the scale; (2) the exploration and evaluation of the item (n = 436); (3) the psychometric evaluation of the scale (n = 674).
After a rigorous translation and revision, the ACP self-efficacy scale with three dimensions and 16 items was finally formed. In this study, the critical ratios of the item ranged from 8.226 to 17.499, and the item-total correlation coefficients ranged from 0.437 to 0.732, and the factor loadings of the item ranged from 0.638 to 0.882. The content validity index of the scale was 0.946. Supported by the eigenvalues, the three-factor structure explained the cumulative 61.131% of the overall variance. As the results of confirmatory factor analysis, all the recommended fitting indexes were appropriate. The average variance extracted values ranged from 0.570 to 0.756, and the composite reliability values ranged from 0.858 to 0.925. The total Cronbach's α coefficient, split-half reliability coefficient and test-retest reliability coefficient of the scale were 0.896, 0.767 and 0.939, respectively.
The Chinese version of ACP self-efficacy scale was successfully introduced into China, showing good psychometric properties among clinical nurses, and can effectively assess the ACP self-efficacy. Also, the scale can provide nursing educators with a significant strategy to develop ACP educational procedure and post-intervention measures for clinical nurses to improve nurse-led ACP practice.
护士是预先医疗照护计划（ACP）讨论中最重要的成员之一。评估 ACP 自我效能对制定针对临床护士的 ACP 干预措施并更新他们的专业角色具有重要意义。然而，在中国，很少有工具可以评估他们的 ACP 自我效能。本研究旨在将 ACP 自我效能量表翻译成中文，并评估其在临床护士中的心理测量特性。
2022 年 1 月至 3 月，进行了 ACP 自我效能量表的翻译和验证的方法学研究。它涉及三个阶段：（1）量表的翻译和修订；（2）项目探索和评估（n=436）；（3）量表的心理测量评估（n=674）。
经过严格的翻译和修订，最终形成了具有三个维度和 16 个项目的 ACP 自我效能量表。在本研究中，项目的临界比范围为 8.226 至 17.499，项目总分相关系数范围为 0.437 至 0.732，项目的因子负荷范围为 0.638 至 0.882。量表的内容效度指数为 0.946。支持特征值，三因素结构解释了总体方差的 61.131%的累积方差。验证性因素分析的结果表明，所有推荐的拟合指标都合适。平均方差提取值范围为 0.570 至 0.756，组合可靠性值范围为 0.858 至 0.925。量表的总 Cronbach's α 系数、半分信度系数和重测信度系数分别为 0.896、0.767 和 0.939。
ACP 自我效能量表的中文版成功引入中国，在临床护士中表现出良好的心理测量特性，能有效评估 ACP 自我效能。此外，该量表可以为护理教育者提供一种重要的策略，为临床护士制定 ACP 教育程序和干预后措施，以提高护士主导的 ACP 实践。
