Clinical decision making (CDM) is a cornerstone skill for nurses. Self-confidence and anxiety affect the learning and adeptness of CDM. This study aimed to develop and test a quantitative tool to assess undergraduate nursing students' self-confidence and anxiety during CDM. The 27-item Nursing Anxiety and Self-Confidence with Clinical Decision Making (NASC-CDM) scale is a 6-point, Likert-type tool with two subscales. Two samples of prelicensure associate and baccalaureate nursing students participated in the pilot (n = 303) and main testing (n = 242) phases of the study. Construct validity assessment, using exploratory factor analysis, produced a stable three-dimensional scale. Convergent validity assessment produced positive, moderate, and statistically significant correlations of the tool sub-scales with two existing instruments. Internal consistency reliability was assessed for each subscale (self-confidence, α = .97; anxiety, α = .96). The NASC-CDM scale may be a useful assessment tool for nurse educators to help novice clinicians improve CDM skills.
临床决策（CDM）是护士的一项核心技能。自信和焦虑会影响 CDM 的学习和熟练程度。本研究旨在开发和测试一种评估本科护理学生在 CDM 期间自信心和焦虑的定量工具。护理焦虑和临床决策自信心量表（NASC-CDM）共有 27 个项目，采用 6 点 Likert 量表，包含两个分量表。在研究的试点（n = 303）和主要测试（n = 242）阶段，两个样本的护理学生（副学士和学士学位）参与了研究。使用探索性因素分析进行的结构有效性评估产生了稳定的三维量表。工具子量表与两个现有工具的相关性呈正相关、中等且具有统计学意义。每个子量表的内部一致性信度（自信心，α =.97；焦虑，α =.96）都得到了评估。NASC-CDM 量表可能是护士教育者的一种有用的评估工具，可帮助新手临床医生提高 CDM 技能。
