: Psychological safety is essential for effective learning in high-fidelity simulation (HFS); however, no validated Japanese instrument currently exists to measure psychological safety among nursing students. This study aimed to translate the Psychological Safety in High-Fidelity Simulation (PS-HFS) scale into Japanese (PS-HFS-J) and evaluate its psychometric properties. : Following COSMIN guidelines, the PS-HFS was translated through forward and back translation, reviewed by an expert panel, and tested for face validity via pilot testing. The scale's reliability and validity were subsequently examined in 263 undergraduate nursing students using confirmatory factor analysis (CFA), Cronbach's alpha, and intraclass correlation coefficients (ICC). : CFA confirmed a good fit of the original four-factor model (CFI = 0.990, TLI = 0.988, RMSEA = 0.026). The scale demonstrated excellent internal consistency (Cronbach's α = 0.906 overall) and strong test-retest reliability (ICC range: 0.859-0.914). Content validity indices were also high (I-CVI = 0.80-1.00, S-CVI/Ave = 0.94). : The PS-HFS-J is a reliable, valid, and culturally adapted instrument for assessing psychological safety in Japanese nursing education. It can support educational research, curriculum development, and faculty training, contributing to safer and more effective simulation-based education. Future studies should examine its applicability across diverse educational levels and clinical contexts.
心理安全对于高保真模拟（HFS）中的有效学习至关重要；然而，目前尚无经过验证的日语工具来测量护理专业学生的心理安全。本研究旨在将高保真模拟中的心理安全（PS-HFS）量表翻译成日语（PS-HFS-J）并评估其心理测量特性。按照COSMIN指南，通过正向和反向翻译对PS-HFS进行翻译，由专家小组进行审查，并通过预试验测试其表面效度。随后，使用验证性因素分析（CFA）、克朗巴哈α系数和组内相关系数（ICC）对263名本科护理专业学生进行该量表的信效度检验。CFA证实了原始四因素模型的良好拟合度（CFI = 0.990，TLI = 0.988，RMSEA = 0.026）。该量表显示出出色的内部一致性（总体克朗巴哈α系数 = 0.906）和较强的重测信度（ICC范围：0.859 - 0.914）。内容效度指数也很高（I-CVI = 0.80 - 1.00，S-CVI/Ave = 0.94）。PS-HFS-J是一种可靠、有效且经过文化调适的工具，用于评估日本护理教育中的心理安全。它可以支持教育研究、课程开发和教师培训，有助于实现更安全、更有效的基于模拟的教育。未来的研究应考察其在不同教育水平和临床环境中的适用性。
