Psychological safety has recently emerged as a central construct, strictly implicated in mental health and emotional well-being. The Neuroception of Psychological Safety Scale (NPSS) is the first scale designed to assess feelings of psychological safety from a multidimensional perspective. However, the robustness of its factorial structure requires further examination in large community samples, and evidence of construct validity along with measurement invariance across genders is scarce. The present study aimed to address these gaps through a comprehensive cross-validation approach. A community sample of 660 Italian adults, aged 18-65, completed self-report questionnaires including the NPSS, the Compassionate Engagement and Action Scale (CEAS), the Sussex-Oxford Compassion for Others (SOCS), and the Body Perception Questionnaire (BPQ). A three-factor model, i.e., , , and , demonstrated a good fit to the data in two random subsamples. Moreover, the measurement model was factorially invariant across genders. Model-based omega coefficients supported the internal consistency of the NPSS scores (ω ranged between 0.879 and 0.918). Zero-order correlations between NPSS subscales and CEAS, SOCS, and BPQ provided construct validity evidence. Additionally, inter-correlations between latent factors and Harman's single-factor test supported the discriminant validity of the NPSS dimensions. Overall, this study provided compelling evidence regarding the psychometric properties of the NPSS, demonstrating for the first time the invariance of its factorial structure across gender.
心理安全感最近已成为一个核心概念，与心理健康和情绪幸福感密切相关。心理安全感神经感知量表（NPSS）是首个旨在从多维度评估心理安全感的量表。然而，其因子结构的稳健性需要在大型社区样本中进一步检验，而且关于结构效度以及跨性别测量不变性的证据很少。本研究旨在通过全面的交叉验证方法来填补这些空白。一个由660名年龄在18至65岁之间的意大利成年人组成的社区样本完成了自我报告问卷，包括NPSS、同情参与和行动量表（CEAS）、苏塞克斯 - 牛津他人同情量表（SOCS）以及身体感知问卷（BPQ）。一个三因素模型，即[此处原文缺失具体因素内容]，在两个随机子样本中显示出与数据的良好拟合。此外，测量模型在性别间具有因子不变性。基于模型的欧米伽系数支持了NPSS分数的内部一致性（ω在0.879至0.918之间）。NPSS分量表与CEAS、SOCS和BPQ之间的零阶相关提供了结构效度证据。此外，潜在因子之间的相互关联以及哈曼单因素检验支持了NPSS维度的区分效度。总体而言，本研究为NPSS的心理测量特性提供了有力证据，首次证明了其因子结构在性别间的不变性。
