[Correction Notice: An Erratum for this article was reported online in on Sep 15 2022 (see record 2023-01894-001). In the original article, the first name of Jacek Kolacz was misspelled as "Jakec" in the author byline and twice in the acknowledgments. In addition, the affiliations of Jacek Kolacz and Stephen W. Porges were incorrect. All versions of this article have been corrected.] Objective: Psychological safety is increasingly recognized as central to mental health, wellbeing and posttraumatic growth. To date, there is no psychometrically supported measure of psychological safety combining psychological, physiological and social components. The current research aimed to develop and establish the neuroception of psychological safety scale (NPSS), informed by Polyvagal Theory.
The study comprised of 3 stages: (a) item generation, (b) item reduction, and (c) assessment of factor structure and internal consistency. Exploratory and confirmatory factor analysis was conducted from 2 samples who completed a survey online (exploratory = 342, confirmatory = 455).
Initially, 107 items were generated. Item reduction and exploratory factor analysis resulted in a 29-item NPSS with subscales of compassion, social engagement and body sensations. The NPSS was found to have a consistent factor structure and internal consistency.
The NPSS is a novel measure of psychological safety which can be used across a range of health and social care settings. This research provides a platform for further work to support and enhance understandings of the science of safety through the measurement of psychological, relational and physiological components of safety. The NPSS will help shape new approaches to evaluating trauma treatments, relational issues and mental health concerns. Research to establish the convergent, discriminant and concurrent validity of the NPSS and to explore its use with diverse community and clinical populations is underway.

该研究包括三个阶段：（a）项目生成，（b）项目缩减，以及（c）因子结构和内部一致性评估。对两个在线完成调查的样本进行了探索性和验证性因子分析（探索性样本 = 342，验证性样本 = 455）。
最初生成了107个项目。经过项目缩减和探索性因子分析，得到了一个包含29个项目的NPSS，具有同情、社会参与和身体感觉等子量表。发现NPSS具有一致的因子结构和内部一致性。
NPSS是一种新颖的心理安全测量方法，可用于一系列健康和社会护理环境。本研究为进一步的工作提供了一个平台，以通过测量安全的心理、关系和生理成分来支持和增进对安全科学的理解。NPSS将有助于塑造评估创伤治疗、关系问题和心理健康问题的新方法。正在进行研究以确立NPSS的聚合效度、区分效度和同时效度，并探索其在不同社区和临床人群中的应用。（PsycInfo数据库记录（c）2024美国心理学会，保留所有权利）
