Abstract

Objective: There is emerging evidence that first responders, like military personnel, are at risk for exposure to potentially morally injurious events. However, studies examining expressions of moral injury in first responders are nascent, in large part due to the limited number of measures validated for use in this population. To address this gap, the present study sought to investigate the psychometric properties of the Expressions of Moral Injury Scale-Military Version (EMIS-M) in a sample of first responders.

Method: The psychometric properties of the EMIS-M were investigated in a sample of 228 first responders to determine reliability, convergent validity, discriminative validity, and divergent validity. In addition, confirmatory factor analysis was conducted to test the bifactor model identified in a veteran sample (Currier et al., 2018).

Results: Results yielded an excellent fit for the bifactor model with correlated self-directed and other-directed subscales identified in the EMIS-M development study. In addition, the measure evidenced strong reliability, convergent validity, discriminative validity, and divergent validity.

Conclusions: The findings of the present study suggest that the Expressions of Moral Injury Scale-First Responder Version is a psychometrically sound measure capable of assessing self- and other-directed expressions of moral injury in first responders. The significance of these findings to our understanding of moral injury in first responders and their implications for future research are discussed.

在急救人员样本中检验道德伤害表达量表的心理测量特性。

目的：有新的证据表明，急救人员和军人一样，都有可能遭遇潜在的精神伤害事件。然而，对第一反应者道德伤害表达的研究还刚刚起步，这在很大程度上是由于经过验证可用于这一人群的测量方法数量有限。为了填补这一空白，本研究试图在第一反应者样本中调查道德伤害表达量表-军事版（EMIS-M）的心理测量特性：方法：在 228 名急救人员样本中调查了 EMIS-M 的心理测量特性，以确定其信度、收敛效度、区分效度和发散效度。此外，还进行了确认性因素分析，以检验在退伍军人样本中确定的双因素模型（Currier 等人，2018 年）：结果表明，双因素模型与EMIS-M开发研究中确定的相关自我导向和他人导向子量表非常契合。此外，该量表还具有很强的信度、收敛效度、区分效度和发散效度：本研究的结果表明，道德伤害表达量表--急救人员版是一种心理测量方法，能够评估急救人员自我和他人导向的道德伤害表达。本文讨论了这些发现对我们理解急救人员道德伤害的意义以及对未来研究的影响。(PsycInfo Database Record (c) 2024 APA，保留所有权利）。

期刊介绍： Psychological Trauma: Theory, Research, Practice, and Policy publishes empirical research on the psychological effects of trauma. The journal is intended to be a forum for an interdisciplinary discussion on trauma, blending science, theory, practice, and policy. The journal publishes empirical research on a wide range of trauma-related topics, including: -Psychological treatments and effects -Promotion of education about effects of and treatment for trauma -Assessment and diagnosis of trauma -Pathophysiology of trauma reactions -Health services (delivery of services to trauma populations) -Epidemiological studies and risk factor studies -Neuroimaging studies -Trauma and cultural competence
