军事人员可能会遇到道德上有伤害的事件，这些事件会导致情感、社会和精神上的痛苦，这些痛苦超越和/或与心理健康诊断重叠（例如，创伤后应激障碍 [PTSD]）。道德伤害（MI）科学研究的进步和潜在的临床创新需要多样化的测量方法。本研究借鉴了 Currier 等人 (2017) 对道德伤害量表军事版 (EMIS-M) 的心理测量评估中双因素模型的结果，利用两个有战区服役历史的退伍军人样本验证了该工具的四项简短形式。也就是说，尽管项目数量减少，但 EMIS-M-Short Form (SF) 与完整版本一样，与理论上相关的结构（例如 PTSD 以及与道德和最终意义的斗争）产生了良好的内部一致性和可比较的收敛有效性水平。尽管区分自我导向和其他导向形式的 MI 可能有用，但因子分析结果进一步表明，EMIS-M-SF 最好用一维因子模型来概念化，该模型可能允许对 MI 相关结果进行一般评估。总体而言，这些初步结果表明 EMIS-M-SF 有望作为与可能的 MI 相关的总体结果的简短、可靠且有效的评估。
Military personnel may encounter morally injurious events that lead to emotional, social, and spiritual suffering that transcend and/or overlap with mental health diagnoses (e.g., post-traumatic stress disorder [PTSD]). Advancement of scientific research and potential clinical innovation for moral injury (MI) requires a diversity of measurement approaches. Drawing on results from the bifactor model in Currier et al.'s (2017) psychometric evaluation of the Expressions of Moral Injury Scale-Military version (EMIS-M), this study validated a four-item short form of the instrument with two samples of veterans with a history of war-zone service. Namely, despite the reduced number of items, the EMIS-M-Short Form (SF) yielded favourable internal consistency and comparable levels of convergent validity with theoretically related constructs (e.g., PTSD and struggles with morality and ultimate meaning) as the full-length version. Notwithstanding the possible utility of distinguishing between self- and other-directed forms of MI, factor analytic results further revealed that the EMIS-M-SF was best conceptualized with a unidimensional factorial model that might allow for a general assessment of MI-related outcomes. Overall, these initial results suggest that the EMIS-M-SF may hold promise as a short, reliable, and valid assessment of overall outcomes related to a possible MI.
