Moral injury (MI) is defined as the profound psychological distress experienced in response to perpetrating, failing to prevent, or witnessing acts that transgress personal moral standards or values. Given the elevated risk of adverse mental health outcomes in response to exposure to morally injurious experiences in military members, it is critical to implement valid and reliable measures of MI in military populations. We evaluated the reliability, convergent, and discriminant validity, as well as the factor structure of the commonly used Moral Injury Events Scale (MIES) across two separate active duty and released Canadian Armed Forces samples. In Study 1, convergent and discriminant validity were demonstrated through correlations between MIES scores and depression, anxiety, posttraumatic stress disorder, anger, adverse childhood experiences, and combat experiences. Across studies, internal consistency reliability was high. However, dimensionality of the MIES remained unclear, and model fit was poor across active and released Canadian Armed Forces samples. Practical and theoretical implications are discussed.
道德伤害 (MI) 被定义为在实施、未能防止或目睹违反个人道德标准或价值观的行为时所经历的深刻心理困扰。鉴于在接触军人中道德伤害经历后出现不良心理健康后果的风险增加，因此在军事人群中实施 MI 的有效和可靠措施至关重要。我们评估了常用的道德伤害事件量表 (MIES) 在两个独立的现役和退伍加拿大武装部队样本中的可靠性、聚合和区分效度，以及因素结构。在研究 1 中，MIES 分数与抑郁、焦虑、创伤后应激障碍、愤怒、不良童年经历和战斗经历之间的相关性表明了聚合和区分效度。在两个研究中，内部一致性信度均较高。然而，MIES 的维度仍不清楚，并且现役和退伍加拿大武装部队样本的模型拟合均较差。讨论了实际和理论意义。
