A score of 27 or greater on the Moral Injury and Distress Scale (MIDS) identifies clinically meaningful and impairing moral injury

Background on Moral Injury

Moral injury is the emotional pain and functional impairment people can experience after participating in, failing to prevent, or witnessing highly stressful events that transgress their beliefs about right and wrong. In recent years, there has been an explosion of interest in moral injury and its impacts. We now know that exposure to potentially morally injurious events is common among many groups at high risk for trauma (e.g., veterans, healthcare professionals, first responders) and that moral injury is associated with greater risk of functional impairment, posttraumatic stress, depression, suicidal thoughts and behaviors, and problematic substance use.

The Moral Injury and Distress Scale (MIDS)

It is important for mental health professionals to know how to identify people with moral injury and to be able to assess if novel and existing interventions targeting moral injury and related problems are helpful to them. Yet, until recently, we have not had the tools to do so. The Moral Injury and Distress Scale (MIDS) was developed to address these gaps. The first study of the MIDS showed that it has strong psychometric properties to measure exposure to potentially morally injurious events and related moral injury symptoms in three high-risk populations. This new study just published in the Journal of Traumatic Stress shows that the MIDS can be used to identify those with clinically meaningful and impairing moral injury. The authors examined data from 645 military veterans, healthcare workers, and first responders who endorsed exposure to potentially morally injurious events. Using signal detection methods, the authors identified the optimally efficient MIDS score for detecting clinically significant posttraumatic stress and depression symptom severity, trauma-related guilt, and functional impairment. A cut score of 27 was recommended because roughly 70% of participants screening positive on the MIDS at this threshold reported clinically significant mental health symptoms and 50% reported severe trauma-related guilt and/or functional impairment.

Implications of Study

This is the first study to use data-driven methods that establish a cut score for clinically meaningful and impairing moral injury. Having this cut score can help clinicians to conduct measurement-based moral injury care, identify individuals at risk of negative outcomes because of moral injury, and to better understand risk and protective factors for moral injury. The MIDS can be downloaded at this link.

Discussion Questions

1. How will having a method to identify clinically meaningful and impairing moral injury help move the field of moral injury forward?
2. How can the MIDS cut score be used in clinical practice and/or research?
3. What are the potential advantages and disadvantages of adding moral injury to the diagnostic classification systems typically used by mental health professionals (e.g., Diagnostic and Statistical Manual-5-Text Revision)
