Treatment for Moral Injury: Impact of Killing in War

Purpose of Review Veterans who kill in war are at risk of developing negative mental health problems including moral injury, PTSD, spiritual distress, and impairments in functioning. Impact of Killing (IOK) is a novel, cognitive-behaviorally based treatment designed to address the symptoms associated with killing that focuses on self-forgiveness and moral repair through cultivation of self-compassion and perspective-taking exercises, such as letter writing, and active participation in values-driven behavior. Recent Findings In a pilot trial assessing IOK, participants demonstrated a reduction in multiple mental health symptoms and improvement in quality-of-life measures, and they reported IOK was acceptable and feasible. Furthermore, trauma therapists have reported that moral injury is relevant to their clinical work, expressed a desire for additional training on the impact of killing, and identified barriers that make addressing killing in clinical settings challenging. Data are currently being collected in a national multi-site trial to examine the efficacy of IOK, compared to a control condition. Summary IOK fills a critical treatment gap by directly addressing the guilt, shame, self-sabotaging behaviors, functional difficulties, impaired self-forgiveness, and moral/spiritual distress directly associated with killing in war. Typically provided following some initial trauma-processing treatment, IOK can be integrated in existing systems of trauma care, creating a pathway for a stepped model of treatment for moral injury.
