Moral Injury: An Integrative Review

Area of Science:

• Psychology
• Trauma Studies
• Mental Health Research

Background:

• Moral injury is a significant issue affecting individuals exposed to events that violate their moral values.
• It leads to severe distress and functional impairments, gaining attention from various sectors including mental health and the public.
• Research on moral injury, particularly in military personnel and veterans, has increased substantially over the past decade.

Purpose of the Study:

• To review and synthesize existing scientific research on moral injury.
• To identify the biological, psychological, social, and spiritual consequences of potentially morally injurious events.
• To examine current understanding and treatment approaches for moral injury, including challenges and future directions.

Main Methods:

• A comprehensive review of scientific literature was conducted.
• 116 relevant epidemiological and clinical studies on moral injury were identified and analyzed.
• The review synthesized findings on sequelae and discussed treatment models and limitations.

Main Results:

• Epidemiological studies reveal diverse sequelae (biological, psychological, social, spiritual) from potentially morally injurious events.
• Clinical literature shows debate on moral injury's response to PTSD treatments and emerging models for moral repair.
• Identified limitations include variable definitions, lack of consensus measures, and limited research outside military contexts.

Conclusions:

• The scientific literature on moral injury highlights its wide-ranging impacts but also significant gaps.
• Further research is needed to establish clear definitions, standardized measures, and effective, evidence-based treatments for moral injury.
• Future studies should explore moral injury in diverse populations and clarify therapeutic mechanisms for moral repair.
