Background: Exposure to adversity in utero is thought to increase susceptibility to develop posttraumatic stress disorder (PTSD) following later life trauma, due to neurobiological programming effects during critical developmental periods. It remains unknown whether effects of prenatal adversity on PTSD susceptibility are modulated by genetic variations in neurobiological pathways implicated in PTSD susceptibility.

Background: Potentially morally injurious experiences (PMIEs) are common during military service. However, it is unclear to what extent PMIEs are related to well-established adverse mental health outcomes.

Objective: The objective of this study was to use a population-based survey to determine the associations between moral injury endorsement and the presence of past-year mental health disorders in Canadian Armed Forces (CAF) personnel and Veterans.

There is growing evidence that parental trauma is associated with psychosocial disorders, externalizing and internalizing problems, and higher sensitivity to posttraumatic stress disorder (PTSD) in children. Recent research findings suggest multidimensional relational, psychological, and neurobiological interrelated pathways of intergenerational influence. Moreover, the intergenerational effects of parental trauma need to be understood within a broader systemic context, as a part of family adaptation.

This study seeks to understand a dynamic model of moral injury: traumatic experience caused by behavior that contradicts the moral principles individual holds. Although past studies mostly focused on specific group, this article considers more general context, while exploring the process of re-evaluating an individual's existing values.
