The impact of social support and morally injurious events on PTSD symptoms in Veterans.

Potentially morally injurious events (PMIEs), including committing transgressions (Transgressions-Self) and perceiving betrayals, have been positively associated with posttraumatic stress disorder (PTSD). A proposed mechanism for the association between PMIEs and PTSD symptoms is social disconnection. However, research on PMIEs and social disconnection is limited. Secondary data analysis from a larger study examined the moderating role of different sources of perceived social support (Family, Friends, and Significant Other) on the relation between PMIEs (Transgressions-Self and Betrayal) and PTSD. The interaction of Transgressions-Self and perceived social support subscales did not predict PTSD symptoms. However, the interaction of Betrayals and perceived social support (Significant Other and Family) predicted PTSD symptoms. Results suggest that perceived social support provides a protective effect for low to mean levels of perceived betrayals; however, for Veterans reporting high levels of betrayal, perceived social support did not attenuate PTSD symptom severity. Additional research on perceived betrayals and the association with PTSD is needed, especially for Veterans who experience high levels of perceived betrayals.
