Shame Mediates Emotion Dysregulation and PTSD Symptoms in Combat Veterans

Posttraumatic stress disorder (PTSD) is one of the most prevalent mental health disorders among US veterans (Magruder et al., 2005) and is associated with emotion dysregulation (i.e., an inability to effectively respond to emotional experiences; Gratz & Roemer, 2004). For example, emotion dysregulation has been identified as a developmental predictor of chronic PTSD (Pencea et al., 2020). Additionally, improvements in emotion dysregulation have corresponded with reductions in PTSD symptoms (Price et al., 2006) and emotion dysregulation has mediated reductions in PTSD severity over the course of Prolonged Exposure (PE; McLean et al., 2019). However, it is unclear if specific emotions play a role in this relationship. 

Shame, a negative evaluative emotion about oneself, is commonly associated with the development, maintenance (López-Castro et al., 2019), and severity (Cunningham et al., 2018) of PTSD, as well as positively associated with emotion dysregulation (Paulus et al., 2016). Shame may be particularly problematic for combat veterans suffering from PTSD. Moral injury, or the psychological suffering that follows actions, inaction, or events that transgress deeply held moral beliefs, is commonly observed in combat veterans and situates shame as one of the primary mechanisms of moral injury development (Frankfurt & Frazier, 2016). 

Notably, shame may be critical in determining the effect of emotion dysregulation on PTSD symptoms in this population. Specifically, previous research found that emotion dysregulation had no influence on PTSD severity among combat veterans with high levels of shame upon entering treatment (Puhalla et al., 2021). Moreover, emotional awareness (a component of emotion regulation) predicted lower PTSD severity for veterans with low levels of shame, but greater PTSD severity for veterans with high levels of shame. This finding suggests that shame may play an important role within the relationship between emotion dysregulation and PTSD. 
Our study examined how changes in shame and emotion dysregulation affected PTSD symptom improvement among combat veterans and whether shame acted as a mediator between changes in emotion dysregulation and PTSD symptoms in response to residential treatment. Within the residential program, veterans engaged in individual and group therapy, with 74% agreeing to an EBP for PTSD (e.g., Cognitive Processing Therapy [CPT; Resick et al., 2016] or PE; Foa et al., 2019).

Using self-report data from 43 male combat veterans who completed the residential program, we found that reductions in emotion dysregulation and shame were associated with reductions in PTSD symptoms over the course of treatment. Additionally, we found that shame significantly mediated the relationship between emotion dysregulation and PTSD symptoms.

Teaching emotion regulation techniques can be a highly effective skill for many psychiatric disorders. However, our data suggests that for combat veterans receiving an EBP in residential treatment for PTSD, these improvements are partially explained by reducing shame. This reduction of shame may occur several ways. For example, in CPT, shame may be addressed through the processing of the trauma and through Socratic dialogue which can assist in challenging shameful beliefs. Further, it is possible that as shame decreases, individuals can minimize the use of maladaptive coping strategies (e.g., emotional avoidance, substance use). This may be conducted through PE and group programing, as it encourages approach over avoidance. Finally, adaptive, skills-based strategies (i.e., DBT skills) may only be effective in reducing PTSD symptoms if shame is targeted and reduced among this population, as combat veterans may continue to utilize maladaptive strategies over adaptive ones if they have strong negative beliefs about themselves (e.g., “I am a monster, I am broken”) and potentially feel they do not deserve to get better (e.g., “I deserve this for who I am and what I did”). 

Altogether, our findings show the importance of reducing shame to alleviate PTSD symptoms. Importantly, evidence-based treatment in the context of residential programming may provide a framework for combat veterans to address shame through exposure, cognitive restructuring, and normalization through interacting with peers.

Discussion Questions

  1. What residential treatment factors may have contributed to the study findings?
  2. Why may addressing shame be especially important for combat veterans with PTSD?
  3. How may these findings have differed with other PTSD samples with different characteristics (e.g., female, non-combat veterans, community PTSD)?
