Changes in guilt cognitions in intensive PTSD treatment among veterans who experienced military sexual trauma or combat trauma

Changes in guilt cognitions mediate the effect of trauma-informed guilt reduction therapy on PTSD and depression outcomes

OBJECTIVE

Trauma-informed guilt reduction therapy (TrIGR), a six-session cognitive behavioral therapy targeting trauma-related guilt and distress, reduces guilt and symptoms of posttraumatic stress disorder (PTSD) and depression, yet little is known regarding how and why TrIGR may be effective.

METHOD

This study examined treatment-related changes in avoidant coping and trauma-related guilt cognitions as possible mediators of treatment effects on PTSD and depression outcomes at 3- and 6-month follow-up. Data were from a randomized controlled trial for treatment of trauma-related guilt comparing TrIGR and supportive care therapy among 145 post-9/11 US veterans (Mage = 39.2 [8.1], 93.8% male).

RESULTS

At pretreatment, most (86%) met PTSD criteria. Intent to treat analyses using parallel mediation models indicated changes in guilt cognitions, but not avoidant coping, mediated the effect of TrIGR on reducing PTSD severity at 3-month (a × b = -0.15, p < 0.01, 95% CI: [-0.24 to -0.06], p = 0.001) and 6-month (a × b = -0.17, 95% CI: [-0.26 to -0.07], p = 0.001) follow-up. Similarly, changes in guilt cognitions, but not avoidant coping, mediated the effect of TrIGR on reducing depression severity at 3-month (a × b = -0.10, 95% CI: [-0.18 to -0.02], p = 0.02) and 6-month (a × b = -0.11, 95% CI: [-0.20 to -0.03], p = 0.01) follow-up.

CONCLUSIONS

Compared to guilt cognitions, changes in avoidant coping were less integral to downstream PTSD and depression symptom reduction. Guilt cognition change may be a salient active ingredient of PTSD and depression treatment for those with trauma-related guilt and a key therapy element to which providers should be attuned.

Health and psychiatric impairment associated with moral injury, military sexual trauma, and their co-occurrence in U.S. combat veterans

BACKGROUND

Military sexual trauma (MST) and moral injury (MI) are associated with adverse psychiatric and health outcomes among military veterans. However, no known population-based studies have examined the incremental burden associated with the co-occurrence of these experiences relative to either alone.

METHOD

Cross-sectional data were analyzed from the National Health and Resilience in Veterans Study, a nationally representative sample of 1330 U.S. combat veterans. Veterans reported on history of exposure to MST and potentially morally injurious events (PMIEs). Analyses estimated the lifetime prevalence of MST only, PMIEs only, and co-occurring MST and PMIEs; and examined associations between MST/PMIEs status and psychiatric and physical health comorbidities, functioning, and suicidality.

RESULTS

The lifetime weighted prevalence of exposure to MST only, PMIEs only, and co-occurring MST and PMIEs were 2.7%, 32.3%, and 4.5%, respectively. Compared with all other groups, the co-occurring MST + PMIEs group reported greater severity of posttraumatic stress, depression, generalized anxiety, and insomnia symptoms. They also scored lower on measures of physical, mental, and psychosocial functioning, and reported a greater number of chronic medical conditions and somatic complaints. Veterans with co-occurring MST + PMIEs were more than twice as likely as those with MST only to report past-year suicidal ideation.

CONCLUSIONS

The co-occurrence of MST and MI is associated with a greater psychiatric and health burden among combat veterans than either experience alone. Results underscore the importance of assessing and treating MST and MI in this population. Findings underscore the importance for future work to parse overlap between morally salient aspects of MST and the concept of moral injury.

Patterns of social-affective responses to trauma exposure and their relation to psychopathology

INTRODUCTION

Traumatic event exposure is a risk factor for the development and maintenance of psychopathology. Social-affective responses to trauma exposure (e.g. shame, guilt, revenge, social alienation) could moderate this relationship, but little is known about their relevance for different types of psychopathology. Moreover, the interplay of different social-affective responses to trauma exposure in predicting psychopathology is poorly understood.

METHODS

In a sample of N = 1321 trauma-exposed German soldiers, we examined cross-sectional associations of trauma-related social alienation, revenge, guilt and shame with depressive disorder, alcohol use disorder, posttraumatic stress disorder and dimensional measures of depression and anxiety. Latent class analysis was conducted to identify possible patterns of social-affective responses to trauma exposure, and their relation to psychopathology.

RESULTS

All social-affective responses to trauma exposure predicted current posttraumatic stress disorder, depressive disorder, alcohol use disorder and higher depressive and anxiety symptoms. Three latent classes fitted the data best, reflecting groups with (1) low, (2) moderate and (3) high risk for social-affective responses to trauma exposure. The low-risk group demonstrated the lowest expressions on all psychopathology measures.

CONCLUSIONS

Trauma-related social alienation, shame, guilt, and revenge are characteristic of individuals with posttraumatic stress disorder, depressive disorder, alcohol use disorder, and with higher anxiety and depressive symptoms. There was little evidence for distinctive patterns of social-affective responses to trauma exposure despite variation in the overall proneness to show social-affective responses. Social-affective responses to trauma exposure could represent promising treatment targets for both cognitive and emotion-focused interventions.
