Posttraumatic Mental Contamination and the Interpersonal Psychological Theory of Suicide: Effects via DSM-5 PTSD Symptom Clusters

AbstractResearch has yet to establish a relationship between posttraumatic mental contamination and suicide risk, despite theoretical overlap. The present study examined relationships between posttraumatic mental contamination and suicide risk via posttraumatic stress symptom clusters and appraisals of perceived burdensomeness and thwarted belongingness. Trauma-exposed participants (N = 183) completed measures of posttraumatic mental contamination, posttraumatic stress symptoms, thwarted belongingness, perceived burdensomeness, and suicide risk. Findings revealed significant indirect effects of posttraumatic mental contamination on suicide risk via all posttraumatic stress s ymptom clusters. Significant serial indirect effects of posttraumatic mental contamination on suicide risk were observed via posttraumatic avoidance and arousal/reactivity and, subsequently, via thwarted belongingness and perceived burdensomeness. Serial models via posttraumatic re-experiencing and negative cognitions/mood symptoms were nonsignificant. Results suggest that posttraumatic mental contamination may increase suicide risk via posttraumatic stress symptom severity, and maladaptive interpersonal appraisals may explain these links through distinct symptom pathways. Implications for pos ttraumatic suicide risk are discussed.

As the COVID-19 pandemic and its economic effects spread, concerns about mental health impacts continue to grow. For example, we worry for health and human services professionals whose duties involve higher risk for trauma exposure and post-traumatic stress. Reports of global increases in family violence also suggest that there will be many violence victims and witnesses in need of mental health support. Add to this the potential effects of social isolation, health-related anxiety, and that these mental health problems may persist and worsen long after society goes back to “normal.” And this is all happening as...

ConclusionsYounger participants had greater symptom improvement, particularly if they received individual treatment. Other pretreatment variables did not predict outcome. CPT appears to be robust across most pretreatment variables, such that comorbid disorders, baseline symptom severity, and suicidal ideation do not interfere with application of CPT. However, individual CPT may be a better option particularly for younger service members.

AbstractPurpose of ReviewPost-traumatic nightmares (PTN) are a common and enduring problem for individuals with post-traumatic stress disorder (PTSD) and other clinical presentations. PTN cause significant distress, are associated with large costs, and are an independent risk factor for suicide. Pharmacological and non-pharmacological treatment options for PTN exist. A previous review in this journal demonstrated that Prazosin, an alpha blocker, was a preferred pharmacological treatment for PTN and imagery rescripting therapy (IRT) was a preferred non-pharmacological treatment. Since that time, new and important research f...

AbstractWith approximately 20 veteran suicide deaths per day, suicidal ideation (SI) among veterans is an important concern. Posttraumatic stress disorder (PTSD) is associated with SI among veterans, yet mechanisms of this relationship remain unclear. Negative posttraumatic cognitions contribute to the development and maintenance of PTSD, yet no studies have prospectively examined the relationship between posttraumatic cognitions and SI. Veterans (N = 177; 66% Male) participating in a 3-week intensive outpatient program for PTSD completed assessments of PTSD severity, depressive symptoms, SI, and posttraumati...

DiscussionCBT for anxiety disorders was associated with significant reductions in SI over time, with no evidence for exacerbation of suicide risk. Clinical implications are discussed, as well as future research directions to further understand the effect of anxiety disorder treatments on SI.

Suicide remains a significant public health problem for the United States military. Trauma-related diagnoses such as acute stress disorder (ASD) or posttraumatic stress disorder (PTSD) may exacerbate suicide risk, particularly among service members psychiatrically hospitalized following suicide-related events. To date, treatments to address suicide risk and trauma symptomatology among service members within inpatient milieus have been nonexistent. To address this gap, a randomized controlled pilot trial of Post-Admission Cognitive Therapy (PACT) was conducted to evaluate a targeted cognitive-behavioral program among trauma...
