Randomized Clinical Trial of Brief Primary Care-Based Mindfulness Training Versus a Psychoeducational Group for Veterans With Posttraumatic Stress Disorder.

Objective: Individuals with posttraumatic stress disorder (PTSD) symptoms are often reluctant to engage in traditional mental health care but do seek primary care services. Alternative strategies are needed to develop emotional regulation skills among individuals with PTSD symptoms. This study examined the feasibility and effectiveness of Primary Care Brief Mindfulness Training (PCBMT) compared to a psychoeducational group for reducing PTSD symptoms.Methods: Primary care patients (n = 55) with DSM-5 PTSD symptoms but not engaged in PTSD psychotherapies were randomized to 4-week PCBMT or a PTSD psychoeducation group (EDU). Both groups were cofacilitated by mental health providers and veteran peer specialists. Between January 2019 and March 2020, assessments were completed at baseline, post-treatment, and 16- and 24-week follow-up.Results: PCBMT participants had significantly larger decreases in PTSD symptoms from pre- to post-treatment (d = 0.57) and depression from pre-treatment to 16- and 24-week follow-ups (d = 0.67, 0.60) compared to EDU. PCBMT participants also reported significantly greater improvements in health responsibility (d = 0.79), stress management (d = 0.99), and not feeling dominated by symptoms (d = 0.71). Both interventions resulted in the majority of participants "stepping up" to a higher level of PTSD care.Conclusions: Brief mindfulness training is effective for reducing psychiatric symptoms and improving broader recovery outcomes and health promoting behaviors. For individuals who are not yet willing to engage in trauma-focused PTSD treatment, PCBMT may be preferable and more effective than psychoeducational classes as preliminary treatments. Further research is needed to confirm the effectiveness of PCBMT in a larger sample and investigate factors that will support wider implementation in primary care settings.Clinical Trials Registration: ClinicalTrials.gov identifier: NCT03352011.

Ecological momentary assessment of PTSD symptoms and alcohol use in combat veterans.

Despite high rates of comorbid hazardous alcohol use and posttraumatic stress disorder (PTSD), the nature of the functional relationship between these problems is not fully understood. Insufficient evidence exists to fully support models commonly used to explain the relationship between hazardous alcohol use and PTSD including the self-medication hypothesis and the mutual maintenance model. Ecological momentary assessment (EMA) can monitor within-day fluctuations of symptoms and drinking to provide novel information regarding potential functional relationships and symptom interactions. This study aimed to model the daily course of alcohol use and PTSD symptoms and to test theory-based moderators, including avoidance coping and self-efficacy to resist drinking. A total of 143 recent combat veterans with PTSD symptoms and hazardous drinking completed brief assessments of alcohol use, PTSD symptoms, mood, coping, and self-efficacy 4 times daily for 28 days. Our results support the finding that increases in PTSD are associated with more drinking within the same 3-hr time block, but not more drinking within the following time block. Support for moderators was found: Avoidance coping strengthened the relationship between PTSD and later drinking, while self-efficacy to resist drinking weakened the relationship between PTSD and later drinking. An exploratory analysis revealed support for self-medication occurring in certain times of the day: Increased PTSD severity in the evening predicted more drinking overnight. Overall, our results provide mixed support for the self-medication hypothesis. Also, interventions that seek to reduce avoidance coping and increase patient self-efficacy may help veterans with PTSD decrease drinking.

The Relationship Between Post-Deployment Factors and PTSD Severity in Recent Combat Veterans.

Combat traumas precipitate PTSD, however non-traumatic deployment and post-deployment factors may also contribute to PTSD severity. The Deployment Risk and Resilience Inventory was used to investigate pre, peri and post-deployment factors associated with current PTSD severity in 150 recent combat veterans with PTSD and hazardous alcohol use. Hierarchal linear regression analyzed what factors independently predicted PTSD severity when controlling for socio-demographic characteristics and combat specific variables. Four post-deployment factors independently predicted PTSD severity: unemployment, alcohol use, social support, stressful (non-traumatic) life events. The centrality of trauma in the maintenance of PTSD and clinical implications for treatment providers are discussed.
