Deployment-Related Benefit Finding and Postdeployment Marital Satisfaction in Military Couples

PTSD service dogs foster resilience among veterans and military families

Military deployment and reintegration challenges permeate the lives and relationships of Veterans, their spouses, and their families. Among these challenges, 23% of post-9/11 Veterans have been diagnosed with posttraumatic stress disorder (PTSD). Psychiatric service dogs have been found to help clinically alleviate PTSD symptoms when used as a complementary intervention. However, minimal research exists that explores the role of the service dog as a mechanism for cultivating resilience within the military family system. Researchers utilized a qualitative, constant comparative approach to analyze self-reported experiences of 101 individuals, including Veterans (n = 67) and their spouses (n = 34). Analyzed through the framework of the Theory of Resilience and Relational Load (Afifi et al., 2016), findings suggest complex communication processes that facilitate relational and family adaptation. These processes encompassed (a) the role of the service dog in building emotional reserves, (b) relational load introduced when caring for the service dog, and (c) the service dog's facilitation of relational maintenance behaviors among family members that contributed to communal orientation. Based on the results of this qualitative analysis, researchers suggest educational interventions where service dog trainers and mental health practitioners can incorporate relational maintenance strategies and family-focused approaches to integrating service dogs as military family members.

Reversal of Stress-Induced Social Interaction Deficits by Buprenorphine

BACKGROUND

Patients with post-traumatic stress disorder frequently report persistent problems with social interactions, emerging after a traumatic experience. Chronic social defeat stress is a widely used rodent model of stress that produces robust and sustained social avoidance behavior. The avoidance of other rodents can be reversed by 28 days of treatment with selective serotonin reuptake inhibitors, the only pharmaceutical class approved by the U.S. Food and Drug Administration for treating post-traumatic stress disorder. In this study, the sensitivity of social interaction deficits evoked by 10 days of chronic social defeat stress to prospective treatments for post-traumatic stress disorder was examined.

METHODS

The effects of acute and repeated treatment with a low dose of buprenorphine (0.25 mg/kg/d) on social interaction deficits in male C57BL/6 mice by chronic social defeat stress were studied. Another cohort of mice was used to determine the effects of the selective serotonin reuptake inhibitor fluoxetine (10 mg/kg/d), the NMDA antagonist ketamine (10 mg/kg/d), and the selective kappa opioid receptor antagonist CERC-501 (1 mg/kg/d). Changes in mRNA expression of Oprm1 and Oprk1 were assessed in a separate cohort.

RESULTS

Buprenorphine significantly reversed social interaction deficits produced by chronic social defeat stress following 7 days of administration, but not after acute injection. Treatment with fluoxetine for 7 days, but not 24 hours, also reinstated social interaction behavior in mice that were susceptible to chronic social defeat. In contrast, CERC-501 and ketamine failed to reverse social avoidance. Gene expression analysis found: (1) Oprm1 mRNA expression was reduced in the hippocampus and increased in the frontal cortex of susceptible mice and (2) Oprk1 mRNA expression was reduced in the amygdala and increased in the frontal cortex of susceptible mice compared to non-stressed controls and stress-resilient mice.

CONCLUSIONS

Short-term treatment with buprenorphine and fluoxetine normalized social interaction after chronic social defeat stress. In concert with the changes in opioid receptor expression produced by chronic social defeat stress, we speculate that buprenorphine's efficacy in this model of post-traumatic stress disorder may be associated with the ability of this compound to engage multiple opioid receptors.

Integrative Intensive Retreats for Veteran Couples and Families: A Pilot Study Assessing Change in Relationship Adjustment, Posttraumatic Growth, and Trauma Symptoms

We assessed a brief, systemic retreat-style intervention that was developed to address concerns about the utilization of services for veterans coping with traumatic stress. A total of 76 dyads (N = 152) were assessed before and after a 4-day retreat, which included psychoeducation, group and conjoint therapeutic sessions, and recreational relaxation components. Overall, participants reported a reduction in trauma symptoms, but only support persons experienced a significant increase in posttraumatic growth from pretest to posttest. Both veterans and their romantic partners reported an increase in relationship adjustment after the retreat. Opportunities to address the needs of this population by removing barriers to treatment and reducing feelings of isolation, as well as implications for similar treatments are discussed.
