Functional significance of posttraumatic growth in U.S. military Veterans

Abstract: Background: Although many studies indicate that individuals who have experienced a traumatic event can experience posttraumatic growth (PTG), some researchers have questioned the significance of PTG in associations with functioning. The role of PTG in functioning following trauma may be better elucidated by accounting for its joint effects with posttraumatic stress disorder (PTSD) symptoms. Methods: Data were analyzed from the National Health and Resilience in Veterans Study, which surveyed a nationally representative sample of 3847 trauma-exposed U.S. veterans. Participants completed assessments of potentially traumatic events, PTSD symptoms, and PTG, as well as a broad range of sociodemographic, military, trauma, health, personality, and psychosocial characteristics. Results: PTG was independently and moderately associated with higher mental, cognitive, and psychosocial functioning, but not physical functioning. Results showed a similar pattern of findings when examining relations between subdomains of PTG and these aspects of functioning. Additionally, among veterans who screened positive for PTSD, those who endorsed PTG reported higher levels of mental, cognitive, and/or psychosocial functioning than those who did not endorse PTG. Limitations: Findings may be limited by the use of a cross-sectional design, retrospective self-reports of PTG, and a predominantly older white male veteran sample. Conclusion: Results provide support for the functional significance of PTG and highlight the importance of considering PTSD symptoms to better understand the role of PTG in functioning. Clinical interventions to foster PTG may help promote post-trauma functioning.

    Qualitative analysis of the lived experience of reproductive and pediatric health care in the military health care system

    Abstract: Introduction: Persistent inequities exist in obstetric and neonatal outcomes in military families despite universal health care coverage. Though the exact underlying cause has not been identified, social determinants of health may uniquely impact military families. The purpose of this study was to qualitatively investigate the potential impact of social determinants of health and the lived experiences of military individuals seeking maternity care in the Military Health System. Materials and methods: This was an Institutional Review Board-approved protocol. Nine providers conducted 31 semi-structured interviews with individuals who delivered within the last 5 years in the direct or purchased care market. Participants were recruited through social media blasts and clinic flyers with both maximum variation and homogenous sampling to ensure participation of diverse individuals. Data were coded and themes were identified using inductive qualitative research methods. Results: Three main themes were identified: Requirements of Military Life (with subthemes of pregnancy notification and privacy during care, role of pregnancy instructions and policies, and role of command support), Sociocultural Aspects of the Military Experience (with subthemes of pregnancy as a burden on colleagues and a career detractor, postpartum adjustment, balancing personal and professional requirements, pregnancy timing and parenting challenges, and importance of friendship and camaraderie in pregnancy), and Navigating the Healthcare Experience (including subthemes of transfer between military and civilian care and TRICARE challenges, perception of military care as inferior to civilian, and remote duty stations and international care). Conclusions: The unique stressors of military life act synergistically with the existing health care challenges, presenting opportunities for improvements in care. Such opportunities may include increased consistency of policies across services and commands. Increased access to group prenatal care and support groups, and increased assistance with navigating the health care system to improve care transitions were frequently requested changes by participants.
