Relationships between resilience, perceived social support, and mental health in military personnel: A cross-lagged analysis

Abstract: Background: Despite the growing application of the Dual-factor model of mental health (DFM), there is a paucity of research on military personnel. Additionally, existing cross-sectional studies indicate that resilience and perceived social support are associated with military mental health, but the lack of cross-lagged studies precludes researchers from making causal interpretations. This study aimed to explore the longitudinal relationship between resilience, perceived social support, negative dimension of mental health (depressive symptom), and positive dimension (life satisfaction) among military personnel using cross-lagged analysis. Methods: A total of 215 military personnel were investigated longitudinally over a 12-week, two-phase period. The Connor-Davidson Resilience Scale (CD-RISC), Perceived Social Support Scale (PSSS), Patients' Health Questionnaire Depression Scale-9 Item (PHQ-9), and Satisfaction with Life Scale (SWLS) were employed to measure their resilience, perceived social support, depression symptoms, and life satisfaction, respectively. Pearson correlation analysis was used to examine the correlations between the aforementioned variables, and a paired t-test was employed to ascertain whether the variables changed over time. A cross-lagged panel analysis was employed to explore cross-lagged relationships between these variables in military personnel. Results: All participants in this study were male. At Time 1, the mean age of all participants was 22.98 years (SD = 2.99), and the mean scores for the CD-RISC, PSSS, PHQ-9, and SWLS were 71.61 (SD = 14.86), 68.60 (SD = 10.22), 1.74 (SD = 2.89), and 28.08 (SD = 5.51), respectively. Cross-lagged analysis showed that prior resilience significantly predicted later depression symptoms (β = -0.19, p = 0.028) and life satisfaction (β = 0.17, p = 0.038). Prior perceived social support significantly predicted later life satisfaction (β = 0.15, p = 0.040) but not depression symptoms (β = -0.04, p = 0.652). Prior depression symptoms significantly predicted later life satisfaction (β = -0.26, p < 0.001), and prior life satisfaction also predicted later depression symptoms (β = -0.23, p = 0.002). Conclusions: The negative and positive dimensions of military mental health can interact with each other. Moreover, enhancing resilience and perceived social support may be a novel perspective for improving the mental health of military personnel.

    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.
