Homelessness among US veterans has been a focus of research for over 3 decades. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, this is the first systematic review to summarize research on risk factors for homelessness among US veterans and to evaluate the evidence for these risk factors. Thirty-one studies published from 1987 to 2014 were divided into 3 categories: more rigorous studies, less rigorous studies, and studies comparing homeless veterans with homeless nonveterans. The strongest and most consistent risk factors were substance use disorders and mental illness, followed by low income and other income-related factors. There was some evidence that social isolation, adverse childhood experiences, and past incarceration were also important risk factors. Veterans, especially those who served since the advent of the all-volunteer force, were at greater risk for homelessness than other adults. Homeless veterans were generally older, better educated, and more likely to be male, married/have been married, and to have health insurance coverage than other homeless adults. More studies simultaneously addressing premilitary, military, and postmilitary risk factors for veteran homelessness are needed. This review identifies substance use disorders, mental illness, and low income as targets for policies and programs in efforts to end homelessness among veterans.

Background: There is increasing recognition that, in addition to negative psychological consequences of trauma such as post-traumatic stress disorder (PTSD), some individuals may develop post-traumatic growth (PTG) following such experiences. To date, however, data regarding the prevalence, correlates and functional significance of PTG in population-based samples are lacking.Method: Data were analysed from the National Health and Resilience in Veterans Study, a contemporary, nationally representative survey of 3157 US veterans. Veterans completed a survey containing measures of sociodemographic, military, health and psychosocial characteristics, and the Posttraumatic Growth Inventory-Short Form.Results: We found that 50.1% of all veterans and 72.0% of veterans who screened positive for PTSD reported at least ‘moderate’ PTG in relation to their worst traumatic event. An inverted U-shaped relationship was found to best explain the relationship between PTSD symptoms and PTG. Among veterans with PTSD, those with PTSD reported better mental functioning and general health than those without PTG. Experiencing a life-threatening illness or injury and re-experiencing symptoms were most strongly associated with PTG. In multivariable analysis, greater social connectedness, intrinsic religiosity and purpose in life were independently associated with greater PTG.Conclusions: PTG is prevalent among US veterans, particularly among those who screen positive for PTSD. These results suggest that there may be a ‘positive legacy’ of trauma that has functional significance for veterans. They further suggest that interventions geared toward helping trauma-exposed US veterans process their re-experiencing symptoms, and to develop greater social connections, sense of purpose and intrinsic religiosity may help promote PTG in this population.

To evaluate the prevalence of DSM-5 posttraumatic stress disorder (PTSD) and factor structure of PTSD symptomatology in a nationally representative sample of US veterans and examine how PTSD symptom clusters are related to depression, anxiety, suicidal ideation, hostility, physical and mental health-related functioning, and quality of life. Data were analyzed from the National Health and Resilience in Veterans Study, a nationally representative survey of 1,484 US veterans conducted from September through October 2013. Confirmatory factor analyses were conducted to evaluate the factor structure of PTSD symptoms, and structural equation models were constructed to examine the association between PTSD symptom clusters and external correlates. 12.0% of veterans screened positive for lifetime PTSD and 5.2% for past-month PTSD. A 5-factor dysphoric arousal model and a newly proposed 6-factor model both fit the data significantly better than the 4-factor model of DSM-5. The 6-factor model fit the data best in the full sample, as well as in subsamples of female veterans and veterans with lifetime PTSD. The emotional numbing symptom cluster was more strongly related to depression (P < .001) and worse mental health-related functioning (P < .001) than other symptom clusters, while the externalizing behavior symptom cluster was more strongly related to hostility (P < .001). A total of 5.2% of US veterans screened positive for past-month DSM-5 PTSD. A 6-factor model of DSM-5 PTSD symptoms, which builds on extant models and includes a sixth externalizing behavior factor, provides the best dimensional representation of DSM-5 PTSD symptom clusters and demonstrates validity in assessing health outcomes of interest in this population.

Background There are significant concerns about mental health problems occurring due to the coronavirus disease 2019 (COVID‐19) pandemic. To date, there has been limited empirical investigation about thoughts of suicide and self‐harm during the COVID‐19 pandemic. Methods A national survey was conducted May 2020 to investigate the association between mental health symptoms, social isolation, and financial stressors during the COVID‐19 pandemic and thoughts of suicide and self‐harm. A total of 6607 US adults completed an online survey; survey criteria included an age minimum of 22 years old and reported annual gross income of $75,000 or below. Statistical raking procedures were conducted to more precisely weight the sample using US Census data on age, geographic region, sex, race, and ethnicity. Results COVID‐19‐related stress symptoms, loneliness, and financial strain were associated with thoughts of suicide/self‐harm in multivariable logistic regression analyses, as were younger age, being a military veteran, past homelessness, lifetime severe mental illness, current depressive symptoms, alcohol misuse, and having tested positive for COVID‐19. Greater social support was inversely related to thoughts of suicide/self‐harm whereas running out of money for basic needs (e.g., food), housing instability (e.g., delaying rent), and filing for unemployment or disability were positively related. Conclusions Public health interventions to decrease risk of suicide and self‐harm in the wake of the COVID‐19 pandemic should address pandemic‐related stress, social isolation, and financial strain experienced including food insecurity, job loss, and risk of eviction/homelessness.
