Abstract Purpose . No prospective studies have examined the association of poor social support and development of posttraumatic stress disorder (PTSD) in patients with chronic illness. This study addresses this knowledge gap. Design . This prospective study examines the relationship of social support to the subsequent development of PTSD during a 5-year period. Setting . San Francisco Veterans Affairs Medical Center. Subjects . A total of 579 participants with cardiovascular disease did not have PTSD at baseline and returned for the 5-year follow-up examination. Measures . PTSD measured by Computerized Diagnostic Interview Schedule for DSM-IV. Social support measured by Interpersonal Support Evaluation List (ISEL). Analysis . Unconditional ordered logistic regression analyses were performed to yield the odds ratio of developing PTSD for a one-standard-deviation change in ISEL score. Results . Of 579 participants who did not have PTSD at baseline, approximately 6.4% (n = 37) developed PTSD. Higher baseline perceived social support was strongly protective against development of PTSD (OR = .60, p = .001). Results remained significant after adjustment for age, sex, race, income, and depression (OR = .69, p = .04). Of social support types examined, the "tangible" and "belonging" domains were most strongly associated with future PTSD status. Conclusion . Social support may impact development of PTSD. Interventions that optimize social support may be part of a PTSD prevention program designed to help individuals at risk of developing PTSD.

    ABSTRACT: Objective: Despite continued outreach efforts, levels of mental health care utilization for posttraumatic stress disorder (PTSD) remain low. As such, it is important to identify factors that may promote or discourage treatment engagement. This study was designed to examine the association between perceived social support and utilization of several types of PTSD services. Methods: Data came from wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions, which was administered between 2004 and 2005. PTSD was assessed via structured interview, and perceived social support was assessed via the Interpersonal Support Evaluation List-12. Participants were asked about receipt of four modalities of PTSD-specific treatment: outpatient, hospitalization, emergency department visits, and psychiatric medication prescriptions. Weighted logistic regression modeling was performed to examine associations between social support scores and the odds of receiving treatment for PTSD, and the analyses were adjusted for sociodemographic characteristics and PTSD severity. Results: The final sample consisted of 2,811 individuals with PTSD. Social support was not associated with the odds of receiving any type of PTSD treatment. Conclusions: Among individuals in the general population with PTSD, perceived social support may not be related to PTSD treatment utilization. Other factors, such as sociodemographic characteristics and symptom severity, may be more important predictors of receipt of PTSD-specific treatment.

    ABSTRACT: A series of recent articles has reported on well-designed studies examining base rates of posttraumatic stress disorder (PTSD) screenings within the Operation Enduring Freedom (Afghanistan conflict)/Operation Iraqi Freedom (Iraq conflict) (OEF/OIF) military population. Although these studies have a number of strengths, this line of research points out several key areas in need of further examination. Many OEF/OIF Veterans do not use available Veterans Affairs (VA) services, especially mental health care. This highlights the need to understand the differences between those who use and do not use the VA, especially as research with pre-OEF/OIF Veterans suggests that these two groups differ in significant ways. The high rates of PTSD-related concerns in non-VA users also points to a need to understand whether-and where-Veterans are seeking care outside the VA and the accessibility of evidence-based, trauma-focused treatments in the community and private sectors. Careful examination of relationship status is also paramount as little research has examined relationship status or other relationship context issues. Social support, especially from a spouse, can buffer the development of PTSD; however, relationship discord has the potential to greatly exacerbate PTSD symptomatology. Furthermore, given the additional risk factors for sexual minority Veterans to be exposed to trauma, the 2011 repeal of the US Military "Don't Ask, Don't Tell" policy, and the emergence of the VA as likely the largest health care provider for sexual minority Veterans, it will be critically important to study the trauma and mental health experiences of this group. Studies that examine prevalence rates of PTSD in the returning cohort contribute significantly to our understanding of the US OEF/OIF military population. Further study of PTSD in relation to demographic variables such as VA and non-VA use, relationship status, and sexual orientation will provide rich data that will enhance our ability to develop policy and practice to provide the best care to this population.

    ABSTRACT: Low social support and small social network size have been associated with a variety of negative mental health outcomes, while their impact on mental health services use is less clear. To date, few studies have examined these associations in National Guard service members, where frequency of mental health problems is high, social support may come from military as well as other sources, and services use may be suboptimal. Surveys were administered to 1448 recently returned National Guard members. Multivariable regression models assessed the associations between social support characteristics, probable mental health conditions, and service utilization. In bivariate analyses, large social network size, high social network diversity, high perceived social support, and high military unit support were each associated with lower likelihood of having a probable mental health condition (p < .001). In adjusted analyses, high perceived social support (OR .90, CI .88-.92) and high unit support (OR .96, CI .94-.97) continued to be significantly associated with lower likelihood of mental health conditions. Two social support measures were associated with lower likelihood of receiving mental health services in bivariate analyses, but were not significant in adjusted models. General social support and military-specific support were robustly associated with reduced mental health symptoms in National Guard members. Policy makers, military leaders, and clinicians should attend to service members' level of support from both the community and their units and continue efforts to bolster these supports. Other strategies, such as focused outreach, may be needed to bring National Guard members with need into mental health care.
