Clinical Trial Summary
Posttraumatic stress disorder (PTSD) is a common and impairing problem among Veterans, many
of whom first seek treatment in primary care settings. PTSD is linked to reduced quality of
life and increased rates of suicide. Additionally, social support, defined as the
availability of others to provide emotional or practical support when needed, is frequently
poor for Veterans with PTSD. For Veterans with PTSD, poor social support negatively impacts
PTSD treatment engagement and outcomes, interfering with PTSD recovery. There is a need for
additional brief, primary care-based treatments for PTSD that also work to improve social
support in traumatized Veterans. The proposed research seeks to evaluate and refine such an
intervention and establish a protocol for routinely measuring social support to inform
treatment. This intervention and measurement protocol will likely improve Veterans' mental
health and social relationships.
Description:
Background: PTSD is a significant problem for Veterans, most of whom are initially treated
for posttraumatic stress disorder (PTSD) in Primary Care Mental Health Integration (PCMHI).
Poor social support in this population is a risk factor for suicidal ideation, all-cause
mortality, and worse treatment engagement and response. Preliminary research shows that
approximately 60% of Veterans with PTSD present to specialty care intake appointments with
poor social support. However, none of the existing PCMHI-based treatments for PTSD explicitly
focus on social support generation or reengagement. Moreover, although the limited existing
research suggests that the routine assessment of social support to guide treatment planning
(also known as measurement-based care, or MBC) improves treatment outcomes in civilian
populations, social support is not routinely monitored as part of evidence-based treatments
for PTSD. Thus, this CDA-2 will first identify an appropriate instrument for routinely
measuring social support in the context of clinical care to improve PTSD treatment, and,
subsequently, evaluate a novel PCMHI-based PTSD treatment as part of a stepped care model for
Veterans who report poor social support and are at great risk of PTSD treatment non-response.
Significance/Impact: The proposed research addresses several HSR&D research priorities,
including evaluating the impact of social determinants of health, namely, social support, on
the quality and outcomes of care; testing new models of mental health care to improve
outcomes; and intervening with vulnerable Veterans with PTSD and suicide risk. By measuring
and improving social support to enhance PTSD treatment, the proposed research plan explicitly
addresses a key factor that impedes treatment outcomes for a sensitive population of
Veterans. Innovation: Although poor social support is widely recognized as among the
strongest predictors of PTSD development and maintenance, none of the existing PCMHI-based
treatments for PTSD target or measure social support as a primary treatment focus. The
proposed CDA-2 research is thus highly novel. No past or present HSR&D-funded studies have
tested methods for monitoring or improving social support in PCMHI-based treatment among
Veterans with PTSD, despite its association with poor clinical outcomes. Specific Aims: 1)
Select an instrument for MBC of social support in clinical settings for Veterans with PTSD.
2) Iteratively refine and conduct a one-arm pilot test a brief, PCMHI-based behavioral
activation and social engagement intervention for PTSD based on key stakeholder (e.g.,
Veteran and PCMHI provider) feedback. 3) Conduct a two-arm pilot randomized clinical trial
(RCT) comparing the intervention to usual care in PCMHI. Methodology: Aim 1 will use
quantitative data gathered in an online survey from 210 Veterans to assess the degree to
which four measures of social support (identified via systematic review and clinical utility
ranking) are acceptable, reliable, and sensitive, and select the best measure for use in Aim
2's pilot. Aim 2 will involve the iterative refinement of the PTSD and social support
intervention following, and followed by, qualitative interviews with key stakeholders. Aim 2
will obtain data on participant acceptability, provider fidelity, and social-support-related
MBC. The pilot RCT comparing the social support and PTSD intervention to usual care in Aim 3
will evaluate the feasibility and acceptability of recruitment, randomization, intervention
engagement, evaluation strategy, and outcome measurement of clinical outcomes (e.g., PTSD,
depression symptoms, and social support), as well as mechanisms of change (e.g., disclosure)
and multiple stepped-care outcomes (e.g., clinically-indicated evidence-based psychotherapy
initiation/retention). Next Steps/Implementation: This work will support future trials
establishing effectiveness and implementation potential of the intervention, as well as a
model of MBC of social support. Future research will explore MBC and PCMHI-based
interventions for poor social support in related conditions.
