Research on resilience after trauma has often focused on individual-level factors (e.g., extensive trauma history) and overlooked influential neighborhood-level factors that may help mitigate the development of posttraumatic stress disorder (PTSD). We applied geospatial analyses to the AURORA Study dataset and evaluated whether greenspace was associated with PTSD trajectories. We found that individuals with greater exposure to greenspace and higher levels of self-reported individual resources (e.g., ability to cope with adversity) had an increased likelihood of being in a resilient trajectory (low or no symptoms). As a secondary objective, we also examined relationships with neural activity. We found that greenspace was associated with greater neural reactivity to reward within the amygdala, a region involved in detecting and updating the value of rewarding cues. Results suggest neighborhood-level greenspace works in conjunction with individual factors to protect against posttraumatic dysfunction. In addition, our findings emphasize that examining factors at multiple levels (e.g., individual and neighborhood) may improve the early identification of individuals at-risk for developing PTSD and facilitate earlier delivery of effective treatments.<\/p>\n","protected":false},"excerpt":{"rendered":"
