Abstract

Although increases in the prevalence of mental distress have been reported after natural disasters, less is known about the role the environment may play in mitigating posttraumatic stress disorder (PTSD) in hurricane-impacted communities. This study aims to investigate the extent to which concentration and perceived quality of neighborhood greenness are associated with lower levels of PTSD, along with potential mechanisms through which these effects occur. We conducted a cross-sectional survey of individuals (N=272) from 30 Houston neighborhoods that were affected during Hurricane Harvey. Perceived quality of neighborhood green space was measured using a scale adapted from the Neighborhood Open Space (NOS) scale, and concentration of greenness was measured objectively using the normalized difference vegetation index (NDVI). Probable PTSD was measured using the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5), and hurricane-related distress using the Impact of Event Scale (IES-R). Generalized linear mixed models were used to fit individual models. Based on the results, structural equation models were employed to test direct and indirect pathways simultaneously. Models were adjusted for neighborhood- and individual-leve...Continue Reading
