Surviving the storm: Avoidant coping, helping behavior, resilience and affective symptoms around a major hurricane-flood.

Background: As extreme weather events increasingly affect the global population, it is valuable to understand their impacts on mental health. Extending upon previous theory and research, the current study examined a hypothesized framework of direct and indirect pathways. Exposure and psychosocial resource factors at the time of the hurricane/flood were expected to help explain post-disaster behavioral responses, such as avoidant coping, positive coping, and helping behaviors, which, in turn, would help account for post-traumatic stress symptoms (PTSS) and depressive symptoms (DS).

Methods: Survey data were collected from adult survivors (n = 801) of Hurricane Harvey 1-3 months post-disaster. PTSS, DS, and needing help were common, and loss/disruption and helping behavior were widespread. Structural equation modeling was used to examine the hypothesized framework.

Results: Models accounted for substantial variance in PTSS (70%) and DS (61%), with immediate loss/disruption, low self-reported resilience, and avoidant coping showing the strongest associations with symptoms. As predicted, results provided support for several modeled indirect pathways through avoidant coping to PTSS and DS. Further, helping behavior was consistently associated with increased PTSS, but not DS.

Limitations: Cross-sectional design and online data collection methods precluded testing of causal directionality and confirming clinical diagnoses.

Conclusions: The current study represents a step toward elucidating potential mediators of avoidant coping and how helping behavior might relate to post-disaster psychopathology. Individuals in heavily hurricane/flood-exposed areas who have low psychosocial resources (social support and resilience) might be most vulnerable and most in need of intervention.
