Resilience after the Deepwater Horizon oil spill

The purpose of this paper is to examine the extent to which self-reported resilience was associated with mental health outcomes four years after the Deepwater Horizon oil spill (DWHOS).

Participants included 179 men and women randomly selected from two Northeast Gulf Coast communities as part of a larger, prospective study of behavioral health post oil spill. The majority of the participants were Caucasian (70.8 percent), female (61.5 percent), had a high school education or lower (75.3 percent), and ranged in age from 18 to greater than 60 years old. Participants completed a measure of resilience (Connor-Davidson Resilience Scale, CD-RISC) 2.5 years post oil spill and measures of overall mood disturbance (Profile of Mood States), depression (Beck Depression Inventory), quality of life (World Health Organization Quality of Life-BREF Scale) 4.5 years post oil spill.

Based upon linear regression analyses, elevated self-reported resilience significantly predicted lower scores on mood disturbance (b=−0.63, p<0.01) and depressive symptoms (b=−0.14, p<0.05) and higher scores on psychological (b=0.08, p<0.01) and overall health quality of life (b=0.08, p<0.01). Factor analysis of the CD-RISC identified three factors (hardiness, adaptability, optimism). Each factor predicted some, but not all, of the outcomes with optimism being the least predictive of mental health.

Self-reported resilience two years after the DWHOS was a useful predictor of mental health outcome four years post-spill. Early assessment may facilitate the identification of individuals at risk of longer-term mental health problems for public health prevention or mental health intervention efforts.
