Prior studies of oil spills have reported adverse impacts on mental health, but have not examined some potentially important moderators. In this cross-sectional analysis of n=38,361 responses to the 2010-2011 Gulf States Population Survey, we assessed the association of direct oil contact with depression severity following the Deepwater Horizon oil spill, and modification by self-mastery, emotional support, and cleanup participation using Tobit regression models accounting for the complex survey design. Oil contact was associated with increased depression severity. Among respondents with oil contact, depression was more severe for those reporting lower self-mastery. However, respondents with oil contact had lower depression severity if they participated in cleanup efforts, compared to exposed individuals who did not participate. This potential protective effect was larger for respondents with lower self-mastery. Our results are consistent with the notion that participation in recovery efforts may reduce depressive symptoms following oil spills among impacted individuals.

深水地平线溢油后抗压降机制

先前对石油泄漏的研究报告了对心理健康的不利影响，但没有检查一些潜在的重要调节因素。在对 2010-2011 年海湾国家人口调查的 n=38,361 响应的横断面分析中，我们评估了深水地平线石油泄漏后直接接触石油与抑郁症严重程度的关联，以及通过自我控制、情感支持和使用 Tobit 回归模型进行清理参与，解释了复杂的调查设计。石油接触与抑郁症的严重程度增加有关。在接触过石油的受访者中，那些报告自我控制能力较低的人的抑郁症更为严重。然而，与没有参与清理工作的接触者相比，接触过石油的受访者如果参与清理工作，他们的抑郁症严重程度较低。对于自我掌握程度较低的受访者，这种潜在的保护作用更大。我们的结果与参与恢复工作可能会减少受影响个人在石油泄漏后的抑郁症状的观点一致。
