(1) Public health scholars have noted a relationship between nancial well-being follow-ing catastrophe and rates of depression. Weber, Kenny, and Bratton (2010) examine this relationship in the context of the BP oil spill. During the spill, they interviewed n = 1; 156 residents along the Louisiana coast. The survey included two questions, \Have you been nanciallyaected by the oil spill?" which is coded 1=Yes, 0=No; they also included a question on depression: \How often have you felt depressed?" which is coded 1=often, 0=never/rarely. Below is the cross-tab displaying the relationship between these variables.
