Table 4. Coefficients from logistic regression models of past-month depression, Mississippi Community Study, 2007a.
Coefficients and 95% confidence intervals from logistic regression models of past-month depression. Coefficients in Model 1 are not adjusted for other variables. Model 2 adjusted for displacement, low county social cohesion, Black race, sex, age, educational attainment, number of lifetime PTSD symptoms, county percent population aged 25+ with at least a bachelor’s degree, and county percent occupied housing units with major or severe damage from Hurricane Katrina. Model 3 = Model 2 + displacement x low county social cohesion interaction. Model 4 = Model 3 + individual perceived social cohesion score. Model 5 = Model 3 + social support tertile. Model 6 = Model 3 + individual perceived social cohesion score and social support tertile.

Sample limited to respondents who reported being of non-Hispanic black or white race and who did not change their county of residence after Hurricane Katrina. N=708; weighted N=1533.
Average value over 25 imputations; −2 log likelihood for intercept-only model = 622.12; −2 log likelihood for model including only social cohesion, displacement, and their interaction = 554.86.
