Notes. All models control for frequency of interaction with, emotional closeness to, and kin composition of W1 confidants, religious attendance, and the intercept. CES-D = CES-D = Center for Epidemiologic Studies Depression scale.
aCoefficients are unstandardized coefficients from OLS regressions, and standard errors are presented in parentheses below these estimates. Number of W1 confidants is controlled using a set of dummy variables indicating baseline network size.
bCoefficients are incidence rate ratios, and standard errors are presented in parentheses below these estimates. Number of W1 confidants is used as the exposure.
cCoefficients are incidence rate ratios, and standard errors are presented in parentheses. W2 network size is used as the exposure, and W1 network size is controlled using a set of dummy variables indicating baseline network size.
