Note: Data was pooled across the 3-, 5-, 9-, and 15-year surveys. Work characteristic coefficients and 95% confidence intervals shown. Model 1 included all time-stable covariates (measured prior to multiple job holding/mental health measures). Model 2 included the same set of controls as Model 1, but included time-varying covariates where applicable. Model 3 included time-varying work characteristics, individual fixed-effects, and year fixed-effects. Model 4 included individual fixed-effects controlling for year fixed-effects and including time-varying work characteristics and other covariates. Sample was restricted to women who worked in the 12 months prior to survey, but hours at main job included a “no work” category in Model 1 because employment characteristics were measured at the 1-year survey. Sample size was n = 2,933 (7,844 observations).
