Note. Depressive symptoms and covariates were assessed at baseline, whereas medical morbidity was assessed biennially from 2006 to 2014. Change in -2 log likelihood for the full model (16,573.94) is based on comparison with a covariate-only model (16,604.57). Estimates are presented from the full model.
