Fig. 1.

We report the standardized parameter estimates (and the 95% confidence intervals within square brackets) for both the depressive symptoms (upper line) and the anxiety symptoms (lower line) models. Single-headed arrows reflect regression and two-headed arrows correlation effects. The thick lines and the bold font highlight the mediation pathway. Both models were controlled for age, sex, educational level, and living alone by regressing each of the main variables (at both waves) on each of these covariates. w1 = wave 1, w2 = wave 2.
