Variable	B>	SE	p Value	OR	95% CI
Separate models
Baseline depressive symptoms	0.33	0.16	.03	1.4	1.03–1.89
Self-efficacy at 18 months controlling for self-efficacy at baseline (mediator variable)	−0.04	0.01	<.0001	1.04	1.02–1.05
Both predictors in the model
Baseline depressive symptoms	0.28	0.16	.075	1.3	0.97–1.82
