Predictors of time to post-acute outcomes from clinically significant sleep disturbance.

Model: Outcome	Predictor	Beta	SE	HR
1: Relapse (8 months)	PSQI ≥ 5	−0.004	0.328	1.00
2: Relapse/recurrence (32 months)	PSQI ≥ 5	−0.085	0.234	0.92
3. Post-acute remission (32 months)	PSQI ≥ 5	−0.366*	0.175	0.69
4. Recovery (32 months)	PSQI ≥ 5	−0.530**	0.199	0.59

Note. N = 241. Models are Cox regression. PSQI = Pittsburgh Sleep Quality Index. HR = hazard ratio. All models controlled depression-symptom severity at randomization to continuation treatment, as well as continuation-treatment arm (cognitive therapy, fluoxetine, or pill placebo with clinical management). Non-significant (p > .05) interactions of sleep problems with treatment arm were removed from the final models.
