Regression results predicting QIDS-4 sleep subscale and PSQI-1 scores from grief severity

	QIDS-4		PSQI-1
	Statistic	P-value	Statistic	P-value
Model	F(5, 383) = 7.58	<.001
ICG score	B = 0.034	.015	B = 0.04	.001
MDD comorbidity	B = 0.92	.001	B = −0.73	.002
PTSD comorbidity	B = 0.75	.003	B = −0.65	.003
Gender	B = −0.26	.38	B = 0.05	.86
Age	B = 0.03	.55	B = 0.003	.64

Note. QIDS-4 = Quick Inventory of Depression Symptoms 4 sleep disturbance items; PSQI-1 = Pittsburgh Sleep Quality Index, grief-anchored sleep disturbance item; ICG = Inventory of Complicated Grief; MDD = major depressive disorder; PTSD = posttraumatic stress disorder. Model included gender, age, and comorbid baseline diagnoses of MDD and/or PTSD.
