TABLE 4.

Relationship between evidence-based practice endorsement and mental health.

	EBP endorsement		Non-EBP endorsement			t-test results
Mental health symptoms	Mean	SD	Mean	SD	p-value	Mean difference	Effect size (d)	Confidence interval (CI for Cohen’s d)
Common strategy
Depressive symptoms	1.88	1.55	2.91	2.17	p = 0.002	1.03	0.62	[0.30, 0.94]
Anxiety symptoms	2.53	1.77	3.54	2.20	p = 0.002	1.01	0.55	[0.23, 0.87]
Depressive symptoms (without distraction as EBP)	1.63	1.47	2.34	1.78	p < 0.001	0.72	0.43	[0.20, 0.66]
Anxiety symptoms (without distraction as EBP)	2.37	1.69	2.92	1.97	p = 0.006	0.55	0.30	[0.07, 0.53]
Effective strategy
Depressive symptoms	2.00	1.65	2.30	2.01	p = 0.17	0.004	0.18	[−0.19, 0.54]
Anxiety symptoms	2.69	1.88	2.67	1.83	p = 0.52	0.02	−0.01	[−0.37, 0.35]
Depressive symptoms (without distraction as EBP)	1.96	1.66	2.26	1.76	p = 0.09	0.30	0.18	[−0.08, 0.43]
Anxiety symptoms (without distraction as EBP)	2.72	1.88	2.58	1.87	p = 0.72	0.14	−0.08	[−0.34, 0.18]

Significant p-values are bolded. Depressive symptoms were measured by the PHQ-2 and anxiety symptoms were measured by the GAD-2.
