Table 7

Hierarchical regression analyses with the domain pain intensity as a dependent variable and mood, DCML, STT, and analgesics as predictors in patients with MS ().

Pain intensity	Beta (SE)	t		F	df			R^2	ΔR^2
Model 1				5.10	1.54	0.03	0.07	0.09	n/a

Model 2				5.92	2.51	0.005	0.16	0.19	0.10
Mood	0.29 (0.03)	2.37	0.02
DCML	−0.32 (0.64)	−2.50	0.02
Model 3				3.91	3.50	0.01	0.14	0.19	n/a
