Multiple linear regression of pain duration and functioning scores on the number of CAM and mind-based approaches selected

Dependent variable	Variables entered	β	Model R2	Adjusted R2
Number of CAM	Pain duration	0.32**	0.14	0.10
	Physical functioning	−0.15
	Physical role functioning	0.06
	Family activities	−0.13
Number of mind-based	Pain duration	0.22*	0.14	0.10
	Physical functioning	−0.16
	Physical role functioning	0.08
	Family activities	−0.25*

β, standardized regression coefficient; Model R², coefficient of determination (goodness of fit) for overall regression model after entry of each independent variable; change in R², incremental contribution of an independent variable to R² in the total set of independent variables; **P < 0.01, *P < 0.05.
