Correlation between intake self-efficacy, and intake function and pain measures (n = 282).

	Intake pain management Self-efficacy	Intake coping with symptoms Self-efficacy
Intake function unadjusted analyses	r = 0.20 95% CI of r = (0.08, 0.34) r2 = 0.04 p-value = 0.0009	r = 0.27 95% CI of r = (0.16, 0.37) r2 = 0.07 p-value < 0.0001
Intake function Adjusted analyses	r = 0.12 95% CI of r = (0.00, 0.23) r2 = 0.01 p-value = 0.05 variables retained in the model: age, gender, third-party payer, exercise history condition index = 21.79	r = 0.21 95% CI of r = (0.10, 0.32) r2 = 0.04 p-value = 0.0004 variable retained in the model: exercise history condition index = 10.86
Intake pain Unadjusted analyses	r = −0.16 95% CI of r = (−0.28, −0.05) r2 = 0.03 p-value = 0.005	r = −0.21 95% CI of r = (−0.32, −0.09) r2 = 0.04 p-value = 0.004
Intake pain Adjusted analyses	r = −0.10 95% CI of r = (−0.22, 0.02) r2= 0.01 p-value = 0.09 variables retained in the model: age, gender, third-party payer, exercise history condition index = 18.44	r = −0.17 95% CI of r = (−0.28, −0.05) r2 = 0.03 p-value = 0.005 variables retained in the model: exercise history condition index = 5.23
