Results of Linear Regression Analysis for Primary Outcomes and Predictors

Expectation Variable	Change in Roland at 5 Weeks β-Coefficient (confidence interval)	Change in Roland at 12 Weeks β-Coefficient (confidence interval)
General (unadjusted)	0.96 (0.56, 1.36) (p < .0001; n = 400)	0.87 (0.46, 1.29) (p < .0001; n = 387)
General (adjusted)*	0.80 (0.43, 1.16) (p < .0001; n = 376)	0.59 (0.21, 0.98) (p = .0027; n = 365)
Specific (unadjusted)	0.12 (−0.35, +0.60) (p = 0.61; n = 245)	0.14 (−0.63, +0.36) (p = 0.59; n = 239)
Specific (adjusted)	Not performed	Not performed

*General expectations in model are adjusted for factors including age, race, income, baseline Roland score, depression, history of sciatica, 1st time seeing MD for back pain, and baseline pain score.
