Multivariable Random Effects Model Predicting Time Spent Discussing Exercise

Fixed Effect	Coefficient	SE	P
CCM score	0.21	0.06	<.01
Length of time (min)	0.03	0.03	.36
Age (years)	−0.01	0.01	.22
Female Sex	−0.46	0.21	.04
Acute visit	−0.64	0.31	.05
Maintenance SOC for exercise	−0.27	0.23	.27
Precontemplation SOC for exercise	−1.03	0.27	<.01

Dependent variable: number of 15-second intervals spent discussing exercise. CCM was adjusted for all of the other variables included in the model.
CCM, Chronic Care Model; SOC, stage of change.
