Regression analysis results from the group difference, individual difference, and combined (individual difference + group difference) analytical approaches.

Model Comparisons
Model 1 vs Model 3					12.8	2,105	<.001			0.16
Model 2 vs Model 3					2.55	2,105	.08			0.03

Note. Lower Bayesian Information Criterion (BIC) value is indicative of a preferred model
