Hierarchical regression analyses for marijuana use outcome

Model 1 – Positive Expectancies	Estimate	SE	P-value
Step 1: Days used in past 30 days regressed on MHI-5 and positive expectancies
MHI-5	0.03	0.17	0.840
Positive expectancies	1.57	0.19	< 0.001
Step 2: Days used in past 30 days regressed on interaction of MHI-5 and positive expectancies
MHI-5 x Positive expectancies	−0.22	0.21	0.299
Model 2 – Negative Expectancies
Step 1: Days used in past 30 days regressed on MHI-5 and negative expectancies
MHI-5	−0.13	0.18	0.473
Negative expectancies	−1.09	0.22	< 0.001
Step 2: Days used in past 30 days regressed on interaction of MHI-5 and negative expectancies
MHI-5 x Negative expectancies	0.13	0.25	0.604

Note: MHI-5 = Mental Health Index-5 composite score. Standard errors and p-values estimated from 1000 bootstrap samples. Significant effects are in bold.
