Hierarchical regression analyses for marijuana consequences outcome

Model 1 – Positive Expectancies Estimate SE P-value
Step 1: Frequency of consequences in past 30 days regressed on MHI-5 and positive expectancies
MHI-5 −0.10 0.04 0.004
Positive expectancies 0.18 0.05 < .001
Step 2: Frequency of consequences in past 30 days regressed on interaction of MHI-5 and positive expectancies
MHI-5 x Positive expectancies −0.12 0.05 0.014
Model 2 – Negative Expectancies
Step 1: Frequency of consequences in past 30 days regressed on MHI-5 and negative expectancies
MHI-5 −0.12 0.04 0.001
Negative expectancies −0.03 0.03 0.284
Step 2: Frequency of consequences in past 30 days regressed on interaction of MHI-5 and negative expectancies
MHI-5 x Negative expectancies 0.02 0.04 0.508

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