Notes. Correlation coefficients above the diagonal were estimated from the unadjusted models whereas coefficients below the diagonal were estimated from the adjusted models. I1=Positive alcohol expectancies (PAE) intercept, S1=Positive alcohol expectancies slope; I2=Negative alcohol expectancies (NAE) intercept; S2=Negative alcohol expectancies slope. I3=Positive cigarette expectancies (PCE) intercept; S3=Positive cigarette expectancies slope; I4=Negative cigarette expectancies (NCE) intercept; S4=Negative cigarette expectancies slope. I5=Positive marijuana expectancies (PME) intercept; S5=Positive marijuana expectancies slope; I6=Negative marijuana expectancies (NME) intercept; S6=Negative marijuana expectancies slope. SE=Standard Error. Standardized estimates are provided.
