Table 7 Linear regression: simultaneous alcohol and cannabis expectancies account for variance in the prediction of days per month using alcohol and cannabis simultaneously beyond individual alcohol expectancies or cannabis expectancies.
Days Using Alcohol and Cannabis Simultaneously (df = 2539)
Note: Standardized regression coefficients (βs) derive from the step in which they are added to the equation.
*p < .05 **p < .01 _p = .05 Cannabis per month with alcohol = Metric weight of cannabis consumed when also drinking alcohol. Drinks per month with Cannabis = Number of alcoholic drinks when also consuming cannabis AEQ = Alcohol Expectancies; MEEQ = Cannabis Expectancies.
