Note: AUDIT=Alcohol Use Disorders Identification Test; CUDIT-R=Cannabis use Disorder Identification Test Revised. ROS=region of significance. Low and high ROS range represents the range of SAM operationalizations (i.e., the duration between any one drink and one marijuana use on a given day that delineated SAM from CAM) during which a given variable was a significant predictor of daily subjective intoxication.
Values for “ROS βs” and “ROS range” are not presented when the predictor is not significant for any operationalization.
Low and high values for “All βs” represent the lowest and highest estimate across all SAM operationalizations.
Low and high “ROS βs” represent the lowest and highest estimate within the ROS.
“All βs” are equivalent to “ROS βs” when “ROS range” is 1–240 (i.e., significant in all operationalizations).
p-values are given within the ROS where significant at p < .05.
