Change From Baseline Typical Weekly Drinking at 1 Month |
At baseline and the 1-month follow-up, participants reported the typical quantity of standard alcohol drinks consumed on each day of the week during the past 30 days using the Daily Drinking Questionnaire. Quantity of drinks reported on each day of the week at baseline and 1-month were then summed (separately) to create a composite variable assessing typical weekly drinking at each time point. To compute the outcome, the 1-month measure of typical drinks per week was subtracted from the baseline measure of typical drinks per week such that a positive value indicates a decrease in consumption during this period and a negative value indicates an increase in consumption during this period. |

Change From Baseline Typical Weekly Drinking at 6 Months |
At baseline and the 6-month follow-up, participants reported the typical quantity of standard alcohol drinks consumed on each day of the week during the past 30 days using the Daily Drinking Questionnaire. Quantity of drinks reported on each day of the week at baseline and 1-month were then summed (separately) to create a composite variable assessing typical weekly drinking at each time point. To compute the outcome, the 6-month measure of typical drinks per week was subtracted from the baseline measure of typical drinks per week such that a positive value indicates a decrease in consumption during this period and a negative value indicates an increase in consumption during this period. |

Change From Baseline Frequency of Alcohol Consequences at 1 Month |
At baseline and the 1-month follow-up, the number of types of negative alcohol-related consequences experienced out of a list of 14 common negative alcohol-related consequences (past 30 days) were summed to create a composite variable at each time point. To compute the outcome, the 1-month measure of negative consequences was subtracted from the baseline measure of negative consequences such that a positive value indicates a decrease in consequences during this period and a negative value indicates an increase in consequences during this period. |

Change From Baseline Quantity/Frequency/Peak Alcohol Use at 1 Month |
At baseline and the 1-month follow-up, an item assessing the number of maximum drinks on one occasion from the Frequency, Quantity, Max (FQM) measure was used to assess peak drinks on one occasion over the past 30 days. To compute the outcome, the 1-month measure of peak drinks was subtracted from the baseline measure of peak drinks such that a positive value indicates a decrease in consumption during this period and a negative value indicates an increase in consumption during this period. |

Change From Baseline Heavy Episodic Drinking at 1 Month |
At baseline and the 1-month follow-up, an item assessing the number of times students reported a heavy episodic drinking (HED) event in the past two weeks. To compute the outcome, the 1-month measure of HED was subtracted from the baseline measure of HED such that a positive value indicates a decrease in HED events during this period and a negative value indicates an increase in HED events during this period. |
