Design outcomes

Primary

Measure	Time frame
Engagement with the intervention: 1. Number of pages visited on the intervention website is measured by reviewing web-usage data (i.e. from a backend database that logs each user's activity on the DBIU website) after completion of the intervention 2. Total time spent on the intervention website is measured by reviewing web-usage data (i.e. from a backend database that logs each user's activity on the DBIU website) after completion of the intervention Alcohol consumption: Number of units of alcohol consumed in a typical week is measured using a retrospective seven-day alcohol diary at 6 months.	—

Measure	Time frame
Engagement with the intervention: 1. Number of strategies/if-then plans made (by increasing risk and higher risk drinkers) is measured by reviewing web-usage data (i.e. from a backend database that logs each user's activity on the DBIU website) after completion of the intervention 2.

Number of units of alcohol consumed in a typical week is measured using a retrospective seven-day alcohol diary at 1 month 2. Number of days drinking in a typical week is measured using a retrospective seven-day alcohol diary at 1 and 6 months 3. Mean units of alcohol consumed on a drinking day is measured using a retrospective seven-day alcohol diary at 1 and 6 months 4. Peak daily consumption is measured using a retrospective seven-day alcohol diary at 1 and 6 months 5.
