Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
One promising strategy is Internet-based interventions for problem drinkers. Our recently completed RCT comparing a brief (Check Your Drinking; CYD) versus an extended (Alcohol Help Centre; AHC) Internet intervention for problem drinkers found that, while there was a reduction in drinking across time for both interventions, there was no significant (p \> .05) difference in reductions in drinking between the two interventions. Based on these results, it is not justifiable to say that either intervention 'worked' as there was no comparison condition of participants who received no active intervention. The current trial proposes to address this limitation by conducting an RCT comparing the CYD, AHC, and a no intervention control condition.
Participants will be recruited through Amazon's MTurk crowdsourcing platform. Participants identified as problem drinkers based on an initial survey will be invited to complete another survey in 6 months time. Those who are interested will be randomized to receive access to the Check Your Drinking screener (CYD condition), Alcohol Help Centre (AHC condition) or a feedback questionnaire (control condition). At six-months post-baseline, the MTurk portal will be used to send invitation emails that contain a link to the follow-up survey. The primary hypothesis to be tested is that participants receiving access to the AHC intervention will report a greater reduction in AUDIT-C scores and in number of drinks in a typical week than participants in the CYD intervention. Further, participants in the CYD condition will report a greater level of reduction AUDIT-C scores and in number of drinks in a typical week between the baseline survey and six-month follow-up as compared to participants in the no intervention control condition.

No interventions assigned to this group
Check Your Drinking (CYD)
Internet based program of lower intensity as compared to the "Alcohol Help Centre. It was designed to provide personalized normative feedback aimed at motivating reductions in drinking
CYD
Alcohol Help Centre (AHC)
Internet based program of higher intensity as compared to the "Check Your Drinking" intervention. It was designed to assesses drinking patterns, increase self-awareness of individual triggers, and set and achieve goals regarding drinking.
