 Participants will be recruited through Amazons MTurk crowdsourcing platform. Potential participants identified as problem drinkers based on an initial survey will be invited to complete another survey in 6 months time. Those who agree to be followed-up will be randomized to be provided a link to download the Alcooquizz app or to a no link 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 that asks about their drinking and their impressions of the app. The primary hypothesis to be tested is that participants receiving access to the Alcooquizz app will report a greater level of reduction in number of drinks in a typical week between the baseline survey and six-month follow-up as compared to participants in the no information control condition.
