This study evaluates the efficacy of a skills training web-based mobile phone application, Telecoach among individuals in the general population seeking help for their risky alcohol consumption on the Internet. The design is a two-armed randomized controlled design, and outcomes are measured in terms of changes in excessive alcohol use at follow up 6, 12 and 26 weeks after study initiation and baseline data gathering. The Telecoach web app delivers skills training in the form of exercises commonly used in psychosocial interventions for risky alcohol use. The controll condition is a web app providing information on the effects of alcohol on the consumers' health.
This study evaluates the efficacy of a skills training web-based mobile phone application, Telecoach among individuals in the general population seeking help for their risky alcohol consumption on the Internet. The design is a two-armed randomized controlled design, and outcomes are measured in terms of changes in excessive alcohol use at follow up 6, 12 and 26 weeks after study initiation and baseline data gathering.
Individuals seeking help for problematic alcohol use on the internet will get access to a webpage with information about the study. Individuals leaving informed consent are asked to fill out questionnaires about alcohol use, depression, anxiety and information on gender and weight. Those with excessive alcohol use (>14 standard glasses/week for men and > 9 for women) are randomized into one of two groups: 1. Access to the Telecoach web-app and 2. Access to a control condition with an information-providing web-app.
Outcomes on alcohol use are gathered by electronic self-registration at 6, 12 and 26 weeks after study initiation. Additional questions on the users' satisfaction with the app assigned to them and other support for problematic alcohol used during the research period at 26 weeks.
The Telecoach web-app is a skills-training app developed for use on a mobile smart-phone. The skills-training components are common to psychosocial treatment protocols for problematic alcohol consumption.
The control condition web-app is a simple text-based app providing information on the effects of alcohol on the consumers' health.
Outcomes will be reported, analyzed and discussed in a scientific article.

Note: A pilot period with interim 6-week analyses following recruitment of about 10% of the maximum anticipated sample of 1000 is part of the study. This offers an opportunity to assess trial continuation from an ethical perspective. The rationale for this is that individuals with relatively severe levels of alcohol use can be included in the trial and the investigators harbor a concern that the components in the intervention and control conditions might be insufficient to support the participants in remaining stable or reducing their alcohol intake. The pilot period covers a recruitment period from Dec 7, 2019 to February 15, 2019 (n=89) and includes a 6-week follow-up. The interim analysis from May 1, 2019 indicates group declines in alcohol use over the 6-week follow-up period for both conditions, suggesting that continuation of the trial is warranted. Pilot participants will be included in the final study sample.
