Brief Summary

Objectives: This study evaluates the efficacy of two mobile phone applications, Promillekoll and PartyPlanner among university government members at two universities in Stockholm, Sweden. The design is a three-armed randomized controlled design, and outcomes are measured in terms of changes in problematic alcohol use at follow up 7 weeks after study initiation and baseline data gathering. Both the Promillekoll and PartyPlanner apps feature real time registration of alcohol consumption and giving feedback of estimated blood alcohol concentration levels. Both apps inform and warn the user when the estimated alcohol level is above 0.6%, a level set that is below risky consumption levels. PartyPlanner additionally provides the possibility of simulating and planning an alcohol consumption event in advance and later on comparing it with the real time registration at the event. Method: Participants with problematic alcohol use (AUDIT \>7 for men and \>5 for women) are randomized into one of three groups: 1. Access to Promillekoll, 2. Access to PartyPlanner and 3. Control group. Outcomes on alcohol use as well as information on the users' satisfaction with the app assigned to them gathered after 7 weeks. The hypotheses are: 1. The groups receiving the Promillekoll and PartyPlanner interventions will reduce their alcohol use to a larger extent than the control group at follow-up compared to the baseline level. 2. The addition of the possibility to plan events beforehand (PartyPlanner) will lead to an increased decrease in alcohol consumption to only real-time use (Promillekoll).
