Summary

The purpose of the study is to evaluate the effects on alcohol consumption, and the consumption of time spent by a qualified clinician, by adding different forms of guidance to a digital intervention based on an alcohol diary and techniques from cognitive behavioral therapy and relapse prevention. The participants will be adults with problematic alcohol use. The trial will be a 2\*2 factorial experiment where written guidance and/or an extra mid-treatment telephone interview will be added to the basic digital intervention, by randomization. The randomized factorial experiment will create four equally large groups (1:1:1:1) who will receive different combinations of added guidance. Main outcome will be effects on alcohol consumption. Effects on alcohol consumption will also be combined with clinician time spent on guidance to assess the resource-effectiveness of added forms of guidance.
