Summary description of the study

Background: Alcohol abuse is one of the most common risk factors for health problems and premature deaths among adolescents and young adults worldwide. Despite the availability of effective treatments for alcohol use disorders (AUD), there is a need to enhance their effectiveness and expand accessibility. Initial research findings suggest that alcohol-specific control training – as an adjunct to specialized treatment – improves treatment outcomes. This training is designed to enhance alcohol-specific control. Project Objective: In our research project, this training will be implemented for the first time in the form of an app, increasing the availability and attractiveness of the training. The aim of the project is to evaluate the feasibility of this new app-based cognitive training as an adjunct to the treatment of AUD in adolescents and young adults. Additionally, initial insights into the effectiveness on drinking behavior and the neurophysiological effects of the training will be investigated. Procedure: The project will be conducted as a double-blind, multicenter clinical pilot study. A total of 210 adolescents and young adults aged 14 to 27 will be recruited from five specialized treatment centers. After the first appointment, participants will be randomly assigned to one of two study conditions: 1) the intervention with alcohol-specific control training or 2) a control condition that includes a non-alcohol-specific control training. During the study participation, participants will be guided through six short training sessions, followed by six booster training sessions after approximately one month.

Intervention under investigation

In the alcohol-specific control training, alcohol-related and neutral images are shown in combination with a Go or No-Go cue. Participants are asked to press a button as quickly as possible when an image is displayed with a Go cue. When an image with a No-Go cue appears, participants should refrain from responding as much as possible. Alcohol-related images are specifically combined with No-Go cues, and the ratio of Go to No-Go cues is 75/25. A training session lasts approximately 10 to 15 minutes. The training is offered within an app to increase accessibility.
