<qa>  What is the AUDIT used to describe the effects of the intervention program at the patient levelBesides measurements at the GPT-level, we also conduct measurements at the patient level. All patients of 18 years or older visiting the GPT during a pre-defined 3-month period are asked to fill in the Alcohol Use Disorders identification Test AUDIT. This measurement takes place before the intervention starts. Only those patients at risk are asked to fill in the AUDIT after the intervention ended.

Patients receive individual feedback with personal advice depending on their AUDIT score. Patients are not informed about whether the GPT is allocated to the intervention program or control condition usual care single blind.
