Addiction Risk: Psychoeducational Intervention to Change Risk Perception Among Alcohol Patients in Residential Treatment

Study Overview
=================
Brief Summary
-----------------
Based on previous research (Odenwald & Semrau, 2012) the investigators know that psychoeducation on comorbid mental disorders during residential alcohol detoxification can improve subsequent treatment utilization. In this study they will study a hypothesized psychological mechanism that contributes to this behavior change. The investigators will recruit alcohol dependent patients in residential detox treatment who all receive Treatment as Usual. Participants will be randomly assigned to an additional psychoeducational group therapy (intervention group) or to an additional neuropsychological group training (control group). Measurements will take place on the day before study inclusion, one week later and one month after release from index residential treatment. Measurements will include alcohol-related risk perception, alcohol use, treatment motivation, comorbid psychiatric symptoms and whether the patient has regularly completed treatment and whether he/she has been transferred to subsequent treatment. Furthermore, six months after release from index treatment information on re-admission to the clinic is assessed from patient files. The investigators hypothesize that the behavioral effects of psychoeducational group intervention will be mediated by adaptive changes of the individual's alcohol-related risk perception.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Questionnaire on Alcohol-related Risk Perception | The patient's self-reported rating of the patient's own perception of alcohol-related risks in the German Questionnaire on Alcohol-related Risk Perception (Klepper, Odenwald & Rockstroh, 2016). | one week | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Treatment completion | Binary variable: The patient regularly completes the residential detox treatment or he/she can prematurely end the treatment (treatment drop out). | One month after study completion | 
| Transfer to subsequent treatment | Binary variable: Patient is directly transferred from detox treatment unit to subsequent alcohol in-patient or day-clinic treatment. | One month after study completion | 
| Alcohol relapse | Drinking alcohol after treatment | four weeks | 
| Readmission to detox treatment | The patient is readmitted to the same alcohol detox treatment unit | six months |
