NCT04283305

Brief Summary

The approach-avoidance training program (AATP) has shown preliminary promise as an add-on to standard treatment for alcohol dependence. However, knowledge is lacking as to whether the effectiveness of AATP can be enhanced further when performed in a typical drinking situation. The main aim of this study is to investigate whether approach-avoidance training implemented in a virtual reality bar environment is superior to the classical joystick PC-version of the AATP.

Outcome Measures

Primary Outcomes (1)

  • Changes in alcohol consumption

    Alcohol consumption measures will be derived from the Timeline Followback (TLFB). The TLFB method involves using a calendar to identify alcohol consumption patterns in terms of number of drinks per day during the last 30 days. One drink is defined as 12 grams of ethanol. The Visual Analogue Scale (VAS) comprises single items used to measure the degree of alcohol cravings on scales ranging from 0-100, with 0 representing no cravings and 100 an extreme degree of cravings. The scale is presented visually on a ruler, and the individual will be requested to report the frequency, mean level and the peak level of cravings experienced during the last 30 days.

    at baseline (day 0), at post-test (right after 14 days training period) and at follow up (84 days after post-test)

Secondary Outcomes (4)

  • Changes in alcohol-related craving

    at baseline (day 0), at post-test (right after 14 days training period) and at follow up (84 days after post-test)

  • Changes in alcohol abstinence self-efficacy

    at baseline (day 0), at post-test (right after 14 days training period) and at follow up (84 days after post-test)

  • Changes in impulsivity

    at baseline (day 0), at post-test (right after 14 days training period) and at follow up (84 days after post-test)

  • Changes in depression severity

    at baseline (day 0), at post-test (right after 14 days training period) and at follow up (84 days after post-test)

Other Outcomes (3)

  • Changes in Alcohol related Approach Bias

    at baseline (day 0), at post-test (right after 14 days training period) and at follow up (84 days after post-test)

  • Changes in cue-induced cravings

    at baseline (day 0), at post-test (right after 14 days training period) and at follow up (84 days after post-test)

  • Changes in alcohol-related response inhibition

    at baseline (day 0), at post-test (right after 14 days training period) and at follow up (84 days after post-test)

Study Arms (3)

Virtual reality approach avoidance training

EXPERIMENTAL

Participants will receive six sessions (three sessions per week for two weeks; session duration = 30 mins) of approach-avoidance training in the virtual reality. Alcoholic beverages are pushed away with a controller and soft-drinks will be pulled towards oneself. Training will begin approximately three weeks before discharge from the inpatient clinics to measure the add-on effect and to ensure that the add-on treatment does not extend the treatment period.

Other: Virtual reality approach avoidance training

Computer-based approach avoidance training

ACTIVE COMPARATOR

Participants will receive six sessions (three sessions per week for two weeks; session duration = 30 mins) of approach-avoidance training on the computer. Alcoholic beverages are pushed away with a joystick and soft-drinks will be pulled towards oneself. Training will begin approximately three weeks before discharge from the inpatient clinics to measure the add-on effect and to ensure that the add-on treatment does not extend the treatment period.

Other: Computer-based approach avoidance training

Treatment as usual

NO INTERVENTION

Participants will receive treatment as usual on the wards. For ethical reasons, participants in this condition will get the offer to undertake the already scientifically validated computer-based approach avoidance training after their completion of the study.

Interventions

In the VR-based AAT, patients are situated in a bar environment where drinks appear on a bar table in front of them. Patients are instructed to react to 100% of the alcoholic beverages with a push response with a controller, and to non-alcoholic drinks in 100% of the trials with a pull response. The stimuli set consists of 50 different beverages, which are displayed three times in total.
