5. Study Description

Brief Summary
The investigators evaluate the efficacy of a computerised program (T.O.P. tool) consisting of an approach avoidance training (AAT) (to retrain action tendencies for alcohol-related stimuli), a visual probe training (VPT) (to retrain attentional bias for alcohol-related stimuli) and the combination of both training procedures versus placebo training, as an add-on to treatment as usual (psycho-education and cognitive behavioral therapy). The investigators include hospitalized detoxified alcohol-dependent patients, who receive a four week training procedure, existing of a pre-assessment, 6 training sessions and a post-assessment. Outcome measures consist of behavioral measures (consumption of alcohol - self report over 1 year), questionnaires (AUDIT; craving on 9-point likert scale) and approach avoidance and visual probe measurement tasks. A six month and 1 year follow-up is included (behavioral measures and AUDIT). Further, the investigators will also assess credibility (9-point likert scale) of the training procedure before the start of the training and immediately after the assessment of the AAT and VPT training.
