Outcome Measures

Primary Outcomes (1)

  • Change in alcohol consumption and Working memory function

    The difference in alcohol consumption (change from baseline) between the intervention and non-intervention group will be assessed by Time Line Follow Back (TLFB) outcome "percent of heavy drinking days" (heavy drinking day = 4/5 standard drinks in one day for women/men). Change in working memory function will be assessed by score on the Digit Span task and the CANTAB® visuospatial working memory task (high-function mode) pre and post treatment

    Pre and Post Study which is at baseline ( week 0) and end of study (5)

Secondary Outcomes (3)

  • Total number of standard drinks

    On a weekly basis, at baseline, weeks 1-5

  • Craving

    At every visit

  • Executive function

    Pre and post study, at baseline ( week 0) and end of study ( week5)

Study Arms (2)

Cogmed Training

ACTIVE COMPARATOR

Cogmed® working memory training is a computer program that will be administered online. The program consists of 7 verbal and non-verbal working memory tasks and gives immediate performance feedback to the subject undergoing training.

Behavioral: Cogmed training

Standard training

PLACEBO COMPARATOR

Individuals randomised to the placebo arm will receive a standard training online program from Cogmed also consisting of 90 trials to be performed 5 days a week and during a total training period of 5 weeks. In order to complete the study each subject must complete 20 - 25 training sessions within maximum 6 weeks. The program does not increase in difficultly level.

Behavioral: Standard Training

Interventions

Cogmed trainingBEHAVIORAL

Cogmed® working memory training session consists 90 trials and lasts for approximately 30 minutes per day, 5 days a week and during a total training period of 5 weeks (i.e. total training time approximately 12,5 hours). In order to complete the study each subject must complete 20 - 25 training sessions within maximum 6 weeks. The program adjusts the difficulty of the different tasks trial-by-trial, which allows for each subject to train at a level adjusted to his or her current Working memory capacity

Cogmed Training

Standard training session in an online training and also consists 90 trials and lasts for approximately 30 minutes per day, 5 days a week and during a total training period of 5 weeks. In order to complete the study each subject must complete 20 - 25 training sessions within maximum 6 weeks. The program does not increase in difficultly level
