Study Details

Study Description

Brief Summary

The purpose of this study is to evaluate the effects of a computerized working memory training program on substance abuse, psychosocial functioning, cognitive performance and psychiatric problems in adults with substance abuse and attention problems.

Condition or Disease Intervention/Treatment Phase
  • Behavioral: Computerized Cogmed working memory training
  • Behavioral: Treatment as usual
Phase 2

Detailed Description

The primary aim of this study is to examine the effects of 5 weeks of computerized working memory training on substance abuse. Secondary aims are to explore whether effects are mediated by changes in executive functions and/or moderated by personality. Also, effects on measures of psychosocial functioning, depression, anxiety and attention will be explored. Follow-up assessment will be conducted at 6 months post training.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Cogmed working memory training

30-40 minutes of Cogmed computerized working memory training 3-5 days a week for 5-8 weeks. Every training session consists of a set of visual- and verbal working memory tasks that are trained on during the session.

Behavioral: Computerized Cogmed working memory training
Computerized working memory training with Cogmed QM software. The QM software consists of a set of verbal and visual working memory tasks which is trained for 25-40 minutes each session.

Active Comparator: Treatment as usual

Treatment as usual can consist of medication, psychotherapy, counseling, and psychological assessment. After a 8 week period participants in this arm well be offered Cogmed working memory training.

Behavioral: Treatment as usual
Treatment as usual can consist of medication, psychotherapy, counseling, and psychological assessment.
