Overview
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.
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.
