A Working Memory Training to Decrease Rumination in Depressed and Anxious Individuals

18. april 2014 opdateret af: Ingmar Franken, Erasmus Medical Center

A Working Memory Training to Decrease Rumination in Depressed and Anxious Individuals: A Double-blind Randomized Controlled Trial

Dysfunctioning executive functioning, including working memory (WM), is related to rumination. Findings show that working memory capacity (WMC) can be increased by training. The current study explored by means of a double-blind randomized controlled trial whether an adaptive WM training could reduce rumination, anxiety and depression in a sample of 98 depressed and anxious individuals.
