The effects of emotional working memory training on internet use, impulsivity, risky decision-making, and cognitive emotion regulation strategies in young adults with problematic use of the internet: A preliminary randomized controlled trial study into possible mechanisms

Abstract Introduction Considering adverse correlates of problematic use of internet use (PUI), the present study evaluated an intervention aimed at PUI and several putative underpinnings. Methods A randomized controlled trial study investigated the efficacy of emotional working memory training (eWMT) in improving impulsivity, risky decision-making, and cognitive emotion-regulation (CER) strategies among individuals with PUI in comparison with a placebo group. Young adults ( N = 36) with PUI were either trained for 20 sessions in an n-back dual emotional task (eWMT; n = 18) or a feature-matching task (placebo; n = 18). Results Twenty continuous sessions of eWMT significantly improved participants' impulsivity, risky decision-making, CER, internet use and PUI symptoms in the short term, compared to the placebo condition. Discussion These preliminary results suggest that eWMT may constitute a promising intervention for PUI and improving cognitive and emotional functioning, and larger, longer studies are warranted.
