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

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.
