Given the increasing use of technology among emerging adults, this study evaluated emoWELL, a serious game designed to enhance emotion regulation during this developmental stage.MethodsUsing a quasi-experimental design, 114 university students in emerging adulthood (aged 18–25) were assigned to either an experimental group using emoWELL or a control group. Analyses included MANOVA, MANCOVA, hierarchical multiple regression, Reliable Change Index (RCI), moderation, mediation, and qualitative analyses of participants’ feedback.ResultsSignificant improvements were observed in the experimental group (Wilks’ λ = .68; F = 2.59; p = 0.003; η2 = .32), particularly in reducing expressive suppression strategy, emotional rejection, lack of emotional control, and overall emotion dysregulation. Mediation analyses revealed that enhanced emotion regulation indirectly improved self-acceptance and environmental mastery. Moderation analyses indicated that baseline anxiety and depression levels influenced the intervention’s effectiveness, with fewer symptom levels associated with better emotional outcomes post-intervention. The game received positive user feedback, particularly regarding its psychoeducational content and emotional awareness components.DiscussionWhile emoWELL shows promise as a preventive tool for emotion regulation in emerging adults with low emotional symptomatology, its effectiveness may be limited for those with elevated anxiety and depression levels, suggesting its optimal use as a complementary tool under professional supervision or in university settings with appropriate support.
