Excessive digital gaming can have unfavorable effects on gamers’ well-being and everyday functioning. The aims of this study were to investigate the effects of a novel group intervention “Limitless Gaming Bootcamp” on (i) gaming disorder (GD) tendencies, (ii) the amount of time spent on leisure activities, and (iii) subjective well-being among Finnish young adults, and to determine the persistence of the intervention’s influence over time. A one-group pre- and post-test design with no control group was used. Thirty-seven participants were enrolled in the study. The inclusion criteria were being between the ages of 18 and 29; self-reported excessive gaming; a willingness to get support in monitoring one’s gaming behaviour; and a fluency in Finnish. Participants completed a 10-session group intervention designed to enhance conscious gaming behavior and well-being. Baseline, post-test, and six month follow-up measurements were conducted to gather data. Variables measured included background variables, gaming disorder tendencies (Problematic Online Gaming Questionnaire, POGQ), self-reported time spent on various leisure activities, and subjective well-being (Short Form of the Clinical Outcomes in Routine Evaluation Outcome Measure, CORE-SF/A). The time spent on gaming decreased from pre- to post-intervention measurement and further to the six month follow-up, and participants exhibited less severe GD symptoms during the post-intervention phase and six months after the intervention. Gradual improvements in subjective well-being were also observed. The group intervention was found to be particularly effective at reducing the severity of GD symptoms.
