Problematic Internet Use in Emerging Adulthood

Research has shown the importance of exploring variables associated with problematic Internet use (PIU) in emerging adulthood. In this scenario, grandiose and vulnerable narcissistic features might be differently associated with PIU. Similarly, environmental sensitivity encompasses heightened empathy, sensitivity to rejection, and problems in emotional regulation. However, the interplay of narcissism and environmental sensitivity associated with PIU has not yet been explored. In this scenario, in a sample of 319 emerging adults (female = 78%, M-age = 24.00, SD = 2.33), we explored the role of environmental sensitivity in the association between narcissistic features and PIU using general linear models that were compared via a total coefficient of determination (TCD) and Akaike information criterion (AIC). Data highlighted that one emerging adult out of four displayed at least a moderate level of PIU. Furthermore, results showed that only narcissistic vulnerability was associated with PIU. Also, findings suggest that higher sensitivity to environmental stimuli (positive or negative ones) strengthens the association between vulnerable narcissism and PIU. Our study sheds light on the complex and multidimensional nature of PIU, acknowledging the interaction between different personality traits linked to an increased sensitivity to the social world: environmental sensitivity, including the environmental and social cues, and narcissistic features, encompassing the fear of rejection and/or devaluation from others. By exploring these associations, this study highlights the need for more targeted interventions to address PIU, particularly for individuals with higher levels of self-sensitivity when navigating the interpersonal domain.
