Introduction: The Internet, with its unlimited information, revolutionary communication capabilities, and innovative potential to expand knowledge, is ubiquitous throughout the world, but it also has significant implications for users' mental health. Given the not yet clearly defined and distinguishable nosographic categories of online addiction and the resulting difficulties in describing the impact on users' mental health, the present cross-sectional study aimed to gain new insights into the relationship between Internet addiction (especially social networking site [SNS] addiction), psychological distress, and physical discomfort, as well as gender differences in impact among users.
Method: A sample of 583 Italian speakers (50.8% males; 48.7% females) with a mean age of 30.96 (SD = 12.12) completed an online survey in July 2021. A set of psychometric self-report instruments was administered to assess the study variables. Mediation analyses were performed for both the whole sample and across genders.
Results: The study found that men exhibited higher levels of Internet addiction and craving than women, but no differences were found for SNS addiction. Furthermore, indicators of psychological distress (i.e., anxiety, depression, stress, loneliness, insomnia, and self-esteem) mediated the association between SNS addiction and body uneasiness, with slight differences across genders.
Conclusion: This paper contributes to the existing literature on online addictive behaviors by also highlighting gender differences. The findings underscore the need for educational experiences that can prevent problematic use of the Internet and SNSs.
Keywords: Internet addiction; body uneasiness; psychological distress; self-esteem; social networking sites.
