The digital tether: a SA-SV based survey on smartphone addiction among young adults in Southern Italy

Introduction. In the post-pandemic era, smartphone usage has surged globally, particularly among young adults. While these devices offer convenience and connectivity, their excessive use has raised concerns about behavioral addiction and psychological well-being. This study investigates the prevalence of problematic smartphone use among young adults in Southern Italy, focusing on usage patterns and socio-demographic correlations. Methods. A cross-sectional survey was conducted between March and June 2025 using an anonymous online questionnaire. The instrument combined ad hoc questions on lifestyle and digital habits with the validated Smartphone Addiction Scale-Short Version (SAS-SV). Participants aged 18-40 were recruited primarily from Sicily and Calabria via university and community networks. Data were analyzed using non-parametric statistical tests and chi-square analysis. Results. The final sample included 451 respondents (average age: 22.42 years), predominantly Italian and non-working students. The SAS-SV identified smartphone addiction in 21.3% of participants, with no significant gender differences. Most users engaged with smartphones for leisure, social media, and entertainment. Significant associations were found between SAS scores and variables such as region, education level, and income. Notably, higher scores correlated with emotional reliance on smartphones and difficulty disengaging from use. Conclusion. Problematic smartphone use affects over one-fifth of young adults in Southern Italy, driven more by app features than screen time alone. These findings underscore the need for targeted public health strategies, including early screening and behavioral interventions, to address digital dependency and promote healthier technology habits in this demographic
