Screentime and Social Media: psychological aspects and addiction

Online activities involving prolonged screen time and the use of social media are widespread. Along with the opportunities and positive consequences associated with social media, the prevalence of problematic and addictive use is increasing.

This is illustrated through the use of a theoretical model. Finally, challenges and opportunities for prevention and treatment are outlined.
