In the post-COVID-19 era, adolescent internet addiction has emerged as a significant public health challenge, impacting psychological well-being globally. A recent large-scale study involving over 8,000 junior high school students in China highlights a troubling link between compulsive digital use and mental health problems. Researchers found that nearly one in five students met the criteria for addiction. Consequently, this addiction was significantly correlated with elevated levels of depression, anxiety, and stress.

Clinical Impact of Adolescent Internet Addiction

The study utilized propensity score matching (PSM) to ensure the accuracy of its findings. By comparing addicted students with a matched control group, researchers identified a clear average treatment effect (ATT). Specifically, addicted adolescents showed markedly higher scores for psychological distress across all matching methods. Furthermore, the persistence of social isolation and increased screen time from the pandemic era appears to have normalized these problematic behaviors. These findings suggest that adolescent internet addiction acts as a potent risk factor for worsening mental health outcomes in the current era.

Clinicians must recognize that digital dependency is often comorbid with other psychiatric conditions. For instance, recent systematic reviews suggest that Cognitive Behavioral Therapy (CBT) and family-based interventions are highly effective. These treatments help teenagers regain control over their digital habits while addressing underlying emotional drivers. Moreover, early screening in school environments and pediatric clinics is essential. Consequently, healthcare providers should prioritize identifying these patterns early to prevent long-term mental health decline.
