A study from San Diego University indicates that increased cell phone usage among teenagers correlates with lower academic performance and increased feelings of loneliness.
A recent study conducted by the University of San Diego reveals concerning trends regarding cell phone usage among teenagers. The research, led by psychologist Jean Marie Twenge, indicates that countries experiencing the highest increases in adolescent cell phone use also see significant declines in student performance and rising levels of loneliness among youth. This study spans data from over 1.78 million adolescents aged 15 and 16 from over two decades, analyzed through the results of the Programme for International Student Assessment (PISA), which measures educational performance across numerous OECD countries, excluding Brazil.
The PISA assessment not only tests academic competencies in mathematics, language, and science but also gathers information regarding student behavior. By examining these factors, Twenge's research specifically focuses on the relationship between increased screen time, academic outcomes, and students' emotional well-being. Her findings suggest that the more time teenagers spend on their phones, the worse their grades tend to be, while also noting a troubling rise in self-reported feelings of loneliness. This phenomenon prompts further investigation into the long-term implications of smartphone dependency amongst adolescents.
