Study on Teenagers' Use of Mobile Phones

Abstract

In today's society, where almost all teenagers in Korea have access to a mobile phone, numerous studies have demonstrated that mobile phone use leads to symptoms of addiction and hinders academic achievement. This paper investigates whether excessive cell phone use does disrupt teenagers' quality of life, leading to sedentary lifestyles or diminished grades.

To this end, this study conducted a survey on 43 students in regards to their daily smartphone use. A 9-question survey, querying Korean students on their demographics and daily use of smartphones, was shared via email and other messaging platforms. The collected data was analyzed using SPSS and Excel.

Based on the survey, higher-achieving students tend to spend less time on their cell phones overall and more of their screen time is spent on information and news apps. Students with an average level of academic achievement reported a longer average screen time and primarily used social media and entertainment platforms. Among students that reported longer screen times, those with lower grades tended to display signs of addiction more frequently.

This study revealed that longer cell phone use is indeed linked to less physical activity, diminished academic performance, and more evident symptoms of mobile phone addiction.
