Plain English Summary

Summary written for general audiences

The cross-sectional study included 2,785 high school students in Niigata, Japan. Mean mobile phone use was 24 hours per week with a median of 18 hours. Longer mobile phone use was associated with female students, no sports club participation, early mobile phone use, and fewer hours of sleep. Overall associations between hours of mobile phone use and mood scores were significant for depressed mood, tension and excitement, and fatigue.

Why This Matters

The study aimed to clarify associations between duration of mobile phone use and psychological mood in high school students. Psychological mood was measured with the Mood Inventory, which has five subscales scored from 8 to 32, with higher scores indicating stronger feelings.
