Screen Time and Sleep Quality in Adolescents

Hard Research Summaries Interpreting Results

In a recent observational study, researchers aimed to understand the correlation between daily screen time and sleep quality among adolescents. They surveyed 500 high school students, collecting data on the average number of hours spent on screens each day, along with self-reported scores on sleep quality, which ranged from 1 (poor) to 5 (excellent).

The study found that students who reported higher daily screen time (defined as more than 4 hours per day) also had lower sleep quality scores, with an average score of 2.3. In contrast, those who used screens for less than 2 hours a day had an average score of 4.1. The researchers also noted that students who engaged in recreational screen time (video games and social media) experienced a more significant decline in sleep quality compared to those whose screen time was predominantly educational.

Based on these findings, which of the following conclusions can be drawn regarding screen time and sleep quality?

There is a direct cause-and-effect relationship between high screen time and poor sleep quality.

Adolescents with less screen time tend to report better sleep quality.

All forms of screen time negatively impact sleep quality equally.

Sleep quality is solely determined by the amount of screen time an adolescent has.
