Screen Time and Sleep: Survey Study of Teenagers
This research paper investigates the relationship between screen time and sleep time among high school students aged 14–18. Drawing on prior literature, the study hypothesized that increased screen time would correlate with decreased sleep duration. A paper survey with eight questions was administered to fifteen students, followed by brief face-to-face interviews with four participants. Results confirmed a negative correlation between screen time and sleep time, with smartphones and social media identified as primary drivers of extended nightly screen use. The paper discusses themes of procrastination, homework, and entertainment as contributing factors, and suggests future research should examine the relationship between social media engagement and academic performance among teenagers.

What makes this paper effective
- The paper clearly states a testable hypothesis at the outset and consistently returns to it across all sections, giving the argument coherence from introduction to conclusion.
- It combines quantitative survey data with qualitative face-to-face interviews, allowing numerical findings to be enriched by participant-level context and anecdote.
- The introduction grounds the study in two peer-reviewed sources before any data is collected, demonstrating that the hypothesis is evidence-informed rather than speculative.
Key academic technique demonstrated
The paper demonstrates triangulation — using multiple data collection methods (written survey and brief interview) to cross-validate findings. The interview themes directly extend and explain patterns observed in the survey data, showing how mixed-methods approaches can strengthen a small-sample study's credibility.
Structure breakdown
The paper follows a conventional IMRaD structure: an Introduction that reviews prior literature and states the hypothesis; a Method section explaining sampling, survey design, and interview procedures; a Results section summarizing quantitative and qualitative findings; a Discussion section organized around three interview themes; and a Conclusion that restates findings and points toward future research directions. An Appendix provides the survey instrument and raw response data.
Introduction
This research paper explores the possible effects of screen time on sleep, based on experiences reported by participants in a survey. Prior to conducting the survey, the hypothesis was: more screen time equals less sleep time. Surveys are a valid research method for testing hypotheses by collecting responses from target populations. By asking whether screen time — including video games, computers, mobile devices, and television — affected the sleep outcomes of teenagers aged 14–18, the study sought to discover a negative correlation between screen time and sleep time. The results supported the hypothesis that teenagers exposed to higher levels of screen time sleep fewer hours.
Teenagers have access to a wide array of electronics. From televisions to smartphones to computers, today's youth are exposed to a host of devices that emit artificial light, which may affect how much sleep they get. This research paper explores the possible connection between screen time and sleep time. Specifically, the aim is to test the hypothesis: does increased screen time have a negative effect on sleep time? A multi-question survey was used to determine any possible effects screen time may have on the sleep duration of high school-aged teenagers.
The hypothesis was developed from several key studies examining the effects of screen time on sleep. One study conducted a systematic literature review on 67 studies published between 1999 and early 2014, finding that "screen time is adversely associated with sleep outcomes (primarily shortened duration and delayed timing) in 90% of studies" (Hale & Guan, 2015, p. 50). The results suggest that increased screen time negatively affects sleep by decreasing both sleep length and time spent in deep sleep. The study also identified a possible secondary negative effect: overall well-being. The authors advised that "youth should be advised to limit or reduce screen time exposure, especially before or during bedtime hours to minimize any harmful effects of screen time on sleep and well-being" (Hale & Guan, 2015, p. 50). Because insufficient sleep can lead to a negative impact on a person's well-being, reducing screen time before sleep is particularly important.
The survey was structured around a 2013 study on presleep activities, which found that "presleep activities have been implicated in the declining sleep duration of young people. The top 20 activities were grouped into 3 behavioral sets: screen sedentary time, nonscreen sedentary time, and self-care" (Foley et al., 2013, p. X9). These three behavioral sets formed the basis of the survey and guided the type of questions posed to participants. The study's findings were consistent with prior literature: increased screen time led to decreased sleep time.
The study also remarked on sleep onset timing and its relationship to the degree of screen time. "Television watching was the most commonly reported activity, and screen sedentary time accounted for approximately 30 minutes of the 90-minute presleep period. Participants with a later sleep onset had significantly greater engagement in screen time than those with an earlier sleep onset" (Foley et al., 2013, p. X9). Based on this, the survey included questions about how sleepy participants felt before going to bed, in order to capture the correlation between later sleep onset and screen sedentary time. As Foley et al. (2013, p. X9) concluded, "screen sedentary time dominated the presleep period in this sample and was associated with a later sleep onset. The development of interventions to reduce screen-based behaviors in the presleep period may promote earlier sleep onset and ultimately improved sleep duration."
