A recent study published in the journal Adolescents has revealed significant connections between nighttime phone use, exposure to cyberbullying, and adverse effects on sleep and mental health in Australian children aged 7 to 19 years.
Key Findings
The study, conducted by researchers exploring the impact of nighttime phone use and cyberbullying on children’s psychological well-being and sleep, found that these factors were independently associated with poor sleep quality and increased psychological distress. The study also examined whether nighttime phone use exacerbated the effects of cyberbullying on sleep and mental health, with particular attention to differences in gender and age.
Background
Extensive research has established a clear link between the use of digital devices at night and sleep-related issues, such as delayed sleep onset and reduced sleep duration. Adolescents, in particular, are prone to nighttime phone use, driven by social media engagement and texting beyond bedtime.
The study underscores the dual threat posed by nighttime phone use and cyberbullying. Cyberbullying, which includes harmful behaviors like cyberstalking, online harassment, and doxing, has been shown to significantly affect children’s psychological well-being, leading to mental health challenges. Nighttime phone use allows cyberbullying to continue into the night, further disrupting sleep and exacerbating psychological distress.
Study Overview
Using a cross-sectional design, the researchers analyzed archival data from the Resilient Youth Australia survey, which included participants from 918 schools across the country. The survey encompassed students aged 7 to 19 years from diverse socioeconomic backgrounds, attending both private and public schools.
The survey assessed psychological distress using a validated patient health questionnaire designed to measure anxiety and depression. Additionally, students reported the frequency of nighttime phone use, sleep duration, and exposure to cyberbullying. The frequency of nighttime phone use ranged from never to more than five times a week, while sleep duration was categorized based on adherence to the recommended eight hours of sleep per night. Cyberbullying frequency was measured from never to at least once in the previous school term. The data collection was conducted online during class time, with strict measures to ensure anonymity and confidentiality.
Results
The findings revealed that nighttime phone use was prevalent among students, particularly in secondary schools, with over 60% of students reporting phone use at least once a week during the night. Cyberbullying was also common, with 15% of students reporting having experienced it in the previous term. Notably, cyberbullying was more frequent among boys in primary school and among girls in secondary school.
Students who were victims of cyberbullying were more likely to engage in nighttime phone use, which in turn was associated with poorer sleep outcomes and increased psychological distress. A substantial number of students did not achieve the recommended sleep duration, with one-fourth of primary school children and 40% of secondary school students, particularly girls, reporting insufficient sleep.
The study also found that girls in secondary schools reported higher levels of psychological distress, with gender differences becoming more pronounced during adolescence. Regardless of age or gender, cyberbullying victims consistently reported greater psychological distress and sleep deficits.
Importantly, the study highlighted that nighttime phone use exacerbated the negative impact of cyberbullying on sleep across all age groups and genders. However, the effect of nighttime phone use on the relationship between cyberbullying and psychological distress was more pronounced among boys in secondary school.

The research underscores the need to regulate children’s use of digital devices at night to protect their psychological well-being and ensure sufficient sleep. The study calls for further research into the effects of cyberbullying during nighttime phone use, emphasizing the importance of targeted interventions to mitigate the harmful consequences of these behaviors.
