We asked both models the same students-focused prompt.
“I need to write a research paper on the impact of social media on teen mental health for my psychology class. Can you help me find recent studies and summarize the key findings with proper citations?”
I need to write a research paper on the impact of social media on teen mental health for my psychology class. Can you help me find recent studies and summarize the key findings with proper citations?
Absolutely. Below is a concise, research-ready overview of recent peer-reviewed evidence on social media and teen mental health, with APA-style citations and a short synthesis you can use as a foundation for your paper.
A note before you use these sources
A major challenge in this literature is that many studies are observational and use self-report measures, so they can show associations but often cannot prove that social media directly causes mental health problems. Also, “social media use” is not one thing: effects differ depending on time spent, type of activity, sleep disruption, social comparison, cyberbullying, and existing vulnerability.
Recent studies and key findings
1) Orben, Przybylski, Blakemore, & Kievit (2022)
Citation (APA 7):
Orben, A., Przybylski, A. K., Blakemore, S.-J., & Kievit, R. A. (2022). Windows of developmental sensitivity to social media. Nature Communications, 13, 1649. https://doi.org/10.1038/s41467-022-29296-3
What they studied:
Large-scale longitudinal data examining whether there are ages when adolescents may be more sensitive to social media use.
Key findings:
- The researchers found evidence for developmental “windows of sensitivity” during adolescence.
- Increased social media use was associated with lower life satisfaction at certain ages, with timing differing somewhat by sex.
- The effects were small, but the pattern suggests adolescence is not a uniform developmental period.
Why it matters:
This study is important because it moves beyond the question of “Is social media bad?” and instead asks when it may matter most.
How you might use it in a paper:
You can argue that social media’s impact may depend on developmental stage, not just overall screen time.
2) Coyne, Rogers, Zurcher, Stockdale, & Booth (2020)
Citation (APA 7):
Coyne, S. M., Rogers, A. A., Zurcher, J. D., Stockdale, L., & Booth, M. (2020). Does time spent using social media impact mental health?: An eight year longitudinal study. Computers in Human Behavior, 104, 106160. https://doi.org/10.1016/j.chb.2019.106160
What they studied:
An 8-year longitudinal study investigating whether time spent on social media predicts later mental health outcomes.
Key findings:
- The study found little evidence that simply spending more time on social media strongly predicts later depression or anxiety over time.
- This challenges the common assumption that more time automatically equals worse mental health.
Why it matters:
It suggests that how teens use social media may matter more than how long they use it.
How you might use it in a paper:
This study is useful as a counterpoint to alarmist claims. It supports a more nuanced argument that quantity of use alone is an incomplete measure.
3) Kelly, Zilanawala, Booker, & Sacker (2018)
Citation (APA 7):
Kelly, Y., Zilanawala, A., Booker, C., & Sacker, A. (2018). Social media use and adolescent mental health: Findings from the UK Millennium Cohort Study. EClinicalMedicine, 6, 59–68. https://doi.org/10.1016/j.eclinm.2018.12.005
What they studied:
A large UK cohort study on social media use and mental health in adolescents.
Key findings:
- Heavy social media use was associated with higher depressive symptoms, especially among girls.
- The link appeared to be partly explained by factors such as online harassment, poor sleep, low self-esteem, and body image concerns.
Why it matters:
This study helps identify mechanisms through which social media may affect mental health.
How you might use it in a paper:
You can cite it to support the argument that the relationship between social media and mental health may be indirect, operating through sleep disruption, cyberbullying, and self-image.
4) Keles, McCrae, & Grealish (2020)
Citation (APA 7):
Keles, B., McCrae, N., & Grealish, A. (2020). A systematic review: The influence of social media on depression, anxiety and psychological distress in adolescents. International Journal of Adolescence and Youth, 25(1), 79–93. https://doi.org/10.1080/02673843.2019.1590851
What they studied:
A systematic review of studies on adolescents, social media, and mental health.
Key findings:
- Across studies, social media use was often associated with depression, anxiety, and psychological distress.
- However, the review also emphasized methodological limitations, including inconsistent measures and difficulty establishing causality.
Why it matters:
This is a strong source for summarizing the broader literature because it synthesizes many studies.
How you might use it in a paper:
Use this review to support a general statement that there is consistent concern in the literature, while also noting that findings are not always straightforward.
5) Valkenburg, Beyens, Pouwels, van Driel, & Keijsers (2022)
Citation (APA 7):
Valkenburg, P. M., Beyens, I., Pouwels, J. L., van Driel, I. I., & Keijsers, L. (2022). Social media use and adolescents’ self-esteem: Heading for a person-specific media effects paradigm. Journal of Communication, 72(1), 56–78. https://doi.org/10.1093/joc/jqab043
What they studied:
This work focuses on how social media affects adolescents differently across individuals.
Key findings:
- Social media effects on self-esteem were not uniform.
- Some adolescents experienced negative effects, some positive effects, and many showed little to no effect.
- Individual differences are crucial in understanding outcomes.
Why it matters:
This study supports a more personalized view of media effects.
How you might use it in a paper:
You can use this source to argue that researchers should move beyond one-size-fits-all conclusions and consider who is using social media, how, and in what context.
6) Odgers & Jensen (2020)
Citation (APA 7):
Odgers, C. L., & Jensen, M. R. (2020). Annual Research Review: Adolescent mental health in the digital age: Facts, fears, and future directions. Journal of Child Psychology and Psychiatry, 61(3), 336–348. https://doi.org/10.1111/jcpp.13190
What they studied:
A major review of evidence on adolescent mental health in the digital age.
Key findings:
- The authors argue that public concern often exceeds the strength of current scientific evidence.
- They conclude that evidence for broad, devastating effects of digital technology on adolescent mental health is mixed and often small in magnitude.
- However, vulnerable youth may face greater risks, especially when digital use involves harassment, social comparison, or sleep disruption.
Why it matters:
This is a high-value review for framing your paper in a balanced way.
How you might use it in a paper:
It’s ideal for an introduction or literature review because it helps you acknowledge both the concerns and the limits of the evidence.

Transformation of adolescent peer relations in the social media context: Part 1—A theoretical framework and application to dyadic peer relationships. Clinical Child and Family Psychology Review, 21(3), 267–294. https://doi.org/10.1007/s10567-018-0261-x
What they studied:
A theoretical and research-based framework for understanding adolescent peer relationships in the social media context.
Key findings:
- Social media intensifies peer processes such as feedback-seeking, social comparison, exclusion, and validation.
- These peer dynamics can influence depression, anxiety, and self-worth, especially during adolescence, when peer approval is highly salient.
Why it matters:
This article helps explain why adolescents are especially sensitive to social media experiences.
How you might use it in a paper:
Use it to build the psychological framework for your argument, especially if your class expects theory as well as data.
8) Abi-Jaoude, Naylor, & Pignatiello (2020)
Citation (APA 7):
Abi-Jaoude, E., Naylor, K. T., & Pignatiello, A. (2020). Smartphones, social media use and youth mental health. CMAJ, 192(6), E136–E141. https://doi.org/10.1503/cmaj.190434
What they studied:
A clinical review discussing youth mental health and social media/smartphone use.
Key findings:
- Social media may contribute to mental health difficulties through cyberbullying, social comparison, poor sleep, and displacement of protective activities.
- The authors also note potential benefits, such as social support, identity exploration, and connection, particularly for marginalized youth.
Why it matters:
This source is useful because it presents both risks and benefits.
How you might use it in a paper:
Use it to show that social media is not purely harmful; it can also provide community and support, depending on the context.
Common themes across the research
Here are the major findings you can synthesize in your paper:
1) The relationship is real, but usually modest
Many studies find a connection between heavy or problematic social media use and depression, anxiety, lower self-esteem, or lower life satisfaction, but the effect sizes are often small.
2) Type of use matters more than total time
Passive scrolling, appearance-based comparison, and emotionally intense engagement may be more harmful than active, supportive communication.
3) Indirect pathways are important
Social media often affects mental health through:
- Sleep disruption
- Cyberbullying or online harassment
- Social comparison
- Body image concerns
- Reduced offline activity
4) Some teens are more vulnerable than others
Effects vary by:
- age and developmental stage
- sex/gender
- preexisting mental health difficulties
- social support
- susceptibility to peer feedback or comparison
5) Social media can also be beneficial
Some adolescents use social media for:
- emotional support
- friendship maintenance
- identity exploration
- access to mental health information
- community, especially for isolated or marginalized youth
Sample thesis statement
Here is a thesis you could adapt:
Although social media can provide adolescents with social connection and support, recent research suggests that its impact on teen mental health is complex: problematic or heavy use is associated with depression, anxiety, and lower self-esteem, but these effects are often indirect and shaped by factors such as sleep disruption, cyberbullying, social comparison, and individual vulnerability.
Sample paragraph you can use or adapt
Recent research suggests that the impact of social media on adolescent mental health is significant but nuanced. Large-scale and review-based studies have found associations between social media use and increased depressive symptoms, anxiety, and psychological distress, particularly among adolescents who experience cyberbullying, poor sleep, or negative social comparison (Kelly et al., 2018; Keles et al., 2020). At the same time, longitudinal evidence indicates that simply spending more time on social media does not always strongly predict poor mental health outcomes, suggesting that the quality and context of use may be more important than total screen time (Coyne et al., 2020). Other research has shown that adolescents may be especially sensitive to social media at certain developmental stages and that effects vary considerably across individuals (Orben et al., 2022; Valkenburg et al., 2022). Overall, the literature indicates that social media is neither uniformly harmful nor harmless; its psychological impact depends on how it is used and by whom.

Detailed Breakdown
For students, the choice between ChatGPT and Perplexity comes down to a fundamental question: do you need a research assistant that always shows its work, or a versatile academic partner that can help with everything from problem sets to essays?
Perplexity is purpose-built for exactly the kind of research students do every day. Every answer comes with cited sources, which means you can verify claims, trace information back to primary materials, and actually use the output to inform real academic work. When you're writing a paper on climate policy or fact-checking a statistic for a presentation, Perplexity's real-time web search and citation model is genuinely useful — not just as a shortcut, but as a research accelerator. Its Spaces feature lets you organize research collections by topic, which suits students juggling multiple courses or a long-term thesis project. The free tier covers basic use cases reasonably well, and the $20/month Pro plan is the same price as ChatGPT Plus.
ChatGPT, by contrast, is the stronger all-rounder. With GPT-5.4 powering the paid tier, it handles a much wider range of student tasks: debugging code for a CS assignment, working through calculus problems step by step, drafting and revising essays, or explaining a dense academic concept in plain language. The canvas feature makes collaborative document editing intuitive, and file uploads mean you can paste in a syllabus or reading and ask targeted questions about it. Voice mode is a practical bonus for reviewing notes hands-free. For STEM students especially, the code execution capability and 77.2% SWE-bench score make it a serious tool for learning and problem-solving.
The trade-off is transparency. ChatGPT doesn't cite sources by default, which means you have to independently verify any factual claims — a real liability when academic integrity is on the line. Perplexity's weakness is the inverse: it's narrower in scope and less capable for generative tasks like writing, coding, or working through multi-step problems.
For most students, the recommendation depends on your primary workflow. If you spend more time researching, writing papers, and need to show credible sourcing, Perplexity is the better daily driver. If your coursework is varied — spanning coding, math, writing, and analysis — ChatGPT's depth and flexibility make it worth the $20/month. Ideally, use both: Perplexity to find and verify information, ChatGPT to help you understand and apply it.
