Study Shows Blaming Instagram And Snapchat For Teen Anxiety May Be Oversimplified
In A Nutshell
Study Size: 25,629 adolescents in Greater Manchester, England | Duration: Three years (2021-2023), starting at age 12
What They Measured: Social media use (including active vs. passive use), gaming frequency, and mental health symptoms
Main Finding: Time spent on social media and gaming didn’t predict which teens would develop anxiety or depression a year later
The Surprise: Among boys with depression, gaming frequency actually decreased (not increased) over time
The Bottom Line: The widely held belief that social media platforms are a major cause of teen mental health problems may be oversimplified
Parents, politicians, and mental health advocates have spent years pointing fingers at Instagram, TikTok, and Snapchat as the primary culprits behind surging rates of teen anxiety and depression. Well, a study tracking more than 25,000 adolescents suggests this widely accepted explanation may be oversimplified.
Researchers at the University of Manchester followed 25,629 teens in Greater Manchester, England, for three years, measuring their social media use, gaming habits, and mental health symptoms annually. The participants started the study around age 12, with roughly equal numbers of boys and girls.
The results? Time spent on social media didn’t predict which kids would become anxious or depressed a year later. Neither did gaming. Even when researchers distinguished between actively posting and passively scrolling, it mostly didn’t change the result.
“The findings of this study do not support the widely held view that adolescent technology use is a major causal factor in their mental health difficulties,” the researchers wrote in the Journal of Public Health.
The Case Against Social Media Looked Solid
The concerns seemed justified. About 22.6% of 11 to 16-year-olds in England currently have a probable mental disorder, especially girls. Some evidence suggests the peak age for these difficulties is around 14.5 years. The timing coincides with the smartphone revolution.
Instagram has faced intense public scrutiny and criticism. Policymakers and advocates have raised concerns about how social platforms might affect teen well-being, with particular attention paid to body image issues. Some states have considered or enacted restrictions on teen access to social platforms.
Some studies found correlations between heavy social media use and mental health symptoms. Teens themselves report feeling worse after certain online experiences. The connection seemed fairly clear.
Of course, correlation isn’t causation. Two events occurring together doesn’t mean one causes the other.
Testing Whether Social Media Actually Causes Depression
Here’s where this study differs from most previous research. Instead of measuring everything at one point in time, study authors tracked the same kids for three years. This allowed them to observe whether an individual teen who increased their social media use would then become more depressed, or whether a teen who decreased their scrolling would get better.
The researchers asked teens how many hours they spent on social media platforms like TikTok, Instagram, and Snapchat during a typical weekday. Those who reported any time then broke it down into active use (chatting, posting) versus passive use (browsing feeds, scrolling). Gaming frequency ranged from “never” to “most days.” Mental health was measured through questions about worry, sadness, and similar feelings.
The key was separating personal quirks from actual changes over time. Some teens might naturally be both anxious and heavy social media users, but that doesn’t mean social media is making them anxious. Maybe anxious kids just gravitate toward these platforms. Or maybe a third factor, like family stress or temperament, drives both.
To find out if social media actually causes mental health problems, changes in a person’s social media use must be tracked to ascertain if those adjustments lead to changes in their mental health. That’s what this study did. In this dataset, that connection didn’t show up.
What Actually Showed Up in the Data
Two findings did emerge, but neither supported the “social media is destroying teens” narrative.
Among girls, those who gamed more in 2022 spent less time on social media by 2023. Among boys, those with more anxiety and depression in 2022 played fewer games by 2023. Both patterns showed up in one gender but not the other.
Neither suggests technology causes mental health problems. The boys finding actually hints at the opposite. Depression typically makes people withdraw from activities they used to enjoy. Alternatively, parents worried about their sons’ mental health may have cracked down on gaming time.
How the Narrative Took Hold
Several factors fueled concern about social media despite limited evidence of causation.
The timing created a compelling story. Smartphones exploded between 2010 and 2012, and teen mental health problems started rising around then. It made sense for countless parents to connect these new devices with an uptick in teenage moodiness.
Most previous studies couldn’t test causation. They measured everything once, used small samples, or failed to separate whether social media use actually caused problems versus just accompanying them. News coverage, meanwhile, amplified individual tragic cases while glossing over the methodological limitations.
The Bigger Picture
If social media isn’t driving teen mental health problems, what is? The study can’t answer that. Possible culprits include academic pressure, economic uncertainty, climate change anxiety, or increased awareness leading to more diagnoses.
The study also can’t rule out short-term effects. If a teen has a brutal day getting cyberbullied, that probably affects their mood immediately. The year-long gaps in this study captured broader patterns, not moment-to-moment impacts.
Different platforms likely have different effects too. Instagram, TikTok, and Snapchat weren’t separated in the analysis. Self-reported hours don’t always match reality.
Still, this study provides some of the most rigorous evidence to date on a question dominating policy debates. Social media use wasn’t a useful clue for predicting who would feel worse a year later. The concern driving proposed regulations and parental restrictions may be aimed at the wrong target.
None of this means parents should completely ignore what their kids do online. That being said, if we want to address rising rates of teen anxiety and depression, we might need to look beyond social media feeds for the real causes.
Paper Notes
Limitations
The study relied on self-reported social media use and gaming rather than objective tracking. The 12-month gaps between measurements couldn’t capture short-term, immediate effects. The research didn’t separate different games or social media platforms. Context like why teens use platforms, their emotional responses, or specific interactions weren’t measured. The sample came from one region in England, which may limit how broadly these findings apply.
