It was interesting to read an article in the Wall Street Journal (Tuesday 14 September 2021) reporting that Facebook is aware of the psychological dangers Instagram poses to teenagers, especially girls. The creators of Instagram leaked an internal slide acknowledging they make body image issues worse for one in three teenage girls. The statistics in this slide were not surprising to me; this research topic is one that St Andrew’s College has followed with keen interest for many years.

What does the research say?

In her 2017 book iGen: Why Today's Super-Connected Kids Are Growing Up Less Rebellious, More Tolerant, Less Happy, Jean Twenge explored the impact smartphones were having on young people. Since then, Professor Twenge and Professor Johnathan Haidt (Author of Coddling of the American Mind) have closely followed correlational experiments and longitudinal studies to investigate the association between screen time, social media use, and negative mental health outcomes.

Several studies show an association between heavy social media usage and adverse mental health outcomes. Still, there are some essential qualifications that parents and educators should understand:

On screen time

• Researchers from Oxford and Cardiff Universities proposed a 'Goldilocks Theory.' After studying 120,000 15-year-olds, they found a point between low and high usage of technology that is 'just right' for teenager's well-being. They attributed this to the ability of digital connectivity to enhance creativity and communication skills. Overall, the evidence indicated that moderate use of digital technology is not intrinsically harmful and may be advantageous in a connected world (Przybylski & Weinstein, 2017). They suggest that 15 years olds should spend no more than 1 hour and 57 minutes on a smartphone on a weekday. The authors felt any more than this could interfere with socialising, exercise, school work or sleep. 
  
  
• Interestingly, studies show little evidence that 'screen time' (including computers, video games, and television) has a direct association with negative mental health outcomes (Orben & Pryzybylksi, 2019).

On Social Media

• Several robust studies have shown an association between heavy social media use and depression. However, the associations are curvilinear, meaning that the harmful impacts of social media only become clear with heavy usage (more than 4 hours per day) (Twenge & Campbell, 2019).
  
  
• In studies that offer a comparison between male's and female's social media usage, harm is significantly larger for females (Booker, Kelly, and Sacker, 2018).

• In a UK study of 10,000 young people, researchers found social media impacts to be nuanced. High social media use often leads to experiences of cyberbullying, sleeping for less than 8 hours a night, and lack of exercise. These were all correlated with adverse mental health impacts. Furthermore, the mental health impacts of these factors were more pronounced with girls (Kelly, Zilanawala, Booker & Sacker, 2018).
  
  
• Of the ten true experiments published since 2015 that used random assignment, seven of them found that reducing or eliminating social media time caused improvements in variables related to mental health, but not necessarily on all measures (Haidt & Twenge, 2021).
  
  
• Most research focuses on adolescents above the age of 14. Researchers like Twenge and Haidt strongly suggest pre-teens should not access social media platforms like Instagram. For example, Booker, Kelly, and Sacker (2018) studied 10,000 10–15 year olds in the UK and concluded that social media interaction at ten years of age was associated with declines in well-being for females.

The message, is that it is not social media, per se, that causes harm. It's about getting the balance between social media use and other age-appropriate activities and ensuring that there aren't specific negative things happening online.

Why is social media use so concerning for our girls?

As far as the research is concerned, one thing is clear; girls are more negatively impacted by social media use than boys. There are several reasons attributed to this finding. First, studies with large sample sizes provide evidence that girls use social media more than boys. They also use it differently. Girls more frequently use Snapchat and Instagram, whereas many boys tend to use YouTube. A completely visual interface, Instagram provides a platform for people to share filtered and edited photos prompting young people to compare their own lives to the idealised images of the online world. We need to remember that adolescence is already a time where teenager's construction of identity is initiated by pubertal, neurological and cognitive transformations that influence an increased social awareness. Scrolling through unrealistic and carefully curated photos can trigger negative upward social comparisons, self-consciousness and an unhealthy pursuit for perfectionism. Sadly, research shows this also leads to body image concerns for young people, especially our girls.

Interestingly, research suggests that girls are more than three times more likely to be cyberbullied than boys. Scholars do not articulate the reasons for this, but suggestions do include the difference in social media platforms used between girls and boys, more time spent on social media, and the extent that girls are more verbal. Cyberbullying and online harassment can include the sharing of harmful, threatening, or false content. It can also be associated with intentional exclusion. Cyberbullying has a proven significant impact on young people's mental health as it can be persistent and permanent. Research says cyberbullying is particularly prevalent in middle school years (Years 13-15).

At St Andrew’s, we continue to monitor research about technology's positive and negative impacts on our young people. The research says high social media use is a concern, especially for girls, and especially before they reach high school. However, findings are often nuanced and multi-causal, so they require critical analysis. In my next blog post, I will discuss the proactive strategies St Andrew’s College has employed in response to the research findings. As you can imagine, schools are only one small part of the puzzle; parents play a crucial role in mediating and restricting social media use. I look forward to sharing our recommendations about this too.
