It’s an often repeated claim, but it seems hard to proof: our smartphones seem not to be the reason some of our children feel worse.

From the press release:

A new study, published in the journal Clinical Psychological Science, suggests that the time adolescents are spending on their phones and online is not that bad.

The study tracked young adolescents on their smartphones to test whether more time spent using digital technology was linked to worse mental health outcomes. The researchers — Candice Odgers, professor of psychological science at the University of California, Irvine; Michaeline Jensen, assistant professor of psychology at the University of North Carolina at Greensboro; Madeleine George, postdoctoral researcher at Purdue University; and Michael Russell, assistant professor of behavioral health at Pennsylvania State University — found little evidence of longitudinal or daily linkages between digital technology use and adolescent mental health.

“It may be time for adults to stop arguing over whether smartphones and social media are good or bad for teens’ mental health and start figuring out ways to best support them in both their offline and online lives,” Odgers said.

“Contrary to the common belief that smartphones and social media are damaging adolescents’ mental health, we don’t see much support for the idea that time spent on phones and online is associated with increased risk for mental health problems,” Jensen said.

The study surveyed more than 2,000 youth and then intensively tracked a subsample of nearly 400 teens on their smartphones multiple times a day for two weeks. Adolescents in the study were between 10 and 15 years old and represented the economically and racially diverse population of youth attending North Carolina public schools.

The researchers collected reports of mental health symptoms from the adolescents three times a day and they also reported on their daily technology usage each night. They asked whether youth who engaged more with digital technologies were more likely to experience later mental health symptoms and whether days that adolescents spent more time using digital technology for a wide range of purposes were also days when mental health problems were more common. In both cases, increased digital technology use was not related to worse mental health.

When associations were observed, they were small and in the opposite direction that would be expected given all of the recent concerns about digital technology damaging adolescents’ mental health. For instance, teens who reported sending more text messages over the study period actually reported feeling better (less depressed) than teens who were less frequent texters.

Abstract of the study:

This study examines whether 388 adolescents’ digital technology use is associated with mental-health symptoms during early adolescence to midadolescence. Adolescents completed an initial Time 1 (T1) assessment in 2015, followed by a 14-day ecological momentary assessment (EMA) via mobile phone in 2016–2017 that yielded 13,017 total observations over 5,270 study days. Adolescents’ T1 technology use did not predict later mental-health symptoms. Adolescents’ reported mental health was also not worse on days when they reported spending more versus less time on technology. Little was found to support daily quadratic associations (whereby adolescent mental health was worse on days with little or excessive use). Adolescents at higher risk for mental-health problems also exhibited no signs of increased risk for mental-health problems on higher technology use days. Findings from this EMA study do not support the narrative that young adolescents’ digital technology usage is associated with elevated mental-health symptoms.
