Study of 500,000 Teens Suggests Association Between Excessive Screen Time and Depression (vice.com)

An anonymous reader quotes a report from Motherboard: Depression and suicide rates in teenagers have jumped in the last decade -- doubling between 2007 and 2015 for girls -- and the trend suspiciously coincides with when smartphones became their constant companions. A recent study places their screen time around nine hours per day. Another study, published on Tuesday, suggests that suicide and depression could be connected to the rise of smartphones, and increased screen time. Around 58 percent more girls reported depression symptoms in 2015 than in 2009, and suicide rates rose 65 percent. Smack in the middle of that window of time, smartphones gained market saturation.

In Twenge's new study, published in the journal Clinical Psychological Science, the researchers looked at two samples: a nationally representative survey by ongoing study "Monitoring the Future" out of the University of Michigan, which is administered annually to 8th, 10th, and 12th graders, and the Centers for Disease Control's Youth Risk Behavior Surveillance System, a sample of high school students administered by the CDC every other year. (Both surveys began in 1991.) Altogether, over 500,000 young people were included. The study authors examined trends in how teens used social media, the internet, electronic devices (including gaming systems and tablets), and smartphones, as well as how much time they spent doing non-screen activities like homework, playing sports, or socializing. Comparing these to publicly available data on mental health and suicide for these ages between 2010 and 2017 showed "a clear pattern linking screen activities with higher levels of depressive symptoms/suicide-related outcomes and non-screen activities with lower levels," the researchers wrote in the study. All activities involving screens were associated with higher levels of depression or suicide and suicidal thinking, and activities done away from a screen were not.

      Parents are in a good position to assess the effects at least on Children. You get to talk to a lot of other parents obviously, as well as to experience the behaviour changes.

      1 Affects sleep. They will generally be less able to want to sleep
      2 Affects concentration. They can concentrate for hours on a phone. But I've seen it first hand that anything not as engaging makes them literally sleepy. They won't have the ability to do anything even mildly less "engaging".
      3 Anxiety. Whatever it couases, it can be very strong. You see it with games mostly
      4 Dependency and Withdrawal sympthoms. Removing a phone from a children of any age (1 to 10) triggers agressive behaviour, rage, tantrums, etc.
      5. Confused reality. If the chilren are very young, they have a harder time separating the games from the real world. You see this when game-rules and reality colide. Remember, kids build a model of the world at early stages.
      6. Addictive behaviours. If you know how new studios and app creators work, you'd know that there are psychologists designing the games, the rewards and punishment systems. They literally get to apply scientific research to make the users addicted, and purposefully implement pattners to createanxiety, frustration, pleasure, joy, envy, etc.
      7. Immersion. Most often you see strong identification with game characters or the "online persona" they represent. Basically, it weakens their identification with the real self, and it's replaced by several virtual characters they represent.
      8. Physical detachment of the Ego. We see this in adults too: the person in front of you pays moreattention to what's happeningat the phone than the person in front.
      9. I could continue with other things which would be tied to particular aspects (like social media, etc). But I'll stop at 7.

      All in all, I think the new technologies are awesome, but just like nuclear energy, it brings many dangers. From what I stated, it clearly strongly messes with their mood, anxiety level, attitude, model-building of the world, sleep cycle, social behavior, ability to concentrate, feelings, etc. and withdraws them from the real immediate world we can to live in for millions of years.

      I'd say that they migrate to a virtual world, segmented in apps and fantasy realities of different kinds, made very demanding by the app creators (army of Psy Phd. designing rules based on huge telematics about usage vs unaware children) and making them voluntary slaves to these realities.

      Our society is become more addicted to anything that produces rewards. They are retrating to realities that are more addictive and engaging than the real world around, realities that can dissapear overnight, and where anything can happen to their personas.

      I still haven't figured out how to balance this, except for limiting apps to what I see is more educational and build less anxiety, and limiting the exposure time.

      Back in my days, games where also addictive, and while the scale and sophistication has dramatically changed, and games and social apps have become permanent and "connected", in it's core, it's a similar nature. I remember my old days playing Starcraft for 6 straight hours. It was a nice retreat, and I can't say I noticed the effect other than say that now it has moved towards children starting at age 1 or 2, and has reached penetrated into every wanting children as phones penetration is over 100% now.

      If you want to find out if there is causality between screen time and depression, just follow the breadcrumbs: has the virtual work become a more rewarding place for us than the real world?

      As a parent it's been my experience that if I let my kids have too much screen time, or play too late, their behavior goes down the tubes. My (almost 7 year old) daughter frequently visits a friend's house where they quickly settle in front of a screen of some variety, and she comes back acting like a brat pretty much every time. I'll be talking things over with the other parents next time.

      My son (8.5 years) less so, but there's certain games- like Roblox- that turn him into an insufferable little jerk if I allow any play time.

      So yes, I limit screen time based on my observations of how they behave when I don't limit screen time- and it's not much of a stretch to think this will continue to be true for quite a while, until they learn to self regulate.

      So you can blather on about tropes, and eeeevvvillll stupiiiidd conservatives, but the headline summary lines up with my personal experience, and other parents have similar experiences. Coloring, drawing, reading, playing- none of these activities have the same downsides as screen time.

      Yes, I allow some screen time. As I write this, my daughter is playing minecraft, and my son is watching people on youtube play minecraft. But it's not going to go on all night.

      That only would happen if you're psychologically weak. Let's face it, while life has many awesome things, life is ultimately depressing. We don't appear to be here for any reason. There is no evidence of any objective purpose or even a creator of us or the universe. We are alone, on a tiny rock, floating through a gigantic vacuum of space. We have no evidence that there is anything beyond death and as far as we know, it is the ultimate end. Oblivion.

      Now I think your idea has merit. We are projecting delusion at ourselves. But it's not just from Facebook. Yes, these perfect pictures with tricks and so forth gives a sense of "wow that person is having a magical time". But the problem is far more pervasive. We made up stories about gods, afterlives, we gave ourselves reasons to think we are the center of a universe made for us and shattering the illusion gives rise to a change that manifests initially in sadness.

      What our culture ought to do instead of trying to give children a sense of illusion to evoke false joy is teach them how wonderful and amazing this universe is in a factual way and instill in them the idea that it's a miracle that any of us are here to experience it for the short time we are here.

    So while there does not seem to be a direct argument that there is a causal relationship where "screen time" causes depression, the lie is implicit. First, the "screen time" is called "excessive", i.e. "bad". Then the direly needed warning that correlation is not causation is noticeably absent. To make this worse, it is not called "correlation", but the far less well defined term "association" is used.

    This is just another example manipulative writing. That is indeed bad, because it obscures reality and replaces it by the preconceptions of the author about what must be "bad" (and hence everything must be either proof the author is right or must be ignored).

This suggests that screen time, perhaps especially social media, may have larger effects on adolescent girls’ mental health than on boys’ (and that is indeed what we found, with social media significantly correlated with depressive symptoms only among girls in some analyses and stronger correlations in others). The pattern for males, with increases in suicide deaths but not in depressive symptoms or suicide-related outcomes, suggests that boys’ suicide deaths may be driven by other disorders and risk factors not assessed here."
    So what is really behind this is obsessive gossipping?

Nah, that failed to sound less flippant. I'd insert my anecdotal evidence now, but my n=3 (4 if you count my son) is not going to help much.)
    Aside from that vital information, correlation != causation, but it does point out a possible area for more study in this case.
    Their summation is pretty weak:
    "In conclusion, adolescent mental health issues rose sharply since 2010, especially among females. New media screen time is both associated with mental health issues and increased over this time period. Thus, it seems likely that the concomitant rise of screen time and adolescent depression and suicide is not coincidental."
