What do we really know about the effects of screen time on mental health? | Pete Etchells
A recent report by the Public Health England warns that too much screen time cause emotional problems in children . But is it that simple?
Public Health England announced this week that too much time in front of television screens and computer is causing the increase in psychological problems such as depression and anxiety in children . The report, which can be found here , suggests that the amount of time spent playing computer games was negatively associated with well- being of children - in other words, their mental and physical health , strength and the degree to which they are happy or care about the different aspects of their lives. The effects , particularly in mental health , are more pronounced for children who spent more than four hours a day using some form of screen -based technology.
Although this seems totally dark, there are some caveats that must be taken into account. The report was released to coincide with the Change4Life campaign , not a piece of peer-reviewed , scientific research. In his analysis of screen time , citing data from other reports, for example , Commissioner of the Department of Health , which are themselves secondary analysis of existing data sets , such as the Millennium Cohort Study . If you have read these reports, it is very difficult to have an idea of ??what they did and did not control in the study of the effects of video games or watching television.
But it is interesting to note that the PHE conference begins with a clear overview of the limitations of their research - perhaps the most important is that it is not possible to establish causal relationships of most studies question. In other words , when a study says 'X associated with Y' , which means that " X causes Y " , which is the frequency can interpret. It could also mean " X causes Y ', or perhaps another factor has an effect on both.
So it's a shame when you see titles like The Independent " screen time overload causes depression in children ," the Daily Mail or "TV makes children unhappy " - study no one said anything like that.
- With this in mind , what are the latest scientific evidence in this area look like ? In March, researchers at the Science Unit of Public Health in Glasgow released data also came from the Millennium Cohort Study ( although not mentioned in the PHE Conference ) , who consulted when watching TV or playing video games 5 years was associated with behavioral or psychological problems at age 7. They controlled a large number of factors that could have an impact on its results - things like health , socioeconomic status of the family, the frequency of parent-child activities , and a measure of chaos in the house.
- The results showed that when considering screen time on your own, there was no association between the amount of time spent in a screen and all the problems that consulted - hyperactivity , abnormal behavior, peer relationship problems , and so on . However, these associations disappeared when confounders included almost mentioned. The significant association between the rest went to watch TV for more than three hours a day and conduct disorder.
In its current form , however , research on the long-term effects of screen time is still relatively young, so you still do not know what effect video games , using computers or watching television has on children's development .
With the launch of the campaign Change4Life steering wheel , the PHE is trying to encourage people to adopt a more active lifestyle , changing the car to bike or walk , which limits the display time and operation of healthy snacks for healthier foods . These are all great ideas, but it seems that the best way to stay healthy is to change all these things, not just one. Similarly , we must be careful not to look at the effects of screen time in the isolation of many factors in the wider family environment , which can affect child development behavior.

Gamescom 2013: the six most talked about games so far
Titanfall and Target are two games journalists discuss the chaos in the largest gaming event in the world
Gamescom is crazy. Several full of video games giant rooms , besieged by 200,000 people, all vying for the practice time - and the booty . While E3 is generally considered the largest industry event , the giant based in Cologne is the truth, the public face of the epicenter game of the year .
walk in the grand spectacle of the plant, I was talking to journalists and developers, ask questions about what they saw and what they wanted to see. Of course, there are many jewelry and low profile indie treasures can be found here , but these are the titles of almost everyone spoke . They may not be the
best games Gamescom , but those who have been raised repeatedly over the past four days. Besides the giant hardened waiting three hours files , cheese pretzels, cos -play and endless noise son , these are the things inside talking about ...
Titanfall (EA, One Xbox , Xbox 360, PC )
look , okay, it's just a sci-fi shooter and is not exactly pushing the boundaries of game design innovation. However, the addition of a double jump rocket, the ability to run along walls , and of course the staff, including mechs Titan add to experience exciting and frantic FPS . Oh, and the application of the mechanical history of the multiplayer experience is very cleverly handled. I love the epilogue sequence at the end of each game. In this case, the losing party in a team-based confrontation must quickly escape a dropship, while trying to pick the winner of all runners . If one of the losers are , get bonus XP, absorb the shock of defeat. Looks like a little more, but it's fun.
shows Dogs (Ubisoft , PS3, PS4 , Xbox 360, Xbox One, PC , Wii U)
After their explosive debut at E3 in 2012, piracy cyberpunk thriller was forgotten for a while. Some began to wonder if it was a generic science - fiction festival lies in convincing the idea of ??a character that can be entered into the smart phones and the infrastructure of the city. But the playable demo at Gamescom demo reveals fascinating asymmetric multiplayer mode that arises in the single player campaign , allowing participants paired randomly to participate in the style of cat and mouse face- offs. A player must mingle with the crowd , trying to get close enough to cut the PDA of your opponent, while the mouse is escaping. Ubisoft showed the companion app , allowing tablet owners to play the game of another player as a police helicopter . While console gamers is to escape from a car, the participant tablet directs police vehicles to its picturesque location with items such as drawbridges and traffic bollards to stop . Smart things .
- destination ( Activision , PS3, PS4 , Xbox 360, Xbox One)
- Bungie is still quite shy about their gorgeous ambitious MMO shooter that takes place in a future version of our solar system. The Gamescom trailer shows some new small pieces Videos - A Brain -apocalyptic full of rusty cars on an exotic landscape of shades of pink , lots of combat. Apart from this , we hear more about how public events nest perfectly in solo and co -op campaigns , allowing players to collide with the objectives of other groups , united in the task of acquiring additional experience . But how these events are mixed with raids, strikes and campaign missions , we're not quite sure . Everything looks so beautiful, and the idea of ??bringing other squads of soldiers involved in their private wars is strangely compelling.
Everyone was very low on this at E3, where shots available seem to suggest the installation much more courageous and more standardized serial adventure zombie. But the Cologne demonstration went well , including the intelligent integration of glass that allows players to Xbox One for your phone in the game so that the missions and objectives are effectively delivered through phone calls . You have a game to call and say your leg zombie-infested building, this is the future.
