A specialized iPhone app was used to block internet access, recording any time that the feature was disabled.
In numbers, nearly all the participants — 91 percent — improved on at least one of the three outcomes, while around three-quarters reported better mental health by the end.
The findings even suggest that the intervention had a stronger effect on depression symptoms than antidepressants, and was roughly on par with cognitive behavioral therapy.
What’s driving all this? Ward suggests that the simplest explanation is that the experiment forced participants to spend more time doing fulfilling things in the real world.
Anecdotal, but I can see this. Last year, I took a 2-3 months off of what I now call recreational internet use (e.g. keeping up with the news, forums, etc.), because my mental health and cognitive abilities have deteriorated a lot. The result wasn’t just improved mood but also regaining cognitive skills that I thought I had lost forever. Brain fog also lessened. A year later now, and the improvements are stable and still there, even though I do use the internet recreationally again. It’s still not where I used to be before, but it’s a work-in-progress anyway.
