Smartphone sensors may detect depression, study says - IceWizard - 07-17-2015
Data from your smartphone sensors tracking phone usage and geographical locations may be able to detect depression, revealed a study published Wednesday in the Journal of Medical Internet Research.
Study participants who were depressed used their phones for an average of 68 minutes a day, compared to 17 minutes for non-depressed individuals.
Spending more time at home and in fewer locations was also linked to depression.
According to phone sensor data, researchers identified individuals with depressive symptoms with 87 percent accuracy.
Researchers used GPS tracking and phone data to study a group of 28 individuals with an average age of 29 over two weeks.
At the beginning of the study, the 20 female
and eight male participants took a widely
used standardized questionnaire measuring depression, the PHQ-9.
Within the group, 14 participants did not have any signs of depression, and the remaining half had symptoms ranging from mild to severe depression.
Typically, smartphone applications for mental health treatment are essentially feedback tools, requiring users to enter information, said senior author David Mohr, director of the Center for Behavioral Intervention Technologies at Northwestern University Feinberg School of Medicine.
The team proposed using a phone’s existing sensors to detect symptoms to potentially lead to timelier, more effective care.
“People get tired very quickly of entering
information in [apps],†Mohr told FoxNews.com. “There are so many sensors
available in smartphones; harnessing them
could passively detect the state we’re
interested in.â€
The team used 12 variables like GPS and
phone usage data, and correlated algorithms with the participants’ PHQ-9 test results. They found that a number of them significantly corresponded with depression.
“One of the most significant variables was
actually how subjects spent time in different
locations they were visiting— spending most of their time in still locations or spreading time across different locations,†lead author Sohrob Saeb, a postdoctoral fellow and computer scientist in preventive medicine at Feinberg told FoxNews.com.
“It was very much related to depression; people with higher depressive symptoms
seemed to spend most of the time in very
few locations.â€

Ms. Hepburn , please don't shoot the messinger .. I just saw this story and posted it ..
You do, however, bring many valid points to light ..
Hard for them to do a complete "study" based on such little data ...

this does not take into account things such as those whom r homebound from a sudden accident. leads to depression and being on phone more.
or, birthdays and holidays, one will be on more.
but, never fear. within a month to a year, another, more expensive study will come out with exact opposite results.
i see this a lot.
another person trying to make a name for himself will publish the opposite. or a more extreme study.
but, no doubt about it, the gvt works with companies (as they did with AT&T to tap our phones and email conversations,) to know whatever they can about us.
they want to segregate the disabled, the depressed, those not able to work or perform. we are useless to them.
and, where do all these signals of depression go to? what agency? (in future.)
further, hell, of course we are all depressed to some degree. we are still in a depression no matter what the gvt says.
Fox News on cable was great after 9/11. But, now, its all fluff.
Not shooting messenger.
(its just that mothers, in particular, have been told to lie the newborn baby on his tummy to prevent SIDS. then, on his back. then, u roll up a swaddling blanket and keep him on his side. now, its back to on his tummy.
i am waiting till they say hang that baby from the chandellier.)
good work, Ice.
But, for every study saying one thing, another will pop up saying the exact opposite. IMHO and all.

GEEZZZZ! Is there anything they don't try to find out about us? Will the next new device be able to tell if you made a crap that day? Where will this intrusion into our lives ever end?

it won't.
its getting worse. sighs.
