What Your Smartphone Knows That Your Mother Doesn’t
Can Your Smartphone Be Used to Detect Depression?
It’s always there, in your pocket or purse or on your desk, quietly collecting information. And apparently, when it comes to depression, there’s quite a lot your smartphone knows about you.
According to a small study from Northwestern Medicine, that data from your smartphone can predict with eerie 87 percent accuracy whether you’re suffering from depression or not.
The telling signs: You spend more time on your smartphone and less time leaving the house, and you visit very few places each day.

The researchers used Craigslist to find 40 test subjects between the ages of 19 and 58, and outfitted their smartphones with an app to monitor their location and usage. The individuals took a questionnaire that measured signs of depression; half of the subjects had troubling symptoms and half did not. Using GPS, the phones tracked the subjects’ movements and locations every five minutes. The subjects also were asked questions about their mood at different points during the day.
These factors were then correlated with the test subjects’ original depression test scores. And the results were uncanny. Depressed people used their phones more often and for longer periods of time —an average of 68 minutes a day. By comparison, the individuals who didn’t show signs of depression spent only 17 minutes on theirs. Researchers attributed the increased use of the phone to task avoidance, another symptom of depressed people.
Perhaps more significant than the findings of this small study — only 28 of the 40 subjects had enough data to be studied — is the potential the researchers felt that smartphones could play in future medical diagnosis.
When loaded up with the correct sensors, the smartphone can be used to detect a person’s emotional states, and monitor moods, without the user having to utter a word. It also has the ability to offer suggestions to reinforce positive behaviors when depression is detected. The results of the study were published in the Journal of Medical Internet Research yesterday, but one conclusion was becoming increasingly evident even before the report came out: Smartphones — and the sensors they now contain — just keep getting smarter.
Coming Soon: Deductible Relief Day!
You may be familiar with the concept of Tax Freedom Day – the date on which you have earned enough to pay all of your taxes for the year. Focusing on a different kind of financial burden, analysts at the Kaiser Family Foundation have created Deductible Relief Day – the date on which people in employer-sponsored insurance plans have spent enough on health care to meet the average annual deductible.
Average deductibles have more than tripled over the last decade, forcing people to spend more out of pocket each year. As a result, Deductible Relief Day is “getting later and later in the year,” Kaiser’s Larry Levitt said in a tweet Thursday.
Chart of the Day: Families Still Struggling
Ten years into what will soon be the longest economic expansion in U.S. history, 40% of families say they are still struggling, according to a new report from the Urban Institute. “Nearly 4 in 10 nonelderly adults reported that in 2018, their families experienced material hardship—defined as trouble paying or being unable to pay for housing, utilities, food, or medical care at some point during the year—which was not significantly different from the share reporting these difficulties for the previous year,” the report says. “Among adults in families with incomes below twice the federal poverty level (FPL), over 60 percent reported at least one type of material hardship in 2018.”
Chart of the Day: Pragmatism on a Public Option
A recent Morning Consult poll 3,073 U.S. adults who say they support Medicare for All shows that they are just as likely to back a public option that would allow Americans to buy into Medicare or Medicaid without eliminating private health insurance. “The data suggests that, in spite of the fervor for expanding health coverage, a majority of Medicare for All supporters, like all Americans, are leaning into their pragmatism in response to the current political climate — one which has left many skeptical that Capitol Hill can jolt into action on an ambitious proposal like Medicare for All quickly enough to wrangle the soaring costs of health care,” Morning Consult said.

The Earned Income Tax Credit, a refundable tax credit for low- to moderate-income workers, was established in 1975, with nominal claims of about $1.2 billion ($5.6 billion in 2016 dollars) in its first year. According to the Tax Policy Center, by 2016 “the total was $66.7 billion, almost 12 times larger in real terms.”
Chart of the Day: The Big Picture on Health Care Costs
“The health care services that rack up the highest out-of-pocket costs for patients aren't the same ones that cost the most to the health care system overall,” says Axios’s Caitlin Owens. That may distort our view of how the system works and how best to fix it. For example, Americans spend more out-of-pocket on dental services ($53 billion) than they do on hospital care ($34 billion), but the latter is a much larger part of national health care spending as a whole.
