Researchers predicted if somebody was depressed, by collected mobile phone data, with 87% accuracy.
28 adult participants carried a mobile phone with the sensor data acquisition app for 2 weeks.
App detects depression by tracking the duration of daily use of phone and daily geolocation of the owner.
The more time a person spends using a mobile phone, the more likely they’re depressed.
Average daily mobile phone use for depressed people was 68 minutes, for non-depressed people - 17 minutes.
Spending most of their time at home, or in fewer locations were linked to depression.
Smart-phone data was better at detecting depression than daily questionnaires.
