Could the devices being blamed for teen depression be useful in revealing it?
Studies have linked heavy smartphone use with worsening teen mental health. But as teens spend time on sites like Instagram, Snapchat and YouTube, they also leave digital trails that may offer signs about their mental well-being.
Experts say possible warning signs include changes in writing speed, voice quality, word choice and how often a student stays home from school.
There are more than 1,000 smartphone "biomarkers," said Dr. Thomas Insel, former head of the National Institute of Mental Health, which is the largest mental health research organization in the world. Insel is a leader in the smartphone psychiatry movement.
Researchers are testing smartphone apps that use artificial intelligence, or AI, to predict depression and possible self-harm. Using smartphones as mental health detectors require permission from users to download an app, and permission could be revoked any time.
Nick Allen, a psychologist at the University of Oregon, has created an app being tested on young people who have attempted suicide. Allen says the biggest barrier is discerning the mental health crisis signals in the information on people's phones.
Suicide is the second leading cause of death for people between the ages of 10 and 34 in the United States. By 2015, suicide rates among teen boys rose to 14 in every 100,000 and five in every 100,000 people, among girls. A recent study suggested a rise in smartphone use has probably worsened the crisis.
People with mental illness, Insel said, usually get treatment "when they're in crisis and very late. ... We want to have a method to identify the earliest signs."
If smartphones can become effective predictors, app developers say the goal might be to offer automated text messages and links to assistance, or digital messages to parents, doctors and first responders.
Facebook employs "proactive detection." Last year, after a suicide was broadcast on Facebook Live, the company trained its AI systems to look for words in online posts that could predict possible self-harm. Friends' comments expressing concern about the user's well-being are part of that detection system.
Facebook has helped first responders quickly reach around 3,500 people in the past year. But the company did not offer followup details on those people.
Ongoing research includes a Stanford University study of about 200 teens. Many of them are at risk for depression because of bullying, family issues or other problems. Teens who have been studied since grade school get an experimental phone app that asks them questions about their mood three times a day for two weeks.
Laurel Foster, 15, is part of the study. Foster said she is stressed about school and friendships. Depression is common at her San Francisco high school, she said. The smartphone app felt a little like being spied on, she said, but many websites are already following users' behaviors.
Alyssa Lizarraga, 19, is also part of the study. Lizarraga said she has had depression since high school, and worries about her heavy use of smartphones and social media. She said comparing herself with others online sometimes causes her sadness. But she believes using smartphones to identify mental health problems might help push people to seek early treatment.
At the University of California, Los Angeles, researchers offer online counseling and an experimental phone app to students who show signs of at least minor depression on a test. It is part of a larger effort launched in 2017 by the university to battle depression in its students. About 250 UCLA students agreed to use the app during their first year.
At the University of Illinois' Chicago campus, researchers are using crowdsourcing to test their experimental phone app. Nearly 2,000 people have downloaded the app and agreed to let researchers follow typing behaviors. Alex Leow, a professor of psychiatry and bioengineering at the university, helped develop the app.
The study is for people 18 and older, but Leow said it could also be used for children if successful.
Along with studies at universities, technology companies such as Mindstrong and Verily — the tech health division of Google — are testing their own experimental apps.

Economics, tensions blamed for Chinese students shifting from US to Australia, Britain
![FILE - Chinese students wait outside the U.S. Embassy for their visa application interviews, May 2, 2012, in Beijing.](https://gdb.voanews.com/01000000-0aff-0242-4fea-08dc96d3d82c_cx0_cy5_cw0_w250_r1_s.jpg)
U.S. universities are welcoming international students as the academic year begins. But while the total number of foreign students is steadily growing, the top sending country, China, is showing signs of leveling out or shrinking.
Industry analysts say the negative trend is mainly due to higher costs amid China’s struggling economy, with a growing number of students going to less expensive countries like Australia and Britain, and tense ties between Washington and Beijing.
The number of foreign students studying in the U.S. in 2022-23 passed 1 million for the first time since the COVID pandemic, said Open Doors, an information resource on international students and scholars.
While the U.S. saw a nearly 12% total increase year-on-year for that period, the number of international students from China, its top source, fell by 0.2% to 289,526.
That’s 600 fewer students than the 2021-22 academic year, when their numbers dropped by nearly 9%. The COVID pandemic saw Chinese student numbers drop in 2020-21 by nearly 15%, in line with the world total drop.
While it’s not yet clear if the drop is a leveling out or a fluctuating decline, analysts say China’s struggling economy and the high cost of studying in the U.S. are the main reasons for the fall in student numbers.
Vincent Chen, a Chinese study abroad consultant based in Shanghai, said although most of his clients are still interested in studying in the U.S., there is a clear downward trend, while applicants for Anglophone universities in Australia and Britain have been increasing.
"If you just want to go abroad, a one-year master's degree in the U.K. is much cheaper,” Chen said. “Many people can't afford to study in the U.S., so they have to settle for the next best thing."
Data from the nonprofit U.S. group College Board Research shows that in the 2023-24 academic year, the average tuition and fees for a U.S. private college four-year education increased 4% to $41,540 compared with the previous academic year.
The British Council said three to four years of undergraduate tuition in Britain starts as low as $15,000.
The number of Chinese students in Britain was 154,260 in 2022-23, according to the U.K. Higher Education Statistics Agency, HESA, up from 121,145 in the 2018/19 academic year.
Australia’s Home Affairs office said in the 2023-24 program year, China was the top source foreign country for new student visa grants at 43,389, up slightly (1.5%) from the previous year.
Chen said Chinese state media's negative portrayal of the United States and concerns about discrimination have also contributed to the shift.
Bruce Zhang, a Chinese citizen who received his master's degree in Europe after studying in China, told VOA Mandarin he had such an incident occur to him after he was admitted to a U.S. university’s Ph.D. program.
When he entered Boston's Logan International Airport last year, Zhang said customs officers questioned him for more than an hour about his research, and if it had any links to the military, and took his computer and mobile phone for examination.
"Fortunately, I had heard that U.S. customs might be stringent in inspecting Chinese students, so I had relatively few study-related data and documents on my personal computer," he said.
Zhang was allowed to enter the U.S. for his studies in materials science, but the questioning left him so rattled that he has encouraged other Chinese to study elsewhere.
Cui Kai, a study abroad consultant in Massachusetts told VOA Mandarin that experiences like Zhang’s or worse happen for a reason.
"Students who were questioned or their visas were revoked at the customs are usually those who completed their undergraduate studies in China and come to the U.S. for a master's or doctoral degree in a sensitive major," said Cui.
Former President Donald Trump signed Proclamation 10043 in June 2020, prohibiting visas for any Chinese student who “has been employed by, studied at, or conducted research at or on behalf of, an entity in the PRC that implements or supports the PRC's “military-civil fusion strategy.”
The U.S. says China has been using students and scholars to gain access to key technology and, under Proclamation 10043, revoked more than 1,000 visas issued to Chinese nationals and has denied thousands more.
Critics say the policy is costly to the U.S. and is encouraging Chinese students to look to European and other universities.
