This week’s roundup covers new research on screen use, teen loneliness, and anxiety, along with reports on AI chatbot safeguards for teens, emergency holds for young people in crisis, and a federal letter about parental consent for school mental health screenings.
Watchdog group says some ChatGPT for Teens safeguards did not work in its tests, and OpenAI disputes the findings
KQED, October 7, 2026
Common Sense Media’s Youth AI Safety Institute said it ran more than 4,000 test prompts on ChatGPT accounts registered to users ages 13 to 17, with child psychiatrists and a pediatrician reviewing the responses. The group reported that linked parent accounts received no alerts during test conversations about suicidal thoughts, self harm, or disordered eating, and that the chatbot missed more than one in four crisis referrals the reviewers considered warranted, though it refused sexual roleplay more consistently than before. OpenAI disputed the findings, saying parent and teen accounts must be linked for about three hours before alerts are sent and that much of the testing may have ended before parental controls were fully active. The disagreement centers on how soon parental alerts begin working after a parent links to a teen’s account.
Twin study suggests family factors explain part of the link between screen use and teen depression and anxiety
Karolinska Institutet, October 8, 2026
Researchers at Karolinska Institutet in Sweden followed more than 21,000 twins from age 9 into adulthood and published the results in the journal Nature Human Behaviour. Heavy interactive screen use at age 15, such as gaming and chatting, was linked with more symptoms of depression and anxiety, but the link became much weaker when twins from the same family were compared, which suggests that shared genes and home environment account for part of it. The authors note that the link did not disappear entirely, that screen use was self reported, and that data collection began before smartphones and social media became widespread. The findings suggest that hours of screen use alone give an incomplete picture of a teen’s risk for depression or anxiety.
Child Mind Institute survey finds nearly half of teens report moderate to severe loneliness
Child Mind Institute, October 7, 2026
A Child Mind Institute report based on a survey of 1,000 U.S. teens ages 14 to 17 found that 47 percent reported moderate to severe loneliness, and about one in five screened positive for anxiety or depression. Teens with a stronger overall sense of connection reported less loneliness and fewer anxiety and depression symptoms, and 88 percent said in person time is essential for feeling connected. The results are associations from a single survey, funded by the Morgan Stanley Alliance for Children’s Mental Health, so they do not show that low connection causes these symptoms.
Brain imaging study links differences in specific brain circuits to anxiety in early adolescence
Boston Children’s Hospital, via EurekAlert, October 9, 2026
Researchers at Boston Children’s Hospital analyzed brain imaging from nearly 3,500 young people in the Adolescent Brain Cognitive Development study and published the results in the journal Imaging Neuroscience. Weaker connections in a circuit linking the cerebellum, amygdala, and thalamus were associated with higher anxiety, with differences measurable at ages 11 to 12, while greater efficiency in other brain networks was associated with a lower likelihood of social or generalized anxiety disorders. The study describes associations and did not test any treatment, so it is an early step in understanding how anxiety develops.
Study at one pediatric emergency department finds emergency holds for youth in mental health crisis rose each year
Children’s National Hospital, October 7, 2026
A study in the journal Pediatrics reviewed 14,883 mental and behavioral health visits to an urban pediatric emergency department from 2019 through 2024 and found that about 15 percent involved a young person who arrived under an emergency hold, with hold use increasing each year. About two thirds of those visits involved transport by law enforcement, and holds were associated with longer emergency department stays and more use of physical restraint. The study looked at a single hospital and identifies associations, so the results may not reflect what happens in other communities.
Federal agencies tell states that school mental health screenings require written parental consent
K-12 Dive, October 6, 2026
The U.S. Departments of Education and Justice sent a joint letter dated October 5 to state attorneys general about school compliance with two federal laws, the Family Educational Rights and Privacy Act and the Protection of Pupil Rights Amendment. According to K-12 Dive, the letter says schools need written parental consent before using forms, surveys, or other tools to evaluate a student’s mental health, and that giving parents the option to opt out is not enough. The letter also ties federal funding to compliance with those laws. It concerns how schools ask families for permission before mental health surveys and screenings.
