Short-term digital mental health interventions reduces depression and anxiety in Ukrainian children and adolescents displaced by war
In a first of its kind randomised controlled trial, researchers found delivering a problem solving digital mental health intervention to young Ukrainian refugees significantly reduced symptoms of depression and anxiety. The findings show that a small, low-cost, scalable intervention delivered in schools through mobile devices may support the mental health of millions of displaced young people.
UNICEF reports that 47 million children and adolescents have been displaced from their homes in recent years due to war and conflict. As a consequence of the hardships and trauma they experience, these young people often develop significant mental health problems, particularly anxiety and depression. Without access to therapists who can provide appropriate mental health support in the young person’s first language, refugee children and adolescents can struggle with long-term mental health conditions. Digital interventions offer a low-cost, scalable solution to help displaced young people with their urgent mental health needs.
An international group of researchers, led by Professor JR Weisz from Harvard University and colleagues including senior author Professor Dennis Ougrin from Queen Mary University of London, tested a digital mental health intervention with 709 Ukrainian students, aged 10-18, who had been displaced to Poland.
The researchers created a Ukrainian-language version of an evidence-based digital mental health intervention called Project SOLVE. The 30-minute intervention, delivered in schools through mobile devices, teaches problem solving by providing students with strategies for solving everyday problems, such as school stress and interpersonal conflict. Standard measures of the students’ mental health were taken by participants at the start of the trial, and one and four months later.
The results, published today in The Lancet Primary Care, found that this brief mental health intervention reduced symptoms of depression and anxiety in displaced young people at one month and four months after the 30-minute intervention.
Professor JR Weisz from Harvard University said: "Children displaced by conflict are at elevated risk of long-term psychological harm, but access to mental health services is often limited or non-existent. In our trial with Ukrainian young people in Poland we found the effects of our 30-minute intervention lasted for four months. Given the need of the population and the promising findings of this trial we would like to continue to explore whether project SOLVE could be useful in other refugee settings.”
Senior author Professor Dennis Ougrin from the Youth Resilience Research Unit in the Centre for Psychiatry and Mental Health at Queen Mary, said: "Project SOLVE shows that even a single, low-cost, scalable intervention delivered through schools and mobile devices can make a difference. The results were clear: those who received the intervention reported lower levels of internalising symptoms—feelings like sadness, worry, and withdrawal—compared to peers in the control group. Among all participants, youth who received Project SOLVE had significantly lower anxiety and depression symptoms after both 1 and 4 months. Among those with high initial distress, benefits were even more striking, with effect sizes nearly doubling.” He went on: “Project SOLVE’s strength lies in its simplicity and accessibility. At a time when millions of displaced young people remain underserved, this research suggests a promising step toward meeting their urgent mental health needs - one mobile device at a time.”
The study also confirmed that Project SOLVE was easily administered in the classroom and with minimal disruption to learning. Participating students gave positive ratings on all seven items of the Program Feedback Scale and indicated that the intervention was viewed as acceptable and useful, and they would recommend it to a friend who needed support.
This study arose from a proposal by the GROW Network, a group of psychiatrists, psychologists, and other mental health professionals convened after the 2022 Russian invasion of Ukraine.

Guselkumab demonstrates superior efficacy in landmark clinical trials and offers new hope to Crohn’s disease patients
2025-07-17
New York, NY — July 17, 2025 — In a major advance for patients with Crohn’s disease, a new study led by researchers at Mount Sinai Health System found that guselkumab, a medication with a mechanism of action that is new to inflammatory bowel disease (IBD) treatment, outperformed an established standard of care in promoting intestinal healing and symptom relief.
These findings from two pivotal phase 3 trials known as GALAXI 2 and 3, published today in The Lancet, provided the basis for the recent Food and Drug Administration approval of guselkumab (brand name Tremfya) for the treatment of moderately to severely active Crohn’s ...
Here’s how the U.S. military can trim its massive carbon footprint
2025-07-17
As an institution, the U.S. military is the world’s single largest consumer of energy and emitter of climate-altering carbon pollution, on par with the entire nation of Venezuela.
Now for the first time, research by a University of Utah sociologist documented how military spending tracks in near lockstep with emissions. Brett Clark and his coauthors conclude that reducing those expenditures can lead to significant reductions of energy use and, thereby, carbon emissions.
Can the military play a role in climate ...

Cracking the code of force-driven chemistry
2025-07-17
When asked to think of a chemical reaction, you might picture bubbling liquids in a beaker, or maybe applying heat to a mixture until something transforms. But some of the most important reactions in nature and industry don’t need heat or solvents. Instead, they need force.
Mechanochemistry is where physical pressure or stress triggers chemical reactions. Imagine molecules being rammed together like bumper cars, or shaken up in a giant cocktail shaker. That shaking and colliding happens every day inside ...

Most children seeking emergency department (ED) care due to vomiting are discharged home. Although they usually feel better when they leave the ED, the vomiting recurs in nearly one-third of children.
Dr. Stephen Freedman, MD, a pediatric ED physician, led a national study to evaluate if sending children who present for care with frequent vomiting from an acute intestinal infection are better off when provided with an anti-vomiting medication to take, as needed, at home.
“When children are really sick, it’s ...
“Sisters together’: Antiracist activism and the fight for trans inclusion at the Michigan Womyn’s Music Festival
2025-07-17
The Michigan Womyn’s Music Festival, hosted from 1976 to 2015, brought together lesbian feminists for a celebration of culture and activism. Today, the festival is perhaps best known for its controversial "womyn-born-womyn” attendance policy, which excluded trans women from participation. A new article in Signs: Journal of Women and Culture in Society examines the fight for trans inclusion at Michfest and positions it within a rich history of activism at the festival, including antiracist activism by women of color.
In 1991, a woman named Nancy Jean Burkholder was expelled from the Michfest grounds on the basis ...
