Come work with me, Janna, Jonas, and Bart at Leiden University :). #MentalHealth #Psychology #PsychSciSky #academicsky

1/ We have a PhD position open on 'Mental Disorders as Harmful Stable States'. If you know students interested in the intersection of mental health & statistical modeling (EMA & time series), please encourage them to apply. www.academictransfer.com/nl/jobs/3621...

Photo from our recent lab dinner. Science is a team sport, and I feel incredibly fortunate to work with such an amazing group of colleagues and trainees. Beyond the papers and grants, it’s the people who make this work meaningful. Grateful for this team and excited for what’s ahead. Cheers! 🍻

In addition to a hiring PhD in ~October & hopefully some PhDs and postdocs ~February, if anyone would like to work with me as part of eg a Marie-Curie or something similar, please do get in touch. Topics include depression, classification, measurement, systems, time-series, & theory building.

Looking forward to SPR 2026 in Osaka 🇯🇵 next week, where members of our lab will be participating in several sessions focused on AI-informed interventions, digital mental health, personalization, measurement, and psychotherapy process. If you’ll be at SPR, swing by and say hello! lnkd.in/gpcYJ3Pd

Using causal ML and data from ~90,000 NHS patients, we found that only 31% received the treatment the algorithm identified as optimal. Recovery rates were 11 percentage points higher among patients with the strongest recommendations who received their indicated treatment. lnkd.in/e5Muc4BJ

Our lab will be presenting at APS in Barcelona #APS26BCN later this week. If you’re interested in digital phenotyping, passive sensing, adaptive interventions, and emotion dynamics in adolescent depression, come by our symposia and say hi. @hadarfisher.bsky.social and I will be there

I dug into NSDUH data on depression in U.S. teens (12-17) and made the below figure. Rates increased far more sharply for girls than boys, peaking around COVID before modest declines. Shaded region = % with depression receiving mental health treatment. Both depression and unmet need remain high.

For some reason, the new report of the National Survey on Drug Use and Health is geo-locked, and cannot be accessed from the Netherlands (or, I assume, from anywhere outside the US). As US based VPN solves the issue. Any thoughts why this would be the case? nsduhweb.rti.org/respweb/home...

Some evidence of decreasing depression rates among adolescents from the latest National Survey on Drug Use and Health. 60% of teens with depression reported receiving mental health treatment (31% taking meds) www.samhsa.gov/data/sites/d...

Honored to have been part of the Science of Change symposium at URI, celebrating the life and legacy of Dr. James Prochaska. I shared our work using AI and machine learning for real-time detection and scalable interventions in adolescent depression via smartphones and wearables.

Machine learning analyses in the MYRIAD trial found only clinically trivial personalization of school-based mindfulness for adolescent #Depression prevention, underscoring limited differential benefit in universal programs. ja.ma/4qUhbCL

John Torous, MD, speaks with Christian A. Webb, PhD, of Harvard Medical School and McLean Hospital, about the limits of population-level prediction and the need for more potent and targeted interventions for #YouthMentalHealth. 🎧 Listen now: ja.ma/3OSGiIw

Beyond the headline results, we discuss why meaningful personalization proved elusive – and what promising directions may move the field forward – on the @jamapsychiatry.com podcast: 🎙️https://edhub.ama-assn.org/jn-learning/audio-player/19039530

New paper from our team: Can ML identify which adolescents benefit most from school-based mindfulness? In 8,376 students (MYRIAD trial), models detected statistically significant but clinically negligible differential effects (d ≈ .07–.08). Precision prevention is hard...

Interesting to see how our lab's recruitment sources have shifted over the last 3 years (see plot). FB/Instagram used to pull 100+ responses/month, now much less productive. Methods like flyers and mailing lists remain steady. Curious if any other labs are seeing this or have found new methods?

Check out this write-up of a recent DPN article from @bbrfoundation.bsky.social highlighting BBRF awardees @christianwebb.bsky.social, @erika-forbes.bsky.social, and @diegopizzagalli.bsky.social. Congrats! bbrfoundation.org/content/smar...

Thanks to @bbrfoundation.bsky.social for highlighting our lab's study (led by @hadarfisher.bsky.social & @nigeljaffe.bsky.social) using📱smartphone sensors + LLM-derived text ratings to track behavioral activation and symptom change in teens with anhedonia. bbrfoundation.org/content/smar...

📢 New large study of ~1.5 million patients in NHS Talking Therapies finds that teens/young adults (ages 16-24) had 17-26% *lower* odds of reliably improving vs 25-65 year-olds. Time to rethink youth-centred mental-health delivery? 🔗 tinyurl.com/532y6v67

Great work Hadar!

Now out in NPP – Digital Psychiatry and Neuroscience! 📱🧠 Can LLMs and smartphone sensing help us track therapy progress in real time?

@mcleanhospital.bsky.social Technology in Psychiatry Summit #TIPS returns this year Dec 11-12. We have exciting keynotes lined up, including Drs. Pattie Maes (MIT Media Lab), Isaac Galatzer-Levy (Google DeepMind), and Derrick Hull (Slingshot AI). Submissions are now open. See below for info.

📱EMA is increasingly used in intervention studies to acquire a more fine-grained and ecologically valid assessment of change. But EMA is relatively burdensome. What's the added value? We tried to address this question in our new paper now out @jmirpub.bsky.social www.jmir.org/2025/1/e69297 1/n

There is still time to submit your symposium, workshop, or poster for the 2025 Technology in Psychiatry Summit (TIPS). Submission deadline is Oct 9. TIPS is taking place virtually as a 2-day meeting Dec 11th and 12th, 2025. #TIPS #technologyinpsychiatry Link: techinpsych.org
