Thank you CBS @wbz for covering our work on teen depression on your show this evening! via @wbz.

Teenagers are experiencing higher rates of depression than ever before, but a simple smartphone app could help treat a common symptom.

Focusing only on individual-level interventions risks overlooking broader influences. Future precision prevention should integrate multilevel data—capturing both individual and contextual drivers of outcomes. 6/n.

Youth mental health ≠ just individual factors. School climate, poverty & inequities matter too. Prevention must move beyond one-size-fits-all to integrate both personal + systemic influences. 5/n.

Machine learning can identify which adolescents are more likely to benefit from SBMT vs. TAU. This may point to a path toward precision prevention in schools. Next step: prospective trials testing whether algorithm-guided intervention assignment improves outcomes. 4/n.

We used ML on baseline student + school characteristics to predict change in depression in SBMT vs. TAU. Results:.• 19% of students fared better with SBMT (d = 0.22).• 37% fared better with TAU (d = 0.22).• Compared to negligible average between-group effects (d = 0.03).3/n.

The MYRIAD trial compared school-based mindfulness training (SBMT) vs. teaching as usual (TAU) in > 8,000 teens in 84 UK schools. SBMT did *not* outperform TAU in the overall trial. Background via NYT: 2/n.

Recent studies cast doubt on whether large-scale mental health interventions are making young people better. Some even suggest they can have a negative effect.

🚨 New research alert. We applied machine learning to the large MYRIAD trial (84 schools and 8,376 UK teens) to ask:. 👉 Which adolescents benefit most from mindfulness delivered in schools?. Bottom line: One-size-fits-all doesn’t work. Paper link: 1/n.

Congrats to lab member @hadarfisher and her new paper showing that emotion rigidity (assessed via EMA) in youth predicts future depressive symptoms over a 2 year follow-up.

🚨 Preprint alert! 🚨. Can we track therapeutic change outside the clinic?.In a new preprint, we explored whether digital tools - smartphone sensors📱 and LLM (GPT-4o) 🤖- can track daily-life activation in adolescents receiving Behavioral Activation (BA) therapy for anhedonia.
