Internalizing problems like worrying, anxiety, and low mood are increasingly common in youth and may signal early-stage mental illness. This randomized controlled trial will test whether a mindfulness-based program called Learning to Offset Stress, added to usual care, reduces internalizing symptoms in 155 help-seeking youth aged 16–25. The program combines mindfulness exercises with mindful physical activity and yoga over eight weekly sessions. Assessments occur at baseline, end of treatment, and at two and six months after treatment. The primary outcome is the level of internalizing problems measured by the Adult Self Report questionnaire. Secondary outcomes include self-compassion, rumination, experiential avoidance, and well-being, along with brain imaging and cognitive tasks. The trial aims to clarify how early mindfulness intervention may alter symptom development and mental illness progression.

Efficacy and acceptability of ketamine and esketamine in adults with treatment-resistant major depressive disorder: systematic review and meta-analysis

Open Science Framework January 1, 2026 Annemarie van der Meij, Sotiris Poyiadis, Andrea Cipriani et al.

This preregistration describes an update and extension of a meta-analysis examining ketamine and esketamine for adults with treatment-resistant major depressive disorder. The project is nested within a larger network meta-analysis of next-step strategies for treatment-resistant depression. It restricts interventions to ketamine and esketamine regimens versus placebo, structures outcomes into three time windows (24–72 hours, 1–3 weeks, and 4–12 weeks), and pools results using pairwise random-effects meta-analyses rather than network meta-analysis due to expected lack of direct comparisons between treatment nodes. Short-term outcomes will be extracted from longer-term trials. Subgroup and meta-regression analyses are exploratory.
