What this trial studies

This cluster randomized controlled trial adapts the Unified Protocol for Adolescents (UP-A) into an eight-week universal preventive program delivered in schools by clinical psychologists. Classes of 7th–9th graders (ages 11–18) are randomized to receive the UP-A Kind program or no intervention, with outcomes measured at baseline, post-intervention, and at 3-, 6- and 12-month follow-ups. Primary outcomes include changes in emotional symptoms and mental well-being, and secondary outcomes focus on transdiagnostic processes such as cognitive flexibility, mindfulness, and distress tolerance. The intervention is group-based, manualized, and designed for delivery in Portuguese in participating schools in Coimbra, Portugal.

Who should consider this trial

Good fit: Ideal candidates are Portuguese-speaking students aged 11–18 enrolled in 7th–9th grade at participating Coimbra schools whose guardians provide written consent.

Not a fit: Students who already need specialized mental-health treatment, who do not speak Portuguese, or who cannot attend in-person sessions are less likely to benefit from this universal prevention program.

Why it matters

Potential benefit: If successful, the program could lower future anxiety and depressive symptoms across whole school cohorts by strengthening emotion-regulation skills early.

How similar studies have performed: Randomized and nonrandomized trials of the UP-A have reduced adolescent anxiety and depression, though universal school-based adaptations have been less widely tested.
