Description
Emma Hovén and fifteen colleagues present the protocol for UPIC, a nationwide Swedish cohort study of mental health in adolescents and young adults. Rates of anxiety and depression in this age group keep rising, yet the processes driving the trend stay unclear, and most disorders begin in these years.
The study will recruit two thousand people aged fifteen to twenty-nine and follow them for two years under one of three schedules, from yearly check-ins to frequent phone-based momentary assessments. Data will blend app surveys, digital behaviour tests, national registers, smartphone sensor traces of sleep and movement, and home blood samples in a subset. Machine learning will hunt for trajectory patterns, and feasibility measures will judge whether such intensive collection is sustainable.
