Clinical trials

This cluster randomized controlled trial will evaluate whether a brief, school-based group adaptation of the Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C) improves sleep and mental health in adolescents aged 14 to 17 years. Public secondary schools in Navarre (Spain) will be randomly assigned, stratified by urban/rural location, to deliver either TranS-C or an attention-matched healthy-habits psychoeducation program. Both programs consist of four weekly 45-minute group sessions delivered during school hours by trained psychologists. The main questions it aims to answer are: Does TranS-C improve sleep quality and daytime sleepiness compared with the control program? Does TranS-C reduce anxiety-depressive symptoms, psychotic-like symptoms, interpersonal difficulties and substance use compared with the control program? Participants will complete self-report questionnaires at baseline, after the intervention, and 3, 6 and 9 months after the intervention.

This research project is structured in two phases: an initial observational phase and a subsequent randomized controlled trial (RCT) phase. The goal of the observational phase is to compare hospital admission and Hospital at Home (HaH). The objective of the RCT is to assess the effectiveness of a multicomponent intervention following acute hospitalization in older adults. The main questions it aims to answer are: * What are the differences between hospital admission and HaH in sedentary and physical activity levels? * What are the effects of a multicomponent intervention following acute hospitalization in older adults? Researchers will compare a post-discharge multicomponent intervention to usual care to see the effects on physical and cognitive function. Participants will receive a home-based cognitive and physical exercise intervention or usual care.
