Effects of a group-based cognitive behavioral therapy for sleep in nursing students: Pilot randomized controlled trial. JMIR Human Factors, 13, e85021-e85021. https://doi.org/10.2196/850212292-9495https://hdl.handle.net/11268/17455Sleep quality is a strategic public health priority and a key factor in the study of circadian rhythms and chronotypes. Nursing students are a particularly vulnerable population group. This pilot randomized controlled trial provides preliminary evidence that a brief group-based CBT-I intervention may improve selected subjective sleep outcomes, particularly sleep latency, among first-year nursing students. Objective circadian rhythm and sleep outcomes showed generally small treatment effects. Given the exploratory nature of this pilot study, adequately powered randomized controlled trials with longer follow-up are needed to confirm these preliminary findings.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Medicina, Salud y DeportesTerapia Cognitivo-ConductualEstudiantes de EnfermeríaEnsayos Controlados Aleatoriosjournal article10.2196/85021open accessCiencias médicasPsicologíaMedicina preventivaGoal 3: Ensure healthy lives and promote well-being for all at all agesGoal 4: Quality education
