 This study aims to conduct a scoping review on wearable devices that can augment current in-person physician assessments for individualizing diagnosis and management of psychiatric disorders in child and adolescent psychiatry. The results show a large heterogeneity of methods and findings in artificial intelligence studies, with most studies using cardiophitness chest straps or wrist-worn biosensors for passive data collection of physiological signals. However, the lack of randomized controlled trials is identified as the largest gap in this scoping review. This article was authored by Victoria Welch, Tom Joshua Way, Anna Lageska, and others.
