The paper "Building towards an adolescent neural urbanome: Expanding environmental measures using linked external data (LED) in the ABCD study" by Carlos Cardenas-Iniguez et al. explores the impact of environmental contexts on child and adolescent neural and behavioral development. The authors emphasize the importance of geospatial methods, such as those used in the Adolescent Brain Cognitive Development (ABCD) Study, to explore environmental factors surrounding participants' residential locations without burdening them. They introduce the concept of the "adolescent neural urbanome," a framework that categorizes newly geocoded information incorporated into the ABCD Study by the Linked External Data (LED) Environment & Policy Working Group. This framework aims to refine contextual constructs, integrate them into an "urbanome" theoretical framework, and adopt a social justice-oriented approach. The paper highlights the importance of responsible use and communication of these data, particularly regarding historically minoritized groups. The authors describe the process of characterizing the environment and generating residential histories in the ABCD study, detailing the criteria for selecting external datasets and the subdomains of the Adolescent Neural Urbanome. They also provide recommendations for responsible data use and communication, emphasizing the potential harm to historically minoritized groups through misuse.The paper "Building towards an adolescent neural urbanome: Expanding environmental measures using linked external data (LED) in the ABCD study" by Carlos Cardenas-Iniguez et al. explores the impact of environmental contexts on child and adolescent neural and behavioral development.
