{"doi":"10.1016/j.dcn.2025.101660","title":"Contributions of neighborhood violent crime and perceived neighborhood safety to cognition and mental health in the adolescent brain cognitive development study","abstract":"INTRODUCTION: This study investigates how objective neighborhood violence and perceived neighborhood safety (PNS) relate to adolescent mental health, cognitive performance, and brain structure. We examined whether PNS moderated the effects of neighborhood violence, explored neural correlates of PNS, tested longitudinal relationships, and assessed sociodemographic and psychological predictors of PNS. METHODS: Data from the ABCD Study (n = 11,865) were used to examine associations between PNS, violent crime, and youth outcomes. Measures included youth and caregiver surveys, FBI crime data, NIH Toolbox cognitive tasks, and MRI-based brain volume metrics in stress-related regions. RESULTS: PNS, but not objective violence, was associated with fewer mental health symptoms and better cognitive performance. PNS was also related to sociodemographic variables and greater right amygdala volume. Longitudinally, baseline PNS predicted later cognitive performance, while baseline mental health and working memory predicted future PNS, indicating bidirectional effects. DISCUSSION: Perceived safety, rather than objective crime, was linked to adolescent mental health, cognition, and brain structure. PNS was influenced by sociodemographic and psychological factors, and mental health predicted declines in safety perception. These findings emphasize the developmental importance of subjective environmental experiences.","journal":"Developmental Cognitive Neuroscience","year":2025,"id":535853,"datarank":0.16479184330021646,"base_score":1.0986122886681096,"endowment":1.0986122886681096,"self_citation_contribution":0.16479184330021646,"citation_network_contribution":0.0,"self_endowment_contribution":0.16479184330021646,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":2,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9587,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":370025,"name":"Nourhan M.
