{"doi":"10.31234/osf.io/7d8yp","title":"Perception of social experiences and cortical thickness change together throughout early adolescence: findings from the ABCD cohort","abstract":"Early adolescence is a dynamic period of social and cortical development amidst rapid hormonal and puberty changes. We examined how differences and changes in positive social experiences and cortical thickness co-develop from age 9-11 and 11-13 years in the ABCD cohort (N~12,000). We used Bivariate Latent Change Score Models to capture cortical development (modelling mean whole-brain cortical thickness) and positive social experiences (modelling caregiver monitoring, family cohesion, prosocial behaviour, number of friends, school engagement, school involvement, and neighborhood safety). We found that positive social experiences decreased between age 9-11 years (baseline) and 11-13 years (2-year-follow-up), indicating that social experiences were perceived as less positive over time. We found evidence for correlated change, such that a greater reduction in positive social experiences was associated with a greater reduction in cortical thickness (est=5.23, SE=1.31, p<.001, standardized coefficient=.08), which did not differ between males and females in early and late puberty stages. We found mixed evidence for sex-specific relationships between puberty stage and social experiences; highlighting the need to better understand males’ puberty and social experiences in early adolescence. The evidence supports a transactional model of development in that positive social experiences and cortical thickness change together throughout early adolescence. The findings also highlight the importance of supporting youth in early adolescence through school transitions.","journal":null,"year":2023,"id":414566,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.8902,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1131997,"name":"Ayla Pollmann","orcid":"0000-0001-8471-8869","position":1,"is_corresponding":false},{"id":257919,"name":"Rogier Kievit","orcid":"0000-0003-0700-4568","position":2,"is_corresponding":false},{"id":1131999,"name":"Delia Fuhrmann","orcid":"0000-0003-4678-8828","position":3,"is_corresponding":false},{"id":1131998,"name":"Kathryn E Bates","orcid":"0000-0001-8188-6058","position":0,"is_corresponding":true}],"reference_count":46,"raw_metadata":{"citation_network_status":"fetched"},"created_at":"2026-07-19T01:22:05.177070Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
