The dataset contains the raw data (ades_aggregated, minikid_raw) and the workfile (dissociation_FINAL) used for the analyses of the study published by Fragkaki, Weijman, and Cima (2019) in Journal of Youth and Adolescence. The current study is part of a larger project examining biological and environmental factors associated with antisocial behavior in youth and it is focused on the association between dissociation and psychopathology in 101 male adolescents living in residential youth care facilities (one participant did not complete the study and was excluded from the analyses). Dissociation was assessed with the Adolescent Dissociative Experiences Scale and psychopathology was assessed with the Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID). Logistics regressions were performed to examine whether dissociation was related to psychopathology controlling for childhood trauma, callous-unemotional traits, and age. The documentation file includes information about the methodology of the study, the sample, and the variables in the datasets. The published paper describes the methodology, procedure, and analyses in detail.
