Building Understanding of Transitions Trauma, in Early Formative Life Years (BUTTERFLY) Dataset

The Biopsychosocial Longitudinal Outcomes in Addiction Medicine (BLOOM) Lab has developed three datasets to explore how adverse childhood experiences (ACEs) and prenatal substance exposures are associated with psychiatric outcomes in at-risk populations, such as children in foster care or recently adopted. The first dataset, BUTTERFLY (Building Understanding of Transitions, Trauma, Early Life Years), includes patients seen at the Adoption Medicine Clinic at the University of Minnesota (AMC-UMN) between January 1, 2014, and December 31, 2024. The patient population comprises international and domestic adoptees, as well as individuals in the foster care system under 21 years old. The data captured in the BUTTERFLY dataset includes patient history (general birth outcomes, caregiver placement history, prenatal substance exposures, and ACEs) from birth up to the first Comprehensive Child Wellness Assessments encounter; experiences after this period are not captured in this dataset.
