Elizabeth Weigensberg is an expert on designing and conducting evaluations, using both qualitative and quantitative methods, and developing and estimating performance measures for public child welfare agencies and workforce development programs. Her expertise includes linking and analyzing complex administrative data from state and local public agencies and providing technical assistance to facilitate the development and use of data to inform policy and practice.
Weigensberg helps lead Mathematica’s work with developing data, advanced analytic, and program improvement solutions for state and local child welfare agencies. She has also contributed to numerous research projects on child welfare and workforce development. She currently directs a project creating a data resource documenting states’ definitions and policies related to the incidence of child abuse and neglect for the U.S. Department of Health and Human Services, Administration for Children and Families, Office of Planning, Research, and Evaluation and the Children’s Bureau. She also leads evaluation activities for the Center for Native Child and Family Resilience, which is a Quality Improvement Center designed to support tribal communities in building evidence to prevent and intervene in child maltreatment. She has recently led a qualitative study for the U.S. Department of Health and Human Services, Assistant Secretary for Planning and Evaluation to describe the relationship between foster care and substance use in local communities. She recently directed a project with Casey Family Programs that involved linking child welfare administrative data with Medicaid data and applying advanced analytics to identify types of super-utilization of services and predictors of placement instability for children in foster care.
Weigensberg came to Mathematica in 2015 from Chapin Hall at the University of Chicago, where she was a senior researcher and principal investigator on numerous projects. She previously worked as a research instructor at the University of North Carolina at Chapel Hill and as an analyst at the U.S. Government Accountability Office. She holds a Ph.D. in social work from the University of North Carolina at Chapel Hill and an M.S. in social work from Columbia University.
Building Capacity to Evaluate Interventions for Youth with Child Welfare Involvement at Risk of Homelessness: Phase I and II
ACF funded 18 grantees to develop and test comprehensive programs to reduce homelessness among former foster youth. Mathematica is providing implementation technical assistance to six grantees to strengthen their abilitly to use data to make evidence-based decisions.
Superutilization of Child Welfare and Other Services
Reducing the number of children in foster care requires actionable policy and practical solutions. By identifying subpopulations of children and youth who use intensive or frequent services, we might shed light on those who lack the right types of support at critical junctures, live in overly restrictive...
Design Options for Understanding Child Maltreatment Incidence
This project will result in a set of rigorous and creative design options to address critical research questions and improve ongoing surveillance of child abuse and neglect as well as related risk factors.
