Mathematica is one of two policy research centers that lead the SSA's Disability Research Consortium. The DRC fosters new research from a team of disability policy experts from Mathematica and three universities.
- Vocational rehabilitation for people with disabilities
- Participation in the SSDI and SSI programs by adults and children with disabilities
- Issues related to retirement behavior
- Program evaluation
- Employment and Income Support
- Statistics and Measurement
Purvi Sevak’s primary research interest is in policies to support the employment and well-being of people with disabilities and chronic conditions. Her work spans the fields of health, employment, and program evaluation.
Sevak has expertise in the role vocational rehabilitation (VR) plays in helping people with disabilities achieve their employment goals. She currently works with state VR agencies to help them leverage data and technology to improve service delivery and outcomes for youth with disabilities as they transition to adulthood. This includes developing and supporting the Vocational Rehabilitation Program Evaluation Coach, a free web-based tool that assists VR agencies with evaluation to inform program improvement. Sevak recently co-edited a special volume of the Journal of Vocational Rehabilitation, a collection of studies on the role of individual and environmental factors in influencing employment of people with disabilities.
Sevak has extensive research and program evaluation experience. She has designed or led the quantitative evaluation of several notable federally funded interventions, including two Health Care Innovation Awards for the Centers for Medicare & Medicaid Services and the Substantial Gainful Activity Demonstration for the Rehabilitation Services Administration. Her published research has included studies examining program participation in Supplemental Security Income, geographic variation in employment and program use, barriers and facilitators to employment, retirement and savings behavior, and the ability of intensive care management to improve outcomes for Medicare beneficiaries with complex health needs.
Sevak holds a Ph.D. in economics from the University of Michigan. She has been at Mathematica since 2013 and was previously a professor in the economics department at Hunter College in the City University of New York.
Substantial Gainful Activity (SGA) Project Demonstration
Mathematica is helping to develop a demonstration focused on improving the employment outcomes of state vocational rehabilitation clients who receive only SSDI benefits.
High-Intensity Care Management Program Shows Promise for Reducing Hospital Use and Spending for Super Utilizers
Recently published findings from an evaluation conducted by researchers at Mathematica found that a high-intensity care management program modeled on the Camden model led to substantial reductions in short-term service use and spending for a small group of super utilizers in four states.
