Mathematica designs and executes large- and small-scale studies that address today’s pressing policy questions across multiple program areas, research methods, and locations.
Our strengths include designing and conducting studies of program implementation and effectiveness. We also integrate studies of operations and effects to generate actionable findings for decision makers, develop conceptual frameworks and logic models, and design demonstrations for new initiatives.
We help clients develop and implement designs that provide the most credible and actionable information within the time and resources available by addressing the following questions:
- What are the client's most pressing research questions concerning the program to be evaluated?
- What is the strongest evaluation design that could be used to answer the questions, minimizing bias and maximizing precision?
- What are the assumptions underlying the proposed approach, and how can we test them to ensure the findings will be robust and defensible?
- How do program effects vary across important subgroups of individuals or sites participating in the study? How are other stakeholders affected by the program being evaluated?
- If the program is found to have the desired effects, how will we identify the primary determinants of success? If the program does not have the desired effects, what barriers were most responsible?
- How will the results from impact and implementation analyses be integrated to ensure the client has a clear and consistent set of answers to key questions?
- What are the possible challenges to the research, and how can we address them effectively?

Adapting a Model of Integrated and In-Home Care to Serve Medicaid Patients with Multiple Chronic Conditions
This project encompasses Mathematica’s evaluations of Landmark Health’s home-based intensive care model as it was delivered to complex Medicaid and dually eligible beneficiaries in California from 2016-2020. The evaluation assessed the model’s impacts on health care utilization and quality.
