Research > Optimizing Interventions

Picture
In our laboratory, we design and conduct rigorous evaluation studies to identify the most effective interventions and policies to improve people's lives. Evaluation studies provide important lessons for policy makers and practitioners and enhance programs to achieve the desired results in the most effective and efficient way. 


Statistical Mediation Analysis to Unpacking the Mechanisms of Interventions


Adaptability of Transported Interventions

Factorial Experiments to Optimize Interventions

Creating Adaptive Interventions to Individually Tailor Treatments

Latent Class Analysis to Identify the Subgroups of the Targeted Population  
and Support Individuals Most in Need, audience segmentation strategy

We identify the research questions concerning the program and the most appropriate evaluation design addressing those research questions in the most accurate way. We use random assignment, quasi-experimental, and mixed methods to answer the following questions: 
  • Which programs are the most effective to address the targeted outcomes?
  • Is the program effective in achieving the desired results?
  • Do program effects vary across subgroups of individuals?
  • How does the program achieve its effect? Through which mechanisms? What are the successful components of the program? What components are counterproductive and should be revised or deleted?
  • Is the program cost-effective?
  • Which program is the most outcome- and cost-effective to address the targeted outcomes?
  • If the program is not found to be effective, what were the obstacles? How can we address them?
  • Is the program well-implemented? What challenges and opportunities existed during the implementation phase? 

We value and follow scientific standards in our impact evaluation studies to ensure the findings are accurate and precise.
