Mixed methods research enhances impact evaluations by improving policy relevance and addressing external validity. Increased use of these approaches can reinforce findings and explain program successes or failures.
Area of Science:
- Social Sciences
- Policy Evaluation
- Research Methodology
Background:
- Impact evaluations are crucial for assessing program effectiveness.
- External validity and generalization are key challenges in research.
- Mixed methods offer potential solutions to these challenges.
Purpose of the Study:
- To explore the utility of mixed methods in enhancing impact evaluations.
- To investigate the application of mixed methods for external validity.
- To document the current use of mixed methods in impact evaluations.
Main Methods:
- Literature review on rationales for mixed methods.
- Systematic documentation of mixed methods in recent impact evaluations.
- Full-text review of selected impact evaluation articles.
- Analysis of exemplar case studies.
Main Results:
- Mixed methods are underutilized in current impact evaluations.
- Mixed methods can reinforce quantitative findings through triangulation.
- Mixed methods help elucidate program impact mechanisms and reasons for failure.
Conclusions:
- Increased adoption of mixed methods can significantly improve impact evaluation value and policy relevance.
- Mixed methods are essential for addressing external validity and generalization issues.
- Further research and application of mixed methods are recommended for robust program evaluation.
