A Mixed Method Approach to Validity to Help Build Trust
Speakers: Chris Engledowl

Summary

Quantitative instruments are frequently sought because 1) they can be quickly fielded to lots and lots of people, and 2) when carefully sampled, they can be generalizable to the population of users/customers. However, because many times the focus is on speed to launch because decision-makers need results quickly, there is not much depth given to their development, nor an investigation of the validity evidence. In the session, I will share a framework that centers validity and is necessarily a mixed methods approach to research. I will also share ideas on how to scale the research over time so that findings and insights are able to be iteratively delivered to stakeholders, while also iteratively informing one another in a qual-quant research dance that brings more trustworthy, user-centered evidence to decision-makers. Finally, I will share ideas for a course I am developing for supporting qualitative researchers to become more mixed in their approach.

Key Insights

  • A mixed-methods approach enhances validity and trust in survey research.

  • Validity is crucial in both qualitative and quantitative research to ensure accurate interpretations.

  • Engaging stakeholders early in the survey design process leads to better alignment with their needs.

  • Cognitive interviews can uncover participant understanding and response processes, refining survey items.

  • Iterative testing of surveys allows for continuous improvement and insight generation over time.

  • It's important to address both the ethical implications of survey questions and their potential impact on participants.

  • Researcher collaboration between quant and qual experts strengthens the validity argument.

  • Surveys should be treated as products requiring careful design and testing before deployment.

  • Identifying and understanding subpopulations can reveal biases and improve survey accuracy.

  • Validity assessments should be continuous, reflecting changes in user bases and research goals.
