Developing data-driven personas using mixed methods, combining quantitative clustering with qualitative insights from statewide surveys, leads to more realistic and actionable user representations for public health information system design. This user-centred design research insight is drawn from a 2026 study published in Online Journal of Public Health Informatics. Using Mixed methods (quantitative cluster analysis and qualitative thematic review) with 1103 (initial survey), 143 (subset survey), researchers explored how this design variable affects real-world outcomes. The key design takeaway: Integrate quantitative segmentation techniques with qualitative data analysis to build rich, data-backed personas that accurately represent diverse user groups for more effective design outcomes.

Key Findings
- 01K-prototype clustering identified 5 distinct user segments.
- 02These segments were further developed into 13 detailed personas, reflecting variations in demographics, technological readiness, and attitudes towards public health policies.
- 03Personas were enriched with qualitative quotes to provide deeper context and realism.
Application
Design takeaway
Integrate quantitative segmentation techniques with qualitative data analysis to build rich, data-backed personas that accurately represent diverse user groups for more effective design outcomes.
How to apply
When designing information systems for large or diverse populations, utilize existing large-scale survey data. Employ cluster analysis to identify key user segments and then use qualitative data (e.g., open-ended responses, interview transcripts) to flesh out these segments into detailed, actionable personas.
Project actions
- 01Consider using existing datasets if available for your design project to build data-driven personas.
- 02Think about how to combine different types of data (e.g., survey results, interview notes) to create richer user profiles.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilizes real-world, large-scale survey data.
- +Employs a rigorous mixed-methods approach for robust persona development.
- +Provides actionable personas for design applications.
Limitations
The personas created might not capture all nuances of user behavior if the original survey data was limited in scope.
Reliability & validity
Reliability is enhanced by using established statistical methods (cluster analysis) and a structured qualitative analysis process. Validity is supported by grounding personas in comprehensive survey data that captures a wide range of relevant user characteristics.
Think critically
How might the choice of statistical analysis (e.g., k-prototypes vs. k-means) impact the resulting user segments and subsequent personas?
Design Principles
"User representations should be grounded in empirical data to ensure relevance and effectiveness in design."
This approach moves beyond generic user profiles to create personas that accurately reflect the diverse needs, technological capabilities, and attitudes of a target population. This grounding in real data ensures that design decisions for public health systems are user-centric, leading to more effective and widely adopted tools.
What This Means for Your Design
This study shows how to create realistic 'user profiles' (personas) for designing health websites or apps by using survey data. They used math to group people and then looked at what people said to make these profiles very detailed and useful.

Paragraph starter
To ensure the developed design solution effectively addresses user needs, a data-driven approach to persona development was employed, drawing inspiration from methodologies like that of Garcia et al. (2026). This involved utilizing quantitative data analysis to identify distinct user segments, followed by qualitative insights to enrich these segments into detailed, actionable personas that reflect the target audience's characteristics and behaviors.
