Short answer

Designers should actively engage target user groups, particularly older adults, in the co-creation of digital health tools like nutrition chatbots to ensure their long-term usability and effectiveness.

Field: User-Centred Design
Source: i-com (2023)
Method: Participatory Design Case Study
Sample: 15 participants
Evidence: Moderate effect

Involving older adults directly in the co-design and evaluation of nutrition chatbots leads to more effective and sustainable adoption of the technology. This user-centred design research insight is drawn from a 2023 study published in i-com. Using Participatory design case study with 15 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers should actively engage target user groups, particularly older adults, in the co-creation of digital health tools like nutrition chatbots to ensure their long-term usability and effectiveness.

Application

Design takeaway

How to apply

When designing digital health solutions for specific demographics, initiate user research early and involve users in iterative design and testing cycles.

Project actions

01When designing for a specific user group, consider their unique needs and preferences from the outset.
02Involve potential users in the design process through workshops, interviews, and usability testing.

Method & Evidence

AimHow can a participatory design approach be effectively realized to co-design, evaluate, and develop nutrition chatbots for older adults, and what are the implications for their long-term use?

MethodParticipatory Design Case Study

ProcedureThe study involved older adults in multiple phases: initial co-design workshops to gather requirements and preferences, followed by real-world evaluation studies where participants used the developed chatbot over several weeks to assess its usability and impact on dietary management.

Sample15 participants

ContextDigital Health / Nutrition Coaching

Variables

IVParticipatory design approach (vs. non-participatory)

DVLong-term engagement and usability of the nutrition chatbot

CVAge of participants, specific health goals, technological literacy

Strengths & Limitations

Strengths

+Employs a participatory design methodology, directly involving users.
+Focuses on long-term evaluation, addressing a gap in existing research.

Limitations

Small sample sizes in user testing can limit the confidence in the findings.

Reliability & validity

The study's validity is strengthened by its participatory approach and long-term evaluation, but reliability might be affected by the small sample size in later stages.

Think critically

How might the findings of this study be applied to other types of digital services beyond nutrition coaching, and what adaptations would be necessary?

Design Principles

"User participation in design leads to more successful and sustainable product adoption."

This research highlights the critical role of user involvement in developing digital health tools. For designers, it underscores that a one-size-fits-all approach is insufficient, and tailoring interfaces and functionalities based on direct user feedback is paramount for long-term success, especially with specific demographic groups.

What This Means for Your Design

If you want to make a digital tool (like an app or chatbot) that older people will actually use for a long time, you need to ask them what they want and test it with them as you build it.
