Promoting Dairy Consumption Among Families: Development and User Experience Study of a Web-Based Nutrition...

Area of Science:

• Nutrition Interventions
• Digital Health
• Behavior Change Theory

Background:

• Adherence to dietary guidelines, including dairy intake, is a challenge for Canadian families.
• Web-based interventions grounded in user research and behavior change theories show promise for improving diets.
• Few digital interventions specifically target family dairy consumption.

Purpose of the Study:

• To describe the development of Dairyathlon, a web-based intervention promoting dairy consumption in families.
• To evaluate the user experience (UX) of the Dairyathlon platform.
• To utilize the IDEAS (Ideate, Design, Assess, Share) framework for intervention development.

Main Methods:

• Ethnographic research and interviews explored family perspectives on dairy consumption.
• Behavior change techniques based on the theory of planned behavior were integrated.
• Iterative design, prototype testing, and refinement were employed, with UX assessed using AttrakDiff.

Main Results:

• Dairyathlon development adhered to the IDEAS framework, enhancing attitudes and control over dairy intake.
• Significantly higher UX scores for Dairyathlon compared to the Canadian Food Guide (CFG) were observed (P<.001).
• Children rated all UX dimensions as optimal; parents rated most dimensions as optimal, with stimulation needing improvement.

Conclusions:

• The IDEAS framework effectively guided the development of the Dairyathlon web intervention.
• Dairyathlon demonstrated optimal user experience, particularly in attractiveness, with potential for improved adult stimulation.
• Future research will assess Dairyathlon's impact on dairy consumption, diet quality, and family health.
