Repeated Digital Nudge Effects on Healthy Online Meal Orders

A 2026 study by Ildiko Krisztina Preiner explores the effects of repeated digital nudges on healthier food choices in an online meal ordering context. The dataset likely contains results from a three-day experiment with 154 participants randomly assigned to Feedback, Assortment, Combined, or Control conditions. Participants made hypothetical daily lunch orders, each including a main dish, side dish, and drink, with health scores tracked over time.

Use Cases

• Analyzing the decay or persistence of nudge effects over three days based on the repeated exposure experiment.
• Comparing the effectiveness of structural (Assortment) versus moment-of-choice (Feedback) nudges based on the condition assignments.
• Modeling composite health score changes driven by side dish and drink selections based on the component-level analysis mentioned.
• Evaluating the potential of combined nudges to sustain healthier choices based on the 24% higher score result.

Strengths

• Experimental design with random assignment to four conditions (Feedback, Assortment, Combined, Control).
• Includes a composite health score metric with a reported 24% improvement and effect size (d=0.66).
• Tracks component-level choices (main dish, side dish, drink) over a three-day period.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a mock platform with hypothetical orders, which may not reflect real-world behavior.
