Abstract

Objective: To assess the impact of incorporating nudge strategies in the design of a nutrition education workshop invitation on workshop registration among early childhood education and care centers.

Methods: A parallel-group randomized controlled trial was conducted with 88 centers. Centers received nudge strategies embedded within an enhanced invitation (intervention) or a generic invitation (control) to attend a nutrition education workshop. Center workshop registration and invitation recall and acceptability were compared between the 2 arms.

Results: No statistically significant differences in workshop registration (25% vs 20%; P = 0.61), invitation recall (69% vs 62%; P = 0.58) or acceptability (mean: 8.38 vs 8.06; P = 0.50) were found between intervention and control centers, respectively.

Conclusions and implications: Low-intensity behavioral strategies embedded in the design of an invitation were insufficient to increase workshop registration significantly. Investigation and application of alternate evidence-based nudge strategies to encourage staff participation in nutrition education in early childhood education and care setting are recommended.
