As a follow up to our optimization work, this research evaluated whether text messages written with GenAI using urge-optimized prompt features produced stronger urges than generic prompts. This online survey included a within-subjects design comparing urges to move after reading messages written with generic prompts to promote physical activity, the combinations of urge features that produced the strongest urges in our optimization work (high-urge optimized), and the combinations that produced the weakest urges in our optimization work. Participants were 298 inactive adults from across the U.S. age 40 and older.
Data collection and analysis has been completed, and the manuscript is being prepared for peer review.
