Designing for the Moment: How One-Minute Interventions Fit or Falter Across Domains
For designers of behavior change interventions, this work explores lightweight personalization mechanisms to improve engagement.
This paper investigates one-minute digital interventions designed to prompt immediate action without onboarding or sensing, using Fogg's Behavior Model. A 14-day study with 22 participants across three domains (physical activity, healthy eating, mental well-being) found that co-authorship personalization balances relevance with low friction.
This paper explores the design space for one-minute digital interventions that prompt immediate action without onboarding or sensing. By embracing Fogg's Behavior Model and four design principles informed by literature, the goal of these interventions was to provide triggers that encourage actions so simple that even people with low motivation would be willing to complete them. We examined the utility of these prompts by conducting a 14-day study with 22 participants interested in making small lifestyle improvements in at least one of three domains: physical activity, healthy eating, and mental well-being. When combined with insights drawn from participants' rewrites of our prompts, our findings suggest that intentional personalization through co-authorship could be a lightweight personalization mechanism that balances relevance with low friction.
