Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are University of Florida students aged 18+ who own a smartphone, are willing to wear a wrist device, and complete frequent brief check-ins for five weeks.
✕Probably not a fit
Participants whose reactions are not influenced by momentary prompts or who do not experience rapid affective shifts may see no benefit.

What this trial studies
This pilot micro-randomized trial uses a wearable and smartphone prompts over five weeks to see if momentary coping messages affect short-term behaviors related to emotion and self-regulation. After a one-week run-in to establish personal affect variability, messages are randomly delivered at up to six decision points per day when emotional volatility is high. The study analyzes proximal outcomes within two hours after each decision point to estimate the causal effect of prompts. Feasibility and effect size are the main goals to inform future work in just-in-time interventions for college students.
Why it matters
Potential benefit: If successful, timely coping prompts could reduce impulsive online reactions, drinking, or emotional eating in moments of high emotional volatility.
How similar studies have gone: Prior research in electronic momentary interventions has shown promise, but this exact approach with randomized prompting at high-variability moments is exploratory.
