Rotational Focus
Strategiesby John Bovard
A full-stack research web app designed to test whether randomly rotating focus strategies improves daily productivity and satisfaction for people with ADHD. Preceded by a 3-day pilot using rapid iterative prototyping to refine the study design.
How the study worked
Baseline · 3 days
Daily surveys with no assigned strategy. This established each participant's baseline.
Daily Focus · 4 days
Use a randomly assigned strategy each day (repeats allowed), then fill out end-of-day surveys. This tested whether strategy rotation improves outcomes.
Exit
A reflection survey along with demographic data collection.
