SUMMARY:Comparing Cognitive Walkthrough and Usability Testing for Evaluati
 ng a Caregiver Symptom-Tracking Health Application
DESCRIPTION:Cecile Darwiche, Paulina Fiore, Jamie Gonzalez, and Barbara Mi
 llet (University of Miami)\n\nThis research compares two usability evaluat
 ion methods, Cognitive Walkthrough (CW) and Usability Testing (UT), in ide
 ntifying design issues in a gastrointestinal symptom-tracking application 
 for caregivers of people with neurodevelopmental disorders. Digital health
  tools increasingly support caregivers in tracking symptoms and managing c
 are, but poor usability can compromise the integrity of the health data th
 ese tools are designed to capture. Three CW evaluators and seven UT partic
 ipants completed the same six tasks with the application. Across both meth
 ods, 17 usability issues were identified: 6 detected by both CW and UT, 4 
 unique to CW, and 7 unique to UT. CW surfaced system-level and workflow pr
 oblems such as broken flows, missing feedback, and misleading navigation, 
 while  UT revealed experiential challenges, including confusion, frustrati
 on, and misunderstandings about the app's intended use. This study also de
 scribes how issues confirmed by both methods were used to prioritize redes
 ign decisions under resource constraints.\n\n
