Usability testing of tablet-based cognitive behavioral intervention application to improve a simple walking activity for older adults with arthritis fatigue.

The purpose of this study was to test usability of a tablet-based cognitive behavioral intervention ("Tab-CBI") application. Tab-CBI was designed to improve a simple walking activity for older adults with arthritis fatigue. Two phases of usability evaluation were conducted: phase I with 5 older adults to identify any initial design issues and phase II with 10 older adults to examine if Tab-CBI was seamlessly integrated into their daily living. Participants perceived that Tab-CBI was easy, light, and intuitive to use and helped them walking. They reported two key benefit as a motivator to make more active in walking and improved confidence of self-management of fatigue. They referred video recordings and videoconferencing communications as two preferable features. There were also comments for improvement, for example, a challenge for holding a tablet when videoconferencing communications. Participants comments were incorporated into a final version of Tab-CBI to prepare for a future pilot study.
