Use, Usability, and Experience Testing of a Digital Health Intervention to Support Chronic Kidney Disease Self-Management: Mixed Methods Study

Access to and use data of MK&M were collected, alongside perceived usefulness (scored from 0 [not useful at all] to 10 [very useful]) of MK&M content and features. The frequency and length of time spent on MK&M sessions, health and symptom tracker use, and use of other MK&M features (eg, goal setting) were collected via the MK&M platform. Perceived usefulness of MK&M content and features were collected via web-based surveys.

A 10 m walking track will be prepared and marked (Figure 4 A). Participants will be instructed to walk for 5 seconds (repeated 3 times), then for 15 seconds (repeated 3 times), and then for 30 seconds (repeated 3 times) for 9 trials (Figure 4 B). Step counts from the Fitbit device will be recorded at the beginning and end of each trial. If participants reach the end of the 10 m track, they will be instructed to turn around and continue walking in the opposite direction. In-laboratory data collection.
