Design outcomes

Primary

MeasureTime frame
Feasibility related outcomes: 1. Recruitment and retention rates Measured by identifying the number of participants taking part in the study (from start to end) and number of participants who withdraw from the study at any point. 2. Engagement with the intervention Engagement rates will be assessed by program usage. Analytics will be retrieved weekly, including the amount of times a participant logs into the program, how many modules they access, how long they spend on each module and how frequently they access the progress tracking page 3. Usability and participant satisfaction Obtained as part of a process evaluation through telephone interviews with a subset of participants following the 7-week assessment time point, as well as a satisfaction survey completed by all participants during the 3-month assessment time point.
