SMS Participation
12 Participants

PRIMARY outcome

Timeframe: Week 12

Population: Only 8 people in the SMS arm completed the questionnaire.

Participants will complete the SUS in person on an I-Pad or over the phone. The SUS yields a single score on a scale of 0-100. A SUS score above a 68 would be considered above average (better) usability.
