Engagement as Assessed by the Number of Text Messages Sent and Received by Study Participants After Enrollment. Secondary · 1 month after enrollment

A participant's engagement rate was determined by dividing the total number of participant responses to the bidirectional text messages (numerator) by the total number of bidirectional text messages sent by the text-based platform (denominator). Participants who had rates ≤33.3% were classified as having low engagement, 33.3-66.6% moderate engagement, and ≥66.7% high engagement. Data are reported categorically as number of participants who have low, moderate, or high engagement.
