Treatment and study plan

SmokefreeSGM

Behavioral

Participants will have access to a text-based smoking cessation program tailored to sexual minority individuals (SmokefreeSGM). The text-based program will be beta-tested by these participants for a period of 2 weeks before and 10 weeks after their quit date. Messages originated from the text-based smoking cessation program will be sent by a fictitious quit coach who will offer evidence-based advice on quitting smoking based on real-life experiences of sexual minority individuals.

Primary outcomes

  1. Perceived Usability as Assessed by the System Usability Scale (SUS)

    Time frame: 1 month after quit date

    The 10-item System Usability Scale (SUS) was used to assess the usability of the SmokefreeSGM text messaging program. Total score ranges from 0 to 100, with a higher score indicating greater acceptability and a score above 75 indicating that the program is perceived as acceptable.

Secondary outcomes

  1. Engagement as Assessed by the Number of Text Messages Sent and Received by Study Participants After Enrollment.

    Time frame: 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.
