Designing and pilot-testing SmokefreeSGM: a text-based smoking cessation intervention for sexual and gender minority groups.

Background: Although the prevalence of smoking is significantly higher among sexual and gender minorities (SGM) than the general population, no text-based smoking cessation intervention has been specifically tailored to this group. The objective of this phase of our study was to develop SmokefreeSGM, an SGM-tailored text-based smoking cessation program, and pilot test its design to inform the refinement of the program.

Methods: SmokefreeSGM was adapted from SmokefreeTXT, the National Cancer Institute's text-based smoking cessation program, to respond to the needs of SGM smokers. In addition to tailored text messages, SmokefreeSGM includes a new keyword, STRESS, to address the unique psychosocial stressors of SGM smokers. Text messages were distributed to users over a 6-week period, and participants were provided with nicotine patches to aid their efforts to quit smoking. Demographic and tobacco use information was collected at baseline. Quantitative (related to engagement and usability) and qualitative (related to usability and acceptability) data was also collected at the 1-month assessment.

Results: A total of 18 SGM smokers were recruited for the pilot test. 38.9% of participants were male, 38.9% were female, and 22.2% were nonbinary. 27.8% of participants identified as gay, 11.1% as lesbians, 27.8% as bisexual females, 16.7% as bisexual males, and the remaining 16.7% as other. At baseline, two-thirds (66.7%) were moderate to highly dependent on nicotine and 44.4% had made more than five attempts to quit smoking. The average engagement rate for bidirectional text messages was 63.8%. However, the response rate to the tailored text messages (54%) was higher than the non-tailored text messages (41.9%). Nine participants completed the 1-month assessment and interview (50% retention rate). The System Usability Scale (SUS) score was 81.67 (±15.46). Furthermore, four major themes emerged from our qualitative analysis of the interviews (i.e., appreciation for the intervention, program, content, and drawbacks).

Conclusions: Findings from the pilot test of SmokefreeSGM are not only encouraging in terms of engagement, usability and acceptability, but have also informed the refinement of the program prior to launching a feasibility trial.
