Brief summary
Due to the pandemic, this study was modified from a randomized clinical trial to test the feasibility, initial efficacy, and mechanisms of action of our PTSC-S intervention to a feasibility and acceptability test of our intervention when delivered via telehealth in a single group, within-subjects design.
Detailed description
The investigators will test the feasibility and acceptability of a telehealth-delivered treatment designed to help smokers with serious mental illness to quit using a therapy approach focused on increasing task persistence. We will provide free, weekly individual telehealth video counseling sessions for 8 weeks and 10-weeks' worth of the nicotine transdermal patch (an FDA-approved smoking cessation product available over the counter). All sessions will be video recorded for treatment integrity and supervision. The investigators hypothesize that 1) the PTSC-S intervention will be acceptable to participants, and the study will be feasible to conduct. We will report prolonged and point prevalence abstinence rates at end-of-counseling and at 3-month follow-up (CO verified \<8ppm).
Interventions

| Acceptability 1: Participant Rating of Usefulness of Intervention | 3-months post quit date (approximately 4-months after baseline assessment) | After each session, participants (N=33) provided a 1-7 rating of how easy to understand and how helpful the intervention was.

| Acceptability 3: Participant Rating of Treatment Length / Timing of Target Quit-Date | 3-months post quit date (approximately 4 months after baseline assessment) | We asked participants how acceptable the placement of the target quit date was to participants (i.e., it was scheduled for session 4). We report the percentage of participants who responded that the quit date was too soon, too late, or just about right. |
| Feasibility 1: Number of Participants Contacted at 3 Months Post-Quite Date | 3-months post quit date (approximately 4 months after baseline assessment) | We will calculate follow-up rates to determine if they meet our goal of 80% follow-up rates at the 3-month follow-up. |
