The study team will conduct a Multisite Randomized Controlled Trial to evaluate the advantages and disadvantages of two approaches for quitting smoking among people with serious mental illness (SMI). The study will compare a novel app tailored to people with SMI, Quit on the Go, to a standard of care smoking cessation intervention. We will test the effectiveness of the Quit on the Go app, an intervention that has demonstrated feasibility and acceptability in the target population, as a tool for smoking cessation in people with SMI. Participants with SMI will be recruited across 3 sites (Duke University, Univ. at Buffalo, and Wake Forest University).
Smoking tobacco shortens the lifespan of adults with serious mental illness by 25 years and contributes to 317 billion dollar expenditures in healthcare, indirect loss of earnings and disability benefits. Determining whether it is possible to deliver more effective and wider reaching smoking cessation interventions to individuals with serious mental illness is a high priority. Smartphone apps are a wide-reaching technology that could provide individuals with serious mental illness the necessary skills for quitting. However, our research has shown that apps developed for the general public have inadequate levels usability and engagement in people with serious mental illness.
In a previous pilot trial of a tailored smoking cessation app for people with serious mental illness, Learn to Quit (NCT03069482), we identified successful recruitment and retention methods for smokers with SMI, demonstrated a 4-fold increase in objectively measured interactions of the novel app, obtained promising cessation rates for the experimental app (12% for Quit on the Go formerly "Learn to Quit" versus 3% for NCI QuitGuide), and identified a reliable methodological approach to conduct a fully-powered randomized controlled trial.
Based on this pilot work, we plan to conduct a clinical trial to test this new model in a diverse and representative sample of the SMI population. Specifically, the proposed trial will test whether a tailored smoking cessation app for people with serious mental illness, Quit on the Go, results in higher levels of smoking abstinence compared to a standard of care intervention for this psychiatric population, Brief Advice. Both interventions will receive combined nicotine replacement therapy. The second aim of this trial is to test a mechanistic model of app efficacy by examining mediators of app engagement and treatment outcomes. Finally, the trial will evaluate the cost-effectiveness of these interventions to inform public health policy regard the use of mHealth in this population.
In a multi-site, two-arm randomized controlled trial, 450 individuals with serious mental illness will be randomly assigned to one of two conditions. In the experimental condition, participants will use the Quit on the Go app. In the comparator condition, participants will receive Brief Advice for smoking cessation. Participants in both conditions will receive combined Nicotine Replacement Therapy (standard dosing of nicotine patch plus 5 week course of nicotine gums). Study duration will be 6 months, with 3 follow-up appointments at 1-month, 3-month, and 6-months. Our proposed methods are appropriate given our established procedures during our pilot trial regard to participant assignment, delivery of interventions, data collection and analysis (NCT03069482).
The proposed study meets NIDA's major programmatic priorities of using innovative technologies (e.g., smartphones) and integrating behavioral and pharmacological interventions to improve substance use treatment and outcomes (NOT-DA-10-019). The proposal addresses a serious problem -- high smoking rates in people with SMI -- in a high priority, high cost population, by delivering a novel behavioral intervention for smoking cessation in "real-world" settings. If shown to be effective, the proposed intervention will provide a new model for delivering inexpensive, widely accessible smoking cessation interventions in adults with SMI.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| "Quit on the Go" (formerly "Learn to Quit") | Experimental | A smartphone app developed by the research team designed for people with serious mental illness, that provides Acceptance and Commitment Therapy skills to address (a) smoking cessation and (b) mental health symptoms. This app intervention is combined with an 8-week course of nicotine replacement therapy (NRT) patches and a 5-10 week course of NRT gum (or Nicotine Lozenges if unable to use gum). Participants also receive technical smartphone coaching for the first 4 weeks of the study. |
|
| Brief Advice (Standard of Care) | Other | Brief Advice and Combined Nicotine Replacement Therapy (patches and gum or lozenges) has been recommended by the US Clinical Practice Guidelines for patients with psychiatric illness. Brief Advice will consist of 20 minutes of guidance about the use of nicotine replacement therapy, and strategies to initiate and maintain a quit attempt. The intervention is combined with an 8-week course of nicotine replacement therapy (NRT) patches and a 5-10 week course of NRT gum (or Nicotine Lozenges if unable to use gum). |

| Measure | Description | Time Frame |
|---|---|---|
| CO-verified 7-day point-prevalence abstinence at 6-month follow-up | Abstinence is determined by a self-report of not smoking any tobacco product for greater than or equal to 7 days prior to Week 24 and biochemically verified by an expired carbon monoxide breath test reading of < 5 ppm at Week 24. If the participant does not meet both criteria, they are not considered abstinent. As per convention, participants are assumed to be smoking if they report smoking at the time-point, cannot be reached to provide data at the time-point, fail to provide a breath sample at the time-point, or provide a breath sample at the time-point that is greater than or equal to 5 ppm. | 6 month follow-up |

| Brief advice | Behavioral | Brief Advice will consist of 20 minutes of guidance about the use of nicotine replacement therapy, and strategies to initiate and maintain a quit attempt. |
|
| Nicotine patch | Drug | All participants will receive an 8-week course of transdermal nicotine patches. The first 4 weeks of use will be 21mg/24 hours, followed by 2 weeks of 14mg/24 hours patches, and finally 2 weeks of 7mg/24 hours patches. |
