Brief summary
The primary goal of the study is to evaluate the use of a new smart phone application in preventing relapse to smoking among people with PTSD. The technology intervention will combine a mobile system to reward non-smoking, smoking cessation counseling, smoking cessation medications, and use of the smart phone app. The primary aim is to evaluate how effective this intervention is in preventing smoking relapse compared to another intervention that does not include the app.
Detailed description
The primary goal of the current study will be to evaluate the use of a new smart phone application (app; Stay Quit Coach) in preventing relapse to smoking among individuals with PTSD. The enhanced technology intervention will combine mobile contingency management (mCM), guideline-based smoking cessation counseling, bupropion and nicotine replacement therapy (NRT), and use of the Stay Quit Coach. For this study, we will propose a clinical trial with a two-group design in which 20 smokers with PTSD will be randomized to either: QUIT4EVER, an intervention that combines guideline-based smoking cessation counseling, bupropion and NRT, mCM and Stay Quit Coach. COMBINED CONTACT CONTROL (CCC) an intervention that is identical to QUIT4EVER except Stay Quit Coach will not be included. The CCC controls for compensation, monitoring, time and attention effects. Specific aims are to: AIM 1: evaluate the efficacy of QUIT4EVER on rates of abstinence from cigarettes (assessed with multiple measures including bioverified abstinence) during short and long term abstinence (measured at 3 and 6 months). Hypothesis 1: QUIT4EVER will be associated with increased long term abstinence (self-reported and bio-verified prolonged abstinence at the 3 and 6 month follow-up). AIM 2: assess the impact of QUIT4EVER on counseling treatment completion and medication adherence. Hypothesis 2. Increased abstinence associated with QUIT4EVER will be partially mediated by increased telephone counseling treatment completion and greater medication adherence. AIM 3: calculate the relative cost-effectiveness of the QUIT4EVER intervention in quality adjusted life years (QALY). Hypothesis 3: QUIT4EVER based treatment will result in greater cost-effectiveness compared to the control condition as measured by the incremental cost-effectiveness ratio. Overall, results of this study could lead to a highly efficient, effective, and easily disseminated treatment method for reducing smoking among smokers with PTSD and other psychiatric disorders.
Interventions
DRUGBupropion
All participants who are medically eligible will be prescribed bupropion, which they will start two weeks prior to their quit day. Dosage will be 150 mg/daily for days 1-7 and 300 mg/daily (administered in two daily doses) until the 3-month follow-up.
DRUGnicotine replacement therapy
Participants will be prescribed NRT patch and one nicotine rescue method (e.g., nicotine gum, lozenge, inhaler) for use during the post-quit phase of the study. Participants will be given the choice between nicotine gum, nicotine inhaler, or nicotine nasal spray, and will be instructed to use the rescue method as needed to reduce cigarette cravings
OTHERSmoking cessation counseling
Participants will receive four 20-minute smoking cessation counseling sessions and a participant manual. The four sessions are based on standard cognitive-behavioral therapy techniques shown to be efficacious for smoking cessation.
BEHAVIORALmobile contingency management
Participants will be asked to provide video recordings of themselves taking carbon monoxide readings in order to confirm smoking abstinence. Participants are asked to upload these videos to the study's secured server, and are provided monetary reward for videos that suggest smoking abstinence.
OTHERStay Quit Coach
Stay Quit Coach is a smart phone application that serves as a source of readily available support and information for adults who are already in treatment to quit smoking and to help them stay quit after treatment. The app guides user in creating tailored plans that include their personal reasons for quitting, interactive tools to help users cope with urges to smoke, motivational messages, support contacts to help users stay smoke free and how to address lapses. Participants assigned to this condition will be asked to use Stay Quit Coach from Session 2 through the 6-month follow-up.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| smoking, self-report | 6 months follow-up | Participants' self-report of smoking in the past seven days will be measured at the end of the treatment intervention, and at 3 and 6-month follow-up contacts. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| saliva cotinine | 6 months | For participants reporting smoking abstinence at 3 and 6-months post treatment follow-ups, we will bio-verify smoking abstinence by collecting saliva samples that will be used to determine salivary cotinine levels. |
