Egyéb: Kwit smartphone app

The Kwit smartphone app combines several popular features of tobacco cessation apps, including game-like features (e.g., unlocking achievement milestones for completing cessation-related tasks), useful statistics (e.g., money saved), and an ability to share progress with friends. Users can actively engage with the app to track cravings or view progress, such as life expectancy gained. A passive component notifies users when milestones have been achieved, e.g., when blood no longer contains nicotine. Motivational messages can be actively requested at any time; they can also appear unsolicited, as when the user logs cravings.

Helpfulness, frequency of use, and ease of use of the intervention smartphone app

Assessment of feasibility: Two follow-up surveys will be administered: the first, 1-month after recruitment,and the second, 3 months after recruitment. Surveys will be administered in-person. Specific questions will be asked to rate the Kwit smartphone application's feasibility, based on a combination of helpfulness, frequency of use, and ease of use. Frustrations and helpful aspects of the application will be assesses qualitatively.

1. How helpful was the Kwit app?
2. Was the app easy to use?

3. Was it frustrating to use?

   Responses for 1-3 will be limited to Very helpful, Somewhat helpful, Neutral, Not very helpful, Not at all helpful

4. What, if anything, was helpful about the app? What, if anything, was not helpful about the app?

Each of these responses (Q1-3) will be combined to report a single overall feasibility value. Qualitative data (Q4) will be used to modify scores as needed.

Cessation (self-report)

Descriptive statistics will be used to assess cessation outcomes. The information will be obtained via two follow-up surveys (1 month and 3 months after recruitment), with specific questions pertaining to the level of participant smoking as well as their confidence levels on maintaining cessation.

1. Since you joined the study, have you smoked a cigarette (even a puff)?
2. How soon after you joined the study did you smoke your first cigarette, even a puff?
3. In the past 30 days, on how many days did you smoke (even a puff)?
4. (On the days you smoked) how many cigarettes on average did you smoke (even a puff)?
5. In the past 7 days, have you smoked a cigarette, even a puff?
6. How confident are you that you will be able to stay quit?

The overall assessment of cessation will be primarily based on the 7-day item.

Cessation (bio-chemical)

Cessation will also be verified by a breath analysis monitor. The information will be obtained during each follow-up. Biochemical verification will be based on a 10 COppm cutoff to determine whether or not the participant has successfully quit tobacco.
