简要总结
This research study aims to develop a cognitive dissonance-based mobile app for smoking cessation (Support2Quit) and test the efficacy of the app with 500 adult smokers who express a desire to quit smoking.
详细描述
This research project will evaluate the Support2Quit mobile app for smoking cessation by having 500 daily adult smokers recruited through social media and randomized to either the Support2Quit app or an app that has similar content but no tasks for inducing cognitive dissonance among participants. Outcomes will be measured at 1- and 3-months post-baseline and will include quit attempts, number of days without smoking (smoke free days), and changes in smoking attitudes and behavior, and smoking abstinence. Usability data, system log data on program use, and participant satisfaction data will also be analyzed.
The researchers hypothesize that individuals using the cognitive dissonance intervention (CDI) will show greater increases in quit attempts, smoke free days, quit rates, and positive smoking attitudes and behaviors than individuals in the active comparison condition. The researchers will test whether gender, smoking dependence, readiness to quit, previous quit attempts, age of smoking initiation, and socio-economic status moderate intervention effects on smoking outcomes.

结局指标
主要结局
Number of Participants With Cigarette Abstinence
时间窗: 1-month and 3-month follow-up
Based on 1-item that asked "In the past 7 days, have you smoked any cigarettes?". The variable is coded 1 if they the participants indicated they did not smoke any cigarettes otherwise coded 0. A value of 1 = abstinence and 0 = not abstinent.
Fagerstrom Tobacco Dependence Scale
时间窗: Baseline, 1-month follow-up, 3-month follow-up
This is a 6 item measure of tobacco dependence and response options are a mix of ordered categorical and dichotomous items. Item 1 "How many cigarettes per day to you smoke?" (0 = less than 10 cigarettes a day, 3 = 31 or more cigarettes a day). Item 2 "How soon after you wake do you smoke your first cigarette (0 = after 60 minutes, 3 = within 5 minutes). Item 3 "Is it hard to keep from smoking in places where it is prohibited (1 = yes, 0 = no). Item 4 "Which cigarette would you hate to give up most (1 = the first in the morning, 0 = any other). Item 5 "Do you smoke more cigarettes during the first 2 hours of the day compared to the rest of the day (1 = yes, 0 = no). Item 6 "Do you smoke when you are so ill you are in bed?" (1 = yes, 0 = no). A total sum score is computed and can range from 0 to 10 points with higher scores indicating higher levels of tobacco dependence.
Number of Participants With Reduction in Number of Cigarettes Smoked Per Day
时间窗: 1-month and 3-month follow-up
Represents whether or not (1 = yes, 0 = no) a reduction of cigarettes smoked per day is reported from the baseline assessment. A higher score indicates a reduction in cigarettes smoked.
Number of Participants With Reduction in the Number of Cigarettes Smoked Per Day and Reduced to 0-5 Cigarettes
时间窗: 1-month and 3-month follow-up
Represents whether or not (1 = yes, 0 = no) a reduction of cigarettes smoked per day is reported from the baseline assessment and is the number of daily cigarettes in 0-5 per day. A higher score indicates a reduction in cigarettes smoked per day and the number smoked is 5 or less.
