简要总结
Participants will complete this study remotely, either at home or at their preferred location using an online platform. The investigators propose to test the effects of a mindfulness training [MT: Headspace] intervention compared to a time and attention psycho-education control [control: TedTalks] among N=200 adult smokers of a nicotine product. Previous studies suggest that mindfulness training may be beneficial in reducing craving during tobacco abstinence. During the study, participants will complete baseline questionnaires, followed by two weeks of daily MT or control training and self-report on questionnaires assessing affect, cognition, and smoking behavior using Ecological Momentary Assessment (EMA) for remote data capture. Following this two weeks of training, participants will complete a smoking quit attempt and complete daily EMA questionnaires for two weeks. The first day of the smoking quit attempt will include a remote Zoom video session following overnight smoking abstinence. During this session the participants will complete a remote stressor task (Trier Social Stress Test, TSST), and the investigators will collect EMA data on affect and smoking behavior before and after the TSST. One month after the start of the quit attempt, participants will complete a phone call as a follow-up to assess smoking behavior over the previous 30 days, and to complete a debriefing. Study objectives are to test the effect of MT on: (1) smoking lapses during the follow-up periods; and (2) stress (affect, smoking urge, withdrawal symptoms) during the TSST.

盲法说明
The investigators and majority of study staff are blinded. The only individuals who are unblinded to a participant's conditions do not conduct data collection nor interact with participants beyond assigning participants to a condition and explaining the protocol for MT or control app training.
Participants are aware of their condition, but do not know that the protocol is being measured as the variable of interest, nor that other participants are assigned to different conditions.

研究组 & 干预措施
Mindfulness
Participants in the experimental arm are asked to use a mindfulness smartphone application called Headspace. Headspace offers pre-recorded introductory mindfulness meditation audio instructions guided by experienced meditation teachers. Study participants are instructed to voluntarily complete 10 minutes of Headspace twice per day for 14 days, a total recommended dose of 280 minutes. Mindfulness practice begins the day after the baseline interview (i.e., intervention day 1). Participants are encouraged to listen at two separate times each day to support habit formation and to maximize daily exposure with low time burden. As participants have minimal prior experience with mindfulness attributed to the study eligibility criteria, all recommended trainings are at the beginner level. Participants have access to all sessions offered and are not restricted to a particular sequence.
干预措施: Headspace (Behavioral)
Psychoeducation
Participants in the psychoeducation arm listen to TEDTalks audio recordings by experts on field-specific topics. Study participants are instructed to complete 10 minutes of TEDTalks twice per day for 14 days. Sessions were selected by the study team to be of interest to the public yet not include content on meditation, smoking, or content appearing to cue behavior change associated with smoking. Like the Mindfulness condition, participants in the Psychoeducation condition begin the practice the day after the baseline interview. Participants are told to listen at two separate times each day to maximize daily exposure with low time burden. Additionally, participants are instructed to listen with "full mindful attention and return attention to the audio when attention drifts" to match the Mindfulness instruction and emphasize the importance of sustaining attention for each 10-minute period. Participants have access to all sessions offered and are not restricted to a particular sequence.
干预措施: TEDTalk (Behavioral)
结局指标
主要结局
Smoking Cessation Behavior at 30 days
时间窗: 30 days after start of quit attempt
7-day point prevalence abstinence (i.e., no cigarettes smoked in the previous 7 days). 0=did not smoke; 1=smoked at least one cigarette.
Smoking Cessation Behavior at 14 days
时间窗: 14 days after start of quit attempt
7-day point prevalence abstinence (i.e., no cigarettes smoked in the previous 7 days). 0=did not smoke; 1=smoked at least one cigarette.
