NCT03912194

Brief Summary

Smoking remains the single most preventable cause of morbidity and mortality in the United States, accounting for approximately half a million deaths every year. The current study will investigate the efficacy and mechanisms of change of a novel smoking cessation intervention. The current study will thus provide essential information regarding a treatment that has the potential to enhance the efficacy of existing smoking cessation interventions, thereby having a beneficial impact on the public health of the United States.

Outcome Measures

Primary Outcomes (3)

  • Smoking cessation as evaluated by self-reported, biochemically-confirmed seven-day point-prevalence abstinence

    Self reported abstinence from smoking ("no smoking, not even a puff) in the past seven days, biochemically confirmed by a breath carbon monoxide reading of 3 or less

    1 month after end-of-treatment

  • Smoking cessation as evaluated by self-reported, biochemically-confirmed seven-day point-prevalence abstinence

    Self reported abstinence from smoking ("no smoking, not even a puff) in the past seven days, biochemically confirmed by a breath carbon monoxide reading of 3 or less

    3 months after end-of-treatment

  • Smoking cessation as evaluated by self-reported, biochemically-confirmed seven-day point-prevalence abstinence

    Self reported abstinence from smoking ("no smoking, not even a puff) in the past seven days, biochemically confirmed by a breath carbon monoxide reading of 3 or less

    6 months after end-of-treatment

Secondary Outcomes (21)

  • Cessation milestones as determined by the Timeline Followback Interview
