Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Chronic cigarette smoking habits often begin in adolescence or early adulthood. 98% of cigarette smokers try their first cigarette before the age of 26. Thus, young adult smokers represent an important target for early smoking cessation intervention. This study tests two interventions designed to increase motivation to quit and decrease smoking behavior. These interventions include: an expectancy challenge approach, which aims to increase negative beliefs about the consequences of smoking; and a behavioral economics approach, which encourages participants to substitute non-smoking behaviors that may still provide reinforcement similar to reinforcement derived from smoking a cigarette.
