Young adulthood is the developmental period when cigarette smoking becomes more entrenched, with dramatic increases in intensity occurring after age 18 (Hammond, 2005). In order for us to confinue to make gains in reducing rates of cigarette smoking, we need to address the problem of smoking among young adults. This project will use Ecological Momentary Assessments (EMA) to gather real-fime, naturalisfic self reports of young adults'daily experiences and smoking behavior to examine how the immediate situation (proximal context) in which smoking occurs, along with the individual's subjecfive reactions to those experiences, varies by smoking level and influences future smoking behavior. This proposed project builds on several of our compelling findings to date with our current program project. These findings include: a) Mood just prior to smoking differs significantly from random, background times, such that when adolescents smoke, they feel less posifive and more negafive than other fimes. b) Following smoking, adolescents experience a significant relief of negafive affect and boost in posifive affect, c) Importantly, this change in affect predicts smoking trajectory - adolescents who belong to the trajectory with the lowest level of use and who do not escalate in their smoking derived the least amount of posifive affecfive change following smoking;that is, these youth did not experience the """"""""boost"""""""" following smoking, d) Mood variability, and not just overall level of mood, may be important in predicfing escalafion. e) Adolescents experience subjective aspects of withdrawal and dependence, even at relafively low levels of smoking. And f) Conjoint alcohol use and smoking may diminish the subjecfive mood boosts from smoking, although social context may be an important moderator. As we follow participants into young adulthood and as their smoking progresses, we will focus specifically on affective prompts and consequences to smoking, tracking of withdrawal symptoms, including new measures of attenfion, craving, as well as safisfacfion with smoking, and the influence of alcohol and social contexts on smoking. This proposed project presents a unique opportunity to track and examine the development of dependence from adolescence through young adulthood. Thus, this project is well posifioned to make a unique contribution to our understanding of the development of smoking patterns and nicotine dependence.
In order for us to confinue to make gains in reducing rates of cigarette smoking, we need to address the problem of smoking among young adults, the age group with the highest rates of smoking. This project will use Ecological Momentary Assessments (EMA) to gather real-time, naturalistic self-reports of young adults daily experiences and smoking behavior to examine how the immediate situafion (proximal context) in which smoking occurs, along with the individual's subjecfive reacfions to those experiences, varies by smoking level and influences future smoking behavior. This project presents a unique opportunity to track and examine the development of dependence from adolescence through young adulthood, and as such, should help in developing future intervenfions.
