简要总结
This trial studies how well Quit4Health intervention works in supporting smoking cessation and preventing smoking initiation in young adults. Quit4Health intervention may help young adults learn more about the risks of tobacco use and may help them to quit smoking.
详细描述
PRIMARY OBJECTIVES:
I. To evaluate whether smokers randomized to Quit4Health are more likely to quit smoking and remain tobacco-free at 6 months than subjects randomized to the education only control group.
II. To evaluate whether non-smokers who are randomized to Quit4Health are less likely to initiate tobacco usage and remain tobacco-free at 6 months than non-smokers randomized to the education only control group.
SECONDARY OBJECTIVES:
I. To evaluate whether well-established predictors of susceptibility and barriers to cessation (e.g. self-efficacy, knowledge about associated risks, normative beliefs, attitudes, resistance skills, peer pressure) and recently identified predictors of tobacco use (e.g., depression, nicotine dependence, alcohol use, risk-taking propensity) will mediate the effect of the intervention on both onset (for non-smokers) and cessation (for smokers) of tobacco use.

结局指标
主要结局
Abstinence from tobacco
时间窗: At 6 months
Any abstinence is defined as "subjective reports of abstinence from tobacco for at least 24 hours or more in the past 30 days", the 7-day point prevalence of abstinence at follow-ups will be verified by measurement of saliva cotinine. The primary analysis will compare the abstinence rates at 6 months in the control and treatment group using a 2-sample test of proportion for all smokers. A secondary analysis will involve a simple post-test analysis among smokers using logistic regression.
Susceptibility to tobacco initiation
时间窗: At 6 months
Will assess susceptibility to smoking using the measure proposed by Pierce and colleagues. Will employ similar analytic methods as in primary objective 1 to evaluate the prevalence of susceptibility at the 6-month follow-up in subjects randomized to the experimental intervention condition with respect to subjects assigned to the control condition.
次要结局
- Mediation effect of predictors of smoking and recently identified predictors of tobacco use(Up to 6 months)
- Behavior modification(Up to 6 months)
