Iceland has witnessed a dramatic decline in adolescent substance use that may be partly the result of efforts related to the Icelandic prevention model (IPM). We sought to test risk and protective factor assumptions of the IPM using a prospective cohort study with 12 months separating baseline from follow-up. Participants were students in grades 8…

Smoking is a worldwide problem that threatens people's health. The average age of smokers has decreased with each passing day. Thus, studies focusing on preventing children or teenagers from starting smoking or studies aiming to help people quit smoking are one of the most effective ways of the fight against smoking. In order to prevent smoking…

Students with multiple health risk behaviors (HRB) have increased amount of research attention. The study aimed to examine the multiple health behaviors and whether these behaviors differ by demographic characteristics and social factors in a 1-year follow-up study among 1,989 students. All the measures were from the Youth Risk Behavior…

Adolescence is a vulnerable period for the initiation and peak of many harmful risk-taking behaviors such as smoking, which is among the most addictive and deadliest behaviors. Generic metatheories like the theory of triadic influence (TTI) suggest that interrelated risk factors across multiple domains (i.e., intrapersonal and…

Developed a simulation model to predict the effects of policies for reducing adolescent smoking initiation. The model projected numbers of smokers, never smokers, and ex-smokers by age, sex, and race/ethnicity and effects of reductions in youth initiation. Results predicted that even if tobacco policies eliminated youth initiation, the number of…

Objective: To identify individual and institutional risks and protections for hookah and cigarette smoking among African American (AA) college students. Participants: AA college students (N = 1,402; mean age = 20, range = 18-24 years; 75% female) who completed the Fall 2012 American College Health Association--National College Health Assessment…

Our longitudinal, qualitative study with 29 pregnant adolescents who smoke used a Participatory Action Research (PAR) approach to understand experiences and the function of tobacco through pregnancy to 6 months postpartum. The young women described complex lives of overlapping oppressions interspersed with expressions of resistance; these were…

Causal inference under treatment interference is a challenging but important problem. Past studies usually make strong assumptions on the structure of treatment interference in order to estimate causal treatment effects while accounting for the effect of treatment interference. In this article, we view treatment diffusion as a concrete form of…

Based on social skills and operant behavioral perspectives, an Environment and Skills Model of smoking acquisition and prevention is proposed. This model involves an integrated examination of the antecedents, behaviors, and consequences of smoking. The importance of the "consequence end" of this three-term contingency is discussed.

Objective: Secondhand smoke exposure is associated with asthma onset and exacerbation. Latino children have higher rates of asthma morbidity than other groups. The current study compared the effectiveness of a newly developed smoking cessation treatment with existing clinical guidelines for smoking cessation. Method: Latino caregivers who smoked…

This is a cross-sectional study conducted to examine the associations between the composition of friendship networks and health-related behaviors of 988 adolescents (11-18 years old) from Colombia. Participants were asked to self-report behaviors and to nominate their best friends. "Egocentric network analysis" (i.e., analysis of…

Background: Cigarette use is a public health issue and juvenile offenders are at risk for engagement in substance use. Attention deficit hyperactivity disorder (ADHD) has been linked to elevated risk for cigarette use and juvenile offenders are at elevated risk for mental health issues. Objectives: To elucidate general patterns of development of…

Objective: Animal studies have shown that when nicotine is administered in the presence of other animals (as compared with alone), it is more rewarding. As a human analogue to these studies, rewards associated with designated smoking areas on university campuses were examined, since these areas promote using nicotine in the presence of others.…

Examines the relationships of smoking-related beliefs, attitudes, and smoking status, with a focus on experimental smoking. Survey results of 9,774 respondents suggest that attitude and belief variables can adequately predict smoking stages of adolescents as defined by the stage model of smoking acquisition. Argues that intervention with…

Background: Personal smoke-free policies (home and vehicle) reduce secondhand smoke exposure, improve health, and increase quitting among smokers. Overall, 83.0% and 78.1% of Americans report smoke-free homes and vehicles, respectively. However, little is known about such policies among 2-year community college (CC) students, who represent a…
