Objective: College students use electronic nicotine delivery systems (ENDS) more often than any other US demographic group. In a novel application of the acquired preparedness model, we examined how proximal (e.g., cognitions) and distal (e.g., dispositional) influences accounted for ENDS use and dependence. Participants: Undergraduates (N = 1075;…

Purpose of this study was to examine the internet addiction levels of university students under various variables. In the study, the level of internet addiction was compared with variables such as gender, physical exercise patterns, accommodation preference, marital status of the family, cigarette and alcohol consumption, grade point average,…

The aim of this study was to identify the association between type D personality and smoking cessation among high school students who had participated in a stop smoking program. From 27 high schools, we recruited 279 smoking students who had participated in a stop smoking program between May 29, 2015, and January 25, 2016. About 26.5% of…

Health warning labels (HWLs) on cigarette packs that use strong fear appeals may evoke defensive responses including acts of disparaging the warnings. Whether warning disparagement undermines HWL effectiveness remains unclear. We assessed correlates of one type of HWL disparagement and its association with subsequent cessation attempts.…

Introduction: E-cigarette use remains a controversial topic in public health and medicine. Historically, cigarette smoking was identified as a gateway to marijuana use among adolescents. Recently, the prevalence of adolescent cigarette smoking has declined, but that of e-cigarette use continues to increase. As e-cigarettes eclipse cigarettes among…

Understanding the factors that make college students more likely to drink alcohol and smoke cigarettes is key to developing effective interventions in order to reduce these behaviors. This study sought to understand entering college students' intentions to engage in smoking and drinking behavior by examining the cognitive accessibility (ease of…

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…

It is still under debate whether the reported effects of opioid maintenance therapy (OMT) on child behaviour are a direct effect of prenatal exposure, or whether other factors are involved. This prospective cohort study investigated three models: the teratogenic risk model, the maternal risk model, and a combined risk model in a group of 35…

Previous research has shown that the development of alcohol and tobacco dependence is linked and that both are influenced by environmental and intrapersonal factors, many of which likely interact over the life course. The present study examines the effects of general and alcohol- and tobacco-specific environmental influences in the family of…

Objective: Based on conceptual models of addiction and affect regulation, this study examined the mechanisms linking current major depressive syndrome (MDS) and anxiety syndrome (AS) to postpartum smoking relapse. Method: Data were collected in a randomized clinical trial from 251 women who quit smoking during pregnancy. Simple and multiple…

The relationship between nicotine dependence and DSM-IV psychiatric disorders in 1,039 adolescents is examined. Findings revealed that psychiatric disorders most usually predicted the onset of the first basis of nicotine dependence while nicotine dependence does not appear to have an influence on the onset of psychiatric disorders. Other…

Relative reinforcing efficacy refers to the behavior-strengthening or maintaining property of a reinforcer when compared to that of another reinforcer. Traditional measures of relative reinforcing efficacy sometimes have led to discordant results across and within studies. By contrast, previous investigations have found traditional measures to be…
