Cigarette craving and stressful social interactions: The roles of state and trait social anxiety and smoking to cope.

Background: Previous research indicates that social anxiety (SA) is a risk factor for the maintenance and relapse of smoking behaviors. However, little is known about the mechanisms underlying this relationship. The current study tested the effects of state and trait levels of SA as well as smoking to cope with symptoms of SA on craving during a social stressor task in abstinent conditions.

Commentary on Kale et al. (2015): Further perspectives on the cognitive and demographic variables relevant to smoking cessation and the importance of smoking outcome expectancies.

It would be valuable to include expectancies when assessing predictors of smoking cessation attempts and the success of those outcome attempts.

Electronic Cigarette Use Among College Students: Links to Gender, Race/Ethnicity, Smoking, and Heavy Drinking.

Objective: Electronic cigarette (e-cigarette) use continues to rise, and current data regarding use of e-cigarettes among college students are needed. The purpose of this study was to examine e-cigarette use and the relation of such use with gender, race/ethnicity, traditional tobacco use, and heavy drinking.

Participants And Methods: A sample of 599 college students enrolled in General Psychology at a state university completed a self-report questionnaire.

Comparing college smokers' and dual users' expectancies towards cigarette smoking.

Background: As no agreed upon definition exists for dual use (i.e., individuals who concurrently use more than one form of tobacco), this population remains largely unstudied in the substance use literature, despite increases in smokeless tobacco use among young adults.

The development and psychometric evaluation of the Smokeless Tobacco Expectancies Scale (STES).

Expectancies regarding the effects of various psychoactive substances are important predictors of the initiation and maintenance of substance use. Although measures of outcome expectancies exist for several addictive substances, there is currently no measure to assess smokeless tobacco (ST) expectancies in an adult population. This article presents 2 studies leading to the development and psychometric evaluation of the Smokeless Tobacco Expectancies Scale (STES).

Utilizing a multimodal assessment strategy to examine variations of impulsivity among young adults engaged in co-occurring smoking and binge drinking behaviors.

Background: Smoking among young adults predicts a greater severity of alcohol use and contributes to an increased difficulty in maturing out of heavy drinking behaviors that are established during college. Moreover, research has implicated impulsivity in the initiation and maintenance of both behaviors. Much less is known, however, about potential variations of impulsivity among young adults and whether a relationship exists between this construct and abstinence from smoking.

Examining the interrelationships between social anxiety, smoking to cope, and cigarette craving.

Smokers with symptoms of social anxiety often report smoking as a way to cope with negative affect. These individuals have lower success rates when attempting cessation compared with the general population. However, there is a paucity of research examining the role of social anxiety in nicotine dependence.

Treating depressed and anxious smokers in smoking cessation programs.

Objective: Cigarette smoking is the leading cause of preventable death in the United States. In addition, smoking rates among depressed and anxious smokers are higher than in the population at large. Furthermore, treating depressed and anxious smokers effectively is particularly challenging because of their significant negative affect, dysfunctional emotional regulation, severe withdrawal symptoms, and numerous institutional barriers to successful treatment.

The effect of chewing gum flavor on the negative affect associated with tobacco abstinence among dependent cigarette smokers.

Many smokers relapse during cessation attempts due to increases in negative affect. Previous research has shown that chewing confectionary chewing gum appears to lessen the severity of acute nicotine withdrawal symptoms and help individuals who are trying to reduce smoking in part due to the flavor of the gum chewed. The current study compared the effects of three flavored gums to a No Gum Control during 48-hour cessation periods for young dependent smokers.

Depression vulnerability predicts cigarette smoking among college students: Gender and negative reinforcement expectancies as contributing factors.

This study examined the association between vulnerability to depression and smoking behavior in 1214 college students (54% female), and evaluated gender and expectancies of negative affect reduction as moderators or mediators of this relationship. Depression vulnerability predicted smoking in females, but not males. The relationship between depression vulnerability and smoking status was mediated by expectancies of negative affect reduction in females only.

Effects of sensory and behavioral substitutes following an experimentally induced stressor among abstinent smokeless tobacco users.

Despite the well-known health risks associated with smokeless tobacco use, much is unresolved with respect to effective treatment for use of this substance. The present study examined the impact of a nicotine-free smokeless tobacco substitute and confectionary chewing gum on craving, withdrawal, and anxiety among 24 smokeless tobacco users following 24 hours of nicotine abstinence and a laboratory stressor. Although chewing gum did not impact withdrawal, craving, or anxiety compared to a no-product control condition, smokeless tobacco substitute administration resulted in a reduction of withdrawal and craving levels compared to the control condition following 24 hours of abstinence.

The effect of chewing gum on self-reported nicotine withdrawal: is it the flavor, the act of chewing, or both?

A healthy alternative that has been shown to lessen the severity of nicotine withdrawal symptoms during brief periods of nicotine abstinence (e.g., 3-4 h) is confectionary chewing gum (Cohen and colleagues, 1997, 1999, & 2001).

The role of impulsivity on smoking maintenance.

In order to better understand why those higher in impulsivity experience more difficulties during smoking abstinence, the current study examined the possible mechanisms contributing to cigarette smoking relapse. Fifty dependent cigarette smokers completed measures designed to assess craving, tobacco withdrawal severity, and negative affect during 48 hours of nicotine abstinence. Using a series of multilevel models (SAS Proc Mixed Procedure), significant impulsivity x time analyses revealed differences in craving, F(2, 96) = 3.

Impulsivity and the role of smoking-related outcome expectancies among dependent college-aged cigarette smokers.

The relationship between trait-impulsivity and smoking expectancies on smoking progression in undergraduate college students was examined over a 48-hour period of smoking abstinence. Participants were forty-nine college-aged dependent cigarette smokers who completed measures designed to assess impulsivity, nicotine dependence, and smoking expectancies. Using a series of multilevel models, impulsivity by time analyses indicated significant differences in positive reinforcement expectancies, [F (2, 94)=3.

Smoking prevalence and awareness among undergraduate and health care students.

Approximately 10,000 undergraduates from 12 Texas colleges and universities and 350 health care students completed a Web-based survey assessing the prevalence and awareness of cigarette smoking. There were few differences between health care and undergraduate students on trying smoking or quitting smoking. Health care students reported lower rates of current smoking than undergraduate students, even though both groups demonstrated similar knowledge of tobacco-related health risks.

Physiological and psychological symptoms and predictors in early nicotine withdrawal.

The present study assessed the structure and intensity of the nicotine withdrawal syndrome in 30 (22 male, 8 female) heavy smokers across three experimental conditions: smoking, brief abstinence (3.5 h), and extended abstinence (18 h). Physiological variables (heart rate and blood pressure) and psychological variables (anxious and depressed mood) were examined in terms of symptom validity and as predictors of nicotine withdrawal intensity.

Appetitive nature of drug cues re-confirmed with physiological measures and the potential role of stage of change.

Rationale: Smokers report pleasant reactions to viewing cigarettes, suggesting that smoking cues may be appetitive in nature. Two studies have investigated this hypothesis through physiological assessment. The first study found that smoking cues were physiologically appetitive in nature, with dampened startle response to smoking pictures in comparison to neutral pictures.

Predictors of smoking and smokeless tobacco use in college students: a preliminary study using web-based survey methodology.

Cigarette smoking and smokeless tobacco (SLT) use are associated with numerous health hazards and economic costs, and rates of tobacco use have recently increased among young adults. In this study, the authors compared predictors of smoking and SLT use among college students (N = 21,410) from 13 Texas universities using a Web-based survey. Results revealed that sex, belonging to a fraternity or sorority, participation in intercollegiate sports, peer influences, and ethnicity predicted smoking and SLT use.

Salivary cortisol concentrations are associated with acute nicotine withdrawal.

Research has shown that smoking commercial cigarettes results in slight elevations in cortisol levels relative to smoking nicotine-free cigarettes. It is not clear however, whether cortisol concentrations are associated with nicotine withdrawal symptoms among regular cigarette smokers. Nicotine withdrawal symptoms resemble a stress response, and may therefore contribute to cortisol production.

Attachment and depression differentially influence nicotine dependence among male and female undergraduates: a preliminary study.

The authors surveyed a convenience sample of 208 undergraduate students who reported that they smoked cigarettes. The primary hypothesis they tested was whether gender predicted nicotine dependence. They further tested whether depression and attachment would mediate or moderate this relationship.

Negative affect combines with smoking outcome expectancies to predict smoking behavior over time.

The present study examined whether the tendency to experience negative affective states combines with smoking outcome expectancies to predict smoking behavior over time. Participants were 121 young adults and resource people recruited from 3 alcohol and drug treatment programs and through community advertisements. Each participant completed 3 interviews over a 4-year period.

Effect of non-nicotinic moist snuff replacement and lobeline on withdrawal symptoms during 48-h smokeless tobacco deprivation.

The present study investigated the effects of two herbal components (BACCOFF and DIPSTOP) of a commercially available smokeless tobacco treatment program for reducing subjective withdrawal symptoms during deprivation. One component, BACCOFF, is a non-nicotinic chew. The second component, DIPSTOP, is a liquid containing the alkaloid lobeline, which to some extent mimics peripheral nicotinic effects.
