Immediate effects of cigarette smoking as related to different smoking habits.

A questionnaire concerning interactions between the need to smoke and the external situation was used to select 8 "low-arousal smokers" and 8 "high-arousal amokers." The former were smokers who generally experienced their strongest need to smoke in low-arousal situations, characterized by e.g., monotony or boredom, while the latter experienced their strongest need to smoke in high-arousal situations, characterized by, e.g., anxiety or excitement. Members of each group were examined under smoking and nonsmoking conditions in a low-arousal situation, i.e., performing a vigilance-type sensorimotor task, and in a high-arousal situation, i.e., performing a complex sensorimotor task. It was shown that the two groups reacted differently to smoking in the two situations. In low-arousal smokers performance and general well-being were favourably affected by smoking in the low-arousal situation only. Conversely, performance and well-bing of the high-arousal smokers were enhanced by smoking in the high-arousal situation only.     

Prevalence and behavioural risk factors of light or moderate and heavy cigarette smoking in 32 countries

The aim of this study was to predict the prevalence of light or moderate and heavy smoking from lifestyle behavioural risk factors among South African adults compared to others from 31 countries around the world. Secondary data from 53 391 adults who completed the International Social Survey Program (ISSP), 2011–2013, Health and Health Care Module were accessed for this study (South Africans, N = 3 004). Findings from multinomial logistic regression with adjustment for personal factors (e.g. physical and psychological well-being variables) were used to explain a significant proportion of both light or moderate smoking and heavy smoking among South African adults as well as adults from the other countries. Specifically, lifestyle factors of being underweight and overweight or obese were negatively associated with light or moderate smoking, but body mass index (BMI) weight status was not associated with heavy smoking. Smoking interventions should target modifiable lifestyle factors to prevent risk for light or moderate smoking and heavy smoking.     

Behavior analysis of cigarette smoking

Patterns of cigarette smoking, treated as series of discrete events in time, were investigated with a variety of quantitative techniques designed to characterize individual subject smoking series and to illuminate the relationship between cigarette smoking and environmental events. Data were collected from a total of 35 subjects who were either participants in residential laboratory studies or in a smoking cessation program. Cigarette smoking events were found to be fairly irregularly distributed with respect to time within individual subject series. However, strong dependencies were found between the occurrence in time of individual acts of cigarette smoking and coffee drinking. In addition, the distribution and frequency of smoking events throughout one-hour activity sequences were found to be dependent upon the nature of the activity, and the temporal scheduling of activities was found to affect several quantitative indices of smoking patterns.     

Aversive cigarette smoking with an habitual, excessive smoker.

A 39-yr.-old patient was exposed to aversive cigarette smoking consisting of rapid smoking, handling of cigarette litter, and warm smoky air for 6 wk. He reduced from a baseline of 140 cigarettes per day to less than 20 at end of treatment. Follow-ups at 1, 2, 3, 6, and 9 mo. indicated a smoking rate of approximately 25% of baseline.     

Preventing smoking: evaluating the potential effectiveness of cigarette warnings.

We examined the potential effectiveness of U.S. government cigarette warnings in preventing adolescent smoking. In Study 1, 112 seventh graders rated the effectiveness of four currently required warnings and four possible other warnings and answered questions about the meaning of certain words in the warnings. In Study 2, 115 seventh graders attempted to recall the four current warnings; in Study 3, 103 eighth and ninth graders read all eight warnings one day and tried to recall them the next day. In Study 4, 25 seventh graders participated in a focus session in which they discussed the effectiveness of each of the eight warnings. The results of the studies showed that the four different evaluation strategies had convergent validity and that two current warnings and two proposed warnings are significantly more potentially effective than the other two current warnings. Our results also provided information about why some warnings are more potentially effective than others.     

Effects of cigarette smoking on lexical decision-making

10 habitual smokers, aged 19-25 yr., were randomly assigned to smoke either a very low nicotine "Placebo" cigarette (.05-mg nicotine delivery as estimated by the FTC method) or a Nicotine cigarette (.7-mg estimated nicotine delivery). Each participant was asked to abstain from smoking for 4 to 7 hr. prior to testing. After completing a presmoking test of lexical decision-making, participants smoked either a Nicotine or Placebo cigarette and were then retested for reaction times and accuracy on the lexical decision test. When presented the most difficult lexical decisions, participants responded significantly faster after smoking a Nicotine cigarette than they did before smoking; smoking a Placebo cigarette did not affect reaction times. Response accuracy was unaffected by smoking either kind of cigarette. These results suggest that smoking a nicotine cigarette may improve attention or memory retrieval after several hours of smoking abstinence.     

Personality dimensions and cigarette smoking behavior in polish and U.S. adolescents

Abstract

To contribute to the design of adequate intervention and prevention programs, data on smoking behavior were collected from over 300 male and female 15 year olds from Poland and the United States, approximately half from each country. Several personality measures were obtained from each subject. Fifty of these students were already smoking and over 100 more had tried cigarettes. Results indicate that for both countries, smokers had a characteristic personality profile which included being anxious, angry, and impulsive/antisocial. In short they appear to be emotionally distressed and females were more extreme than males in this regard. Possible intervention and prevention strategies and future needed research are discussed.     

Immediate antecedents of cigarette smoking: an analysis of unrestricted smoking patterns

Theory suggests that cigarette smoking is under stimulus control and that affect is a key trigger for smoking. A previous study (S. Shiftman et al., 2002) showed little relationship between affect and smoking, but this relationship could have been suppressed by the impact of smoking restrictions. The study evaluated these associations in a 1988 sample that was subject to few smoking restrictions. Smokers (N = 28) not seeking treatment used palmtop computers to record context and affect prior to smoking (n = 2217 observations) and also at random times when not smoking (n = 2,380). Comparisons showed little relationship between smoking and affect. Smoking was associated with particular activities and locations. Urge to smoke was the strongest predictor of smoking. The results replicated the findings of S. Shiffman et al. (2002).     

The natural history of cigarette smoking: predicting young-adult smoking outcomes from adolescent smoking patterns

Assessed the magnitude of risk that adolescent cigarette smoking carries for adult smoking. Using a longitudinal, prospective design, results indicate that even infrequent experimentation in adolescence significantly raises the risk for adult smoking and that regular (at least monthly) adolescent smoking raises the risk for adult smoking by a factor of 16 compared to nonsmoking adolescents. Relative risk was also increased by an early onset of smoking and by a stable, uninterrupted course from experimentation to regular smoking. Relative risk did not significantly vary by age or sex. The continuity of smoking behavior between adolescence and adulthood supports the importance of primary prevention programs directed at adolescent populations.
