Knowledge and Concerns About Smoking‐Related Health Risks
Perception of Anti-Smoking Campaigns and Pro-Tobacco Advertising Among People Who Smoke in Spain, 2016-2021
Smoking in Cars With Children
People Who Smoke Support Banning Smoking in Open Spaces in Spain
Social determinants of support for tobacco control policies to end the use of commercial cigarettes
Support for policies to reduce the use of commercial cigarettes was moderate-to-high among adults who smoke, although it varied significantly by country, gender and income. Tailored communication strategies could help increase support and promote policy adoption
What cigarette price would drive Vietnamese people who smoke to quit smoking? Findings from the 2019-2020 ITC Vietnam surveys
Given that the current cigarette prices are very low and affordable, substantial price increases are needed to motivate quitting. Adding specific taxes in addition to the existing ad valorem system could enhance the effectiveness of tobacco taxation
Use of nicotine pouches among adults who currently or formerly smoked cigarettes and/or vaped nicotine
We found a significant increase in NP ever-use and current use between 2022 and 2024 among adults with established nicotine product use, consistent with national sales trends. Further research is needed to determine whether adults are using NPs as a tool to quit smoking or sustain abstinence after quitting
People who smoke and formerly smoked do support a smoking ban in open spaces during and after the Covid-19 pandemic in Spain
Most people who currently or formerly smoked in Spain supported the outdoor smoking ban during and after the COVID-19 pandemic. This high acceptance suggests that the pandemic may have created an opportunity to strengthen tobacco control
The economic factors that determine smoking abstinence
Impacts of revised smoke-free regulations under the 2020 Japan Health Promotion Act on cigarette smoking and heated tobacco product use in indoor public places and homes
The implementation of the HPA was limited in its effectiveness. Comprehensive regulations with no exemptions are needed in Japan
Public support for tobacco endgame policies in South Korea
There is a strong public support for tobacco endgame policies in South Korea. Further research should prioritise the development of strategies to ensure the effective implementation of highly supported policies
Transformation of the tobacco product market in Japan, 2011–2023
While many factors may account for the decreased sale of cigarettes in Japan over the past 12 years, the increased sale of HTPs appears to be a factor
Evaluation of the effectiveness of the Indian government’s policies to strengthen health warning labels on smokeless tobacco products
There was no significant change in HWL effectiveness following the revision from a symbolic to a pictorial image, but enlarging pictorial images resulted in some improved cognitive and behavioural effects. Results suggested wear-out of HWL salience and that the effectiveness of warnings depends on both their design and time since implementation
Reasons for using e-cigarettes among adults who smoke
E-cigarette use for curiosity and pleasure predominated among adults who smoked. The reasons for dual use in adults have shifted from goal-oriented to non-goal-oriented
The association between excise taxes and smoking and vaping transitions–Findings from the 2016–2020 ITC United States surveys
Our findings suggest that increasing cigarette taxes may serve as an effective means of encouraging people who smoke to cut back on smoking or quit smoking. The impact of increasing EC taxes on smoking transitions is less certain at this time
Trend over time on knowledge of the health effects of cigarette smoking and smokeless tobacco use in Bangladesh
ITC Eurest-PLUS Spain
The ITC EUREST-PLUS Spain Survey is a longitudinal study of a representative sample of Spanish adult (≥18 years old) smokers. This protocol describes the methods of the 2021 follow-up survey. The ITC EUREST-PLUS Survey, a prospective cohort study of a representative sample of smokers in six European countries, was conducted in 2016 (baseline) and 2018 (waves 1 and 2). The 2021 ITC EUREST-PLUS Spain Survey is a continuation of the Spanish cohort w…
Reasons for Initiation and Regular Use of Heated Tobacco Products among Current and Former Smokers in South Korea
South Korea is the world’s second-largest heated tobacco product (HTP) market after Japan. HTP sales in South Korea have increased rapidly since May 2017, accounting for 10.6% of the total tobacco market in 2020. Despite this, little is known as to why HTP consumers who were current and former smokers started using HTPs and used them regularly. We analyzed cross-sectional data for 1815 adults (aged 19+) who participated in the 2020 International …
Associations of Cannabis Use, High-Risk Alcohol Use, and Depressive Symptomology with Motivation and Attempts to Quit Cigarette Smoking Among Adults
The online version contains supplementary material available at 10.1007/s11469-023-01214-8
Differences in Smoking Cessation Behaviors and Vaping Status among Adult Daily Smokers with and Without Depression, Anxiety, and Alcohol Use
This study examined differences in quit attempts, 1-month quit success, and vaping status at follow-up among a cohort of 3709 daily smokers with and without depression, anxiety, and regular alcohol use who participated in both the 2018 and 2020 International Tobacco Control Four Country Smoking and Vaping (ITC 4CV) Surveys. At baseline, a survey with validated screening tools was used to classify respondents as having no, or one or more of the fo…
The association between risk perceptions, anxiety, and self-reported changes in tobacco and nicotine product use due to Covid-19 in May-June 2020 in Israel
While many respondents believed that nicotine product use (particularly CCs and e-cigarettes) was associated with increased risk of COVID-19 disease severity, the majority of users did not change their tobacco/nicotine use. The confusion about the relationship between tobacco use and COVID-19 calls for clear evidence-based messaging from governments. The association between home smoking and increased COVID-19-related stress suggests the need for …
Smokers’ strategies to reduce tobacco spending
The majority reported using strategies to reduce spending or that price played a role in their decision to quit. Reducing consumption was the most reported strategy. Low-income smokers were more likely to reportedly reduce consumption, buy cheaper products, or quit. Price policies have the potential to reduce socioeconomic inequalities in smoking. To discourage price-minimising behaviours, such as switching to cheaper products, reducing price dif…
Support for nicotine reduction in cigarettes
More than half of respondents in all four countries-including those who smoked daily-supported a hypothetical VLNC standard to render cigarettes less addictive. It is important to examine if support is sustained after policies are implemented
Insights into the accuracy of social scientists' forecasts of societal change
Do post‐quitting experiences predict smoking relapse among former smokers in Australia and the United Kingdom? Findings from the International Tobacco Control Surveys
Establishing a causal chain
The authors propose that experiments that utilize mediational analyses as suggested by R. M. Baron and D. A. Kenny (1986) are overused and sometimes improperly held up as necessary for a good social psychological paper. The authors argue that when it is easy to manipulate and measure a proposed psychological process that a series of experiments that demonstrates the proposed causal chain is superior. They further argue that when it is easy to man…
Reductions in HIV risk-associated sexual behaviors among black male adolescents
BACKGROUND. The number of reported cases of acquired immune deficiency syndrome (AIDS) is increasing disproportionately among Blacks in the United States. The relatively high incidence of sexually transmitted diseases among Black adolescents suggest the need for AIDS prevention programs to reduce their risk of sexually transmitted human immunodeficiency virus (HIV) infection. METHODS. Black male adolescents (n = 157) were randomly assigned to rec…
Motivated recruitment of autobiographical memories
We hypothesized that people motivated to believe that they possess a given trait search for autobiographical memories that reflect that trait, so as to justify their desired self-view. We led subjects to believe that either extraversion or introversion was desirable, and obtained convergent evidence from open-ended memory-listing tasks as well as from reaction-time tasks measuring the speed with which memories could be generated that this manipul…
Alcohol myopia and condom use
We tested 2 competing theories about the effects of alcohol on intentions to engage in risky behavior. Disinhibition predicts that intoxicated people will exhibit risky behavior regardless of environmental cues, whereas alcohol myopia (C. M. Steele & R. A. Josephs, 1990) predicts that intoxicated people will be more or less likely to exhibit risky behavior, depending on the cues provided. In 4 studies, we found an interaction between intoxication…
Reducing HIV risk‐associated sexual behavior among african american adolescents
This randomized controlled trial tested the effects of a theory‐based culture‐sensitive HIV risk‐reduction intervention among 496 inner‐city African American adolescents (mean age = 13 years) and examined the generality of its effects as a function of the facilitator's race and gender and the gender composition of the intervention group. Adolescents who received the HIV risk‐reduction intervention expressed more favorable behavioral beliefs about…
Inadmissible evidence and juror verdicts
288 mock jurors watched videotapes of a realistic simulated trial and rendered verdicts as individuals before deliberation and as groups after deliberation. In a 3 × 2 design, the trial evidence and judge's instructions were varied. The trial contained inadmissible evidence supporting conviction, in

Path analysis of warning label effects on negative emotions and quit attempts
Negative emotions elicited by warnings encourage behavior change, promoting attention to warnings and behavioral responses that positively predict quit attempts
Graphic Canadian Cigarette Warning Labels and Adverse Outcomes
Objectives. We assessed the impact of graphic Canadian cigarette warning labels. Methods. We used a longitudinal telephone survey of 616 adult smokers. Results. Approximately one fifth of participants reported smoking less as a result of the labels; only 1% reported smoking more. Although participants reported negative emotional responses to the warnings including fear (44%) and disgust (58%), smokers who reported greater negative emotion were mo…
Effectiveness of an HIV/STD Risk-Reduction Intervention for Adolescents When Implemented by Community-Based Organizations
Objectives. We evaluated the effectiveness of an HIV/STD risk-reduction intervention when implemented by community-based organizations (CBOs). Methods. In a cluster-randomized controlled trial, 86 CBOs that served African American adolescents aged 13 to 18 years were randomized to implement either an HIV/STD risk-reduction intervention whose efficacy has been demonstrated or a health-promotion control intervention. CBOs agreed to implement 6 inte…

Conhecimento e uso de cigarros eletrônicos e percepção de risco no Brasil
Devido às incertezas sobre o impacto dos cigarros eletrônicos na saúde, o Brasil adotou, em 2009, regulamentação que proibiu venda, importação e propaganda desses produtos até que fabricantes possam demonstrar que são seguros e/ou efetivos na cessação de fumar. O objetivo do estudo foi analisar entre fumantes brasileiros: (1) conhecimento sobre existência de cigarros eletrônicos, uso na vida, e uso recente; (2) percepção de risco sobre cigarros e…
Adult smokers' perception of the role of religion and religious leadership on smoking and association with quitting
Mesurer les effets de la méthode de collecte des données
Les enquêtes recourant à un mode mixte de collecte sont de plus en plus nombreuses, et il devient nécessaire de tester les écarts entre les réponses obtenues par téléphone et par internet. Cet article analyse les effets des différents modes de collecte en utilisant la vague 1 de l'enquête International Tobacco Control (ITC) des Pays-Bas réalisée par internet (CAWI) et par téléphone (CATI). Pour de nombreuses questions, les échantillons présentent…

Prepaid Monetary Incentives-Predictors of Taking the Money and Completing the Survey
Prepaid monetary incentives are used to address declining response rates in random-digit dial surveys. There is concern among researchers that some respondents will accept the prepayment but not complete the survey. There is little research to understand check cashing and survey completing behaviors among respondents who receive prepayment. Data from the International Tobacco Control Four-Country Study-a longitudinal survey of smokers in Canada, …

Abstinence and Safer Sex HIV Risk-Reduction Interventions for African American Adolescents
CONTEXT: African American adolescents are at high risk of contracting sexually transmitted infection with human immunodeficiency virus (HIV), but which behavioral interventions to reduce risk are most effective and who should conduct them is not known. OBJECTIVE: To evaluate the effects of abstinence and safer-sex HIV risk-reduction interventions on young inner-city African American adolescents' HIV sexual risk behaviors when implemented by adult…

Tobacco Denormalization and Industry Beliefs Among Smokers from Four Countries
Exposure to Tobacco Marketing and Support for Tobacco Control Policies
Effects of the 2003 advertising/promotion ban in the United Kingdom on awareness of tobacco marketing
The UK policy to ban tobacco advertising and promotion has significantly reduced exposure to pro-tobacco marketing influences. These findings support the effectiveness of comprehensive bans on advertising and promotion, as included in the Framework Convention on Tobacco Control
Socioeconomic variations in nicotine dependence, self-efficacy, and intention to quit across four countries
To the extent that lower SES smokers are more addicted, they are likely to need more intensive support if they are to be successful in their attempts to quit. Given their lower incomes, this places a special responsibility on government to provide or subsidise such services. This should include access to the widest possible range of effective pharmacotherapies complemented with evidence based counselling and support
Support for and reported compliance with smoke-free restaurants and bars by smokers in four countries
Among current cigarette smokers, support for smoking bans was associated with living in a place where the law prohibits smoking. Smokers adjust and both accept and comply with smoke-free laws. Associates of support and compliance are remarkably similar across countries given the notably different levels of smoke-free policies
Cigarette purchase patterns in four countries and the relationship with cessation
Data from this study indicate that there are lower levels of making a quit attempt among purchasers of low/untaxed cigarettes compared to purchasers of full-priced cigarettes. The availability of low/untaxed cigarettes may mitigate the influence of increases in cigarette prices
Effectiveness of cigarette warning labels in informing smokers about the risks of smoking
Smokers are not fully informed about the risks of smoking. Warnings that are graphic, larger, and more comprehensive in content are more effective in communicating the health risks of smoking
Individual-level predictors of cessation behaviours among participants in the International Tobacco Control (ITC) Four Country Survey
Intention to quit and other cognitive variables were associated with quit attempts, but not cessation. Behavioural variables related to task difficulty, including measures of dependence, predicted both making attempts and their success. Predictors of making quit attempts and cessation were similar for each of the four countries, but there were some differences in predictors of success
Socioeconomic and country variations in knowledge of health risks of tobacco smoking and toxic constituents of smoke
Lower socioeconomic status was associated with lower awareness of the harms of smoking and misunderstanding around nicotine. There is a need to improve knowledge of the dangers of smoking among the disadvantaged segments of the population
Determinants and consequences of smoke-free homes
Smoke-free public places seem to stimulate adoption of smoke-free homes, a strategy associated with both increased frequency of quit attempts, and of the success of those attempts
Reductions in tobacco smoke pollution and increases in support for smoke-free public places following the implementation of comprehensive smoke-free workplace legislation in the Republic of Ireland
The Ireland smoke-free law stands as a positive example of how a population-level policy intervention can achieve its public health goals while achieving a high level of acceptance among smokers. These findings support initiatives in many countries toward implementing smoke-free legislation, particularly those who have ratified the Framework Convention on Tobacco Control, which calls for legislation to reduce tobacco smoke pollution
