Item does not contain fulltext, The effects of vulnerability, severity, costs, effort, and effectiveness on prevention behavior, derived from protection motivation theory and the health belief model, have been extensively tested in the literature and have all been shown to predict rather well. In this study we test the effects of these determinants in a new context: the domestic risk prevention domain. The specific behaviors under study are related to the risks of burglary, fire, and water damage. In addition to previous studies, our multilevel research design allows us to evaluate which differences in the performance of domestic prevention behavior can be attributed to differences between persons and which to differences between behaviors within persons. Our results show that all determinants are relevant predictors for domestic risk prevention behavior. Disentangling the within-person and between-person effects shows that prevention behavior depends more on the relative evaluation of the prevention behavior determinants for a given person (e.g., a person perceives a smoke alarm to be more effective than antiburglar strips), than on the differences between persons regarding the general perception of these determinants (e.g., some persons find prevention behaviors in general more effective than other persons). To increase the performance of domestic risk prevention behaviors, we advise that interventions should focus on increasing a person's perception of risks and prevention behaviors relative to other risks and prevention behaviors rather than focusing on changing people's general perceptions of all risks and behaviors or focusing on specific target groups.

Background: We aimed to expand the number of currently known pathogenic PNKP mutations, to study the phenotypic spectrum, including radiological characteristics and genotype-phenotype correlations, and to assess whether immunodeficiency and increased cancer risk are part of the DNA repair disorder caused by mutations in the PNKP gene. Methods: We evaluated nine patients with PNKP mutations. A neurological history and examination was obtained. All patients had undergone neuroimaging and genetic testing as part of the prior diagnostic process. Laboratory measurements included potential biomarkers, and, in the context of a DNA repair disorder, we performed a detailed immunologic evaluation, including B cell repertoire analysis. Results: We identified three new mutations in the PNKP gene and confirm the phenotypic spectrum of PNKP-associated disease, ranging from microcephaly, seizures, and developmental delay to ataxia with oculomotor apraxia type 4. Irrespective of the phenotype, alpha-fetoprotein is a biochemical marker and increases with age and progression of the disease. On neuroimaging, (progressive) cerebellar atrophy was a universal feature. No clinical signs of immunodeficiency were present, and immunologic assessment was unremarkable. One patient developed cancer, but this was attributed to a concurrent von HippelLindau mutation. Conclusions: Immunodeficiency and cancer predisposition do not appear to be part of PNKP-associated disease, contrasting many other DNA repair disorders. Furthermore, our study illustrates that the previously described syndromes microcephaly, seizures, and developmental delay, and ataxia with oculomotor apraxia type 4, represent the extremes of an overlapping spectrum of disease. Cerebellar atrophy and elevated serum alpha-fetoprotein levels are early diagnostic findings across the entire phenotypical spectrum.

Contains fulltext : 237852.pdf (Publisher’s version ) (Open Access), A potentially effective way to influence people's fire prevention behavior is letting them experience a fire in an immersive virtual environment (IVE). We analyze the effects of experiencing a fire in an IVE (versus an information sheet) on psychological determinants of behavior - knowledge, vulnerability, severity, self-efficacy, and locus of control - based mainly on arguments from Protection Motivation Theory and the Health Belief Model. Crucial in our setup is that we also relate these determinants to actual prevention behavior. Results show that IVE has the hypothesized effects on vulnerability, severity, and self-efficacy, and an unexpected negative effect on knowledge. Only knowledge and vulnerability showed subsequent indirect effects on actual prevention behavior. There remains a direct positive effect of IVE on prevention behavior that cannot be explained by any of the determinants. Our results contradict the implicit assumption that an induced change in these psychological determinants by IVE, necessarily implies a change in behavior. A recommendation for research on the effects of IVE's is, whenever possible, to study the actual target behavior as well.

In the relation between patient and clinician, communication is a central aspect. In this short paper, we conceptualize patient-generated data (PGD) as a means of communication. We present a case study in which we explore the experiences of clinicians and patients with PGD. We identify and discuss some real-world trade-offs in using PGD both effectively and meaningfully in clinical practice. Our key finding is that data collection and sharing is about a lot more than the data itself, and that a process of collective meaning making is required to focus on clinically relevant information, and to ground the communication in a sufficiently shared understanding of the subjective experiences associated with objective data points.

Objective To examine (1) the impact of pictorial cigarette warning labels on changes in self-reported warning label responses: warning salience, cognitive responses, forgoing cigarettes and avoiding warnings, and (2) whether these changes differed by smokers' educational level.Methods Longitudinal data of smokers from two survey waves of the International Tobacco Control (ITC) Europe Surveys were used. In France and the UK, pictorial warning labels were implemented on the back of cigarette packages between the two survey waves. In Germany and the Netherlands, the text warning labels did not change.Findings Warning salience decreased between the surveys in France (OR=0.81, p=0.046) and showed a non-significant increase in the UK (OR=1.30, p=0.058), cognitive responses increased in the UK (OR=1.34, pConclusions The warning labels implemented in France in 2010 and in the UK in 2008 with pictures on one side of the cigarette package did not succeed in increasing warning salience, but did increase avoidance. The labels did not increase educational inequalities among continuing smokers.

Contains fulltext : 159159.pdf (publisher's version ) (Open Access), Background: Hardcore smokers are smokers who have smoked for many years and who do not intend to quit smoking. The "hardening hypothesis" states that light smokers are more likely to quit smoking than heavy smokers (such as hardcore smokers). Therefore, the prevalence of hardcore smoking among smokers would increase over time. If this is true, the smoking population would become harder to reach with tobacco control measures. In this study we tested the hardening hypothesis. Methods: We calculated the prevalence of hardcore smoking in the Netherlands from 2001 to 2012. Smokers were 'hardcore' if they a) smoked every day, b) smoked on average 15 cigarettes per day or more, c) had not attempted to quit in the past 12 months, and d) had no intention to quit within 6 months. We used logistic regression models to test whether the prevalence changed over time. We also investigated whether trends differed between educational levels. Results: Among smokers, the prevalence of hardcore smoking decreased from 40.8 % in 2001 to 32.2 % in 2012. In the general population, it decreased from 12.2 to 8.2 %. Hardcore smokers were significantly lower educated than non-hardcore smokers. Among the general population, the prevalence of hardcore smoking decreased more among higher educated people than among lower educated people. Conclusions: We found no support for the hardening hypothesis in the Netherlands between 2001 and 2012. Instead, the decrease of hardcore smoking among smokers suggests a 'softening' of the smoking population.

People like variety and often prefer to choose from large item sets. However, large sets can cause a phenomenon called “choice overload”: they are more difficult to choose from, and as a result decision makers are less satisfied with their choices. It has been argued that choice overload occurs because large sets contain more similar items. To overcome this effect, the present paper proposes that increasing the diversity of item sets might make them more attractive and satisfactory, without making them much more difficult to choose from. To this purpose, by using structural equation model methodology, we study diversification based on the latent features of a matrix factorization recommender model. Study 1 diversifies a set of recommended items while controlling for the overall quality of the set, and tests it in two online user experiments with a movie recommender system. Study 1a tests the effectiveness of the latent feature diversification, and shows that diversification increases the perceived diversity and attractiveness of the item set, while at the same time reducing the perceived difficulty of choosing from the set. Study 1b subsequently shows that diversification can increase users’ satisfaction with the chosen option, especially when they are choosing from small, diverse item sets. Study 2 extends these results by testing our diversification algorithm against traditional Top-N recommendations, and finds that diverse, small item sets are just as satisfying and less effortful to choose from than Top-N recommendations. Our results suggest that, at least for the movie domain, diverse small sets may be the best thing one could offer a user of a recommender system.

Objectives To examine if exclusive Roll-Your-Own (RYO) tobacco use relative to factory-made (FM) cigarette use has been rising over time, to determine the extent to which economic motives and perceptions that RYO cigarettes are less harmful act as primary motivations for use, and to examine the association of income and education with the level of RYO tobacco use among smokers in four European countries. Methods Data were obtained from the International Tobacco Control (ITC) Europe Surveys, and a cohort sample of 7070 smokers from the Netherlands, Germany, France and UK were interviewed between June 2006 and December 2012. Generalised estimating equations (GEE) were used to assess trends in RYO use, and whether RYO consumption varied by socioeconomic variables. Results Exclusive RYO use over the study period has increased significantly in the UK from 26.4% in 2007 to 32.7% in 2010 (p

Tobacco control policies seemed to have failed to reduce socioeconomic inequalities in smoking in the past. It has been argued that a comprehensive mix of policies is needed. Our aim was to assess whether tobacco control policy development in the Netherlands between 1988 and 2011 was associated with educational inequalities in smoking cessation and cigarette consumption. Data were derived from the cross-sectional Dutch Continuous Survey of Smoking Habits, with a study sample of 259,140 respondents from 1988 through 2011. Outcomes were the quit ratio and mean number of cigarettes smoked per day. The determinant was the Tobacco Control Scale (TCS). We used multilevel logistic regression modeling, with years, quarters, and individuals as levels, and controlled for sex, age, and time. A significant association between the TCS and smoking cessation was found in 2001-2011, but not in 1988-2000. Associations for low- and high-education groups were similar (OR = 1.23; 95% CI = 1.12-1.34 and OR = 1.17; 95% CI = 1.03-1.32 respectively). The TCS was not significantly associated with the number of cigarettes smoked per day for either the low- or high-education groups (B = -0.09; 95% CI = -0.46-0.27 and B = -0.59; 95% CI = -1.24-0.06 respectively). Strong tobacco control policies introduced in the Netherlands after 2000 were positively associated with national trends in smoking cessation, whereas weaker policies introduced gradually before 2000 were not. However, these measures do not seem to have either widened or narrowed educational inequalities in smoking cessation rates-both groups benefitted about equally.

Background In 2011, the Netherlands implemented a national policy that ensured that health insurance companies reimbursed behavioural counselling for smoking cessation or the combination of behavioural counselling with pharmacological therapy. Objective To examine the real-world impact of a national reimbursement policy and accompanying media attention on use of cessation treatment and on smoking cessation. Methods We used a four-wave longitudinal survey among 2763 adult smokers that started in September 2010 and was repeated at approximately 3 month intervals until June 2011. Two survey waves were conducted before the implementation of the policy and two survey waves after. Findings There were significant increases in quit attempts (among moderate-to-heavy smokers) and in quit success (among all smokers) following the implementation of the reimbursement policy and the media attention. Use of behavioural counselling did not increase, while use of pharmacological therapy without behavioural counselling (unreimbursed treatment) increased among moderate-to-heavy smokers. Attention to media about the reimbursement was significantly associated with more quit attempts and more quit success. Awareness of the policy was significantly associated with more use of reimbursed treatment among all smokers, while attention to the media coverage was only significantly associated with more use of reimbursed treatment among moderate-to-heavy smokers. Awareness/attention variables were not significantly associated with use of unreimbursed treatment. Conclusions It seems that a national reimbursement policy for smoking cessation treatment that is accompanied by media attention can increase cessation. Our findings suggest that this increase can (partly) be ascribed to the media attention that accompanied the policy implementation.

This study examined educational differences in associations of noticing anti-tobacco information with smoking-related attitudes and quit intentions among adult smokers. Longitudinal data (N = 7571) from two waves of six countries of the International Tobacco Control (ITC) Europe Surveys were included. Generalized estimating equation analyses and multiple linear and logistic regression analyses were conducted. Higher educated smokers noticed anti-tobacco information slightly more often than lower educated smokers (F(2) = 25.78, P <0.001). Noticing anti-tobacco information was associated with more negative smoking-related attitudes (beta = 0.05, P <0.001) and more quit intentions (OR = 1.08, P <0.001). Among smokers without a quit intention at baseline, a positive association was found for noticing anti-tobacco information at baseline with follow-up quit intention (OR = 1.14, P = 0.003). No other longitudinal associations were found. No educational differences were found in the association of noticing anti-tobacco information with smoking-related attitudes but associations with quit intentions were found only among low (OR = 1.12, P = 0.001) and high educated respondents (OR = 1.11, P <0.001) and not among moderate educated respondents (OR = 1.02, P = 0.43). Noticing anti-tobacco information may positively influence quit intentions and possibly smoking-related attitudes. Lower educated smokers were as likely to be influenced by anti-tobacco information as higher educated smokers but noticed anti-tobacco information less often; increasing reach of anti-tobacco information may increase impact in this group.

Introduction: The aim of the current study is to investigate trends and socioeconomic differences in policy triggers for thinking about quitting in six European countries.Methods: Data were derived from all available survey waves of the International Tobacco Control (ITC) Europe Surveys (2003-2013). France conducted three survey waves (n = 1420-1735), Germany three waves (n = 515-1515), The Netherlands seven waves (n = 1420-1668), Ireland three waves (n = 582-1071), Scotland two waves (n = 461-507), and the rest of the United Kingdom conducted seven survey waves (n = 861-1737). Smokers were asked whether four different policies (cigarette price, smoking restrictions in public places, free or lower cost medication, and warning labels on cigarette packs) influenced them to think about quitting. Generalized Estimating Equation (GEE) models were estimated for each country.Results: Cigarette price was mentioned most often in all countries and across all waves as trigger for thinking about quitting. Mentioning cigarette price and warning labels increased after the implementation of price increases and warning labels in some countries, while mentioning smoking restrictions decreased after their implementation in four countries. All studied policy triggers were mentioned more often by smokers with low and/or moderate education and income than smokers with high education and income. The education and income differences did not change significantly over time for most policies and in most countries.Conclusions: Tobacco control policies work as a trigger to increase thoughts about quitting, particularly in smokers with low education and low income and therefore have the potential to reduce health inequalities in smoking.

Introduction: Several states implemented comprehensive smoke-free laws in workplaces (14 states), restaurants (17 states), and bars (13 states) between 2002 and 2007. We tested the hypothesis that public support for smoke-free laws increases at a higher rate in states that implemented smoke-free laws between 2002 and 2007 (group A) than in states that implemented smoke-free laws after that time or not at all (group B). The period before the implementation (1992-2001) was also considered.Methods: Data was used from the Current Population Survey (CPS) Tobacco Use Supplements (TUS), which is representative for the U.S. adult population. Respondents were asked whether they thought smoking should not be allowed in indoor work areas, restaurants, and bars and cocktail lounges. Differences in trends were analyzed with binomial mixed effects models.Results: Population support for smoke-free restaurants and bars was higher among group A than among group B before 2002. After 2002, support for smoke-free restaurants and bars increased at a higher rate among group A than among group B. Population support for smoke-free workplaces did not differ between group A and B, and the increase in support for smoke-free workplaces also did not differ between these groups.Conclusions: The positive association between the implementation of smoke-free restaurant and bar laws and the rate of increase in support for these laws partly supported the hypothesis. The implementation of the laws may have caused support to increase, but also states that have higher support may have been more likely to implement smoke-free laws.

Background: Not much is known about how people in the Netherlands respond to electronic cigarettes (e-cigarettes); how many know about them, which people try them, keep using them and why, and what are changes over time regarding awareness and use?Methods: We used samples of smokers aged 15 years and older from 2008 (n = 1820), 2010 (n = 1702), 2013 (n = 1530), and 2014(n = 1550) as part of the International Tobacco Control (ITC) Netherlands Survey. Reasons for use and characteristics of smokers were examined using the sample from 2014. Logistic regression analyses were conducted to evaluate the associations between smoking-related variables with ever trying e-cigarettes and current e-cigarette use.Results: In 2014,91.4% of Dutch smokers reported being aware of e-cigarettes (97.1% in 2008, 89.2% in 2010, and 85.5% in 2013),40.0% reported having ever tried them (13.4% in 2008,14.5% in 2010, and 19.6% in 2013), and 15.9% were currently using them (4.0% in 2008,1% in 2010, and 3.9% in 2013). The main reason given for using e-cigarettes was to reduce the number of regular cigarettes smoked per day (79%). Ever trying e-cigarettes among those aware of e-cigarettes was associated with being young, smoking more regular cigarettes per day, having made a quit attempt in the last year, having used smoking cessation pharmacotherapy in the last year, and reporting high awareness of the price of regular cigarettes. Smokers who kept using e-cigarettes had a higher educational background, had higher harm awareness for the health of others, and were less likely to have a total smoking ban at home.Conclusion: E-cigarettes are increasingly used by Dutch smokers. Commonly endorsed motivations for current e-cigarette use were to reduce tobacco smoking and because e-cigarettes are considered to be less harmful than tobacco cigarettes. (C) 2014 Elsevier B.V.

Background: This study examined possible income differences in the impact of a national reimbursement policy for smoking cessation treatment and accompanying media attention in the Netherlands in 2011.Methods: We used three waves of the International Tobacco Control (ITC) Netherlands Survey, a nationally representative longitudinal sample of smokers aged 15 years and older (n = 1912). The main analyses tested trends and income differences in outcome measures (smokers' quit attempt rates, use of behavioral counseling, use of cessation medications, and quit success) and awareness variables (awareness of reimbursement possibilities, the media campaign, medications advertisements and other media attention) with generalized estimating equations analyses.Results: In the first half of 2011, there was a significant increase in quit attempts (odds ratio (OR)= 2.02, pConclusions: The Dutch reimbursement policy with accompanying media attention was followed by an increase in quit attempts and quit success, but use of cessation treatment remained stable. The impact of the policy and media attention did not seem to have decreased or increased socioeconomic inequalities in quit attempts, use of cessation treatment, or quit success.

Smoking is in the Netherlands more prevalent among lower and moderate educated than among higher educated people. The entertainment-education television show 'I bet I can do it!' was specifically designed to stimulate smoking cessation among low and moderate educated smokers.The effect of the television show was evaluated with longitudinal data of the International Tobacco Control Policy Evaluation Project. Dutch smokers (n = 1,743) aged 15 years and older filled in a survey before and after the seven episodes of 'I bet I can do it!' in 2008.Low educated (OR = 1,55, p = 0,048) and moderate educated respondents (OR = 1,99, p <0,001) had seen the television show significantly more often than high educated respondents. The show was not significantly associated with self efficacy, quit intention, and quit success, but it was significantly associated with more quit attempts among moderate educated respondents (OR = 2,36, p <0,001).The reach of 'I bet I can do it!' and the effect on quit attempts was larger among moderate educated smokers. The entertainment-education strategy for smoking cessation television programs should be further refined. This can possible lead to a program that has positive effects on the quit intention, self efficacy, quit attempts and the quit success of low and moderate educated smokers.
