Many adolescents and young adults consume a lot of alcohol, which is related to serious negative consequences for both youth and society. A recent development is that young people nowadays place a lot of posts about this alcohol use on Social Networking Sites (SNS), such as Facebook and Instagram. Alarmingly, most of these messages show […]

Published on October 4th, 2016 – Obesity is a major problem in Western countries, causing a wide variety of chronic diseases, such as heart disease, type 2 diabetes, and certain types of cancer. It is therefore vital to employ cost-effective, large-scale interventions to promote healthier lifestyles. In the United States, restaurants are required to use […]

This PhD project focuses on gaining a better understanding of aspects that determine the effectiveness of interpersonal communication about alcohol and binge drinking. The overarching goal is to explore how interpersonal communication can be used to improve anti-alcohol and binge drinking interventions targeted at late adolescents (17-19 years old). We examine aspects such as: conversational […]

Low-educated adolescents with learning difficulties drink and smoke more than other adolescents. How can this target group be effectively educated about alcohol and tobacco? In this project, this is studied among 12-15 year old adolescents who follow schools for special education or adolescents at pre-vocational schools who receive special attention. Seven experiments are performed that […]

Opinions differ on whether it is wise or foolish to have recovered addicts inform adolescents about the risk of use of alcohol, tobacco or drugs (ATOD). Some think that this will deter adolescents from using ATOD; in contrast, others think that this might stimulate experimental use. On the one hand, by informing adolescents in a […]

The Netherlands and more than 170 other countries have ratified the Framework Convention on Tobacco Control (FCTC). The FCTC includes legally binding international rules on topics such as tobacco marketing, pricing policies, health warning labels, education, and smoke-free legislation. The International Tobacco Control Policy Evaluation Project  (ITC project) is specifically designed to evaluate the impact […]

Extant research shows that interpersonal communication between people has more influence than professional health communication. This project aims at increasing insight into how people communicate about health-related behaviors and how this influences health behavior. In addition, interpersonal communication can both strengthen and weaken the effects of professional health communication (e.g., campaigns). More knowledge on the […]

An unhealthy lifestyle is the main cause of chronic diseases, resulting in reduced quality of life and preventable healthcare costs. As budgets for healthcare become increasingly limited, low-cost lifestyle improvement strategies are needed. A strategy proven to be (cost-)effective is online individually tailored health communication. To date, tailoring entailed adjusting what information was provided, but […]

Tobacco smoking is the most prevalent cause of preventable non communicable diseases, like cancer. Many Dutch smokers therefore attempt to quit smoking, but only 4-10% of these quit attempts are successful. Evidence-based smoking cessation support tools, such as pharmacotherapy, counseling and online interventions, have been shown to double the chance of successful quitting. However, Dutch […]

To aid smokers to quit, effective smoking cessation interventions such as the provision of smoking cessation advice by general practice staff, are essential. Within the general practice, preventive tasks are often delegated to practice nurses. Practice nurses increase the quality of care and relieve general practitioners from their excessive workload. Yet, adherence to smoking cessation […]

Worldwide, the smoking of tobacco is the most preventable cause of illness and premature death. As smokers intrinsically motivated to quit smoking are more successful in quitting than extrinsically motivated smokers, knowledge of the determinants of intrinsic and extrinsic motivation to quit is essential to increase cessation rates. Therefore, the goal of this project was […]

Tobacco smoking is the most prevalent cause of preventable non communicable diseases, like cancer. Online computer-tailored interventions have already shown to be (cost-)effective in improving smoking cessation, over and above more static health communication, but effect sizes remain small. The large majority of the tailored interventions developed and tested so far only tailor the content […]

Medication adherence is not optimal in patients with rheumatoid arthritis and varies between 22% (underuse) and to 107% (overuse). Medication non-adherence is a relevant clinical problem as it can result in more disease activity, radiological damage, a lower quality of life, and increased health care costs. Thus, effective interventions to improve medication adherence are warranted. […]

Within this project, we investigate the long-term impact of asthma patients’ self-management behaviors on their health outcomes, as well as several modifiable factors that may influence how patients self-manage their asthma. We have conducted a cohort study in France and the United Kingdom that follows up patients (adults and children) for up to 2 years […]

In 2016, all EU member states will start using pictorial warning labels on cigarette packages. This means that cigarette packages will not only contain verbal warnings such as: “smoking kills”, but that this text will be accompanied by a picture of a dead body, for instance. There is quite some debate among scientists on whether […]

People are continuously exposed to risk information from public health organizations, such as information about cancer risk and obesity risk. Research has demonstrated that these communication strategies can be effective, but there are also instances in which exposure to risk communication has adverse effects, such as message rejection, denial of risk, and drop-out from prevention […]

People make judgements of personal risk for health problems based on information they obtain from news media, for instance cancer incidence reports in news broadcasts or obesity-prevention strategies from newspapers. There is, however, substantial evidence showing that incidence reports in the media are not in line with evidence from epidemiological research, or that news media […]

Understanding the extent to which what communication strategies are effective to change fruit and vegetable intake is relevant for public health, as sufficient intake of fruit and vegetables has substantial beneficial effects for health. This meta-analysis will summarize and meta-analyse the literature from 1980 to 2014 on this issue. Inclusion criteria are (a) randomized allocation […]

Promoting post-motivational strategies, such as monitoring and action planning, have become immensely popular in health communication. The basic tenet of these strategies centres around the postulate that motivation alone is not sufficient for people to act healthy. Although there is substantial evidence that action planning promotes healthy behaviour, there is also evidence suggesting this is […]

Nonexperimental research has shown that instrumental attitudes (what do I think about the behaviour), affective attitudes (what do I feel about the behaviour), and self-regulation variables (when and how should I do the behaviour) are important predictors of health behaviour (such as physical inactivity) and non-health related (such as curbside recycling) behaviours. The aim of […]
