Introduction
Research within the context of (public) health promotion, mainly focusing on the prevention and intervention of overweight and obesity. I have a special interest in the influence of the built and social environment on individuals' food intake. In addition, I am interested in the possibilities of persuasive technology in behaviour change.

Alcohol portrayal in movies and commercials is generally positive and might stimulate young people to drink. We tested experimentally whether portrayal of alcohol images in movies and commercials on television promotes actual drinking. In a naturalistic setting (a bar lab), young adult male pairs watched a movie clip for 1 h with two commercial bre...

Numerous studies have shown that people adjust their intake directly to that of their eating companions; they eat more when others eat more, and less when others inhibit intake. A potential explanation for this modeling effect is that both eating companions' food intake becomes synchronized through processes of behavioral mimicry. No study, however...

Purpose of Review There is abundant evidence that food marketing influences children’s and adults’ food preferences and consumption. As such, exposure to unhealthy food marketing is a widely acknowledged risk factor contributing to the development of overweight and obesity. Less is known about the effects of healthy food promotion on people’s dieta...

BACKGROUND The family environment plays an important role in the development of children’s energy-balance related behaviors (EBRBs). As a result, parents’ energy-balance parenting practices (EBRPPs) are eminent targets of preventive childhood obesity programs. Families with a lower socioeconomic position (SEP) may benefit from participating in such...

Public health nutrition is concerned with the promotion and maintenance of good health through nutrition and the prevention of nutrition-related illness in humans. Nutrition communication plays an important role in the dissemination of credible and practical dietary advice and promoting healthful dietary behaviors. The purpose of this chapter is to...
Article
Full-text available
Background: Eating rate is a basic determinant of appetite regulation: people who eat more slowly feel sated earlier and eat less. A high eating rate contributes to overeating and potentially to weight gain. Previous studies showed that an augmented fork that delivers real-time feedback on eating rate is a potentially effective intervention to dec...

Purpose The purpose of this study has three primary aims. The first is to examine the amount of time children spend per week on viewing vlogs. Second, the authors explored children’s awareness and understanding of the brand or product placement in vlogs. Finally, the authors explored children’s self-perceived susceptibility to the potential persua...

Full-text available
Introduction: It has been proposed that the use of cue-reminders may increase the effectiveness of interventions that aim to prevent health-risk behaviors (i.e., having unsafe sex, unhealthy dietary intake, lack of physical activity, and substance use). The aim of this systematic review was to explore whether there is evidence supporting this propo...
Article
Objective: Serious games are a promising venue to increase children's nutritional knowledge in an entertaining format. The aim of this study was to test the short-term effectiveness of the Alien Health Game, a videogame designed to teach elementary school children about nutrition and healthy food choices. Materials and methods: To examine the ef...
Article
Although parents often report positive intentions to promote and create a healthy food environment for their children (e.g., setting limits to snacks offered), they also experience difficulties in translating these intentions into actual behaviors. In this position paper, we argue that automatic processes explain an important part of the gap betwee...
Article
Full-text available
Background To improve the effectiveness of school-based programs that aim to promote adolescents’ healthy food choices, it is essential to understand the views and behaviors of the target group. This study aimed to get a better understanding of adolescents’ food and health perceptions and their willingness to be involved in a specific school-based...
Article
Eating rate is a basic determinant of appetite regulation, as people who eat more slowly feel sated earlier and eat less. Without assistance, eating rate is difficult to modify due to its automatic nature. In the current study, participants used an augmented fork that aimed to decelerate their rate of eating. A total of 114 participants were random...
Article
Full-text available
Although there is evidence that people tend to match their intake to that of others, less is known about the motives underlying this effect. The current study, therefore, examined the relationship between self-esteem, a specific factor that has been related to the likelihood of social matching. Further, we examined the effects of food matching on i...
Article
There is evidence that perceived peer eating norms can influence dietary behaviour. This cross-sectional study examined whether certain personality traits increase the likelihood that personal eating habits are similar to perceived peer eating habits. We assessed frequency of consumption of sugar sweetened soda (SSS) and sweet pastries (SP), as wel...
Article
BACKGROUND The purpose of this study was to examine the association between adolescents' body mass index (BMI) z-scores and their subsequent level of schooling, extending previous longitudinal research by using objectively measured weight and height data. METHODSA longitudinal study with 3 study waves (1-year intervals) involving 1248 Dutch adolesc...
Article
Full-text available
This study investigated whether social modeling of palatable food intake might partially be explained by the direct imitation of a peer reaching for snack food and further, assessed the role of the children's own weight status on their likelihood of imitation during the social interaction. Real-time observations during a 10-min play situation in wh...

To prevent harmful drinking, it is essential to understand factors that promote alcohol use at an early age. The aim of the present study was to examine the role of parental alcohol use in children’s selection of alcoholic beverages in a virtual reality (VR) environment and their intentions to drink in the future. Participants were 7–13-year-old ch...
Article
The self-control strength model suggests that exertion of self-control leads to poorer subsequent self-control performance. Failure of self-control has been suggested as an important underlying mechanism of excessive drinking. This study tested the effects of self-control failure on ad-lib drinking, and the potential moderating role of glucose and...

One's decisions about eating are at times, largely based on the observations of other people's eating behavior. Previous studies have shown that modeling of eating is a robust effect. The current research examined the impact of a video remote confederate on young women's food intake. Experiment 1 examined the effect of an eating or non-eating video...
Article
Full-text available
Numerous studies have shown that people adjust their intake directly to that of their eating companions. A potential explanation for this modelling effect is that the eating behaviour of others operates as an external eating cue that stimulates food intake. The present study explored whether this cue-reactive mechanism can account for modelling eff...
Article
Full-text available
Portion size and the intake of others have been found to influence people's food intake. No study, however, has tested the potential influences of both types of situational norms on intake during the same eating occasion. We experimentally tested the effects of manipulating portion size and the intake of others on young women's meal intake during a...

Article
This study examined whether young men adjusted their snack-food intake to that of a same-sex eating companion. Additionally, hunger was assessed as a possible moderating variable. A total of 59 young men (M age=21.73) participated. An interaction between participants' hunger and confederate's intake on the total amount of snack food (in grams) cons...
Article
This study investigates the effects of the quality of social interaction on modeling of food intake among young women. A two (confederate's food intake: high versus low) by two (confederate's sociability: sociable versus unsociable) between-participant factorial design was employed. A total of 100 young women (18-27 years) participated. Findings in...
