Physical inactivity and sedentary behaviours are leading risk factors for preventable health problems worldwide. Therefore, several smartphone-based interventions have tried to enhance physical activity (PA) through goal reminders based on relatively stable characteristics. However, time-varying factors, such as cognitive fatigue, may act as barrie...

Empirical studies have persistently reported negative attitudes of meat eaters toward vegetarians and vegans (veg*ns), but scant attention has been paid to veg*ns' attitudes toward meat eaters. We aimed to investigate the attitudes of meat eaters and veg*ns from both perspectives. In addition, we explored the attitudes of occasional meat eaters. We...

The use of reflective interfaces has been proposed as a useful strategy to reduce cyber harassment amongst adolescents on social networking sites (SNS). By using machine-learning techniques, harassing online messages can be detected before a user submits it online, whereafter a message prompts the user to reconsider the post. This study builds furt...
Article
There is an abundance of messages on food and health communicated nowadays by diverse stakeholders, including nutrition and health experts, food industries, celebrity chefs, and food influencers, among others. If each of these stakeholders has different interests and uses other communication strategies, confusion and polarization about food and hea...

Boredom is a prevalent and relevant, yet understudied, negative emotion in the field of media psychology. This paper proposes novel theoretical foundations to study boredom as an emotion and its related regulation strategies in the context of mobile media. Due to their pervasive nature, mobile media allow for boredom regulation via passive and (int...
Article
Despite the substantial amount of literature concerning adolescent bystanders of online hate and cyberbullying, relatively little attention has been devoted to studying the same issue in adults. Similarly, the determinants of the effectiveness of different messages to support the victims or counter hate have also been understudied. The existing pie...
Article
Combining the transactional model of stress and coping and expressive writing theory, this research studied whether writing on one’s personal experiences with the COVID-19 pandemic may improve young people’s emotional reactions to the situation. A standard expressive writing instruction was compared to a positive writing instruction (writing about...

Next, we show a step-by-step plan of how to employ this co-design in the context of designing an efficient and effective interface to support victims cope positivel...
Article
This study explores what emerging adults value in food media, i.e. food-focused content and personae in media. Emerging adults (18–25) are an important target group for food media as they transition toward nutritional independence and consume media substantially. Seven semi-structured focus groups were conducted with thirty-seven Belgian participan...

The measures to fight the spread of the COVID-19 pandemic have been concentrated on inviting people to stay at home. This has reduced opportunities to exercise while also shedding some light on the importance of physical health. Based on an online survey, this paper investigated physical activity behaviours of a Belgians sample (n = 427) during the...
Article

This study investigates whether healthy food can be made more appealing by looking at the pleasure induced by the social context in which food is eaten (eating alone, eating together, or sharing food), assuming that pleasure affects food appeal. Whereas unhealthy food is often considered a source of pleasure, healthy food is not. The pleasure induc...

Sharing, reading and responding to personal narratives on peer-to-peer support websites may provide adolescents with informational and emotional support to feel more confident in coping with stressful events. However, their use may also pose a threat to adolescents’ coping self-efficacy. Principles of expressive writing, social sharing of emotions,...
Chapter
Personalization is about conveying the right message at the right time to the right person. Since the beginning of trade, offline sellers already establish personalized experiences by learning things about their loyal customers (i.e., name, preferences), and by implementing this knowledge in interactions with them (i.e., call them by name, offer pe...

Whereas, past research has shown that using environmental arguments to reduce meat intake are unsuccessful in awareness campaigns, popular documentaries might have the potential to successfully change the public awareness of the environmental implications of meat consumption today. This preliminary study aimed to provide first empirical evidence of...
Article
Full-text available
The literature has advocated the use of a clear and unambiguous label to inform adolescents of advertisements on social media. In this study, we introduce a norm-based label and determine its effects. In a series of three studies, we test a label that triggers the bandwagon heuristic (i.e., “your friends know this is sponsored”) and compare its eff...

In this study, 245 Facebook users between 18 and 35 years of age (Mage = 25.97, SD = 4.92) were asked to order tickets for the movies through Cinebot, a Facebook chatbot specifically built for the study. Afterwards, they were asked to...
Article
As readers often do not recognize the commercial nature of native advertising on news websites, clear disclosures are required to prevent deception. The present study therefore tests whether and how providing disclosures with more detailed information about both the authorship of native ads and the importance of advertising revenue for news media’s...
Article
Mobile news consumption is rising quickly, just as the appearance of native advertisements on mobile news platforms, yet little is known about readers’ mobile native advertising recognition and perceptions.

Article
Facebook users do not visit the social networking site to see advertising. They are either just surfing the platform or searching for information.

Ad blocking – the use of browser extensions such as Adblock (Plus) or Ublock – is becoming mainstream, particularly amongst young web users. This automated form of advertising avoidance has attracted significant attention due to the loss of advertising revenues. Insights in this type of ad avoidance behavior are indispensable. By applying the theor...

This paper starts from the premise that crisis is a perception and that one of the best ways to conquer a crisis is not to allow it to develop in the first place. By detecting or perceiving a crisis before other stakeholders do, an organisation can prevent or mitigate a crisis. Few studies have considered the question of whether organisations put t...
