Together towards sustainable dining – Cocreating behavioral change interventions with restaurants
Behavioral change interventions in restaurants towards sustainable food choices are a promising avenue towards attaining climate goals. In this research, we investigated how these interventions can successfully be implemented in a restaurant context to promote sustainable food choices. In a multiple-year co-creation project with 32 restaurants and consultant chefs, we provided knowledge on sustainable meal preparation and on using behavioral inte…
How do people understand the spread of Covid-19 infections? Mapping mental models of factors contributing to the pandemic
OBJECTIVE: To describe the mental models people hold about the COVID-19 pandemic, with a focus on how they understand the factors that drive the spread of COVID-19 and what kind of beliefs are associated with these models. DESIGN: In a series of three studies (total N = 461), we asked participants to identify factors that are relevant for COVID-19 proliferation (Study 1a), rate the importance of factors (Study 1 b), and create a mental model of h…
Nudging towards sustainable dining
Food choice behavior plays a large role in achieving sustainability goals. Meat in particular has a negative environmental impact as compared with plant-based food - and is more frequently chosen in restaurant contexts. To increase plant-based meal choices in restaurants, we tested three nudges for menus that are likely to be implemented by restaurant owners: a hedonic label (e.g., artisanal vegetable burger), a chef's recommendation (specifying …
Understanding public support for Covid-19 pandemic mitigation measures over time
Background: COVID-19 mitigation measures intend to protect public health, but their adverse psychological, social, and economic effects weaken public support. Less favorable trade-offs may especially weaken support for more restrictive measures. Support for mitigation measures may also differ between population subgroups who experience different benefits and costs, and decrease over time, a phenomenon termed "pandemic fatigue." Methods: We examin…
Personal values, motives, and healthy and sustainable food choices
People are increasingly eating out in restaurants, where meals tend to be higher in calories, less nutritious, and contain more meat. In this paper, we argue that differences in the motivational processes underlying people's food choices could help to explain why food choices made in restaurants are typically unhealthier and less sustainable than at home. Using online survey data from 301 Dutch participants, we compared the influence of stable pe…
Mental models of the protein shift
The protein transition is one of today's major societal challenges to mitigate climate change. To support lasting consumer engagement, it has been suggested to look into consumers' understanding of the protein transition to identify barriers that go beyond the practical issues of changing one's diet. The current study explored consumers' mental models of how the transition unfolds to examine which factors consumers perceive as important drivers o…
Make it a habit
OBJECTIVE: Hand washing has been at the core of recommendations and guidelines that aim to curb infectious diseases in general, and COVID-19 in particular. As hand washing comes down to an individual's behaviour, we aimed to study how individual psychological variables influence hand washing over time during the COVID-19 pandemic. DESIGN: Over the course of 20 weeks, participants answered questions about their hand washing behaviour, goal importa…
Snacking for a reason
Whereas low socio-economic position was associated with higher stress levels, this did not translate into increased snacking. Contrarily, those with higher socio-economic position could be more prone to using 'reasons to snack', which may result in justification of unhealthy snacking behaviour
Under pressure
Previous research has shown that nudging can effectively support people's healthy food choices. Yet, to date knowledge about the psychological premises of nudging is limited, highlighting the need for closer scrutiny to determine how and when nudging is most effective. In the current study, we assessed whether the presumed effect of nudging on healthy food choice is enhanced under time pressure, a condition probing alleged system 1 reasoning. Foo…
The (bitter) sweet taste of nudge effectiveness
Seemingly insignificant daily practices, such as sugar usage in tea, can have a great accumulated impact on societal issues, such as obesity. That is why these behaviours are often the target of nudge interventions. However, when these behaviours are performed frequently they may turn into habits that are difficult to change. The aim of the current study was to investigate whether a portion size nudge has the potential to work in accordance with …

Nudging healthy food choices
BACKGROUND: Recognizing the mindless nature of many food decisions, it has been suggested that attempts to increase healthy eating should not focus on convincing people what is 'right' but rather aim to adjust the environment such that people are automatically directed toward healthy choices. This study investigated a nudge aiming to promote healthy food choices in train station snack shops. METHODS: The nudge involved a repositioning of food pro…

Effects of Trait Self‐Control on Response Conflict About Healthy and Unhealthy Food
Self‐control leads to positive life outcomes, but it is poorly understood. While previous research has focused on self‐control failure, self‐control success remains unexplored. The current studies aim to shed more light on the mechanisms of self‐control by focusing on the resolution of response conflict as a key component in self‐control success. Trait self‐control was measured, and participants reported on the magnitude of response conflict they…

Effortless Self‐Control
Self‐control is of invaluable importance for well‐being. While previous research has focused on self‐control failure, we introduce a new perspective on self‐control, including the notion of effortless self‐control, and a focus on self‐control success rather than failure. We propose that effortless strategies of dealing with response conflict (i.e., competing behavioral tendencies) are what distinguishes successful self‐controllers from less succe…
Hungry for an intervention? Adolescents’ ratings of acceptability of eating-related intervention strategies
Adolescents preferred intervention strategies that promote healthy eating over strategies that discourage unhealthy eating. Level of intrusiveness affected acceptability ratings for the latter type of strategies only. Various individual and behavioral characteristics were associated with acceptability. These findings provide practical guidance for the selection of acceptable intervention strategies to improve adolescents' eating behavior

Bedtime procrastination
BACKGROUND: Procrastination is a prevalent and problematic phenomenon that has mostly been studied in the domain of academic behavior. The current study shows that procrastination may also lead to harmful outcomes in the area of health behavior, introducing bedtime procrastination as an important factor related to getting insufficient sleep and consequently affecting individual well-being. Bedtime procrastination is defined as failing to go to be…
Don't tell me what I should do, but what others do
Objectives While healthy eating patterns are of high importance in adolescence, most adolescents portray quite unhealthy eating behaviour. One reason for this may be that social norms among peers tend to be unsupportive of healthy eating. The current study investigates whether communicating health‐promoting descriptive and injunctive norms influences adolescents' intended and actual fruit consumption. Design The study employed an experimental pro…

When planning is not enough
In two experiments a self‐regulatory strategy combining mental contrasting with the formation of implementation intentions (MCII) was tested for its effectiveness in diminishing unhealthy snacking habits. Study 1 ( N = 51) showed that participants in the MCII condition consumed fewer unhealthy snacks than participants in a control condition who thought about and listed healthy options for snacks. In Study 2 ( N = 59) MCII was more effective than …
License to sin
Hedonic overconsumption is often considered to be caused by impulsive factors. The current paper investigates whether self‐licensing, relying on reasons to justify subsequent gratification, can also be included as a significant contributor to hedonic consumption. Two studies were conducted to investigate whether self‐licensing can account for an increase in hedonic consumption while ruling out impulsive factors such as resource depletion, negativ…

Numerous studies have been conducted to demonstrate that behaviours are frequently activated unconsciously.

It was hypothesized that unconsciously activated behaviours trigger a negative affective response if the behaviour violates a personal standard and th…
Less is more
Implementation intentions have been shown to effectively change counter‐intentional habits. Research has, however, almost solely been concerned with the effectiveness of a single plan. In the present research, we investigated the behavioral and cognitive implications of making multiple implementation intentions targeting unhealthy snacking habits and its underlying processes, linking multiple habitual snacking cues to healthy alternatives. Study …

Tricky treats
This series of studies examined the effect of temptation strength on self-regulation processes in the context of eating behavior. Based on the critical level model, it was hypothesized that weak, rather than strong, temptations yield the most unfavorable conditions for effective self-regulation, because the negative consequences of the former are underestimated. In line with the assumptions of this model, Studies 1 and 2 showed that weak temptati…
Adaptive Tasks, Coping and Quality of Life of Chronically Ill Patients
This article is a report of a larger study on the relationship between adaptive tasks, coping and quality of life, taking Parkinson's disease and chronic fatigue syndrome (CFS) as examples. The concept of adaptive tasks or disease-related stressors testing the adaptive capacities of chronically ill patients ( N=134) was explored by applying the method of concept mapping. Results show that patients both with Parkinson's disease and with CFS genera…

Feeding Your Feelings
The process by which emotions affect eating behavior emerges as one of the central unresolved questions in the field of emotional eating. The present studies address the hypothesis that the regulation strategies people use to deal with these emotions are responsible for increased eating. Negative emotions were induced and intake of comfort food and non—comfort food was measured by means of taste tests. Emotion induction was preceded by measuring …

Taking Stock of Self-Control
Given assertions of the theoretical, empirical, and practical importance of self-control, this meta-analytic study sought to review evidence concerning the relationship between dispositional self-control and behavior. The authors provide a brief overview over prominent theories of self-control, identifying implicit assumptions surrounding the effects of self-control that warrant empirical testing. They report the results of a meta-analysis of 102…
