Hope for the best or prepare for the worst? Calm perseverance, not vigilant monitoring, contributes to adolescent life satisfaction
OBJECTIVE: Which kind of self-regulatory strategies contribute to life satisfaction in adolescence? MATERIALS AND METHODS: In the present research, we tested two competing hypotheses arguing that either a strategy of vigilant monitoring of opportunities for working towards goal achievement or a calm perseverance strategy steadily working towards goals in a slower pace would promote life satisfaction in a large and diverse sample of adolescents. W…
Community nudges
Nudges are behavioral interventions to subtly steer citizen choices by making desirable options easier or more attractive. More than 15 years of research and practice have revealed that such gentle encouragements are effective policy instruments in directing personal decisions without violating the principles of good governance. However, with a focus on individual behavior, there has been less attention to nudges as a policy device for promoting …
Understanding the dynamics and interplay of public support and adherence to five key mitigation behaviors over the course of the evolving Covid-19 pandemic
Behavioral measures played a critical role in mitigating the COVID-19 pandemic, and their success hinged on continued public support and adherence. This study provides novel evidence on changes in support and adherence to behavioral mitigation measures and appraises the role of pandemic fatigue to provide robust guidance for effective governance of future public health and safety crises. Data were collected from a population cohort study in the N…
When and how behavior change can accelerate system change (and vice versa)
System change and individual behavior change are often conceptualized as contrasting, mutually exclusive strategies for climate change mitigation, with system change usually considered more powerful, direct or urgent. We argue that this alleged duality is misguided and that system change and behavior change are fundamentally co-dependent: system change is often effective to the extent that it promotes individual behavior change and, vice versa, i…
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…
Collective Decision Making and Support for Covid ‐19 Measures at Campus
Although the importance of a collective action approach for pandemic management has been acknowledged during the recent COVID‐19 pandemic, actual attempts at involving people in designing a package of mitigation measures were absent. Our research examines the potential of active participation of the student community in collective pandemic decision making in the university setting. We address two questions. First, would a student population be wi…
Co‐Creation Through Collaborative Governance
This study assesses the process and outcomes of co‐creation for developing healthier and more sustainable food environments (i.e., food environments that stimulate healthy and sustainable food choices) in three Dutch neighbourhoods, engaging diverse stakeholders—local residents, entrepreneurs and municipal officials—while adhering to collaborative governance principles. The co‐creation process comprised five phases: (1) exploration, where the res…
Rethinking behaviour change interventions in policymaking
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…
How does nudging the Covid-19 vaccine play out in people who are in doubt about vaccination
In spite of the growing availability of COVID-19 vaccines, a substantial number of people is reluctant or uncertain about getting the vaccine. Nudges may improve vaccine uptake but it is unclear how this plays out with the experience of autonomous choice, decision competence, decision satisfaction, and being pressured to make a choice. In an online experiment among a representative sample (N = 884), we examined whether a social norm nudge or a de…
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…
Prompting vegetable purchases in the supermarket by an affordance nudge
The supermarket is a promising location for stimulating healthier food choices by nudging interventions. However, nudging healthy food choices in the supermarket has shown weak effects to date. The present research introduces a new nudge based on the concept of affordances - i.e., an animated character - that invites interaction with healthy food products and examines its effectiveness and appreciation in a supermarket context. We present finding…
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…
Nudgeability
Nudges are behavioral interventions to subtly steer citizens’ choices toward “desirable” options. An important topic of debate concerns the legitimacy of nudging as a policy instrument, and there is a focus on issues relating to nudge transparency, the role of preexisting preferences people may have, and the premise that nudges primarily affect people when they are in “irrational” modes of thinking. Empirical insights into how these factors affec…
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…
Does default organ donation registration compromise autonomous choice? Public responses to a new donor registration system
Defaults have been shown to increase the number of organ donor registrations but it is unclear whether they violate personal autonomy of the people being registered. The implementation of a new Donor Act in the Netherlands, providing people with the opportunity for active registration before being defaulted, allowed for examining to what extent default registration affects personal autonomy and associated concepts. In an online survey among a rep…
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
Misperceived eating norms
The current food environment communicates the social norm that it is normal to consume large amounts of unhealthy and unsustainable foods. However, it is unknown whether people endorse this norm because they agree with it, or whether they endorse it because they overestimate the degree to which other people agree with this norm - a phenomenon that is labeled as 'pluralistic ignorance'. We examined the possible presence of pluralistic ignorance by…
Keep your distance for me”
The outbreak of COVID-19 has turned out to be a major challenge to societies all over the globe. Curbing the pandemic requires rapid and extensive behavioural change to limit social interaction, including physical distancing. In this study, we tested the notion that inducing empathy for people vulnerable to the virus may result in actual distancing behaviour beyond the mere motivation to do so. In a large field experiment with a sequential case-c…
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…
Eating behavior and food purchases during the Covid-19 lockdown
Snacks and The City
While many people declare an intention to eat and snack more healthily, a large body of research has found that these intentions often do not translate into actual behavior. This failure to fulfil intentions is regularly attributed to the obesogenic environment, on which basis it is assumed that changing the food environment may lead to more healthy snacking behavior. To test this premise in real life practice, the present research project invest…
Simple nudges that are not so easy
In this paper, we critically review three assumptions that govern the debate on the legitimacy of nudging interventions as a policy instrument: (1) nudges may violate autonomous decision-making; (2) nudges lend themselves to easy implementation in public policy; and (3) nudges are a simple and effective mean for steering individual choice in the right direction. Our analysis reveals that none of these assumptions are supported by recent studies e…

Eating by example. Effects of environmental cues on dietary decisions
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…

Confabulating reasons for behaving bad
Numerous studies have been conducted to demonstrate that behaviours are frequently activated unconsciously. The present studies investigate the downstream psychological consequences of such unconscious behaviour activation, building on work on the explanatory vacuum and post‐priming misattribution. 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…

Structure and Determinants of Illness Representations in Chronic Disease
Although the clinical relevance of illness representations has been demonstrated in several studies, research on the structure and determinants of illness representations is rare. This article examines the illness representations of chronically ill patients, using a structured interview technique and taking chronic fatigue syndrome (CFS) and Addison's disease (AD) as examples. Considerable differences were found between the group of CFS patients …

Making plans for healthy diet
The main objective of the present study was to examine the role of motivation and action orientation in forming spontaneous (i.e., without specific instruction or manipulation) implementation intentions for a healthy diet goal. We hypothesized that (1) the adoption of a diet goal would be determined by (either intrinsic or extrinsic) motivation only whereas, (2) forming implementation intentions would be determined by intrinsic motivation and (ei…
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…
