The goal of the present research was to resolve two problems with contemporary methods used to assess consumer food waste: the lack of established categories of food wasting behaviours and difficulties in assessing food waste. In Studies 1 A and 1 B, a five-factor questionnaire for measuring food wasting behaviours was developed. Study 2 and Exploratory analyses verified whether the questionnaire allows for predicting the amount of wasted meat, dairy and bakery and a range of socioeconomic characteristics.

Based on pre-registered studies, a new questionnaire for measuring the frequency of food wasting behaviours, the Food Wasting Behaviours Questionnaire (FWBQ), was developed.

The results provided evidence that behaviours associated with food wasting could be narrowed down to five distinctive basic categories: (1) discarding food because of its' unpalatability; (2) preventing food waste through buying only the necessities; (3) preventing food waste through planning; (4) preventing food waste through sharing and (5) preventing food waste through feeding animals. The FWBQ allowed for investigating the socio-economic factors that influence food wasting behaviour. Finally, the FWBQ allowed for predicting the amount of wasted meat, dairy and bakery products. Also, particular factors were associated with a range of socioeconomic characteristics.

The FWBQ has been shown to be an inexpensive and easy-to-use method for systematising distinct categories of food wasting behaviours and demonstrating their determinants. The study takes an empirical approach (rather than intuitive) to distinguish separate categories of food wasting.

People consider food wasting behavior to be immoral. However, it is not clear whether people who consider food wasting behavior immoral waste less food. Building on previous qualitative studies, we conducted a large-sample quantitative study. We examined whether people who consider food wasting behavior immoral display food wasting behaviors less frequently and whether they waste less food in general. Furthermore, we explored the reasons that make people consider food wasting behavior immoral and whether they affected food wasting.

Participants voluntarily (n = 562) completed a set of questionnaires that measured the frequency of their food wasting behavior, the amount of food wasted in the preceding week, and food wasting moral judgments, including scales, which explored the reasons for judging this behavior as immoral.

We found that people who regard food wasting behavior as immoral displayed food wasting behavior less frequently, but did not waste less food than people who did not consider food wasting behavior immoral. Furthermore, we found that there are two categories of reasons for moral disapproval of food wasting behavior: externally oriented (concern for the environment, social issues, and for future generations) and internally oriented (concern for ones’ financial situation, social approval, and going by traditional norms). However, only people whose moral judgments were motivated by externally oriented reasons wasted food less frequently.

Our findings provide evidence that moral judgments influence food wasting behavior and highlight the importance of the content of moral beliefs for predicting behaviors.

Food waste has strong ecological, economical and social implications. Focusing on waste perceptions and behavior according to food types, this paper aims to propose that vice or virtue food categories determine cognitive and behavioral reactions to food waste. The authors examine the psychological mechanism underlying the differential waste perceptions and behavior.

The authors conduct five studies, including a field study, to provide converging evidence that supports this theorization.

This study demonstrates that consumers feel that trashing vice food is more wasteful than trashing virtue food. They are less willing to waste vice food and more comfortable with wasting virtue food. Consequently, they waste more virtue than vice foods. The authors demonstrate that counterfactual thinking explains the food type effect on waste.

This paper provides a conceptual framework for understanding and explaining food waste perceptions and behavior across vice and virtue food categories. This paper identifies counterfactual thinking as underpinning the psychology of waste perceptions and behaviors. The findings extend the growing research on subconscious and unintentional food waste, the food consumption literature and the psychology of waste literature.

The differential waste perceptions and behavior provide several implications for waste interventions and consumer education. By expanding theories of consumer food waste, this paper provides material for educational campaigns aimed at reducing waste and improving healthful eating.

Consumers can benefit from understanding their tendency to avoid wasting vice foods but will waste virtue foods with little compunction. Waste aversion may be a reason people consume vice foods beyond satiation. Consumers may overconsume vice foods because they are so acutely averse to wasting them, with detrimental consequences for health and welfare.

To reduce consumer food waste, one must gain deeper insights into factors shaping consumer food waste perceptions and behavior. Food waste studies have been increasing but have overlooked the power of consumer perceptions in driving food waste consequences. To the best of the authors’ knowledge, no prior study has examined how food type affects waste perceptions and behavior. This research fills this gap.

Food waste behavior in the workplace or work-related gatherings has been less researched compared to that in household context. This study aims to bridge this gap through unfolding how and when quality of food waste prevention communication mitigates food waste behavior among frontline employees in the hospitality workplace.

Participants in this research comprised employees from four- and five-star hotels operating in Vietnam.

The results lent credence to the dual mediation channels of moral attitudes toward food wasting and meaningfulness of food waste reduction for the impact of quality of food waste prevention communication on employees’ food waste reduction intention and their reduced food waste behavior. The contingency role of employees’ green role identity was marginally confirmed for the nexus between employees’ food waste reduction intention and their food waste behavior.

This inquiry advances the understanding of mechanisms underlying work-related food waste behavior among hospitality employees.

This paper aims to demonstrate how the design of data visualisations can act as a tool to support social marketing messages in prompting behaviour change to reduce food waste using the Elaboration Likelihood Model (ELM) as a theoretical framework. It also responds to a lack of consumer-led insight to develop campaigns in reducing food waste.

The research uses data collected by the End Food Waste Cooperative Research Centre (EFW CRC) in Australia to determine which text-based campaign messages are most likely to prompt people toward reducing food waste. Behaviour change messages were first identified through workshops with 11 food waste experts, then explored through online focus group discussions with 18 participants from three food-wasting market segments. The messages were further tested via a quantitative survey among 1,000 decision makers in Australian households in their own homes, with the top three performing messages examined using summative content analysis.

The significant findings were that participants want to see 1) evidence of how adopting new behaviours would lead to financial savings and benefit the environment, and 2) concrete steps to reduce food waste. When examined through the ELM, the findings suggest that tools that encourage both cognitive and peripheral processing as a means of persuasion, like data visualisations, may be useful for changing food-wasting behaviours.

Applying principles from the field of communication design to the ELM has uncovered the potential for a cross-disciplinary approach to enhance theoretical frameworks for understanding consumer engagement with messages. This process in turn, may lead to the development of more effective behaviour change marketing strategies.

Six principles for using data visualisations in a social marketing campaign are proposed: personal relevance, ease of use, emotional storytelling, context, prioritising the message itself and long-term usage.

This study proposes that data visualisations could enhance the effectiveness of social marketing campaigns by leveraging consumer-derived insights and the persuasive capacity inherent in their theoretical underpinnings.

Behavioural change practice has focussed attention on understanding behaviour; failing to apply dynamic approaches that capture the underlying determinants of behavioural change. Following recommendations to direct analytical focus towards understanding both the causal factors of behaviour and behavioural change to enhance intervention practice, this paper aims to apply a hidden Markov model (HMM) approach to understand why people transition from one state to another (e.g. reporting changes from wasting food to not wasting food or vice versa).

Data were drawn from a 2017 food waste programme that aimed to reduce waste of fruit and vegetables by increasing self-efficacy through a two-week pilot, featuring recipes and in-store cooking demonstrations. A repeated measure longitudinal research design was used. In total, 314 households completed a phone survey prior to the two-week pilot and 244 completed the survey in the weeks following the intervention (77% retention in the evaluation study).

Two behavioural states were identified, namely, fruit and vegetable (FV) wasters and non-FV wasters. Age was identified as a causal factor for FV food wasting prior to the campaign (45-54 years were most likely to waste FV). Following the intervention, a total of 43.8% transitioned away from FV wasters to non-wasters, and attitudes and self-efficacy were indicated as potential causal factors of this change in FV waste behaviour.

Through this application, it is demonstrated how HMM can identify behavioural states, rates of behaviour change and importantly how HMM can identify both causal determinants of behaviour and behavioural change. Implications, limitations and future research directions are outlined.

Food wastage is a major contributor to pervasive world hunger. Cutting global food waste in half by 2030 is one of the United Nation's top priorities. Hence, this paper aims to provide useful insights on how individual behavior might be influenced to help reduce food wastage and hunger by identifying individual food waste determinants.

A total of 297 useable responses were obtained from a survey using a food diary method. A logit model was employed to estimate the relationship between leftovers and its determinants (preparedness to take own action, price conscious, food review, religiosity, health conscious, cost, marital status and gender).

Results show that preparedness to be responsible for one's actions, depending on food reviews and being waste conscious had a significant positive relationship with food waste reducing behavior, along with being male and being married.

The study suggests that there is scope for policy initiatives to reduce the individual utility from discarding food and increase the individual utility from food saving activities. Penalizing individual or household food wastage through a tax will directly raise the cost of wastage and reduce the net utility from discarding food. Reducing food waste could help reduce global hunger.

Rationally, no one will have any intention to waste when buying food. Instead, in the context of deciding whether or not to leave leftover food, an individual is posited to weigh the potential utility from saving food or throwing it away. Thus, this study examines food waste behavior by utilizing economic tools, which is rare in the food waste literature.

Social marketing and other types of targeted behaviour change interventions should appeal to an individual’s personal values in order to improve their effectiveness. However, there is currently little understanding of what these values are in relation to food waste. The purpose of this paper is to identify the values underpinning the specific behaviour of plate waste created in a residential foodservice setting.

In semi-structured interviews (n=50) laddering techniques were used to identify links from behaviours through individual’s rationalisation for that behaviour to their personal values. The aim of the questioning was to uncover underlying drivers that lead to plate waste as well as those barriers to reducing it.

The values identified as being most important are hedonism and self-direction. The specific aspects of these values for plate waste reduction interventions are not compromising on the individual’s enjoyment of the meal and meeting their health goals. Effective interventions include pre-ordering meals, reducing food options provided, reducing plate size, removing food tray and finally, information campaigns to raise awareness.

The study provides insights into the personal values that influence behaviours resulting in plate waste. The study is the first to determine the links between this behaviour, rationalisations for that behaviour and personal values.

Reducing food waste is one of the critical challenges of campus canteens. This study aims to test an extended theory of planned behaviour that incorporates moral norm, food taste and campus food-saving climate to understand the influence factors of food waste behaviour on campuses.

To evaluate the proposed model, an online survey was utilized to collect 513 valid questionnaires.

The findings suggest that (1) attitudes towards food waste, subjective norm and perceived behavioural control have a significant influence on intention to reduce food waste; (2) Moral norm and food taste are shown to have a favourable effect on the intention to reduce food waste; (3) Food waste behaviour is significantly determined by intention to reduce food waste; (4) Campus food-saving climate negatively moderates the relationship between intention to reduce food waste and food waste behaviour.

This study paves the way to enhance the understanding of the factors of food waste among college students. In addition, this study develops practical strategies to prevent large amounts of food from being wasted on campus.

This research examines the elements that influence consumer behavior regarding food waste reduction in buffet style restaurants. It specifically analyzes the factors that affect consumers' efforts to reduce food waste in these establishments by incorporating the theory of planned behavior (TPB), the norm activation model (NAM), and the social exchange theory (SET). Additionally, this study provides practical coping strategies for the restaurant industry.

Drawing upon an integrated framework, the study collected 547 valid responses through an online survey on Amazon’s Mechanical Turk (MTurk) for structural equation analysis. Participants who are 18 years or older and have prior experience dining in buffet style restaurants were eligible to participate in the study.

The findings underscore the profound impact of consumer awareness on their attitudes (ATT) toward minimizing food waste. Moreover, subjective norms (SN), perceived behavioral control (PBC), personal norms (PN) and establishment policies emerge as critical drivers of consumer behavior in buffet style dining settings. In light of these results, recommended strategies include enhancing consumer awareness initiatives and introducing house policies within restaurant operations.

This study employs an integrated framework that combines the NAM and TPB, taking into account the impact of house policies grounded in the SET. It provides a beneficial insight on reducing food waste in the buffet style foodservice operations from an interactive dynamic perspective between restaurants and consumers. Furthermore, this research offers valuable implications to the industry’s efforts to address food waste concerns and foster environmentally responsible behavior among consumers.
