Assessing System Justification in Czech Population Using the System Justification Scale
Article
Full-text available
  • Sep 2023
System justification (SJ) is an important construct in social psychology that has received considerable attention over the past three decades. At the empirical level, system justification is examined by means of a specially developed System Justification Scale (SJS), which is designed to explain how individuals accept justice, whether they consider a given social order to be fair, how they evaluate the conditions in the country in which they live, how they accept social change, or to what extent they express compliance with established rules. System justification involves not only those who benefit from the existing social order, but also those who are disadvantaged. In their case, system justification mitigates negative perceptions of objective inequalities and asymmetries. Empirical evidence suggests that system justification may also be associated with higher perceived quality of life. The present study translated and validated the SJS, providing complex and detailed information on the psychometric properties of the scale. In addition, the scale's internal consistency, unidimensionality, and construct validity were examined. The conclusions presented are based on the results of exploratory factor analysis, internal consistency assessment, analysis of variance, correlation analysis, and confirmatory factor analysis. Results were obtained from face-to-face survey data collected from a sample of 1419 individuals representing the Czech population aged 18-79 years. Since the SJS showed high internal consistency, adequately discriminated levels of system justification, and had robust psychometric properties, it could be recommended for further use.

Translating and Validating the Frugality Scale among the Czech Population
Article
Full-text available
  • Aug 2023
Frugality is an important psychological trait that is currently of interest as a research construct in a range of fields, from consumer behavior to financial literacy and financial well-being. Increasingly, the concept of frugality is also being linked to environmental responsibility and behavior, as the core of frugality is the reduction or minimization of resources used and consumed, an emphasis on the long-term use of purchased products, and an overall conservation of resources. For many years, researchers have used the Frugality Scale (FS), the specific research tool introduced to measure frugality in a standardized and valid way. The aim of the study was to examine the psychometric properties of FS translated into the Czech language, to evaluate the uni-dimensionality of the construct, and to analyze associations with relevant variables documenting respondents' attitudes and behavior. For this purpose, the research based on face-to-face interviews among respondents representing the 15-74 years old population of Czechia was conducted. The obtained results showed that the previously developed FS achieved very good results in the Czech environment, where the obtained scores supported the hypothesized uni-dimensional structure of the scale. The CFA results show that the tested model fits well with empirical data. Convergent and construct validity is also shown to be high. Therefore, the Czech version of the Frugality Scale can be considered a reliable and valid instrument that is recommended for further use. By utilizing the FS, researchers and practitioners gain access to a robust tool for quantifying frugality and comprehending its pertinent aspects across diverse contexts.

Validation of the Health Consciousness Scale among the Czech Population
Article
Full-text available
  • Jun 2023
The COVID-19 pandemic has demonstrated the importance of maintaining good health. It became has become apparent that health consciousness is a crucial factor in promoting healthy lifestyles, disease prevention, and the overall well-being of individuals. A higher level of health consciousness is associated with healthy habits, better adherence to medical recommendations, and a higher quality of life. Therefore, health consciousness is a critical construct in health care that reflects the degree to which individuals care about their health. This study, which is based on a representative sample of the adult population (n = 1372), aims to validate the Health Consciousness Scale (HCS) to assess its reliability and validity, and evaluate the factor structure of the translated version of the scale in the Czech language. The validation of the HCS in the Czech context is a significant step forward and provides useful information for healthcare professionals, policymakers, and researchers. The findings of this study contribute to the understanding of health consciousness in the Czech population and provide unique information for the development and evaluation of health interventions aimed at promoting healthy behaviors and attitudes.

No time to waste: assessing the performance of food waste prevention actions
Article
Full-text available
  • Oct 2020
  • RESOUR CONSERV RECY
As a result of the growing awareness of the need to prevent food waste, several initiatives have been launched in the last few years to reduce food waste generated across the food supply chain. However, the evaluation of food waste prevention interventions is still at an early stage of development and appropriate methods to assess their effectiveness are missing, hampering the identification of best practices amongst existing initiatives and the prioritisation of those that are most promising. To address such needs and provide a common approach to consistently assess the performance of food waste prevention initiatives, the European Commission Joint Research Centre has developed an evaluation framework for food waste prevention actions. The framework supports the EU Platform on Food Losses and Food Waste, which has been established to identify best practices and share knowledge on food waste prevention initiatives. Additionally, a food waste prevention calculator, based on life cycle thinking, has been developed to support such an evaluation by a consistent assessment of the environmental and economic benefits of such initiatives, and the identification of potential trade-offs at early design stages. The main goal of this paper is to present the evaluation framework and the calculator developed, critically discussing how future initiatives should be designed, monitored and reported, to ensure sufficient and relevant data is made available to enable their proper assessment. Crucially, this would enable practitioners and decision makers to evaluate the success of existing initiatives and give priority to the implementation of the best performing ones.

Food waste matters - A systematic review of household food waste practices and their policy implications
Article
Full-text available
  • Feb 2018
  • J CLEAN PROD
In recent years, food waste has received growing interest from local, national and European policymakers, international organisations, NGOs as well as academics from various disciplinary fields. Increasing concerns about food security and environmental impacts, such as resource depletion and greenhouse gas emissions attributed to food waste, have intensified attention to the topic. While food waste occurs in all stages of the food supply chain, private households have been identified as key actors in food waste generation. However, the evidence on why food waste occurs remains scattered. This paper maps the still small but expanding academic territory of consumer food waste by systematically reviewing empirical studies on food waste practices as well as distilling factors that foster and impede the generation of food waste on the household level. Moreover, we briefly discuss the contributions of different social ontologies, more particularly psychology-related approaches and social practice theory. The analysis reveals food waste as a complex and multi-faceted issue that cannot be attributed to single variables; this also calls for a stronger integration of different disciplinary perspectives. Mapping the determinants of waste generation deepens the understanding of household practices and helps design food waste prevention strategies. Finally, we link the identified factors with a set of policy, business, and retailer options.

Drivers of food waste and their implications for sustainable policy development
Article
Full-text available
  • Dec 2015
  • RESOUR CONSERV RECY
There has been growing interest in establishing food waste prevention and recovery programs throughout the world. The drive to target food waste stems from increasing concerns about resource conservation, food security, food waste's environmental and economic costs, and a general trend in the waste management industry to transition to more sustainable practices. Here the drivers of residential, institutional, and commercial food waste generation in developed countries, particularly in the U.S., are explored. The impacts of food system modernization on food waste generation are examined, including impacts related to food system industrialization, urbanization, globalization, and economic growth. Socio-demographic, cultural, political, and economic drivers of food waste are described with emphasis on how food waste perspectives may vary globally. Specific behaviors and attitudes which result from many of these waste drivers are then discussed. The examination of the range of food wastage drivers are used to provide insight into the best policy approaches to sustainably manage food waste. Food waste prevention policies are placed in context of the waste generating behaviors and attitudes that they address. A review of important background information on food waste is also provided, including definitions of key terms, food waste history, quantities of food waste generated, and the importance of food waste prevention for sustainability, as this information is all critical for effective policy development.

Estimating Food Waste as Household Production Inefficiency
Article
  • Jan 2020
Measuring food waste at the individual household level has been nearly impossible because comprehensive, current data on uneaten food do not exist. By using food acquisition data, this article employs a new approach to estimating household‐level food waste via a stochastic production frontier model in which food waste is identified as input inefficiency. For households in our data, the average household wastes 31.9% of the food it buys, and this figure, using survey weights, translates to annual U.S. consumer‐level food waste valued at $240 billion. In addition, by accommodating heterogeneous wasting behavior, we find that healthier diets and higher income lead to more household food waste, whereas lower household food security, food‐assistance program participation, and larger household sizes are associated with less food waste.

The effect of date labels on willingness to consume dairy products: Implications for food waste reduction
Article
  • Aug 2018
  • WASTE MANAGE
In the context of national and cross-national efforts to reduce the quantity of food wasted by consumers, there is growing interest in the role of date labelling. Recent proposals by policy makers and the food industry to address dairy product waste have included streamlining date-label application and encouraging the use of best-before dates where possible. In order for these measures to have a positive impact on food waste, consumers must not only know the difference between date types, but also be prepared to act on this information and consume products after the best-before date. Through a survey of 548 Scottish consumers we investigated the relationship between product type, date type, reduced labels and willingness to consume (WTC) dairy products in relation to the both the best-before date and the use-by date. We also examined the factors associated with different levels of WTC products in relation to the best-before date including knowledge, risk perceptions and trust. Our results suggest that on their own, the effect on food waste of applying best-before dates to dairy is likely to be small. In order for such changes to be effective, consumer communication that goes beyond improving expiry-date knowledge and addresses the multifaceted nature of related risk perceptions and conceptions of date-label trust will be required.

Relevance of selected measures in transition to a circular economy: The case of the Czech Republic
Article
  • Mar 2018
To accelerate the transition to a circular economy European member states have applied a broad range of policy instruments. Based on recycling rates and public participation in recycling efforts the Czech Republic would also appear to be on the way to a circular economy. However, the environmental effect of policy instruments (e.g. promotion and education campaigns) will soon be exhausted, as recycling rates are no longer rising significantly. Convinced recyclers are already carrying out effective recycling; however, how to motivate chronic non-recyclers to increase their public participation in recycling efforts is questionable. This paper examines the impact of social norms and the social environment in an attempt to explain recycling behaviour. Furthermore, awareness of waste separation options and programs is viewed as an important variable that deter-mines how non-recyclers perform with regard to recycling.

Consumers’ food cycle and household waste. When behaviors matter
Article
  • Mar 2018
  • J CLEAN PROD
Recent studies have shown that consumers encounter various conflicting motivations that influence the prevention of household food waste. Food choices are rooted in deep-seated judgments, such as emotions, habits, and values, thus raising the cognitive dissonance between motivation and behavior (intention-behavior gap). The complexity of this subject increases when considering that food waste is driven by repetitive, multiple, and hidden individual choices and influenced by a composite set of situational factors. This study argues the presence of a critical distance between food choices and waste generation in homes and this factual interval (behavior-outcome gap) further affects consumer's decision-making when comparing available options. Employing data from a three-year survey of a national representative panel of Italian consumers, this study develops a system of regression models using path analysis methodology. The objective is to measure the relationships between the different phases of the food consumption cycle and rank their contribution to waste. The results suggest that the more upstream the phase, the stronger the influence on food waste generation in homes. Purchasing emerges as the most critical choice of the consumers' food waste cycle. This gap between behavior and outcome adds uncertainty to food decisions, which reverberates on behavioral beliefs and as a result, leads consumers to resort to heuristics. The findings allow for the identification of a set of behavioral patterns with implications on food waste generation. Furthermore, purchasing decisions are exposed to out-of-home contextual factors, suggesting that food retail can affect consumer behaviors relevant to household food waste.
