ABSTRACT

Food waste is a significant environmental, economic, and social issue contributing to global warming. The benefits of theoretically informed programs have been verified in psychology, social science, and education, yet our understanding of theory application in food waste behaviour change is scarce. To understand how food waste can be reduced, we need to understand what works, when, where and why. Assessing the extent of theory use in the context of food waste behaviour is needed to advance progress. Following the approach employed in Willmott et al. (2019) this study sought to assess the extent of theory application in studies aiming to reduce household food waste. A systematic search and review of published studies concerning household food waste behaviour was conducted. Of 3,532 studies, nine studies met the inclusion criteria. Eight studies mentioned a theory, however, the association between program strategies implemented and the theory base reported was lacking. This review concludes there is considerable room for improvement in theory reporting to indicate clearly how theory is applied to reduce household food waste behaviour.

摘要

食物浪费是导致全球变暖的重大环境、经济和社会问题。理论知识计划的好处已在心理学、社会科学和教育领域得到验证，但我们对理论应用在食物浪费行为改变方面的理解却很少。要了解如何减少食物浪费，我们需要了解有效的方法、时间、地点和原因。需要评估理论在食物浪费行为背景下的应用程度，以推动进展。按照 Willmott 等人采用的方法。(2019) 这项研究旨在评估理论在旨在减少家庭食物浪费的研究中的应用程度。对有关家庭食物浪费行为的已发表研究进行了系统搜索和审查。在 3,532 项研究中，有 9 项研究符合纳入标准。八项研究提到了一个理论，但是，实施的计划策略与报告的理论基础之间的关联是缺乏的。这篇综述得出结论，理论报告有很大的改进空间，可以清楚地表明理论是如何应用于减少家庭食物浪费行为的。
