Approximately one quarter of the food supplied in the world is wasted across the food supply chain. Almost half of this amount is related to household food waste, which results from mis-management of consumption. Therefore, the purpose of this study was to investigate the consumer food management behavior in order to reduce food waste. Survey data were gathered among 405 Iranian respondents who were responsible for food preparation in their households and were aged from 15 to 64 years old, by using an extended theory of planned behavior (TPB). In addition to measuring the constructs of planned behavior theory, the feeling of guilt construct was incorporated to the model. The extended model was derived and examined through structural equation modeling (SEM). Results showed the usefulness of using the extended model of planned behavior in predicting intention to reduce food waste and food consumption management. Moreover, attitude, perceived behavioral control, feeling of guilt, subjective norm and intention of not wasting food were the drivers of managing food consumption and avoiding food waste. Besides, results showed that intention to reduce household food waste is predictable by attitude, subjective norm and feelings of guilt constructs. At the end, implications of the study for changing consumers' food management behavior are discussed.
在全球的食品供应链中，大约有四分之一的食品被浪费掉了。其中近一半的浪费与家庭食物浪费有关，这是由于消费管理不善造成的。因此，本研究旨在调查消费者的食品管理行为，以减少食物浪费。通过使用扩展的计划行为理论（TPB），对 405 名来自伊朗的负责家庭食品准备的年龄在 15 至 64 岁的受访者进行了调查，收集了调查数据。除了衡量计划行为理论的结构外，还将内疚感结构纳入到模型中。通过结构方程建模（SEM）推导出并检验了扩展模型。结果表明，在预测减少食物浪费和食物消费管理的意图方面，使用扩展的计划行为模型是有用的。此外，态度、感知行为控制、内疚感、主观规范和不浪费食物的意图是管理食物消费和避免食物浪费的驱动因素。此外，研究结果表明，减少家庭食物浪费的意图可以通过态度、主观规范和内疚感结构来预测。最后，讨论了该研究对改变消费者食品管理行为的意义。
