为了响应呼吁，以扩大消费者愿意减少肉类消费和采取更多的植物性饮食的知识，这项工作的建设，肉类附件和肉类附件问卷（MAQ）。MAQ是一个新的衡量标准，指的是对肉类消费的积极联系。它是通过三个连续的研究开发和验证的，从深入的方法消费者代表的肉类。项目的构建和初始池首先是根据先前关于消费者对肉类的评价的工作中410名参与者的定性数据开发的。之后，1023名参与者完成了这些项目和其他措施，提供数据来评估项目选择，因素结构，信度，收敛和并发效度，预测能力。最后，来自不同文化背景的318名参与者完成了MAQ的最终版本沿着其他措施，以评估测量的不变性，可靠性和预测能力。在样本中，四因素解决方案（即，享乐主义，亲和力，权利，和依赖）与16个项目和二阶整体尺寸的肉类附件完全符合标准的良好模型拟合。MAQ分量表和全球尺度与对肉类的态度、主观规范、人类至上信仰、饮食习惯和饮食认同相关。他们还提供了额外的解释方差以上的核心TPB变量（即态度，主观规范和感知行为控制）的意愿和意图有关肉类替代品。总的来说，研究结果指出了MAQ与肉类消费和肉类替代研究的相关性，并支持了这样一种观点，即对肉类的依恋模式可能会阻碍向更植物性饮食的转变。(C)2015爱思唯尔有限公司版权所有。
In response to calls to expand knowledge on consumer willingness to reduce meat consumption and to adopt a more plant-based diet, this work advances the construct of meat attachment and the Meat Attachment Questionnaire (MAQ). The MAQ is a new measure referring to a positive bond towards meat consumption. It was developed and validated through three sequential studies following from an in-depth approach to consumer representations of meat. The construct and initial pool of items were firstly developed drawing on qualitative data from 410 participants in a previous work on consumers' valuation of meat. Afterwards, 1023 participants completed these items and other measures, providing data to assess item selection, factor structure, reliability, convergent and concurrent validity, and predictive ability. Finally, a sample of 318 participants from a different cultural background completed the final version of the MAQ along with other measures to assess measurement invariance, reliability and predictive ability. Across samples, a four-factor solution (i.e., hedonism, affinity, entitlement, and dependence) with 16 items and a second-order global dimension of meat attachment fully met criteria for good model fit. The MAQ subscales and global scale were associated with attitudes towards meat, subjective norm, human supremacy beliefs, eating habits, and dietary identity. They also provided additional explanatory variance above and beyond the core TPB variables (i.e. attitudes, subjective norm and perceived behavioral control) in willingness and intentions concerning meat substitution. Overall, the findings point towards the relevance of the MAQ for the study of meat consumption and meat substitution, and lend support to the idea that holding a pattern of attachment towards meat may hinder a shift towards a more plant-based diet.
