Demographic analysis.

Food intolerances, allergies, and celiac disease cause hypersensitive reactions to certain foods, collectively termed adverse reactions to food. This study aims to identify predictors of purchasing intentions and behaviors among individuals with such reactions, using three behavioral models: the Theory of Planned Behavior, the Health Belief Model, and Protection Motivation Theory. The authors created a new, comprehensive model by integrating these theories, combining their strengths to provide a more robust framework. The survey, conducted via the Forthright platform using the Computer-Assisted Web Interview (CAWI) method, involved 1,088 respondents. This article is the first to explore predictors of consumer intentions and behaviors regarding food products suitable for individuals with intolerances or allergies, offering new insights into consumer decision-making models.

食物不耐受、食物过敏与乳糜泻（celiac disease）会引发人体对特定食物的超敏反应，此类反应统称为食物不良反应（adverse reactions to food）。本研究旨在识别此类反应人群的购买意愿与购买行为的预测因子，采用了三种经典行为模型：计划行为理论（Theory of Planned Behavior）、健康信念模型（Health Belief Model）以及保护动机理论（Protection Motivation Theory）。研究者整合上述三种理论，结合各自优势构建了全新的综合模型，以搭建更为稳健的分析框架。本调研依托Forthright平台，采用计算机辅助网络访谈（Computer-Assisted Web Interview, CAWI）方法开展，共纳入1088名受访者。本文为首篇针对不耐受或过敏人群适配食品的消费者意愿与行为预测因子展开研究的学术成果，为消费者决策模型研究提供了全新视角。
