To address the problem of malnutrition in poor rural areas of China, this study aims to examine the effects of social-psychological factors in food consumption of rural residents in poor counties of Southwest China. In addition, it investigates the role of perceived need and habit within the theory of planned behavior (TPB) in predicting food consumption. A survey with random sampling was conducted on rural residents ( = 424), and the theoretical frameworks of both the standard and extended TPB were applied for comparison purposes. Structural equation modeling was applied to test the relationships among constructs. Consumption of five food items was studied, respectively: meat, eggs, dairy, fish, and fruits. Results showed that incorporation of perceived need and habit substantially increased the explanatory power of the TPB, but these factors only had significant direct effects on intention rather than behavior. Perceived need and habit are stronger predictors of intention than any other TPB construct for consumption of all food items except for meat. We found indirect effects of the constructs in the extended TPB model on consumption to be different across food items. Practical implications to improve consumption of different food items were proposed accordingly.
为解决中国贫困农村地区的营养不良问题,本研究旨在探讨社会心理因素对中国西南贫困县农村居民食物消费的影响。此外,还调查了计划行为理论(TPB)中感知需求和习惯在预测食物消费方面的作用。本研究采用随机抽样对农村居民(n=424)进行了调查,并应用了标准和扩展 TPB 的理论框架进行比较。采用结构方程模型检验了各构念之间的关系。分别研究了五种食物的消费情况:肉类、蛋类、乳制品、鱼类和水果。结果表明,纳入感知需求和习惯可显著提高 TPB 的解释力,但这些因素仅对意图而不是行为有显著的直接影响。感知需求和习惯是所有食物消费的意图比 TPB 其他任何构念更有力的预测因素,除了肉类。我们发现,扩展 TPB 模型中各构念对不同食物消费的间接影响是不同的。相应地提出了改善不同食物消费的实际意义。
