To determine the relationship between sustainable and healthy food shopping behavior comparing general motivation with the immediate intention to act.
We conducted an online survey of 144 staff at the Cork Institute of Technology, Ireland, using a questionnaire based on the Theory of Planned Behavior and the Self-Determination Theory to compute the Behavioral Intention score and the Relative Autonomy Index in relation to healthy and sustainable grocery shopping.
The intention to shop healthy food was higher ( < 0.001, Cohen's d = 0.56) than the intention to shop in a sustainable way. A significant intention-action gap was observed for both healthy ( < 0.001, Cohen's d = 0.97) and sustainable grocery shopping ( < 0.001, Cohen's d = 1.78). While there was a significant correlation ( < 0.001) between the longer-term motivations to act in a healthy and sustainable way, this association was not significant ( = 0.16) for the more short-term Behavioral Intention scores.
Health was identified as a more important driver for dietary behavior compared to sustainability. While longer-term motivation shows a stronger correlation between healthy and sustainable grocery shopping, short-term intentions do not follow this pattern as strongly. A significant intention-action gap exists for both, which is stronger for sustainability than for health.
通过比较一般动机与即刻行动意图，确定可持续和健康食品购物行为之间的关系。
我们对爱尔兰科克理工学院的144名员工进行了一项在线调查，使用基于计划行为理论和自我决定理论的问卷来计算与健康和可持续食品杂货购物相关的行为意图得分和相对自主指数。
购买健康食品的意图高于以可持续方式购物的意图（<0.001，科恩d值=0.56）。在健康食品（<0.001，科恩d值=0.97）和可持续食品杂货购物（<0.001，科恩d值=1.78）方面均观察到显著的意图-行动差距。虽然以健康和可持续方式行动的长期动机之间存在显著相关性（<0.001），但这种关联在更短期的行为意图得分方面并不显著（=0.16）。
与可持续性相比，健康被确定为饮食行为的更重要驱动因素。虽然长期动机在健康和可持续食品杂货购物之间显示出更强的相关性，但短期意图并没有如此强烈地遵循这种模式。两者都存在显著的意图-行动差距，其中可持续性方面的差距比健康方面的更强。
