Most health decision-making models posit that deciding to engage in a health behavior involves forming a behavioral intention which then leads to actual behavior. However, behavioral intentions and actual behavior may not be functionally equivalent. Two studies examined whether decision-making factors predicting dietary behaviors were the same as or distinct from those predicting intentions. Actual dietary behavior was proximally predicted by affective associations with the behavior. By contrast, behavioral intentions were predicted by cognitive beliefs about behaviors, with no contribution of affective associations. This dissociation has implications for understanding individual regulation of health behaviors and for behavior change interventions.
大多数健康决策模型假定，决定采取一种健康行为涉及形成一种行为意图，然后这种意图会导致实际行为。然而，行为意图和实际行为在功能上可能并不等同。两项研究考察了预测饮食行为的决策因素与预测行为意图的因素是否相同或不同。实际饮食行为最直接地由与该行为的情感关联所预测。相比之下，行为意图则由对行为的认知信念所预测，情感关联并无作用。这种分离对于理解个体对健康行为的调节以及行为改变干预具有启示意义。
