Health messages framed to be congruent with people's motivational orientation have been shown to be generally effective in promoting health behavior change, but some inconsistencies have been found. This study tested whether the perceived quality of a health message moderated the congruency effect in the domain of fruit and vegetable (FV) consumption. Undergraduate participants (N = 109) read a health message promoting FV intake in which the frame (gain vs. loss) was either congruent or incongruent with their approach/avoidance motivational orientation. Perceived message quality and intention to increase FV intake were assessed after message exposure, and self-reported FV intake was assessed one week later. A significant interaction between congruency and perceived message quality was found on both intention and FV intake. When messages were congruent, higher intentions and FV intake were observed when perceived message quality was high, but the reverse pattern was observed when perceived message quality was low. The findings support the potential utility of using congruently-framed messages to promote fruit and vegetable consumption, while also underscoring the necessity of using high-quality messages in order for congruency to influence health-related behaviors.
那些构建得与人们的动机取向相一致的健康信息，已被证明在促进健康行为改变方面总体上是有效的，但也发现了一些不一致之处。本研究测试了健康信息的感知质量是否会调节水果和蔬菜（FV）消费领域中的一致性效应。本科参与者（N = 109）阅读了一条促进FV摄入的健康信息，其中框架（获益与损失）与他们的趋近/回避动机取向一致或不一致。在接触信息后评估感知到的信息质量和增加FV摄入的意图，并在一周后评估自我报告的FV摄入量。在意图和FV摄入量方面，一致性和感知到的信息质量之间都存在显著的交互作用。当信息一致时，感知到的信息质量高时会观察到更高的意图和FV摄入量，但当感知到的信息质量低时则观察到相反的模式。这些发现支持了使用一致框架的信息来促进水果和蔬菜消费的潜在效用，同时也强调了使用高质量信息以使一致性影响健康相关行为的必要性。
