本研究探讨了描述性规范信息的影响，无论是传达大学生吃足够量的水果和蔬菜（F&V），或者他们不，F&V消费，以及是否有任何影响是由学生身份缓和。采用在线2（标准：“足够”/“不足”）× 2（鉴别：“低”/“高”）实验设计。提供了包含“充足”/“不足”F&V摄入量描述性规范的信息图。一个标识操作被用来创建“高”/“低”学生标识符。F&V摄入意图进行评估后的操作，自我报告的F&V摄入量在干预后2天。英国的本科生（N = 180）报告了他们的摄入意图，其中112人（62%）完成了行为随访。参与者主要是来自苏格兰大学的白色女性学生，平均年龄20.4（±1.6）岁。基线平均F&V消耗量较高（4.5 ± 2.8）。规范或身份操纵对F&V意图和摄入没有显著的主效应。在随访时，水果摄入意图和蔬菜摄入量显示出显著的规范×识别相互作用，表明组间的半份差异（~40 g）。具有讽刺意味的效果被观察到的“高”标识符，谁不打算，也没有按照组规范行事;“低”学生标识符打算和遵循组规范，其中“足够”/“低”组打算消费更多的水果部分和消费更多的蔬菜比“不足”/“低”组。鉴于规范×认同交互作用导致的组间半部分差异，未来有必要对更大样本的低F&V摄入量的年轻人进行研究，以进一步探索观察到认同调节效应的条件及其潜在机制。
This study investigated the influence of descriptive norm messages that either communicated that university students eat a sufficient amount of fruit and vegetable (F&V) or that they do not, on F&V consumption, and whether or not any effects are moderated by student identification. An online 2 (Norm: “Sufficient”/“Insufficient”) × 2 (Identification: “Low”/“High”) experimental design was employed. Infographics containing “sufficient”/“insufficient” F&V intake descriptive norms were presented. An identification manipulation was employed to create “high”/“low” student identifiers. F&V intake intentions were assessed after the manipulations; self-reported F&V intake was reported at 2 days post-intervention. Undergraduate students in the United Kingdom (N = 180) reported their intake intentions, of which 112 (62%) completed the behavioral follow-up. Participants were predominantly white female students from Scottish universities, mean age 20.4 (±1.6) years. Baseline mean F&V consumption was high (4.5 ± 2.8). There were no significant main effects of Norm or Identification manipulations on F&V intentions and intake. Significant norm × identification interactions were revealed for fruit intake intentions and vegetable intake at follow-up, indicating half-portion differences (~40 g) between groups. Ironic effects were observed for “high” identifiers, who neither intended to, nor acted in accordance with group norms; “low” student identifiers intended to and followed group norms, whereby the “sufficient”/“low” group intended to consume significantly more fruit portions and consumed more vegetables than the “insufficient”/“low” group. Given the half-portion differences between groups resulting from the norm × identification interactions, future research on a larger sample of young adults with low F&V intake is warranted to further explore the conditions under which moderating effects of identification are observed and the underlying mechanisms.
