Soft drink consumption has become a major public health issue. The present study aimed to examine the role of rash impulsivity and reward sensitivity in soft drink consumption using the two-factor model of impulsivity. Participants were a community sample of 229 adults (19-77 years). They completed self-report measures of impulsivity (SUPPS-P), reward sensitivity (RST-PQ) and beverage consumption (BEVQ-15). A principal component analysis was used to produce purer measures of rash impulsivity and reward sensitivity. Both rash impulsivity and reward sensitivity were positively associated with soft drink consumption, and each independently predicted soft drink consumption. Importantly, there was a significant interaction between the two, whereby rash impulsivity moderated the effect of reward sensitivity on soft drink consumption. The results support the logic of the two-factor model of impulsivity in the prediction of soft drink consumption. Further research should extend these findings to other consumption domains in both clinical and non-clinical populations.
软饮料消费已成为一个主要的公共卫生问题。本研究旨在使用冲动的双因素模型来检验冲动性和奖赏敏感性在软饮料消费中的作用。参与者是一个由 229 名成年人（19-77 岁）组成的社区样本。他们完成了冲动性的自我报告测量（SUPPS-P）、奖赏敏感性（RST-PQ）和饮料消费（BEVQ-15）。主成分分析用于产生更纯粹的冲动性和奖赏敏感性测量。冲动性和奖赏敏感性都与软饮料消费呈正相关，并且各自独立地预测软饮料消费。重要的是，两者之间存在显著的交互作用，即冲动性在一定程度上调节了奖赏敏感性对软饮料消费的影响。研究结果支持冲动的双因素模型在预测软饮料消费中的逻辑。进一步的研究应该将这些发现扩展到临床和非临床人群的其他消费领域。
