Restrained eaters with high scores on the Perceived Self-Regulatory Success in Dieting Scale (PSRS) are more successful than low scorers in regulating their food intake. According to the theory of temptation-elicited goal activation (Fishbach, Friedman, & Kruglanski, 2003), they have become successful because, due to earlier repeated instances of successful self-control, they formed an associative link between temptations and thoughts of dieting. It is unclear, however, why they should have been more successful in earlier attempts at self-control than their unsuccessful counterparts. We examined whether trait impulsiveness plays a role by investigating the associations between dietary restraint, trait impulsiveness, and PSRS. Results showed that the interaction between dietary restraint and impulsiveness predicted dieting success: A lower level of impulsiveness was associated with greater dieting success among restrained eaters. These results suggest that restrained eaters who are less impulsive are more likely to become successful restrained eaters as identified with the PSRS.
在节食自我调节成功量表（PSRS）上得分较高的有约束的饮食者比得分较低的饮食者更能成功地调节自己的食物摄入量。根据诱惑引发目标激活理论（Fishbach、Friedman 和 Kruglanski，2003），他们之所以成功，是因为由于早期多次成功的自我控制，他们在诱惑和节食想法之间形成了一种联想。然而，他们为什么在早期的自我控制尝试中比不成功的人更成功还不清楚。我们通过调查饮食限制、特质冲动性和 PSRS 之间的关联，研究特质冲动性是否起作用。结果表明，饮食限制和冲动性之间的相互作用预测节食成功：较低的冲动性与限制饮食者的节食成功相关。这些结果表明，PSRS 识别的冲动性较低的限制饮食者更有可能成为成功的限制饮食者。
