The construct validity of Herman and Polivy's Restraint Scale (RS), the restraint factor of the Three Factor Eating Questionnaire (TFEQ-R), and the restraint scale of the Dutch Eating Behavior Questionnaire (DEBQ-R) were investigated by relating these scales to self-reported mean caloric intake per day and to other measures associated with disordered eating and figure consciousness. A factor analysis showed that the three restraint scales measure different components of the restraint construct. A high score on the RS was closely related to consequences of mostly unsuccessful dieting, such as disinhibited eating and weight fluctuations, but not to successful overall caloric restriction in everyday life. High scores on the TFEQ-R and the DEBQ-R represented the more successful dieting behavior component of restraint. The three scales have in common a motivational component of restrained eating, including concerns about shape and weight, and desire for thinness.
通过将赫尔曼和波利维的节食量表（RS）、三因素饮食问卷（TFEQ-R）中的节食因子以及荷兰饮食行为问卷（DEBQ-R）中的节食量表与自我报告的每日平均热量摄入以及与饮食失调和身材意识相关的其他指标相关联，对这些量表的结构效度进行了研究。一项因素分析表明，这三个节食量表测量了节食结构的不同组成部分。RS得分高与大多不成功节食的后果密切相关，如饮食失控和体重波动，但与日常生活中成功的总体热量限制无关。TFEQ-R和DEBQ-R得分高代表了节食行为中更成功的部分。这三个量表的共同之处在于存在节食的动机成分，包括对身材和体重的关注以及对瘦的渴望。
