As a measure of restrained eating, Herman's Restraint Scale (1978) reliably predicts laboratory food consumption in college students regardless of their weight. However, the generality and psychometric properties of the scale have not been established. In the present study, 136 male and female adults were cross-classified as obese and normal and as dieting or non-dieting. The subjects were administered a single questionnaire containing items of the Lie, Social Desirability, and Restraint scales presented in randomized order. Unlike previous reports by Herman, the three adult groups differed significantly on the Restraint Scale in the following order: Obese dieters greater than Obese non-dieters greater than normals. Also, alpha reliability coefficients varied across groups and corrected item-total correlations also displayed considerable variability with no uniformity apparent for individual item correlations. The factor analysis identified three factors within the ten item scale, and for the obese dieters, the scale was not independent of social desirability. These results indicate that the Restraint Scale has limited usefulness beyond laboratory settings with college students.
作为衡量节制饮食的一种方法，赫尔曼的节制量表（1978年）能够可靠地预测大学生在实验室中的食物摄入量，无论其体重如何。然而，该量表的普遍性和心理测量特性尚未得到证实。在本研究中，136名成年男女被交叉分类为肥胖和正常，以及节食或非节食。受试者接受了一份单一问卷，其中包含说谎、社会赞许性和节制量表的项目，这些项目以随机顺序呈现。与赫尔曼之前的报告不同，这三个成年组在节制量表上的差异显著，顺序如下：肥胖节食者大于肥胖非节食者大于正常人。此外，阿尔法信度系数在不同组之间有所不同，校正后的项目总分相关性也显示出相当大的变异性，单个项目的相关性没有明显的一致性。因子分析在十个项目的量表中识别出三个因子，对于肥胖节食者来说，该量表与社会赞许性并非独立。这些结果表明，节制量表在大学生实验室环境之外的用途有限。
