Defining and measuring such qualities as restrained eating or dieting may require more than simply administering questionnaires and assuming that we are identifying the population that we wish to study. Different questionnaires may identify different types of restrained eaters, and even deciding what restrained eating consists of is a complicated endeavor. We discuss how to define and measure restrained eating, specifying key attributes, and acknowledging the problems inherent in relying on self-report instruments. We conclude that given the difficulties in defining such constructs as restrained eating, we need to specify more clearly exactly what our research questions are, in order to be sure that we are identifying the populations with the attributes necessary to answer those questions.
定义和衡量诸如节制饮食或节食等特质，可能不仅仅是简单地发放问卷并假定我们所确定的就是我们想要研究的人群。不同的问卷可能会识别出不同类型的节制饮食者，甚至确定节制饮食的构成都是一项复杂的工作。我们讨论了如何定义和衡量节制饮食，明确关键属性，并认识到依赖自我报告工具所固有的问题。我们得出结论，鉴于在定义诸如节制饮食这样的概念时存在困难，我们需要更明确地具体说明我们的研究问题是什么，以便确保我们所确定的人群具备回答这些问题所需的属性。
