Studies indicate that various measures of dietary restraint show inconsistent relations to bulimic symptomatology. The present study tested the assertion that this is because the scales differ in the extent to which they reflect the success or failure of dietary efforts. This study also tested the competing hypothesis that criterion confounding of the Restraint Scale produced the inconsistent findings. Data from 117 undergraduates indicated that both the Restraint Scale and the Dutch Restrained Eating Scale were correlated with bulimic pathology, but that the magnitude to the relations were higher for the former. These results supported the dietary success failure hypothesis, however, this difference disappeared when the two disinhibited eating items from the Restraint Scale were deleted. Thus, the inconsistent findings in prior research appear to be due to the criterion confounding of the Restraint Scale. Implications for the measurement of restraint are discussed.
研究表明，各种饮食限制的测量方法与贪食症状学之间的关系并不一致。本研究检验了这样一种说法，即这是因为这些量表在反映饮食努力的成功或失败程度上存在差异。本研究还检验了一个相互竞争的假设，即克制量表的标准混淆导致了不一致的结果。来自117名本科生的数据表明，克制量表和荷兰克制饮食量表都与贪食病理相关，但前者的相关程度更高。这些结果支持了饮食成功失败假设，然而，当从克制量表中删除两个去抑制饮食项目时，这种差异就消失了。因此，先前研究中不一致的结果似乎是由于克制量表的标准混淆。文中讨论了对克制测量的影响。
