The homogeneity of the restraint construct is investigated in a study of 54,525 subjects participating in a weight reduction program. Using the German version of the TFEQ (Stunkard & Messick, 1985, Journal of Psychosomatic Research, 29, 71-83; Pudel & Westenhoefer 1989a, Fragebogen zum Essverhalten; Handanweisung), it is shown that different types of relations exist between the items measuring dietary restraint and the disinhibition scale. A discriminant analysis in a subgroup of moderately highly restrained eaters with either low or high disinhibition (n = 1759) reveals different sets of restraint behaviours and cognitions that differentiate between high and low disinhibition. These findings are replicated in an independent validation sample (n = 1693). Two restraint subscales are constructed, one associated with increasing disinhibition, the other with decreasing disinhibition. It is argued that different sets of restrained behaviours and cognitions should be differentiated when looking at the causal link between restraint and disturbances of eating behaviour.
在一项针对54525名参与减肥计划的受试者的研究中，对节食抑制结构的同质性进行了调查。使用德文版的三因素饮食问卷（TFEQ）（斯图卡德和梅西克，1985年，《身心研究杂志》，29卷，71 - 83页；普德尔和韦斯特霍费尔，1989年a版，《饮食行为问卷；使用说明》），结果表明，测量饮食抑制的项目与去抑制量表之间存在不同类型的关系。对一组中度高度节食者（去抑制程度低或高，n = 1759）进行的判别分析揭示了区分高去抑制和低去抑制的不同节食行为和认知模式。这些发现在一个独立的验证样本（n = 1693）中得到了重复。构建了两个节食分量表，一个与去抑制增加相关，另一个与去抑制减少相关。有人认为，在研究节食与饮食行为紊乱之间的因果关系时，应该区分不同的节食行为和认知模式。
