This study investigated the construct validity of two dietary restraint subscales, flexible control (FC) and rigid control (RC), identified by Westenhoefer (1991; Appetite, 16, 45-55) as a subset of the restraint scale items from the Three-Factor Eating Questionnaire (TFEQ, Stunkard & Messick. [1985]. Journal of Psychosomatic Research, 29, 71-83). The subjects were 31 women on long-term personality disorder units. Based on the Structured Clinical Interview for DSM-III-R (SCID), 68% has past anorexia and/or bulimia diagnoses and 94% were borderline. The subjects completed the TFEQ and supplied weight and height data for body mass index (BMI) calculations. The results supported the validity of the two restraint constructs by showing that FC was inversely related to BMI and predicted an anorexia diagnosis. In contrast, RC directly predicted BMI when tested concurrently with FC. RC was also more associated with a history of bulimia and problems with weight fluctuations than FC was. Thus, the FC-RC distinction was valid and useful in this population of women.
本研究调查了两种饮食克制分量表的结构效度，即灵活控制（FC）和严格控制（RC），这两种分量表由韦斯特霍费尔（1991年；《食欲》，第16卷，第45 - 55页）从三因素饮食问卷（TFEQ，斯唐卡德和梅西克，[1985年]。《身心研究杂志》，第29卷，第71 - 83页）的克制量表项目中识别出来。研究对象为31名长期住在人格障碍病房的女性。根据《精神疾病诊断与统计手册第三版修订本》结构化临床访谈（SCID），68%的人曾被诊断患有厌食症和/或贪食症，94%的人处于边缘状态。研究对象完成了TFEQ问卷，并提供了体重和身高数据用于计算体重指数（BMI）。结果支持了这两种克制结构的效度，表明FC与BMI呈负相关，并可预测厌食症诊断。相比之下，在与FC同时进行测试时，RC直接预测BMI。与FC相比，RC也与贪食症病史和体重波动问题更相关。因此，FC - RC的区分在这群女性中是有效且有用的。
