Thirty female anorectics (mean age 26.4) and 30 female college student controls (mean age 25.3) completed a multidimensional locus of control scale, the Structural Family Interaction Scale, The Eating Attitudes Test, and a global clinical assessment measure. Three variables associated with Minuchin, Rosman, and Baker's (1978) family systems theory (overprotection, enmeshment, and rigidity) and one related to Bruch's (1973) theoretical position on anorexia nervosa (locus of control) were contrasted in terms of their relative effectiveness in predicting both the presence or absence and severity of the disorder. The best predictor of both measures in a series of regression and discriminant function analyses was locus of control orientation. The anorectics were significantly more external than the controls. The two groups did not differ on any of the family variables central to Minuchin et al.'s theory. The results support Bruch's contention that underlying anorexia nervosa is a sense of personal ineffectiveness.
30名女性厌食症患者（平均年龄26.4岁）和30名女性大学生对照组（平均年龄25.3岁）完成了一项多维控制点量表、结构家庭互动量表、饮食态度测试以及一项整体临床评估指标。将与米努钦、罗斯曼和贝克（1978年）的家庭系统理论相关的三个变量（过度保护、情感卷入和僵化）以及一个与布鲁赫（1973年）关于神经性厌食症的理论立场相关的变量（控制点）在预测该疾病的存在与否及严重程度方面的相对有效性进行了对比。在一系列回归分析和判别函数分析中，这两项指标的最佳预测因素是控制点取向。厌食症患者的外控性显著高于对照组。两组在米努钦等人理论的任何核心家庭变量上均无差异。研究结果支持了布鲁赫的观点，即神经性厌食症的潜在根源是个人效能感缺失。
