    ABSTRACT: The nosology for eating disorders, despite having been extensively revised over time, may not capture the natural clustering of eating-related pathology as it occurs in general population samples. Detailed information about anorectic and bulimic behaviors was assessed through personal interviews of 2,163 Caucasian female twins from a population-based registry. Latent class analysis was applied to nine eating disorder symptoms to develop an empirically based typology. Demographic, comorbidity, personality, and co-twin diagnosis data were used to validate the resultant classes. A six-class solution provided the best fit. One class displayed distorted eating attitudes without low body weight. Two classes demonstrated low weight without the psychological features of eating disorders. Three classes broadly resembled the DSM-IV classifications of anorexia nervosa, bulimia nervosa, and binge-eating disorder. For all classes, and especially for the three that reflected current diagnoses of eating disorders, monozygotic twins resembled one another much more in terms of class membership than did dizygotic twins. The authors found within a community sample, and through an empirical method, classes of eating-related pathology that broadly resembled the current classifications of anorexia nervosa, bulimia nervosa, and binge-eating disorder. Additional classes were marked by either the psychological features of eating disorders or low body weight. Individuals in the three eating-disorder classes had similar personality profiles but displayed differences in symptom expression and co-twin risk for anorexia nervosa, bulimia nervosa, and obesity.

    ABSTRACT: Tested the validity of a Spanish version of the Eating Attitudes Test (EAT) among 78 female patients (mean age 16.8 yrs) with anorexia nervosa and a comparison group of 78 normal Ss paired according to age and social class. The difference between the mean scores of these groups was highly significant. The global validity coefficient was .61. The study of discriminant validity indicated the need to establish a cutoff point of 20, which permits a sensitivity of 91% and a specificity of 69.2%. The alpha reliability coefficient was 0.93. The factor analysis allowed the extraction of 3 factors that explain 41% of the variance. A significant correlation with the Beck Depression Inventory was established. At the reevaluation of 27 patients after their clinical remission, the scores on the EAT were within the normal range. (Spanish abstract) (PsycINFO Database Record (c) 2012 APA, all rights reserved)

    ABSTRACT: Differences in the variability of the judgements of body shape were studied in anorexic, bulimic, obese, and control subjects. The judgements of control subjects were found to be more accurate and less variable than those of the clinical groups, and the distribution of their scores was leptokurtic and almost symmetrical compared with the clinical groups' distributions of scores which were platykurtic and positively skewed. More clinical subjects than controls both underestimated or overestimated their body sizes by 15% or more. Significantly more variability was found among the scores of bulimics than anorexics and among the scores of the obese than the anorexics, but not between the obese and the bulimics, who showed the greatest variability of all. The results are discussed in terms of their consistency with other research findings and their significance for treatment.
