Relationships between EAT and other measures
In order to demonstrate discriminant validity, the EAT was correlated with several other measures in the NC group. The Restraint Scale is an importantmeasure, in that it assesses degree of dieting behavior. Because of the possible similarity in constructs underlying the EAT and Restraint Scale, scores on the measures were correlated for a sample of43 NC females. A moderately low Pearson’s correlation (r= 0-28), P› 0.05) was obtained, showing an insignificant relationship between measures.
To determine whether the EAT simply reflectsdifficulties in controlling weight, the EAT was correlated with adult weight fluctuations for NC subjects (N=58, r =+ 0.17, P› 0.1). The EAT scores also showed insignificant correlations with extraversion(N=26, r= 0.30) P› 0.1) and neuroticism (N= 26, r= 0.10 P › 0.1) on the Eysenck Personality Inventory NCs. Thus, from these data, the EAT appears to measure specific symptoms that are found much more oftenin anorexic population than in others. Moreover, the scores on this test are not merely related to measures of dieting weight fluctuations, extraversion or neuroticiam.
Relationships between EATscore and prognosis
The EAT was administered to a small number of AN patients who had clinically recovered. These subjects showed scores in the normal range (N= 9, X = 11.4 s,D = 5.1) suggesting thatthe EAT is sensitive to clinical remission. Six of these patients had been administered the EAT while symptomatic for AN and at that time showed EAT scores that were comparable to the clinical AN group.Las relaciones entre EAT y otras medidas
Para demostrar la validez discriminante, el EAT se correlacionó con varias otras medidas en el grupo de Carolina del Norte. La Escala de restricción esuna medida importante, ya que evalúa el grado de comportamiento de dieta. Debido a la similitud posible en las construcciones que se basa la EAT y Escala de restricción, las puntuaciones en las...
