This paper focuses on the validation of the Spanish form of the Eating Attitudes Test (EAT-26; Garner, Olmsted, Bohr & Garfinkel, 1982) across two studies. Participants in Study 1 were 778 females recruited from community settings (aged 12-21). Study 2 included 86 females recruited from clinical and 86 females from community settings (aged 12-35).

The Eating Attitudes Test-40 (EAT-40; Garner & Garfinkel, 1979) is one of the most widely used measures in the field of eating disorders (ED). The factor structure of the EAT-40, as well as the optimal cut-off score to identify subjects with ED, are subjects of debate. Both controversial issues are addressed in the present study. Participants were 95(More)
A new procedure based on partition of the unity has been developed to construct spatial approximation-prediction functions for discrete density functions. This Partition of the Unity Procedure (PUP) provides a family of approximation-prediction functions which depends on several parameters. In order to find the best function we have considered error(More)
The authors derive a general equation to compute multiple cut-offs on a total test score in order to classify individuals into more than two ordinal categories. The equation is derived from the multinomial logistic regression (MLR) model, which is an extension of the binary logistic regression (BLR) model to accommodate polytomous outcome variables. From(More)
The closed model category of exterior spaces, that contains the proper category, is a useful tool for the study of non compact spaces and manifolds. The notion of exterior weak N-S-equivalences is given by exterior maps which induce isomorphisms on the k-th N-exterior homotopy groups π N k for k ∈ S, where S is a set of non negative integers. The category(More)
