Abstract: | 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). Results from Principal and Simultaneous Component Analyses showed a unidimensional structure of the EAT-26 item scores. Reliability analyses supported the internal consistency of the scale. Study 1 also explores the ability of the EAT-26 to discriminate between subjects with Eating Disorder (ED), Symptomatic or Asymptomatic by means of ROC analyses and using results from the Questionnaire for Eating Disorder Diagnoses (Q-EDD; Mintz, O'Halloran, Mulholland, & Schneider, 1997) as criterion. The EAT-26 demonstrated good specificity but insufficient sensitivity to detect a full or partial ED. Study 2 explores the ability of the questionnaire to discriminate between subjects with and without ED. The EAT-26 demonstrated good specificity and moderate sensitivity to detect ED. Clinical and theoretical implications of these results are discussed. |
