Aspetti cognitivo-comportamentali dell'alimentazione. Verifica della validita discriminante e convergente della versione italiana del test DIET

Background. This study tries to verify the discriminating and convergent validity of the Italian version of the DIET test (Dieter's Inventory of Eating Temptations). Methods. The study, which involved a sample population of 250 subjects (65 obese and 185 non obese), was designed to verify the ability of the test to discriminate deviant eating behaviours, as well as to verify the existence of any convergence between the DIET scales and those of the EAT, MMPI and ASQ tests that are consistent with the data of published studies concerning the characteristics of subjects with eating disturbances. Results and conclusions. The results indicate that the Italian version of DIET is valid in terms of both its discriminatory and convergent capacities, and suggest that it could be used as a screening test for the identification of subjects who may be at risk for over-eating.
