Objective: To analyze the psychometric properties of the test EDI-2 to evaluate eating disorders in Chilean adolescents Method: The sample was constituted by 1,429 adolescents (595 men and 835 women) between 13 and 18 years from the city of Antofagasta, to whom the EDI-2 test was applied. The reliability and the validity of the instrument were evaluated by factorial analysis and t-test. Results: The majority of the dimensions and the total scale have alphas above 0.70. Factorial structure observed was similar to the theoretical proposal. Conclusions: The EDI-2 test with corrections applied to Chilean population is a reliable and valid instrument for use as a screening tool in early detection of eating disorders.
