Abstract

In the present instrumental study, we sought to determine the evidence of validity of the scale of risk factors associated with eating disorders. It was carried out in a sample of 700 students between 9 and 12 years old. In the evidences of content validity obtained with judges' criteria, they suggest favorable results reported with the Aiken V (.93 for males and .91 for females). In the evidence of internal structure by means of confirmatory factor analysis according to the four-factor model, acceptable adjustment rates were found in males (x2 / df = 2.35, RMR = .049, GFI = -925, NFI = .901, PGFI = .802; RFI = .904; PNFI = .800) and for women (X2 / gl = 2.47; RMR = .046; NFI = .906; GFI = .913; RFI = .903; PGFI = .788; PNFI = .778). With respect to the reliability obtained with the Omega coefficient, values are found between .76 to .85 in males and .75 to .85 in females.
