The 26-item Eating Attitudes Test (EAT-26) is used to identify eating disturbances in non-clinical populations. The present study examined the construct validity of a screening version of EAT-26. The EAT-26 was administered to 2104 college students and their data were factor analyzed. The initial Alpha solution was rotated with orthogonal and oblique solutions. The analysis produced 5 factors that accounted for 57.4% of the total variance. The first principle component accounted for 61.3% of the total factor variance. The other 4 factors accounted for the remaining 38.7%. The factor 1 items with orthogonal loadings > 0.6 were retained resulting in a 10-item EAT (EAT-10). The Chronbach alpha reliability estimates of EAT-26 and EAT-10 were 0.897 and 0.952. The correlation between EAT-10 and EAT-26 was 0.92. The EAT-10 was directly correlated with age (i=0.14), BMI (r=0.19), percent body fat (r=0.19), and inversely correlated with VO 2 m a x (r=-0.16). The EAT-10 was re-administered to a new sample of college students (n = 1776). These data, combined with the data from the original sample, were used to establish population norms (n = 3880). These data show the EAT-10 is a highly internal consistent measure of the principal EAT construct and has promise of being a valid eating disorder screening test. Additional calibration research is underway to develop probability models for estimating the risk of the presence of eating disorders in a non-clinical population.
