EATING ATTITUDES TEST

Supplemental Materials for:

The Eating Attitudes Test-26 Revisited using Exploratory Structural Equation Modeling (ESEM)

These online supplements comprise three sections, including:

(1)  Studies on the factorial structure of EAT-26 in nonclinical samples of adolescents

(2)  Six-Factor EFA solution for the initial 26-item version of the EAT

(3)  Goodness of fit indices of the measurement invariance tests conducted on the EAT-18 Models

(4)  Conversion of raw scores of the EAT-18 items to percentile ranks with 95% two-sided interval estimates in the total sample (n = 1779).

(5)  Conversion of raw scores of the EAT-18 items to percentile ranks with 95% two-sided interval estimates in the girls sample (n = 1006).

(6)  Conversion of raw scores of the EAT-18 items to percentile ranks with 95% two-sided interval estimates in the boys sample (n = 773).
