Table 2.

(a) Regression models for the prediction of emotion recognition threshold, including demographic variables (age, IQ and depression) in the first step, alexithymia, measured by the TAS-20 in the second step, and ED symptomology, measured by the EDE-Q in the third. (b) Regression models including demographic variables in the first step, ED symptomology in the second step, and alexithymia in the third. (Both hierarchical regressions indicate that alexithymia does, and ED symptomology does not, predict emotion recognition threshold over and above demographic variables, regardless of the order they were entered into the regression model.)
