Invariance of the Eating Disorder Inventory-Drive for Thinness subscale across university and community samples.

The Eating Disorder Inventory-Drive for Thinness (EDI-DT) subscale is commonly used in research and as an eating disorder screening measure, but extant evidence is scant regarding its psychometric properties. University and community samples often are treated as interchangeable in terms of research conclusions. Given established demographic differences between these two populations, the present study tested measurement invariance of the EDI-DT across these two sample types.
