Predictive validity refers to the ability of a test to predict future behavior or outcomes, in this case, the likelihood of developing an eating disorder. The scale needs to be able to differentiate between those who are at risk and those who are not, which is a key aspect of predictive validity. External validity refers to the generalizability of results to other populations, interrater reliability refers to the consistency of ratings between different raters, and test-retest reliability refers to the consistency of scores over time. While these are important aspects of reliability and validity, they are not directly related to the ability of the scale to predict eating disorder likelihood.
