If a dimensional measure of frequency of binges and purges are used for cases of Bulimia Nervosa, a statistically significant effect would have been observed, demonstrating that the diagnostic treatment is more effective in low-risk than that of high-risk groups. If this were categorical, CBT would be seen as ineffective as a treatment. A statistical perspective portrays the advantages of using dimensional over categorical results provide greater overview to perceive greater treatment effects, accuracy in estimates within a cohort, and better ability to detect symptoms in determining a diagnosis. Inconsistencies and theoretical weaknesses are inherent in the current DSM since most ED patients are largely atypical. In the
