Additional scales have indeed been added to the MMPI-2 to assess vulnerability to eating disorders, substance abuse, and poor functioning at work. However, option A is incorrect; the original MMPI was developed by administering a large group of inventory items to several different groups of people, including both clinical and nonclinical populations.
