EmetQ-13 is meant to measure the severity of symptoms. The range of scores is 13 to 65. Any score above 22 is normally a diagnosis of emetophobia. This instrument also has three sub-scales:
§  Items 1-6 indicate avoidance of travel and places where no help is available
§  Items 7-9 indicate how dangerous the patient believes exposure to vomit is
§  Items 10-13 indicate avoiding other people who may vomit
If clinicians administer one of these inventories, they can do an objective assessment pre- and post-treatment, and, if desired, at a 6-month or 12-month follow-up.
