Symptom and Safety Behavior Checklist
This is the section on safety behaviors only from the above document which can be given to patients to fill out.
EmetQ-13
The EmetQ-13 is designed to measure the severity of symptoms. Further info can be found here. The range of scores is 13-65. Scores above 22 are normally considered as diagnostic of emetophobia.
The assessment has three subscales.
Items 1-6 indicate avoidance of travel and places where help isn’t readily available.
Items 7-9 indicate how dangerous exposure to vomit feels to the patient
Items 10-13 indicate avoiding others
SPOVI
Below is the Specific Phobia of Vomiting Inventory (SPOVI). A score above 10 is considered a likely diagnosis of emetophobia. Information on the development of the scale can be found here.
Y-BOCS
You can find a good page with the Y-BOCS (OCD) assessment here. The webpage will calculate the assessment scores and give a severity rating. There is good explanation for it as well.
