Self-Assessment Questionnaire

Personal Health Design (PhD) Screening Tool

Our PhD is a health questionnaire that will help you assess your digestive status. It is not meant as a replacement for a physician’s care. This questionnaire will help you discover where your digestive system may be having problems. It is a screening tool only and does not constitute a diagnosis of your problem. However, it can point you in the right direction in determining where the highest priorities lie in your healing process.

0 = Symptom is not present/rarely present
1 = Mild/sometimes
2 = Moderate/often
3 = Severe/almost always

Select the number which best describes the intensity of your symptoms. If you do not know the answer to a question, select “0”. Our experts will review your submission and you will receive recommendations based on your assessment within 48 hours.
