This screener is based on the DePaul Symptom Questionnaire, a validated instrument meant to assess ME/CFS symptomatology. It is broken up into 3 stages and prompts the user to continue if their responses meet the threshold scores for the case definitions of ME/CFS.
This online screener was developed by Sage Benner and Paul Cathey at DePaul's Center for Community Research. To report technical issues or to provide design-related feedback, contact Paul at pcathey AT depaul.edu.
