The DSQ has demonstrated strong psychometric properties in terms of test-retest reliability and sensitivity/specificity, as well as construct, predictive, and discriminant validity.

The DSQ allows for a well-defined characterization of a patient’s illness and allows scientists and clinicians to improve diagnostic reliability when employing case definitions of ME and CFS.
