Validation of Pain Severity Assessment using the PainDETECT Questionnaire

Abstract

Background: The PainDETECT Questionnaire (PD-Q) is a screening tool for Neuropathic Pain (NeP). A cutoff value of ≥ 13 indicates the possibility of NeP components. The PD-Q score seems to reliably distinguish the severity of NeP; however, it has not yet been validated whether changes of the PD-Q score can follow changes of pain severity assessed using an 11-point Numerical Rating Scale (NRS).
