'I know it's changed': a mixed-methods study of the meaning of Global Perceived Effect in chronic neck pain patients.

摘要

GPE appears to capture chronic neck pain patient perceptions of change in different domains important to their individual pain experiences that may not be captured by other outcome instruments. Thus, GPE is a suitable patient-oriented outcome that can complement other measures in research and clinical practice. Importantly, many chronic neck pain patients believe it impossible to reach complete recovery because of a perceived intractable aspect of their neck condition; this has important implications regarding long-term disability and health-seeking behaviors.
