Although a variety of pain and physical functioning outcome measures have been reported in the literature , few have demonstrate method ologically strong psychometric properties .
INTRODUCTION A range of outcome measures across various domains are used to evaluate change following an intervention in clinical trials on chronic neuropathic pain ( NeP ) .
However , to capture a real change in the variable of interest , the psychometric properties of a particular measure should demonstrate appropriate method ological quality .
Various outcome measures in the domains of pain and physical functioning have been used in the literature for NeP , for which individual properties ( eg , reliability/validity ) have been reported .
Development and initial validation of an expanded and revised version of the Short-form McGill Pain Questionnaire (SF-MPQ-2)
ABSTRACT The objective of the present research was to develop a single measure of the major symptoms of both neuropathic and non‐neuropathic pain that can be used in studies of epidemiology , natural history , pathophysiologic mechanisms , and treatment response . We exp and ed and revised the Short‐form McGill Pain Question naire1 ( SF‐MPQ ) pain descriptors by adding symptoms relevant to neuropathic pain and by modifying the response format to a 0–10 numerical rating scale to provide increased responsiveness in longitudinal studies and clinical trials . The reliability , validity , and subscale structure of the revised SF‐MPQ ( SF‐MPQ‐21 )  were examined in responses from 882 individuals with diverse chronic pain syndromes and in 226 patients with painful diabetic peripheral neuropathy who participated in a r and omized clinical trial . The data suggest that the SF‐MPQ‐2 has excellent reliability and validity , and the results of both exploratory and confirmatory factor analyses provided support for four readily interpretable subscales — continuous pain , intermittent pain , predominantly neuropathic pain , and affective descriptors . These results provide a basis for use of the SF‐MPQ‐2 in future clinical research , including clinical trials of treatments for neuropathic and non‐neuropathic pain conditions
