Such interventions would have the potential to reduce the prevalence of chronic pain in the population .
Although certain risk factors can identify individuals who are most likely to develop chronic pain , few interventions to prevent chronic pain have been identified .
To facilitate the identification of preventive interventions , an IMMPACT meeting was convened to discuss research design considerations for clinical trials investigating the prevention of chronic pain .
We present general design considerations for prevention trials in population s that are at relatively high risk for developing chronic pain .
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
