UnlabelledPain is among the most common symptoms of cancer. Because cancer can occur at any age, it is imperative that pain assessment tools are valid for use across the adult lifespan. The Short-Form McGill Pain Questionnaire-2 (SF-MPQ-2) is a valid and reliable tool for the assessment of the multidimensional qualities of pain in people with chronic nonmalignant pain, but its psychometric properties in people with cancer pain and in older versus younger people require investigation. This study evaluated age differences in the validity, reliability, and use of the SF-MPQ-2 in 244 people with advanced cancer and pain. We confirmed the previously reported 4-factor solution in older (≥ 60 years) and younger (<60 years) patients. Internal consistency reliability and convergent validity were similar across age groups, although the SF-MPQ-2 sensory subscales were correlated with mental health quality of life in older, but not younger, patients. Older and younger patients selected the same words with the same intensity to describe their pain. The most commonly selected words in both age groups were aching, tiring-exhausting, sharp, and dull. These results demonstrate that the SF-MPQ-2 is appropriate for use across the adult lifespan in people with cancer pain.PerspectiveThis study demonstrated that the SF-MPQ-2 is valid for use in older and younger people with advanced cancer and pain. This measure could improve cancer pain assessment across the adult lifespan, which may lead to improved pain management.Copyright © 2014 American Pain Society. Published by Elsevier Inc.
