Poorly controlled cancer pain is a significant public health problem throughout the world. There are many barriers that lead to undertreatment of cancer pain. One important barrier is inadequate measurement and assessment of pain. To address this problem, the Pain Research Group of the WHO Collaborating Centre for Symptom Evaluation in Cancer Care has(More)
UNLABELLED A consensus meeting was convened by the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) to provide recommendations for interpreting clinical importance of treatment outcomes in clinical trials of the efficacy and effectiveness of chronic pain treatments. A group of 40 participants from universities,(More)
BACKGROUND Fatigue is a major disease and treatment burden for cancer patients. Several scales have been created to measure fatigue, but many are long and difficult for very ill patients to complete, or they are not easy to translate for non-English speaking patients. The Brief Fatigue Inventory was developed for the rapid assessment of fatigue severity for(More)
BACKGROUND AND METHODS Pain is often inadequately treated in patients with cancer. A total of 1308 outpatients with metastatic cancer from 54 treatment locations affiliated with the Eastern Cooperative Oncology Group rated the severity of their pain during the preceding week, as well as the degree of pain-related functional impairment and the degree of(More)
As a way of delineating different levels of cancer pain severity, we explored the relationship between numerical ratings of pain severity and ratings of pain's interference with such functions as activity, mood, and sleep. Interference measures were used as critical variable to grade pain severity. We explored the possibility that pain severity could be(More)
OBJECTIVES The Brief Pain Inventory (BPI) is a short, self-administered questionnaire that was developed for use in cancer patients. While most empirical research with the BPI has been in pain of that etiology, the questionnaire is increasingly evident in published studies of patients with non-cancer pain. The current research addresses the need for formal(More)
We describe the development of a Chinese version of the Brief Pain Inventory (BPI-C) and demonstrate its reliability and validity. We also report the use of the BPI-C in a three hospital study of cancer pain and its treatment. As with other language versions of the BPI, factor analysis of the BPI-C items results in a two factor solution that satisfies the(More)
This paper reports the development of a self-report instrument designed to assess pain in cancer and other diseases. It is argued that issues of reliability and validity should be considered for every pain questionnaire. Most research on measures of pain examine reliability to the relative neglect of validity concerns. The Wisconsin Brief Pain Questionnaire(More)
PURPOSE To prospectively evaluate the effectiveness, safety, and clinical benefits of once-weekly epoetin alfa therapy as an adjunct to chemotherapy in anemic cancer patients. PATIENTS AND METHODS A total of 3,012 patients with nonmyeloid malignancies who received chemotherapy were enrolled onto this multicenter, open-label, nonrandomized study conducted(More)
OBJECTIVE To provide recommendations for the core outcome domains that should be considered by investigators conducting clinical trials of the efficacy and effectiveness of treatments for chronic pain. Development of a core set of outcome domains would facilitate comparison and pooling of data, encourage more complete reporting of outcomes, simplify the(More)
