title: Pain language of bone marrow transplantation patients.
abstract: Previous studies have shown that hypnosis may be effective in reducing intensity of pain among bone marrow transplantation patients whereas cognitive behavioral intervention without imagery was not effective for this group of patients. Since hypnosis alters patients' perception of pain and cognitive behavioral intervention changes patients' beliefs and improves their coping with pain, we hypothesized that sensory pain is more important than affective pain in understanding the pain experience of patients undergoing bone marrow transplantation. To test this hypothesis we administered the McGill Pain Questionnaire longitudinally to 50 consecutive eligible recipients of bone marrow transplantation during hospitalization to assess the different dimensions of pain they experienced. Consistent with our hypothesis, sensory pain fluctuated with treatment stages, and the pattern was consistent with previous findings. Patients reported significantly higher sensory pain than affective pain at all assessment points. In contrast, affective pain remained low and stable throughout the treatment. Our results contribute to the understanding of the nature of pain in bone marrow transplantation and suggest pain management strategies that focus on sensory pain as in hypnosis are more useful for such patients.
