Abstract
Psychosocial factors are strongly related to the onset of chronic pain, so chronicity of pain should be prevented from an early stage. However, simple methods for evaluating such psychiatric problems are limited. The Brief Scale for Psychiatiric Problems in Orthopaedic Patients (BS-POP), a simple questionnaire enabling evaluation of psychiatric problems in orthopaedic patients, was recently developed at our university. The reliability, factorial validity, criterion validity, and reproducibility of the BS-POP were studied. Orthopaedic surgeons should consider patients' psychiatric problems before operating. We should consider not only psychiatric problems but also brain dysfunctions that could be related to chronic pain.
