title: Altering beliefs about pain and impairment in a functionally oriented treatment program for chronic low back pain.
abstract: OBJECTIVE
  This study examined pain and impairment beliefs [measured with the Pain and Impairment Relationship Scale, (PAIRS)] of chronic low back pain patients during rehabilitation and hypothesized that pain beliefs would be stronger in drop-out subjects, decrease during treatment, and after treatment correlate strongly with disability measures.
  
  
  METHODS
  Prospective cohort.
  
  
  METHODS
  Outpatient, functionally oriented rehabilitation program for chronic low back pain.
  
  
  METHODS
  72 consecutive chronic low back pain referral patients disabled from working because of pain. INVOLVEMENT: Interdisciplinary rehabilitation with a focus on intensive physical reconditioning was employed.
  
  
  METHODS
  Program completion versus drop-out groups and pretreatment and posttreatment pain, disability, depression, and PAIRS scores were compared.
  
  
  RESULTS
  Thirty patients dropped out and 42 subjects completed treatment. The PAIRS scores at evaluation were similar for both groups. The PAIRS scores improved significantly during treatment (p < 0.001). Posttreatment PAIRS scores correlated highly with disability measures (r = 0.79, p < 0.001).
  
  
  CONCLUSIONS
  Pain beliefs are of minimal value for predicting treatment compliance, but may be altered during functionally oriented treatment of chronic low back pain. Posttreatment disability closely mirrored attitudes and belief-associated pain and impairment.
