  have had higher scores on pain-related
  disability

• The Battery for Health Improvement (BHI)
 It is a self-report inventory to identify

• Pain Patient Profile (P-3)
  Effective instrument for briefly
  assessing for personality and psychological
  characteristics that are known to affect
  pain perception and treatment response of
  patients in pain
