The Pain Beliefs and Perceptions Inventory: a British replication.

The factorial structure, reliability, and validity of the Pain Beliefs and Perceptions Inventory (PBPI) was investigated in a sample of 84 pain patients drawn from a pain clinic in the United Kingdom. The recovered factorial structure replicated that of a previous study. The 4 derived subscales, Mysteriousness, Self-Blame, Pain Constancy and Pain Permanence, had excellent reliability (internal consistency); Chronbach's alpha was greater than 0.80. However, the construct validity of the PBPI, assessed by examining the association between the subscales and the Coping Strategies Questionnaire (CSQ), was not supported. The results are discussed with particular reference to the interpretative issues concerning 2 of the subscales and their relation to the concept of the 'time line' component of illness representation.
