The factorial structure, reliability, and validity of the Pain Beliefs
and Perceptions Inventory (PBPI) was investigated in a sample of 84 p
ain patients drawn from a pain clinic in the United Kingdom. The recov
ered factorial structure replicated that of a previous study. The 4 de
rived subscales, Mysteriousness, Self-Blame, Pain Constancy and Pain P
ermanence, 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 res
ults are discussed with particular reference to the interpretative iss
ues concerning 2 of the subscales and their relation to the concept of
the 'time line' component of illness representation.
