The pain behavior check list (PBCL): psychometric properties in a college sample

The Pain Behavior Check List (PBCL) was designed to assess the frequency of four dimensions of pain behavior: distorted ambulation, affective distress, facial/audible expressions, and seeking help. This study evaluated theoretical factor structure, internal consistency, and construct validity of the PBCL in a nonclinical college sample. Results provided support for the four-factor oblique model, compared to the one-factor and the four-factor orthogonal models. The PBCL total and subscales showed satisfactory internal consistency. Support for convergent validity was demonstrated by high correlations between the PBCL and several measures of pain behavior and with other pain indices. In addition, results of the confirmatory factor analyses suggested that self-report measures of pain can be differentiated from self-report measures of anxiety and depression.
