This study was designed to assess the reliability and validity of a
Pain Behavior Observation method with fibromyalgia syndrome
(FS) subjects and to determine the factors which predict pain
behavior among FS subjects. Fifty-eight female FS subjects
participated in the videotaped Pain Behavior Observation
method. Subjects also completed the McGill Pain Questionnaire
(MPQ), the Arthritis Impact Measurement Scale (AIMS), and the
Symptoms Checklist-90-Revised (SCL-90-R). Pain behavior totals
were derived using the Pain Behavior Observation method of
McDaniel et al. (1986). Results indicated that the scoring
method of Keefe and Block (1982) developed for use with back
pain patients was more generalizable to this FS sample. Total
pain behavior score using the Keefe and Block scoring method
was correlated with self-report pain. Interrater reliability
ranged from 0.9 to 0.99. Hierarchical multiple regression
analyses revealed that age and physical disability predicted
the total pain behaviors.
The Pain Behavior Observation method appears a valid pain
measurement technique independent of depression among FS
patients. Directions for future research are discussed.
