Cognitions and beliefs appear important in predicting adjustment to chronic
pain. The current study examines how cognitions and beliefs are related to
psychosocial functioning. One hundred and sixty-three chronic pain out-pat
ients were assessed. Regression analyses were performed using scores on the
Pain Beliefs and Perceptions Inventory and the Inventory of Negative Thoug
hts in Response to Pain as predictor variables and responses to the West Ha
ven Yale Multidimensional Pain Inventory as criterion variables. Pain cogni
tions and pain beliefs were correlated. After controlling for demographics,
employment status and pain severity, pain beliefs and cognitions accounted
for a significant amount of the variance in general activity, pain interfe
rence, and affective distress. Negative cognitions, particularly negative s
elf-statements, were more predictive of outcome than pain beliefs. Although
these data are correlational, they provide additional support for a biopsy
chosocial model of adjustment to chronic pain. (C) 2000 International Assoc
