The reluctance to generalize corrective experiences in chronic low back pain patients: a questionnaire study of dysfunctional cognitions

The present study investigated whether pain catastrophizing and pain-related fear is related to a reluctance to generalize an experience of lesser pain than expected to other similar situations. Eighty-five patients with chronic low back pain (40 males; 45 females; age range =21-63 years) completed a series of vignettes assessing catastrophizing, overgeneralization, personalization and selective abstraction related to general life experiences and to low back pain (LBP) experiences. Three vignettes also assessed the lack of generalization of corrective experiences related to LBP. Our results showed that dysfunctional cognitions related to general life experiences were the strongest predictor of the self-denigration subscale of the Beck Depression Inventory (13131), whereas only dysfunctional cognitions related to LBP had a unique contribution in the prediction of the somatic and physical function subscale of the BDI. Furthermore, dysfunctional cognitions related to LBP were significantly correlated with interference with daily life due to pain. As predicted, pain catastrophizing and pain-related fear had a unique contribution in predicting the lack of generalization of corrective experiences, over and above sociodemogaphic variables, pain severity and pain duration.
