IS PAIN SENSITIVITY ASSOCIATED WITH DENTAL AVOIDANCE

The present investigation examined whether pain sensitivity is associated with dental avoidance. Whereas the aim of the first study was to determine whether pain sensitivity can be distinguished from dental fears and health concerns, the aim of the second study was to examine the structure of cognitive aspects of pain sensitivity, and the aim of the third study was to examine the relationships of pain sensitivity to anxiety sensitivity, fear, pain, and avoidance. In the first study (n = 222), a factor analysis performed with items from the Dental Phobia and Pain Sensitivity Inventory distinguished a pain sensitivity factor from factors relating to dental phobia and health concerns. The factor structure of the Pain Sensitivity Index was examined in the second study (n = 181), and similarly, a pain sensitivity factor was interpreted in the data. The third study (n = 65) found that although pain sensitivity correlated significantly with anxiety sensitivity, these constructs are not identical to each other. For instance, pain sensitivity but not anxiety sensitivity correlated significantly with blood-injury phobia. Pain sensitivity should be taken into account in future studies of dental phobia as pain sensitivity was found to be predictive of pain intensity, and pain intensity was found to be predictive of dental avoidance. © 1991.
