A cross-cultural cross validation of the Dental Fear Survey in South East Asia.

This study was designed as a cross-cultural replication and cross validation of the Dental Fear Survey (DFS) in two groups of Singapore adults: university students and military conscripts. Factor analysis of the DFS in each of these dissimilar samples revealed factor structures that were highly comparable to one another as well as to those obtained in the U.S.A. Behavioral and physiological fear assessment during exposure to simulated dental treatment also showed results comparable to those found in Western cultures. Self report measures were more likely to correlate with other self reports than with physiologic or behavioral measures. Among university students, those who had visited a dentist within the past year had significantly lower DFS scores than those who had avoided dentistry. The fear-avoidance relationship did not hold for military subjects who reported less dental fear overall. It was concluded that the DFS was factorially stable; and therefore, generalizable to this South East Asia culture.
