Factor analysis of the Dental Fear Survey disclosed three stable and reliable factors. The first factor related to patterns of dental avoidance and anticipatory anxiety. The second factor related to fear associated with specific dental stimuli and procedures. Factor three concerned felt physiologic arousal during dental treatment. Cross validation showed these three factors to be consistent across four demographically and geographically diverse groups.
