On the structure of childhood dental fear, using the Dental Subscale of the Children's Fear Survey Schedule.

The aim of the present study was to assess the structure of childhood dental fear, using the Dutch parent's version of the Dental Subscale of the Children's Fear Survey Schedule (CFSS-DS) and to report on its validity. MATERIALS AND METHODS: Factor analysis (principal components, varimax rotation) was performed using the scores of a group of high fearful children (n=322). Results were compared with those from a previous study among low fearful children, also using the parent's version of the CFSS-DS. In addition, mean item scores between the samples were compared to examine specific differences. RESULTS: Factor analysis resulted in a stronger factor pattern than that found in previous research. Four factors accounting for 60% of the variance were found: 1) fear of general, less invasive aspects of dental treatment; 2) fear of medical aspects; 3) fear of drilling; 4) fear of strangers. CONCLUSION: It was concluded that with increasing fear levels, underlying factors of dental fear can be distinguished more clearly. The CFSS-DS was indicated to be a reliable and valid measure of dental fear.
