Validation of a Facial Image Scale to assess child dental anxiety

Summary. Objective. To examine the validity of a scale that uses faces as an indicator of children’s dental anxiety. Setting. Department of Child Dental Health waiting room, Newcastle Dental Hospital. Subjects and methods. 100 children (aged 3–18 years) completed the Facial Image Scale (FIS) and the Venham Picture Test (VPT) in the dental hospital waiting room. Results. A strong correlation (0·7) was found between the two scales, indicating good validity for the FIS. Findings also showed that a small, but significant, number of children are anxious in the dental context. Conclusion. The findings suggest that the FIS is a valid means of assessing child dental anxiety status in a clinical context.
