Objective:
Dental fear screening is an important part of providing a positive pediatric dental experience. To improve efficiency, the development of a single-item dental fear assessment tool for children has been desired. In this psychometric analysis, the reliability and validity of the Dental Anxiety Question (DAQ) is studied when used in children aged 7 to 18 years.
Methods:
Participants completed the DAQ (pre-tx-DAQ), the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS), and a demographic information questionnaire before treatment. Participants repeated the DAQ after treatment (post-tx-DAQ) and once more at least 2 weeks later (follow-up-DAQ). Stability reliability within the DAQ scores and criterion validity with the CFSS-DS were evaluated.
Results:
Stability reliability analyses between pre-tx-DAQ/post-tx-DAQ and post-tx-DAQ/follow-up-DAQ demonstrated significant positive correlations: Spearman rank correlation coefficient (rs) = 0.420, rs2 = 0.18, P < .001, and rs = 0.563, rs2 = 0.32, P < .001, respectively. Criterion validity analysis between the pre-tx-DAQ and CFSS-DS also demonstrated a significant correlation: Pearson correlation coefficient (r) = 0.584, r2 = 0.34, P < .001.
Conclusion:
The stability reliability and criterion validity of the DAQ was proved among children.
