%X OBJECTIVE: The goal of this study was to assess the validity of the Romanian version of the Index of Dental Anxiety and Fear (IDAF-4C+) questionnaire.
METHODS: This study was conducted on a convenience sample of past patients and their acquaintances through an online questionnaire administered on the Google Forms platform between May 2021 and September 2022. The sections of the survey were demographic characteristics, the dental anxiety scale questionnaire, the IDAF-4C+ questionnaire, a single question about dental fear, and previous dental treatments.
RESULTS: In total, 239 participants were included in the study, and the mean age was 37. The IDAF-4C questionnaire had good internal validity (Cronbach alpha was 0.945). The IDAF-4C had good convergent validity, and it was positively correlated with the dental anxiety scale (r = 0.825, p < 0.001) and the question about the fear of going to the dentist (r = 0.738, p < 0.001). The questionnaire had good reliability, and the intraclass correlation was 0.985. Lower levels of dental anxiety were associated with scaling, orthodontic treatment, and dental implants. A confirmatory factor analysis was conducted after the removal of the first question from the phobia module, and residual covariance was added between items four and nine of the stimulus module, showing a good fit for the retained questions of the IDAF-4C+, grouped by module.
CONCLUSIONS: The Romanian version of the IDAF-4C+ showed acceptable psychometric properties.
