Resumo
Background: The Dental Discomfort Questionnaire (DDQ) is an observational instrument intended to measure dental
discomfort and/or pain in children under 5 years of age. This study aimed to validate a previously cross-culturally
adapted version of DDQ in a Brazilian children sample.
Methods: Participants included 263 children (58.6% boys, mean age 43.5 months) that underwent a dental examination
to assess dental caries, and their parent that filled out the cross-culturally adapted DDQ on their behalf. Exploratory factor
analysis (principal component analysis form) and psychometric tests were done to assess instrument’s dimensionality
and reliability.
Results: Exploratory factor analysis revealed a multidimensional instrument with 3 domains: ‘eating and sleeping
problems’ (Cronbach’s alpha 0.81), ‘earache problems’ (alpha 0.75), and ‘problems with brushing teeth’ (alpha 0.78). The
assessment had excellent stability (weighted-kappa varying from 0.68 to 0.97). Based on the factor analysis, the model
with all 7 items included only in the first domain (named DDQ-B) was further explored. The items and total median
score of the DDQ-B were related to parent-reported toothache and the number of decayed teeth, demonstrating good
construct and discriminant validities.
Conclusions: DDQ-B was proven a reliable pain assessment tool to screen this group of Brazilian children for
caries-related toothache, with good psychometric properties.
