Parental functional health literacy relates to skip pattern questionnaire error and to child oral health.

The study's purpose was to determine if parental dental functional health literacy related to child oral health. A secondary aim was to assess if errors in completing the questionnaire related to FHL and child oral health. Parents of pediatric clinic children (N = 101) completed questionnaires and dental caries indices were recorded. Higher FHL was negatively correlated with worse child caries (r = -0.23), but not subjective oral health. Mean FHL seemed to differ by skip pattern (p = 0.087), indicating it may be a potential FHL proxy.
