Development and validation of an instrument to assess oral health literacy in Norwegian adult dental patients
Results: The Cronbach’s alpha values of AHLID were 0.98 for internal consistency reliability (p<0.01) and 0.81 for test-retest reliability (p<0.05). AHLID score 3 was most frequent while very few fulfilled the criteria for score 1 and 5. Linear multiple regression analysis showed that lactobacillus in saliva and knowledge of risk factors for periodontitis and caries were predictor variables of AHLID score.
Conclusions: AHLID appears to be reliable and valid to assess oral health literacy in Norwegian adults, and suggests a method for country-specific health literacy instruments.
