OBJECTIVE: To develop and validate an interview instrument to assess oral health literacy in Norwegian adult dental patients. MATERIALS AND METHODS: The instrument, Adult Health Literacy Instrument for Dentistry (AHLID), was based on an OECD instrument used to assess general literacy in adults. One hundred and thirty Norwegian adults (mean age = 48 years; 57% women) participated. AHLID included a selection of oral health-related printed texts that ranged from 1-5 with respect to difficulty. A questionnaire regarding socio-demographic variables and knowledge of risk factors for oral disease was used. DMFT, stimulated salivary flow rate and streptococcus mutans and lactobacillus in saliva was also examined. RESULTS: The Cronbach's alpha values of AHLID were 0.98 for internal consistency reliability (p < 0.01) and 0.81 for test-re-test 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.
