Description
Instrument to measure a person’s ability to understand dental terms and oral health information. Contains both reading comprehension and numeracy sections to measure a person’s ability to perform oral health literacy tasks that require reading comprehension and numeracy skills.

About the Validation of this Measure
Country where validated:
Malaysia
Content validity:
Process of translation, adaptation, and review. Translation - two translators, a dental public health specialist and native language speaker .Both translators were proficient in English and their native language was Malay. Next, the two forward translations were reviewed by a review committee, comprising of two dental public health lecturers and two dental public health doctorate students. All members were fluent in both English and Malay languages.
Criterion validity:
In addition to the OHLI-M, the reading comprehension of health literacy was measured by the Malay version of the Short Test of Functional Health Literacy in Adults (S-TOFHLA-M).The correlation between the reading comprehension section of OHLI-M scores and S-TOFHLA-M scores was examined by Spearman’s rank correlation because the variables were not normally distributed. The correlation was positive (Spearman’s rho = 0.37, p < 0.001), in support of convergent validity between the OHLI-M and S-TOFHLA-M. No significant correlation between the OHLI-M scores and DMFT index or CPI scores (Table 4), which showed lack of support for concurrent validity. the numeracy scores of the OHLI-M were not compared to that of the TOHFLA. This was because the S-TOFHLA-M that was utilized in this study lacked the numeracy section.
Reliability (Cronbach Alpha):
0.88
Reliability notes:
The OHLI-M showed good reliability among adults in Malaysia
