Evaluation of instruments to assess health literacy in Arabic language among Iraqis

BackgroundLow health literacy is associated with lack of medical information, less use of preventive measures, low medication adherence rates, high health care costs and high risk of hospitalization.ObjectiveThe aims were to compare the results of the three health literacy tests, to measure for the first time the health literacy level of Iraqis, to describe the use of standardized health literacy tests, to evaluate reliability and validity of the Arabic versions of these tests, and to investigate whether there is relationship between the participant characteristics and the health literacy level.MethodsA convenience sample of 95 subjects was studied in five community pharmacies in Al-Najaf and Babylon governorates, Iraq. Three health literacy tests, the Single Item Literacy Screener (SILS), the New Vital Sign (NVS) and the Short version of the Test of Functional Health Literacy in Adults (S-TOFHLA), were translated in the Arabic language and administered to the pharmacy customers.ResultsThere were no statistically significant associations between age, gender, education and current education status and NVS score, but there were significant positive associations between the level of education and each one of SILS, New SILS, and S-TOFHLA scores.ConclusionsSILS has one subjective, possibly culturally biased question. Since Iraqis are generally not exposed to reading product labels, the NVS test might be not an accurate measure for them. S-TOFHLA was the most comprehensive test and gave equitable results. The Arabic version of S-TOFHLA can be used to measure health literacy in 22 Arabic speaking countries.
