FIP September Evaluation of the REALM Health Literacy Test in a Developing Country Ros Dowse Lebo Lecoko Tina Ehlers
FIP September Introduction Health care systems require that patients be able to read Low-literate patients have the highest morbidity and mortality rates from chronic diseases and conditions
FIP September Definition of health literacy “…the capacity of an individual to obtain, process and understand basic health information and services needed to make appropriate health decisions”
FIP September South Africa Verbal information……… PROBLEM! Written information……… PROBLEM! Widespread limited literacy skills Literacy statistics: illiterate45% semi-literate 25% literate 30% 3 out of 4 patients – problems with reading
FIP September Measurement of health literacy Indirect measurement - standard of education Direct measurement - literacy test or task Valuable information - provide appropriately tailored medicine information
FIP September REALM Test Health literacy test developed in USA Available in English Takes 1 – 3 mins to administer Estimates reading level below grade 9 Consists of 3 lists of 22 words each, arranged in order of increasing difficulty Words read aloud and pronunciation checked Grades estimated according to number of words pronounced correctly
FIP September Objective To evaluate the applicability of the REALM test in a South African English second-language population
FIP September Methodology 125 Xhosa respondents of different educational levels were tested with the aid of interpreters All stated that they could read and understand English Demographic data obtained Respondents asked to read aloud as many words as possible from the 3 lists and then to explain their meaning
FIP September Criteria for success or failure Cases 1 and 2 to account for > 80% respondents Apply this to > 2/3 (44 of 66) words CaseReadUnderstand Succeeds / Fails 1 Succeeds 2XX 3 X Fails 4X Fails

FIP September Words which were poorly understood: Haemorrhoids0.0% Colitis0.0% Osteoporosis0.8% Hepatitis0.8% Inflammatory1.6% Seizure1.6% Anemia2.4% Menopause4.0%
FIP September REALM Test Accept / Reject? REALM test only “worked” for 8 of the 66 words It “failed” in 41% of a total of 8250 cases (125 respondents x 66 words)
FIP September Conclusion REALM test is not a suitable tool to assess health literacy in this population Ability to pronounce words gives no indication of comprehension Schooling is an unreliable literacy marker Enables suitable terms to be identified for inclusion in patient information leaflets
