Findings grouped by 5 skill levels for each literacy area.

• Level 1 is the lowest skills level.• People at Level 1 have reading

skills of grade 1-3 level.

Review of the Literature: Trends

Number of Citations•1970s - ~ 11 •1980s - ~ 37 •1990s - ~ 240 •Each Year within Current Decade:

•2000 - ~ 24 •2001 - ~ 16 [through Sept]

18

Review of the Literature: Scope

•Materials Assessment•Comprehension of written materials•Match between patients’ abilities

and reading materials•Use of services •Knowledge level•Outcomes

19

Research Findings: Materials and Comprehension•Materials written at inappropriate reading grade levels.•Mismatch between reading levels of materials & reading ability of intended audience.

20

Research Findings: Health Impact

• Poorer overall health• Less likely to make use of screening• Present in later stages of disease• More likely to be hospitalized• Poorer understanding of treatment• Lower adherence to medical

regimens

21

Research Finding: Shame• Almost 40% of patients with low

functional literacy admitted feelings of shame:– 67% had never told their spouses – 53% had never told their children

22

Review: Materials on the Internet

Digital Divide:• Of the 1,000 sites reviewed, only 10 were appropriate for limited-literacy adults.•Generalized information on topics of interest is available but not at literacy levels that underserved Americans need.

Lazarus and Mora, The Children’s Partnership, 2000

23

Review: Materials on the Internet

Review of 89 pediatric patient information web sites: information is not written at appropriate reading levels for the average adult (8th grade or lower)
