Health Literacy Overview

1. Health Literacy Overview Rima E Rudd, MSPH, ScD Health Literacy Studies Harvard University School of Public Health National Center for the Study of Adult Learning and Literacy

2. Functional Literacy NALS NAALS IALS

3. Functional Literacy Ability to read, write and speak in English, and computeand solve problems at levels of proficiency necessary to function on the job and in society, to achieve one’s goals, and develop one’s knowledge and potential. The National Literacy Act of 1991

4. NALS: National Adult Literacy Survey 1992 1. Prose Literacy:process information presented in full sentences/ paragraphs. 2. Document Literacy: process information presented in forms, tables, maps, schedules, charts… 3. Quantitative Literacy:apply numerical operations.

5. 2002: National Assessment of Adult Literacy Survey National Assessment of Adult Literacy Survey, 2002: Assessment items will include materials used for health related tasks.

6. Functional Literacy Assessments 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.

7. Progression:Learning to Read Reading to Learn Readers at Grade 1-3 level are learning to: • decode letter groups • recognize and sound out words • derive meaning from words • link words in sentences • derive meaning from sentences.

8. Prose Literacy 49% of Adults May Have Some Difficulty: • Finding one piece of information in a sports article; • Finding 2 pieces of information in a news article. They Generally Cannot: • Interpret instructions • Infer theme from a poem • Describe contrasting views in an editorial.

9. Document Literacy 51% of Adults May Have Some Difficulty: • Completing a job application; • Interpreting a payroll forms. They Generally Cannot: • Read tables and graphs • Locate intersection on street map • Use a bus or train schedule.

10. Quantitative Literacy 47% of Adults May Have Some Difficulty: • Balancing a checkbook; • Figuring a tip. They Generally Cannot: • Complete an order form • Determine the amount of interest from a loan advertisement.

11. Literacy as a Tool Reading to Do: Health Context

12. Basic Health Literacy • Read and comprehend health information and directions. • Complete medical history, informed consent, and insurance forms. • Apply literacy skills to: • prescriptions • appointment cards • medicine labels • directions for care.

15. Get lost Make errors Run out of words Retreat into silence Cover up or Lie Limit participation Assume a passive role Be assigned a passive role Lose entitlements Lose rights When Words Get in the Way

16. Research to Date Trends Scope Findings

17. 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) D'Alessandro et al, The Readability of Pediatric Patient Education Materials on the World Wide Web 2001.

24. Agenda Research & Practice

25. Unexplored Areas How well are people with limited literacy skills managing: • Health Promotion and Protection • Early Detection and Screening • Broader health services such as Mental Health, Oral Health • Interactions with social services and entitlement programs • Community, work and social action for policy change ?

26. Unexplored Areas How well are people with limited literacy skills managing health related decisions: • At Home, Work, Schools, Community • In medical, dental, and other health service settings • In the Policy Arena ?

27. New Territories for Research • Links between literacy and • verbal skills • Links between literacy and • oral comprehension • Links between literacy and • background knowledge

28. New Territories for Research • Causal pathways of how poor health literacy influences health • Outcomes & costs associated with poor health literacy • Effective health education techniques • Evaluation of plain language directives and use of non-print media
