  • 1992 National Adult Literacy Survey (NALS) no
    focus on health tasks

  • Household survey of approximately 20,000
  • Data on background characteristics, performance
    of everyday literacy tasks and skills underlying
    performance

13
General skills assessed by health literacy tasks
  • Word-level reading skills Decoding and
    recognizing words
  • Language comprehension skills Understanding the
    structure and meaning of sentences
  • Text search skills Searching text efficiently
  • Inferential skills Drawing appropriate
    text-based inferences
  • Computation identification skills Identifying
    the calculations required to solve quantitative
    problems
  • Computation performance skills Performing any
    required calculations
  • Application skills Using newly searched,
    inferred, or computed information to accomplish a
    variety of goals
  • Slides on HLC from S. White, August 2004

NAAL Health Literacy Component
  • Objective data based on respondents performance
    on health-related tasks from everyday life
  • Measures ability to understand and use
    health-related print information
  • Aspects NOT covered
  • Oral communication
  • Knowledge
  • Jargon and technical terms

Bringing to bear general literacy skills on
health tasks
  • The health literacy score measures the ability to
    apply general literacy skills to perform a
    variety of health-related tasks
  • For example, one must
  • Search text effectively and efficiently (a
    general literacy skill) to complete a patient
    information form (a health-related task)
  • Draw appropriate inferences (a general literacy
    skill) to follow health screening recommendations
    (a health-related task)
  • Perform appropriate computations (a literacy
    skill) to avoid under- or over-dosing (a
    health-related task)

16
Uses of health literacy data
  • HLC data can assist in
  • Identifying the health literacy skills of target
    audiences
  • Guiding the development of health information
    tailored to the literacy strengths and weaknesses
    of target audiences so that the written material
    is less likely to exceed the literacy skills of
    target audiences
  • Providing input for development of programs to
    improve health literacy skills

17
Goal increased health literacy in the service of
better decisions and health
  • Credible, understandable and applicable
    information for all
  • Systems that help and support rather than hinder,
    frustrate or embarrass
  • Providers who are informed about what they need
    to communicate to all patients and clients
  • Providers who communicate clearly and
    appropriately with all patients and clients
