development and validation of the computer administered health literacy assessment
like you just
literacy is increasingly been recognized as important but how do you measure
the old way was to give an individually administered paper pencil measure that time discourse
interpret
the new ways by automated administration scoring using simulations of actual health care situation
i
and that duration
professor and chair of the department of psychiatry the improvement is no was not strictly
verse that
i'll of the team we developed a new measure of literacy that is computer administered
and score
this available in both english and spanish
the english arm of the project is fostering literacy for good health today or fly
and the spanish arm is needed this sorry on the on the slu
or the s
here is are typical computer setup
this is a standard off the shelf touch screen computer that you can purchase the
many large electronics stores
is also illustrates a typical question
the text of the talkers heard by the person being tested over the computer speakers
in this case
he or she must use information from the table of the right answer the question
five possible answers or it'll at the person in two cases are answers by tapping
on one of them and then hitting the submit button
the computer automatically advances to the next question
the computer allows us to use a variety of stimuli and questions including graphics and
videos
but the number of questions are very straightforward
there is a question that assesses a single factor how levels of cholesterol are tested
on the other hand here is a question based on the actual us national weather
service graph used for calculating wind chill risk
if it appears difficult it is
this is one of the harder questions that we included to be sure that we
assess a wide range of difficulties
the major includes several groups of questions based on videos
this one is the simulation of a researcher explaining a clinical study to a possible
participant
the person watches the video then answers a series of questions about it
another video presents a simulated tv report on how to understand health information on the
internet
other questions assessed someone's understanding of their quality information on a website
ability to navigate a hospital using a man
and make an informed choice between two over the counter medications
our paper describes how we develop the items and evaluated them to make sure they
work in spanish and english this figure one in the paper explains the steps
in order to be sure that the new major evaluated a wide range of content
we develop times based on the content here is from the two thousand four institute
of madison report using the literacy formats prose document quantitative developed by the educational testing
service
table one of the paper gives examples
the paper also explains results of the study so far
using exploratory in confirmatory factor analysis we identified sub scales of the overall measure including
general health literacy numeracy listening in conceptual knowledge
we use nonparametric item response three analysis to assess whether items work in both spanish
and english
our analyses show that the new measure is closely related other test of literacy such
as a test functional help literacy an adult or talk
table four in the paper shows the correlations of the new measure with other assessments
of literacy
the project is nearly finished and we plan to make fly you just available soon
you can learn more about the flight you just project are our website w dot
