0:00:00development and validation of the computer administered health literacy assessment
0:00:04like you just
0:00:06literacy is increasingly been recognized as important but how do you measure
0:00:11the old way was to give an individually administered paper pencil measure that time discourse
0:00:17interpret
0:00:18the new ways by automated administration scoring using simulations of actual health care situation
0:00:26i
0:00:27and that duration
0:00:28professor and chair of the department of psychiatry the improvement is no was not strictly
0:00:34verse that
0:00:35i'll of the team we developed a new measure of literacy that is computer administered
0:00:39and score
0:00:41this available in both english and spanish
0:00:44the english arm of the project is fostering literacy for good health today or fly
0:00:49and the spanish arm is needed this sorry on the on the slu
0:00:53or the s
0:00:55here is are typical computer setup
0:00:57this is a standard off the shelf touch screen computer that you can purchase the
0:01:01many large electronics stores
0:01:03is also illustrates a typical question
0:01:06the text of the talkers heard by the person being tested over the computer speakers
0:01:11in this case
0:01:12he or she must use information from the table of the right answer the question
0:01:17five possible answers or it'll at the person in two cases are answers by tapping
0:01:22on one of them and then hitting the submit button
0:01:26the computer automatically advances to the next question
0:01:31the computer allows us to use a variety of stimuli and questions including graphics and
0:01:35videos
0:01:36but the number of questions are very straightforward
0:01:39there is a question that assesses a single factor how levels of cholesterol are tested
0:01:44on the other hand here is a question based on the actual us national weather
0:01:48service graph used for calculating wind chill risk
0:01:51if it appears difficult it is
0:01:54this is one of the harder questions that we included to be sure that we
0:01:58assess a wide range of difficulties
0:02:00the major includes several groups of questions based on videos
0:02:05this one is the simulation of a researcher explaining a clinical study to a possible
0:02:09participant
0:02:10the person watches the video then answers a series of questions about it
0:02:15another video presents a simulated tv report on how to understand health information on the
0:02:19internet
0:02:21other questions assessed someone's understanding of their quality information on a website
0:02:25ability to navigate a hospital using a man
0:02:29and make an informed choice between two over the counter medications
0:02:35our paper describes how we develop the items and evaluated them to make sure they
0:02:39work in spanish and english this figure one in the paper explains the steps
0:02:45in order to be sure that the new major evaluated a wide range of content
0:02:49we develop times based on the content here is from the two thousand four institute
0:02:53of madison report using the literacy formats prose document quantitative developed by the educational testing
0:03:01service
0:03:02table one of the paper gives examples
0:03:06the paper also explains results of the study so far
0:03:10using exploratory in confirmatory factor analysis we identified sub scales of the overall measure including
0:03:16general health literacy numeracy listening in conceptual knowledge
0:03:22we use nonparametric item response three analysis to assess whether items work in both spanish
0:03:29and english
0:03:30our analyses show that the new measure is closely related other test of literacy such
0:03:35as a test functional help literacy an adult or talk
0:03:39table four in the paper shows the correlations of the new measure with other assessments
0:03:44of literacy
0:03:46the project is nearly finished and we plan to make fly you just available soon
