About the Validation of this Measure
Country where validated:
United States of America
Content validity:
Expert panel included in development process. Uses real world stimuli as part of items. Development included user pre-testing.
Criterion validity:
As hypothesized, the HLSI was moderated correlated with the S-TOFHLA (r=0.36). Correlations between the health literacy domains in the HLSI and the S-TOFHLA were highest for the print-prose, print-document, and print-quantitative skill area and much lower for the Internet and oral literacy domains as expected.
Reliability (Cronbach Alpha):
0.86
