Development and Validation of the HL6: a Brief, Technology-Based Remote Measure of Health Literacy.

Background: Most health literacy measures require in-person administration or rely upon self-report.

Objective: We sought to develop and test the feasibility of a brief, objective health literacy measure that could be deployed via text messaging or online survey.

Design: Participants were recruited from ongoing NIH studies to complete a phone interview and online survey to test candidate items.

Factors associated with COVID-19 vaccine trust and hesitancy among adults with chronic conditions.

In a survey of older adults at higher risk for COVID-19 complications, we sought to describe expectations of trust in the safety and efficacy of a future COVID-19 vaccine, and level of hesitancy about receiving it. We also assessed whether these expectations were associated with known or suspected contributors to vaccine hesitancy, disparities in vaccine receipt, and potential targets for public health outreach. From May 1-22, 2020, we performed telephone surveys of 601 older adults with chronic conditions in metro Chicago about their COVID-19 experiences and levels of vaccine trust and hesitancy.
