Reducing Assessment Barriers for Patients With Low Literacy

Status Completed

Clinical Trial Summary

The purpose of this study is to determine the effects of health literacy on questionnaire-based measurement.

Clinical Trial Description

Low health literacy as a barrier to healthcare. Health literacy is defined as "the degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions." A vast body of research shows that lower health literacy is associated with poorer outcomes, including higher hospitalization rates, worse health, and greater mortality. Approximately 75 million U.S. adults have low health literacy. Worse yet, racial and ethnic minorities and older individuals (age 65+) are more likely to have low health literacy, creating another mechanism for health disparities. These data indicate that many people will have difficulties adhering to treatment regimens that require health literacy, as well as completing questionnaires for public health and health research and care. Improving self-report assessment. Health surveys are ubiquitous, but almost no questionnaires used across the country have been validated for use with people who have low health literacy. This is a glaring shortcoming in current survey validation methodology; inaccurate surveys lead to false conclusions and threaten the empirical foundation of everyone's efforts to understand and improve public health, healthcare, and health outcomes. Our goal is to rectify this shortcoming. This study will 1) determine the effect of health literacy on widely-used questionnaires, 2) determine the stability of psychometric properties of questionnaires over time, and 3) test various testing formats to determine which ones work best for people with low health literacy. Due to the COVID-19 pandemic, the study will implement phone-based assessments in addition to the original in-person protocol described above. The phone-based assessments will only be available to enrolled or previously enrolled participants. Participants will be asked questionnaires over the phone by a research coordinator at 3 time-points over 6 months. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
