The FDA's Message Testing: Putting Health Literacy Advice into Practice.

Area of Science:

• Health Communication
• Health Literacy
• Public Health Practice

Background:

• Effective health communication is crucial for public health agencies.
• Implementing health literacy principles in practice presents unique challenges for large organizations.
• The U.S. Food and Drug Administration (FDA) operates within a complex regulatory environment with time constraints and diverse audiences.

Purpose of the Study:

• To explore practical methods for applying health literacy principles within a large governmental agency.
• To describe the FDA's approaches to testing public health communications with intended audiences.
• To evaluate the utility of internal and external message testing for improving health messages.

Main Methods:

• The report outlines the FDA's experience with message testing.
• Two primary methods are discussed: internal message testing with employee volunteers and external message testing with consumer panelists.
• The process involves assessing communications to gain audience insights and identify areas for modification.

Main Results:

• Message testing is a fundamental responsibility for ensuring effective communication.
• Internal and external message testing provide valuable insights into audience comprehension and message usability.
• These testing methods are feasible within a large governmental agency's operational constraints.

Conclusions:

• Practical implementation of health literacy requires creative application of research findings.
• Internal and external message testing are superior to no testing (controls) for refining health communications.
• The FDA's experience demonstrates that message testing can be successfully integrated into agency practices.
