Which tools are commonly used to assess health literacy?

• A. REALM
• B. TOFHLA
• C. NVS
• D. REALM, TOFHLA, and NVS

Answer: (D)

Assessing health literacy involves understanding how well a person can obtain, process, and understand health information. Several validated tools are commonly used for this purpose because they evaluate different aspects of literacy in practical health contexts. REALM measures word recognition and the ability to pronounce medical terms, giving a quick sense of reading capacity in a health setting. TOFHLA explores reading comprehension and numeracy through actual health-related materials, providing a more thorough look at functional health literacy. NVS uses a nutrition label in a brief scenario to gauge both literacy and numeracy in a real-world task. Each tool has its own strengths and is used in different circumstances, so using all three offers a more complete assessment of a patient’s health literacy than relying on a single instrument. In practice, you might choose a quick screen like the NVS or REALM first and then consider TOFHLA if a deeper evaluation is needed.
