    The Test of Patient Knowledge is a valid and reliable tool for assessing diabetes patient understanding across key areas like nutrition and exercise. It is sensitive to learning and readable for most adults.

    Area of Science:

    • Psychometric evaluation
    • Diabetes patient education research

    Background:

    • Assessing patient knowledge is crucial for effective diabetes management.
    • Existing tools may lack comprehensive psychometric validation.

    Purpose of the Study:

    • To report the psychometric properties of the Test of Patient Knowledge.
    • To provide evidence for the test's validity, reliability, and readability.

    Main Methods:

    • A 50-item, multiple-choice test assessing seven diabetes content categories.
    • Analysis of content, concurrent, and discriminant validity.
    • Reliability testing using Cronbach's alpha.

    Main Results:

    • The test demonstrated strong validity and high reliability (Cronbach's alpha = .88).
