Dental health knowledge tests: their development, implementation and evaluation.

Area of Science:

• Public Health
• Dental Education
• Educational Measurement

Background:

• A gap existed in validated dental health knowledge assessments for elementary grades (K-6).
• Effective school-based dental health programs require reliable cognitive measures.
• Understanding dental knowledge's impact on behavior is crucial for public health initiatives.

Purpose of the Study:

• To develop and validate new dental health knowledge tests for grades K-6.
• To create parallel assessment forms for measuring dental concepts precisely.
• To support a school-based dental health delivery system's effectiveness evaluation.

Main Methods:

• Literature review to identify existing assessment gaps.
• Development of 14 objectively scored dental health knowledge tests by project staff.
• Administration of parallel test forms to 1,942 students across seven grade levels (K-6).

Main Results:

• The newly developed tests demonstrated high reliability estimates.
• Low standard errors of measurement indicated precise assessment.
• Instruments functioned effectively as parallel forms, measuring dental concepts with equal precision.

Conclusions:

• The developed dental health knowledge tests are reliable and valid for grades K-6.
• These instruments can accurately measure dental health knowledge in school settings.
• The tests provide a foundation for evaluating dental health education effectiveness and behavior links.
