Objective: Develop a valid and reliable scale to assess the attitudes, beliefs, and behaviors related to eating foods associated with the periodontal disease among low-income women in Texas. Study Design: This is a cross-sectional study. Methods: The study was conducted with 150 low-income women ages 18-50 years, residing in Central Texas. A 21-item Dental Nutrition Attitudes, Beliefs, and Behaviors Scale was developed. Content validity was assessed by a panel of experts. Construct validity was determined via Exploratory Factor Analysis; internal consistency of the scale was measured by Cronbach’s alpha. Results: The internal consistency for the final scale was 0.802, and the test-retest reliability was 0.99. Factor analysis generated three factors: Attitudes, Beliefs, and Behaviors, with an explained variance of 42.38. Conclusions: These results confirmed the validity and reliability of the new dental scale. This instrument may aid in the assessment of attitudes, beliefs, and behaviors regarding eating foods associated with periodontal disease in low-income women.
