The current environment may promote adolescent palate preferences for highly marketed, energy dense foods and sugar‐sweetened beverages. The present study developed and examined the construct validity of a food preference survey to estimate adolescent’s willingness to eat these items. Five focus group interviews with 13 to 19 year‐old male and female high school students were conducted. A list of 5 items representing each of the following was developed: energy‐dense foods, energy‐dilute foods, sweetened beverages, and unsweetened beverages. The final survey instrument was administered to 234 public high school students. Willingness to consume each of the 20 items was assessed using a 7‐point Likert Scale with 1 representing “Extremely Unwilling” to 7 indicating “Extremely Willing.” Exploratory Factor Analysis using Principal Axis factoring with a Promax (oblique) rotation found two factors. Factor one included French fries, Kool‐Aid, glazed donuts, cookies, lemonade, and pizza (23.9% of the variance). Factor 2 included nuts or peanut butter, low‐fat or fat‐free yogurt, grapes, and bananas (13.8% of the variance). Internal consistency measured by Cronbach’s alpha was 0.770 for factor 1 and 0.664 for factor 2. The factor explaining most of the variance included foods processed with added fat and/or sugar.
