ABSTRACT
This study aimed to evaluate the Free Drawing method to assess food consumption information compared to the Free Listing method. Furthermore, the citation frequencies of dairy products consumed by adolescents were compared in Brazilian regions. Adolescents (14-17 years old, n = 265, n = 53 for each region, North, South, Northeast, Midwest, and Southeast regions) listed or drew the dairy products they consumed using Free Listing or Free Drawing. The contingency tables were constructed, and the cognitive saliency indexes (CSI) were calculated. Multiple Factor Analysis (MFA) was performed, and the RV indices were determined. The adolescents listed/drew 55 dairy products, grouped into 10 categories. The Free Listing method resulted in greater citation frequencies of dairy products. The Free Drawing method resulted in richer and more detailed information, with specifications of the type of product consumed within the category, flavor, type of packaging, and brand. The dairy products with the highest citation frequencies/CSI by adolescents were milk, cheese, and fermented milk. The South and Southeast regions observed greater citation frequencies and diversity of dairy products (prevalence in 6 categories). The CSI did not depend on the method, but it was affected by the region (p < 0.05). The sensory methods showed high similarity considering the categories of dairy products (RV = 0.80) and regions (RV = 0.79). It is concluded that the Free Drawing method proved to be an alternative to Free Listing for evaluating adolescents' consumption information of dairy products in an intracultural study in Brazil.
