In 2005 a survey was used to investigate social norms and attitudes of Viennese high school students (14-20 years, n = 340) toward organic products. Young people, who already participate in household decisions and consume organic products, have not yet been recognized sufficiently in research. The Theory of Reasoned Action and discriminant analysis are used to explore relations of a number of variables and the complex field of factors influencing Viennese high school students' shopping behavior when shopping for organic products. Key findings include the importance of primary socialization in forming social norms and shaping behavior. Surprisingly, knowledge of organic products does not explain students' self-reported shopping behavior when shopping for organic products. Cultural patterns seem to be far more useful to predict behavior and attitudes toward organic products. (Contains 1 table, 2 figures and 2 notes.)
