The purpose of this study was to determine consumers’ brand preferences for three brands of breakfast bars: South Beach Diet, Pria, and Nature's Valley. Preferences were determined from respondents’ purchase intent and attitudes pre- to post-exposure of print advertisements for each brand as well as through ten Likert and attitude questions for each brand. 

There was a total of 63 respondents; they were asked to fill out the online survey via e-mail, Facebook and MySpace.  Successfully submitted surveys were collected into a database. Due to time constraints there was no control group to compare with the convenience sample of respondents.The database was then compressed and analyzed on SPSS.

Using SPSS, several statistics techniques were used to analyze the collected data, including the calculation of basic statistics, regression analysis, discriminant analysis, and factor analysis.  Throughout the analyses, Pria had the largest differences in attitudes from pre to post exposure of the print advertisements, there was also a down-trend in post-ad exposure towards Nature's Valley, however consumers said they would still purchase Nature's Valley and they also maintained high attitudes towards Nature's Valley.
