Theory of Planned Behavior and Multivitamin Supplement Use in Caucasian College Females

Abstract: The objective of this study was to identify predictors of the use of multivitamin supplements among Caucasian college females utilizing the Theory of Planned Behavior. Variables of the Theory of Planned Behavior and the self-reported use of multivitamin supplements were measured by two separate surveys within one week. A convenience sample of 96 Caucasian college females were included in the analysis. Two attitudinal beliefs and one control belief significantly predicted behavioral intention to use multivitamin. A belief that taking multivitamin supplements helps to feel and look good was the most important predictor of the use of multivitamin supplements.
