Objectives:
To determine factors that influence sport-related dietary supplement consumption among NCAA Division 1 female student athletes and to estimate the plausibility of the theory of planned behavior (TPB) for predicting the use of sport-related dietary supplements among NCAA Division 1 female student athletes.
Method:
Self-report data were collected by questionnaire from 207 NCAA Division 1 female student athletes. Parameter estimates of 3 TPB-based models were calculated using Mplus software.
Results:
The TPB-based models explained 64-66% and 18% of variance in behavioral intention and behavior, respectively, with subjective norm being the strongest predictor of dietary supplement consumption intention.
Conclusions:
Results support plausibility for the TPB to predict sport-related dietary supplement consumption among NCAA Division 1 female student athletes.
