This study investigated social cognitive

determinants of creatine supplementation

among 171 male, undergraduate, recreational

weight-lifters. Participants responded to a

packet of questionnaires that assessed their

history and rate of creatine use, self-efficacy

for improving their workout performance with and

without creatine, and expected outcomes of

improved workout performance and creatine use,

as well as several other demographic variables.

Fifty percent of the sample reported past creatine

use. The data was used to establish the internal

consistency, test-retest reliability and

predictive validity of factor-based scales for

valued outcome expectancies and disincentives for

creatine use scales. A social cognitive model was

shown to predict past creatine use (R2 = .372).

The results lay the groundwork for further

examination of the determinants of creatine

supplementation and the use of other controversial

and potentially harmful performance-enhancing

dietary supplements.
