Spearman correlation coefficient and linear regression methodwere used to test the study hypotheses.Results: The constructs of attitude, subjective norms, and perceived behavioral control wereaccounted for 37.8% in variation of fast food consumption intention. The construct of subjectivenorms and perceived behavior control was significantly associated with intention of FFC.Intention of FFC was significantly associated with behavior (B coefficient = 0.76,P-value = 0.001) and predicted 63.8 % of the variance of fast food consumption behavior.Conclusion: The present study showed that the TPB is a powerful theory in predicting FFCbehavior. Subjective norms followed by perceived behavioral control were the strongestpredictors of FFC intention.
