Collected data were analyzed using SPSS/WIN 22.0, AMOS 22.0 program.ResultsThe assessment of the model indicated an acceptable fit (normed χ2=1.65, goodness-of-fit index [GFI]=.83, adjusted GFI=.79, comparative fit index [CFI]=.92, standardized root mean square residual [SRMR]=.05, Tucker-Lewis index [TLI]=.91, normed fit index [NFI]=.87, root mean square error of approximation [RMSEA]=.07). Perceived behavior control, subjective norm, the subjective attitude was found to have a significant direct effect on the intention to discontinuation of drinking a high caffeinated beverage. The variances of this model explained 45.3% of the variance in intention to discontinuation of drinking a high caffeinated beverage.ConclusionThese results suggest that a need to increase awareness of adverse effects and potential risks of high caffeinated beverage consumption in undergraduate students.
