The current study tested the hypothetical model explaining the causal relationships among sustainability-related components for Turkish university students. In order to find out the strength and direction of the relationships among latent variables, path coefficients were calculated. The significance of these coefficients was evaluated through t-tests. To revise the model data fit, modification indexes were also considered. The paths from Attitudes and from Media to Values; and from Gender to Behaviors were found to be non significant. Therefore, these paths were deleted from the model. Finally, the model presented in Figure 4 was obtained with 0.96 GFI, 0.93 AGFI, 0.043 SRMR, and 0.043 RMR fit index values.
