Match trust to each of the six IVs and test the effect on the purchase intent. The level of significance will give an insight as to the best perception and reliability of any given variable. Then suggest how each variable affect the other and the overall effect on the DV.
Dear Nipul, your current model assumes that the 6 exogenous variables influence purchase intention indirectly through "Trust". To posit mediation, you need to first posit a direct effect of the 6 exogenous constructs on Purchase Intention. Then, you need to check whether a full or partial mediation exists.
You must perform the relationship between the variables as a previous step for mediation models, I recommend you to use the free program JAMOVI because it includes generalized mediation models and structural equation models.
