Hi Nida Hussain ,

You can use Structural Equation Modeling (SEM). Here is details:

Article Introduction to mediation analysis with structural equation modeling

But regression analysis is suitable here too. Good luck

@Nida Hussain I suggest you use Smart-PLS to test your model. It offers to run Moderation and mediation analysis at the simultaneously. Through Smart-PLS, you would be able to test your entire model at once. Though it's paid software, but you can use one month trial for no cost.

@Kaislash Jandu @Nida HussainTrial version of Smart-PLS doesn't restrict in terms of sample size or any other feature and works similar to paid version. Moreover, AMOS doesn't provide an option for adding moderator when running a model with latent factors. Therefore, for moderation in AMOS, one needs to create product variable (IV*Moderator) of IV and Moderator then run a path analysis taking observed variables.

Dear Nida Hussain though Multiple options including Hierarchical Regression and SEM (PLS or Factor Based) are available, none of these strictly perform Moderated-Mediation as is the case in your model. Hayes' PROCESS macro is one good option (though with its own limitations). The use of a statistical tool depends on your objectives and acceptability in your situation.

you can use structural equation modeling which is the best way to investigate moderator and mediator.amos is best software to do this but you need a macro, or you must calculate manually.
