Hello aspirant,

I hope that you are doing absolutely great.

With reference to your above mentioned query, i would like to tell you that you cannot use Dr prefix before your name after completing your diploma in any of the courses be it dietician or Psychology course.

further, I would like to tell you that if someone wants to put DR before their name then one has to complete their Ph. D. in Psychology, then one can use DR in their name .

So, if you want to use Dr as a prefix before your name, then you have to complete P.h.d.

I hope that this will help.
