This is just my opinion,
but I think it depends so so much on the client and where they are coming from, whether self-disclosure should happen or not.
To me a good therapist should get to know the client and then determine whether or not a bit of self- disclosure would be beneficial for the therapeutic process.

Speaking for myself I would NOT be able to open up or trust a therapist that I knew nothing about-- that's my paranoia. If I disclose-- then the one I'm talking with should disclose,-- at least a little--- or I will push myself further and further from the process-- I don't trust one enough to be open with them if I know NOTHING about them.
I stayed almost 3 years-- with the last psychologist I had-- and I know it's partly due to his self-disclosure that helped the connection and keep me involved for such a "record" long time for me.

So I think it depends on each clients emotional state and how they are able to "bond"...... I do have difficulties with such things...... goes way back to my infancy...

just my opinion...

on another note.....Pinksoil-- I think you sound like you will be an awesome therapist-- I wish you the best.
