Psychology is a board topic, having a Ph.D is psychology doesn't mean you will be good at analyzing people's mental states, that's a very specific application field.
Anyway, it is indeed dangerous to pretend to be a psychiatrist which delays patients from getting proper help, but in my opinion, psychiatrist's value often does not coincide with Christian teaching, which is the real danger. Therefore, I think it is important to give advice by bible's teaching, and quote from the bible if necessary.
This is a prayer room, but there is more to prayer than just the knowledge that someone will pray for you. In real life, we pray together and listen other's prayer which gives guidance and insight into the problem at hands.
So please encourage others to give advice and bible verse if it will be good for the well-being of the poster, and please do define what is 'psychoanalytical' level so that people wouldn't avoid giving any advices all together.
