What is Ego-Syntonic?

Question

I'm seeking to find information on the meaning of the terms 'ego-
syntonic' and 'ego-dystoni'. I wonder if you can help please.

Answer

In short,

The ego's job is to determine the best course of action based on information from the ID, reality, and the Super Ego (SE). When the ego is comfortable with it's conclusions and behaviors, (in denial in these sort of cases), one is said to be ego-syntonic. For example, an individual with borderline personality disorder (BPD) that is in denial, could be an ego-syntonic BPD. However, if the person with BPD were bothered by some of their behaviors, they would be an ego-dystonic BPD.
