" In fact, the same intervention or response may even have the opposite effect on two different clients with contrasting developmental histories and cultural contexts. For example, if a client’s parent was distant or aloof, the therapist’s judicious self-disclosure may be helpful for the client. In contrast, the same type of self-disclosure is likely to be anxiety-arousing for a client who grew up serving as the confidant or emotional caregiver of a depressed parent. Greater sharing with the therapist may help the first client learn that, contrary to her deeply held beliefs, she does matter and can be of interest to other people. In contrast, for the second client, the same type of self-disclosure may inadvertently impose the unwanted needs of others and set this client back in treatment as, in her mind, she experiences herself back in her old caretaking role again—this time with the therapist. This unwanted reenactment occurs because the therapeutic relationship is now paralleling the same problematic relational theme that this client struggled with while growing up. "
