What are some signs that a therapist may have poor boundaries with their clients?

These items can happen fleetingly, briefly, in any therapy, but if they’re frequent, it’s definitely time for the therapist to get some good, solid supervision/consultation.

General Introduction to Boundaries from Panahi Counseling:

Disclosing feelings, fantasies, and experiences to the client in ways not related to the work the client is engaged in.

Sense of competition with persons who are important in the client’s life.

Eager anticipation (or anxious anticipation) of the next session in ways that distract.

Serious disappointment when the client cancels a session.

Failing to mention the client in supervision/consultation, out of fear the supervisor/consultant will advise return to ordinary healthy boundaries.

Frequent phoning or texting of clients to “check up on them and make sure they’re OK.”

Session-expressed curiosities about client details not relevant to the therapy.

Obsessing about clients outside of work hours.
