Zur uses his pulpit as an actively fervid advocate for looser boundaries between therapist and client down to rejecting the long-held idea of the slippery slope. His writings are, like everything else, a guy's opinion.

Beyond ethics rules and guidelines for each professional organization, providers explore and debate these issues themselves, with no universal consensus.

Unlawful and/or Unethical Dual Relationships

Boundary Crossings and the Ethics of Multiple Role Relationships - by Gerald P. Koocher, Ph.D. and Patricia Keith-Spiegel, Ph.D.

The less nasty of my therapists violated (or crossed) a number of boundaries, hosting a party for single clients (I couldn't attend) and other match-making, attending my outside event, inviting me to a family occasion and even encouraging my joining a small in-home congregation where she was a member. (Nothing cultish.)

I can't claim long and devastating damage. However it contaminated the professional purpose of the relationship--I was her sycophant both in therapy and out. Though I had my own social currency, this definitely was not a relationship between equals. I'm certain this looseness affected how she treated me, maintaining a sort of idealized "friendship" that never was. In retrospect, it feels delusional on her part, and I don't think she should have used her practice to quarry for social contacts.

Someone else apparently reported this therapist because she received a warning from her state licensing board.
