yes it is legal and ethical to all of the above. the treatment provider just has to prove how and why they are doing it.

for example there was a time when I was questioning my religious beliefs during therapy sessions.. my treatment provider got permission from her supervisor and the agency governing mental health treatment providers in my location to research various religions in the area, attend services with me. we had a very hard time finding a satanic based church because they are pretty much gone now in NY state. But we eventually found a satanic sect. they did nothing different than any other religions other than who their higher power was. I found out an interesting fact about this religion in that they have to follow the state and city/ town laws in which they practice. so Alot of what I read about in preparing for my therapist and I attending their service turned out to be no longer done nationwide because the old ways are now illegal. they would not be a church if they continued to practice the illegal activities of the past.

to a bar or club it was actually my idea that my treatment provider go to a bar or club with me. at the time I had an alternate personality that took control only during bar hopping and clubbing. We needed to get some issues taken care of with this alternate personality that we could not get cleared up any other way.

when we checked with her supervisor and the agency that governs treatment providers in my location both said yes. we had some limits such as since it was therapy work we could not drink any alcoholic beverages and uphold the same standards as being in therapy at the office.

concert sure, one of my past therapists went with me to a school concert in my home town because I was afraid of running into my one of my abusers.

you have to understand something...in many towns in NY state the person you grew up with as your best friend went out of town to college, became a treatment provider and then returned to the small town to be that towns treatment provider. when its a professional thing where the treatment provider is inviting the client to an event because the client has a problem they need to work out around that event, they know how to stay with in their profession during that time. they also know how to keep work out of their off duty time too.
