Anger groups are usually straight forward …. OK, no group is like that. They each have their own dynamics which are dependent on many factors.
I used to work as a float at a hospital and would walk onto a unit to facilitate a group of (usually) adults with a mix of diagnoses none of whom I had ever met before. In those situations I usually keep it very basic and thus very safe.
