i was in a process group that my T facilitated for like 2 years or so. he was very different in the group than in individual therapy . what i mean is he was much more of an observer in the group and didnt speak up much. he let us talk and figure things out etc. he would ask certain people what they thought about what someone was saying or comment on body language and nonverbal stuff. he would talk about the themes of the group at the end. that was his method of running a process group. in individual he is much more interactive.
