Psychiatrists are known for being more detached than then other types of providers you list. Personally I think this is largely due to training with the medical model focus on medication. Since they attend medical school, psychiatrists receive little to no training in therapy. Social workers and licensed couselors hdon't really train in the medical model like PhDs and MD's, and that affects how they approach clients. It's a more balanced dynamic as well: service provider/client, rather than doctor/patient.
