I had a close friend who became a psychiatric nurse practitioner. In general, nurses come from a field that is more about serving patients than controlling them. As a prescriber, I believe she genuinely thought she was helping others. One of our coworkers was also a psychiatric nurse practitioner and very into yoga and Eastern metaphysics. Both held a perspective of valuing psychiatric meds and believing they had efficacy, but they didn't come from the same stance of a doctor in being authoritative and knowing everything better than the client. I think they believed they knew better in a lot of ways, but they were much more open to the clients having a say in their treatment and being flexible in treatment.
On a side note, the close friend I had invited me as her plus-one to a pharmaceutical-sponsored dinner. She got such a laugh out of it and so did I. Since she worked in community mental health and not in private practice, so she couldn't be swayed to get rewards for handing out meds, but the fancy dinner was clearly a tool of persuasion. It was a very expensive restaurant, one of the best in the city, and the meal was outstanding. Wine was provided as well. We sat through a long PowerPoint presentation about how awesome the medication was, and then we ate and drank -- reward conditioning,being used on psych practitioners! The event was also meant for networking, so practitioners would be more likely chat there about the med and to support one another in prescribing it while feeling good from that reward, as well as to go out and share that information with other mutual professional acquaintances not in attendance. "Oh yeah, I think this is great, and our buddy was there and s/he agreed it was great, too."
