I think anyone who believes a prescribing physician has any real clue about medication for psychological contexts -- they're in denial of the reality that is pharmaceuticals.
I'm not talking any conspiracy type nonsense... just the facts. There is very little hard evidence that support most psychological based medication on the market, let alone those medications being prescribed off-label. Most of the information is theoretical, limited testing, and relies on patient feedback vs. science. People don't know their arse from their head, most days -- let alone feedback from leading questions.
SSRI's have been around a long time now -- their trail of destruction is pretty much well documented that they do not work on the majority. If this was physical medicine, these medications would have been banned long ago. Because they're psychological, they continue getting away with the excuse of, "they're better than nothing." Which is false to be honest, compared to known medications that are working outside the SSRI group, and specifically trying to treat depression -- something that is unproven in physical medicine compared to what they claim to be treating with the medication.
Wrong isn't a strong enough word for what's going on in psychological medication prescribing.
