Mawali pretty much got it.

The entry in the DSM was probably made so those treating Chinese patients could put a diagnosis to something. It is doubtful that any insurance or third party copayer would accept that particular diagnosis (at least in the west...no telling what would happen in someplace like Singapore).

But what you do get from having it is a nice place for the mental health professionals in China to get hooked in to the whole DSM process - statistcs, tracking...and eventually coopting them into the western view of psychiatry.

while this may sound weird, in the PRC, anti-psychotic drugs are expensive and not readily available. They also tend to prescribe lower doses for similar patients than do their western counterparts.

The main mode of treatment is to use the drugs to get a level of normal functioning and then switch into the "Long Discussion" ---or some such phrase which basically means very deep one on one sessions with a therapist (or lay-therapist) - and this tends to be closer to reality therapy than strange things like...oh...Freudian analysis

But, western psychiatric treatment is more geared to the 45 minute hour, pills, and not spending the depth of time needed with each patient. In a western setting, if the patient hits on something that is a breakthrough at 44 minutes into the hour, the therapist is winding down and talking about picking up there next time (meaning that it takes that much longer).

In the Chinese version, they tend to keep going and actually accomplish something. Part of this is the culture and philosophy. The other part is that it is of no advantage in China for a therapist to drag treatment out for years or to have a relapse. They don't have the insurance/get rich on the patient approach.

When you see a psychiatrist come into a hospital where their patients are and hit one floor after another...starting at the top and working down...and then having the nursing staff round up their patients on each floor and herd them in one at a time...for 5 minutes max....and then realize that each patient was charged for a 45 minute hour PLUS the charge for hospital treatment from the shrink, you begin to see how the mental health field has a big racket going on.

And the really good therapists are the ones that get burned out and leave the field

I have studied some TCM and follow my Qi Gong teacher who is a TCM doctor and was a founding teacher of the Shanghai College Of TCM....before he retired. - to answer the question...
