<p>Yes, it has been updated. I suggest you read &quot;Seeing People Through&quot; by Dr. Nate Regier (2021) or Dr. Kahler's own book, &quot;The Process Therapy Model&quot; (2008) which described the development of the model from a clinical perspective. Both are available on Amazon. Regarding the NASA information, Dr. Terry McGuire, who was NASA's Lead Psychiatrist for Manned Spaceflight from 1959-1996 wrote a paper on the personalities of NASA astronauts and PCM, which is not publicly available. However, a listing (some with links) of books, articles, doctoral dissertations and other research that has been done on PCM can be found at <a href="https://www.atoire.com/copy-of-library" rel="nofollow noreferrer">https://www.atoire.com/copy-of-library</a>. I hope this is helpful.</p>

A brief summary of the underlying research (and results) would make this answer even better.

It is helpful, thanks! It doesn't quite answer my question on the scientific validity of PCM, but it does give me some threads to follow.

Do you have references for your further claims on the Big Five of the consensus of psychologists? It seems weird that personality would be static through life.

Are there valid scientific bases for psychologist Taibi Kahler's Process Communication Model?

(Asked by: username_0 on 2022-09-28)

In a corporate training course on team work, I quickly realized that the whole course was based on [Taibi Kahler](https://en.wikipedia.org/wiki/Taibi_Kahler)'s Process Communication Model. After a quick search, it seems to me that PCM is basically a commercial test used for convenience, that hasn't evolved or been updated since its conception. I don't have access to psychology publications (and wouldn't know how to read them).

Some specific claims that seem dubious to me, made by the teacher, are as follow:

* the basics of our personnnality is fixed by age three.
* NASA astronauts have high IQ (above 160), but very low emotionnal intelligence.

My questions are:

* Is there a valid scientific basis to PCM?
* Has it been updated since it was developped (in the 1980s?)?
* Is there somewhere where I can fact check that very specific claim about astronauts?
