Personality Plus is Florence Littauer, and is loosely associated with LaHaye, I believe. She adds nicknames to the temperaments: "
Perfect Melancholy" "
Powerful Choleric" "
Popular Sanguine" "
Peaceful Phlegmatic". Neither she, nor any of the others use Supine. That is specifically Arno Profile system (which is based on FIRO-B), and now a couple of bloggers are hosting this scaled down test using the five temperaments.
There's also another one out there, the Worley Profile, which calls the fifth temperament, "Introverted Sanguine'. I've also just found "five Toddler Temperaments".
The Five Toddler Temperaments
This is probably unrelated, though they are similar. (Angel=Phlegmatic; Texbook=Supine; Touchy=Melancholy; Spirited=Sanguine; Grumpy=Choleric).
When I first saw Keirsey's temperaments; I was greatly thrown off by the fact that each temperament was evenly divided between introverts and extraverts. How could the "Sanguine" SP have four introverted types, and the "Melancholic" SJ have four extraverted types?
But then I learned about the Interaction Styles, which also correspond to the four temperaments, but are in fact drawn along the lines of I and E; along with another factor, Directing and Informing (which basically is T/F for Sensors, and J/P for iNtuitors). The old temperament theory of LaHaye and Littauer are based on I/E and D/Inf. (the latter under other names, such as "people/task focus"). That's why they are either all introverted or all extraverted. I've found that
the "expressive/reserved" (I/E) counterparts for the Keirsey temperaments are Cooperative/Pragmatic, tying together SJ with NF and SP with NT. Like I/E, they do shape how aggressive or passive a person is in situations (like Keirsey's descriptions "do what's right" vs "do what works").
LaHaye, however, does have 12 two way blends (which you can see here:
Profile Dynamics with a couple of them listed twice, and one three-way blend thrown in, and corresponding DISC letters), which result in 16 "types". APS, using FIRO's "Inclusion", "Control" and "Affection" also result in blends. If you take expressed Inclusion as I/E; then a person can be Melancholy in Control; yet still an extravert. (this would basically be an ESJ).
These are the resultant correlations I would expect:
ISTJ Pure Melancholy (My family and several friends)
ISFJ Phlegmatic*/Melancholy ("PhlegMel")
INFJ Melancholy/Phlegmatic* ("MelPhleg")
INTJ Melancholy/Choleric ("MelChlor")
ISTP Melancholy/Sanguine ("MelSan")
ISFP Phlegmatic*/Sanguine ("PhlegSan")
INFP Pure Phlegmatic*
INTP Phlegmatic*/Choleric ("PhlegChlor")
ESTP Choleric/Sanguine ("ChlorSan")
ESFP Pure Sanguine
ENFP Sanguine/Phlegmatic* ("SanPhleg")
ENTP Sanguine/Choleric ("SanChlor")
ESTJ Choleric/Melancholy ("ChlorMel")
ESFJ Sanguine/Melancholy ("SanMel")
ENFJ Choleric/Phlegmatic* ("ChlorPhleg")
ENTJ Pure Choleric
*(May also be fifth temperament, Supine)
The last several results seemed to go against this notion

(with the exception of INFP as Phlegmatic!

) INTJ as Melancholy-Phlegmatic-Supine instead of Melancholy-Choleric would seem to favor Keirsey's theory about the NT.

uch:
But of course, there's many reasons why they might not match. (Considering that people can come up completely different MBTI types with different tests). For an ISTP, for instance, the Pragmatism of the SP is a kind of "expressiveness", while the ST is directive (task-oriented); hence, having an appearance of "Choleric" traits (Choleric is extraverted and directive; just replace extraversion with pragmatism). INTP seems Melancholic because it is introverted and yet another facet called "Structure-focused" (which ties together SJ and NT, and is the [S/N] "mirror" of "Directive".
This test is not the full one dividing between Inclusion and Control, so it might come out with the factors meshed together like that. They're still overall not too far, though.
