The Firo-B (Fundamental Interpersonal Relations Orientation -- Behavior) test is another measurement tool often used to add more specification to the standard MBTI.
Firo-B has been around since the late 1950's and assumes that individuals are motivated by three interpersonal needs: Inclusion (I), Control (C), and Affection (A). Each of these needs can also be separated into Expressed needs (i.e., how much the individual is likely to express the trait) versus Wanted (i.e., how likely the individual is to want others to express the trait towards them).
The six traits can be described as follows:
An interesting 1994 study explored linkage between Firo-B and MBTI. One sample included 14000 managers participating in a leadership dev program over 11 years, while the other involved a sample of 386 managers who participated at another program. Cross-section demographics tended to show white males, young/mid-40's, college, educated, drawn from middle/upper ranks of their organizations. Most common types were ISTJ, ESTJ, and ENTJ.
- Expressed Inclusion (eI); I make an effort to include others in my activities, to belong, to join social groups, and to be with others as much as possible.
- Wanted Inclusion (wI): I want others to include me in their activities, to invite me to belong, and to notice me.
- Expressed Control (eC): I make an effort to exert control and influence and to organize and direct others.
- Wanted Control (wC): I want others to provide well-defined work situations and clear expectations and instructions.
- Expressed Affection (eA): I make an effort to get close to people, to express personal feelings, and to be supportive of others.
- Wanted Affection (wA): I want others to act warmly toward me, to share their feelings, and to encourage my efforts.
Taken from Schnell, Eugene R., and Hammer, Allen L., "Integrating the FIRO-B with the MBTI" in "Developing Leaders" eds Catherine Fitzgerald and Linda Kirby, Davies Black Publishing: Palo Alto, CA, 1997, p.440.
- Extroversion was related to higher scores on all Firo-B dimensions except Wanted Control.
- Feeling was positively related to high scores on both dimensions of Affection.
- IxTx had lowest levels of both Affection dimensions.
- Judging was NOT shown to be significantly related to Expressed Control.
- Expressed Control was determined to be related to ExTx.
- Thinking had the highest need for Expressed Control.
- Sensing was not related to Wanted Control.
- Feeling was significantly associated with Wanted Control.
- Highest levels of Wanted Control associated with ISFx types; lowest levels, with all NT and ST combinations.
- xNxP was significantly associated with Wanted Inclusion.
- Wanted Affection was the first or second highest interpersonal need for all 16 types.
Finally a summary of the highest one or two FIRO-B cell scores for each MBTI type:
- xNTx: (1) Expressed Control, (2) Wanted Affection
- IxFx: (1) Wanted Affection
- ExFx: (1) Wanted Affection, (2) Expressed Inclusion
- ISTx, ESTP: (1) Expressed Control, (2) Wanted Affection
- ESTJ: (1) Wanted Affection, (2) Expressed Control
Sorry if the middle part (conclusions) feels a little jumbled, I'm trying to condense an entire paper into one small post.
