Member compatibility was defined by "interchange compatibility" (Schutz 1958) on the three needs measured by FIRO-B scale.
Members and trainers of thirty one T-groups completed the FIRO-B scales at the beginning of the laboratories to assess control and affection needs; need scores from this measure were categorized as low control/low affection, low control/high affection, high control/low affection, and high control/high affection.
Each group leader was pre-selected on the basis of scores on the FIRO-B, which measured control and participation needs.
Since the FIRO-B theory and research instrument was developed by Schutz (1958), it has undergone material changes and expansions (Schutz 1992, 1994; Thompson & Schutz 2000).
The FIRO-B attribute of inclusion refers to a person's general social orientation and need for interaction and belonging.
The FIRO-B aspect of control refers to the need for power and influence.
The key benefit of FIRO-B to coaching is that it helps you identify the interpersonal issues in a group of people very quickly.
FIRO-B is available to anyone who completes the training, which is only a couple of days.
The FIRO-B (Schultz, 1958) consists of 54 items, 9 for each of the 6 scales.
Pearson correlation coefficients were computed on the combined matrix of the 6 FIRO-B and 5 BFI scales.
The second testing instrument, the FIRO-B, focuses on employees' behaviors.
The FIRO-B model essentially breaks behaviors into three categories: inclusion, control and affection.
