The Fundamental Interpersonal Relations Orientation™ (FIRO®) instruments help people understand their interpersonal needs and how those needs influence their communication style and behavior.
The FIRO assessments address, gather, and present critical insights around these fundamental areas - 1) How you tend to behave toward others, and 2) How you want others to behave toward you.
The instrument was created by William Schutz, Ph.D. He developed the FIRO-B theory to aid in the understanding and predicting of how high-performance military teams would work together. Schutz began with the premise that “people need people,” and used the term interpersonal to indicate any interaction, real or imagined, occurring between people.
The current norm sample for the FIRO-B instrument includes a U.S. national sample of 3,091 individuals who took the assessments in 1997 (Hammer & Schnell, 2000). In examining the internal consistency reliability of each measure for the national sample, results indicate that reliability coefficients for all measures are good, ranging from .85 to .96. Test-retest reliability coefficients also demonstrate good reliability – ranging from .71 to .85 – for three different samples reported in the FIRO-B® Technical Guide (Hammer & Schnell, 2000).
