Psychometric Correlates of FIRO‐B Scores: Locating the FIRO‐B scores in personality factor space

This paper investigated the relationship between the six Fundamental Interpersonal Relations Orientation (FIRO)‐B scales, the Big Five Personality traits assessed by the NEO PI‐R, the Hogan Development Survey (HDS) and two measures of cognitive ability (Watson Glaser; Graduate and Managerial Assessment). It examined the concurrent and construct validity of the measure in various adult groups attending assessment centres in order to locate the FIRO‐B dimensions in established personality factor space. The FIRO‐B was consistently correlated with Extraversion, though analysis at the primary factor (facet) level showed many traits from all five factors were strongly correlated with the six FIRO‐B scores. Regressing the six FIRO‐B facets onto each of the Big Five in turn showed all were significant particularly for Expressed Inclusion and Wanted Control. The second study also showed considerable and logical overlap between the six FIRO‐B scales and the 11 dysfunctional personality strategies as measured by the HDS. There were also strong correlational patterns for the Cautious, Reserved, Colourful and Dutiful type disorders. The third study showed the FIRO‐B was statistically associated with both cognitive ability tests though it only accounted for small percentages of the explained variance. Expressed Control was the most consistently correlated of the intelligence test scores. Despite the fact that many explicable associations were found between the FIRO‐B and other measure the effect sizes were not large. Thus only 4% of the trait facet scores and 4.5% of the HDS showed medium effect sizes. Results are discussed in terms of the usefulness and possible discriminant validity of the instrument for use in selection and assessment.
