Abstract
The purpose of this investigation was to partially replicate and elaborate upon a validation study of the FIRO-B Questionnaire reported by Kramer. (1967a) The 25 Ss employed in this study were administered the FIRO-B Questionnaire, given a brief lecture on the theory behind the instrument and then directed to estimate their scores on the three FIRO-B dimensions. Rank order correlations were calculated between the measured and estimated scores. Contrary to Kramer's findings only one of the six resulting coefficients attained significance at or beyond the .05 level of confidence. A recent finding in the estimated and measured test score approach to test validation studies, namely scale relevance to individual Ss, was proposed as a possible explanation for the inconsistent results. A partial replication of the Kramer (1967a) test validation study of the FIRO-B Questionnaire yielded a significant relationship between estimated and measured scores on one of the six scales of the instrument, namely, expressed control (Ce). These results contrasted markedly with the findings reported by Kramer. It was suggested that the inconsistent results might be explained as a function of differential scale relevance (Foreman and James, 1969) for 5s in the two different studies. Further investigation of that possibility was encouraged.
