Belbin Self Perception Inventory
This report attempted to examine the psychometric properties regarding the extensively used, but bit tested, Belbin (1981) Team-Role Self-Perception stock which examines how individuals act in groups. The first 56-item stock was given to over 100 people from multiple backgrounds in a non-ipsative Likert scaling form. The alpha coefficients for the eight roles are not impressive and factor evaluation couldn't offer obvious evidence of the recommended framework. The 2nd test tried the same non-ipsative evaluation aided by the more modern 70-item type of the survey which includes nine group roles. Again the alpha coefficients were moderate and the factor analysis suggested a more simple solution than suggested. Team-role scores did not correlate significantly with a large number of demographic factors any more than may be expected by chance. A third test utilized the initial scale with the original ipsative scoring system using full-time supervisors as topics. Once again alpha amounts had been low, intercorrelations not as predicted and factor framework ambiguous. Ramifications among these conclusions are talked about.
