In the present study the construct validity of the revised edition of the Belbin Team Roles measure, the so-called Interplace II program, is tested. Three parallel parts were used to determine someone’s team roles. The sample included 1434 persons who were asked to fill out the self-perception inventory and the self-perception assessment, whereas the observer assessment sheet was filled out by at least four observers. The inter-rater reliability appeared to be satisfactory across all team roles. As for the construct validity, which was studied in a multitrait-multimethod design using structural equation modeling, the results revealed that the discriminant and convergent validity for the instrument as a whole is good; only a small effect could be contributed to method variance.
