Metrijske karakteristike inventara polnih uloga – BSRI

Abstract

U cilju provere metrijskih karakteristika Inventara polnih uloga autorke Sandre Bem, oko kojih u literaturi postoje brojne kontroverze, originalna verzija upitnika je zadavana uzorku od 329 učenika četvrtog razreda beogradskih gimnazija. Analiza interne konzistencije stavki pokazuje da instrument ima dobre metrijske karakteristike: pouzdanost, valjanost i reprezentativnost. Analiza glavnih komponenata uz primenu Varimax rotacije faktora pokazala je, međutim, da u osnovi instrumenta ne stoje dve latentne dimenzije kao što teorija pretpostavlja, već devet. Takođe, svaka subskala instrumenta ne predstavlja jednodimenzionalni, već multidimenzionalni konstrukt. Rezultati ove studije govore da je instrument BSRI pouzdan instrument za merenje polnih uloga, ali da nije invarijantan prilikom primene u različitim kuturnim kontekstima tj. da ima slabu konstruktnu validnost.

In order to assess validity, representativity and factor structure of Bem Sex Role Invetory, which is an object of conrtoverse in the literature, original version of the inventory was given to a sample which include 329 adolescence of Belgrade grammar schools. The results of the item internal consistency analysis carried out so far has showen that Bem Sex Role Inventory has still good metric charachteristics: reliability, validity, representatitvity. Principal component analysis with Varimax rotatiton yielded the nine factor solution, showing that the basis of the inventory consists of more that two latent dimensions, opposite to the presumption of the theory. Also, each subscale of the inventory is not unidimensional, but multidimensional. Resuts of this study showed that BSRI represents a reliable instrument for gender role measurement, that it is not invariant by aplicationa in different cultural contexts, i.e. offers a weak construct validity.
