A Study of Factorial Structure (Construct Validity) and internal consistency of the Bem Sex-Role Inventory in Iranian teenage population

 The present study aimed to investigate the factor   structure and determining the internal consistency of the Bam Sex-Role   Inventory (form 30 items). The study method is descriptive and correlation   research for the analysis of covariance matrix. Data were collected from 402   students of high school in 2017-2018 by stratified-cluster sampling. To   determine the factorial validity, Confirmatory factor analysis (CFA) and   exploratory factor analysis (EFA) were used. In order to determine the   internal consistency, Cronbach's alpha coefficient was used. The findings   showed that Bam's theoretical model was not fitted with collected data, In   contrast to the obtained model from exploratory factor analysis showed   acceptable fit with data. The Cronbach alpha coefficient in the whole inventory, the masculinity and femininity subscales was   respectively 0.70, 0.70 and 0.61. The results of the research repeated the findings of some previous   studies about the BSRI-dependent culture and the extraction of a different   factorial structure than theoretical logic. Regarding the non-fit of Bam's theoretical model, the inappropriate   patterns of the coefficients in some items and the low correlation of some   items with the whole scale, the BSRI Form 30 should be revised to evaluate   the gender characteristics of Iranian adolescents.
