the aim of this study was the adaptation to colombia of o'kelly women's beliefs scales (owbs), an instrument that measures the irrational thinking on the traditional female role. the colombian version of the scale was prepared using the reverse translation method and administered to 931 women aged between 17 and 70. exploratory factor analysis with varimax rotation yielded five factors that accounted for 45.57% of the total variance, based on 37 reactive with factor loadings above. 30. as in previous studies, the existence of a dominant factor that explains 30% of the variance is confirmed. the internal consistency of the scale and the derived factors was adequate, with cronbach's alpha coefficients between .79 and .94. in general, these results establish equivalence between the colombian version of the owbs and the original australian version. however, given the theoretical foundation of the scale and the magnitude of the correlation between derived factors, a grouping of items in two main factors is proposed- general irrational beliefs about the traditional female role (made up of four derived factors) and irrational beliefs about the traditional female role in the couple (based on the remaining factor)-. this hypothetical structure should be confirmed empirically in future research.
