Klein, while recognizing that the grid explores many more dimensions of sexual orientation than previous scales, acknowledged that it omits the following "aspects" of sexual orientation: • Age of partner • Differentiation of love and friendship in the emotional preference variable • Sexual attraction being distinguished between
sexual desire and
limerence • Whether
sexual activity referred to number of partners or number of occurrences •
Sex roles as well as masculine and feminine roles Additionally, factors not addressed by Klein include: • Attraction to non-binary/transgender orientations. While Klein held the belief that including more dimensions of sexual orientation was better, Weinrich et al. (1993) found that all of the dimensions of the KSOG seemed to be measuring the same construct. The study conducted a
factor analysis of the KSOG to see how many factors emerged in two different samples. In both groups, the first factor to emerge loaded substantially on all of the grid's 21 items, indicating that this factor accounted for a majority of the variance. They further found that a second factor emerged containing time dimensions of social and emotional preferences, suggesting that those dimensions may have also been measuring something other than sexual orientation. Therefore, despite the scale being helpful in promoting the concept of sexual orientation as being multidimensional and dynamic, the additional dimensions measured do not necessarily reveal any more of an accurate description of one's overall sexual orientation than the Kinsey scale. Another concern with the KSOG is that different dimensions of sexual orientation may not identify all people of a certain orientation in the same way. Measures of
sexual attraction, sexual activity, and
sexual identity identify different (though often overlapping) populations. Laumann et al. (1994) found that of the 8.6% of women reporting some same gender sexuality, 88% reported same gender sexual attraction, 41% reported some same gender sexual behaviour and 16% reported a lesbian or gay identity. ==See also==
