Thirty-eight male-to-female (M-to-F)
transsexuals, 7 female-to-male (F-to-M) transsexuals, 135 nontranssexual
men, and 225 nontranssexual women were assessed on the following: gender
diagnosticity (GD) measures, which assessed male- vs. female-typical
occupational and hobby preferences; instrumentality; expressiveness;
self-ascribed masculinity; and self-ascribed femininity.
M-to-F transsexuals differed strongly and
significantly from nontranssexual men on GD and self-ascribed femininity
(effect sizes from 1.84 to 3.40) and more weakly on instrumentality,
expressiveness, and self-ascribed masculinity (effect sizes from 0.40 to
0.56).
F-to-M transsexuals differed strongly and
significantly from nontranssexual women on GD and on self-ascribed
masculinity and femininity (effect sizes from 2.45 to 3.97), but not on
instrumentality or expressiveness (effect sizes of 0.07 and 0.39). The
degree to which the six assessed gender-related traits distinguished
transsexual from nontranssexuals was strongly correlated with the degree to
which these same traits distinguished nontranssexual men from nontranssexual
women.
Using comparison data from past research,
M-to-F transsexuals were quite similar to gay men on all gender-related
traits except self-ascribed femininity, but F-to-M transsexuals were
considerably more masculine than lesbian women on all gender-related traits
except for instrumentality and expressiveness.
