Several aspects of the Gender Diagnosticity (GD) approach of Lippa (1995) to measuring the psychological trait of masculinity-femininity within sexes were explored in four samples ranging from 363 to 5,859 individuals, including Swedish and Australian adults, U.S. elderly, and Australian adolescents. Two ways of deriving GD scales yielded highly similar results. Moderate stability of individual differences was found across ages 12 to 16 among adolescents, but substantial shifts over age… Expand
Individual Differences in Personality Masculinity-Femininity: Examining the Effects of Genes, Environment, and Prenatal Hormone Transfer
TLDR
Genetic influences explain part of the individual differences in personality M-F, and hormone transfer from the male to the female twin during pregnancy may increase the level of masculinization in females. Expand
[Gender differences in genetic and environmental etiology of gender role personality (BSRI)].
TLDR
No evidence was found to support the prenatal hormonal hypothesis or the existence of parenting which encouraged children's gender role personality, and the data did not support a model which explained gender differences in the effects of specific common environment factors. Expand
The Biological Contributions to Gender Identity and Gender Diversity: Bringing Data to the Table
TLDR
It is hypothesized that gender identity is a multifactorial complex trait with a heritable polygenic component and is relevant to all domains of social, medical, and neuroscience research and foundational for reducing health disparities and promoting human-rights protections for gender minorities.

Genetic and environmental influences on individual differences in masculinity, femininity, and gender diagnosticity: analyzing data from a classic twin study.
TLDR
Analyzing data from Loehlin and Nichols's (1976) classic twin study, measures of Masculine Instrumentality, Feminine Expressiveness, and Gender Diagnosticity are computed and it is indicated that additive genetic factors contribute significantly to individual differences in M, F, and GD. Expand

TLDR
Gender diagnosticity measures showed high reliability, predicted sex of S and self-ascribed masculinity and femininity better than contrasted-groups M-F scales, and displayed substantial consistency across domains both within and across the sexes. Expand

TLDR
A new sex-role inventory is described that treats masculinity and femininity as two independent dimensions, thereby making it possible to characterize a person as masculine, feminine, or "androgynous" as a function of the difference between his or her endorsement of masculine and feminine personality characteristics.
