Two-Question Method of Assessing Gender Identity (2QAGI)

Facets of Gender Assessed: (a) birth-assigned category and (b) self-assigned identity

Reference: Tate, C. C., Ledbetter, J. N., & Youssef, C. P. (2013). A two-question method for assessing gender categories in the social and medical sciences. Journal of Sex Research, 50, 767-776. [view .pdf]

The 2QAGI is a demographic tool that is meant to replace the single-question assessment of gender as: What is your gender? or What is your sex?, which commonly has two response options: Male, Female. (The 2QAGI also replaces the single-question method with four response options: Male, Female, Transgender, and Other.)

In contrast to the single-question methods, the 2QAGI asks about current gender identity and birth-assigned category in two separate questions: (a) What is your current gender identity? and What gender category were you assigned at birth?

Response options are particular to the questions. For the current identity question, 2QAGI response options are: Female, Male, Trans Female, Trans Male, Genderqueer and Intersex. For the birth-assigned question, 2QAGI response options are: Female, Male, and Intersex.

Importantly, the full 2QAGI allows for branching for participants who indicate current identity as trans female, trans male, genderqueer or intersex. (Collectively, these identities are referred to as "transgender spectrum" or "trans spectrum" or "trans*".) Also, for those who indicate intersex as a birth-assigned category, there is a branch to a question about gender raised at birth.

Statistical Properties of the 2QAGI:

The 2QAGI captures up to 3 times as much data concerning transgender and genderqueer participants as compared to a single-question method with transgender and other as response options. (See Tate et al., 2012, Table 1, p. 771.)

The 2QAGI has a near zero (i.e., 0.16%) missing data rate across 752 respondents. (For comparison, the missing data rate for a single-question method is as low as 1.26% [across 238 respondents, using four response options].) Thus, existing methods lose gender self-categorization data at a rate more than 7 times higher than the 2QAGI.

Versions of the 2QAGI (adjectives and nouns)

2QAGI adjectives version asks participants to describe their current identities (e.g., as female or male); 2QAGI nouns version asks participants to state their current identities as a noun (e.g., as woman or man). (The adjectives version was used to collect data in the Tate et al. (2013) article.) Both versions are available as either hardcopy format or online format in the next two sections. No permission is required to use the 2QAGI versions; they are free to all researchers.
