The Survey Measurement of Sexual Orientation: Configurations of Sexual Identity and Attraction and Associations with Mental Health

On the Concordance of Romantic and Sexual Feelings and Identity Among University Students in Taiwan

The degree to which romantic and sexual feelings correspond to one's sexual identity may signify how a person comes to embrace a specific sexual identity. People who endorse an essentialist perspective may expect to see a high degree of concordance between feelings and identity, and a lack of concordance may be associated with negative consequences. People who endorse a social constructionist perspective may view sexual identity as constructed in situ; a lack of concordance is inevitable and may not be associated with negative consequences. This research tests the levels of concordance of feelings and identity by comparing those with and without romantic and sexual feelings using risk ratios and odds ratios. A representative sample of college students in Taiwan was recruited (N = 3882, with 2440 females and 2988 who identified as heterosexual). The findings suggest that (1) people's romantic and sexual feelings largely correspond to their sexual identity, with all risk ratios and odds ratios higher than 1; (2) the concordance was at its lowest level among those with different-sex feelings; (3) gender differences in concordance were trivial; (4) individuals who were questioning their identity were the least clear about what they expect and want in intimate relationships; and (5) no general negative consequences in intimate relationships were observed among discordant/branched individuals. Implications regarding romantic and sexual feelings, sexual identity, and intimate relationships are further discussed.

How a "Something Else" Response Option for Sexual Identity Affects National Survey Estimates of Associations Between Sexual Identity, Reproductive Health, and Substance Use

This randomized experiment tested whether the inclusion of a "something else" response option for a question about sexual identity in a national health survey would significantly moderate estimated differences between sexual identity subgroups in terms of various health outcomes, including substance use and reproductive health. We conducted secondary analyses of data from five consecutive years of the National Survey of Family Growth (NSFG; 2015-2019), where two large national half-samples were randomly assigned to receive one of two different versions of a question about sexual identity (a four-category version that included a "something else" response option or a three-category version omitting this option). We focused on national estimates of differences between subgroups defined by sexual identity. Multivariable models indicated that the estimated subgroup differences changed in a statistically significant fashion when using the four-category version of the sexual identity question for several measures, including 16% of male measures (household size, past-year cigarette use, and past-year illicit drug use) and 15% of female measures (wanting a/another child, ever had a sexually transmitted disease, and past-year marijuana use). The absence of a "something else" response option for questions about sexual identity in national health surveys may cause respondents to select options that do not accurately describe their identities, and this can have a significant effect on national estimates of differences between sexual identity subgroups in terms of selected health outcomes.
