Scant research exists on the development of mostly heterosexual identity, the largest sexual orientation minority subgroup. We used longitudinal latent class analysis to characterize the patterns of identification with lesbian, gay, bisexual (LGB), or mostly heterosexual identities from ages 12 to 23 in 13,859 youth (57% female) in a U.S. national cohort. Three classes emerged: completely heterosexual (88.2%), mostly heterosexual (9.5%), and LGB (2.4%). LGB class youth generally identified with sexual minority identities by ages 12-17. In contrast, mostly heterosexual class youth identified with sexual minority identities gradually, with steady increases in endorsement starting at the age of 14. Developmental implications of these differential patterns are discussed.
关于大多数异性恋身份的发展，这一最大的性取向少数群体亚组的研究甚少。我们使用纵向潜在类别分析，对来自美国全国队列的 13859 名青年（57%为女性）在 12 至 23 岁时对同性恋、双性恋（LGB）或大多数异性恋身份的认同模式进行了描述。有三个类别出现：完全异性恋（88.2%）、大多数异性恋（9.5%）和 LGB（2.4%）。LGB 类别青年通常在 12-17 岁时认同性少数群体身份。相比之下，大多数异性恋类别青年逐渐认同性少数群体身份，从 14 岁开始，对其认同的支持率稳步上升。讨论了这些不同模式的发展意义。
