This study quantified changes in self-reported sexual orientation from adolescence to early adulthood, and whether childhood gender nonconformity (GNC) predicted sexual orientation changes. Youth (2,678 boys and 3,359 girls; 96.09% ethnically White) from the Avon Longitudinal Study of Parents and Children (ALSPAC) were included. Self-reported…

The goal of this article was to examine gender-typed behavior longitudinally and to consider its relationship with sexual orientation in adulthood. Data were from 10,624 respondents who completed Wave 1 (adolescence), Wave 3 (emerging adulthood), and Wave 4 (early adulthood) of the National Longitudinal Study of Adolescent to Adult Health. First,…

Childhood gender nonconformity (femininity in males, masculinity in females) predicts a nonstraight (gay, lesbian, or bisexual) sexual orientation in adulthood. In previous work, nonstraight twins reported more childhood gender nonconformity than their genetically identical, but straight, cotwins. However, self-reports could be biased. We…

This study tested the association between multiple prenatal and postnatal early life factors and adolescent sexual orientation in a longitudinal birth cohort. Factors included birth weight, gestational age, parental age at birth, number of older brothers and sisters, breastfeeding, maternal anxiety/depression, family socioeconomic position,…

The experience of minority stress is often named as a cause for mental health disparities among lesbian, gay, and bisexual (LGB) youth, including higher levels of depression and suicidal ideation. The processes or mechanisms through which these disparities occur are understudied. The interpersonal-psychological theory of suicide posits 2 key…

Although recent attention has focused on the likelihood that contemporary sexual minority youth (i.e., gay, lesbian, bisexual [GLB]) are "coming out" at younger ages, few studies have examined whether early sexual orientation identity development is also present in older GLB cohorts. We analyzed retrospective data on the timing of sexual…

Religious faith has been instrumental in fostering positive mental health outcomes for historically disenfranchised populations, such as Black Americans. However, the religious institutional devaluing of same-sex behavior and identity fuels internalized homonegativity (i.e., negative thoughts regarding one's same-sex sexual behavior) for…
