Sexual Orientation Change among Adolescents and Young Adults: A Systematic Review

Knowledge gaps in existing research exploring sexual fluidity and mental health among young adults

While there is a large body of evidence indicating that sexual minority youth experience inequitably high rates of mental health problems (eg, depression, suicidality), we know little about how temporal changes in sexual attractions, identities and behaviour may impact mental health (and other) outcomes. In this essay, we review existing research regarding sexual fluidity and mental health among young adults in order to identify critical knowledge gaps with respect to an epidemiological understanding of the relationship between these factors. We describe three gaps that in turn inform a larger public health research agenda on this topic. First, there are a number of methodological challenges given that fluidity can occur over short or long periods of time and across multiple dimensions of sexual orientation (eg, attractions, identities and behaviour) with various patterns (eg, directionality of change). Tailored measures that accurately and inclusively reflect diversities of sexual fluidity trajectories are needed. Second, causal relationships between sexual fluidity and mental health remain uncertain and unquantified. Third, little is known about how features of context (eg, gender norms and political climate) influence youth experiences with sexual fluidity and mental health. Finally, we propose a set of recommendations to address these knowledge gaps to improve the quality of epidemiological research involving young people.

Sexual Orientation Identity Change, Developmental Trajectories of Depressive Symptoms, and Childhood Abuse From Adolescence to Young Adulthood

PURPOSE

This study tested differences between youths who reported being heterosexual at ages 15.5 and 21, and those who changed from reporting being heterosexual at age 15.5 to nonheterosexual at age 21, in the developmental trajectories of depressive symptoms from age 22-24 years, and whether these longitudinal patterns were explained by childhood and adolescent abuse.

METHODS

The Avon Longitudinal Study of Parents and Children (ALSPAC) was used (849 male youths and 1,455 female youths). Youths' self-reported sexual orientation was measured at ages 15.5 and 21, and depressive symptoms were measured at ages 22, 23, and 24. Childhood and adolescent abuse between birth and 17 years were reported by youths and their mothers.

RESULTS

Male and female youths who changed from reporting being heterosexual to nonheterosexual reported significantly more depressive symptoms than their consistently heterosexual counterparts at all 3 ages (except the association for male youths at age 24), with total effects (unstandardized regression coefficients) ranging from 2.00 to 5.27. These associations were weakened but remained statistically significant when childhood and adolescent abuse was controlled for, with direct effects ranging from 1.50 to 4.68. These associations were mediated through childhood and adolescent abuse, with indirect effects ranging from 0.48 to 0.58. Differences between youths who consistently reported being heterosexual and those who changed from reporting being heterosexual to nonheterosexual in depressive symptoms decreased from age 22-24 years, possibly due to the success of identity integration.

DISCUSSION

Childhood and adolescent abuse may partially explain these developmental disparities.

Sexual Identity Fluidity and Depressive Symptoms: Findings From a National Longitudinal Study of Sexual Minority Adolescents

PURPOSE

Sexual minority adolescents (SMAs) consistently report elevated risk of mental health symptoms, including depression. Sexual identities may change over time (referred as sexual identity fluidity), particularly during adolescence. This study examined the effect of sexual identity fluidity on depressive symptoms over time.

METHODS

National longitudinal data were analyzed from SMAs aged 14-17 years (N = 1,077) in the adolescent stress experiences over time study during an 18-month period. Multigroup time-varying covariate latent growth models were employed to examine the effect of sexual identity fluidity on depressive symptoms.

RESULTS

In the sample, 40% of SMAs reported at least 1 change in sexual identity during an 18-month period. Cisgender females reported sexual identity fluidity at a higher rate than their male counterparts (46.9% vs. 26.6%, respectively). In our first model (total sample), a change in sexual identity was associated with reporting fewer depressive symptoms (b = -0.591, p = .004). In our multigroup model (by sex assigned at birth), a change in sexual identity was significantly associated with reporting fewer depressive symptoms among cisgender females (b = -0.591, p < .01). However, there was no significant effect found among cisgender males. The models controlled for age and race or ethnicity.

DISCUSSION

The results add to the limited knowledge on the complex relationship between sexual identity fluidity and mental health risks over time among adolescents. Our results indicate that sexual identity development and change processes differ between cisgender females and males. The nuances associated with these sexual identity processes need further investigation.

Is everyone a mix of straight and gay? A social pressure theory of sexual orientation, with supporting data from a large global sample

Sigmund Freud, Alfred Kinsey, E.O. Wilson, and others have suggested that social pressure suppresses natural tendencies for humans to express bisexuality, the apparent norm for one of our two closest genetic relatives, the bonobo. An analysis of data obtained from a new online sample of 1,150,938 people in 215 countries and territories (63.9% from the United States, United Kingdom, and Canada) who completed the English version of a validated questionnaire of sexual orientation lends support to this idea. A histogram of scores from 0 (exclusive opposite-sex inclinations) to 18 (exclusive same-sex inclinations) forms a near-normal distribution. Although this distribution was likely caused to some extent by sampling bias, it may also reflect the unusual honesty people show when taking online tests anonymously, as an increasing body of evidence demonstrates. We present a formal mathematical expression of a social pressure theory of sexual orientation, along with empirical evidence and computational explorations that support the theory. We also present an analysis of the new data set. Among other findings: sexual orientation labels corresponded to broad, skewed, overlapping distributions of scores. Self-labeled gays/lesbians and, to a greater extent, self-labeled straights, reported that the larger the mismatch between their sexual orientation label and their actual sexual inclinations, the more distress they felt regarding their sexual orientation, a finding that is predictable from cognitive dissonance theory. Educating the public about the true nature of sexual orientation might quell the often rancorous public debates on this topic, as well as give comfort to a large number of mislabeled people.

Sexual identity fluidity, identity management stress, and depression among sexual minority adolescents

Introduction

Sexual identity is mutable and evolving, particularly during adolescence. Sexual identity fluidity could be stressful for some adolescents and may differ by birth-sex. Evidence suggests chronic stress can lead to negative mental health outcomes. However, it is unknown if these two processes (stress and depression) differ by sexual identity fluidity.

Methods

This paper studied time-sequential associations between identity management stress and depression over time by sexual identity fluidity, in a national longitudinal data from sexual minority adolescents (SMA) aged 14-17 years using a multigroup autoregressive cross-lagged model (n = 1077).

Results

In the sample, 40% of SMA reported at least one change in sexual identity over 18-month period. Greater number of cisgender females reported sexual identity fluidity compared to their male counterparts (46.9% vs. 26.6%). A temporal cross-lagged effect was reported between depression and identity management stress among cisgender females who reported fluidity in sexual identity; and no cross-lagged effect was reported among those females who did not report fluidity. However, among cisgender male sample depression predicted subsequent identity management stress, irrespective of their change sexual identity fluidity status.

Conclusion

Public health programs and practice must be responsive to the sexual identity fluidity processes among adolescents, with particular attention to minority stress and depression. In addition, our results indicate that sexual identity development and fluidity processes differ between cisgender females and males; and the nuances associated with these processes of change need further investigation.
