High Burden of Mental Health Problems, Substance Use, Violence, and Related Psychosocial Factors in Transgender, Non-Binary, and Gender Diverse Youth and Young Adults
Transgender and gender diverse (TGD) people are disproportionately impacted by various health issues and associated risk factors, but little is known about differences in these outcomes between gender identities within the TGD population. This study characterized the health of a diverse sample of TGD youth and young adults. Data were taken from the baseline visit of two longitudinal studies in the Chicago area, RADAR ( N  = 1079, M age = 20.8 years) and FAB 400 ( N  = 488, M age = 19.57 years), which are cohorts of young sexual and gender minorities assigned male at birth (AMAB) and assigned female at birth (AFAB), respectively. There was a combined sample of 214 TGD (128 AFAB, 86 AMAB) individuals across cohorts. We examined differences between gender identities in self-reported health and related psychosocial variables, and compared TGD youth and their cisgender sexual minority peers from their cohort of origin on all variables. Among TGD youth, we found high rates of depression and suicidality (ideation, plan, attempt), violence (trauma, victimization, childhood sexual abuse), and substance use (cigarette, alcohol, illicit drug use). With the exception of depression, transgender women and non-binary AMAB youth reported worse health outcomes than transgender men and non-binary AFAB youth. Non-binary AMAB youth reported the highest rates of certain outcomes, including traumatic experiences and suicidal ideation. TGD youth generally reported worse outcomes than cisgender sexual minority youth; these differences were less pronounced among AFAB youth. Findings point to the diversity of experiences within the TGD population and critical needs for intervention approaches to mitigate health disparities.
Substance Use and Relationship Functioning Among Young Male Couples
Research shows that, for different sex couples, individual levels of substance use are deleterious for relationship quality (e.g., satisfaction, intimate partner aggression), whereas dyadic concordance is usually protective. However, there has been no research on these effects among male couples, even though they show increased risk for substance use and certain indices of relationship distress (e.g., intimate partner aggression) compared to different sex couples. Male partners also display distinct similarity patterns and norms surrounding substance use, suggesting that there might be unique effects of substance use on relationship quality among this population. We conducted actor–partner interdependence models of substance use on relationship quality (intimate partner aggression, satisfaction) among a large sample of male dyads ( N  = 934 individuals, N  = 467 dyads). Results suggested that there are novel actor, partner, and similarity effects that imply unique pathways to relationship well-being for male couples. These results are discussed in light of future clinical and empirical efforts. [NCT03186534 – 6/12/2017; NCT03284541 – 6/23/2017].
Can a linking crosswalk table be applied to a different population? An independent validation study for a crosswalk between BSI depression and PROMIS depression scales
A linking procedure establishes a “bridge” between the scores from different patient-reported outcome (PRO) instruments that measure similar constructs. After developing a linking relationship however, it is critical to evaluate whether this relationship can be generalized to different groups. Our study aims to validate a published crosswalk for score conversion between the Brief Symptom Inventory Depression subscale and the Patient-Reported Outcomes Measurement Information System Depression 8a using an independent sample. Data were from a sample of young men who have sex with men (MSM), which differs in terms of participant age, race, and ethnicity from the sample used to develop the existing crosswalk. The validity of the newly derived crosswalk was evaluated in terms of the correlation, mean difference and standard deviation between the observed and the linked scores. The two crosswalks were further compared to evaluate if the difference was within an acceptable range. More than half of the item parameters obtained from the two samples were found to overlap in their confidence intervals. Differences between each pair of scores in the two crosswalks was within three T-score points, well within the range of each crosswalk score’s standard error. This study concludes that an existing crosswalk is replicable on a sample that differs from that used for crosswalk development, but future research should continue to examine the generalizability of the linked parameters and evaluate the reproducibility of this crosswalk to other populations.
High Rate of Discontinuation May Diminish PrEP Coverage Among Young Men Who Have Sex with Men
Understanding pre-exposure prophylaxis (PrEP) discontinuation is key to maximizing its effectiveness at the individual and population levels. Data came from the RADAR cohort study of MSM aged 16–29 years, 2015–2017. Participants included those who reported past 6-month PrEP use and discontinued its use by the interview date. Of the 197 participants who had used PrEP in the past 6 months, 65 discontinued use. Primary reasons for PrEP discontinuation included trouble getting to doctor’s appointments (14, 21.5%) and issues related to insurance coverage or loss (13, 20.0%). Few (21%) who discontinued spoke to their doctor first, which has important implications for future long acting formulations.
Barriers to Gender-Affirming Care for Transgender and Gender Nonconforming Individuals
Gender-affirming care, including hormone therapy, “top” (e.g., chest reconstruction surgery) and “bottom” (e.g., vaginoplasty, phalloplasty, metoidioplasty, etc.) surgeries, and puberty blockers, is an efficacious treatment of gender dysphoria for transgender and gender nonconforming (TGNC) individuals. However, many TGNC people encounter significant barriers in accessing gender-affirming care, which we detail via results from on online study. Participants included 256 TGNC individuals (78.9% White, ages 16–73, Mage = 28.4). Among participants, 61.3% were receiving hormone therapy, 22.7% had undergone top surgery, and 5.5% had undergone bottom surgery. Open-ended responses (n = 201) were thematically analyzed and common barriers included finances and insurance issues, a lack of service availability, and fears or worries. Participants reported various systemic issues and incidents of bias within medical and mental health fields, as well as a lack of medical provider awareness and education. Other themes were interpersonal barriers (e.g., fears of rejection); age and need of parental consent for minors; other medical issues; and a lack of information about how to acquire care. These findings can be utilized to educate professionals in medical and mental health fields about barriers their TGNC patients may encounter in receiving affirming care and suggest a number of ways to improve access to these services.
Protocol for an attention-matched randomized controlled trial of 2GETHER: a relationship education and HIV prevention program for young male couples
Background Young men who have sex with men (YMSM) are disproportionately impacted by the HIV epidemic in the USA, and a large number of new infections among YMSM occur in the context of main or primary partnerships. At the same time, healthy romantic relationships promote health and wellbeing by improving social support and encouraging healthy behaviors. Thus, we created 2GETHER: a relationship education and HIV prevention program for young male couples. 2GETHER is delivered face-to-face in a university setting and is composed of two group sessions and two individualized skills coaching sessions. We observed strong support of the feasibility, acceptability, and preliminary efficacy of 2GETHER in a pilot trial. Methods We are conducting an attention-matched randomized controlled trial (RCT) to test the efficacy of 2GETHER relative to a control condition based on a well-validated positive affect enhancement program. Enrollment occurred between August 2017 and March 2021 in Chicago and surrounding areas, and we enrolled and randomized 128 dyads ( N  = 256 individuals). Follow-up is ongoing and we will examine primary and secondary behavioral outcomes at 12 months post-intervention, with interim follow-up at 3, 6, and 9 months post-intervention. The primary biomedical outcome is sexually transmitted infection incidence at a 12-month follow-up. Discussion 2GETHER is innovative in that it places an equal emphasis on relationship skill building and HIV prevention. Thus, the program has the potential to impact numerous health-related outcomes. Despite challenges related to the recruitment of couples and the COVID-19 pandemic, we were able to enroll a robust sample of young male couples with sufficient power to detect effects on study outcomes. Trial registration ClinicalTrials.gov NCT03186534 .
Validation of the Sexual Orientation Microaggression Inventory in Two Diverse Samples of LGBTQ Youth
Critical race theory asserts that microaggressions, or low-level, covert acts of aggression, are commonplace in the lives of people of color. These theorists also assert a taxonomy of microaggressions, which includes “microassaults,” “microinsults,” and “microinvalidations”. The theory of microaggressions has been adopted by researchers of LGBTQ communities. This study investigated the three-factor taxonomy as it relates to a diverse sample of LGBTQ youth using the newly developed Sexual Orientation Microaggression Inventory (SOMI). Exploratory factor analysis was used to determine the number of factors that exist in SOMI in a sample of 206 LGBTQ-identifying youth. Follow up confirmatory factor analyses were conducted in order to compare single-factor, unrestricted four-factor, second-order, and bi-factor models in a separate sample of 363 young men who have sex with men. The best fitting model was used to predict victimization, depressive symptoms, and depression diagnosis in order to test validity. The best fitting model was a bi-factor model utilizing 19 of the original 26 items with a general factor and four specific factors representing anti-gay attitudes (“microinsults”), denial of homosexuality, heterosexism (“microinvalidations”), and societal disapproval (“microassaults”). Reliability analyses found that the majority of reliable variance was accounted for by the general factor. The general factor was a significant predictor of victimization and depressive symptoms, as well as unrelated to social desirability, suggesting convergent, criterion-related, and discriminant validity. SOMI emerged as a scale with evidence of validity for assessing exposure to microaggressions in a diverse sample of LGBTQ youth.
Methods for the Design and Analysis of Relationship and Partner Effects on Sexual Health
Sexual intercourse involves two people and many aspects of sexual health are influenced by, if not dependent on, interpersonal processes. Yet, the majority of sexual health research involves the study of individuals. The collection and analysis of dyadic data present additional complexities compared to the study of individuals. The aim of this article was to describe methods for the study of dyadic processes related to sexual health. One-sided designs, including the PLM, involve a single individual reporting on the characteristics of multiple romantic or sexual relationships and the associations of these factors with sexual health outcomes are then estimated. This approach has been used to study how relationship factors, such as if the relationship is serious or casual, are associated with engagement in HIV risk behaviors. Such data can be collected cross-sectionally, longitudinally or through the use of diaries. Two-sided designs, including the actor–partner interdependence model, are used when data are obtained from both members of the dyad. The goal of such approaches is to disentangle intra- and inter-personal effects on outcomes (e.g., the ages of an individual and his partner may influence sexual frequency). In distinguishable datasets, there is some variable that allows the analyst to differentiate between partners within dyads, such as HIV status in a serodiscordant couple. When analyzing data from these dyads, effects can be assigned to specific types of partners. In exchangeable dyadic datasets, no variable is present that distinguishes between couple members across all dyads. Extensions of these approaches are described.
Bisexual Men’s Experiences with Discrimination, Internalized Binegativity, and Identity Affirmation: Differences by Partner Gender
Bisexual individuals experience unique forms of discrimination related to their sexual orientation (e.g., anti-bisexual prejudice), which occurs from both heterosexual and gay/lesbian individuals. Bisexual individuals may experience stigma differently depending on the gender of their relationship or sexual partners, because they may be perceived as heterosexual if they have a partner of a different gender and as gay/lesbian if they have a partner of the same gender. The present longitudinal study investigated within-persons differences in anti-bisexual experiences, internalized binegativity, and bisexual identity affirmation based on the gender of participants’ serious relationship partners and gender of sex partners in a sample of 180 young bisexual men. Results indicated that young bisexual men experienced more interpersonal hostility from both heterosexual and gay/lesbian individuals when their serious relationship partner was female. No significant differences were found in other types of anti-bisexual prejudice, internalized binegativity, or bisexual identity affirmation by serious partner gender. For sexual partner gender, men who had only male sex partners experienced more sexual orientation instability attitudes from heterosexual and lesbian/gay individuals; men with only female sex partners experienced more sexual irresponsibility attitudes from heterosexuals, but not from lesbian/gay individuals; and, like those with female serious relationship partners, men with only female sex partners had more frequent experiences of interpersonal hostility from heterosexual and lesbian/gay individuals. Results indicate that bisexual men experience unique forms of prejudice based on the gender of their relationship and sexual partners. Implications for the mental health of bisexual men are discussed.
Moderators of the Relationship Between Internalized Homophobia and Risky Sexual Behavior in Men Who Have Sex with Men: A Meta-Analysis
Research on internalized homophobia (IH) has consistently linked it to both mental and physical health outcomes, while research on its relationships with other variables has been inconsistent. Some research and theory support the association between IH and risky sexual behavior, but much of this research has been plagued by methodological issues, varying measures, and has produced inconsistent findings. Coming to a better understanding of the utility of IH as a potential mechanism or predictor of risky sex in men who have sex with men (MSM) may help to inform future studies of HIV risk in this population as well as the development of prevention interventions. The current study used hierarchical linear modeling to perform meta-analysis combining effect sizes across multiple studies of the relationships between IH and risky sexual behavior. Additionally, the use of multilevel modeling techniques allowed for the evaluation of the moderating effects of age, year of data collection, and publication type on this relationship. Sixteen studies were meta-analyzed for the relationship between IH and risky sexual behavior ( N  = 2,837), revealing a small overall effect size for this relationship. However, a significant moderating effect was found for the year of data collection, such that the correlation between these two variables has decreased over time. The current utility of this construct for understanding sexual risk taking of MSM is called into question.
