Examining the placement of atypical anorexia nervosa in the eating disorder diagnostic hierarchy relative to bulimia nervosa and binge-eating disorder.

OBJECTIVE: Some individuals meet the criteria for atypical anorexia nervosa and another eating disorder simultaneously. The current study evaluated whether allowing a diagnosis of atypical anorexia nervosa to supersede a diagnosis of bulimia nervosa (BN) or binge-eating disorder (BED) provided additional information on psychological functioning. METHODS: Archival data from 650 university students (87.7% female, 69.4% white) who met Eating Disorder Diagnostic Survey for DSM-5 eating disorder criteria and completed questionnaires assessing quality of life, eating disorder-related impairment, and/or eating pathology at a single time point. Separate regression models used diagnostic category to predict quality of life and impairment. Two diagnostic schemes were used: the DSM-5 diagnostic scheme and an alternative scheme where atypical anorexia nervosa superseded all diagnoses except anorexia nervosa. Model fit was compared using the Davidson-Mackinnon J test. Analyses were pre-registered (https://osf.io/2ejcd). RESULTS: Allowing an atypical anorexia nervosa diagnosis to supersede a BN or BED diagnosis provided better fit to the data for eating disorder-related impairment (p = .02; n = 271), but not physical, psychological, or social quality of life (p's ≥ .33; n = 306). Allowing an atypical anorexia nervosa diagnosis to supersede a BN or BED diagnosis provided a better fit in cross-sectional models predicting purging (p = .02; n = 638), but not body dissatisfaction, binge eating, restricting, or excessive exercise (p's ≥ .08; n's = 633-647). DISCUSSION: The current data support retaining the DSM-5 diagnostic scheme. More longitudinal work is needed to understand the predictive validity of the atypical anorexia nervosa diagnosis. PUBLIC SIGNIFICANCE: The current study examined how changes to the diagnostic categories for eating disorders may change how diagnoses are associated with quality of life and impairment. Overall, findings suggest that the diagnostic hierarchy should be maintained.

Psychosocial correlates of body esteem and disordered eating among sexual minority adolescent girls.

The present study examined whether body esteem mediates the associations between psychosocial factors, including peer victimization and parent-adolescent relationship quality, and multiple categories of disordered eating (DE) within a diverse sample of adolescent sexual minority (SM) girls. Participants were 528 girls, aged 14-18 years, recruited as part of a larger online study on LGBTQ + adolescent health. Participants anonymously completed self-report measures of parent-adolescent relationship quality, sexual orientation-based victimization, body esteem, and DE behaviors, including binge eating, purging, and caloric restriction. Parent-adolescent relationship quality was positively associated with SM adolescent girls' body esteem, and some aspects of body esteem subsequently mediated the associations between parent-adolescent relationship quality and DE behaviors. Experiences of sexual orientation-related victimization were also positively related to endorsement of caloric restriction. However, no significant indirect effects were observed between sexual orientation-related victimization and DE via body esteem. These results suggest parents could influence their SM daughters' DE behaviors via body esteem, and SM girls may be engaging in caloric restriction if they experience victimization, regardless of their body esteem.

Disparities in Childhood Abuse Between Transgender and Cisgender Adolescents.

BACKGROUND AND OBJECTIVES: Transgender adolescents (TGAs) exhibit disproportionate levels of mental health problems compared with cisgender adolescents (CGAs), but psychosocial processes underlying mental health disparities among TGAs remain understudied. We examined self-reported childhood abuse among TGAs compared with CGAs and risk for abuse within subgroups of TGAs in a nationwide sample of US adolescents. METHODS: Adolescents aged 14 to 18 completed a cross-sectional online survey (n = 1836, including 1055 TGAs, 340 heterosexual CGAs, and 433 sexual minority CGAs). Participants reported gender assigned at birth and current gender identity (categorized as the following: cisgender males, cisgender females, transgender males, transgender females, nonbinary adolescents assigned female at birth, nonbinary adolescents assigned male at birth, and questioning gender identity). Lifetime reports of psychological, physical, and sexual abuse were measured. RESULTS: Seventy-three percent of TGAs reported psychological abuse, 39% reported physical abuse, and 19% reported sexual abuse. Compared with heterosexual CGAs, TGAs had higher odds of psychological abuse (odds ratio [OR] = 1.84), physical abuse (OR = 1.61), and sexual abuse (OR = 2.04). Within separate subgroup analyses, transgender males and nonbinary adolescents assigned female at birth had higher odds of reporting psychological abuse than CGAs. CONCLUSIONS: In a nationwide online sample of US adolescents, TGAs had elevated rates of psychological, physical, and sexual abuse compared with heterosexual CGAs. Risk for psychological abuse was highest among TGAs assigned female at birth. In the future, researchers should examine how more frequent experiences of abuse during childhood could contribute to disproportionate mental health problems observed within this population.

Gender Nonconformity and Minority Stress Among Lesbian, Gay, and Bisexual Individuals: A Meta-Analytic Review.

Lesbian, gay, and bisexual (LGB) individuals are less healthy than heterosexual individuals, and minority stress endured by LGB individuals contributes to these health disparities. However, within-groups differences in minority stress experiences among LGB individuals remain underexplored. Individuals are more likely to be categorized as LGB if they exhibit gender nonconformity, so gender nonconformity could influence concealability of sexual orientation among LGB individuals, carrying important implications for the visibility of their stigmatized sexual orientation identity and for how they experience and cope with minority stress. Through a meta-analytic review, we examined how gender nonconformity was associated with minority stress experiences among LGB individuals. Thirty-seven eligible studies were identified and included in analyses. Results indicate gender nonconformity is associated with experiencing more prejudice events, less concealment of sexual orientation, lower internalized homonegativity, and higher expectations of rejection related to sexual orientation among LGB individuals. Gender nonconformity is more strongly associated with experiencing prejudice events among gay and bisexual men than among lesbian and bisexual women. Gender nonconformity is systematically associated with minority stress experiences among LGB individuals, and future research must measure and examine gender nonconformity when investigating the role of minority stress in degraded health outcomes among LGB populations.
