A Test of the Behavioral Model of Tic Disorders Using a Dynamical Systems Framework.

Tic disorders are a class of neurodevelopmental disorders characterized by involuntary motor and/or vocal tics. It has been hypothesized that tics function to reduce aversive premonitory urges (i.e., negative reinforcement) and that suppression-based behavioral interventions such as habit reversal training (HRT) and exposure and response prevention (ERP) disrupt this process and facilitate urge reduction through habituation. However, previous findings regarding the negative reinforcement hypothesis and the effect of suppression on the urge-tic relationship have been inconsistent. The present study applied a dynamical systems framework and within-subject time-series autoregressive models to examine the temporal dynamics of urges and tics and assess whether their relationship changes over time. Eleven adults with tic disorders provided continuous urge ratings during separate conditions in which they were instructed to tic freely or to suppress tics. During the free-to-tic conditions, there was considerable heterogeneity across participants in whether and how the urge-tic relationship followed a pattern consistent with the automatic negative reinforcement hypothesis. Further, little evidence for within-session habituation was seen; tic suppression did not result in a reduction in premonitory urges for most participants. Analysis of broader urge change metrics did show significant disruption to the urge pattern during suppression, which has implications for the current biobehavioral model of tics.

Interest in over-the-counter progestin-only pills among transgender, nonbinary, and gender-expansive individuals in the United States.

BACKGROUND: In July 2023, the US Food and Drug Administration approved the first nonprescription oral contraceptive, a progestin-only pill, in the United States. Transgender, nonbinary, and gender-expansive people assigned female or intersex at birth face substantial contraceptive access barriers and may benefit from over-the-counter oral contraceptive access. However, no previous research has explored their perspectives on this topic. OBJECTIVE: This study aimed to measure interest in over-the-counter progestin-only pill use among transgender, nonbinary, and gender-expansive individuals assigned female or intersex at birth. STUDY DESIGN: We conducted an online, cross-sectional survey from May to September 2019 (before the US Food and Drug Administration approval of a progestin-only pill) among a convenience sample of transgender, nonbinary, and gender-expansive people assigned female or intersex at birth who were aged 18 to 49 years from across the United States. Using descriptive statistics and logistic regression analyses, we estimated interest in over-the-counter progestin-only pill use (our outcome) overall and by sociodemographic and reproductive health characteristics (our exposures). We evaluated separate logistic regression models for each exposure. In each model, we included the minimally sufficient adjustment set to control for confounding pathways between the exposure and outcome. For the model for age, we ran a univariable logistic regression model; for all other exposures, we ran multivariable logistic regression models. RESULTS: Among 1415 participants in our sample (median age, 26 years), 45.0% (636/1415; 95% confidence interval, 42.3-47.6) were interested in over-the-counter progestin-only pill use. In separate logistic regression models for each exposure, there were higher odds of interest among participants who were aged 18 to 24 years (odds ratio, 1.67; 95% confidence interval, 1.33-2.10; vs those aged 25-34 years), those who were uninsured (adjusted odds ratio, 1.91; 95% confidence interval, 1.24-2.93; vs insured), those who currently used oral contraceptives (adjusted odds ratio, 1.69; 95% confidence interval, 1.17-2.44; vs non-users), had ≤high school degree (adjusted odds ratio, 3.02; 95% confidence interval, 1.94-4.71; vs college degree), had ever used progestin-only pills (adjusted odds ratio, 2.32; 95% confidence interval, 1.70-3.17; vs never users), and who wanted to avoid estrogen generally (adjusted odds ratio, 1.32; 95% confidence interval, 1.04-1.67; vs those who did not want to avoid estrogen generally) or specifically because they viewed it as a feminizing hormone (adjusted odds ratio, 1.72; 95% confidence interval, 1.36-2.19; vs those who did not want to avoid estrogen because they viewed it as a feminizing hormone). There were lower odds of interest among participants with a graduate or professional degree (adjusted odds ratio, 0.70; 95% confidence interval, 0.51-0.96; vs college degree), those who were sterilized (adjusted odds ratio, 0.31; 95% confidence interval, 0.12-0.79; vs not sterilized), and those who had ever used testosterone for gender affirmation (adjusted odds ratio, 0.72; 95% confidence interval, 0.57-0.90; vs never users). CONCLUSION: Transgender, nonbinary, and gender-expansive individuals were interested in over-the-counter progestin-only pill use, and its availability has the potential to improve contraceptive access for this population.

Long-term follow-up of acceptance-enhanced behavior therapy for trichotillomania.

Acceptance-enhanced behavior therapy for trichotillomania (AEBT-TTM) is effective in reducing trichotillomania (TTM) symptoms, but the durability of treatment effects remains in question. This study analyzed 6-month follow-up data from a large randomized clinical trial comparing AEBT-TTM to an active psychoeducation and supportive therapy control (PST). Adults with TTM (N=85; 92% women) received 10 sessions of AEBT-TTM or PST across 12 weeks. Independent evaluators assessed participants at baseline, post-treatment, and 6 months follow-up. For both AEBT-TTM and PST, self-reported and evaluator-rated TTM symptom severity decreased from baseline to follow-up. TTM symptoms did not worsen from post-treatment to follow-up. At follow-up, AEBT-TTM and PST did not differ in rates of treatment response, TTM diagnosis, or symptom severity. High baseline TTM symptom severity was a stronger predictor of high follow-up severity for PST than for AEBT-TTM, suggesting AEBT-TTM may be a better option for more severe TTM. Results support the efficacy of AEBT-TTM and show that treatment gains were maintained over time. Although AEBT-TTM yielded lower symptoms at post-treatment, 6-month follow-up outcomes suggest AEBT-TTM and PST may lead to similar symptom levels in the longer term. Future research should examine mechanisms that contribute to long-term gain maintenance.

Substance Use Over Time Among Sexual and Gender Minority People: Differences at the Intersection of Sex and Gender.

Purpose: Sexual and gender minority (SGM) people are at greater risk for substance use than heterosexual and cisgender people, but most prior work is limited by cross-sectional analyses or the examination of single substance use. This study examined substance use over time among SGM people to identify patterns of polysubstance use at the intersection of sex and gender. Methods: Data were collected annually over 4 years from SGM respondents (n = 11,822) in The Population Research in Identity and Disparities for Equality (PRIDE) Study. Differences in substance use patterns (any prior 30-day use of 15 substances) by gender subgroup were examined with latent class analysis, and multinomial regression models tested relationships between gender subgroup and substance use. Results: Eight classes of substance use were observed. The three most common patterns were low substance use (49%), heavy episodic alcohol use (≥5 alcoholic drinks on one occasion) with some cannabis and tobacco use (14%), and cannabis use with some tobacco and declining heavy episodic alcohol use (13%). Differences observed included lower odds of patterns defined by heavy episodic alcohol use with some cannabis and tobacco use in all gender subgroups relative to cisgender men and persons with low substance use (odds ratios [ORs] 0.26-0.60). Gender expansive people assigned female at birth, gender expansive people assigned male at birth, and transgender men had greater odds of reporting cannabis use with small percentages of heavy episodic alcohol and tobacco use (ORs: 1.41-1.60). Conclusion: This study suggests that there are unique patterns of polysubstance use over time among gender subgroups of SGM people.

Family building and pregnancy experiences of cisgender sexual minority women.

BACKGROUND: Although 10% to 20% of cisgender women aged 18 to 40 years have a sexual minority identity (eg, bisexual, lesbian, and queer), there is limited research on the family building and pregnancy experiences of sexual minority cisgender women. Improving our understanding of the family building and pregnancy experiences of cisgender sexual minority women is critical for improving the perinatal health of this population. OBJECTIVE: This study aimed to compare the mode of family building, past pregnancy experiences, and future pregnancy intentions among cisgender sexual minority women by sexual orientation. STUDY DESIGN: This is an observational study which was conducted using cross-sectional data collected in 2019 from a national sample of 1369 cisgender sexual minority women aged 18 to 45 years. RESULTS: Most participants (n=794, 58%) endorsed multiple sexual orientations, most commonly queer (n=641, 47%), lesbian (n=640, 47%), and/or bisexual (n=583, 43%). There were 243 (18%) cisgender sexual minority women who were parents. Pregnancy was used by 74% (181/243) of women to build their families. Among participants who used pregnancy, 60% (108/181) became pregnant through sexual activity with another parent of the child, whereas 27% (64/243) of women used donor sperm. An additional 10% (n=24) became parents through second-parent adoption, 10% (n=25) through adoption, and 14% (n=35) through step-parenting. Bisexual women more often used sexual activity to become parents (61/100, 61%) compared with queer (40/89, 45%) and lesbian women (40/130, 31%). In contrast, lesbian (50/130, 39%) and queer (25/89, 27%) women more often used donor sperm to become parents compared with bisexual women (11/100, 11%). Among the 266 (19%) cisgender sexual minority women who had ever been pregnant, there were 545 pregnancies (mean, 2.05 pregnancies per woman). Among those pregnancies, 59% (n=327) resulted in live birth, 23% (n=126) resulted in miscarriage, 15% (n=83) resulted in abortion, and 2% (n=9) resulted in ectopic pregnancy. A quarter of women had future pregnancy intentions, with no differences by sexual orientation. Overall, few participants (16%) reported that all of their healthcare providers were aware of their sexual orientation. CONCLUSION: Cisgender sexual minority women primarily built their families through pregnancy and a quarter have future pregnancy desires. In addition, there were important differences in family building methods used by sexual orientation. Providers should be aware of the pregnancy and family-building patterns, plans, and needs of cisgender sexual minority women.

Active Social Media Use and Health Indicators Among Sexual and Gender Minority Adults.

Purpose: Sexual and gender minority (SGM) individuals may receive social support through active use of social media (i.e., posting and interacting). This study examined associations between active social media use, social support, and health indicators in a large sample of SGM adults in the United States. Methods: Data were derived from the 2017 wave of The PRIDE Study, a national cohort study of SGM health. SGM-identified adults reporting social media use (N = 5995) completed measures of active social media use, social support, depressive symptoms, cigarette smoking, hazardous drinking, sleep, and physical activity. Regression models examined main and interactive effects of active social media use and social support on health indicators. Results: The sample reported a moderate level of active social media use (mean [M] = 3.2 [1.0], scale = 1-5) and relatively high social support (M = 16.7 [3.3], scale = 4-20); 31.8% reported moderate-to-severe depressive symptoms. Participants with greater active social media use were more likely to experience depressive symptoms (adjusted odds ratio [AOR] = 1.18, 95% confidence interval [CI] = 1.10-1.26), cigarette smoking (AOR = 1.11, 95% CI = 1.01-1.22), insufficient sleep (AOR = 1.13, 95% CI = 1.06-1.21), and physical inactivity (AOR = 1.09, 95% CI = 1.02-1.15) than those with less active social media use. Active social media use did not significantly interact with social support to predict any health indicators (p values >0.159). Conclusions: Among SGM adults, active social media use was associated with several negative health indicators. Active social media use may increase health risks, or SGM adults with poor health may actively use social media to maintain social connections. Moderate active social media use may be compatible with health.

Investigating the factor structure and measurement invariance of the eating disorder examination questionnaire (EDE-Q) among cisgender gay men and lesbian women from the United States.

BACKGROUND: Although the Eating Disorder Examination-Questionnaire (EDE-Q) is one of the most widely used self-report assessments of eating disorder symptoms, evidence indicates potential limitations with its original factor structure and associated psychometric properties in a variety of populations, including sexual minority populations. The aims of the current investigation were to explore several previously published EDE-Q factor structures and to examine internal consistency and measurement invariance of the best-fitting EDE-Q model in a large community sample of cisgender gay men and cisgender lesbian women. METHODS: Data were drawn from 1624 adults (1060 cisgender gay men, 564 cisgender lesbian women) who participated in The PRIDE Study, a large-scale longitudinal cohort study of sexual and gender minorities from the United States. A series of confirmatory factor analyses (CFAs) were conducted to explore the fit of eight proposed EDE-Q models; internal consistency (Cronbach's alphas, Omega coefficients) and measurement invariance (multi-group CFA) were subsequently evaluated. RESULTS: A brief seven-item, three-factor (dietary restraint, shape/weight overvaluation, body dissatisfaction) model of the EDE-Q from Grilo et al. (Obes Surg. 23:657-662, 2013), consistently evidenced the best fit across cisgender gay men and lesbian women. The internal consistencies of the three subscales were adequate in both groups, and measurement invariance across the groups was supported. CONCLUSIONS: Taken together, these findings support the use of the seven-item, three-factor version of the EDE-Q for assessing eating disorder symptomatology in cisgender gay men and lesbian women. Future studies can confirm the current findings in focused examinations of the seven-item, three-factor EDE-Q in diverse sexual minority samples across race, ethnicity, socioeconomic status, and age ranges.

We asked cisgender gay men and lesbian women in The PRIDE Study to fill out a widely used survey about eating disorders, the Eating Disorder Examination-Questionnaire. We found that a version of this questionnaire based on seven questions including three parts­(1) dietary restraint, (2) shape and weight overvaluation, and (3) body dissatisfaction­had the best fit. These findings can assist doctors and scientists in understanding eating disorders in cisgender gay men and lesbian women.

Evaluating the feasibility, acceptability, and preliminary effectiveness of tele-comprehensive behavior therapy for tics (teleCBIT) for Tourette syndrome in youth and adults.

INTRODUCTION: Comprehensive behavioral intervention for tics (CBIT) is an efficacious, first-line treatment for Tourette syndrome (TS) and other chronic or persistent tic disorders. However, CBIT's public health impact has been limited by suboptimal treatment access. Preliminary research has shown that providing CBIT over videoconference (teleCBIT) is a promising delivery method for patients who cannot access in-person care. However, extant studies have been small efficacy trials focused only on pediatric patients. Replication of these studies is needed in additional treatment settings and across a wider age range of patients, especially in light of advances in telehealth technology and increasing telehealth adoption among practitioners. METHODS: We conducted a single-arm trial to evaluate the feasibility, acceptability, and effectiveness of teleCBIT embedded in comprehensive, medical tic specialty clinics. From October 2016 to September 2018, patients were offered teleCBIT at their usual care appointments. Those who were interested and met inclusion/exclusion criteria received 8 sessions of CBIT guided by a manualized protocol. An independent evaluator, masked to treatment progress, administered assessments at baseline, post-treatment, and 3 and 6 months after treatment. RESULTS: Twenty-five percent of patients who were offered treatment initiated teleCBIT through the study, and all treatment initiators completed treatment. From pre- to post-treatment, decreases in Yale Global Tic Severity Scale (YGTSS) total tic severity scores showed a large effect size among pediatric patients (n = 19; t = 5.72, P < 0.001, d = 1.31) and a medium-to-large effect size for adult patients (n = 10, t = 1.41, P = 0.096, d = 0.664). Thirteen of 19 pediatric patients (68%) and 6 of 10 adult patients (60%) had a positive global treatment response at post-treatment. Patients rated the treatment as highly satisfactory. Ninety-three percent of sessions were free of substantial technical problems. DISCUSSION: Within the context of medical tic specialty clinics, teleCBIT demonstrated strong evidence of feasibility, acceptability, and preliminary effectiveness comparable to in-person treatment for both pediatric and adult patients. TeleCBIT warrants study in future research on enhancing care systems for patients with TS. TRIAL REGISTRY: https://clinicaltrials.gov/ct2/keydates/NCT04007913.

Reports of Negative Interactions with Healthcare Providers among Transgender, Nonbinary, and Gender-Expansive People assigned Female at Birth in the United States: Results from an Online, Cross-Sectional Survey.

Over one million people in the United States are transgender, nonbinary, or gender expansive (TGE). TGE individuals, particularly those who have pursued gender-affirming care, often need to disclose their identities in the process of seeking healthcare. Unfortunately, TGE individuals often report negative experiences with healthcare providers (HCPs). We conducted a cross-sectional online survey of 1684 TGE people assigned female or intersex at birth in the United States to evaluate the quality of their healthcare experiences. Most respondents (70.1%, n = 1180) reported at least one negative interaction with an HCP in the past year, ranging from an unsolicited harmful opinion about gender identity to physical attacks and abuse. In an adjusted logistic regression model, those who had pursued gender-affirming medical care (51.9% of the sample, n = 874) had 8.1 times the odds (95% CI: 4.1-17.1) of reporting any negative interaction with an HCP in the past year, compared to those who had not pursued gender-affirming care, and tended to report a higher number of such negative interactions. These findings suggest that HCPs are failing to create safe, high-quality care interactions for TGE populations. Improving care quality and reducing bias is crucial for improving the health and well-being of TGE people.

Investigating the factor structure and measurement invariance of the Eating Disorder Examination-Questionnaire (EDE-Q) in a community sample of gender minority adults from the United States.

OBJECTIVE: The Eating Disorder Examination-Questionnaire (EDE-Q) is one of the most widely used self-report assessments of eating disorder symptoms. However, evidence indicates potential problems with its original factor structure and associated psychometric properties in a variety of populations, including gender minority populations. The aim of the current investigation was to explore several previously published EDE-Q factor structures and to examine internal consistency and measurement invariance of the best-fitting EDE-Q model in a large community sample of gender minority adults. METHODS: Data were drawn from 1567 adults (337 transgender men, 180 transgender women, and 1050 gender-expansive individuals) who participated in The PRIDE Study, a large-scale longitudinal cohort study of sexual and gender minorities from the United States. A series of confirmatory factor analyses (CFAs) were conducted to explore the fit of eight proposed EDE-Q models; internal consistency (Cronbach's alphas, Omega coefficients) and measurement invariance (multi-group CFA) were subsequently evaluated. RESULTS: A brief seven-item, three-factor (dietary restraint, shape/weight overvaluation, body dissatisfaction) model of the EDE-Q consistently evidenced the best fit across gender minority groups (transgender men, transgender women, gender-expansive individuals). The internal consistencies of the three subscales were adequate in all groups, and measurement invariance across the groups was supported. DISCUSSION: Taken together, these findings support the use of the seven-item, three-factor version of the EDE-Q for assessing eating disorder symptomatology in gender minority populations. Future studies can confirm the current findings in focused examinations of the seven-item, three-factor EDE-Q in diverse gender minority samples across race, ethnicity, socioeconomic status, and age ranges. PUBLIC SIGNIFICANCE STATEMENT: Although transgender individuals have greater risk of developing an eating disorder, the factor structure of the Eating Disorder Examination-Questionnaire, one of the most widely used eating disorder assessment measures, has not been explored in transgender adults. We found that a seven-item model including three factors of dietary restraint, shape and weight overvaluation, and body dissatisfaction had the best fit among transgender and nonbinary adults.

Our pride, our joy: An intersectional constructivist grounded theory analysis of resources that promote resilience in SGM communities.

INTRODUCTION: Sexual and gender minority (SGM) communities, including lesbian, gay, bisexual, transgender, queer, intersex, asexual, and Two-Spirit people, have historically been researched from a deficits-based approach that fails to highlight the ways communities survive and thrive in the face of adversity. This study endeavored to create a model of resources that promote SGM resilience using a sample that amplified traditionally underrepresented perspectives, including individuals from racial and/or ethnic minority groups, trans and/or gender diverse individuals, individuals on the asexual spectrum, and older adults. METHODS: Participant responses to three open-ended questions from The PRIDE Study's (an online national longitudinal cohort study of SGM people) 2018 Annual Questionnaire were analyzed using constructivist grounded theory. These questions examined what brings people joy and what they appreciate most about their SGM identity. Participants (n = 315) were randomly selected from a larger sample of people who had responded to demographic questions and at least one open-ended question (N = 4,030) in a manner to ensure diverse representation across race/ethnicity, gender identity, sexual orientation, age, and region of residence. RESULTS: The proposed model includes social resources (Connecting with Others, Cultivating Family, Helping Others, Participating in Culture and Spirituality), affective generative resources (Engaging in Enriching Pursuits, Accessing Economic Resources), and introspective resources (Exploring One's Authentic Self, Persevering through Hardship) that are theorized to contribute to SGM resilience across the life course. CONCLUSIONS: SGM communities may tap into various resources to promote resilience. As public health practitioners, we can help to foster this resilience by resourcing and supporting initiatives that foster social connection, create spaces for community members to engage with various types of enrichment, facilitate access to economic resources, and provide support and inclusion for all SGM community members.

Healthcare Mistreatment, State-Level Policy Protections, and Healthcare Avoidance Among Gender Minority People.

Introduction: This study examined whether past experiences of mistreatment in healthcare were associated with greater healthcare avoidance due to anticipated mistreatment among gender minority (GM) people. We evaluated whether state-level healthcare policy protections moderated this relationship. Methods: Data from the 2018 Annual Questionnaire of The PRIDE Study, a national longitudinal study on sexual and gender minority people's health, were used in these analyses. Logistic regression modeling tested relationships between lifetime healthcare mistreatment due to gender identity or expression and past-year healthcare avoidance due to anticipated mistreatment among GM participants. Interactions between lifetime healthcare mistreatment and state-level healthcare policy protections and their relationship with past-year healthcare avoidance were tested. Results: Participants reporting any lifetime healthcare mistreatment had greater odds of past-year healthcare avoidance due to anticipated mistreatment among gender expansive people (n = 1290, OR = 4.71 [CI]: 3.57-6.20), transfeminine people (n = 263, OR = 10.32 [CI]: 4.72-22.59), and transmasculine people (n = 471, OR = 3.90 [CI]: 2.50-6.13). Presence of state-level healthcare policy protections did not moderate this relationship in any study groups. Conclusions: For GM people, reporting lifetime healthcare mistreatment was associated with healthcare avoidance due to anticipated mistreatment. State-level healthcare policy protections were not a moderating factor in this relationship. Efforts to evaluate the implementation and enforcement of state-level policies are needed. Continued efforts to understand instances of and to diminish healthcare mistreatment of GM people are recommended.

Disordered Eating and Body Dissatisfaction in Transgender and Gender-Expansive Adults: An Evaluation and Integration of the Gender Minority Stress and Resilience and Tripartite Influence Models.

Transgender and gender-expansive (TGE) people, including transgender and nonbinary individuals, experience elevated rates of body dissatisfaction and disordered eating compared to cisgender individuals, but little is known about why. To address this research gap, we compared the ability of TGE-specific factors as proposed in the gender minority stress and resilience (GMSR) model, general psychological factors contained in the tripartite influence (TI) model, and an integration of these frameworks to explain body dissatisfaction and disordered eating among TGE individuals. Regression analyses were conducted to test the models' abilities to explain experiences reported in a survey of 93 U.S. TGE adults, including 43 transgender women respondents (46.2%) and 31 transgender men respondents (33.3%). Participants were diverse with regard to age (M = 34.19, SD = 12.02) and ethnoracial background (e.g., 29.0% Hispanic/Latinx, 17.2% Black/African American, 6.5% American Indian/Alaska Native; 5.4% multiracial). Results demonstrated both models' abilities to explain body dissatisfaction and disordered eating independently, except for the relationship between body dissatisfaction and the thinness-oriented TI model. An integration of the models better explained body dissatisfaction and disordered eating compared to either model alone. Notably, some findings did not align with the two frameworks, suggesting existing models may not adequately describe pathways through which disordered eating emerges in TGE populations. Specifically, body dissatisfaction showed no significant relationship with disordered eating and was not well explained by the TI model, and higher gender identity pride was related to greater disordered eating symptoms. Implications for clinical care and future research are discussed.

State-Level Policy Environments, Discrimination, and Victimization among Sexual and Gender Minority People.

Legislation has been passed in some states to reduce discrimination and victimization toward sexual and gender minority people (SGM; people who are not solely heterosexual and/or whose gender identity is not equal to what is socially associated with sex assigned at birth). The purpose of these analyses is to test whether state-level policy environments are associated with past-year discrimination and victimization among SGM people. Cross-sectional data from The Population Research in Identity and Disparities for Equality (PRIDE) Study annual questionnaire (collected 2018−2019), a national study of the health of SGM adults in the USA, were used for these analyses. Measures included related to discrimination, victimization, and demographic characteristics. State-level policy environments were measured using data from the Movement Advancement Project. Logistic regression analyses evaluated state-level policy environment scores and past-year discrimination and victimization among gender identity categories. In this sample, 7044 people (gender minority n = 2530) were included. Cisgender sexual minority (odds ratio [OR] = 1.007, p = 0.041) and the gender expansive subgroup of gender minority people (OR = 1.010, p = 0.047) in states with more protective policy environments had greater odds of discrimination. The gender expansive subgroup was found to have greater odds of victimization in states with more protective policy environments (OR = 1.003, p < 0.05). There was no relationship between state-level policy environments and victimization among any other study groups. SGM people may experience increased risk for discrimination and victimization despite legislative protections, posing continued risks for poor health outcomes and marginalization. Evaluation of factors (e.g., implementation strategies, systems of accountability) that influence the effectiveness of state-level polices on the reported experiences of discrimination and victimization among SGM people is needed.

Psychometric evaluation of the muscle dysmorphic disorder inventory (MDDI) among gender-expansive people.

PURPOSE: Muscle dysmorphia is generally classified as a specific form of body dysmorphic disorder characterized by a pathological drive for muscularity and the preoccupation that one is too small or not sufficiently muscular. The majority of research on the condition has been conducted in cisgender men with a paucity of literature on gender minority people, a population that is at risk for muscle dysmorphia. One of the most widely used measures of muscle dysmorphia symptoms, the Muscle Dysmorphic Disorder Inventory (MDDI), has not been psychometrically validated for use in gender minority samples, the aim of the present study. METHODS: We evaluated the psychometric properties of the MDDI in a sample of 1031 gender-expansive individuals (gender minority people whose gender identity differs from that assumed for their sex assigned at birth and is not exclusively binary man or woman) aged 18-74 who were part of The PRIDE Study, a large-scale, U.S., longitudinal cohort study. RESULTS: Using a two-step, split-sample exploratory and confirmatory factor analytic approach, we found support for the original three-factor structure of the measure. The subscales showed adequate internal consistency, and convergent validity was supported based on significant associations of the MDDI subscale scores with theoretically related scores on a widely used measure of disordered eating. CONCLUSIONS: These findings provided novel support for adequate psychometric properties of the MDDI in a sample of gender-expansive individuals, facilitating the use of this measure in future research on muscle dysmorphia in this understudied and at-risk population.

Gender-expansive describes gender identities that do not fit within the binary gender identity system, such as man or woman. We asked gender-expansive participants in The PRIDE Study to fill out a widely used survey about muscle dysmorphia (when someone is worried about not being muscular enough). We found that this issue about muscularity has three parts for gender-expansive people: (1) a desire to be bigger and more muscular, (2) dissatisfaction with the way their body looks, and (3) problems with normal life functions. We find that this survey is appropriate for use in gender-expansive people. These results can help providers and researchers understand the muscle-related problems that gender-expansive people face.

Migraine, Migraine Disability, Trauma, and Discrimination in Sexual and Gender Minority Individuals.

OBJECTIVE: This study sought to describe migrainous headache frequency and severity and to examine the relationship between trauma, discrimination, and migraine-associated disability in a sample of sexual and/or gender minority (SGM) adults. METHODS: We performed a cross-sectional study of SGM people in The Population Research in Identity and Disparities for Equality (PRIDE) Study from August-October 2018. The primary exposure was any trauma or discrimination, regardless of attribution. The primary outcome was moderate-severe migraine disability, as defined by a Migraine Disability Assessment (MIDAS) Questionnaire score ≥11. We performed descriptive analysis comparing respondents with any migrainous headache to those without. Multivariable logistic regression examined the association between trauma/discrimination and migraine disability, controlling first for sociodemographic and clinical factors and then for psychiatric comorbidities. RESULTS: Of the 3,325 total respondents, 1,126 (33.9%) screened positive for migrainous headache by ID-Migraine criteria. Most people with migraine self-reported moderate (n=768, 68.2%) or severe (n=253, 22.5%) intensity. The median MIDAS score was 11 (interquartile range [IQR] 5-25). Most respondents with migraine (n=1055, 93.7%) reported a history of trauma or discrimination. In unadjusted analysis, exposure to both trauma and discrimination was associated with higher odds of moderate-severe disability (OR 1.76, 95% CI 1.34-2.32). After adjustment for self-reported psychiatric comorbidities of anxiety, depression, and post-traumatic stress disorder, this association lost statistical significance. CONCLUSION: Migrainous headache is common among our sample of SGM adults, and prior experiences with trauma and discrimination is associated with increased migraine disability. Our findings suggest that psychiatric comorbidities play a significant role in this relationship, identifying a potentially modifiable risk factor for disability in SGM people with migraine.

Psychometric validation of the Muscle Dysmorphic Disorder Inventory (MDDI) among U.S. transgender men.

Muscle dysmorphia (MD) is characterized by a pervasive belief or fear of insufficient muscularity and an elevated drive for muscularity, representing the pathological and extreme pursuit of muscularity. Psychometric properties of one of the most widely used measures of MD symptoms-the Muscle Dysmorphic Disorder Inventory (MDDI)-have yet to be evaluated in transgender men despite emerging evidence suggesting differential risk for MD symptoms in this population. In this study, we assessed the psychometric properties of the MDDI in a sample of 330 transgender men ages 18-67 years who participated in a large-scale national longitudinal cohort study of sexual and gender minority adults in the U.S. Using a two-step, split-sample approach, an initial exploratory factor analysis supported a three-factor structure and a subsequent confirmatory factor analysis of a re-specified three-factor model demonstrated good overall fit (χ2/df = 1.84, CFI =0.94, TLI =0.92, RMSEA =0.07 [90% CI =0.05,.09], SRMR =0.08). Moreover, results supported the internal consistency and convergent validity of the MDDI subscales in transgender men. Findings inform the use of the MDDI among transgender men and provide a foundation to support further work on the MDDI and MD symptoms among gender minority populations.

Associations among romantic and sexual partner history and muscle dysmorphia symptoms, disordered eating, and appearance- and performance-enhancing drugs and supplement use among cisgender gay men.

This study examined relationship status (e.g., single versus not single) and number of sexual partners in relation to muscularity- and disordered eating-related attitudes and behaviors among 1090 cisgender gay men enrolled in The PRIDE Study in 2018. Participants completed measures assessing muscle dysmorphia (MD) symptoms, disordered eating attitudes and behaviors, and appearance- and performance-enhancing drug or supplement (APEDS) use. In linear regression models adjusting for theoretically relevant covariates, neither relationship status nor number of past-month sexual partners was associated with disordered eating attitudes. In terms of MD symptoms, single (versus not single) relationship status was associated with greater appearance intolerance, and a greater number of sexual partners was associated with greater drive for size and functional impairment. In adjusted logistic regression models, a greater number of past-month sexual partners was associated with use of anabolic-androgenic steroids, synthetic performance-enhancing substances, protein supplements, and creatine supplements, as well as greater likelihood of engaging in compelled/driven exercise. Across all associations, effect sizes were generally small. Overall, results support that inquiring about sexual partners may have utility in evaluating risk for muscularity-oriented attitudes and behaviors among cisgender gay men. Future work will need to replicate these findings, particularly in more diverse samples.

Do Ask, Tell, and Show: Contextual Factors Affecting Sexual Orientation and Gender Identity Disclosure for Sexual and Gender Minority People.

Purpose: Sexual and gender minority (SGM) people-including members of lesbian, gay, bisexual, transgender, and queer communities-remain underrepresented in health research due to poor collection of sexual orientation and gender identity (SOGI) data. We sought to understand the contextual factors affecting how SGM research participants interact with SOGI questions to enhance participant experience and increase the accuracy and sensitivity of research findings. Methods: We recruited SGM adults for in-person semi-structured focus groups or online cognitive interviews from 2016 to 2018. During focus groups and cognitive interviews, we asked participants to respond to SOGI question sets. We employed template analysis to describe the contextual factors that affected SGM participants' responses to SOGI questions. Results: We had a total of 74 participants, including 55 participants organized into nine focus groups and 19 participants in cognitive interviews. Most self-identified as a sexual minority person (88%), and 51% identified as a gender minority person. Two main themes were: (1) the need to know the relevance (of why SOGI questions are asked) and (2) the importance of environmental and contextual cues (communicating physical safety and freedom from discrimination that influenced SOGI disclosure). Conclusions: Contextualizing the relevance of SOGI data sought could help improve the accuracy and sensitivity of data collection efforts. Environmental cues that communicate acceptance and safety for SGM individuals in research settings may support disclosure. Researchers should consider these contextual factors when designing future studies to improve research experiences for SGM individuals and increase the likelihood of future participation.
