Omitted data in randomized controlled trials for anxiety and depression: A systematic review of the inclusion of sexual orientation and gender identity

Sociodemographic representation in randomized controlled trials for anxiety-related disorders in the U.S.: A systematic review (1993-2023)

Cognitive behavioral therapies have been identified as evidence-based treatments for anxiety-related disorders. However, data supporting the effectiveness of these treatments have been largely collected from participants with majoritized identities, potentially limiting the extent to which they can be considered "evidence-based" for clients from minoritized groups. The current review examined sociodemographic representation and quality of sociodemographic reporting in randomized controlled trials for anxiety-related disorders in the U.S. between 1993 and 2023. We conducted a systematic literature review of U.S.-based randomized controlled trials of cognitive behavioral therapies for anxiety-related disorders, extracted data on sociodemographic variables, and rated quality of reporting. Data from 55 eligible studies (N = 4492) indicated that white and female identities were overrepresented relative to the U.S. population, with variables like disability status, sexual orientation, and religious identification consistently ignored. In addition, quality of reporting was generally poor (mean = 3.6 out of 10), with many studies failing to account for demographic variables in their analyses or description of study limitations. Publication year, sample size, and NIH funding status did not significantly predict gender representation (% women), ethnoracial representation (% white), or quality of reporting. These findings underscore the importance of critically evaluating to whom "evidence-based" treatments apply and increasing diversity of clinical samples, to ensure that evidence-based treatments are inclusive. Recommendations for future research, clinical implications, and limitations are discussed.

Mindfulness enhances cognitive functioning: a meta-analysis of 111 randomized controlled trials

BACKGROUND

Currently no comprehensive meta-analysis of MBI efficacy on global and unique cognitive subdomains exist.

METHOD

Examined the effects of MBIs on global cognition and 15 cognitive subdomains. Inclusion criteria: meditation naïve participants; randomized controlled trial; outcome included one objective or subjective cognitive functioning measure; primary focus was teaching mindfulness skills. Exclusion criteria: inadequate data; one-session ; control condition contained any MBI component. Robust variance estimation and moderator analyses controlling for presence of treatment fidelity were conducted.

RESULTS

One-hundred-and-eleven RCTs (n = 9,538) met eligibility criteria. MBIs had small-to-moderate significant effects on global cognition, executive attention, working memory accuracy, inhibition accuracy, shifting accuracy, sustained attention, and subjective cognitive functioning (vs. waitlist/no-treatment, g = 0.257-0.643; vs. active controls, g = 0.192-0.394). MBIs did not impact executive functioning (EF) latency indices, verbal fluency, processing speed, episodic memory, and cognitive error. Treatment effects were stronger for those with elevated psychiatric symptoms vs. healthy controls, and medical samples, studies with complete-case (vs. intention-to-treat) analysis, face-to-face (vs. self-guided) delivery, and non-standard (vs. standard MBI).

CONCLUSION

MBIs consistently yielded small-to-moderate yet practically meaningful effect sizes on global cognition and six cognitive subdomains that captured accuracy vs. latency-based indices of EF and sustained accuracy.

Cross-cultural validation and measurement invariance of anxiety and depression symptoms: A study of the Brief Symptom Inventory (BSI) in 42 countries

BACKGROUND

Depression and anxiety are among the most prevalent mental health issues experienced worldwide. However, whereas cross-cultural studies utilize psychometrically valid and reliable scales, fewer can meaningfully compare these conditions across different groups. To address this gap, the current study aimed to psychometrically assess the Brief Symptomatology Index (BSI) in 42 countries.

METHODS

Using data from the International Sex Survey (N = 82,243; Mage = 32.39; SDage = 12.52; women: n = 46,874; 57 %), we examined the reliability of depression and anxiety symptom scores of the BSI-18, as well as evaluated evidence of construct, invariance, and criterion-related validity in predicting clinically relevant variables across countries, languages, genders, and sexual orientations.

RESULTS

Results corroborated an invariant, two-factor structure across all groups tested, exhibiting excellent reliability estimates for both subscales. The 'caseness' criterion effectively discriminated among those at low and high risk of depression and anxiety, yielding differential effects on the clinical criteria examined.

LIMITATIONS

The predictive validation was not made against a clinical diagnosis, and the full BSI-18 scale was not examined (excluding the somatization sub-dimension), limiting the validation scope of the BSI-18. Finally, the study was conducted online, mainly by advertisements through social media, ultimately skewing our sample towards women, younger, and highly educated populations.

CONCLUSIONS

The results support that the BSI-12 is a valid and reliable assessment tool for assessing depression and anxiety symptoms across countries, languages, genders, and sexual orientations. Further, its caseness criterion can discriminate well between participants at high and low risk of depression and anxiety.

Common practices for sociodemographic data reporting in digital mental health intervention research: a scoping review

BACKGROUND

The ability of digital mental health interventions (DMHIs) to reduce mental health disparities relies on the recruitment of research participants with diverse sociodemographic and self-identity characteristics. Despite its importance, sociodemographic reporting in research is often limited, and the state of reporting practices in DMHI research in particular has not been comprehensively reviewed.

OBJECTIVES

To characterise the state of sociodemographic data reported in randomised controlled trials (RCTs) of app-based DMHIs published globally from 2007 to 2022.

METHODS

A scoping review of RCTs of app-based DMHIs examined reporting frequency for 16 sociodemographic domains (eg, gender) and common category options within each domain (eg, woman). The search queried five electronic databases. 5079 records were screened and 299 articles were included.

RESULTS

On average, studies reported 4.64 (SD=1.79; range 0-9) of 16 sociodemographic domains. The most common were age (97%) and education (67%). The least common were housing situation (6%), residency/location (5%), veteran status (4%), number of children (3%), sexual orientation (2%), disability status (2%) and food security (<1%). Gender or sex was reported in 98% of studies: gender only (51%), sex only (28%), both (<1%) and gender/sex reported but unspecified (18%). Race or ethnicity was reported in 48% of studies: race only (14%), ethnicity only (14%), both (10%) and race/ethnicity reported but unspecified (10%).

CONCLUSIONS

This review describes the widespread underreporting of sociodemographic information in RCTs of app-based DMHIs published from 2007 to 2022. Reporting was often incomplete (eg, % female only), unclear (eg, the conflation of gender/sex) and limited (eg, only options representing majority groups were reported). Trends suggest reporting has somewhat improved in recent years. Diverse participant populations must be welcomed and described in DMHI research to broaden learning and the generalisability of results, a prerequisite of DMHI's potential to reduce disparities in mental healthcare.

A patient-centered model of mental health care for trauma and minority stress in transgender and gender diverse people: A bottom-up network analysis

Transgender and gender diverse (TGD) individuals are disproportionately exposed to traumatic and high-impact minority stressors which can produce an array of transdiagnostic symptoms. Some clinical presentations align well with established evidence-based treatments, but others may require patient-centered modifications or combined approaches to address treatment needs. In this study, we employed a novel, bottom-up approach to derive insights into preferred intervention strategies for a broad range of trauma- and TGD-minority stress-related expressions of clinical distress. Participants (18 TGD individuals, 16 providers) completed a q-sort task by first sorting cards featuring traumatic experiences and/or minority stressors and transdiagnostic psychiatric symptoms into groups based on perceived similarity. Next, participants sorted interventions they believed to be most relevant for addressing these concerns/symptoms. We overlayed networks of stressors and symptoms with intervention networks to evaluate preferred intervention strategies. TGD networks revealed transdiagnostic clustering of intervention strategies and uniquely positioned the expectancy of future harm as a traumatic stressor. Provider networks were more granular in structure; both groups surprisingly emphasized the role of self-defense as intervention. While both networks had high overlap, their discrepancies highlight patient perspectives that practical, material, and structural changes should occur alongside traditional clinical interventions.

Intercultural adaptation and influencing factors analysis of the Chinese version of the anxiety scale for the older adults in a long-term care population

Objective

The purpose of this study was to translate the Geriatric Anxiety Scale-Long-Term Care into Chinese and to assess its reliability and validity in a long-term care population, as well as to explore factors contributing to anxiety in older adults requiring long-term care.

Methods

The study recruited 399 older adults residents requiring long-term care and used the Brislin double translation-back-translation method to create the initial Chinese version of the Geriatric Anxiety Scale-Long-Term Care. The study used internal consistency and split-half reliability to assess the reliability of the scale, as well as exploratory factor analysis, validation factor analysis, and content validity to assess the validity of the scale. Linear regression was used to analyze the relationship between the independent variables and anxiety levels in the long-term care population.

Results

The Cronbach's coefficient value of the Chinese version of the Geriatric Anxiety Scale-Long-Term Care was 0.81, and the split-half reliability was 0.80. The results of exploratory factor analysis showed support for a one-dimensional factor structure. The results of the validation factor analysis indicated a good fit for the one-factor model. Gender (β = 0.190, 95% CI:0.540 ~ 1.546, p < 0.001), self-rated health (β = 0.220, 95% CI:0.379 ~ 0.953, p < 0.001), life satisfaction (β = -0.315, 95% CI: -1.355 ~ -0.734, p < 0.001) and participation in activities (β = -0.106, 95% CI: -1.122 ~ -0.084, p < 0.05) were significant predictors of anxiety levels in the long-term care population.

Conclusion

The Chinese version of the Geriatric Anxiety Scale-Long-Term Care has good reliability and validity in the long-term care population. The Geriatric Anxiety Scale-Long-Term Care is effective in assessing the anxiety level of the Chinese long-term care older adults population and provides an opportunity to detect and observe anxiety disorders in the long-term care population.

Suicidal Ideation Disparities Among Transgender and Gender Diverse Compared to Cisgender Community Health Patients

BACKGROUND

Transgender and gender diverse (TGD) individuals experience more severe psychological distress and may be at higher risk for suicide compared to cisgender individuals. The existing literature largely consists of small-sample studies that do not assess subgroup differences.

OBJECTIVE

To examine rates of self-reported suicidal ideation among four TGD groups compared to cisgender individuals.

DESIGN

Data were extracted from the electronic health records of patients receiving primary care at a community health center specializing in sexual and gender minority health. A logistic regression was used to examine the relationship between sociodemographic variables and the presence of current suicidal ideation.

PARTICIPANTS

29,988 patients receiving care at a community health center in Northeastern US between 2015 and 2018.

MAIN MEASURES

Demographic questionnaire, 9-item Patient Health Questionnaire KEY RESULTS: Younger age, sexual and gender minority identity, and public/grants-based insurance were associated with significantly higher odds of suicidal ideation. Relative to cisgender men, transgender men (OR=2.08; 95% CI=1.29-3.36; p=.003), transgender women (OR=3.08; 95% CI=2.05-4.63; p<.001), nonbinary (NB) individuals assigned male at birth (AMAB; OR=3.55; 95% CI=1.86-6.77; p<001), and NB individuals assigned female at birth (AFAB; OR=2.49; 95% CI=1.52-4.07; p<001) all endorsed significantly higher odds of current suicidal ideation, controlling for age, race, ethnicity, sexual orientation, and insurance status. Larger proportions of transgender women (23.6%) and NB AMAB individuals (26.7%) reported suicidal ideation not only compared to cisgender men (6.1%) and women (6.6%), but also compared to transgender men (17.4%; χ²[5, n=25,959]=906.454, p<0.001).

CONCLUSIONS

TGD patients were at significantly increased risk of suicidal ideation, even after accounting for age, race, ethnicity, sexual orientation, and insurance status. Findings suggest distinct risk profiles by assigned sex at birth. Consistent assessment of and intervention for suicidal ideation should be prioritized in settings that serve TGD patients.

Diversity, Equity, and Inclusion in Clinical Trials

Minority groups are vastly underrepresented in clinical trial participants and leadership. Because these studies provide innovative and revolutionary treatment options to patients with cancer and have the potential to extend survival, it is imperative that public and private stakeholders, as well as hospital and clinical trial leadership, prioritize equity and inclusion of diverse populations in clinical trial development and recruitment strategies. Achieving equity in clinical trials could be an important step in reducing the overall cancer burden and mortality disparities in vulnerable populations.

Mental health services use and depressive symptom scores among gay and bisexual men in Canada

PURPOSE

To evaluate the association between mental health services (MHS) use and depressive symptom scores among gay and bisexual men (GBM) and compare with heterosexual men in Canada.

METHODS

We used data from the 2015-2016 cycles of the Canadian Community Health Survey. Depressive symptoms were assessed using the PHQ-9 questionnaire (prior two weeks). MHS consultations with any licensed mental health professional (prior year) were categorized as 0, 1, 2-11, ≥ 12. We fit linear regression models to quantify the associations between MHS use and PHQ-9 scores, with an interaction term for sexual identity (GBM and heterosexual men). Models were adjusted for socioeconomic and health-related indicators.

RESULTS

Among 21,383 men, 97.3% self-identified as heterosexual and 2.7% as GBM. Compared to heterosexual men, GBM used any MHS (21% vs. 10%, p < 0.05) and consulted ≥ 2 health professionals for their mental health (6% vs. 2%, p < 0.05) in the preceding year more frequently. Overall, mean PHQ-9 scores were higher among GBM compared to heterosexual men (3.9 vs. 2.3, p < 0.05). Relative to no consultations, higher MHS use (2-11, ≥ 12 consultations) was associated with higher PHQ-9 scores (1.4-4.9 points higher). Associations between MHS use and PHQ-9 scores did not differ statistically between GBM and heterosexual men.

CONCLUSION

Our findings were inconclusive in demonstrating a difference between heterosexual men and GBM for the association between MHS use and PHQ-9 scores. However, GBM consistently had higher average PHQ-9 scores for every category of consultations. Considering the higher use of MHS and higher burden of depressive symptoms among GBM, more research is needed.

Looking into the LGB affirmative therapies over the last fifty years - a mixed method review synthesis

In the past few decades, affirmative therapies for sexual minorities have burgeoned. These are appropriate therapies but often there is a lack of adequate research. We set out to study the research evidence available. For this mixed-methods review, we identified 15 studies looking into the experiences of lesbian, gay and bisexual people in psychological therapies. These included nine qualitative, five quantitative and one mixed method studies. Minority stress hypothesis may explain some of the major difficulties LGB individuals face. Studies showed computer based therapies may reduce or even eliminate unhelpful responses on part of the therapist. Challenges related to confidentiality and privacy in this context remain. Therapists may focus on minority stress but other stressors and not just discrimination may contribute to various mental health problems and their clinical presence. And finally, divergent findings found internalized homophobia may best explain discrimination-based minority stress and that therapist self-disclosure of own sexuality produced better results than the therapists who did not self-disclose. These findings are discussed and future directions for research are identified.

Lack of Representation in Psychiatric Research: A Data-Driven Example From Scientific Articles Published in 2019 and 2020 in the American Journal of Psychiatry

OBJECTIVE

The authors examined representation and accuracy of descriptions of sociodemographic identities in psychiatric research through quantifying data contained in recently published articles from a high-impact psychiatry journal.

METHODS

Sociodemographic data were aggregated from articles (i.e., studies that provide information on individual samples) published in the American Journal of Psychiatry in 2019 and 2020 (N=125). Articles were coded by two raters for sociodemographic data, acknowledgment of lack of representation as a limitation, and focus on health disparities or inequities.

RESULTS

While 90% of studies provided the age of participants and 84% provided information about the sex/gender of participants, only 43% presented information about the racial or ethnicity identities of participants. One study reported the sexual identity of participants. Lack of representation relative to 2019 U.S. Census data was found for multiple racial groups, Latino/Hispanic individuals, and women (genetic studies only). Only 25% of studies acknowledged lack of representation as a limitation, and two studies focused on health disparities or inequities.

CONCLUSIONS

These findings highlight a need to increase representation in psychiatric research and improve accuracy of language when describing the sociodemographic characteristics of participants.

"Why don't behavior analysts do something?"1 Behavior analysts' historical, present, and potential future actions on sexual and gender minority issues

For thousands of years, societies actively practiced the oppression, persecution, and dehumanization of sexual and gender minority (SGM) people (e.g., lesbian, gay, bisexual, transgender, and queer individuals). Rekers and Lovaas' (1974) study is part of that history within behavior analysis. Following requests for retraction, the Society for the Experimental Analysis of Behavior and LeBlanc (2020) issued a formal Expression of Concern about the work. Continued conversation and debate have followed. First, we contextualize debate around retraction of Rekers and Lovaas and the history of behavior analysts' work on SGM issues. Second, we propose 5 steps that leaders in behavior analysis can take with relative immediacy, and we describe 5 research areas that individual behavior analysts could pursue. We conclude that behavior analysts can contribute much toward the liberation of SGM individuals if we begin to bring our science to bear on pressing, socially significant issues facing SGM communities.

Review and Analysis of International Transgender Adult Primary Care Guidelines

Purpose: To examine and critique current international clinical practice guidelines (CPGs) related to providing primary care to transgender adults and to assess their applicability to practice. Methods: A review was conducted to obtain English language clinical guidelines. Guidelines included in this review were obtained from published journals and gray literature. Guidelines were critiqued using the AGREE II instrument. Results: Seventeen documents were included in the final review. Eleven were specifically designed for primary care practitioners, whereas the remaining six were deemed applicable to primary care. Overall, across the CPGs, the scope, purpose, and clarity of presentation were done well. However, the overall methodological rigor in guideline development was poor. Many CPGs included useful tools that could be helpful for the primary care practitioner. Conclusions: CPGs can be an important support for primary care providers' clinical practice with transgender people, particularly after having received limited formal education in transgender care. Improvements in transgender health CPG rigor and transparency are needed. Future CPGs would benefit from recommendations on the nuanced discussion of gender concepts and interpersonal communication that can create conflict in health care interactions.

Systematic review of gender bias in vortioxetine clinical trials

This paper evaluates gender bias in the published clinical trials of Vortioxetine. We conducted a systematic review of controlled clinical trials of Vortioxetine for the treatment of depression. The literature search was performed using MEDLINE and following the corresponding international recommendations. We identified 42 articles, of which 23 were included. The proportion of women ranged from 47%-75% and the percentage of women included in the 10,404 total patients sample was 65%. The separate analysis of the main variable between the subpopulations of men and women was only carried out in 3/23 publications included. In contrast, 6/23 trials analyzed secondary variables separated by sex. No trials discussed the results separately by sex. The proportion of women included was slightly higher than that in clinical trials of other antidepressants. However, the analysis of the main result or secondary variables by sex, as well as discussing the results separately by sex, are scarce. This gives rise to gender bias in these works.

A Systematic Review of Recommendations for Behavioral Health Services for Transgender and Gender Diverse Adults: The Three-Legged Stool of Evidence-Based Practice is Unbalanced

There is a growing literature of clinical recommendations for transgender and gender diverse (TGD) affirming behavioral health care, yet it is unknown to what extent these recommendations are rooted in evidence-based practice (EBP). This systematic review included 65 articles published between 2009 and 2018 with recommendations for behavioral health services with TGD adults, emphasizing general clinical care. Coded variables included type of article, participant demographics, aspects of EBP, and whether care was informed by objective assessment. Most articles did not equally draw from all components of EBP. Recommendations for specific clinical problems are increasingly available and address diversity within TGD communities. More research, including clinical trials adapting established interventions, is needed to inform state-of-the-art TGD-affirmative behavioral health care.

The Role of Implementation Science in Reducing Sexual and Gender Minority Mental Health Disparities

Owing to multiple and multilevel ecological factors, sexual and gender minority (SGM) populations exhibit persistent mental health disparities. SGM populations are also at increased risk for never being reached by evidence-based mental health care in real-world settings, which is essential for reducing these disparities. To be maximally effective in reducing these disparities, we must strive to bring our research findings into routine clinical care quickly. Implementation science can help SGM health researchers achieve this goal. This perspective outlines how researchers can use implementation science theories and methods to reduce SGM mental health disparities more efficiently and more durably.

Where Sexual Orientation Has No Name: Sexual Orientation Missing Data in the Canadian Community Health Survey (2005-2014)

This study used data from the Canadian Community Health Survey (CCHS) (2005-2014) to analyze the relationships between sexual orientation item nonresponse and interview language, conversation language, migration status (migrant-non-migrant), cultural background, sex, age, education level, and marital status in a cross-sectional sample over 18 (n = 351,713 participants). Item nonresponse rates oscillated between 0.87% in 2007 and 1.4% in 2014. Individuals who self-declared as belonging to cultural groups such as Chinese, South Asian, South East Asian, Arab, Indigenous and Other had higher nonresponse odds compared to people who self-identified as Whites. The results showed significant higher nonresponse odds among immigrants. Women had higher nonresponse rates. The likelihood of non-answer increased with age and decreased with education. French interviews, interviews in other languages and speaking both English and French produced less nonresponse. Contrary to common beliefs, sexual orientation questions are not too controversial. Sexual orientation nonresponse is low and stable over time suggesting that research participants are willing to answer sexual orientation questions. These findings highlight that immigrants and people who self-declare as belonging to different cultural groups may interpret the sexual orientation questions differently.

Correlations between healthcare provider interactions and mental health among transgender and nonbinary adults

Transgender and nonbinary patients have a wide array of experiences when attempting to access healthcare, including discrimination and having to educate providers about trans people. This study examines the mental health factors connected to transgender and nonbinary patients' experience with providers to determine the likelihood of transgender or nonbinary patients receiving respectful care after a provider knows about the patient's gender identity, and patients' experience of having to educate providers about trans people, controlling for sociodemographic factor. Using data from the 2015 United States Trans Survey (N = 27,715), chi-square tests of independence and multivariate logistic regressions were used to explore the odds of transgender or nonbinary individuals having a positive experience with a doctor or healthcare provider. Of the respondents, 24.31% experienced having to educate a provider about trans people when seeking care, and 62.90% experienced a provider knowing they were transgender or nonbinary and treating them with respect. Those experiencing depression and suicidal thoughts were significantly less likely to have had a provider treat them with respect, and significantly more likely to need to educate their providers. Gender, age, disability status, and educational level were significant across both variables; income was significant regarding having to educate a provider. Healthcare providers need ongoing training and education to improve their care of transgender and nonbinary patients, specifically around acknowledging the multiple backgrounds and experiences of such patients, including those related to mental health, gender, race, age, income, educational level, and disability.

Addressing Diversity in PTSD Treatment: Clinical Considerations and Guidance for the Treatment of PTSD in LGBTQ Populations

Purpose of review

Trauma exposure is widespread but is especially common among lesbian, gay, bisexual, transgender, and queer (LGBTQ) individuals. LGBTQ individuals also experience higher rates of discrimination, victimization, and minority stress which can complicate posttraumatic stress disorder (PTSD) treatment but also represent independent intervention targets. In this review, we highlight existing evidence-based practices, current limitations, and provide recommendations for care in the absence of established guidelines for treatment PTSD among LGBTQ patients.

Recent findings

Trauma-focused therapies (e.g., CPT, PE) and medications (e.g., SSRIs, SNRIs) have shown benefit for people with PTSD. However, evaluations of these interventions have failed to examine the role of LGBTQ identities in recovery from trauma, and existing PTSD treatments do not account for ongoing threat to safety or the pervasive minority stress experienced by LGBTQ patients. In addition, many LGBTQ patients report negative experiences with healthcare, necessitating increased education and cultural awareness on the part of clinicians to provide patient-centered care and, potentially, corrective mental health treatment experiences.

Summary

Providers should routinely assess trauma exposure, PTSD, and minority stress among LGBTQ patients. We provide assessment and screening recommendations, outline current evidence-based treatments, and suggest strategies for integrating existing treatments to treat PTSD among LGBTQ patients.

Sexual orientation and substance use treatment outcomes across five clinical trials of contingency management

Lesbian, gay, and bisexual (LGB) individuals have elevated rates of substance use disorders and present to treatment with more severe substance use problems. Despite this health disparity, recent reviews highlight the paucity of studies reporting sexual orientation in substance use research (e.g., Flentje, Bacca, & Cochran, 2015). Using data from 5 clinical trials of contingency management (CM), the current study investigated the impact of sexual orientation on 3 substance use outcomes: treatment retention, longest duration of abstinence, and percent negative samples submitted. Participants (N = 912; mean age = 36.6 years; 51.1% female; 45% African American, 42.2% Caucasian) were randomized to standard care in community-based intensive outpatient treatment (IOP) or the same plus CM. Patients identifying as LGB made up 10.6% of the sample. A significant proportion identified as bisexual (8.2% of the total sample). Regardless of sexual orientation, participants receiving CM achieved better treatment outcomes than those receiving IOP alone. There were no statistically significant differences between LGB and heterosexual participants in their response to IOP in general, and CM specifically, across all 3 treatment outcomes (ps > .05). However, equivalence testing revealed that outcomes were not statistically equivalent for LGB and heterosexual participants, with the exception of percentage of negative samples, which was equivalent within the CM group only. Differences in treatment response to CM and standard community-based IOP do not reach the level of statistical significance; however, in most cases, we cannot conclude that treatment response is equivalent for LGB and heterosexual individuals.

Using mobile technology to engage sexual and gender minorities in clinical research

INTRODUCTION

Historical and current stigmatizing and discriminatory experiences drive sexual and gender minority (SGM) people away from health care and clinical research. Being medically underserved, they face numerous disparities that make them vulnerable to poor health outcomes. Effective methods to engage and recruit SGM people into clinical research studies are needed.

OBJECTIVES

To promote health equity and understand SGM health needs, we sought to design an online, national, longitudinal cohort study entitled The PRIDE (Population Research in Identity and Disparities for Equality) Study that enabled SGM people to safely participate, provide demographic and health data, and generate SGM health-related research ideas.

METHODS

We developed an iPhone mobile application ("app") to engage and recruit SGM people to The PRIDE Study-Phase 1. Participants completed demographic and health surveys and joined in asynchronous discussions about SGM health-related topics important to them for future study.

RESULTS

The PRIDE Study-Phase 1 consented 18,099 participants. Of them, 16,394 provided data. More than 98% identified as a sexual minority, and more than 15% identified as a gender minority. The sample was diverse in terms of sexual orientation, gender identity, age, race, ethnicity, geographic location, education, and individual income. Participants completed 24,022 surveys, provided 3,544 health topics important to them, and cast 60,522 votes indicating their opinion of a particular health topic.

CONCLUSIONS

We developed an iPhone app that recruited SGM adults and collected demographic and health data for a new national online cohort study. Digital engagement features empowered participants to become committed stakeholders in the research development process. We believe this is the first time that a mobile app has been used to specifically engage and recruit large numbers of an underrepresented population for clinical research. Similar approaches may be successful, convenient, and cost-effective at engaging and recruiting other vulnerable populations into clinical research studies.

Systematic Review of Gender Bias in the Clinical Trials of New Long-Acting Antipsychotic Drugs

PURPOSE/BACKGROUND

This article evaluates gender bias in the published clinical trials of new long-acting antipsychotics.

METHODS/PROCEDURES

We conducted a review of controlled clinical trials of the new prolonged-release antipsychotics (aripiprazole, risperidone, or paliperidone) for the treatment of schizophrenia published in MEDLINE over the last 10 years and available in full text in English. The study followed the corresponding international recommendations.

RESULTS

We identified 132 trials, and of these, 40 met the inclusion and exclusion criteria. We found that only 36.41% of the total patients were women. The separate analysis of the main variable between the subpopulations of men and women was carried out in only 6 of the 40 works included. In contrast, in 15 trials, this analysis was performed on secondary variables, generally related to safety. Only 3 of the 40 trials discussed the results separately according to sex.

CONCLUSIONS

The clinical trials of long-acting atypical antipsychotic drugs show a far-from-negligible gender bias. Women are underrepresented, and the main and secondary variables are not analyzed separately according to gender. This is despite international recommendations establishing these criteria as part of a package of minimum requirements for meeting scientific validity and making results apt to extrapolate to the general population of patients.

Applying dialectical behaviour therapy to structural and internalized stigma with LGBTQ+ clients

Delivering research-supported intervention is increasingly important, given the growing emphasis on evidence-based practice in mental health treatment. When working with clients who hold marginalized identities, however, therapists may have questions about how to best tailor interventions, as treatments may not yet have demonstrated efficacy with under-represented populations. This paper describes potential strategies for using dialectical behaviour therapy (DBT) skills to help LGBTQ+ clients, guided by a theoretical model for understanding sexual stigma. Joining these two paradigms, suggestions are made for applications of skills that can help LGBTQ+ clients who are in DBT effectively interact with invalidating environments characterized by structural stigma. DBT-based strategies aimed at buffering clients from environmental invalidation and enhancing their skills in self-validation can help provide them with pathways towards affirming their own sexual orientation and gender identity. Examples from clinical cases are used to enhance understanding of skills application in practice.

The scientific pursuit of sexual and gender minority mental health treatments: Toward evidence-based affirmative practice

The time has arrived for psychological science to translate the accumulating empirical research regarding sexual and gender minority (SGM) mental health into evidence-based affirmative treatments for this population. Far from the unscientific, homophobic theories of the early 20th century, several recent efforts in psychological science are starting to pave the way for evidence-based SGM-affirmative mental health treatments. These efforts include (a) identifying clear treatment targets for SGM, (b) conducting treatment studies that test the efficacy of therapy for SGM populations, (c) increased reporting of sexual orientation and gender diversity in existing randomized controlled trials conducted with the general population, and (d) reducing stigma itself, which has heretofore impeded the resources necessary to produce scientific evidence about SGM-affirmative treatments. This article reviews this progress and outlines future research directions needed to advance evidence-based practice for SGM, including determining whether and how existing evidence-based treatments need to be adapted to address SGM-specific concerns, why SGM-affirmative treatments work, and for whom and under what conditions SGM-affirmative treatments work best. A program of research is described that attempts to address these questions through randomized controlled trials with strong comparison conditions, psychotherapy process research of current SGM-affirmative practice, and tests of treatment moderators. To the extent that the mental health profession continues to pursue these solutions, it can ensure the continued flourishing of this population, whose visibility and vibrancy likely represent the surest route toward improving public acceptance and therefore its future mental health.

Quantifying Sexual Orientation Among Homeless and Unstably Housed Women in a Longitudinal Study: Identity, Behavior, and Fluctuations Over a Three-Year Period

Sexual orientation has been linked to certain health conditions, and yet quantifying sexual orientation in longitudinal studies is challenging. This study examined different methods of accounting for sexual orientation in a cohort study of 300 homeless and unstably housed women followed every 6 months over 3 years. Altogether, 39.7% (n = 119) could be considered sexual minority at one or more time points based on identity and/or behavior; 16.3% (n = 49) reported shifts in sexual identity. Only 24.0% (n = 72) were identified as sexual minority through a single measure of sexual identity, 27.0% (n = 81) were identified with a single measure of identity and behavior, 33.0% (n = 99) were identified through annual measures of identity and behavior, and 22.0%-22.3% (n = 66-67) were identified through latent class analysis including all identity/behavior measures. This study found that sexual fluidity is common in unstably housed women, and many sexual minority women would be missed in longitudinal studies with different methods of accounting for sexual orientation.

Comparison of Treatment Outcomes Between Lesbian, Gay, Bisexual and Heterosexual Individuals Receiving a Primary Care Psychological Intervention

BACKGROUND

Lesbian, gay and bisexual individuals experience more anxiety and depression than heterosexual people. Little is known about their comparative treatment response to psychological interventions.

AIMS

To compare sociodemographic/clinical characteristics and treatment outcomes across sexual orientation groups, for adults receiving primary care psychological interventions from Improving Access to Psychological Therapies (IAPT) services in London, adjusting for possible confounders.

METHOD

Data from 188 lesbian women, 222 bisexual women, 6637 heterosexual women, 645 gay men, 75 bisexual men and 3024 heterosexual men were analysed from pre-treatment and last treatment sessions. Males and females were analysed separately.

RESULTS

Before treatment, lesbian and bisexual women were more likely to report clinical levels of impairment (Work and Social Adjustment Scale) than heterosexual women; there were no significant differences in depression (PHQ-9) or anxiety (GAD-7). Bisexual men were more likely to meet depression caseness than gay men but less likely to meet anxiety caseness than gay or heterosexual men. Compared with heterosexual women, lesbian and bisexual individuals showed smaller reductions in depression and impairment, controlling for age, ethnicity, employment, baseline symptoms, number of sessions and intervention type. Bisexual women experienced significantly smaller reductions in anxiety than heterosexual women and were less likely to show recovery or reliable recovery. There were no significant differences in treatment outcomes between gay, bisexual and heterosexual men.

CONCLUSIONS

Reasons for poorer outcomes in lesbian and bisexual women require investigation, for example lifetime trauma or stigma/discrimination regarding gender or sexual orientation in everyday life or within therapy services.

A tailored compassion-focused therapy program for sexual minority young adults with depressive symotomatology: study protocol for a randomized controlled trial

Background

Lesbian, gay, and bisexual (LGB) men and women represent one of the highest-risk populations for depressive symptomatology and disorders, with young LGB adults being at greatest risk. To date, there have been no randomized controlled trials (RCT) to specifically target depressive symptoms in young LGB adults. This is despite research highlighting unique predictors of depressive symptomatology in this population. Here we outline a protocol for an RCT that will test the preliminary efficacy of a tailored compassion-focused therapy (CFT) intervention for young LGB adults compared with a self-directed cognitive behavioral therapy (CBT) program with no specific tailoring for LGB individuals.

Methods

The CFT intervention consists of 8 units with self-directed reading and activities tailored to LGB young adults, and 8 x weekly 1-hour consultations with a therapist. The CBT intervention consists of 8 units with self-guided reading and activities, with 1 x 1-hour session with a therapist at the mid-point of therapy. Fifty LGB individuals with scores of 13 or above on the Beck Depression Inventory-II will be randomized to either the CFT or CBT condition. The primary outcome measure is depressive symptomatology. Secondary outcome measures are symptoms of anxiety, suicidal ideation, internalized homophobia, self-compassion, and shame and guilt proneness. Assessments will occur at pre-intervention, post-intervention, and at 3-month post-intervention.

Discussion

This study is an RCT to test the preliminary efficacy of an LGB-tailored compassion-focused intervention for young LGB adults with depressive symptomatology. If this intervention is efficacious, this could begin to address the substantial mental health disparities amongst sexual minorities.
