How do sexual and gender minority people acquire the capability for suicide? Voices from survivors of near-fatal suicide attempts.

Despite well-documented disparities by sexual and gender minority (SGM) status in suicide attempt and mortality rates, few studies have investigated the lived experiences that contribute to SGM people's disproportionate risk of suicide. Having a history of at least one near-fatal (or medically serious) suicide attempt serves as a proxy for suicide mortality, but no known study has involved SGM people who have made such an attempt. Ideation-to-action theories of suicide posit that individuals acquire the capability for suicide through repeated exposure to painful and provocative events - namely, traumatic, threatening, and risky experiences - that can diminish the pain and fear of death. Yet whether identity-specific features of acquired capability for suicide contribute to SGM people's disproportionate risk of suicide remains unknown. Drawing upon interviews with 22 SGM people who experienced a recent near-fatal suicide attempt, the current study sought to identify specific determinants of how SGM individuals acquire the capability to kill themselves, a potentially powerful, and modifiable, pathway to suicide. Results identified three SGM-specific contributors to the acquired capability for suicide: (1) identity invalidation during developmentally sensitive periods of childhood and adolescence that left participants feeling erased, invisible, and, in some cases, non-existent; (2) normalization of suicide within SGM social networks that increased acceptability and reduced the fear of suicide; and (3) structural stigma and SGM community trauma as habituating sources of pain that engendered feelings of exhaustion and positioned suicide as a reprieve from pervasive anti-SGM norms. This study demonstrates that dominant suicidology theories might need to be refined to account for the stigma-related determinants of SGM suicide. Further, this study reinforces the importance of qualitative methods for understanding the lived experience of suicide and calls for SGM-specific suicide prevention efforts to respond to stigma to support those SGM people who contemplate suicide.

A transdiagnostic minority stress intervention for gender diverse sexual minority women's depression, anxiety, and unhealthy alcohol use: A randomized controlled trial.

OBJECTIVE: To remedy the notable gap in evidence-based treatments for sexual minority women, this study tested the efficacy of a minority-stress-focused cognitive-behavioral treatment intended to improve this population's mental and behavioral health. METHOD: The intervention, EQuIP (Empowering Queer Identities in Psychotherapy), was adapted from a transdiagnostic cognitive-behavioral treatment as also recently adapted for sexual minority men. Sexual minority women at risk of mental and behavioral health problems (n = 19) and expert providers with this population (n = 12) shaped the treatment's development, including by supporting its primary focus on universal and minority-stress-focused processes underlying this population's disproportionately poor mental and behavioral health. The resulting treatment was then delivered to young adult sexual minority women (n = 60; M age = 25.58; 41.67% racial/ethnic minority; 43.33% transgender/nonbinary) experiencing depression/anxiety and past 90-day heavy alcohol use. RESULTS: Compared to waitlist (n = 30), participants randomized to immediately receive EQuIP (n = 30) experienced significantly reduced depression and anxiety (d = 0.85, 0.86, respectively); effects for alcohol use problems were smaller (d = 0.29) and marginally significant. In pre- to post-intervention pooled analyses, effect sizes for minority stress processes (mean d = .25) and universal risk factors (mean d = .48), through which the treatment was expected to work, were small and moderate, respectively, and in the expected direction. CONCLUSIONS: This study provides initial support for a minority-stress-focused transdiagnostic cognitive-behavioral treatment for sexual minority women. These first results can launch exploration of other mechanisms and modalities through which to equip this population with evidence-based support.

Brief online interventions for LGBTQ young adult mental and behavioral health: A randomized controlled trial in a high-stigma, low-resource context.

OBJECTIVE: To identify scalable interventions for improving sexual minority mental health and health-risk behavior, this study tested the efficacy of two self-guided online writing interventions-expressive writing and self-affirmation. To reach sexual minority young adults living in high-stigma, low-resource settings, we developed and tested these interventions in Appalachian Tennessee. METHOD: In consultation with sexual minority young adults (n = 10) and stakeholders (n = 10) living in Appalachian Tennessee, we adapted these two writing interventions that we then delivered to 108 local sexual minority young adults (Mage = 23.68, SD = 3.11). Participants, representing diverse sexual and gender identities and socioeconomic backgrounds, were randomly assigned to participate in a 3-session expressive writing intervention, self-affirmation intervention, or neutral control. Participants completed mental health and health-risk behavior measures at baseline, postintervention, and 3-month follow-up. RESULTS: Compared to the neutral control, expressive writing exerted 3-month improvements in depressive symptoms (d = 0.48) and general psychological distress (d = 0.36) whereas self-affirmation exerted improvement in suicidal ideation (d = 0.62) and drug abuse (d = 0.59). Participants who were exposed to greater contextual minority stressors common in rural regions (i.e., discrimination and victimization) experienced significantly greater 3-month reductions in depression from expressive writing and self-affirmation compared to control. Those who experienced greater discrimination also experienced significantly greater 3-month reductions in suicidality from self-affirmation compared to control. CONCLUSION: Brief writing interventions exert significant impact on the mental health of young adult sexual minorities, especially those exposed to minority stress. Future research can consider strategies for population-level implementation, especially in high-stigma, low-resource settings. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Project ESTEEM protocol: a randomized controlled trial of an LGBTQ-affirmative treatment for young adult sexual minority men's mental and sexual health.

BACKGROUND: Young gay and bisexual men disproportionately experience depression, anxiety, and substance use problems and are among the highest risk group for HIV infection in the U.S. Diverse methods locate the source of these health disparities in young gay and bisexual men's exposure to minority stress. In fact, minority stress, psychiatric morbidity, substance use, and HIV risk fuel each other, forming a synergistic threat to young gay and bisexual men's health. Yet no known intervention addresses minority stress to improve mental health, substance use problems, or their joint impact on HIV risk in this population. This paper describes the design of a study to test the efficacy of such an intervention, called ESTEEM (Effective Skills to Empower Effective Men), a 10-session skills-building intervention designed to reduce young gay and bisexual men's co-occurring health risks by addressing the underlying cognitive, affective, and behavioral pathways through which minority stress impairs health. METHODS: This study, funded by the National Institute of Mental Health, is a three-arm randomized controlled trial to examine (1) the efficacy of ESTEEM compared to community mental health treatment and HIV counseling and testing and (2) whether ESTEEM works through its hypothesized cognitive, affective, and behavioral minority stress processes. Our primary outcome, measured 8 months after baseline, is condomless anal sex in the absence of PrEP or known undetectable viral load of HIV+ primary partners. Secondary outcomes include depression, anxiety, substance use, sexual compulsivity, and PrEP uptake, also measured 8 months after baseline. DISCUSSION: Delivering specific stand-alone treatments for specific mental, behavioral, and sexual health problems represents the current state of evidence-based practice. However, dissemination and implementation of this one treatment-one problem approach has not been ideal. A single intervention that reduces young gay and bisexual men's depression, anxiety, substance use, and HIV risk by reducing the common minority stress pathways across these problems would represent an efficient, cost-effective alternative to currently isolated approaches, and holds great promise for reducing sexual orientation health disparities among young men.

SloR modulation of the Streptococcus mutans acid tolerance response involves the GcrR response regulator as an essential intermediary.

Streptococcus mutans, the primary causative agent of human dental caries, grows as a biofilm on the tooth surface, where it metabolizes dietary carbohydrates and generates acid byproducts that demineralize tooth enamel. A drop in plaque pH stimulates an adaptive acid-tolerance response (ATR) in this oral pathogen that allows it to survive acid challenge at pHs as low as 3.0. In the present study, we describe the growth of an S. mutans mutant, GMS901, that harbours an insertion-deletion mutation in gcrR, a gene that encodes a transcriptional regulatory protein. The mutant is acid-sensitive and significantly compromised in its ATR relative to the UA159 wild-type progenitor strain. Consistent with these findings are the results of real-time quantitative RT-PCR (qRT-PCR) experiments that support the GcrR-regulated expression of known ATR genes, including atpA/E and ffh. Although we observed gcrR transcription that was not responsive to acidic pH, we did note a significant increase in gcrR expression when S. mutans cells were grown in a manganese-restricted medium. Interestingly, the results of gel mobility shift assays indicate that the S. mutans SloR metalloregulatory protein is a potential regulator of gcrR by virtue of its manganese-dependent binding to the gcrR promoter region, and expression studies support the hypothesis that sloR transcription is responsive to manganese deprivation and acidic pH. Taking these results together, we propose that SloR-Mn modulates S. mutans gcrR expression as part of a general stress response, and that GcrR acts downstream of SloR to control the ATR.
