The socioecology of sexual minority stigma
The socioecology of sexual minority stigma: Advancing theory on stigma-based mechanisms underlying sexual orientation-based disparities in health — This article discusses how sexual minority stigma (sometimes referred to as homophobia and biphobia) in modern societies may manifest itself in many different forms across socioecological levels, as suggested in earlier research. But what are the implications for research to view sexual minority stigma as a true socioecological system? What are the theoretical tenets that underlie this interpretation? How can research better account for these tenets in future research? And how can this help improve our understanding of how societal stigma systemically drives sexual orientation-based disparities in health? Read more about these questions in this article on the socioecology of sexual minority stigma.

The Socioecology of Sexual Minority Stigma: Data Harmonization to Address Confounding Bias and Investigate Cross-Level Mental Health Effects (NIMH R01)
While an expanding body of theory-driven research has consistently shown how factors related to structural sexual minority stigma may drive sexual orientation-based mental health disparities, US-based evidence has been hampered by single stand-alone indicators of structural stigma, leading to important risks for confounding bias. Existing public health datasets have not independently been able to facilitate research that could fully account for such confounding bias, leading to distorted results. Together with newly developed comprehensive structural sexual minority stigma indices spanning from 2008-2023, the harmonization and integration of data from over 2.5 million Americans from a large number of US public health datasets will enable advanced cross-sectional and longitudinal multilevel models to examine how structural sexual minority stigma at macro (i.e., state) level drives and sustains sexual orientation-based disparities in depressive symptoms and suicidality outcomes across the lifespan and across two transformative decades for sexual minority emancipation.

The Mental Health Consequences of Life Course-Varying Exposure to Structural Sexual Minority Stigma: Advancing Causal Inference Using Longitudinal Models Moderated by Sexual Orientation (NIMH R03)
An expanding body of theory-driven research has consistently shown how factors related to sexual minority stigma, including structural, interpersonal, and intrapersonal factors, may drive sexual orientation-based mental health disparities. However, public health research has so far been unable to produce strong causal, longitudinal evidence on how structural forms of sexual minority stigma may jeopardize mental health outcomes among sexual minorities, including suicidal ideation, suicide attempts, and depressive symptoms. The proposed secondary analysis of a large public health dataset (Add Health) will include advanced three-level multi-membership longitudinal models to examine three key aspects yet missing to facilitate causal inferencing regarding the mental health sequelae of structural sexual minority stigma exposure.

Suicide Prevention for Sexual and Gender MInority Youth and Young Adults (NIMH R61/R33)
Sexual and gender minority (SGM) youth and emerging adults are at high risk of suicide attempts and death by suicide, and no known suicide prevention programs exist for this vulnerable population. The research project will adapt and test an intervention that integrates patient navigation with safety planning to prevent suicide. This intervention program for SGM youth and emerging adults is designed to target mechanisms that theoretically underlie suicide.

ONE WHO ALLOWS OPPRESSION, SHARES THE CRIME
Imagine talking to a therapist and instead of listening, they will tell you that there’s something innately wrong with you. This kind of ‘conversion therapy’ is still happening in the US and even in the Netherlands, mostly with LGBTQ+ youth. EUR alumnus Dr. Arjan van der Star (31) works as a postdoctoral researcher at San Diego State University and studies how harmful factors like these may help explain why LGBTQ+ individuals continue to report lower mental and physical health than the general population. His research also indicates that a supportive environment may undo the negative effects of stigma and prejudice, so health might be improved again.

COMPLEX INTERPLAY WHEN STIGMA SHAPES THE MENTAL HEALTH OF SEXUAL MINORITIES
It is a known fact that sexual minorities are at a higher risk of developing poor mental health, when compared to heterosexuals. The stigma that sexual minorities face has been regarded as potentially the primary cause of this. A new thesis from Karolinska Institutet offers an insight into how stigma-related factors may work in a broader socio-ecological system, considering the complex interaction between structural, interpersonal and individual factors.

Biography
Dr. Arjan van der Star, Ph.D., M.Sc. (he/him) is a social epidemiologist and public health researcher investigating sexual and gender minority mental health. Dr. Van der Star’s research focuses on the complex mechanisms underlying sexual orientation-based and gender identity-based mental health disparities by examining 1) how sexual and gender minority stigma and related stressors may explain disparities in mental health, 2) how such stigma may operate within a multi-level socio-ecological system surrounding sexual and gender minorities, and 3) how stigma-related factors may interact across these various levels of sexual and gender minority stigma. Hence, through his research, Dr. Van der Star primarily aims to further the theoretical understanding of what drives and causes adverse mental health among sexual and gender minorities, to inform effective policies on how to reduce the risk for such adverse mental health outcomes, but also, by illuminating the mechanisms underlying the link between sexual and gender minority stigma and poor mental health, to inform affirming psychotherapy tailored for sexual and gender minorities.
Dr. Van der Star is currently an Associate Research Professor in the Department of Psychology at San Diego State University (SDSU) and a Research Scientist with the SDSU Research Foundation. He directs the Society, Equity, Stigma, and Health (SESH) Lab and is the co-director of the Center for the Integration of Public Health and Clinical Psychology in Health Equity Research (CIPHER) at SDSU. Dr. Van der Star is the Principal Investigator of two NIMH-funded epidemiological research projects as well as the Project Director of an NIMH-funded suicide prevention intervention study. He also serves as the President of the Sexual and Gender Minority Health section of the European Public Health Association. Dr. Van der Star obtained B.Sc. and M.Sc. degrees from Erasmus University Rotterdam in 2011 and 2013, respectively, and a Ph.D. degree from Karolinska Institutet in September 2020, which included a fellowship at the Yale School of Public Health (2018-2019).
