An Exploratory Study of Environmental Stress in Four High Violent Crime Cities: What Sets Them Apart?

Understanding the social contexts of violent crime remains controversial in the literature. In the current study, we examine common social contexts in four cities (Houston, TX, Baltimore, MD, Jackson, MS, Wilmington, DE). Data were examined in two studies. In the first, each city was compared to national county-level data on health outcomes. In the second, communities within the four cities were examined for correlates of crime. Results suggest that some common social contexts emerge: high STD rates, air pollution, single-parent homes, insufficient food resources and sleep, residential segregation, housing cost burdens, comparatively few older adults and comparatively more females, were common among the four high-violence cities. By contrast, all four cities unexpectedly had uncommonly low suicide rates compared to the national average. At the community level, unemployment, community stress, median household income, and population density all correlated with criminal outcomes. High-violence cities tended to have higher proportions of Black residents, however community level evaluations suggested that class-related issues, not race per se, was correlated with violent crime.

Development and Validation of Two Abbreviated Intraminority Gay Community Stress Scales

Social stressors stemming from within the gay community might render gay and bisexual men vulnerable to mental health problems. The 20-item intraminority Gay Community Stress Scale (GCSS) is a reliable measure of gay community stress, but the scale’s length limits its widespread use in sexual minority mental health research. Using three independent samples of gay and bisexual men, the present research developed two abbreviated versions of the GCSS using nonparametric item response modeling and validated them. Results indicated that eight items provided maximal information about the gay community stress construct; these items were selected to form the eight-item GCSS. The eight-item GCSS reproduced the factor structure of the parent scale, and gay community stress scores obtained from it correlated with other identity-specific social stress constructs and mental health symptoms. Associations between gay community stress and mental health symptoms remained significant even after controlling for related identity-specific stressors, general life stress, and relevant demographics. A four-item version was also developed and assessed, showing good structural, convergent, criterion, and incremental validity and adequate reliability. The eight- and four-item versions of the GCSS offer efficient measures of gay community stress, an increasingly recognized source of stress for gay and bisexual men.

Multiple dimensions of stress vs. genetic effects on depression

Many psychiatric disorders including depression involve complex interactions of genetics and environmental stressors. Environmental influence is challenging to measure objectively and account for in genetic studies because the necessary large population samples in these studies involve individuals with varying cultures and life experiences, clouding genetic findings. In a unique population with relative sociocultural homogeneity and a narrower range of types of stress experiences, we quantitatively assessed multiple stress dimensions and measured their potential influence in biasing the heritability estimate of depression. We quantified depressive symptoms, major lifetime stressors, current perceived stress, and a culturally specific community stress measure in individuals with depression-related diagnoses and community controls in Old Order Amish and Mennonite populations. Results showed that lifetime stressors measured by lifetime stressor inventory (R2 = 0.06, p = 2 × 10−5) and current stress measured by Perceived Stress Scale (R2 = 0.13, p < 1 × 10−6) were both associated with current depressive symptoms quantified by Beck Depression Inventory in community controls, but current stress was the only measure associated with current depressive symptoms in individuals with a depression diagnosis, and to a greater degree (R2 = 0.41, p < 1 × 10−6). A novel, culturally specific community stress measure demonstrated internal reliability and was associated with current stress but was not significantly related to depression. Heritability (h2) for depression diagnosis (0.46 ± 0.14) and quantitative depression severity as measured by Beck Depression Inventory (0.45 ± 0.12) were significant, but h2 for depression diagnosis decreased to 0.25 ± 0.14 once stressors were accounted for in the model. This quantifies and demonstrates the importance of accounting for environmental influence in reducing phenotypic heterogeneity of depression and improving the power and replicability of genetic association findings that can be better translated to patient groups.

Risk From Within: Intraminority Gay Community Stress and Sexual Risk-Taking Among Sexual Minority Men

Background Sexual minority men remain highly impacted by the human immunodeficiency virus (HIV) with social stress being a clear predictor of their risk for infection. The past several decades of stress research regarding sexual minority men’s HIV-risk behaviors has almost exclusively focused on the influence of stress emanating from outside the gay community (e.g., stigma-related stress, or minority stress, such as heterosexist discrimination). However, recent evidence suggests that sexual minority men also face stress from within their own communities. Purpose We sought to examine whether stress from within the gay community, or intraminority gay community stress, might influence sexual minority men’s risk behaviors, including HIV-risk behaviors, over-and-above more commonly examined stressors affecting this risk. Methods We tested whether intraminority gay community stress was associated with sexual minority men’s HIV-risk behaviors in a large national survey of sexual minority men (Study 1), and experimentally tested intraminority gay community stress’s impact on behavioral risk-taking and attitudes toward condom use (Study 2). Results Self-reported exposure to intraminority gay community stress was positively associated with HIV-risk behaviors when accounting for the effects of several commonly examined minority stressors and general life stress (Study 1). Participants who were rejected from an online group of other sexual minority men evidenced greater risk-taking in a subsequent task and reported fewer benefits of condom use than participants who were accepted by the online group, when accounting for state affect (Study 2). Conclusions Sexual minority men’s experiences of stress and rejection stemming from their own community may be an important and overlooked predictor of HIV infection and transmission.
