A Preliminary Experimental Study of Minority Stress, Startle Reactivity, and Alcohol Use among Heavy Drinking Sexual Minority Young Adults

Whose Signals Are Being Amplified? Toward a More Equitable Clinical Psychophysiology

Research using psychophysiological methods holds great promise for refining clinical assessment, identifying risk factors, and informing treatment. Unfortunately, unique methodological features of existing approaches limit inclusive research participation and, consequently, generalizability. This brief overview and commentary provides a snapshot of the current state of representation in clinical psychophysiology, with a focus on the forms and consequences of ongoing exclusion of Black participants. We illustrate issues of inequity and exclusion that are unique to clinical psychophysiology, considering intersections among social constructions of Blackness and biased design of current technology used to measure electroencephalography, skin conductance, and other signals. We then highlight work by groups dedicated to quantifying and addressing these limitations. We discuss the need for reflection and input from a wider variety of stakeholders to develop and refine new technologies, given the risk of further widening disparities. Finally, we provide broad recommendations for clinical psychophysiology research.

Predictors of Empirically Derived Substance Use Patterns Among Sexual and Gender Minority Populations of a Rural Midwestern State

Purpose: The study purpose was to (1) identify latent classes of substance use behaviors among a sample of sexual and gender minority (SGM) adults living in a predominantly rural midwestern state and (2) determine the association between SGM-related discrimination and the empirically derived substance use classes. Methods: We conducted a latent class analysis on 494 responses to a state-wide survey, followed by a multinomial logistic regression to test predictors of class membership, including distal experiences of discrimination and sociodemographic variables. Results: A three-class model fit best and included (1) polysubstance use, (2) binge drinking, and (3) no/low use classes. In the adjusted model, polysubstance class membership was positively associated with cisgender male identity and negatively associated with being 60 years of age or older and college educated. Binge drinking class membership was negatively associated with bisexual/pansexual identity and non-White race/ethnicity. In contrast to hypothesized outcomes guided by the Minority Stress Model, experiences of discrimination were not associated with membership in substance-using classes. Likewise, bisexual/pansexual individuals were not more likely to be members of polysubstance use or binge drinking classes, despite published reports of greater risk of substance use. Conclusion: These contradictions warrant intersectional approaches to advance substance use research, which may provide important evidence for targeted prevention/treatment interventions, particularly among polysubstance users.

Differences by sex and gender in the association between minority stress and alcohol use among sexual and gender minority youth: A daily diary study

Rationale

Sexual and gender minority (SGM) youth consume more alcohol than their heterosexual, cisgender peers. The experience of minority stress is theorized to explain these disparities. Research often neglects the day-to-day variability in minority stress that SGM youth encounter and whether alcohol use is associated with daily experiences of minority stress. Further, there is heterogeneity in alcohol use among SGM youth. Sex assigned at birth and gender identity could potentially explain this heterogeneity.

Objective

Therefore, this study aimed to examine whether daily experiences of minority stress were associated with daily alcohol use among SGM youth and how these associations differed by sex assigned at birth and gender identity.

Methods

A 14-day daily diary study was conducted among 393 Dutch SGM youth (M age = 18.36 SD = 2.65).

Results

Results showed few significant associations between both mean levels of minority stress and daily experiences with minority stress with alcohol use. However, higher mean levels of prejudice events were associated with higher odds of daily alcohol use (OR = 7.01, 95% CI: 1.20–40.89). Daily experiences with identity concealment were associated with lower odds of daily alcohol use for males (OR = 0.72, 95% CI: 0.60–0.86), but not for females (OR = 1.11, 95% CI: 0.93–1.32). Further, for cisgender youth, daily experiences with prejudice events were associated with higher odds of alcohol use (OR = 1.99, 95% CI: 1.05–3.78), but this was not the case for gender minority youth (OR = 0.42, 95% CI: 0.15–1.18).

Conclusions

The findings showed few significant associations between minority stressors and alcohol use, but daily experiences of concealment and prejudice events were associated with daily alcohol use and these associations varied by sex assigned at birth and gender identity, respectively.
