    Recent advances in imaging have enabled the study of social rank, which refers generally to an individual’s social standing as either dominant or subordinate in a group, in relation to brain structure and function. From an evolutionary perspective, the mind is a modular structure from which various psychological traits and processes evolved in order to promote the success of the individual and the species. Gilbert (2000) argues that social rank theory explains responses reflecting such a system, which appears to have functional underpinnings linking limbic, prefrontal, and striatal structures (Levitan et al., 2000). Researchers argue tha

    Black adults experience high rates of overweight/obesity, which is linked to chronic diseases and is exacerbated by fast-food consumption. Anxiety sensitivity, a relative stable fear of anxiety-related sensations, has been linked to high caloric intake. Here, we examine whether anxiety sensitivity is associated with fast-food ordering habits within a convenience sample of black adults. Of 124 adults (79.4% women; Mage = 49.3±11.6; 84.8% overweight/obese), 107 (86.3%) reported eating from a fast-food restaurant in the last month. Participants completed the Anxiety Sensitivity-Index 3, which has a total score and physical, cognitive, and social concerns subscales. Investigator-generated items queried frequency of ordering “supersized” quantities of fast-food (e.g., cheeseburgers, fries), and healthy items (e.g., salads, oatmeal, yogurt), respectively, from “never” to “always.” Covariate-adjusted ordinal logistic regression models were used to assess relations between measures of interest. Anxiety sensitivity (total and physical concerns) was associated with greater odds of more frequently ordering supersized unhealthy fast-food; and anxiety sensitivity (total and cognitive concerns) was associated with lower odds of more frequently ordering healthy items from fast-food restaurants. Results suggest that adults with greater anxiety sensitivity may engage in fast-food ordering habits that can contribute to the overweight/obesity epidemic. Future studies should replicate results and determine the potential for anxiety sensitivity-reduction interventions to affect dietary choices that contribute to overweight/obesity

    Using the Orsmond and Cohen feasibility framework, the primary aim of this study was to assess the feasibility of the implementation of recruitment strategies, data collection procedures, and managerial resources needed to assess pro- and anti-inflammatory biomarkers from low-income, younger Hispanic adults. The secondary aim of this study was to describe the relationship between discrimination stress and inflammation as pilot work for future studies. Data were collected in a Houston-area community center from self-identifying Hispanic adults (ages 21–35) (August 2018). Inflammation was evaluated from blood samples, and interviewer-administered surveys in participants’ preferred language measured discrimination stress (Hispanic Stress Inventory-2 discrimination subscale). Spearman rank-order correlations evaluated the relationships between discrimination stress and inflammatory biomarkers. The recruitment strategies, data collection strategy, and the associated resources were evaluated and found to be feasible. While 50 participants consented to donate blood, five were too dehydrated for sample collection. Among the 45 participants [Mage = 28.9 (SD = 4.4), 17.8% U.S.-born, 42.2% 1.5 generation, 40% 1.0 generation], discrimination stress was negatively correlated with proinflammatory cytokine interleukin-8 (p \u3c 0.01). This study demonstrated feasibility using established benchmarks. The negative correlation between discrimination stress and interleukin-8 suggests discrimination stress may contribute to inflammatory dysregulation

    A large body of literature has substantiated the relationship between alcohol use and violent behaviors, but little consideration has been given to implicit interactions between the two. This study examines the implicit attitudes associated with alcoholic drinks and violent behaviors, and their relationship to explicit reports of problematic behaviors associated with alcohol use. The Go/No-Go Association Task (GNAT, Nosek & Banaji, 2001) was used to test the effect of distracters (noise) on implicit cognitions associated with alcoholic drinks and violent behaviors. Data was collected from 148 students enrolled in a Midwestern university. Irrespective of contextual distractions, participants consistently exhibited negative implicit cognitions associated with violent behaviors. However, context impacted the valence of cognitions associated with alcoholic beverages. Implicit cognitions associated with alcoholic beverages were negative when nonalcoholic beverages were used as distracters, but were positive when licit and illicit drugs were used as distracters. Implicit cognitions associated with alcoholic drinks were correlated with implicit cognitions associated with violent behaviors and explicit measures of problem drinking, problem drug-related behaviors, and measures of craving, to name a few. Evaluative context can have an effect on the expressed appraisal of implicit attitudes. Implications, limitations, and future directions for using the GNAT in addictions research are discussed

    The Association of Lesbian, Gay, and Bisexual Identity Facets with Smoking Dependence Motives

    Introduction: Lesbian, gay, and bisexual (LGB) adults have higher rates of smoking than heterosexual adults. LGB individuals face unique stressors, including challenges associated with having a LGB identity. The extent to which these unique stressors are related to dependence motives in LGB adult smokers, however, has not been previously explored. The current study was conducted to redress these gaps. Methods: Participants (N=52; Mage=42.8; 55.8% Black/African American) were recruited from the local community. Identity facets were measured by the Lesbian, Gay, and Bisexual Identity Scale (LGBIS). Dependence motives were measured by the Brief Wisconsin Inventory of Smoking Dependence Motives. Linear multiple regressions were calculated with the predictors of seven LGBIS subscales for primary and secondary dependence motives, respectively. Results: Primary dependence motives (core nicotine dependence features) were predicted by affirmation of LGB identity (β=.44). Secondary dependence motives (e.g., taste, cognitive/affective enhancement) were predicted by uncertainty of LGB identity (β=.43). Conclusions: LGB identity affirmation was associated with primary dependence motives, suggesting that a positive view of one’s sexual orientation is a risk factor for dependence. It may be that identity affirmation is related to stronger involvement with the LGB community, which has smoking-friendly norms. Identity uncertainty was associated with secondary dependence motives; this unique identity challenge may represent a stressor contributing to smoking dependence. Findings can help explain the higher rate of smoking in LGB populations and offer avenues to better tailor smoking cessation interventions.Educational Psychology, Department o

    The Relatinship Between Alcohol Consumption, Perceived Stress, and CRHR1 Genotype on the Hypothalamic-Pituitary-Adrenal Axis in Rural African Americans

    Objective: Rurally situated African Americans suffer from stress and drug-related health disparities. Unfortunately, research on potential mechanisms that underlie this public health problem have received limited focus in the scientific literature. This study investigated the effects of perceived stress, alcohol consumption, and genotype on the Hypothalamic-Pituitary-Adrenal (HPA) Axis. Method: A rural sample of African American emerging adults (n = 84) completed a battery of assessments and provided six samples of salivary cortisol at wakeup, 30 min post wakeup, 90 min post wakeup, 3:00 PM, 3:30 PM, and 4:30PM. Results: Participants with a TT genotype of the CRHR1 (rs4792887) gene tended to produce the most basal cortisol throughout the day while participants with a CC genotype produced the least amount. Increased levels of perceived stress or alcohol consumption were associated with a blunted cortisol awakening response (CAR). Moreover, the CAR was obliterated for participants who reported both higher stress and alcohol consumption. Conclusions: Perceived stress and alcohol consumption had a deleterious effect on the HPA-Axis. Furthermore, genotype predicted level of cortisol production throughout the day. These findings support the need to further investigate the relationship between stress dysregulation, drug-use vulnerability, and associated health disparities that affect this community

    Association of Problematic Alcohol Use and Food Insecurity among Homeless Men and Women

    Food insecurity results from unreliable access to affordable and nutritious food. Homeless adults are particularly vulnerable to both food insecurity and problematic alcohol use. The current study examined the link between problematic alcohol use and food insecurity among homeless adults. Participants (N = 528; 62.7% men; Mage = 43.6 ± 12.2) were recruited from homeless-serving agencies in Oklahoma City. Problematic alcohol use was measured using the Alcohol Quantity and Frequency Questionnaire and the Patient Health Questionnaire. The latter used DSM-IV diagnostic criteria to assess probable alcohol use dependence/abuse. Heavy drinking was considered >7 drinks (women) and >14 drinks (men) per week. Food insecurity was measured with the USDA Food Security Scale-Short Form. The link between alcohol problems and food insecurity was examined with logistic regression analyses controlling for sex, age, education, income, and months homeless. Overall, 28.4% of the sample had probable alcohol dependence, 25% were heavy drinkers, and 78.4% were food insecure. Probable alcohol dependence and heavy drinking were correlated at 0.53 (p < 0.001). Results indicated that heavy drinking (OR = 2.12, CI.95 = 1.21, 3.73) and probable alcohol dependence/abuse (OR = 2.72, CI.95 = 1.55, 4.77) were each associated with increased odds of food insecurity. Food insecurity and problematic alcohol use are major issues among homeless populations; this study suggests they are associated. Future research is needed to shed light on potential causal mechanisms and on whether alcohol may take precedence over eating or food purchases

    Mobile Intervention to Address Cannabis Use Disorder Among Black Adults: Protocol for a Randomized Controlled Trial

    BackgroundAfrican American or Black (hereafter referred to as Black) adults who use cannabis use it more frequently and are more likely to meet criteria for cannabis use disorder (CUD) than both White and Hispanic or Latin individuals. Black adults may be more apt to use cannabis to cope with distress, which constitutes a false safety behavior (FSB; a behavior designed to reduce psychological distress in the short term). Although FSB engagement can perpetuate the cycle of high rates of CUD among Black individuals, limited work has applied an FSB elimination treatment approach to Black adults with CUD, and no previous work has evaluated FSB reduction or elimination in the context of a culturally tailored and highly accessible treatment developed for Black individuals. ObjectiveThis study aims to develop and pilot-test a culturally tailored adaptive intervention that integrates FSB reduction or elimination skills for cannabis reduction or cessation among Black adults with probable CUD (Culturally Tailored-Mobile Integrated Cannabis and Anxiety Reduction Treatment [CT-MICART]). MethodsBlack adults with probable CUD (N=50) will complete a web-based screener, enrollment call, baseline assessment, 3 daily ecological momentary assessments (EMAs) for 6 weeks, and a follow-up self-report assessment and qualitative interview at 6 weeks after randomization. Participants will be randomized into 1 out of the 2 conditions after baseline assessment: (1) CT-MICART+EMAs for 6 weeks or (2) EMAs only for 6 weeks. ResultsThe enrollment started in June 2023 and ended in November 2023. Data analysis will be completed in March 2024. ConclusionsNo culturally tailored, evidence-based treatment currently caters to the specific needs of Black individuals with CUD. This study will lay the foundation for a new approach to CUD treatment among Black adults that is easily accessible and has the potential to overcome barriers to treatment and reduce practitioner burden in order to support Black individuals who use cannabis with probable CUD.
