In this study, we tested expectancy of alcohol analgesia (EAA) as a moderator of subjective pain relief following oral alcohol challenge in individuals with and without chronic orofacial pain. Social drinkers (<i>N</i> = 48; 19 chronic pain; 29 pain-free controls) completed two testing sessions: alcohol administration (BrAC: 0.08 g/dL) and placebo. Alcohol expectancy (AE) was assessed using the EAA questionnaire and two 100-mm Visual Analogue Scales (VASs) regarding strength of belief that alcohol provides pain relief (AE VAS 1) or reduces pain sensitivity (AE VAS 2). Participants completed quantitative sensory testing (QST) involving application of pressure to the masseter insertion. Pain threshold (lbf; three repetitions) and pain intensity (4, 5, and 6 lbf; three repetitions each; 100-mm VAS) were collected. After each stimulus, participants rated perceived pain relief due to consumption of the study beverage (0-100 VAS). Higher EAA and AE VAS 1 ratings were associated with stronger perceived relief in the alcohol, but not placebo, condition. However, expectancy specifically related to reduction in pain sensitivity (AE VAS 2) was not associated with relief. Additionally, changes in pain threshold and intensity were not significantly correlated with perceived relief. Taken together, results suggest expectancy that alcohol provides pain relief is an important determinant of its negative reinforcing effects. Future studies should investigate challenging these expectancies as a means of reducing alcohol-related risk in people with pain.

The present cross-sectional study served to evaluate the indirect effects of depressive and anxiety symptoms in terms of relations between racial/ethnic stress reactivity and cigarette dependence, severity of problems when trying to quit, and perceived barriers for quitting among Hispanic persons who smoke in the United States. Participants included 329 Hispanic adults who smoked cigarettes daily (<i>M</i>_age = 35.5 years; <i>SD</i> = 8.67; 37.4% female). Results indicated that depressive symptoms exerted a statistically significant indirect effect in the association between negative emotional reactivity to racial/ethnic stress and cigarette dependence and severity of problems when trying to quit, whereas anxiety symptoms maintained an indirect effect for perceived barriers for smoking cessation. The current findings help characterize the intricacies by which negative emotional reactivity to racial/ethnic stress is related to smoking behavior and beliefs among Hispanic persons who smoke.

The present study is a pre-post, randomized, open-label trial that aimed to examine the effects of oral cannabidiol (CBD) isolate for alleviating MRS. Participants were assigned randomly to one of two open-label dosing groups of CBD softgels (160 mg twice a day, BID, <i>n</i> = 17; 320 mg BID, <i>n</i> = 16) and completed a 1-month baseline period. Following baseline, participants were instructed to consume CBD starting the first day they believed they experienced symptoms each month and to take their assigned dose daily for 5 consecutive days for three CBD-consumption months. We examined differences in MRS and related outcomes between baseline and 3 months of CBD consumption. Results revealed reductions (in both dosing groups) in MRS, irritability, anxiety, global impression of change, stress, and subjective severity scores when comparing baseline to all 3 months of CBD consumption. Depression scores did not change in either dosing group. Findings suggest that CBD may have the potential for managing MRS. Importantly, changes in symptoms appeared in the first month of CBD consumption and persisted over the 3 consumption months. Further research is warranted comparing the effects of CBD to placebo (a limitation of the study) and examining the potential to optimize CBD consumption for reducing MRS (e.g., combining CBD with terpenes; varying routes and timing of administration).

Protective behavioral strategies (PBS) are behaviors for reducing alcohol use and/or problems and are negatively associated with alcohol misuse among college students. Studies suggest PBS are used more often and/or more effectively by female individuals. Additionally, examinations specifically between Black and White students have yielded mixed findings and are typically underpowered. Scant studies have investigated the intersectionality between race and gender or examined perceived effectiveness of PBS use related to alcohol outcomes. The current cross-sectional study examined if (a) race, (b) gender, and (c) their interaction moderate the associations between perceived effectiveness of PBS use on PBS use (<i>a</i> path) and between PBS use on alcohol outcomes (i.e., alcohol quantity, peak drinks, and problems; <i>b</i> path). A sample size of <i>N</i> = 528 college drinkers ages 18-24 years old (<i>M</i>_age = 19.85; 52.5%, Black, 40.3% White) completed an online survey and were used for analyses. A series of moderated mediation models were conducted. Race did not moderate the <i>a</i> or <i>b</i> paths. The positive association for the a path as well as the indirect effect of PBS perceived effectiveness on lower alcohol outcomes through PBS use were stronger for female students than male students. The intersectionality examination indicated a stronger association between more PBS use and lower consumption, specifically for White male students, and lower problems for Black female students. More attention is needed toward considering intersectionality when identifying at-risk groups and tailoring alcohol intervention efforts.

The ANA is a framework for assessing individual variability within AUD across three domains corresponding to the proposed stages of the addiction cycle: reward (binge-intoxication stage), negative emotionality (withdrawal-negative affect stage), and cognitive control (preoccupation-anticipation stage). Recent work has evaluated the ANA's three-factor structure and construct validity, primarily in treatment-seekers with AUD. We extended this research by examining the factor structure, bias across alcohol use severity, longitudinal invariance, and concurrent and predictive validity of a novel assessment of the ANA domains in adults with past 12-month regular (10 + alcohol units/week) alcohol use. Participants recruited from Prolific (<i>N</i> = 732), a crowdsourced data collection platform, completed various self-report measures. A test-retest subsample (<i>n</i> = 234) completed these measures 30 days later. Split-half exploratory factor analysis and confirmatory factor analysis supported the three-factor structure of the ANA. The overall factor structure was invariant across 30 days. Concurrently and prospectively, ANA domains demonstrated convergent validity concerning theoretically aligned alcohol-related, psychological, and personality measures. However, there was evidence of poor discriminant validity, and several cognitive control and reward items demonstrated bias across alcohol use severity. Future research is needed to improve the measurement of ANA domains using multimodal indicators, examine longitudinal changes in domains and their relationship with alcohol use severity, characterize phenotypic subgroups based on relative levels of domains, and compare the utility of the ANA with other proposed frameworks for measuring AUD heterogeneity.
