Objective: This scoping review was to synthesize the rapidly accelerating literature on Indigenous peoples and medications for opioid use disorder (MOUD) and to identify barriers to implementation and sustainability. The article also addressed outcomes, perspectives, and suggestions for implementing culturally adapted MOUD programs.

Method: We conducted a scoping review of articles indexed in MEDLINE, APA PsycInfo, Scopus, and ERIC (through September 2024). Articles needed to include substantive information on an Indigenous population (in Canada, the United States, New Zealand, or Australia), include content on MOUD, and address the intersection of MOUD and Indigenous populations. Titles/abstracts were screened by two reviewers, followed by a full-text review and data extraction.

Results: Forty articles met inclusion criteria, organized under two primary categories: medication type (n = 18) and nonmedication specific (n = 22). Overall, Indigenous clients have a mixed degree of engagement, retention, and positive outcomes within methadone, buprenorphine, and injectable opioid agonist treatment programs. Promising findings emerged for MOUD programs targeting Indigenous youth and that incorporate comprehensive cultural and health frameworks. Across MOUD types, Indigenous clients had consistently lower rates of treatment access and retention than did non-Indigenous clients.

Conclusions: The findings emphasize the importance of aligning MOUD programs with Indigenous cultural frameworks and involving Indigenous consultation at all stages. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Objective: People with HIV (PWH) smoke at higher rates than people without HIV (PWOH). Alternative reinforcers, or behaviors that replace (substitute reinforcers) or maintain (complementary reinforcers) smoking, are associated with smoking outcomes but have not been studied among PWH. This observational study assessed whether alternative reinforcers changed during a quit attempt among PWH and PWOH and whether the associations differed between groups.

Method: The parent study included 274 participants (93 PWH and 181 PWOH) who sought treatment for smoking cessation in a 12-week program. The present analyses were limited to 173 (73 PWH and 100 PWOH) study completers. The primary outcomes were changes in substitute and complementary reinforcers at the end of treatment (EOT; week 12) measured using the Pleasant Events Schedule. We performed linear regressions in the overall sample and then stratified by HIV status for each alternative reinforcer. The time (baseline; week 0 vs. EOT) by smoking status at EOT (abstinent vs. nonabstinent) interaction was tested.

Results: Self-reported substitute reinforcers increased significantly over time, but this was not associated with smoking or HIV status (ps > .05). Self-reported complementary reinforcers decreased over time, and this decline was greater among abstinent compared to nonabstinent PWH (b = -13.15, z = -2.04, 95% confidence interval [-25.77, -0.53], p = .04).

Conclusions: Declines in complementary reinforcers were associated with smoking cessation outcomes among PWH. These findings partially support results from prior literature, suggesting that addressing complementary reinforcers during smoking cessation treatment may be crucial in improving quit rates among PWH.

Objective: Alcohol use is common in older adults and linked to poor health and aging outcomes. Studies have demonstrated genetic and environmental contributions to the quantity of alcohol consumption in mid-to-late life, but less is known about whether these influences are moderated by sociodemographic factors such as age, sex, and educational attainment. This study sought to better understand sociodemographic trends in alcohol consumption across the second half of the life course and their underlying genetic and environmental influences.

Method: Primary analyses were based on 64,140 middle-aged or older adult twins (40-102 years) from 14 studies in the Interplay of Genes and Environment Across Multiple Studies consortium. We harmonized a measure of weekly alcohol consumption (in grams of ethanol per week) across all studies.

Results: Older age was associated with lower alcohol consumption, primarily for adults over age 75, for individuals with higher education, and for males. Trends were similar across birth cohorts and after excluding current abstainers. At mean age 56, alcohol use was moderately heritable in females (.34, 95% CI [.26, .41]) and more heritable in males (.42, 95% CI [.38, .45]). Heritability was lower in older aged adults and in females with higher education.

Conclusions: This study represents the largest twin study of alcohol consumption in middle-aged and older adults. Results highlight that genetic and environmental factors influence alcohol consumption differently across age, sex, and educational attainment and that intervention efforts may need to be tailored based on individuals' backgrounds.

Objective: Sexual and gender minorities (SGM) are at elevated risk for alcohol and cannabis use disorders compared to cisgender, heterosexual individuals. This has been attributed to the unique stressors that SGM experience (SGM stress); however, recent studies have found mixed evidence for a link between SGM stress and substance use. The present study tests an integrated theoretical model derived from minority stress theory and the multistage model of substance use to explain these mixed findings.

Method: We used data from a 30-day ecological momentary assessment study of substance use among 109 SGM older adults (50+) to examine whether event-level associations between enacted stigma and alcohol and cannabis use, quantity consumed, and consequences are dependent on an individual's typical pattern of substance use (e.g., frequency, coping motives, and substance use disorder symptoms).

Results: Findings indicate that, at the event level, enacted stigma was associated with increased likelihood of alcohol use among those who had a probable alcohol use disorder. Further, SGM with more alcohol use disorder/cannabis use disorder symptoms and who used alcohol to cope were more likely to engage in heavier cannabis use and experienced more alcohol consequences when they experienced enacted stigma. However, several other moderations were not significant, contrary to hypotheses.

Conclusions: Findings provide partial support for an integrated theoretical model incorporating minority stress theory and the multistage model of substance use. Findings suggest that alcohol and cannabis use disorder interventions for SGM would benefit from addressing minority stress. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Objective: Previous research with U.S. Hispanic college students tends to find that higher levels of acculturation are associated with elevated alcohol use and that these effects are likely to be stronger for women than men. It is now important to consider the extent to which these associations remain once theoretically proximal predictors of alcohol use (e.g., drinking motives) are accounted for in multivariate models. Thus, we examined how multiple domains of acculturation were associated with alcohol use, high intensity drinking, and negative alcohol consequences, and whether direct associations and potential gender moderation of these relationships remained after drinking motives were included in the model.

Method: Hispanic undergraduates from 12 universities who reported current alcohol use (n = 1,131; M_age = 20.47, SD = 1.85, range = 18-25) completed self-report questionnaires online.

Results: After accounting for demographic variables and drinking motives, U.S. cultural practices were negatively associated with alcohol use, and ethnic identity was negatively associated with high intensity drinking. Heritage cultural practices were positively associated with high intensity drinking among women only. Finally, enhancement motives were positively associated with alcohol use and high intensity drinking, while social and coping-depression motives were positively related to negative alcohol consequences, even after accounting for demographic variables and multiple acculturation domains.

Conclusions: The present findings paint a nuanced picture of the effects of ethnic identity and engagement with cultural practices on drinking behaviors, particularly among Hispanic college women. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Objective: Suicide is a leading cause of preventable death. Problematic alcohol use and service in the U.S. military confer elevated risk for suicide, yet it is unknown whether their combination further heightens the risk. Extant literature is circumscribed to veterans enrolled in Veterans Affairs care, those with diagnosed alcohol use disorder, or suicide mortality, resulting in notable literature gaps on non-Veterans Affairs-enrolled veterans, nondiagnostic problematic drinking behaviors, and premortality suicide risk.

Method: To address these gaps, this study included U.S. adults who participated in the 2015-2020 National Survey on Drug Use and Health, representing 236,723,876 adults. Suicide ideation, planning, and attempt; veteran status; binge drinking, heavy drinking, and demographics were extracted from the cross-sectional self-report survey. Multivariable logistic regression examined suicide ideation, planning, and attempt as a function of veteran status and drinking variables after accounting for relevant demographics.

Results: Veterans and nonveterans who reported binge or heavy alcohol use were more likely to report suicide risk. Veterans who engaged in binge drinking episodes were 33% more likely than nonveterans to report any suicide risk. Veteran males who reported binge alcohol use were 38% more likely than nonveteran males to report any suicide outcome. Veterans who reported binge drinking were 72% more likely to report suicide planning without an attempt relative to nonveterans.

Conclusions: Efforts to reduce suicide planning among veterans reporting binge drinking are critically needed and present one avenue for reducing the likelihood of a suicide attempt or actual death by suicide. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Objective: This study used ecological momentary assessment to investigate the association between unplanned drinking and alcohol-impaired driving (AID) cognitions and behavior among adults.

Method: Adults (N = 125) completed 6 weeks of morning and evening ecological momentary assessment surveys assessing plans to drink later that night, driving behavior, and AID cognitions. Mixed-effects models with moments (Level 1) nested within days (Level 2) within person (Level 3) were used to test the effect of planned (vs. unplanned) drinking intentions on perceived danger of AID and willingness to engage in AID. A separate two-level model (days nested within person) tested planned (vs. unplanned) drinking on AID behavior. A novel breath alcohol concentration biosensor accounted for alcohol consumption in all models.

Results: Unplanned drinking episodes were associated with lower perceived danger of AID, increased willingness to engage in AID, and higher odds of engaging in AID, compared to planned drinking episodes. Findings were held after controlling for alcohol consumption measured by breath alcohol concentration biosensors.

Conclusions: Findings suggest that unplanned drinking intentions confer risk for AID-a behavior requiring significant preparation and planning to avoid. Findings highlight the need for future research investigating unplanned drinking's effect on other negative consequences requiring preparation and planning. Additionally, findings highlight the need for targeted interventions and policies to reduce unplanned drinking to prevent AID and improve public health outcomes among adults.

Objective: The proliferation of gambling advertising has raised concerns about its effects on gambling behavior, particularly among vulnerable populations such as highest risk gamblers. This study examines the influence of gambling advertising on attitudes and intentions to gamble on a large sample of gamblers in France.

Method: We used an online questionnaire in a cross-sectional design, with data collected between February 15 and April 30, 2021. Participants were recruited through a single recruitment channel, namely the client mailing list of the Française des Jeux, resulting in a final sample consisting of 1,334 participants (62% male, 38% female, < 1% other) with a mean age of 41.37 years (SD = 15.07). Participants completed validated questionnaires, including the Canadian Problem Gambling Index, advertisement recall, measures of impulsivity, and cognitive distortions. Exposure to responsible-gambling messages was recorded descriptively and not manipulated.

Results: Results indicate that exposure to gambling advertising was significantly associated with more positive participants' attitudes toward gambling and their intentions to engage in gambling activities. Highest risk gamblers were more susceptible to the influence of advertising, showing higher recall of advertisements and greater likelihood of gambling after exposure.

Conclusions: The study highlights the urgent need for regulatory action to limit exposure of vulnerable populations to gambling advertising and formulate strategies to mitigate gambling-related harm. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Objective: Individual differences in how well people are able to endure unwanted emotional states, or distress tolerance, may impact whether and how much people drink in response to negative affect, as well as the degree to which their negative affect declines after drinking. We examined trait distress tolerance as a moderator of the daily life association of negative affect with subsequent alcohol use, and vice versa.

Method: Participants (N = 41) completed four assessments per day for 60 days. We examined whether distress tolerance moderates the relationship between cumulative negative affect so far that day and any subsequent alcohol use (vs. no use, Model 1; total drinks consumed, Model 2), as well as the cumulative number of drinks consumed and subsequent negative affect (Model 3).

Results: Greater cumulative negative affect was associated with reporting greater cumulative alcohol quantities (Model 2), though not with any alcohol use (Model 1). Distress tolerance did not moderate these relationships. However, distress tolerance significantly moderated the association of cumulative drinks and subsequent negative affect. Simple slopes indicated that consuming more alcohol was associated with greater reductions in negative affect in participants with low distress tolerance.

Conclusions: Findings suggest a complicated relationship between negative affect, distress tolerance, and alcohol use. Greater reductions in negative affect following alcohol use in people with low distress tolerance may potentially place them at greater risk of developing alcohol use disorder.

Objective: Cannabis use is common among U.S. military veterans, particularly those experiencing posttraumatic stress disorder (PTSD), poor sleep, and elevated stress. While often used to self-manage these symptoms, the impact of cannabis on day-to-day symptomology remains unclear. This study examined the daily associations among cannabis use, PTSD symptoms, perceived stress, and sleep quality using intensive longitudinal data.

Method: Seventy-four recently separated U.S. veterans (age = 33.5 years; 80% male; 61% non-Hispanic White) who endorsed past-month cannabis use and elevated PTSD symptoms completed a 3-month daily diary study. Participants provided 4,307 person-days of data via a mobile app. Measures included daily cannabis use (hours high), PTSD symptoms, perceived stress, and sleep quality. Dynamic structural equation modeling (DSEM) was used to estimate within-person lagged and same-day associations, adjusting for relevant covariates.

Results: Day-to-day analyses revealed that elevated PTSD symptoms and poor sleep quality each predicted greater perceived stress the following day. Greater number of hours high was associated with less perceived stress the following day. Perceived stress, in turn, predicted both higher PTSD symptoms and poorer sleep quality. In post hoc analysis, stress emerged as a significant mechanism of change in the day-to-day lagged model. In particular, we show greater cannabis use is linked to improved sleep and PTSD symptoms through lower perceived stress.

Conclusion: Cannabis may offer temporary relief and appears to interrupt the day-to-day cycle linking PTSD, stress, and poor sleep. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
