Objective: Alcohol misuse is common among women who have experienced sexual violence and is often attributed to the self-medication model of alcohol use to alleviate posttraumatic stress disorder (PTSD) symptoms. Despite the proximal theorized role of PTSD symptoms, less attention has been given to daily associations between PTSD symptoms, trauma-related drinking to cope (TRD) motives, and ensuing alcohol use by survivors. Moreover, despite indications that poor sleep impacts affective functioning and may exacerbate daily PTSD symptoms, the role of sleep duration and quality in drinking to cope with PTSD symptoms is not well understood. This study examined an integrated model testing whether shorter sleep duration and poorer sleep quality predict greater daily PTSD symptoms and, in turn, greater alcohol use later that day through TRD motives.

Method: Participants were 82 cisgender women (M_age = 22.8, 73.2% White, 13.4% Hispanic/Latina, 56.1% heterosexual, 30.5% bisexual) who had experienced sexual violence. Participants completed ecological momentary assessment measures and wore actigraphs for 3 weeks.

Results: Contrary to hypotheses, shorter-than-usual sleep duration did not predict greater alcohol use quantity via daily PTSD symptoms and TRD motives. However, poorer-than-usual sleep quality predicted greater PTSD symptoms that day, which in turn predicted greater same-day TRD motives.

Conclusions: Findings underscore the importance of sleep quality in heightened PTSD symptoms but suggest survivors did not drink more to alleviate trauma-related distress. Future research should examine other drinking motives among survivors to inform proximal interventions to prevent alcohol misuse. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Objective: Egocentric social network analyses show that drinking habits of college students' friends predict personal alcohol consumption. To date, most of this research focused on between-person, cross-sectional, or long-term longitudinal designs to evaluate these effects. This study used intensive longitudinal methods to examine episode-specific effects of social networks (network drinking, network composition) on college students' drinking, comparing within-person and between-person effects on individual episodic drinking, and highlighted social network characteristics that might be targeted for intervention.

Method: College students (N = 1,151, 54% female, M_age = 19.26, 81% White) identified their ego network: five close alters (e.g., friends, family) whom they met frequently. For 30 days using an internet-based diary, participants reported their daily drinking levels, indicated whether they met with each alter the previous night, and reported how many drinks each alter consumed.

Results: Two-part multilevel models were used to examine participant drinking. At the within-person level, when a higher proportion of a participant's ego network drank and when network total drinks were higher than average, the odds that a participant drank were significantly increased, and if they did drink, they consumed more alcoholic drinks than usual. Participants were more likely to drink on days when their network was comprised of more friends and more opposite-gender alters.

Conclusions: Findings provide preliminary evidence that daily network drinking appears to influence drinking patterns and quantities among students. Such information could be used within ecological momentary interventions to prevent harmful drinking patterns such as heavy drinking episodes and incapacitation.

Objective: Alcohol outcome expectancies (AOEs), formed in early childhood, are correlates of future alcohol consumption and related problems. Social-cognitive theories suggest that AOEs become activated in specific social and physical location contexts. Prior research, primarily among university students, has aimed to identify situational influences on specific AOEs, as indexed by reports of AOEs in hypothetical drinking scenarios. This study aims to deepen understanding of AOE activation in real-world settings by examining social and physical situational correlates of AOE activation among adolescents ages 15-17 in daily life.

Method: Adolescents (evaluable n = 102) reporting any drinking in the past month completed smartphone reports for 24 days. Adolescents indicated their social setting (e.g., solitary, peers, family), physical location (e.g., home, friend's place, elsewhere), and strength of AOEs (tension reduction, enhancement, sociability) just prior to drinking in daily life.

Results: Adolescents' AOE activation prior to drinking was associated with their immediate social context and physical location. Specifically, drinking with peers present was associated with higher ratings of enhancement and sociability AOEs. In contrast, drinking with family members present and drinking at home were associated with lower ratings of enhancement and sociability AOEs.

Conclusions: Our findings provide new information about social-contextual correlates of specific AOE domains in naturalistic settings among adolescents. Identifying situational relations with AOE activation in daily life is important to build social-cognitive models of alcohol-consumption behavior, particularly during adolescence as drinking experiences broaden.

Objective: Substance use problems peak in emerging adulthood and often co-occur with other psychiatric disorders. Developmentally tailored services are critical to reduce harms, promote recovery, and prevent persistence or exacerbation. The Young Adult Substance Use Program is an evidence-informed outpatient program for 17- to 25-year-olds that aligns with recent frameworks and principles for the treatment of substance use disorders among youth. This article provides (1) an overview of the program's evolution and (2) an evaluation of (a) recruitment, retention, and engagement; (b) clinical characteristics; and (c) treatment outcomes.

Method: Data come from the Young Adult Substance Use Program measurement-based care assessments and clinical chart reviews. A series of descriptive statistics and multilevel linear regressions were performed.

Results: Between February 2021 and May 2024, 339 young adults attended an intake, 263 fully enrolled (78%), and 122 (51%) completed the core components of the program (∼74% attendance). Of those completed or discharged (n = 230), 49% attended groups, 47% received a specialized consult, and 20% received a new medication. Patients were most commonly seeking treatment for alcohol (61%) and/or cannabis (60%) use, with near universal (95%) co-occurring mental health problems. Statistically significant (ps < .001) and clinically important (per minimal clinically important differences) changes were present for substance use, depression, anxiety, posttraumatic stress disorder symptoms, and quality of life. Approximately 80% reported a clinically important improvement by ∼12 weeks, although persistent clinical elevations were nonetheless present.

Conclusions: Overall, the Young Adult Substance Use Program is an example of an effective evidence-informed developmentally tailored and iteratively refined pragmatic outpatient young adult substance use program. Challenges, lessons learned, and future directions are discussed. (PsycInfo Database Record (c) 2026 APA, all rights reserved).

Objective: Substance use disorders frequently co-occur with internalizing disorders, such as depression and anxiety, particularly among emerging adults in treatment. While a growing literature has examined bidirectional associations between internalizing symptoms and substance use, findings remain mixed. The present study investigated whether social recovery capital (SRC) mediated bidirectional internalizing symptoms and substance use behaviors associations.

Method: Emerging adults (N = 302, 74% male sex assigned at birth, 95% White) were recruited from a residential substance use treatment facility and assessed at treatment baseline, 1-, 3-, 6-, and 12-month follow-ups (71% retention rate at the 12-month follow-up). Latent growth curve models with structured residuals, which disaggregate between- (i.e., growth processes) and within-person effects (i.e., cross-sectional and lagged associations), examined reciprocal associations between internalizing symptoms, SRC, and substance use outcomes.

Results: Results indicated that SRC and percent days abstinent increased over time, while internalizing symptoms decreased. Substance use consequences initially decreased but increased after the 3-month follow-up. At the within-person level, there was no support for the central hypothesis that SRC would mediate internalizing symptom-substance use associations. Greater internalizing symptoms were contemporaneously associated with higher substance use consequences. More SRC was contemporaneously associated with higher percent days abstinent and lower internalizing symptoms.

Conclusions: Contemporaneous associations between more SRC and lower internalizing symptoms and greater percent days abstinent suggest SRC may facilitate reductions of co-occurring substance use and internalizing symptoms. Future studies should explore alternative timescales and use more comprehensive measures of SRC. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Objective: The "illusion of control" is a dominant cognitive illusion in disordered gambling, but its role in shaping irrational gambling beliefs has been questioned by recent null experimental findings. Here, we aimed to test this recent work, in a preregistered Bayesian framework, by additionally correlating the dependent variable (nonuniform probabilistic beliefs) with self-reported gambling behavior and by exploring "passive superstition" as an alternative driver of these irrational gambling beliefs.

Method: A between-participants online experiment involving three boxes, one of which a $1 prize was randomly assigned to (N = 3,064; 49.1% males, 49.5% females, 1.4% other; M_age = 42.5 years). Participants estimated the likelihood of each box winning, with any estimates outside the 33%-34% interval categorized as irrational "nonuniform" probabilistic beliefs. "Preselection" participants gave estimates prior to box selection, "post-no-choice" participants had their box randomly selected, and participants in the treatment "postchoice" condition selected their own box. Whether participants gambled within the past 12 months (gambling status), Problem Gambling Severity Index (PGSI) score, and passive superstition scores were used as additional predictors.

Results: Comparing postchoice participants with post-no-choice participants (95% CI [0.80, 1.22]) and comparing postchoice with preselection participants (95% CI [0.88, 1.34]) yielded substantial support for a null effect. Gambling status supported substantial evidence for a null effect (95% CI [0.92, 1.30]), whereas higher PGSI (95% CI [1.08, 1.13]) and higher passive superstition scores (95% CI [1.08, 1.10]) overwhelmingly predicted our outcome.

Conclusions: Active choice elements in illusions of control may have been overemphasized in irrational gambling beliefs compared to passive superstitions. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Objective: The aim of the present study was to investigate the moderating role of racial-ethnic identity in the relation between emotion dysregulation and alcohol use and related harms among Asian Americans.

Method: An adult sample of Asian Americans (N = 105, 67.6% women) participated in a study examining emotional experiences across different racial and ethnic groups that assessed emotion dysregulation (Difficulties With Emotion Regulation; Difficulties With Emotion Regulation-Positive), alcohol use and related harms (Alcohol Use Disorder Identification Test), and ethnic-racial identity (Ethnic Identity Scale).

Results: Negative and positive emotion dysregulation were both significantly positively associated with alcohol use and related harms. A series of moderation analyses revealed that different dimensions of ethnic-racial identity moderated this relationship. Negative emotion dysregulation was significantly positively associated with alcohol use and related harms at lower levels of ethnic-racial identity Affirmation, and positive emotion dysregulation was significantly positively associated with alcohol use and related harms at higher levels of ethnic-racial identity Resolution.

Conclusions: This study is the first to test the moderating role of ethnic-racial identity in the associations between negative and positive emotion dysregulation and alcohol use and related harms among Asian Americans. Results of this study suggest that emotion dysregulation may play a key role in the maintenance of alcohol use and related harms among Asian Americans. Findings also suggest that an assessment of ethnic-racial identity may help identify Asian Americans who are most likely to benefit from interventions targeting negative and positive emotion dysregulation.

Objective: Although Black/African American (hereinafter Black) adults who smoke are a tobacco disparities population in the United States, little systematic research has sought to explicate how differences in the distinct experience of race-related threat are associated with established and clinically important smoking processes in one overarching model. The present investigation sought to bridge this gap and test perceived racial/ethnic discrimination and racial trauma in the context of one another regarding an array of processes involved in the maintenance and relapse of smoking behavior.

Method: Participants included 517 Black individuals who smoked cigarettes daily (≥ 5; M_age = 45.07, SD = 14.72, 51.5% identified as female).

Results: Results indicated that in adjusted models, perceived racial/ethnic discrimination and racial trauma were each associated with an increased risk of more severe problems when quitting smoking as well as somatic symptoms and harmful consequences in smoking abstinence expectancies. For perceived barriers to quitting and negative mood abstinence expectancies, only racial trauma exerted a statistically significant main effect. In contrast, there was a statistically significant main effect only for perceived racial/ethnic discrimination for positive smoking abstinence expectancies, such that greater perceived racial/ethnic discrimination was associated with less positive beliefs about the consequences of abstinence (e.g., positive affect).

Conclusion: Overall, the present investigation indicated that both perceived racial/ethnic discrimination and racial trauma were relatively consistent and impactful explanatory variables for several clinically significant smoking processes, even in the context of one another, among Black adults who smoke in the United States.

Objective: Research on the patterns and correlates of cannabis use suggests a disproportionately higher use incidence across Indigenous populations in Canada and the United States. As cannabis use is related to several deleterious social and behavioral consequences for which Indigenous Peoples are disproportionately vulnerable, it is a public health concern. We gathered and organized the extant research on cannabis use among Indigenous groups to describe emergent themes and future research areas.

Method: We conducted a scoping review of articles published between 2005 and February 2020 on Indigenous populations and cannabis use in Canada and the United States. We screened 1,934 articles indexed through APA PsycInfo, Scopus, and Medline, 152 of which were systematically coded and analyzed.

Results: Most studies focused on the prevalence and patterns of cannabis use initiation, followed by protective and risk factors, correlations of cannabis use and other substance use, correlations of cannabis with mental health diagnoses and with other health consequences, interventions for cannabis use, and cannabis legalization issues. Most articles focused on youth, were analyzed quantitatively, and discussed cannabis use in the context of general substance use.

Conclusions: Future research should explore culturally appropriate intervention programs and the impact of cannabis legalization issues. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Objective: This study examined moderating effects of family warmth on relationships between positive and negative affect and alcohol and cannabis use among American Indian (AI) youth.

Method: Participants were 5,831 AI students (seventh-12th grade) surveyed during the 2021 and 2022 school years. Students completed measures of positive and negative affect, family warmth, and past year alcohol and cannabis use. Multigroup and latent moderated structural equation modeling models tested hypothesized main and interactive effects of hypothesized relationships and explored moderation by sex.

Results: Family warmth and negative affect, but not positive affect, related significantly to alcohol use; all three predictors related significantly to cannabis use. Family warmth did not moderate associations between negative affect and either substance in the overall sample, nor the association of positive affect to alcohol use. However, family warmth moderated associations between positive affect and cannabis, with family warmth bolstering protective effects of positive affect. Female youth were less likely than male youth to use alcohol with increasing levels of warmth. Furthermore, compounding protective effects of family warmth and positive affect on cannabis use were stronger among female compared to male youth.

Conclusions: Several factors may explain the lack of a buffering effect of family warmth on the relationship between negative affect and substance use, including the use of a general affect measure rather than individual measures of depression and anxiety. Nevertheless, these findings suggest substance use interventions should consider the compounding effects of family warmth and positive affect, particularly among female AI youth.
