Objective: Prescription stimulant misuse (PSM) is prevalent among young adults, particularly college students. This study utilized structural equation modeling to examine differences in alcohol use, cannabis use, and alcohol consequences across PSM groups, (no use, appropriate use, medical misuse [i.e., not using one's own prescription as directed], and nonmedical misuse [i.e., using prescription stimulants not prescribed to oneself]) while controlling for psychological factors and other prescription drug use.

Method: Participants (N = 1,692, M_age = 19.1, 52.5% male, 70.5% White, 19.5% Hispanic/Latinx) were undergraduates who completed self-reported measures of prescription drug use, alcohol use, cannabis use, alcohol consequences (Brief Young Adult Alcohol Consequences Questionnaire), impulsivity (Short UPPS-P Impulsive Behavior Scale), and internalizing symptoms (Depression Anxiety and Stress Scales-21 [DASS-21]).

Results: Compared to no stimulant use, nonmedical stimulant misuse was associated with higher alcohol use (Wald χ² = 7.288, p = .007, d = 0.275) and cannabis use (Wald χ² = 25.491, p < .001, d = 0.444). Compared to appropriate use, nonmedical misuse was also associated with higher alcohol use (Wald χ² = 4.928, p = .026, d = 0.271) and cannabis use (Wald χ² = 8.215, p = .004, d = 0.349). Medical misuse was linked to greater cannabis use compared to nonuse (Wald χ² = 6.488, p = .011, d = 0.375), but not to alcohol use or consequences.

Conclusions: Nonmedical misuse was associated with higher alcohol and cannabis use, while medical misuse was more specifically linked to cannabis use. These findings support tailored interventions addressing unique misuse subtypes and substance use patterns. Future research should explore motivational and contextual factors.

Objective: Hazardous drinking and posttraumatic stress disorder (PTSD) are both highly prevalent and frequently comorbid conditions that result in more severe outcomes than either individual condition. It is therefore a priority to identify malleable treatment mechanisms that may underlie the hazardous drinking-PTSD comorbidity to inform evidence-based intervention efforts. Distress tolerance (DT), or the perceived ability to withstand negative affect states, is theoretically relevant to both hazardous drinking and PTSD symptoms. DT is relatively stable, but recent work indicates that it also maintains statelike qualities. Past work has not examined state DT as it relates to PTSD symptoms and comorbid hazardous drinking.

Method: The present study employed a national sample of adults with PTSD symptoms who endorsed hazardous alcohol use (N = 85; 71.8% female). Multilevel structural equation modeling (MSEM) was used to investigate the following aims using ecological momentary assessment over a 21-day period: examine whether lower state DT mediates the association between PTSD symptoms at baseline and latent variables of (a) alcohol use motivation (i.e., coping motives, craving, intention to drink) and (b) hazardous drinking behavior (i.e., consumption, drink recency, negative consequences).

Results: A statistically significant indirect effect was observed such that higher baseline PTSD severity was associated with greater alcohol use motivation via lower state DT; however, this indirect effect was not significant for the model examining hazardous drinking behavior.

Conclusions: Results underscore the importance of assessing state DT in clinical interventions that support individuals managing PTSD symptoms and the craving, intention, and motivation to drink due to these symptoms as they navigate momentary challenges to engage with or avoid distress.

Objective: Compulsive and addictive behaviors represent a growing public health concern, driven by the proliferation of digital technologies and evolving diagnostic classifications. This study aimed to map the global trajectory, collaborative networks, and conceptual structure of research on compulsivity and impulse control in nonsubstance behavioral addictions.

Method: A bibliometric and conceptual analysis was conducted on 1,591 peer-reviewed articles retrieved from Web of Science, Scopus, and PubMed (1992-2025). Publication trends, geographic distribution, and coauthorship patterns were quantified using Microsoft Excel and VOSviewer, while thematic clusters were identified through keyword co-occurrence with a minimum threshold of five co-occurrences. Data cleaning was performed using Python, automating the removal of duplicates and inconsistencies. Additionally, Python's matplotlib and seaborn libraries were used to visualize publication trends over time.

Results: The cognitive-behavioral paradigm emerged as dominant, with key concepts such as "impulsivity," "compulsive behavior," and "gambling" at the network's core. Neurobiological and sociocultural dimensions formed secondary clusters, whereas computational and transdiagnostic perspectives remained underrepresented. Country and author collaboration networks highlighted the United States and leading scholars (e.g., Potenza, Grant) as central hubs.

Conclusions: The findings reveal significant terminological fragmentation and thematic silos, underscoring the need for standardized vocabularies and interdisciplinary integration. This comprehensive overview provides actionable insights for researchers, clinicians, and policymakers to advance unified frameworks, foster inclusive collaborations, and guide future investigations in the field of behavioral addictions.

Objective: Latine college students at predominantly White institutions face discriminatory stress, increasing their risk for problematic alcohol use. The specific impact of daily discrimination and microaggressions on alcohol use and related consequences, relative to other college stressors (e.g., academics, finances), remains understudied. This study used an intensive daily longitudinal design to examine whether these experiences independently affect alcohol use and related consequences.

Method: The study enrolled 109 Latine student drinkers (M_age = 19.95; 77% female) from a large predominantly White institution in the northeastern United States. Participants completed a baseline survey, an in-person training session, and 28 consecutive daily surveys. Multilevel models analyzed the data, examining within- and between-person effects while controlling for college stress, trauma history, and relevant demographic variables.

Results: Participants had an average survey completion rate of 89.1% (∼25 of 28 surveys). Within-person, daily experiences of discrimination and microaggressions were associated with increased alcohol use and consequences. Between-person, these factors predicted alcohol-related consequences but did not significantly affect alcohol use when controlling for college stress, trauma, and demographics.

Conclusions: Daily discrimination and microaggressions independently contribute to alcohol use and its consequences for Latine students, beyond other common stressors faced by college students. These findings highlight the need for culturally sensitive interventions addressing discriminatory stress. Predominantly White institutions should also consider policy changes to better support minoritized students and mitigate the negative effects of discrimination on their well-being.

Objective: Motivational models of alcohol use emphasize that drinking motives (enhancement, coping, social, and conformity) drive alcohol consumption. However, few studies have directly tested how drinking motives relate to acute responses to alcohol, and existing studies typically omit social motives and expectancy effects and rely on solitary drinking paradigms with limited ecological validity. This preregistered study addresses these gaps by testing associations between drinking motives and alcohol's acute effects on emotions and social outcomes in a large, multiperson alcohol administration study with placebo control.

Method: Heavy-drinking young adults (N = 393; 50% female) completed the Drinking Motives Questionnaire-Revised and were grouped into 131 triads of unacquainted individuals. Groups consumed either alcohol (males: 0.82 g/kg; females: 0.74 g/kg) or placebo over 36 min. Interactions were video-recorded and coded for facial expressions (e.g., using Ekman's Facial Action Coding System), speech, and laughter. Postdrink, participants reported affect, stimulation, and social bonding.

Results: Multilevel structural equation modeling showed that many associations between drinking motives and acute alcohol responses, particularly enhanced stimulation and positive affect linked to enhancement, coping, and social motives, occurred similarly in both alcohol and placebo conditions, highlighting the significant role of expectancy effects. However, coping motives uniquely predicted greater perceived relief of negative affect specifically in the alcohol condition, even after accounting for other motives, despite no evidence of actual reductions in negative affect from pre- to postdrinking.

Conclusions: Findings underscore the value of considering expectancy effects and ecologically valid contexts when examining how motives shape alcohol responses. (PsycInfo Database Record (c) 2026 APA, all rights reserved).

Objective: Social network analysis offers a high-resolution framework for understanding social influences on alcohol use, but full-length assessments confer significant burden, giving rise to brief measures. However, few studies have empirically compared brief and full-length assessments. To address this, the present study examined the internal and external validity of both brief and full egocentric social network assessments and their ability to capture weak social ties. Method: In 405 adults (57.5% female) with alcohol use disorder, a full egocentric social network assessment estimated drinking behavior in the ego's 20 important alters, as well as their perceived closeness and frequency of interaction with their network, and the presence of supportive ties (mutual help organization members or treatment providers). The assessment yielded four social network drinking characteristics: percent drinking endorsement, percent heavy drinking endorsement, drinking frequency, and heavy drinking frequency. Measures from the full 20-alter assessment were compared to measures from the first 5 alters. Results: Associations between brief and full network measures were of large magnitude (rs = .53-.73, p < .0001). Internal psychometric properties of the social network drinking characteristics were robust and similar in both assessments and, in terms of external validity, 13/16 (81.3%) associations of network drinking with the ego's drinking severity were equivalent across both assessments. However, the brief assessment had less representation of mutual help organization members and treatment providers (ps < .01), resulting in a higher percent of alters endorsing drinking (p < .05). No other significant differences were present among other network drinking characteristics. Conclusions: These findings provide support for brief egocentric social network assessments, but also reveal limitations in characterizing potentially important weak social ties, namely the presence of mutual help organization members and treatment providers. Brief or full-length versions may be variably appropriate depending on the research and clinical aims. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Objective: Sexual assault perpetration is widespread among young men. According to the Confluence Model, hostile masculinity and impersonal sex are trait-level factors associated with sexual assault perpetration likelihood. Additionally, state-level factors, including alcohol intoxication, current emotions, and ability to modulate one's emotions, have been tied to sexual assault perpetration via the I3 Model. This study integrates these trait- and state-level factors into a single model to enhance its predictive power and better inform future interventions.

Method: Data were collected from 2019 to 2023. Young, single, nonproblem drinking men, who had been sexually active with a woman within the past month (N = 282; 34.8% people of color), completed background questionnaires and were randomly assigned to a positive or negative mood induction, and then to consume alcohol (target peak breath alcohol concentration = .08%) or a control beverage before projecting themselves into a hypothetical, sexual scenario. Then, men indicated their likelihood of engaging in nonconsensual sexual activity with their hypothetical partner (i.e., perpetration likelihood).

Results: A moderated-mediation structural equation model demonstrated that trait hostile masculinity and impersonal sex interacted with state alcohol intoxication and mood to predict state sexual arousal. State sexual arousal subsequently interacted with state impulsivity to predict state difficulties modulating emotions, which predicted perpetration likelihood during the hypothetical scenario.

Conclusions: Integrating trait- and state-level factors is of paramount importance to understanding sexual assault prevention. Interventions targeting emotional modulation during sexual situations may be especially useful among aroused or impulsive individuals, due to their mood, alcohol intoxication, and attitudes regarding hostile masculinity and impersonal sex.

Objective: Individual differences in smoking reinforcement and cue-specific cigarette craving are theorized to influence smoking cessation and relapse. However, there has been little laboratory research that prospectively evaluates these relationships. The present study evaluated whether lab-based indices of pretreatment smoking reinforcement and cue-specific craving predicted subsequent bio-verified abstinence.

Method: Participants were 253 adults (aged 28-70, 54% female, 78% White, 3% Hispanic) who reported smoking more than five cigarettes per day when enrolled in a randomized, double-blind, placebo-controlled smoking cessation trial (NCT03262662). During a lab visit ∼1 week before treatment began, participants completed the Choice Behavior under Cued Conditions task. On each of the 36 Choice Behavior under Cued Conditions trials, participants spent between $0.01 and $0.25 for a chance (5%-95%) to sample a cigarette or a cup of water. All participants received varenicline, either during Weeks 1-15 or 4-15 of the study, along with counseling at each visit, and attempted to quit smoking at the end of Week 4. Cotinine-bio-verified (< 15 ng/mL) 7-day point-prevalence abstinence was assessed at Weeks 6, 8, 15, and 28. The predictive validity of pretreatment smoking reinforcement and cue-specific craving on abstinence were examined in logistic regressions.

Results: As predicted, greater pretreatment smoking reinforcement predicted lower odds of abstinence, an effect that did not vary significantly across time, treatment groups, or biological sex. Pretreatment cue-specific craving was not predictive of abstinence.

Conclusions: This study highlights the theoretical importance of smoking reinforcement and the predictive utility of Choice Behavior under Cued Conditions in identifying those at risk for relapse. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Objective: Emotion measurement is central to capturing acute alcohol reinforcement and so to informing models of alcohol use disorder etiology. Yet our understanding of how alcohol impacts emotion as assessed across diverse response modalities remains incomplete. The present study leverages a social alcohol-administration paradigm to assess drinking-related emotions, aiming to elucidate impacts of intoxication on self-reported versus behaviorally expressed emotion.

Method: Participants (N = 60; M_age = 22.5; 50% male; 55% White) attended two counterbalanced laboratory sessions, on one of which they were administered an alcoholic beverage (target blood alcohol content .08%) and on the other a nonalcoholic control beverage. Participants in both conditions were accurately informed of beverage contents and consumed study beverages in assigned groups of three while their behavior was videotaped. Emotion was assessed via self-report as well as continuous coding of facial muscle movements.

Results: The relationship between self-reported and behaviorally expressed emotion diverged significantly across beverage conditions: positive affect: b = -0.174, t = -2.36, p = .022; negative affect, b = 0.4319, t = 2.37, p = .021. Specifically, self-reports and behavioral displays converged among sober but not intoxicated participants. Further, alcohol's effects on positive facial displays remained significant in models controlling for self-reported positive and negative emotion, with alcohol enhancing Duchenne smiles 20% beyond effects captured via self-reports, pointing to unique effects of alcohol on behavioral indicators of positive emotion.

Conclusions: Findings highlight effects of acute intoxication on the convergence and divergence of emotion measures, thus informing our understanding of measures for capturing emotions that are most proximal to drinking and thus most immediately reinforcing of alcohol consumption.

Objective: This article introduces the common and unique latent transition analysis (CULTA), a novel approach to studying alcohol intoxication dynamics in young adults engaged in heavy episodic drinking. CULTA merges the common and unique trait-state model with latent transition analysis to separate stable, traitlike intoxication components from transient fluctuations while modeling transitions between distinct drinking profiles.

Method: A sample of 222 young adults wore transdermal alcohol concentration sensors for 6 days, capturing real-time alcohol levels. The CULTA model decomposed intoxication variability into common and unique influences across four transdermal alcohol concentration features-peak, rise rate, fall rate, and duration. Latent intoxication profiles were identified, and transition probabilities between profiles were estimated with a focus on the influence of alcohol use disorder risk measured by the Alcohol Use Disorders Identification Test.

Results: Two latent intoxication profiles emerged. The first, chronic heavy episodic drinking, was characterized by persistently high intoxication without significant inertia, while the second, inertia-driven drinking, featured moderate episodic intoxication with a strong autoregressive effect, reflecting lingering intoxication that dissipates over time. Individuals with higher Alcohol Use Disorders Identification Test scores were more likely to remain in or transition to the chronic heavy episodic drinking profile. Although peak intoxication and rise rate showed limited individual variability, fall rate and duration varied substantially, marking them as potential targets for intervention.

Conclusions: CULTA advances our understanding of alcohol intoxication by distinguishing stable from transient influences and modeling transitions between drinking states. These findings suggest that interventions should address both persistent and situational aspects of intoxication-especially by reducing duration and fall rate-and encourage research across longer periods and populations.
