Objective: Compared with men, women are disproportionately affected by alcohol, including greater risks of behavioral impairment and relapse from abstinence-based treatments. One potential mechanism underlying this disparity is ovarian hormone fluctuations across menstrual cycle phases, particularly estradiol (E2). Preclinical and clinical studies have shown that E2 levels positively correlate with alcohol consumption, suggesting E2 modulates drinking. Rewarding properties of alcohol are thought to mediate this relationship. The present study tested the degree to which women report increased rewarding effects from alcohol and heightened attention to alcohol-related cues when E2 was elevated during the late follicular phase of the menstrual cycle.

Method: Fifty women aged 21-29 participated in a within-subjects placebo-controlled study examining how menstrual cycle phase alters the rewarding properties of alcohol and alcohol-associated cues when sober and intoxicated, as measured by their attentional bias toward alcohol-associated cues and subjective reports. Measures were obtained following 0.60 g/kg alcohol and placebo during the early follicular phase when E2 was low and the late follicular phase (i.e., ovulation) when E2 was elevated.

Results: Attentional bias to alcohol-associated cues was greater during the late follicular phase in both sober and intoxicated states. Women reported rewarding effects from alcohol, but no effects of phase were observed.

Conclusions: The findings suggest that the rewarding properties of alcohol-associated cues might be enhanced during the late follicular phase of the menstrual cycle when E2 is elevated, possibly increasing the risk for excessive drinking in women during this phase.

Objective: The Alcohol Addiction Research Domain Criteria (AARDoC) is an organizational framework for assessing heterogeneity in addictive disorders organized across the addiction cycle domains of incentive salience, negative emotionality, and executive functioning and may have benefits for precision medicine. Recent work found pretreatment self-report items mapped onto the addiction cycle domains and predicted 1- and 3-year alcohol use disorder treatment outcomes. Given the potential utility of the addiction cycle domains for predicting relevant treatment outcomes, this study sought to evaluate the longitudinal measurement invariance of the domains.

Method: We conducted a secondary analysis of individuals with alcohol use disorder (n = 1,383, 30.9% female, 76.8% non-Hispanic White, 11.2% Hispanic) who participated in the COMBINE study. Eleven items assessed at pre- and posttreatment were included in exploratory structural equation modeling (ESEM) and longitudinal invariance analyses.

Results: The pre- and posttreatment ESEM models had factor loadings consistent with the three addiction cycle domains and fit the data well. The ESEM factor structure was invariant from pre- to posttreatment (representing configural invariance) and metric invariance (factor loadings) was largely supported, but analyses failed to support scalar invariance (item-level thresholds) of the addiction cycle domains.

Conclusions: A three-factor structure representing addiction cycle domains can be modeled using brief self-report measures pre- and posttreatment. Individuals demonstrated a downward shift in the level of item endorsement, indicating improvement with treatment. Although this 11-item measure might be useful at baseline for informing treatment decisions, results indicate the need to exercise caution in comparing the addiction cycle domains pre- to posttreatment within persons.

Objective: Women in academia publish fewer papers and receive fewer citations than men. These gender gaps likely reflect systemic biases operating over several levels, from journal editorial policies to academic career progression. This study sought to characterize gender gaps for publications and citations in the field of gambling studies.

Method: An automated gender inference procedure classified authors' binarized gender from their first names. Gender gaps were computed for publications and citations of papers in gambling studies, using the wider field of addiction science as a benchmark. Publication data were scraped from eight peer-reviewed gambling/addictions journals and separately from all gambling publications listed in PubMed.

Results: Men authored 16% more publications than women among gambling papers and 23% more publications among nongambling addictions papers. Although robust gender gaps were observed in specialist gambling journals, we find limited overall evidence for gender inequality being greater in gambling studies. Indeed, among nongambling addiction papers, men published more, despite a greater apparent representation of women in the field. The gender gap was most pronounced for the last authorships, denoting seniority. Among the first authorships, there was variability between journals, and some journals displayed approximate parity. There was limited evidence for any corresponding gender gap in citation counts.

Conclusions: Gender gaps in gambling research, and addiction science more broadly, adhere to wider trends in academia, including the associations with academic seniority. Variability between individual journals supports the role of journal editorial policies to increase the representation and visibility of women researchers in addiction science.

Objective: There is a growing consensus that problematic pornography use (PPU), one of the most commonly reported compulsive sexual behaviors, is related to a number of internalizing psychiatric symptoms (e.g., anxiety, depression). However, little is known about the potential comorbidity of PPU and suicidal thoughts. Given known links between PPU and higher levels of guilt, shame, and moral disapproval, it may be that PPU may be related to suicidal thoughts.

Method: Using two independent samples, we cross-sectionally (Sample 1: undergraduates, n = 422) and longitudinally (Sample 2: nationally representative sample of U.S. adults, n = 1,455) tested for associations between PPU and past-month suicidal ideation and perceived likelihood of suicidal behaviors, while controlling for frequency of pornography use, moral disapproval, moral incongruence, and religiousness.

Results: Cross-sectionally, PPU was related to higher levels of self-perceived likelihood of suicidal behaviors, but not past-month suicidal thoughts. Longitudinally, PPU was related to higher initial levels (i.e., intercept) of past-month suicidal thoughts and self-perceived likelihood of suicidal behaviors, but not changes in either (i.e., slope). The frequency of pornography use was statistically unrelated to each outcome for both samples, while moral beliefs about pornography use showed mixed relationships.

Conclusions: Clinicians working with patients reporting PPU may consider ways it may contribute to suicidal thinking. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Social network analysis (SNA) characterizes the structure and composition of a person's social relationships. Network features have been associated with alcohol consumption in observational studies, primarily of university undergraduates. No studies have investigated whether indicators from a person's social network can accurately identify the presence of alcohol use disorder (AUD), offering an indirect strategy for identifying AUD.

Method: Two cross-sectional case-control designs examined the clinical utility of social network indicators for identifying individuals with AUD (cases) versus demographically matched drinkers without AUD (controls). Study 1 (N = 174) used high-resolution egocentric SNA assessment, whereas Study 2 (N = 189) used a brief assessment.

Results: In Study 1, significant differences between AUD+ participants and controls were present for network alcohol severity (i.e., heavy drinking days; d = 1.23) and frequency (d = 0.35), but not network structural features. Network alcohol severity exhibited very good classification of AUD+ individuals versus controls (area under the curve [AUC] = 0.80), whereas network frequency did not (AUC = 0.61). In Study 2, significant differences were present for network alcohol severity (d = 1.02), quantity (d = 0.74), and frequency (d = 0.43), and severity exhibited good differentiation (AUC = 0.76).

Conclusions: Social network indicators of alcohol involvement robustly differentiated AUD+ individuals from matched controls, and the brief assessment performed almost as well as the high-resolution assessment. These findings provide proof-of-concept for severity-related SNA indicators as promising novel clinical assessments for AUD. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Near-misses are a structural characteristic of gambling products that can be engineered within modern digital games. Over a series of preregistered experiments using an online slot machine simulation, we investigated the impact of near-miss outcomes on subjective ratings (motivation, valence) and two behavioral measures (speed of gambling, bet size).

Method: Participants were recruited using Prolific and gambled on an online three-reel slot machine simulator that delivered a one in three rate of X-X-O near-misses. Study 1 measured trial-by-trial subjective ratings of valence and motivation (Study 1a, n = 169; Study 1b, n = 148). Study 2 (n = 170) measured spin initiation latencies as a function of the previous trial outcome. Study 3 (n = 172) measured bet size as a function of the previous trial outcome.

Results: In Study 1a, near-misses increased the motivation to continue gambling relative to full-misses, supporting Hypothesis 1. On valence ratings, near-misses were rated significantly more positively than full-misses, in the opposite direction to Hypothesis 2; this effect was confirmed in a close replication (Study 1b). In Study 2, participants gambled faster following near-misses relative to full-misses, supporting Hypothesis 3. In Study 3, participants significantly increased their bet size following near-misses relative to full-misses, supporting Hypothesis 4.

Conclusion: Across all dependent variables, near-miss outcomes yielded statistically significant differences from objectively equivalent full-miss outcomes, corroborating the "near-miss effect" across both subjective and behavioral measures, and in the environment of online gambling. The unexpected findings on valence ratings are considered in terms of boundary conditions for the near-miss effect, and competing theoretical accounts based on frustration/regret, goal generalization, and skill acquisition.

Objective: To examine early school leaving in a longitudinal cohort of all high school students treated for substance use disorder (SUD) and their demographic counterparts in Norway.

Method: From the National Patient and National Population Registries, we extracted (a) all high school students born in 1991-1992 who received SUD treatment during 2009-2010 (N = 648; n_alcohol = 95, n_cannabis = 327, and n_{other drugs} = 226) and (b) their age-and-gender matched counterparts (n = 647). From the National Educational Database, we obtained enrollment and graduation status for these two cohorts throughout the designated school period of 5 years. We estimated the hazards of early school leaving as a function of students' treatment for alcohol, cannabis, and other drug use disorders and other known risk factors.

Results: Nine out of 10 adolescents receiving SUD treatment left high school early (89%) compared with one in four (27%) from the matched cohort; 422 (73.5%) of these left high school during or after the treatment year. Multivariate discrete-time models revealed significant and ordered associations between receiving SUD treatment and early school leaving, HR_alcohol = 3.09 [1.96, 4.89], HR_cannabis = 3.83 [2.64, 5.56], HR_{other drugs} = 5.16 [3.32, 8.03], even after accounting for individual-level (sex, immigrant background, criminal charges, and mental health treatment), family-level (family structure, parental education, and family income), and structural risk factors (municipal size, county employment, and dropout rates).

Conclusion: Adolescents receiving SUD treatment remain especially vulnerable for early school leaving. These findings underscore the importance of improving and coordinating health and educational services for youth in SUD treatment. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Objective: Negative reinforcement models suggest that negative affect should predict event-level substance use, however, supporting daily-life evidence is lacking. One reason may be an emphasis in ecological momentary assessment (EMA) research on use behavior, which is subject to contextual and societal constraints that other substance outcomes, such as craving, may not be subject to. Therefore, the present study tested momentary, within-person reciprocal relations among negative affect and craving for alcohol and cannabis in daily life.

Method: Adults (N = 48) completed 60 days of EMA, consisting of four daily reports spanning 7 a.m.-11 p.m. assessing current negative affect and alcohol/cannabis craving. Preregistered analyses used dynamic structural equation modeling to test whether (a) within-person increases in negative affect co-occurred with within-person increases in alcohol and cannabis craving, and (b) within-person increases in negative affect predicted later within-person increases in craving (and vice versa), and (c) relations differed by substance use frequency.

Results: Within-person increases in negative affect were contemporaneously associated with within-person increases in alcohol and cannabis craving. However, increases in negative affect did not prospectively predict increases in craving, and within-person increases in craving did not prospectively predict within-person increases in negative affect. Within-person relations were not moderated by substance use frequency.

Conclusions: Negative affect and craving were associated in community adults. However, results advance a growing body of EMA work suggesting that the association of daily-life negative affect and substance use is, at best, not straightforward. Careful attention is needed to better translate existing negative reinforcement theory to the realities of daily life. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Researchers have documented robust associations between food and alcohol disturbance (FAD-intoxication; restricting caloric intake before or during alcohol consumption to experience a quicker and/or more intense alcohol intoxication) and alcohol use and related negative consequences. However, most of this research has utilized cross-sectional designs. Consequently, two crucial gaps have not yet been filled: (a) the separation of the relatively stable, between-person and the fluctuating, within-person components in the relations between FAD-intoxication and alcohol-related constructs; and (b) the examination of the directionality of these within-person relations.

Method: Participants were college students (n = 686) who reported past-month binge drinking. Most participants identified as White (71.3%), female (78.4%), non-Hispanic (87.8%), with a mean age of 20.64 (SD = 3.25). Participants completed three online surveys assessing FAD-intoxication (College Eating and Drinking Behaviors Scale), alcohol use (Daily Drinking Questionnaire), and related negative consequences (Brief Young Adult Alcohol Consequences Questionnaire).

Results: Analyses revealed that FAD-intoxication was positively associated with alcohol use and related negative consequences at the between-person level. Additionally, at the within-person level, FAD-intoxication at Time 2 significantly predicted alcohol use at Time 3. Notably, the cross-lagged effect from FAD-intoxication at Time 1 to alcohol use at Time 2 was not significant. FAD-intoxication did not significantly predict negative consequences. Neither use nor consequences significantly predicted FAD-intoxication.

Conclusions: Our results suggest that FAD-intoxication is relevant to the study of alcohol use and related negative consequences and should be considered in interventions targeting alcohol use and related negative consequences among students who endorse binge drinking.

Objective: This study assessed the ecological validity of the Yale Food Addiction Scale (YFAS 2.0) with ecological momentary assessment (EMA) and explored the internal consistency and convergent validity of a momentary food addiction scale.

Method: Adults (N = 49) who met criteria for binge-eating disorder and/or food addiction (age = 34.9 ± 12.1 years; 77.1% cisgender female; 55.1% non-Hispanic White) completed online questionnaires and a 10-day EMA protocol. Analyses examined (a) associations between the YFAS 2.0 and EMA-measured variables corresponding to food addiction criteria, (b) reliability of a momentary food addiction scale (EMA-FA), and (c) concurrent associations between EMA-FA and EMA-measured negative affect, impulsivity, eating expectancies, body satisfaction, consumption of palatable food, and taste response to palatable food.

Results: YFAS scores were associated with EMA-reported variables corresponding to food addiction criteria (ps < .045). The multilevel reliability for EMA-FA was adequate (ω = .75-.94). Individuals with higher EMA-FA scores reported greater negative affect, impulsivity, appetite, palatable food consumption, taste response to palatable food, and contrary to expectations, greater body satisfaction (ps < .01). Within-person effects emerged for EMA-FA predicting higher negative affect, impulsivity, likelihood of palatable food consumption, more pleasurable taste responses after consuming palatable foods, yet lower body satisfaction, appetite, and eating expectancies (ps < .01).

Conclusions: Results support the ecological validity of the YFAS 2.0, and additional evidence of convergent validity and internal consistency was demonstrated for a momentary food addiction scale. This assessment of the psychometric properties of the YFAS will ultimately further its utility and relevance in the study and diagnosis of food addiction.
