OBJECTIVE: This study assessed differences in the prevalence and correlates of different cannabis modes of administration (MOAs) between those reporting co-use (past 30-day nicotine/tobacco and cannabis use and or cannabis-only use. METHOD: Participants were adults reporting past 30-day cannabis use (n=3,488) who provided data for a repeated cross-sectional online survey (September 2020-September 2024). Prevalence and relative rankings of past 30-day use of nine different cannabis MOAs (smoking, vaping, dabbing, eating, drinking, oil, lotion, dissolvable, blunt use) were examined across past those reporting 30-day cannabis-only use and co-use. ANCOVA tests examined associations of co-use (vs cannabis-only use) and past 30-day combustible MOA use (combustible-only, non-combustible-only, both) with respiratory problems and past 30-day frequency of medical and recreational cannabis use. RESULTS: Smoking cannabis was the most common MOA among cannabis-only (72%) and co-users (83.1%). Among those reporting co-users, blunt use was the second most popular MOA (64.8%), then vaping (44%), and then edibles (36.5%). In the cannabis-only group, edibles were the second most common MOA (47.8%), then blunt use (36.1%), and vaping (33.4%). Combustible MOA use and co-use (vs cannabis-only use) were associated with more severe respiratory problems and more frequent medical and recreational cannabis in the past 30-days. Conclusions Those who co-use nicotine/tobacco with cannabis and those consuming combustible MOAs may be at increased risk of health consequences and more frequent cannabis use.

INTRODUCTION: Cannabis Use Disorder (CUD) can come with intense cravings, which can trigger compulsive use/relapse, underscored by anterior cingulate cortex (ACC) hyperactivity during cannabis cue-reactivity functional neuroimaging (fMRI) tasks. ACC activity can be reduced during real-time fMRI-based neurofeedback (fMRI-neurofeedback) in participants who use substances other than cannabis, but remains untested in CUD. We investigated the feasibility of fMRI-neurofeedback to reduce ACC activity and subjective craving in 10 participants with moderate-to-severe CUD. METHODS AND MATERIALS: A cue-reactivity fMRI task identified participants' voxels-of-interest (VOI) within the ACC (ACC). During two identical runs of 7 Tesla fMRI-neurofeedback, participants were instructed to use self-selected strategies to reduce ACC activity while receiving real-time feedback via a digital craving bar (ACC activity) when viewing cannabis images (down-regulation), and to simply look at neutral images (non-regulation). We examined the change in real-time percentage signal change (PSC) of the ACC during down-regulation versus non-regulation, and post-hoc (offline) whole-brain activation changes. RESULTS: Analysis of real-time data revealed that down-regulation versus non-regulation was associated with reductions in ACC PSC (p < 0.05). Further, whole-brain analysis reported down-regulation versus non-regulation was associated with lower activity in the ACC, posterior insula, and hippocampus; and greater activity in the anterior insula and middle frontal gyrus (p < 0.05, FWE-corrected). Subjective craving did not change pre-to-post fMRI-neurofeedback and did not correlate with ACC PSC or whole-brain brain activity (p > 0.05). CONCLUSION: fMRI-neurofeedback may reduce the activity of regions associated with craving in CUD. This effect appeared to be dissociable from subjective craving. These observations need to be confirmed in larger samples with placebo-controlled conditions.

This systematic review synthesizes empirical evidence on the associations between loot box engagement and adolescents' behavioral or psychological outcomes. Following the PRISMA guidelines, 26 empirical studies published between 2017 and 2025 were identified through comprehensive searches in PsycINFO, ERIC, Medline, Web of Science, Scopus, Ovid, PubMed, and ScienceDirect. Guided by the Stimulus-Organism-Response (S-O-R) model, the review categorizes findings into three domains: (1) external stimuli associated with exposure to loot boxes, (2) cognitive and habitual factors that mediate individual responses, and (3) behavioral outcomes related to problematic engagement. External stimuli interact with cognitive biases and habitual tendencies to shape adolescents' engagement patterns. Four hypothetical pathways are proposed: (1) The Gaming-Loot Box-Gambling Convergence Pathway; (2) The Multifactorial Pathway Influencing Loot Box Engagement; (3) The Moderating Pathway of Perceived Normative Pressure; and (4) The Feedback Loop Between Problematic Use and Cognitive-Behavioral Factors. The findings offer implications for prevention and youth protection in digital gaming contexts.

Cannabis retail surveillance is crucial to inform regulations and enforcement efforts. This point-of-sale audit study examined marketing practices and compliance with age verification rules, required signage, and marketing restrictions among 161 cannabis retailers in 5 US cities in states authorizing nonmedical cannabis retail (Los Angeles [LA], California; Las Vegas [LV], Nevada; Denver, Colorado; Portland, Oregon; Seattle, Washington) in summer 2025. Descriptive and bivariate analyses characterized retailers overall and across cities. Overall, 84.5 % of retailers requested age verification upon entry (range: Seattle = 43.3 % to LV = 100 %); 8.1 % never verified (range: LV/Denver = 0 % to Seattle = 26.7 %). All 5 states required pregnancy-related warning postings/brochures, observed in 64.6 % (less often in LA = 30.8 % and LV = 46.9 %). Nevada and Oregon required signage prohibiting on-site consumption, observed in 51.6 % overall (LV = 81.3 %, Portland = 86.7 %). California and Washington required signage indicating negative impacts on children/youth, posted in 42.2 % (LA = 20.5 %; Seattle = 80.0 %). All 5 states restricted youth-oriented packaging, found in 24.2 % (more often in Denver = 53.3 % and LV = 40.6 %). Other targeted populations (based on advertisements/promotions) included veterans/military (12.4 %), senior citizens (9.3 %), LGBTQ+ (8.7 %), and racial/ethnic minorities (7.5 %). Colorado, Oregon, and Washington prohibited health claims in advertising, found in 65.8 % (Denver = 40.0 %, Portland = 40.0 %, Seattle = 70.0 %). California, Colorado, and Washington restricted outdoor business signage, identified at 36.6 % overall (LA = 18.2 %, Denver = 7.7 %, Seattle = 40.0 %). California, Oregon, and Washington restricted discounting, identified in 93.8 % (LA = 92.3 %, Portland = 96.7 %, Seattle = 86.7 %). Further, 39.8 % promoted online ordering, 33.5 % curbside delivery, pick-up, or drive-through options, and 13.7 % home delivery. Given compliance-related issues with many regulations (e.g., required signage, prohibitions on youth-oriented marketing, health claims), states' cannabis retail regulations and enforcement must be strengthened.

PURPOSE: Research on ethnic differences in alcohol use has relied on broad groupings, potentially obscuring patterns across specific ethnic groups. Single data sources often include few participants from minoritised ethnic groups, a meta-analytic approach across data sources can overcome this limitation. This study examined, by ethnicity, the prevalence of i) alcohol use and binge-drinking, and associations of ii) alcohol use and binge-drinking with psychological distress. METHODS: A secondary analysis of eight representative surveys in England (N=112,791) was conducted. Alcohol was assessed using validated measures and categorised as i) non- (AUDIT-C score of 0), ii) low-risk (AUDIT-C score of 1-5), iii) increased-risk (AUDIT-C score of 6 or more), and iv)binge-drinker. Binge-drinking analyses were restricted to drinkers only. Psychological distress was measured using validated scales. Ethnicity was categorised using the most specific available classifications. Regression models estimated prevalence and associations within each survey, followed by a meta-analytic pooling of results from four surveys. RESULTS: Minority ethnic groups were more likely to be non-drinkers and less likely to be increased-risk or binge-drinkers compared with White British groups. The pooled association between psychological distress and non-drinking was significant for the White British group(OR=1.46,95%CI=1.34-1.59). The association between psychological distress and increased-risk drinking was significant for the Indian group (OR=1.43,95%CI=1.05-1.96). The association between psychological distress and binge-drinking was significant for White British groups (OR=1.14, 95%CI=1.08-1.20), compared to those of the same ethnicity without distress. CONCLUSION: Collapsing ethnicities into broad categories masks differences in patterns of alcohol use, for example, the difference between specific South Asian ethnic groups. Positive associations between alcohol use and psychological distress were identified for some minority ethnic groups, suggesting that alcohol may be used as a coping mechanism.

OBJECTIVES: Growing evidence suggests that family factors play an important role in adolescent problematic smartphone use. However, few studies have examined how specific dimensions of perceived co-parenting are related to distinct symptoms of problematic smartphone use. Network analysis offers a useful approach for investigating these associations in detail. This study aimed to model a cross-lagged network of co-parenting factors and problematic smartphone use using longitudinal data to identify their temporal relationships among rural adolescents. METHODS: A total of 494 adolescents (51.8% boys, M = 15.56, SD = 0.60) from rural areas of China were assessed at three time points, each separated by a 3-month interval. Two cross-lagged panel networks were examined to model the temporal associations among factors of perceived co-parenting and problematic smartphone use. RESULTS: Withdrawal consistently emerged as the most central and influential symptom within the problematic smartphone use network. In the bridge network linking co-parenting and problematic smartphone use, mother conflict and social comfort functioned as key bridge nodes. In addition, father disparagement was identified as a co-parenting dimension that exerted a substantial predictive influence on symptoms of problematic smartphone use. CONCLUSIONS: The findings highlight the dynamic interplay between perceived co-parenting and adolescent problematic smartphone use, underscoring the importance of family system processes. Although traditional Confucian culture positions mothers as the primary caregivers, our findings suggest that strengthening fathers' support for mothers' parenting, while reducing parental conflict and disparagement, may help prevent and mitigate problematic smartphone use among adolescents.

Given the prominent role of metacognitions highlighted by the Self-Regulatory Executive Function model, longitudinal evidence is warranted to clarify how metacognitions about gambling and emotion regulation may jointly contribute to gambling disorder (GD). The present study aimed to test a cross-lagged panel model (CLPM), which allows testing not only the relative prospective values of metacognitions about gambling and emotion regulation on GD tendency, but also the bidirectional associations, if any, among them. Five hundred eighty-five Chinese adult lifetime gamblers (M = 30.09, SD = 8.13; 48.2% female) participated in this two-wave longitudinal online questionnaire study. CLPM results indicated that both positive and negative metacognitions about gambling were more salient predictors than emotion regulation of GD tendency. In addition, negative metacognitions about gambling were significantly predicted by GD tendency and emotion regulation, indicating a metacognition-GD vicious cycle as well as a potential protective role of emotion regulation in the cycle. These findings highlight the important role of metacognitions in GD vulnerability and provide clinical insights such as incorporating emotion regulation training in Metacognitive Therapy based interventions for GD.

BACKGROUND: Rapid cannabis legalization in the United States has heightened concern about prenatal exposure as social acceptance increases. While tobacco use during pregnancy has steadily declined, emerging evidence suggests cannabis use may be rising. We examined national trends in tobacco-only use, cannabis-only use, and co-use among pregnant individuals from 2015 to 2023 and identified associated sociodemographic factors. METHODS: We analyzed nationally representative 2015-2023 National Survey on Drug Use and Health data restricted to pregnant women ages 15-44 (N = 6,099). Outcomes were self-reported past-30-day tobacco-only use, cannabis-only use, and co-use. Weighted prevalence was estimated for 2015-2019, 2020, and 2021-2023. Multivariable logistic regressions for 2015-2019 and 2021-2023 assessed predictors relative to non-use, reporting adjusted odds ratios and average marginal effects. Regressions were not estimated for 2020 due to limited sample size. RESULTS: Tobacco-only use declined from 12.0% in 2015 to 3.9% in 2023. Cannabis-only use more than doubled pre-pandemic and peaked at 6.3% in 2022, surpassing tobacco before converging in 2023. Co-use declined to 0.8% by 2023. Pre-pandemic, lower education, unmarried status, lower income, and public insurance were associated with higher tobacco-only use and co-use. Hispanic individuals had lower likelihoods of all use patterns relative to non-Hispanic White individuals. Post-pandemic, educational gradients in cannabis-only use emerged, while Medicaid and Medicare coverage remained associated with higher tobacco-only use and uninsured status became associated with higher cannabis-only use. CONCLUSION: Prenatal substance use patterns are shifting, with cannabis surpassing tobacco in recent years. Updated screening, counseling, and policy responses are needed to address evolving prenatal exposure risks.

Cigarette relighting is common yet understudied, despite its potential implications for tobacco treatment, and previous associations with elevated risk for lung diseases and cancer. An online survey was conducted to determine cigarette relighting prevalence and correlates among a national probability sample of adults who smoke cigarettes (n = 1,697). Overall, 67% (n = 1,161) of participants reported relighting in the last 30 days. Compared to other adults who smoke, individuals who relit frequently (at least several times per week, 45.9%, n = 779) in the last 30 days were more likely to be Black (17.4% vs. 10.4%), have ≤ a high school diploma (65.1% vs. 49%), <$50 K annual income (62.5% vs. 41.7%), be uninsured (15.5% vs. 10.2%), and use long rod cigarettes (58.6% vs. 39%). Individuals who relit frequently (vs. infrequently) in the last 30 days reported relighting to save money (69.6% vs. 43.6%, p < 0.001), cut down or quit (40.6% vs. 17.1%, p < 0.001), or reduce harm (33.9% vs. 10.3%) and were more likely to believe relighting had decreased their smoking (39.6% vs. 10%). Very few participants' providers had discussed relighting with them. Overall, this comprehensive national study focused on cigarette relighting documents that this behavior is prevalent among adults who smoke, associated with specific sociodemographic characteristics and believed by some participants to help reduce harm. We recommend relighting be assessed in tobacco treatment and providers educated about relighting and its sociodemographic and other correlates. Research is needed on potential treatment implications so providers can consider relighting appropriately in their pharmacologic and behavioral treatment plans.

Military veterans in the United States often face significant obstacles or vulnerabilities known to maintain cigarette smoking including trauma exposure, Post-traumatic Stress Disorder (PTSD), chronic pain, nicotine dependence, withdrawal symptoms, and psychological distress. Behavioral economic principles, including delay discounting and demand, provide a novel framework for understanding the relation between these vulnerabilities and the reinforcement value of cigarettes, a novel potential therapeutic target. This study examined the cumulative effect of multiple vulnerabilities on the reinforcement value of cigarettes among the veterans enrolled in a remotely delivered smoking cessation treatment study. Participants (n = 104) were primarily middle-aged men (52 years old (SD = 10), 89% male). About half (52%) reported high levels of nicotine dependence; nearly all reported exposure to trauma (92%); 29% met criteria for possible PTSD; 52% reported elevated pain levels; and 21% reported severe psychological distress. The number of vulnerabilities was linearly associated with higher delay discounting rates in a cigarette-money cross commodity task, F(1,101) = 4.78, p = 0.031; greater demand intensity, F(1,102) = 14.11, p < 0.001; and lower demand elasticity, F(1,102) = 8.2, p = 0.005, in a cumulative manner, but unrelated to monetary discounting. These findings suggest that the selected vulnerabilities demonstrate a cumulative impact on the reinforcement value of cigarettes. This relation might help to explain the difficulties veterans encounter achieving long-term abstinence from smoking and underscore the need for novel treatment approaches that target the reinforcement value of cigarettes in the context of multiple vulnerabilities.

The study aimed to investigate the dynamic associations among meaning in life (MIL), metacognitions about mobile phone use, and adolescents' problematic mobile phone use (PMPU). A longitudinal design with a 6-month interval was adopted, involving a total of 831 adolescents who completed questionnaires assessing MIL, metacognitions about mobile phone use, and PMPU. The results indicated a significant bidirectional relationship between MIL and the severity of adolescents' PMPU. In addition, both positive and negative metacognitions about mobile phone use were positively and reciprocally associated with PMPU. Furthermore, MIL negatively influenced both forms of metacognitions over time. This study highlights the potential roles of metacognitions and MIL in the prevention and intervention of PMPU among adolescents, suggesting that both fostering MIL and modifying dysfunctional metacognitions may be effective targets.

The comorbidity between depression and alcohol use problems is well-documented, yet little research has examined how depression-related stigma may contribute to this comorbidity. Utilizing a daily diary design, the current study examined the concurrent (i.e., same-day) and lagged (i.e., next day) associations between felt depression stigma (i.e., shame and fear of being discriminated against or socially rejected due to one's depression) and alcohol use behaviors among a community sample of adults diagnosed with major depressive disorder (MDD). Participants (N = 92) reported experiences of felt depression stigma, number of alcoholic drinks consumed, and general psychological distress once a day over a period of 14 days, as well as their recent alcohol use and depressive symptoms at baseline. Multilevel modeling revealed that within-person fluctuations in felt depression stigma were positively associated with increased alcohol consumption and greater odds of engaging in heavy drinking on the same day, while controlling for relevant baseline and daily covariates. However, within-person fluctuations of felt depression stigma were not associated with the likelihood of same-day alcohol use or any of the next-day alcohol use outcomes. These findings highlight the role of stigma as a potential risk factor for harmful patterns of alcohol use among individuals with MDD, thus advancing our understanding of the etiology of depression-alcohol use comorbidity. Results also underscore the utility of addressing felt depression stigma and fostering adaptive coping in alcohol use prevention and treatment interventions tailored for individuals with MDD.

BACKGROUND: Remission from substance use disorders (SUD) is typically associated with improved quality of life and daily functioning. However, it is unclear whether people in long-term remission continue to experience heightened rates of daily functional impairment compared to people without prior SUD. OBJECTIVES: 1) To test whether functional impairment, measured with the World Health Organization Disability Assessment Schedule (WHODAS), is higher for people in long-term SUD remission than people with no lifetime SUD, and 2) to estimate degree of impairment attributable to remitted SUD per se vs. other causes. SAMPLE: Probability sample of U.S. adults in sustained SUD remission (n = 9,295) or with no lifetime SUD (n = 92,228) drawn from the National Survey of Drug Use and Health (NSDUH). ANALYSES: Total impairment was compared between groups with t-tests of unadjusted WHODAS. Degree of impairment related to long-term remission itself vs. current severe psychological distress, social determinants of health, and recent substance use was evaluated with hierarchical generalized linear models and follow-up sensitivity analyses. RESULTS: People in the remitted sample had higher average WHODAS impairment scores than those who had never experienced SUD (5.14 vs. 3.32) and were less likely to report experiencing no impairment (33.3% v 52.0%). Prior-year psychological distress and mental health treatment accounted for 40% of variance in functional impairment, compared to 2% variance explained by remission itself. Greater impairment among remitted people was also strongly associated with younger age and female sex. CONCLUSIONS: People in long-term remission are more likely to experience difficulty with daily functioning than people with no lifetime SUD. Impairment is more strongly related to acute psychological distress than residual effects of SUD per se for people with at least one year of recovery. Future work should examine approaches to reducing psychological distress in this large but frequently overlooked population, which may include mental health treatment, informal social support, or interventions to increase recovery capital.

With the rapid development of information technology, problematic internet use (PIU) has emerged as a significant concern. Although PIU manifests through a wide range of symptoms, limited research has explored how these symptoms interact, particularly when considering the between-person heterogeneity of PIU. Therefore, the present study aimed to identify distinct PIU subtypes and to compare their symptom networks. A total of 2,376 college students (M = 19.52 ± 1.02; 26.3% male) completed the Internet Addiction Test. Latent profile analysis identified three subtypes: Low, Moderate, and High PIU. Network analysis revealed both shared and subtype-specific features. Across subtypes, several symptom associations were consistently strong, and PIU6 (work suffers from internet use) emerged as a central symptom. The Low and Moderate PIU subtypes showed largely similar network structures, with PIU17 (failure to cut down online time) as another prominent symptom. However, the Moderate subtype additionally exhibited several negative associations between symptoms and lower centrality of PIU12 (fear of life without the Internet). PIU1 (staying online longer than intended) was prominent in both the Moderate and High PIU subtypes, but played a stronger role in the High PIU subtype. The High subtype was further characterized by a denser network with exclusively positive connections and higher centrality of PIU12. These findings highlight both common and subtype-specific symptom organization in PIU and suggest potential intervention targets across severity levels.

The use of electronic cigarettes has increased in recent years. However, the prevalence of this consumption among the female population is unknown. The objective of this review is to determine the prevalence of electronic cigarette use among women, taking into account continent, country, age, and course. A literature search was conducted in the PsycINFO, Pubmed, Web of Science (WOS) and SCOPUS databases to identify articles published between January 2015 and January 2025 that analysed the prevalence of electronic cigarette use among women. Forty-five studies were included and classified according to continent of origin: Europe (n = 10), America (n = 21), Asia (n = 7) and Oceania (n = 3). Four studies evaluated several countries simultaneously. In general, it was found that the prevalence of consumption in recent years is on the rise. The continent with the highest rate was America (28.8%), although countries on other continents, such as France (19.3%) and Kuwait (14.4%), also had high prevalence rates. The stage of life with the highest prevalence was young adulthood, with 6.2% having used them in the last 30 days. Furthermore, globally, it was found that the use of electronic cigarettes among women is lower than among men. Knowing the use of these devices among women allows for the development of specific preventive or treatment actions to reduce consumption in those territories and stages of life where the use of these devices is highest.

BACKGROUND: PTSD often co-occurs with and may exacerbate substance use disorders (SUD), but PTSD treatment is rarely available in residential/inpatient SUD care. We conducted a pilot feasibility randomized controlled trial of treatment as usual plus Written Exposure Therapy (TAU+WET) vs. TAU in residential SUD care. METHODS: N = 42 participants were randomly assigned to TAU + WET or TAU (60% men, 42% women; 39% Black, 37% white, 24% multiracial or another race; mean age = 37.43 years ± 10.79). PTSD symptoms were measured via the Posttraumatic Stress Disorder Checklist for DSM 5. Secondary outcomes were WET feasibility (completion rates) and acceptability (patient attitudes). Exploratory outcomes were depressive symptoms, trauma coping self-efficacy, emotion regulation difficulties, and substance use recovery capital. RESULTS: PTSD symptoms in both groups significantly improved from pre- to post-WET, with larger reductions among TAU + WET vs. TAU participants (F[1,40] = 55.33, p < 0.001, n = 0.58; M = -24.67, SE = 3.63, p < 0.001, 95% CI [-32.00, -17.35] vs. M = -15.43, SE = 3.99, p < 0.001, 95% CI [-23.50, -7.37]. TAU + WET participants were more likely than TAU participants to achieve PTSD remission (52% vs. 21%; χ [1] = 4.42, p = 0.044, OR = 0.244, 95% CI [.062, 0.965]) and showed significantly greater improvement than TAU participants across all exploratory outcomes. CONCLUSIONS: WET is effective, well tolerated, and may enhance TAU in residential substance use treatment. A larger RCT with a longer follow-up period is needed to assess post-residential SUD outcomes and whether improvements are maintained.

UNLABELLED: Cannabis use remains high, with nearly one-third of people who use cannabis meeting criteria for a cannabis use disorder (CUD). Despite the availability of evidence-based psychosocial interventions for CUD, the vast majority of individuals with CUD do not seek treatment, and attrition rates are high among those who do. Similarly, relapse rates are very high among individuals who make self-quit attempts. It is therefore critical to identify barriers to cannabis reduction and cessation to inform treatment and prevention efforts. Although the Perceived Barriers for Cannabis Reduction and Cessation Scale (PBCRCS) was developed to assess barriers for cannabis reduction and cessation, little research has examined the psychometric properties of the measure. OBJECTIVE: The current study examined the factor structure, measurement invariance of the measure across sex, and construct validity of the PBCRCS. METHOD: Participants were 527 (44.8% female) Hispanic/Latine adults (M = 36.54, SD = 10.29) who endorsed cannabis use. A confirmatory factor analysis supported the unidimensional model for PBCRCS with strong model fit. RESULTS: The PBCRCS demonstrated unidimensional factor structure and measurement invariance across sex. It was also positively related to cannabis-related processes and negative affect. CONCLUSIONS: The findings provide novel empirical support for the PBCRCS as a reliable measure of perceived barriers for cannabis reduction and cessation that is related to several affective and cannabis processes relevant to cannabis use and cessation. This measure can be used to identify and address barriers to cannabis reduction and cessation efforts. PUBLIC HEALTH SIGNIFICANCE: Cannabis use and cannabis use disorder are common, yet many people who want to cut down or quit face significant barriers that hinder their success. This study provides psychometric evidence that the PBCRCS is a reliable tool for identifying these obstacles, helping clinicians and public health practitioners better tailor interventions designed to help people reduce or stop cannabis use.

BACKGROUND: Sleep disturbance is a common and clinically significant symptom in individuals with alcohol use disorder (AUD), often persisting during abstinence and increasing the risk of relapse. However, the neurophysiological mechanisms underlying sleep dysfunction in AUD remain poorly understood. Long-range temporal correlations (LRTC) in neural oscillations reflect the temporal organization and excitation-inhibition (E/I) balance of brain networks. While altered LRTC has been observed in various psychiatric and sleep disorders, its role in AUD-and its potential relationship to sleep dysfunction during abstinence-has not been systematically investigated. This study aims to investigate whether altered LRTC in resting-state EEG is associated with sleep quality during abstinence in individuals with AUD. METHODS: This study included 39 AUD patients and 34 healthy controls. Subjective sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). Resting-state EEG data were obtained, and LRTC were calculated using detrended fluctuation analysis (DFA) across distinct frequency bands. RESULTS: Compared to healthy controls, AUD patients exhibited significantly reduced LRTC in the β and γ frequency bands. Within AUD group, poorer sleep quality was significantly associated with lower β band LRTC in the middle frontal lobe (r = 0.45, p = 0.037), right parietal lobe (r = 0.37, p = 0.039), middle parietal lobe (r = 0.42, p = 0.037), and occipital lobe (r = 0.386 - 0.392, ps. = 0.037). Moreover, β and γ band LRTC effectively distinguished AUD patients from healthy controls, with area under the curve (AUC) value of 0.80 (p < 0.001) and 0.77 (p < 0.001), respectively. CONCLUSION: Resting-state LRTC in high-frequency EEG bands are altered in AUD and related to sleep quality, suggesting their potential as an objective biomarker for assessing sleep disturbances in AUD.
