This study investigates the relationship between ADHD symptom severity, metacognition, problematic social media use, and cyberbullying/cybervictimization in treatment-naïve adolescents. Understanding these relationships is vital for enhancing ADHD intervention strategies. Using a cross-sectional design, 97 adolescents meeting DSM-5 criteria for ADHD without any comorbidity and 97 healthy controls were assessed. Measures included the Metacognitions Questionnaire for Children, Social Media Disorder Scale, Revised Cyberbullying Inventory-II, and Revised Conners' Parent Rating Scale-Short. The comparisons were performed with independent samples' t tests and the associations were estimated by using Pearson's bivariate correlations and multiple regression analyses. Results revealed that adolescents with ADHD exhibited higher levels of dysfunctional metacognitions, problematic social media use, cyberbullying, and cybervictimization compared to controls. Regression analysis showed significant positive associations between ADHD symptoms, specific metacognitions (e.g., positive meta-worry, cognitive monitoring), and problematic social media use. This study, the first of its kind among treatment-naïve ADHD adolescents, provides valuable insights into the relationship between ADHD symptoms and particular metacognitions (i.e. positive meta-worry, cognitive monitoring) and problematic social media use. These findings contribute to a deeper understanding of ADHD in adolescence and may inform the development of targeted prevention and treatment strategies, particularly relevant given adolescents' susceptibility to social media's influence and their potential for cognitive flexibility in rehabilitation contexts.

Despite adverse effects of tobacco and marijuana use on the adolescent brain, its use among youth remains high. Previous research shows associations between bullying and risks of substance use; less is known about racial teasing. This study examines associations of racial teasing, marijuana and/or electronic vapor products (EVP) use among adolescents, using 2021 Virginia Youth Risk Behavior Surveillance System (VYRBSS).

Irritable bowel syndrome (IBS) is a prevalent disorder of gut-brain function associated with psychological distress as well as work and quality of life impairment. Smoking has been linked to gastrointestinal dysfunction, however, research focused on the prevalence of IBS and smoking is limited. Previous research has shown that anxiety sensitivity is linked to increased risk of aversive bodily experiences and subsequent coping-oriented regulation efforts. Higher anxiety sensitivity has also been associated with processes linked to tobacco cigarette smoking lapse and relapse. There is a need to clarify the explanatory roles of anxiety sensitivity in the context of more severe IBS symptoms among persons with IBS who are current smokers.

The current study used U.S. young adult data to examine overall and age group-specific historical trends in (a) mean perceived risk and disapproval of cannabis use, and (b) risk/use and disapproval/use associations.

Among high school students, seniors report the highest levels of hazardous drinking behavior, including playing drinking games. Technology-based interventions are a promising approach for reducing hazardous drinking behavior among this age group.

The co-use of alcohol and cannabis is rising in prevalence, yet the mechanisms driving individuals to co-use are not well understood. Subjective response to alcohol or cannabis may predict the desire to use either substance. However, which specific facets of subjective response predict cross-substance craving remains unclear. The present study investigated whether acute administration of alcohol or cannabis facilitates cue-induced craving for the other substance, with an emphasis on the underlying subjective response mechanisms contributing to co-use. This is a secondary analysis of a behavioral pharmacology study that combined alcohol/cannabis administration with a cross-substance cue-reactivity paradigm in individuals who were heavy alcohol and heavy cannabis co-users. Over two sessions, twenty-nine individuals (17M/12F) self-administered alcohol or cannabis (in a crossover design), and then completed a cue-reactivity exercise with the other substance. Analyses tested how changes in subjective response variables following substance administration predicted cross-substance cue-induced craving. Following alcohol administration, greater subjective ratings of positive mood predicted significantly greater cue-induced cannabis craving (β = 1.14, SE = 0.41, t = 2.80, p = 0.010). Following cannabis administration, lower subjective effects ratings of positive mood/arousal predicted significantly greater cue-induced alcohol craving (β = -1.08, SE = 0.38, t = -2.85, p = 0.009; β = -2.38, SE = 1.13, t = -2.10, p = 0.047). This study identified subject response mechanisms contributing to cross-substance cue induced craving. These mechanisms include increases in positive mood following alcohol use and decreases in positive mood and arousal, akin to increases in relaxation, following cannabis use.

Flavored tobacco products increase appeal and lower barriers to nicotine addiction for young people. We compared environmental, psychosocial, behavioral, and demographic characteristics between youth who started with flavored and non-flavored (i.e., tobacco-flavored) combustible tobacco products (CTPs).

Cannabis is increasingly the first substance used by young people and research indicates that cannabis use may precede the onset of tobacco use. Little is known, however, about the role of cannabis use in stages of electronic nicotine delivery systems (ENDS) uptake and progression across young adulthood. This study examined the associations between past 30-day (P30D) cannabis use frequency and transitions in ENDS use among young adults.

Perceived social isolation is a key predictor of college students' problematic social networking site use (PSNSU). According to the Fear-Driven/Compensation-Seeking Hypothesis, reducing the fear of social isolation and compensating for social deficits serve as negative reinforcement motivations for SNS use, which may potentially result in PSNSU. This study investigated the association between perceived social isolation and PSNSU through the mediating roles of intentional self-regulation and parasocial relationships from a compensatory perspective. Additionally, gender differences in the mediating model were examined. Findings from an online survey of 893 college students in China revealed a positive relationship between perceived social isolation and PSNSU. The serial mediation model showed that intentional self-regulation and parasocial relationships both had positive individual mediating effects, as well as a negative serial mediating effect. Moreover, these mediating effects were only significant among women. The findings suggest that in the association between perceived social isolation and PSNSU, the mediating role of intentional self-regulation forms a constructive compensatory process, while its serial mediating role through parasocial relationships forms a pathological compensatory process. Interventions for PSNSU should take the mediating role of intentional self-regulation in constructive compensation process and the gender difference into consideration.

This study examines the interplay between problematic internet gaming (PIG) and depressive symptoms among university students, specifically anhedonia and depressed mood. Prior studies lacked distinction between these symptoms and had limited follow-ups.

Gambling is connected to a range of harms and negative consequences. Gambling is also evolving at a fast pace, particularly in digital environments. Understanding the effects of this on-going change and digitalisation of gambling markets requires systematic measuring of gambling consumption patterns, clinical characteristics, and gambling-related harms. The current study compares two cohorts of help-seekers for gambling in Sweden (2019; 2023), recruited via the Swedish national helpline. The aim is to assess harms and consumption across the two cohorts at a time of increased offer of digital gambling in Sweden. We used eight different screens to measure gambling-related behaviours and consequences, including the Gambling Disorder Identification Test (GDIT). Results were analysed using descriptive statistics, and differences across the two cohorts were tested for statistical significance. The results show that across 2019-2023, gambling consumption has intensified. Online EGMs are by far the most prevalent form of gambling among help-seekers. We also found that the experience of co-morbidities as well as most gambling-related harms were common in both cohorts, with some statistically significant increases in 2023. Harms were more commonly experienced amongst those who engaged in online EGM gambling in comparison to those who did not. The results suggest that the digitalisation of gambling and gambling products appears to be associated with a variety of harmful consequences. The results also show the importance of systematic and comprehensive measurement to capture different severity levels of harms and their wide range amongst those who gamble.

The escalating trends in poly-tobacco use among young people are worrying due to the heightened health consequences associated with use. This study aims to re-analyze data from a smoking reduction intervention applying latent transition analysis (LTA) to explore the effect of a smoking reduction intervention on the transition between tobacco and nicotine use behavior patterns, particularly poly-tobacco use, over time. Additionally, the effect of sociodemographic variables on transition patterns was explored.

Cannabis use disorder is common among young adults in psychiatric care, particularly those at risk for psychosis. Yet, interventions tailored to address this issue are limited. The goal of this qualitative study was to determine barriers and facilitators for reducing/quitting cannabis use, and to obtain end-user perspectives to inform a mobile app-based intervention. Twenty young adults (60% female) at high-risk for psychosis who use cannabis completed a brief survey and individual qualitative interview. Results of thematic analysis revealed five barriers (i.e., cannabis to cope, social influences, dependence symptoms, easy access, ambivalence about change) and four facilitators (e.g., experienced/feared consequences, focusing on motivation, social support, coping skills) to cutting down/quitting cannabis. Regarding mobile intervention development, participants recommended high-level personalization and content features such as goal setting, self-monitoring, coping skills, and affirming messages. Additionally, they suggested the intervention be visually appealing and interactive. To assist high-risk youth in reducing/quitting cannabis use, it is important to consider the unique barriers they face in doing so, as well as their specific preferences for the development of a mobile intervention.

Although there is a growing awareness of the co-occurrence of internet gaming disorder (IGD) with other mental health problems, the specific patterns of how these symptoms interact over time, especially across different age groups, remain unclear. The current study utilizes cross-lagged panel network modeling (CLPN) to investigate the dynamic, longitudinal relationships among symptoms of IGD, depression and anxiety among adolescents across time, and how these connections change with different developmental stages. A total of 3296 middle and late adolescents who have finished 3-time points research were included in the present study. Significant differences were found between middle and late adolescents in the structures and strengths of the contemporaneous and longitudinal networks. For middle adolescents, symptoms tended to predict subsequent symptoms within the same disorder. However, late adolescents showed a stronger trend of symptoms being interconnected across comorbid conditions. Feelings of worthlessness & hopelessness were the most impactful symptoms for middle adolescents in the short term and they continued to significantly affect late adolescents in the long term. In addition, restless and suicide or self-harm were the most important bridge symptoms for middle and late adolescents, respectively. This study emphasizes the importance of developing targeted intervention strategies focusing on both central and bridging symptoms of the comorbid conditions of IGD, depression, and anxiety in adolescence. Recognizing distinct adolescents' needs, interventions should be tailored to effectively address the unique challenges at different developmental stages.

Adolescents and young adults continue to access e-cigarettes despite regulatory efforts to prevent sales to those under 21. Prior research on sources of acquiring e-cigarettes excludes key online sources. This study aims to update evidence on where and how different age groups (adolescents, young adults, and adults) access e-cigarettes.

Smoking is prevalent among individuals receiving methadone treatment. Reducing smoking among this population is needed as smoking is a leading cause of morbidity and preventable death. Smoking cessation interventions for persons receiving medication for opioid use disorder have yielded small changes in abstinence. Bupropion-SR was developed as an anti-depressant medication and is a first-line medication for smoking cessation. There is limited research on the effectiveness of bupropion-SR on smoking cessation among individuals receiving medication for opioid use disorder. This study is a secondary analysis of N = 72 adults enrolled in methadone treatment who endorsed smoking cigarettes. Participants were randomized to receive bupropion-SR 150 mg twice-daily (n = 35) or placebo (n = 37) in the primary study that examined bupropion-SR on cocaine use outcomes over a 30-weeks. Mixed model analyses examined secondary changes in self-reported cigarettes smoked, a self-reported measure of nicotine dependence, and quantitative urinary cotinine values. The longitudinal analysis of self-reported daily cigarettes identified no main effects of group and week however a significant interaction between group and week revealed that persons receiving bupropion-SR group reported less smoking early in the intervention. Longitudinal evaluation of changes in urinary cotinine revealed a significant main effect of week but no main effect of group or group x week interaction. Data suggest that bupropion-SR significantly decreased the number of self-reported cigarettes smoked relative to placebo and reduced nicotine dependence severity by the end of the study. Follow-up studies are needed as these decreases were not identified throughout the full study period or at termination.

There is ongoing concern about the impact of increasing use of social media and digital devices on unhealthy behaviors such as substance use in youth. Mobile phone and social media use have been associated with substance use in adolescent and young adult samples, but few studies have evaluated these relationships in younger samples.

E-cigarette use is associated with subsequent cigarette smoking among youth. The current study examined the mediating role of social-cognitive factors in this association.

Research has demonstrated positive associations between adverse childhood experiences (ACEs) and substance use behaviours in young adults. However, many of these are based on cross-sectional data. The pathway between ACEs and substance misuse among emerging adults is also not fully understood and few studies have investigated potential mediating factors.

Based on the Interaction of Person-Affect-Cognition-Execution model and the risk-buffering model, the current study explored how and when rumination increases problematic mobile phone use (PMPU) among Chinese female freshmen. Specifically, we investigated the underlying mechanism of PMPU by testing a moderated mediation model in which solitude capacity moderated the mediating role of fear of missing out (FoMO) in the relationship between rumination and PMPU. A sample of 1,389 female freshmen in China, with a mean age of 19.68 years (SD = 2.63), was surveyed using the Rumination Response Scale, Fear of Missing Out Scale, Solitude Capacity Scale, and Mobile Phone Addiction Index. Mediation analysis indicated that rumination increases female freshmen's PMPU by heightening FoMO. Moderated mediation analysis further demonstrated that high capacity for solitude mitigated the adverse effects of FoMO on PMPU among female freshmen, whereas low capacity for solitude exacerbates the negative impact of FoMO on PMPU in this group. This study highlights the mediating and moderating mechanisms linking rumination to PMPU. More importantly, it has significant implications for the prevention and intervention of PMPU among female freshmen.

People with trauma histories have an increased odds of cannabis use. Little is known about the frequency or consequences of different cannabis use regimens in cannabis users with trauma histories. Individuals with anxiety disorders tend to administer benzodiazepines in a pro re nata (PRN; i.e., as needed) as opposed to regularly scheduled (RS, e.g., twice daily [BID], three times daily [TID]) manner. Although physicians tend to prescribe benzodiazepines on a PRN regimen to minimize use, this regimen is paradoxically associated with greater use levels. Indeed, PRN administration regimens may increase use via negative reinforcement processes. We extended this older benzodiazepine literature to cannabis by examining regimen of cannabis use among 94 trauma-exposed cannabis users (mean age = 35.1 years; 52.1 % male; 23.4 % with cannabis prescription). Participants reported their initial and current cannabis use regimen (PRN vs. RS vs. both ['PRN+']) and their past month cannabis use frequency (use occasions in last month) and quantity (grams/use occasion). Consistent with patterns in benzodiazepine research, PRN (47.1 % of sample) and PRN+ (43.5 % of sample) were more common than RS regimens (9.4 % of sample). Also consistent with patterns seen with benzodiazepines, our sample moved toward PRN regimens from initial to current use: e.g., 100 % of initial RS users switched to a regimen that included PRN use. Consistent with predictions emerging from learning theory, PRN and PRN+ cannabis users reported significantly higher cannabis use frequencies compared to RS users (p's < 0.01). Unexpectedly, there were no significant differences between cannabis use regimen groups for quantity of cannabis/occasion. While limited by their cross-sectional nature, with longitudinal replication, result may have implications for identifying cannabis use regimens that minimize frequency of use and thereby reduce risk for negative health outcomes.

Using the Elaborated Intrusion Theory of Desire and the Self-Regulatory Executive Function model of psychopathology as bases, this study explored whether metacognitive beliefs and desire thinking (DT) are associated with higher levels of Compulsive Sexual Behavior (CSB). A total of 1185 participants from the general population were included in the study (mean ± SD age = 25.32 years ± 5.58; age range = 18-19 years; females = 76.7 %). Metacognitive beliefs, DT, CSB, anxiety and depressive symptoms were assessed. Correlation analyses and path analyses were run. Results of the path analysis showed that positive metacognitive beliefs about DT were associated with DT-Imaginal Prefiguration (DT-IP), which in turn was positively associated with DT-Verbal Perseveration (DT-VP). The latter was strongly and positively associated with negative metacognitive beliefs about DT, which in turn was linked to CSB. Moreover, DT-VP was also found to be directly linked to the outcome variable and positive metacognitive beliefs about DT were also directly linked to DT-VP and negative metacognitive beliefs about DT. The total Coefficient of Determination (0.45) indicated a good fit to the observed data. Metacognitive beliefs and DT may be potential maintenance factors in CSB. Metacognitive beliefs and DT could also be considered as potential therapeutic targets in clinical interventions aimed at reducing the severity of CSB.

A cognitively demanding, alcohol-specific inhibition training (Alc-IT) might enhance treatment success in patients with severe alcohol use disorder (AUD; Stein et al., 2023). An inhibitory working mechanism for Alc-IT has been discussed, but compelling evidence supporting this hypothesis is yet lacking. The present study investigates inhibitory performance during Alc-IT and examines whether inhibitory parameters mediate drinking outcome.

Few studies have estimated the frequency of e-cigarette use by smoking status among French young adults, and how those who smoke tobacco start and continue to use e-cigarettes. Our aim was to describe e-cigarette use among students who smoked tobacco.

Cannabis is the most used federally illicit drug in the United States (U.S). Understanding how accurate adolescents and emerging adults are at estimating their cannabis use quantity is important, as this lays the groundwork for understanding and studying the outcomes associated with cannabis use. This study aimed to assess the accuracy of cannabis quantity in grams for a typical joint and identify predictors of accuracy among U.S. adolescents and emerging adults. Participants (n = 50; aged 14-21) who reported using joints in the past 30 days completed measures of cannabis use characteristics and problems, were asked to "eyeball" the amount of cannabis in their average joint using a cannabis substitute and estimated the number of grams. The cannabis substitute was then weighed in grams. Paired samples t-tests indicated that participants estimated significantly more grams in a joint (M=.82; SD = 0.46) than the actual amount of the surrogate substance (M=.47; SD = 0.21; t(49) = 6.32, p < 0.001, d = 0.89). A linear regression analysis indicated that the age of cannabis initiation (B = -0.13, p=.002) and cannabis use problems (B = -0.03, p=.009) were negatively and significantly associated with discrepancies in estimated grams. Specifically, being older when first using cannabis and reporting more cannabis use problems were linked to less overestimation of grams per joint. These findings align with previous research demonstrating a tendency to overestimate cannabis quantity and contribute novel insights by identifying predictors of estimation accuracy. This study underscores the importance of considering age and cannabis-related problems when assessing the reliability of self-reported cannabis use quantities among adolescents and emerging adults.

Given the many nicotine and tobacco products in use, studies of the interdependence of use patterns and transitions are needed.

Smoking cessation at any age has been shown to improve quality of life, decrease illness, and reduce mortality. About half of smokers attempt to quit each year, but only ∼ 7 % maintain long-term abstinence unaided. Few genetic factors have been consistently associated with smoking cessation, possibly due to poor phenotype definition.

Self-regulation strategies, such as limit setting, can be effective in reducing harms associated with gambling. However, limited research has examined their applicability to in-play sports betting. The current study therefore examined the utility of self-regulation strategies in reducing in-play betting intensity and associated harms. Adults engaging in-play betting (N = 77; M = 41.23 years, 71.43 % men) completed 14 days of ecological momentary assessment surveys in which they reported their in-play betting behaviours (number of bets placed, money spent), use of self-regulation strategies for in-play betting (setting monetary limits, setting time limits, stopping betting when no longer fun, taking frequent breaks), and in-play-betting-related harms. Multilevel models revealed that participants with a greater propensity to set monetary limits were overall less likely to experience financial, interpersonal, and health harms. In addition, participants were less likely to experience emotional/psychological harms following in-play betting occasions during which they set monetary limits (versus when they did not). In contrast, participants with a greater propensity to set time limits tended to spend more money on in-play bets, experienced more harms on average, and were overall more likely to experience financial and work/study harms. Results provide preliminary support for the utility of monetary limit setting, but not time limit setting, in reducing in-play-betting-related harms. Findings support the applicability of select self-regulation strategies originally proposed for more traditional forms of gambling to in-play sports betting, and highlight a need for further research investigating whether other responsible gambling strategies may be effective in reducing in-play-betting-related harms.

Effective gambling messages should curb time and money spent on gambling, since these are the behaviours proximal to gambling-related harm. Studies that aim to find what messages best achieve these objectives are scarce, and most focus on electronic gaming machine (EGM) gambling rather than sports and race betting. The present study aimed to gather longitudinal evidence on previously identified messaging strategies. In an experiment, two types of messages, positive-emotional and norm-based, were contrasted against a control condition with generic messages (e.g., gamble responsibly). By stratified random assignment, participants (N = 2,074, 36% female), were exposed to 3 unique messages in each of 3 weeks, exclusive of pre- and post-surveys in weeks 1 and 5, respectively. There were no significant differences by condition in amounts-bet commercially on sports or race betting, time spent gambling, gambling-harm experienced, gambling-urges nor risk-related gambling beliefs. However, there was a significant decrease in all these outcomes over weeks 1 through 5. The messages may not have been the factor that contributed to the decrease in outcomes over time, as participating in the study may have also prompted self-reflection on gambling expenditure. Positive-emotional messages were rated most helpful and easily understood, and the highest-rated message was the control message, "only bet what you can afford." Despite no differences found between the conditions, the present study provided evidence that self-reflection on gambling expenditure is well-rated by gamblers as being helpful. Future experiments should be conducted to gauge the robustness of this finding.
