The associations between problematic social media use (PSMU), depression, and social anxiety (SA) remain a topic of debate. Hence, this study investigated the bidirectional longitudinal relationships of PSMU with depression and SA in a sample of Chinese university students, with an additional emphasis on potential sex differences. A total of 378 students (56.3 % male, 43.7 % female; Mage = 20.49 years, SD = 0.65) completed three waves of survey data. Random Intercept Cross-lagged panel model analysis and multi-group analysis by sex were conducted. At the within-person level, a reciprocal relationship was observed between PSMU and depression over time. Furthermore, SA predicted later increases in PSMU, whereas the reverse associations were not significant. These results highlight the dynamic interplay among emotional symptoms and digital behavior, and underscore the importance of considering both individual differences and temporal fluctuations in future research.

Gambling-related harms significantly impact not only gamblers but also people socially connected to them (affected others or AOs), yet quantifying these impacts has remained challenging. This study developed and validated two scales for measuring harm to people due to someone else’s gambling − the 10-item and 20-item Gambling Harms Scale for Affected Others (GHS-10-AO and GHS-20-AO) − benchmarked to health utility metrics. Using data from 2,018 Australian adults with close relationships to gamblers, we employed psychometric item selection, propensity weighting, and control for comorbidities to establish evidence for causal links between reported harms and health utility decrements measured by the SF-6D. Emotional, relational, and financial harms were the most prevalent items selected. Both scales demonstrated excellent reliability (α = 0.89 for GHS-10-AO; α = 0.94 for GHS-20-AO) and strong correlations with health utility measures (r = -0.47 to −0.48 with SF-6D). The relationship between harm scores and health utility showed significant non-linearity, with increasing convexity at higher harm levels. These scales provide the first validated instruments for quantifying health impacts to AOs using a common metric comparable to gambler-focused harm measures, enabling population-level assessment of current gambling harm in the adult population; inclusive of gamblers and connected others. The instruments fill a critical gap in gambling harm measurement and offer jurisdictions tools for monitoring progress toward harm minimisation that encompasses impacts on both gamblers and those around them.

The increasing use of smartphones has raised concerns about adverse psychological and social-cognitive outcomes among young people. This study aimed to prospectively examine the relationships between problematic smartphone use (PSU), experiential avoidance (EA), screen time, autistic traits (ATs), and theory of mind (ToM), and to test the mediating role of EA within a temporal design. Data were collected prospectively from 219 young adults (aged 18–35; M = 20.66, SD = 2.15) across three measurement points at one-week intervals. At Time 1 (T1), participants reported their weekly screen time and completed baseline measures of PSU, ATs, and ToM. At Time 2 (T2), the measure of EA was administered. At Time 3 (T3), final measures of ATs and ToM were administered. The results indicated that higher levels of PSU at T1 prospectively predicted an increase in EA at T2, which in turn prospectively predicted higher levels of ATs and lower levels of ToM at T3. Similarly, greater screen time at T1 also prospectively predicted an increase in EA at T2, leading to higher levels of ATs and lower levels of ToM at T3. The results indicate that experiential avoidance prospectively plays a mediating role in the relationship between PSU, screen time, ToM, and ATs. In the context of today’s increasing digital addiction tendencies, these findings suggest that EA is a potentially important transdiagnostic variable to consider in assessments and interventions aimed at supporting socio-cognitive and emotional functioning.

Background
Gaming disorder is a new addictive disorder under the ICD-11. Most of recent research focuses on young people and its impact on mental and physical health. However, it can also have negative financial impacts as in-game microtransaction and esport betting becoming more common, and this impact could be particularly problematic for older people. This study estimates the association between gaming disorder and game-related overspending.
Method
Data were from the 2022 International Gaming Study (IGS22), a multi-country cross sectional survey of 955 individuals aged 18–94 (M = 46; SD = 16; 45 % Male). We estimated the proportion of participants who reported game-related overspending and modelled its association with ICD-11 Gaming Disorder using logistic regression.
Result
In general, a much smaller but non-negligible proportion of older people (66 years old + ) reported various type of game-related overspending (4 – 9 %) compared to younger age groups. Individuals who are at risk of gaming disorder were at six to nine times higher odds of reporting various type of gaming-related overspending.
Conclusion
This study reveals a novel association between gaming disorder and overspending on purchasing games, in-game purchases, and esports betting across various age groups. While young individuals were more likely to report overspending, some older adults were also affected. As the measure reflects self-reported overspending, further research is needed to assess whether this translates into actual financial hardship.

Background
E-cigarette use has grown in popularity and is independently associated with alcohol use and mental health (anxiety/depression), but the interactions between alcohol and anxiety/depression with e-cigarette use have not been examined. We examined whether anxiety/depression would influence the association of both alcohol use frequency and heavy episodic drinking (HED) with e-cigarette use frequency, hypothesizing that alcohol use would be more strongly related to e-cigarette use among those with current anxiety/depression.
Methods
N = 11,006 adults (55 % female; 71 % non-Hispanic White, M age = 42) completed assessments of demographics, past 30-day e-cigarette and alcohol use, and current symptoms of anxiety and depression. Regression models including past 30-day e-cigarette users only (N = 2,395) examined the moderating effects of anxiety/depression (yes/no) on the alcohol-e-cigarette frequency relationship, examining alcohol use frequency and HED separately.
Results
More than one-fifth (21.7 %) of the total sample reported any past 30-day e-cigarette use. Among e-cigarette users, past 30-day alcohol use frequency was associated with e-cigarette use frequency but did not significantly differ by mental health status (IRR = 1.02, 95 % 1.01, 1.02). HED was not associated with e-cigarette use frequency, regardless of mental health status (IRR = 1.02; 95 % CI: 0.93, 1.11).
Conclusion
The relationship between current alcohol use and e-cigarette use frequency was not statistically different between individuals who endorsed current anxiety and/or depression vs. those who did not. Findings support the need to consider other substance use within e-cigarette smoking prevention and cessation efforts. Additional longitudinal research is needed to infer directionality and causality.

Introduction
Prior research shows that in-person exposure to electronic nicotine delivery systems (ENDS) use increases desire for both cigarettes and ENDS. Distinct from nicotine ENDS use, cannabis vaping is on the rise, often in conjunction with nicotine vaping or combustible cigarettes, marking a need to understand how co-use impacts ENDS cue reactivity. This study leverages a remote cue-delivery paradigm to evaluate the impact of co-use of cigarettes and cannabis on reactivity to a remote ENDS cue.
Methods
A cannabis co-use group (N = 45, individuals who smoke cigarettes and vape cannabis) and a non-co-use group (n = 61, individuals who smoke cigarettes and do not vape cannabis) observed a study confederate drinking bottled water (control cue) and vaping an ENDS (active cue). Desire to use a cigarette, ENDS and cannabis were measured before the cues (baseline), post-water and post-ENDS cue.
Results
Multilevel models, controlling for sex and weekly ENDS use, examined cue reactivity across the co-use and non-co-use groups. Those who vaped cannabis in the past year reported both higher baseline ENDS and cannabis desire and heightened responses to the ENDS cue such that cue exposure significantly increased their desire for cigarettes, ENDS and cannabis.
Conclusions
This study provides the first evidence for differential ENDS cue-elicited desire in those who smoke cigarettes and vape cannabis. These findings suggest that co-use of cannabis and cigarettes may increase vulnerability to cravings, indicating a need for tailored prevention and intervention strategies for individuals who use both substances.

Brief mindfulness meditation induction effectively reduces addictive behaviors in clinical populations, yet their impact on non-addicted individuals remains unclear. This study investigated whether brief mindfulness practice amplifies alcohol enjoyment and consumption in healthy young adults. Across two randomized controlled trials (Study 1: N = 67; Study 2: N = 89), participants with low-risk drinking profiles completed a 16-minute mindfulness induction or a neutral control task, followed by alcohol tasting and behavioral measures. Results revealed that mindfulness significantly enhanced subjective alcohol enjoyment (Study 1: d = 0.45, p = 0.01; Study 2: d = 0.45, p = 0.04) and increased positive affect while reducing negative emotion (d = 0.95–1.20, p < 0.001), but did not alter actual consumption. An Implicit Association Test (IAT) in Study 2 showed no group differences in implicit attitudes toward alcohol versus tea. These findings indicate that brief mindfulness may intensify affective and sensory responses without increasing use—possibly due to a dissociation between reward sensitivity and behavioral impulse. The results align with dual-process theories of mindfulness (e.g., Monitor and Acceptance Theory, Mindfulness-to-Meaning Theory), and highlight the importance of aligning mindfulness practices with motivational and regulatory goals to avoid unintended reinforcement of substance-related pleasure in non-addicted populations.

Rationale: Impaired control over alcohol use is a core aspect of Alcohol Use Disorder symptomatology. However, research regarding how impaired control manifests at the day-level, and what temporally proceeds it in daily life, remains underdeveloped. The current study tested whether three aspects of impaired control, namely restraint difficulties, drinking more than planned, and drinking longer than planned, had shared versus unique variability within- and between-individuals, and if pre-drinking positive and negative affect predicted such variability.
Methods
College students (N = 256) completed 14-days of ecological momentary assessment. Morning surveys assessed prior-day drinking, and random surveys assessed positive/negative affect, drinking behavior, and impaired control. Multilevel models tested the structure of day-level impaired control items within- and between-individuals and their pre-drinking affective antecedents.
Results
At the within-person level, day-level restraint difficulties, drinking more than planned, and drinking longer than planned loaded well onto a latent factor, whereas between-person drinking more than planned loaded onto a latent factor highly but restraint difficulties and drinking longer than planned did not. Pre-drinking affect did not predict latent factors at either level. However, when specifying items as correlated outcomes, deviations in pre-drinking positive and negative affect predicted drinking more than planned at the within-person level and person-aggregated pre-drinking negative affect predicted restraint difficulties at the between-person level. Findings did not differ as a function of hazardous drinking.
Conclusions
Findings demonstrate complexities of modeling impaired control items within- and between-individuals and suggest that pre-drinking affect was related to drinking more than planned and restraint difficulties, albeit in different ways.

Background
Adolescence is a critical period for substance use initiation, with consequences for addiction and psychosocial problems in adulthood. However, differences in initiation by key variables such as age and racialized/ethnic group remain understudied.
Objectives
This study examined age and peer influence in relation to alcohol, cannabis, and cigarette initiation across eight racialized/ethnic groups (Asian or Pacific Islanders, Black, Indigenous, Hispanic White, White, Biracial White-Asian, Biracial White-Black, and Biracial White-Indigenous) to compare biracial groups with their monoracial counterparts.
Methods
Using integrated data analysis with Add Health (n = 15,844; mean age = 15.6) and Monitoring the Future (MTF; n = 9,600; mean age 18.4), we applied discrete-time survival analysis to estimate initiation hazards during adolescence (ages 12–18), accounting for racialized/ethnic group, sex, and peer substance use.
Results
The hazards for new initiations of alcohol and cannabis followed a quadratic function of age, peaking around ages 16 and 18. Cigarette use initiation, in contrast, had a relatively flat hazard function. Biracial youth typically showed intermediate or higher risk of substance use initiation relative to their monoracial peers depending on the specific subgroups and substances considered. Peer substance use was associated with increased initiation across all groups, with stronger effects during peak initiation ages and variations in magnitude across racialized groups.
Conclusion
Our findings show substance use initiation risks and susceptibility to peer influence differ between biracial and monoracial adolescents and between specific biracial subgroups, highlighting the need to consider subgroup differences when addressing adolescent substance use.
背景：青春期是物质使用开始的关键时期，其后果是成人期的成瘾和社会心理问题。然而，年龄和种族/民族等关键变量在开始治疗方面的差异仍未得到充分研究。目的：本研究考察了8个种族/民族群体（亚洲或太平洋岛民、黑人、土著、西班牙裔白人、白人、白人-亚洲混血儿、白人-黑人混血儿和白人-土著混血儿）中年龄和同伴对酒精、大麻和吸烟的影响，并将混血儿群体与单一种族群体进行比较。方法：使用Add Health （n = 15,844，平均年龄= 15.6）和Monitoring the Future （MTF, n = 9,600，平均年龄18.4）的综合数据分析，我们应用离散时间生存分析来估计青春期（12-18岁）的起始危害，考虑到种族/民族、性别和同伴物质使用。结果：初次接触酒精和大麻的危害遵循年龄的二次函数，在16岁和18岁左右达到峰值。相比之下，卷烟开始使用的危害函数相对平缓。根据所考虑的具体亚群体和物质，混血儿青年相对于单种族同龄人通常表现出中等或更高的物质使用开始风险。在所有群体中，同伴物质使用与开始吸毒的增加有关，在开始吸毒的高峰年龄和不同种族群体的程度差异中，这种影响更强。结论：我们的研究结果表明，在混血儿和单混血儿青少年之间以及特定的混血儿亚群体之间，物质使用的开始风险和对同伴影响的易感性存在差异，这突出了在解决青少年物质使用问题时考虑亚群体差异的必要性。

Background
Cigarette smoking is prevalent among adults with intellectual disability (ID), yet much remains to be understood about their smoking and cessation experiences, contributing to ongoing healthcare inequalities. This study aims to understand smoking experiences and cessation barriers and facilitators among people with ID in residential services, using a multiperspective approach.
Methods
This qualitative study involved 10 adults with ID who smoked cigarettes daily and 10 support professionals purposively recruited from residential services. In-depth face-to-face interviews were conducted to explore experiences of tobacco use and cessation. Data were analyzed using Interpretative Phenomenological Analysis.
Results
Six superordinate themes emerged: (1) smoking initiation as a social behavior and identity construction; (2) current smoking as a daily routine, shared activity, and source of gratification; (3) access to cigarettes and smoking regulation by support professionals; (4) ambivalent motivation to quit, with health concerns as transient triggers; (5) cessation barriers, including risk minimization, social influences, low self-efficacy, and limited knowledge of interventions; and (6) perceived cessation aids, including distraction and social support. Certain support practices—i.e., restricting access to cigarettes or using them as a reward—were experienced as limiting, underscoring tensions between health promotion and autonomy.
Conclusions
Findings highlight the need for rights-based, person-centered cessation approaches for people with ID. Cessation strategies should extend beyond pharmacology to include emotional, social, and environmental dimensions, while aligning with individuals’ values and experiences. Professionals require training to balance health promotion with self-determination. Future interventions should prioritize empowerment and provide tailored, evidence-based support addressing personal and contextual factors.
