Perceived stress is considered a significant risk factor for Internet gaming disorder (IGD). However, the longitudinal dynamics and the underlying mechanisms of this relation remain underexplored. Drawing on the Compensatory Internet Use Theory, this study examined the mediating role of depressive symptoms in the longitudinal relation between perceived stress and IGD among adolescents. A total of 1567 Chinese adolescents (44.9 % boys; Mage = 15.41, SD = 0.51 at baseline) participated in a three-wave longitudinal study with a six-month interval. Cross-lagged panel modeling revealed that: (a) significant bidirectional relations were observed between perceived stress and depressive symptoms (βs ranged from 0.19 to 0.22, ps < 0.001); (b) depressive symptoms positively predicted subsequent IGD (βs ranged from 0.14 to 0.16, ps < 0.001); and (c) depressive symptoms mediated the relation between perceived stress and IGD (indirect effect = 0.032, 95 % CI [0.007, 0.062]). These findings highlight the critical role of depressive symptoms in the progression from perceived stress to IGD. Addressing depressive symptoms may be crucial for preventing and intervening with adolescent IGD.

With the global rise in smartphone use, problematic smartphone use (PSU) has emerged as a critical mental health concern. While reinforcement pathology theory posits that a high expected value of alternative behaviors (EVAB; e.g., psychological rewards from social or physical activities) may mitigate addictive tendencies, no prior study has examined this hypothesis in daily life contexts. This study is the first to investigate the within-person dynamics of EVAB on PSU and its underlying mechanisms. Using ecological momentary assessment (EMA), 72 participants (Mage = 19.01 ± 0.93 years; 40 females) completed baseline measures of episodic future thinking (EFT) followed by 14 days of intensive longitudinal data collection (three daily reports), assessing EVAB, delay discounting, PSU, and screen time. Dynamic structural equation modeling (DSEM) revealed two key findings: First, momentary increases in EVAB predicted subsequent reductions in both PSU levels and screen time, mediated by decreased delay discounting (β = -0.032, HPD 95 % CI = [-0.051, −0.014]). Second, individual differences in EFT detail/vividness and mental imagery positively predicted daily EVAB, which in turn reduced PSU via lower delay discounting (β = -0.015, HPD 95 % CI = [-0.026, −0.006]; β = -0.012, HPD 95 % CI = [-0.022, −0.004]). These results provide the first empirical support for core hypotheses of reinforcement pathology theory in PSU research, elucidating the dynamic role of EVAB while offering novel theoretical and clinical insights. The findings emphasize that PSU interventions should target both within-person fluctuations in reinforcement valuation and between-person differences in future-oriented cognition.
随着全球智能手机使用量的增加，智能手机使用问题（PSU）已成为一个重要的心理健康问题。虽然强化病理学理论认为，替代行为（EVAB，如来自社会或身体活动的心理奖励）的高期望值可能会减轻成瘾倾向，但之前没有研究在日常生活环境中检验这一假设。这项研究首次探讨了EVAB对PSU的人体内动力学及其潜在机制。使用生态瞬间评估（EMA）， 72名参与者（年龄= 19.01±0.93岁；40名女性）完成了情景未来思维（EFT）的基线测量，随后进行了14天的强化纵向数据收集（每日三次报告），评估了EVAB、延迟折扣、PSU和屏幕时间。动态结构方程模型（DSEM）揭示了两个关键发现：首先，EVAB的瞬间增加预示着PSU水平和屏幕时间的随后减少，这是由延迟折扣减少介导的（β = -0.032, HPD 95% CI =[-0.051, -0.014]）。其次，EFT细节/生动度和心理意象的个体差异正预测每日EVAB，进而通过较低的延迟折扣降低PSU （β = -0.015, HPD 95% CI = [-0.026, -0.006]; β = -0.012, HPD 95% CI =[-0.022, -0.004]）。这些结果为PSU研究中强化病理学理论的核心假设提供了第一个实证支持，阐明了EVAB的动态作用，同时提供了新的理论和临床见解。研究结果强调，PSU干预应针对强化评估的个人内部波动和面向未来的认知的个人之间差异。

Background: Substance use is commonly documented among human trafficking (HT) survivors in emergency department (ED) settings. Multiple substance use disorders (poly-SUD) are associated with poor health and psychosocial outcomes. This study identified latent classes and demographic covariates of HT-related ED visits by the types of SUDs documented in survivors’ medical records. Methods: We used cross-sectional data from the United States 2019–2021 Nationwide Emergency Department Sample, including visits of patients aged 12–64 years with an ICD-10-CM code documenting either sex or labor exploitation (N = 4,212). A bias-adjusted three-step latent class analysis was conducted, with SUDs documented via ICD-10-CM codes included as indicators in the model. Results: The optimal three-class solution had superior fit based on pre-selected indicators, low classification error, and acceptable entropy. The largest class comprised 76.01 % of the sample and showed a lower predicted probability of the SUD classes considered. The second largest class (17.27 %) was characterized by high predicted probability of stimulant use disorder with moderately high predicted probability of opioid use disorder. The smallest class (6.72 %) was characterized by high predicted probability of each SUD considered. Class membership was differentially associated with disposition from the ED, nicotine use disorder, and income. Conclusions: Although most ED visits were classified as having relatively low probability of SUD, nearly one quarter of the sample had high risk of either stimulant use disorder or high poly-SUD. Poly-SUD in HT survivors is associated with increased risk of hospitalization. Findings provide direction for tailoring intervention programs to support SUD recovery among HT survivors.

Examining why adolescents and young adults post or delete alcohol-related content on social media has important implications for understanding and mitigating the influence of alcohol-related social media content on alcohol cognitions and use. This longitudinal study explored motives for posting and deleting alcohol content and their association with actual posting and deleting one month later. Survey data were collected from 306 adolescents and young adults recruited as part of a longitudinal experimental study examining alcohol-related content on social media and alcohol norms and use. Participants aged 15–20 (M = 18.39; SD = 1.32) indicated the top three motives for posting alcohol content: prove they were having fun, show they have an active social life, and make themselves look cool. The most endorsed motives for deleting alcohol-related social media content included: it being unflattering, feeling embarrassed, or fear of others sharing it. After controlling for relevant covariates, a negative binomial regression indicated that at baseline, alcohol-related posting motives related to making others jealous, posting about most things, and doing what friends do were significantly and positively associated with frequency of posting alcohol-related content one month later. Further, results of a linear regression indicated that the only baseline motive significantly associated with frequency of deleting alcohol-related content at 1-month follow-up was finding the content unflattering. Overall, results suggest that there are unique motives associated with both posting and deleting alcohol-related content on social media, which has implications for preventative interventions aiming to reduce alcohol-related social media behavior.

Background
Professional societies recommend that adolescents with opioid use disorder (OUD) receive medication for opioid use disorder (MOUD). This cross-sectional study examined the association between adolescent specialty treatment episodes for OUD with planned MOUD use compared to adults over time.
Methods
We used data on first episodes of specialty treatment for OUD (n = 671,183) from the Treatment Episode Data Set – Admissions, a national database of publicly funded treatment programs in the US Admissions occurred between 1/2017–12/2022. The primary exposure was being adolescent (15–17 years). The main outcome was planned MOUD use, defined as having MOUD in a treatment plan.
Results
Adolescent specialty treatment episodes for OUD were significantly less likely to have planned MOUD use than adults (aOR 0.05, 95% CI, 0.02–0.09). Linear combination tests of the interaction between age group and year confirmed that adolescent episodes were significantly less likely to have planned MOUD use than adults across all years. In 2021 and 2022 this disparity narrowed slightly. In 2021, adolescent episodes had 10% of the adjusted odds of planned MOUD use compared to adults in 2017 (95% CI, 0.07–0.15). In 2022, adolescent episodes had 9% of the adjusted odds of planned MOUD use compared to adults in 2017 (95% CI, 0.06–0.11).
Conclusion
Adolescents entering specialty treatment for OUD had significantly lower odds of planned MOUD use than adults. The relatively smaller difference between adolescents and adults in recent years suggests a potential trend toward greater MOUD access, though future research is needed to understand access barriers.

Prior studies suggest that TikTok users vary in their engagement behaviors, including passive viewing, participatory interaction, and content creation, and exhibit varying levels of problematic-use risk. Yet it remains unclear which combinations of these engagement behaviors correspond to higher versus lower risk, and which psychological vulnerabilities contribute to high-risk patterns. In a two-wave study of 715 Chinese young adults, we applied latent profile analysis (LPA) to problematic TikTok use and the frequency of passive viewing, participatory, and contributory behaviors at Time 2. We then used multinomial logistic regression with the three-step method to prospectively examine how Time 1 measures of psychopathology and related affective/cognitive vulnerabilities, including depression, social anxiety, life satisfaction, emotion dysregulation, and boredom proneness, predicted TikTok profile membership. Four profiles emerged: Minimal Users (6.7 %), Passive Watchers with High Problematic Use Tendencies (38.0 %), Moderate Users with Mild Problematic Use Tendencies (42.4 %), and Active Users with Low Problematic Use Tendencies (12.9 %). Greater life satisfaction, lower social anxiety, and lower boredom proneness at baseline predicted membership in the Active rather than Passive, Moderate, or Minimal profiles. Greater emotion dysregulation predicted membership in the Passive rather than Moderate profile. These findings highlight substantial heterogeneity in TikTok use and suggest that higher baseline psychological wellbeing may increase the likelihood of more active and less problematic patterns of engagement. The current study extends prior LPA research by specifying how risk manifests in everyday use, identifying contributors to high-risk profiles, and extending empirical support for the I-PACE theoretical framework of Internet use disorders.

No previous studies have ever examined humor as a diffusion strategy in the context of technology use. The present study is the first to investigate whether meta-inner humor beliefs (MIHBs) are prospectively associated with problematic social media use (PSMU) via metacognitions about social media use. A prospective, two-wave longitudinal design with a bidirectional cross-lagged panel (CLPA) model was used to examine associations between adaptive and maladaptive MIHBs on PSMU, examining the indirect pathway of positive and negative metacognitions about social media use (meta-SMUs). The study was conducted across two waves at a six-month interval. At Wave 1, a large community sample (N = 1,253; 58.2 % females; age = 36.8 years [SD ± 14.1]) participated in the study, and at Wave 2, 78.1 % of the starting sample completed the follow-up assessment. Results from the bidirectional CLPA showed that adaptive MIHBs at Wave 1 were significantly associated with lower negative and positive meta-SMUs at Wave 2. In contrast, maladaptive MIHBs were only associated with higher negative meta-SMUs at Wave 2. Also, negative meta-SMUs predicted an increase in PSMU six months later, whereas it was non-significant for positive meta-SMUs. Analyses of bidirectional indirect pathways demonstrated that adaptive MIHBs were indirectly related to lower PSMU through reduced negative metacognitions, while maladaptive MIHBs were indirectly related to higher PSMU through elevated negative metacognitions. Multi-group analyses established full longitudinal measurement and structural invariance across gender. The findings underscore the potential role of humor-related metacognitive pathways in the maintenance of PSMU, suggesting that humor-based psychotherapeutic approaches warrant further investigation.

The findings underscore the potential role of humor-related metacognitive pathways in the maintenance of PSMU, suggesting that humor-based psychotherapeutic approaches warrant further investigation.</div></div>","PeriodicalId":7155,"journal":{"name":"Addictive behaviors","volume":"173 ","pages":"Article 108551"},"PeriodicalIF":3.6,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145508293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

Anxiety as a broad construct has been linked to nicotine craving, frequency of use, and relapse rates. However, there is limited research on the relationship between state anxiety and nicotine craving. This study explored the association between state anxiety and pre-cue versus post-cue craving among adults who use nicotine and tobacco products (NTPs) at different frequencies. Participants with either non-daily (n = 34) or daily (n = 80) NTP use completed a laboratory assessment including a virtual reality (VR) NTP cue-exposure paradigm and self-report assessments of state anxiety and nicotine craving. NTP use group membership was a significant predictor of pre-cue and post-cue craving, with daily NTP users exhibiting greater pre-cue (p = 0.001) and post-cue (p < 0.001) craving than non-daily users. State anxiety was positively associated with pre-cue craving (p = 0.03) but not post-cue craving. Notably, non-daily users showed a significant negative relationship between state anxiety and post-cue craving (p = 0.01). The results of this study suggest that NTP use (especially daily use), and state anxiety are more strongly associated with pre-cue craving, as opposed to post-cue-induced craving. This study provides insight into how the relationship between state anxiety and nicotine craving varies pre and post cue-exposure, which may inform treatment and intervention efforts targeting transient affective states to prevent or reduce nicotine craving.

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.
