This study aimed to examine the variable- and symptom-level relationships between fear of missing out and problematic social media use among early adolescents from Generation Alpha using the random intercept cross-lagged panel model (RI-CLPM) and cross-lagged panel network analysis (CLPN), respectively. A total of 672 Chinese early adolescents participated in a three-wave study with six-month intervals. The RI-CLPM revealed that fear of missing out positively predicted problematic social media use at the within-person level, while problematic social media use positively predicted fear of missing out only from T2 to T3. The CLPN uncovered the strongest cross-lagged edges between fear of missing out symptoms and problematic social media use symptoms. Additionally, several key nodes were identified: social integration showed the highest out-expected influence (OEI) and tolerance showed the highest in-expected influence (IEI) from T1 to T2; withdrawal showed the highest OEI and salience showed the highest IEI from T2 to T3. This study offers theoretical insights into the dynamic interplay between fear of missing out and problematic social media use among early adolescents from Generation Alpha, and practical guidance for effective prevention and intervention to break the vicious cycle.

Sports betting has grown in popularity in recent years in the US and Canada, and is now a major form of gambling. In the present research, we examined which motivations for sports betting mediated the association between emotional vulnerabilities (i.e., anxiety and depression) and sports betting and gambling problems. We recruited sports bettors in Ontario, Canada (final N = 915; 77.2 % men) and categorized them as in-play bettors (n = 221), single-event bettors (n = 531), and traditional bettors (n = 163). Participants completed an online battery of questionnaires measuring depression, anxiety, sports betting behaviour, problem gambling, and sports betting motives. Analyses showed that depression and anxiety were highly correlated in this sample of sports bettors. Both depression and anxiety were associated with greater gambling problems, and these associations were mediated primarily through coping motives. On the other hand, mediation analyses showed that depression and anxiety were associated with greater sports betting frequency primarily through enhancement motives. We also found that the associations did not differ significantly for type of sports betting, nor did they differ between men and women. These results demonstrate that depression and anxiety may be more likely to be comorbid in those who partake in sports betting, and that coping motives are related to gambling problems in sports bettors. Thus, our findings support the pathways model of problem gambling, suggesting that interventions for those who primarily engage in sports betting should focus on comorbid depression and anxiety, and should bolster coping styles.

Objective
This study examined the relationships among physical activity, negative emotions, self-control, and problematic mobile phone use, focusing on mediating mechanisms and the moderating role of specific negative emotions (depression, anxiety, stress, loneliness).
Methods
Meta-analytic structural equation modeling (MASEM) was applied to pooled data from 23 studies (N = 65,507) to estimate direct and indirect effects.
Results
Results revealed significant correlations, with the strongest between negative emotions and problematic mobile phone use (r = 0.484) and the weakest between physical activity and problematic mobile phone use (r = −0.285). Depressive symptoms showed the strongest association with problematic use (r = 0.656), followed by stress (r = 0.599) and anxiety (r = 0.491). MASEM indicated a total effect of physical activity on problematic mobile phone use (β = −0.395, p < 0.001), with a minor direct effect (β = −0.069) and two dominant indirect pathways: (1) physical activity → self-control → problematic mobile phone use (β = −0.157) and (2) physical activity → negative emotions → problematic mobile phone use (β = −0.169).
Conclusion
Findings demonstrate that physical activity reduces problematic use primarily by mitigating negative emotions (especially depression and stress) and improving self-control. Notably, these variable associations exhibit greater strength within the university student population. Interventions should integrate emotion regulation and self-control strategies to effectively address smartphone dependency and promote healthier behaviors.

Emerging evidence suggests a positive link between parental and child problematic smartphone use (PSU), yet the direction and reciprocity of this relationship over time remain unclear. Here, we address this gap by examining six years (2018–2023) of PSU data from 4,086 parent–child dyads in South Korea, comprising two cohorts: a child cohort (1,984 dyads; mean child age = 11.00, 51.1 % female; mean parent age = 42.17, 95.0 % mothers) and an adolescent cohort (2,102 dyads; mean child age = 14.00, 46.6 % female; mean parent age = 44.32, 94.6 % mothers). Random-intercept cross-lagged panel models (RI-CLPMs) revealed consistent patterns across both cohorts. At the between-dyad level, parental and child PSU covaried, such that children of parents with higher PSU also reported higher PSU. At the within-dyad level, their PSU levels co-fluctuated over time; that is, in years when parents’ PSU rose above their typical level, their children’s PSU rose as well. However, no significant cross-lagged effects emerged, indicating that increases in parental PSU did not predict subsequent changes in child PSU and vice versa. Together, these findings suggest that longitudinal co-fluctuation patterns in PSU, rather than causal transmission, exist within a shared family digital ecology, thereby highlighting family-level dynamics in understanding PSU.

Emerging adulthood, a transition period in life, is highly intertwined with uncertainty and is thus potentially associated with increased vulnerability to maladaptive coping and problematic behaviors, including problematic smartphone use (PSU). The current study was designed to test not only the associations of intolerance of uncertainty (IU) with PSU tendencies but also the underlying (meta)cognitive and affective mechanisms. A sample of 566 participants who were 18–25 years old (Mage = 20.92, SDage = 1.72; 65.3 % female) was collected. All participants completed an anonymous online questionnaire. The current results indicated a statistically significant positive association between IU and PSU tendencies. Path model further highlighted sequential mediating roles played by two components of metacognitive beliefs (i.e., negative beliefs about worry and cognitive confidence) and anxiety symptoms, underlying the IU-PSU link. Future interventions for PSU tendencies in emerging adults should consider metacognitive therapy, specifically targeting the two identified metacognitive risk factors, especially for those with IU and affective problems.

Extensive research has documented the deleterious developmental effects of problematic mobile phone use (PMPU) on emerging adults. However, in collectivistic cultures, few studies have investigated the longitudinal trend of PMPU of emerging adults and its associated environmental and individual factors. This study tracked 1,179 first-year undergraduates (67.9 % female; Mage = 18.60, SDage = 1.27) at a major Chinese university over three measurement points: baseline (upon enrollment), 3-month, and 6-month follow-ups. The findings reveal: (1) a significant linear decline in PMPU scores over time; (2) higher subjective social status is associated with lower initial PMPU levels; and (3) peer rejection positively predicted PMPU, whereas personal growth initiative showed a negative association. By mapping the developmental trajectory of PMPU and identifying key modifiable factors, this study provides a foundation for culturally tailored interventions targeting Chinese emerging adults.

Problematic mobile phone use (PMPU) has become increasingly prevalent among young adults, raising concerns about its psychological underpinnings. While shyness has been linked to PMPU, few studies have explored the symptom-level mechanisms that differentiate problematic from non-problematic users. This study employed psychological network analysis to examine the structure and central symptoms of PMPU in two groups: problematic and non-problematic mobile phone users. A total of 3227 young adults (19.21 ± 3.71 years) completed standardized measures of PMPU and shyness. Results showed that loneliness and time spent on mobile phone use formed the strongest edge in both groups. Withdrawal and mood modification were highly central in the PMPU network. Cross-symptom analysis indicated that social embarrassment and technology-mediated compensation form a self-reinforcing feedback loop in high-risk individuals. Key interactions were identified between mobile phone overuse and reduced offline social competence, inefficiency in real-world interactions, and avoidance of face-to-face communication. These findings suggest that interventions targeting emotional regulation symptoms may be particularly effective in reducing PMPU. The study also highlights the utility of psychological network analysis for identifying differential mechanisms in digital behavior patterns.

Introduction
Cannabis vape products (CVPs) have gained significant popularity as a method of cannabis consumption among U.S. young adults (YAs), raising concerns about associated health risks. This study investigates the relationship between exposure to CVP advertisements (ads) and CVP use among YAs.
Method
In 2024, we implemented a web-based survey using a purposive sample of U.S. YA participants (n = 2,204; ages 18–30) with various cannabis use behaviors. Using multivariable regression, we assessed associations between CVP ad exposure (measured by overall exposure, frequency of exposure, and number of advertising channels) and past-month CVP use and use frequency, adjusting for relevant covariates.
Results
Ad exposure (AOR = 1.41, p = 0.001; β = 0.2, p = 0.013), higher frequency of ad exposure (AOR = 1.17, p < 0.001; β = 0.10, p < 0.001), and exposure across more advertising channels (AOR = 1.08, p < 0.001; β = 0.06, p < 0.001) were significantly associated with both CVP use and CVP use frequency, respectively. Social media emerged as the most prevalent advertising channel for CVP ad exposure. Specific channels associated with CVP use included email/text messages, ads inside/outside cannabis retailers, TV/radio, ads at bars/pubs/nightclubs, social media, and websites. Similar associations were observed for CVP use frequency, except for websites.
Discussion
The study results highlight significant associations between CVP ad exposure and both CVP use and CVP use frequency among YAs, suggesting ad exposure may be a risk factor for CVP use. Further research into the content and impact of CVP advertising, particularly through digital channels like social media and email, is needed to develop strategies for reducing the appeal of such advertising to YAs.
大麻电子烟产品（cvp）作为一种大麻消费方式在美国年轻人（YAs）中非常受欢迎，引发了对相关健康风险的担忧。本研究旨在探讨青少年接触CVP广告与CVP使用的关系。方法：在2024年，我们实施了一项基于网络的调查，使用了美国YA参与者（n = 2204，年龄在18-30岁）的目的样本，他们有不同的大麻使用行为。使用多变量回归，我们评估了CVP广告曝光（通过总体曝光、曝光频率和广告渠道数量来衡量）与过去一个月CVP使用和使用频率之间的关联，并对相关协变量进行了调整。结果广告暴露（AOR = 1.41, p = 0.001; β = 0.2, p = 0.013）、较高的广告暴露频率（AOR = 1.17, p < 0.001; β = 0.10, p < 0.001）和更多广告渠道的暴露（AOR = 1.08, p < 0.001; β = 0.06, p < 0.001）分别与CVP使用和CVP使用频率显著相关。社交媒体成为CVP广告曝光最普遍的广告渠道。与CVP使用相关的具体渠道包括电子邮件/短信、大麻零售商内部/外部的广告、电视/广播、酒吧/酒吧/夜总会的广告、社交媒体和网站。除了网站之外，CVP的使用频率也有类似的关联。研究结果强调了CVP广告曝光与青少年CVP使用和使用频率之间的显著关联，表明广告曝光可能是CVP使用的一个危险因素。需要进一步研究CVP广告的内容和影响，特别是通过社交媒体和电子邮件等数字渠道，以制定降低此类广告对YAs吸引力的策略。

Background
There is a knowledge gap in the short- and long-term tobacco use patterns of adults who smoke cigarettes and initiate use of electronic cigarettes. This longitudinal study describes concurrent use transitions following e-cigarette initiation among adults who smoked cigarettes.
Methods
From December 2020-October 2021, US adults who smoked cigarettes and recently (re-)initiated e-cigarette use within the past month (N = 303) were recruited nationally for a one-year online study consisting of weekly surveys for three months followed by three quarterly surveys. At each survey, current e-cigarette use, smoking status, and frequency of use were assessed to define their concurrent use state: neither vaping nor smoking, vaping only, predominantly vaping, equal dual use, predominantly smoking, or only smoking.
Results
During the first 3 months, 74 % of participants shifted their usage states at least once, while 29 % shifted between 9 months and 12 months following e-cigarette initiation. Participants predominantly smoking initially tended to either continue predominantly smoking or returned to exclusively smoking. Those predominantly vaping tended to remain in this state or shift to only vaping. Individuals using both products split early between continued dual use, predominantly vaping, and predominantly smoking. Those only vaping tended to continue, although some reverted to smoking. Overall, initial concurrent use states appear somewhat predictive of trajectories and 12-month outcomes.
Conclusions
Additional research on predictors (e.g., demographics, product characteristics, use experiences, perceptions and affect, product availability) of these frequent shifts between concurrent use states on weekly, monthly, and quarterly basis and 12-month outcomes is needed.

Introduction
This study examines the association between cannabis use and the intersection of housing instability with sexual identity and race/ethnicity among U.S. high school students.
Methods
We utilized nationally representative survey data from high school students in 2021 and 2023 (n = 24,885), analyzed in 2024. The dependent variable was past 30-day cannabis use, and the primary independent variables were the intersection of housing instability with sexual identity and race/ethnicity. Propensity score weighting was used to balance characteristics between the intersectional variable groups, followed by logistic regression in the outcome model.
Results
Results showed significantly higher odds of cannabis use among students with housing instability who identified as heterosexual (OR = 3.38, 95 %CI = 2.69–4.23), gay or lesbian (OR = 4.71, 95 %CI = 2.55–8.68), bisexual (OR = 3.89, 95 %CI = 1.90–7.96), and other sexual identities (OR = 7.73, 95 %CI = 4.24–14.08) compared to heterosexual students with stable housing. We also found higher odds of cannabis use for those with housing instability among non-Hispanic white students (OR = 3.59, 95 %CI = 2.78–4.63), non-Hispanic black students (OR = 3.24, 95 %CI = 2.10–5.00), non-Hispanic other students (OR = 3.08, 95 %CI = 2.13–4.45), and Hispanic students (OR = 5.24, 95 %CI = 3.59–7.65) compared to non-Hispanic white students with stable housing.
Conclusions
The findings indicate a significant association between housing instability and cannabis use, particularly among sexual and racial/ethnic minorities. The intersectional analysis underscores the compounded challenges faced by these groups.
本研究探讨了美国高中生中大麻使用与住房不稳定、性别认同和种族/民族之间的关系。方法采用具有全国代表性的2021年和2023年高中生调查数据（n = 24,885），并于2024年进行分析。因变量是使用大麻超过30天，主要自变量是住房不稳定与性别认同和种族/民族的交集。倾向得分加权用于平衡交叉变量组之间的特征，然后在结果模型中进行逻辑回归。结果结果显示，与住房稳定的异性恋学生相比，异性恋（OR = 3.38, 95% CI = 2.69-4.23）、男同性恋或女同性恋（OR = 4.71, 95% CI = 2.55-8.68）、双性恋（OR = 3.89, 95% CI = 1.90-7.96）和其他性别身份（OR = 7.73, 95% CI = 4.24-14.08）的住房不稳定学生使用大麻的几率明显更高。我们还发现，与住房稳定的非西班牙裔白人学生相比，住房不稳定的非西班牙裔白人学生（OR = 3.59, 95% CI = 2.78-4.63）、非西班牙裔黑人学生（OR = 3.24, 95% CI = 2.10-5.00）、非西班牙裔其他学生（OR = 3.08, 95% CI = 2.13-4.45）和西班牙裔学生（OR = 5.24, 95% CI = 3.59 - 7.65）使用大麻的几率更高。研究结果表明，住房不稳定与大麻使用之间存在显著关联，尤其是在性别和种族/民族少数群体中。交叉分析强调了这些群体面临的复杂挑战。
