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.

Background
While sex differences in depressive symptoms and Internet Gaming Disorder (IGD) are well-documented, the existence of sex differences in their interrelations remains unclear.
Methods
This longitudinal study of 57,985 Chinese gamers (mean age: 14.12 ± 1.45 years, girls: 45.4 %) assessed sex differences in the association between IGD and depressive symptoms. We analyzed this relationship at two levels: (1) an aggregate level, using total scores from the Internet Gaming Disorder Scale-Short Form (IGDS9-SF) and the 9-item Patient Health Questionnaire (PHQ-9) via cross-lagged panel models (CLPM), and (2) a symptom level, examining individual symptoms as nodes in cross-lagged panel network analyses (CLPN). We compared cross-lagged effect strengths and identified key central symptoms (highly influential individual symptoms) and bridge symptoms (symptoms linking IGD and depression) within the IGD-depression network for boys and girls.
Results
Girls showed higher prevalence, incidence, and persistence of depression; boys had higher rates for IGD. A bidirectional association emerged between IGD and depression for both sexes. However, the strength of these reciprocal predictions (IGD ↔ depression) was significantly greater in boys. Additionally, bridge symptoms differed by sex: in boys, the bridge symptoms included Worthlessness, Psychomotor Problems, Suicidal Thoughts, and Escapism. In girls, the bridge symptoms were Suicidal Thoughts, Escapism, Concentration Difficulties, and Anhedonia.
Discussion
Significant sex differences were observed in both the epidemiology and the associations between IGD and depressive symptoms at aggregate and symptom levels. These findings underscore the necessity for sex-specific interventions to effectively address the intertwined nature of IGD and depression among adolescents.

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.

Introduction
Cannabis use among sexual minority (SM) populations, particularly through vaping (CV) and non-vaping (NVC) modes, has become increasingly relevant amid shifting legal and cultural norms. However, limited research has examined how these modalities relate to multidimensional aspects of sexual orientation. This study addresses this gap by exploring the associations between sexual identity, sexual attraction, and identity–attraction concordance or discordance with past 30-day CV and NVC among U.S. adults aged 18–64.
Methods
This study analyzed data from 2022 National Survey on Drug Use and Health (NSDUH), a nationally representative dataset (N = 40,030). Weighted multivariable logistic regression models were employed to examine the associations between cannabis use modalities and each facet of sexual orientation, adjusting for demographic variables and other substance use behaviors as covariates.
Results
Among women, bisexual identity was linked to the highest odds of CV (adjusted odds ratio [aOR] = 2.57, 95 % confidence interval [CI] = 2.00–3.30) and NVC (aOR = 2.57, 95 % CI = 2.11–3.12). Women with same-sex or both-sex attraction demonstrated higher odds of both CV and NVC, and heterosexual-discordant women were also at increased risk. Among men, however, cannabis use disparities were more consistently linked to NVC.
Conclusions
The findings underscore the multifaceted nature of sexual orientation, highlighting distinct gender-specific and modality-dependent disparities in cannabis use among SM population. Recognizing and addressing these complexities can inform culturally attuned prevention and intervention efforts that account for unique stressors within these communities, reducing substance use–related harms and advancing health equity.

Background
Patients with internet gaming disorder (IGD) suffer from an imbalance of over-integrated and weakly dissociated functional brain networks. Approach bias modification training (ApBMt) has been used to correct patients’ automatic approach biases to addictive stimuli; however, research exploring changes in brain network topology is limited.
Methods
Seventy subjects were randomly assigned to the approach-avoidance task (AAT) group or the sham-AAT group, and 57 subjects (AAT, 30; sham-AAT, 27) completed the entire procedure, which included pretests, AAT/sham-AAT interventions, and posttests. Behavioral and resting-state fMRI data were collected before and after the tests. This study aimed to investigate the effects of ApBMt on topological changes in resting functional brain networks in patients with IGD and explore the relationship between these network changes and behavioral indicators of addiction severity.
Results
Repeated-measures ANOVA of the behavioral data showed that the AAT group had significant score reductions after ApBMt. Imaging data revealed significant decreases in brain network over-integration and increases in segregation of the fronto-parietal network (FPN) and the cingulo-opercular network (CON). Additionally, a positive correlation was found between the post-pre difference in DSM-5 scores and the post-pre difference in nodal efficiency (Ne) in the anterior prefrontal cortex (aPFC).
Conclusions
The findings of this study demonstrate that ApBMt effectively reduces the severity of IGD, along with associated changes in brain network topology, such as enhanced segregation and decreased over-integration. However, it is important to highlight that the neurobiological changes observed are correlated with the reduction in IGD severity, but causality cannot be established. Further research is necessary to better understand the clinical potential of ApBMt in treating IGD, either as a stand-alone intervention or in combination with other therapeutic approaches.

Introduction
Rural- vs. urban-residing sexual minority young adults (SMYAs) display higher tobacco use rates. Less work has identified minority stressors that contribute to geographic disparities in use, particularly at the daily level.
Methods
We analyzed 2024 baseline and 14 days of daily survey data among 60 SMYAs (ages 18–34) reporting current tobacco use. Multilevel regression-based models with random intercepts and slopes examined between-person effects of rural–urban residence on daily minority stress (i.e., negative affect, positive affect, upsetting parent interactions, upsetting peer interactions, microaggressions) and daily tobacco use (aggregated across cigarettes, e-cigarettes, large cigars, little cigars/cigarillos, smokeless tobacco, nicotine pouches, hookah) and within-person effects of daily minority stress on same-day and next-day tobacco use, controlling for sociodemographics (i.e., age, sexual identity, gender identity, sex at birth, race and ethnicity).
Results
Among this sample of 60 SMYAs (Mage = 24.53 [SD = 5.19]; 50 % rural-residing; 31.7 % monosexual, 46.7 % bisexual+; 56.7 % gender minority; 55.0 % female; 47.5 % racial/ethnic minority), rural (vs. urban) residence was associated with higher levels of daily upsetting interactions with parents and higher odds of microaggressions and tobacco use. Upsetting interactions with parents and microaggressions were in turn, associated with higher odds of same-day and next-day tobacco use.
Conclusions
Minority stress experiences may impact SMYAs’ concurrent and subsequent tobacco use. These daily minority stress experiences and tobacco use episodes occur more often and at higher levels among rural- (vs. urban-) residing SMYAs, highlighting the need for interventions focused on promoting adaptive coping in response to minority stressors in real time, particularly for rural-residing SMYAs.

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.

Previous research has shown that subjective and negative solitary experiences, such as loneliness, are associated with increased problematic social media use (PSMU). However, further research is needed to examine the role of other solitary experiences and motivations for solitary behavior in PSMU. Accordingly, the current study investigated the relationships between various solitary experiences (i.e., trait loneliness, perceived isolation, lack of relational connectedness, positive solitude, and frequency of solitary behavior), motivations for solitary behavior (i.e., autonomous and controlled), motives for social media use (i.e., enhancement, coping, conformity, and social), and core and peripheral symptoms of PSMU in young adults. Eight hundred twenty-nine young adults (65 % females), aged 18 to 30 years (M = 23.76, SD = 3.16), completed self-report measures assessing the variables of interest. Psychometric network analysis was performed to estimate regularized partial correlations among variables across the entire sample. Gender differences in network properties were evaluated using the network comparison test. Results showed that controlled motivations for solitary behavior and perceived isolation were indirectly linked to core symptoms of PSMU through conformity motives. Additionally, perceived isolation was also associated with core PSMU symptoms through coping motives. No significant gender differences were found in the network properties. These findings suggest that PSMU might serve as a maladaptive strategy to temporarily compensate for involuntary solitary experiences and to seek relief from perceived isolation.

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.

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.
