The examination of the relationships among digital addiction, loneliness, shyness, and social anxiety in adolescents / El examen de las relaciones entre adicción digital, soledad, timidez y ansiedad social en adolescentes

La adicción digital, que se determina como un problema común entre los adolescentes en los últimos años, afecta negativamente la vida de los adolescentes en muchos aspectos. El objetivo del estudio es examinar las relaciones entre la adicción digital, la soledad, la timidez y la ansiedad social de los adolescentes. Gate se reunió con adolescentes que completaron la Escala de adicción digital, la versión corta de la Escala de soledad de UCLA, la Escala de timidez y la Escala de gravedad del trastorno de ansiedad social DSM-5 - Formulario infantil. Las hipótesis sugeridas se han probado utilizando los datos recopilados de 991 adolescentes y un análisis de regresión jerárquica. Los resultados de la investigación encontraron una relación positiva y significativa entre la adicción digital, la soledad, la timidez y la ansiedad social entre los adolescentes. Además, los hallazgos muestran que la adicción digital, la soledad y la timidez predicen la ansiedad social. Los resultados obtenidos demuestran que la adicción digital, la soledad y la timidez tienen efecto sobre la ansiedad social. Según los hallazgos, se sugiere aplicar diversas intervenciones educativas por parte de profesionales de la salud mental a adolescentes que presenten signos de adicción digital, soledad, timidez y ansiedad social.(AU)

Digital addiction, which is determined as a common problem among adolescents in the last years, affects the lives of adolescents nega-tively in terms of many aspects. The aim of the study is to examine the re-lationships between adolescents' digital addiction, loneliness, shyness and social anxiety. Gate gathered from adolescents who completed Digital Ad-diction Scale, Short Form of UCLA Loneliness Scale, Shyness Scale, and DSM-5 Social Anxiety Disorder Severity Scale -Child Form. The suggest-ed hypotheses have been tested using the data gathered from 991 adoles-cents and hierarchical regression analysis. The research findings found a positive and significant relationship between digital addiction, loneliness, shyness and social anxiety among adolescents. Furthermore, the findings show that digital addiction, loneliness, and shyness predict social anxiety. The results obtained prove that digital addiction, loneliness and shyness have an effect on social anxiety. According to the findings, it is suggested to applyvarious educational interventions by mental health professionals to adolescents who show signs of digital addiction, loneliness, shyness, and social anxiety.(AU)

Extensive social media use and frequency of current e-cigarette use among US youth.

Introduction: Both electronic cigarette (e-cigarette) and social media use among youth are public health concerns. While the health impacts of extensive social media use and frequent use of e-cigarettes have been discussed independently in the literature, little is known about the relationship between the two. This study aims to examine the potential association between extensive social media use and the frequency of current, e-cigarette use among United States (US) youth. Methods: Data from the 2022 National Youth Tobacco Survey (NYTS) were analyzed. The sample included 23,655 middle and high school students aged 9-18 years. Frequency of current e-cigarette use was categorized based on past-30 day use (i.e., never/former, 1-9 days, 10-29 days, or 30 days). Social media use was dichotomized into less than 4 hours daily and 4+ hours daily (i.e., extensive use). Multivariable multinomial logistic regression estimated the relationship between social media use and e-cigarette use frequency. Results: Over one-third (35.8 %) of youth used social media extensively and 8.6 % reported current use of e-cigarettes. Extensive social media use was associated with daily e-cigarette use (OR: 1.94, 95 % CI: 1.48-2.56) but not with other use categories. Older age, female sex, lower grades, current other tobacco use, and family tobacco use were also associated with daily e-cigarette use. Conclusions: Extensive social media use is associated with daily e-cigarette use among US youth. Public health interventions should consider the influence of social media on tobacco use behaviors and tailor prevention strategies to address this potential modifiable risk factor.

Prevalence and association between alcohol, tobacco, and COVID-19: a study from a tribal predominant district in eastern India.

Introduction: Alcohol and tobacco use has been proposed to significantly affect COVID-19 outcomes. The study aimed to estimate the prevalence of alcohol and tobacco use among COVID-19-positive patients and compare it with the general population prevalence rates. It also aimed to assess and determine the association between the severity of COVID-19 illness and the complications with alcohol and tobacco use. Method: For this, a cross-sectional, retrospective, telephone-based study was conducted using a structured questionnaire among COVID-19 diagnosed patients in the district of Deoghar of the Indian state of Jharkhand. A multinomial logistic regression is done to determine the association. Results: Among 1,425 patients interviewed, tobacco and alcohol were used by 22.31 and 9.96%, significantly more than the prevalence of tobacco (Z = 4.9485, p < 0.00001) and alcohol use (Z = 7.118, p < 0.00001), respectively, in the district (tobacco-11.7% and alcohol-4.8%).In a regression model, patients with co-morbidity had higher odds of severe [3.34 (1.99-5.62)] and moderate [2.95 (1.97-4.41)] COVID-19. Young [0.12 (0.04-0.38)] and middle-aged individuals [0.23 (0.13-0.4)], people below the poverty line 0.28 (0.11-0.69) are at lower odds of severe COVID-19. Tobacco users [1.58 (1.16-2.14)], alcohol users [1.53 (1.03-2.28)], incomplete vaccination [3.24 (1.49-7.01)], and patients with comorbidity [3.6 (2.79-4.68)] were found to have higher odds of post-COVID-19 complications. Discussion: People with COVID-19 in our study population had significantly higher tobacco and alcohol use compared to the general population. Tobacco and alcohol use significantly increases the risk of post-COVID-19 complications. The study highlights the need for addiction treatment services to prevent complications during future pandemics.

Exploring the association between online gaming addiction and academic performance among the school-going adolescents in Bangladesh: A cross-sectional study.

Background and Aims: The pervasive nature of online gaming, notably accentuated during the COVID-19 pandemic, has spurred concerns regarding gaming addiction among children. This study explores the intricate ramifications of online gaming addiction on the academic performance and social dynamics of children in Bangladesh. Our primary objective is to gauge the extent of online gaming addiction and unravel its profound effects on academic performance. Methods: Conducting a nationwide survey from January 1, 2023, to June 30, 2023, we analyzed 502 responses from participants aged 6-17 years. The survey encompassed sociodemographic details, gaming addiction assessment, and academic performance following a simple random sampling method. We analyzed participant demographics utilizing descriptive statistics, chi-square tests, and logistic regression. Results: Key findings revealed a majority within the 13-17 age bracket (75.50%), predominantly male (58.57%), and enrolled in secondary education (83.27%). A robust inverse relationship showed that nonaddicted students towards online gaming had higher academic performance. Therefore, it is important to implement targeted strategies to address online gaming addiction among Bangladeshi children. Conclusion: Recommending early intervention, academic initiatives, and holistic therapy, we advocate for collaboration among educational institutions, mental health professionals, parents, and policymakers. All of these initiatives are essential to navigate the evolving challenges presented by gaming addiction. Furthermore, our call for ongoing research seeks to deepen our understanding of enduring consequences on academic and social dimensions, fostering a digitally supportive environment conducive to the holistic well-being of children.

High quality, high throughput, and low-cost simultaneous video recording of 60 animals in operant chambers using PiRATeMC.

BACKGROUND: The development of Raspberry Pi-based recording devices for video analyses of drug self-administration studies has been shown to be promising in terms of affordability, customizability, and capacity to extract in-depth behavioral patterns. Yet, most video recording systems are limited to a few cameras making them incompatible with large-scale studies. NEW METHOD: We expanded the PiRATeMC (Pi-based Remote Acquisition Technology for Motion Capture) recording system by increasing its scale, modifying its code, and adding equipment to accommodate large-scale video acquisition, accompanied by data on throughput capabilities, video fidelity, synchronicity of devices, and comparisons between Raspberry Pi 3B+ and 4B models. RESULTS: Using PiRATeMC default recording parameters resulted in minimal storage (~350MB/h), high throughput (< ~120seconds/Pi), high video fidelity, and synchronicity within ~0.02seconds, affording the ability to simultaneously record 60 animals in individual self-administration chambers for various session lengths at a fraction of commercial costs. No consequential differences were found between Raspberry Pi models. COMPARISON WITH EXISTING METHOD(S): This system allows greater acquisition of video data simultaneously than other video recording systems by an order of magnitude with less storage needs and lower costs. Additionally, we report in-depth quantitative assessments of throughput, fidelity, and synchronicity, displaying real-time system capabilities. CONCLUSIONS: The system presented is able to be fully installed in a month's time by a single technician and provides a scalable, low cost, and quality-assured procedure with a high-degree of customization and synchronicity between recording devices, capable of recording a large number of subjects and timeframes with high turnover in a variety of species and settings.

Psychological Balances in the Digital World: Dynamic Relationships Among Social Media Addiction, Depression, Anxiety, Academic Self-Efficacy, General Belongingness, and Life Satisfaction.

In the present era, the rapidly growing social media trends of the digital age have the potential to affect the psychological well-being of individuals. In this context, understanding how Social Media Addiction (SMA) interacts with various factors is important to understanding its potential impact on individuals' psychosocial health. In particular, the prevalence of SMA and its strong relationship with important variables such as anxiety, depression, stress, academic self-efficacy, general belongingness, and life satisfaction have received considerable attention from researchers and the society. This research aims to address the relationship between SMA and these variables in a holistic manner. The research further explored the relationship between life satisfaction and depression, anxiety, academic self-efficacy, and general belongingness. The research is based on a study conducted with 616 students (388 female and 228 male; 17-32 age range) at a state university in the Southeast of Turkey. Personal information form, Smartphone Addiction Scale, Depression Anxiety Stress Scale, Academic Self-Efficacy Scale, General Belongingness Scale, and Life Satisfaction Scale were used as data collection tools. Using a structural equation modeling approach, the research not only examined the significant relationships but also examined the mediating and moderating effects in more detail. According to the research results, SMA significantly affects academic self-efficacy, general belongingness, depression, stress and anxiety. Academic self-efficacy and general belongingness both impact life satisfaction. However, SMA does not have a significant effect on life satisfaction. Moreover, it is revealed general belongingness play effective roles in the relationship between SMA and life satisfaction. As a result of the research, it was revealed that gender plays a moderating role in the relationship between SMA and life satisfaction. It has been observed that gender has a moderating role in the relationships between academic self-efficacy, general belongingness, depression, anxiety and stress and life satisfaction. Conversely, there is no moderating influence of gender on the impact of SMA on academic self-efficacy, general belongingness, depression, anxiety, or stress. Consequently, the relationships between SMA and other variables play an important role in understanding their effects on individuals' mental health.

The impact of anger on intertemporal decision-making in individuals with internet addiction: an fNIRS study.

Intertemporal decision-making is the choice between an immediate smaller reward (SS) and a delayed larger reward (LL). Intertemporal decision-making depends on the interaction of the cognitive and emotional systems, and the latter is particularly vital. According to the Appraisal Tendency Frame (ATF) theory, anger influences intertemporal decision-making by increasing an individual's sense of certainty and control. This study examined whether anger affects intertemporal decision-making in individuals with internet addiction (IA) in this manner and investigated its neural mechanisms. Nineteen individuals with IA and 20 healthy controls were recruited. All subjects performed the Monetary choice task under anger and neutral emotions while functional near-infrared spectroscopy (fNIRS) equipment simultaneously recorded the hemodynamics in the prefrontal cortex (PFC). Individuals with IA showed a more considerable delay discount and lower brain activations in the orbitofrontal cortex (OFC) and left dorsolateral prefrontal cortex (L-dlPFC) compared to HC. Moreover, individuals with IA made more LL choices in the angry condition than in the neutral emotion, yet there was no difference in HC. The brain activation in L-dlPFC of individuals with IA tends to increase in the angry condition compared to the neutral condition. These findings revealed that impairment of intertemporal decision-making in individuals with individuals with IA might be related to the dysfunction of OFC and L-dlPFC. Our work also provided initial footing for the applicability of the appraisal tendency frame theory to individuals with IA, and L-dlPFC might play a role in the effects of anger on intertemporal decision-making.

Racial Differences in Medications for Opioid Use Disorder Initiation in a Carceral Setting.

BACKGROUND: The opioid overdose crisis significantly affects marginalized communities, with people of color experiencing higher rates of overdose and barriers to treatment. The syndemic of opioid use disorder and mass incarceration exacerbates racial health disparities. Some carceral facilities offer medication for addiction treatment, though no significant research explores differences in type of treatment uptake by race in these settings. This study focuses on the racial differences in medications for opioid use disorder (MOUD) preferences among incarcerated individuals. METHODS: A retrospective cohort study was conducted at the Rhode Island Department of Corrections (RIDOC), examining MOUD-type preferences (buprenorphine or methadone) among incarcerated individuals. The study utilized RIDOC electronic medical records from January 1, 2017 to December 31, 2022, involving 3533 unique incarceration events. Participants were categorized by race (White vs non-White) and MOUD status (new initiation vs community continuation), with logistic regression models. RESULTS: The study found no direct racial disparity in preferences for MOUD type. However, an interaction between race and MOUD initiation status significantly influenced MOUD-type preference. Among those initiating MOUD during incarceration, non-White individuals were more likely to choose buprenorphine compared to their White counterparts. CONCLUSIONS: This research provides new insights into the intersection of race, incarceration, and MOUD preferences. While direct racial disparities in MOUD type were not observed, the analysis uncovered a notable interaction effect: race influences the relationship between MOUD initiation status and the selected MOUD treatment during incarceration. Specifically, data demonstrate that the likelihood of choosing buprenorphine varies significantly based on both racial background and whether the treatment was initiated during incarceration or in the community. Further research is needed in different geographic settings to understand the broader implications to help guide equitable healthcare delivery in jails and prisons.

Melatonin Regulates Neuronal Synaptic Plasticity in the Supramammillary Nucleus and Attenuates Methamphetamine-Induced Conditioned Place Preference and Sensitization in Mice.

Methamphetamine (METH) is an addictive drug that threatens human health. The supramammillary nucleus (SuM) and its neural circuits play key roles in the regulation of spatial memory retrieval, and hippocampal contextual or social memory. Melatonin (MLT), a pineal hormone, can regulate hypothalamic-neurohypophysial activity. Our previous study showed that MLT attenuates METH-induced locomotor sensitization. However, whether MLT regulates SuM function and participates in METH-induced contextual memory retrieval remains unclear. Using a mouse model of METH-conditioned place preference (CPP) and sensitization, we found that METH activated c-Fos expression and elevated calcium (Ca²âº) levels in SuM neurons. Chemogenetic inhibition of SuM attenuates CPP and sensitization. Pretreatment with MLT decreased c-Fos expression and Ca2+ levels in the SuM and reversed METH-induced addictive behavior, effects that were blocked with the selective MT2 receptors antagonist 4P-PDOT and the MT1 receptors antagonist S26131. Furthermore, MLT reduced SuM synaptic plasticity, glutamate (Glu) release, and neuronal oscillations caused by METH, which were blocked by 4P-PDOT. In conclusion, our data revealed that MLT regulates neuronal synaptic plasticity in the SuM, likely through the MLT receptors (MTs), and plays a role in modulating METH-addictive behavior.

Problematic overstudying, Big Five personality, and music performance anxiety: associations with well-being and GPA.

BACKGROUND: Problematic overstudying is a compulsive and pathological overinvolvement in studying leading to harm and considerable functional impairments. It is conceptualized as "study addiction," a precursor to work addiction. It has been investigated within the addictive behaviours framework in general populations of students for over a decade. A previous study analysed the problem among young musicians as a particularly vulnerable group. It found some important differences in potential personality risk factors among music academy students compared to general populations of students and showed an important role of social anxiety. The current study aimed to validate these findings in a separate larger sample and extend them by investigating the role of music performance anxiety (MPA). PARTICIPANTS AND PROCEDURE: The study was conducted among 213 students of music academies. Valid and reliable measures of study addiction, MPA, Big Five personality and well-being were used. RESULTS: The results showed that MPA played a similar role as social anxiety in terms of being a predictor, mediator, and moderator of the main replicated effects supporting the hypothesised mechanisms regulating study addiction. However, extraversion was not associated with study addiction in multiple hierarchical regression analysis, but conscientiousness and neuroticism were. Study addiction was associated with indicators of decreased well-being, above and beyond MPA, and personality. CONCLUSIONS: These results show that MPA plays an analogous role to social anxiety and that the role of Big Five personality in study addiction among young musicians requires further investigation due to inconsistent findings.

An examination of mental health policy implementation efforts and the intermediaries that support them in New Zealand, Canada and Sweden: a comparative case study.

Introduction: The implementation of evidence-informed policies and practices across systems is a complex, multifaceted endeavor, often requiring the mobilization of multiple organizations from a range of contexts. In order to facilitate this process, policy makers, innovation developers and service deliverers are increasingly calling upon intermediaries to support implementation, yet relatively little is known about precisely how they contribute to implementation. This study examines the role of intermediaries supporting the implementation of evidence-informed policies and practices in the mental health and addictions systems of New Zealand, Ontario, Canada and Sweden. Methods: Using a comparative case study methodology and taking an integrated knowledge translation approach, we drew from established explanatory frameworks and implementation theory to address three questions: (1) Why were the intermediaries established? (2) How are intermediaries structured and what strategies do they use in systems to support the implementation of policy directions? and (3) What explains the lack of use of particular strategies? Data collection included three site visits, 49 key informant interviews and document analysis. Results: In each jurisdiction, a unique set of problems (e.g., negative events involving people with mental illness), policies (e.g., feedback on effectiveness of existing policies) and political events (e.g., changes in government) were coupled by a policy entrepreneur to bring intermediaries onto the decision agenda. While intermediaries varied greatly in their structure and characteristics, both the strategies they used and the strategies they didn't use were surprisingly similar. Specifically it was notable that none of the intermediaries used strategies that directly targeted the public, nor used audit and feedback. This emerged as the principle policy puzzle. Our analysis identified five reasons for these strategies not being employed: (1) their need to build/maintain healthy relationships with policy actors; (2) their need to build/maintain healthy relationships with service delivery system actors; (3) role differentiation with other system actors; (4) perceived lack of "fit" with the role of policy intermediaries; and (5) resource limitations that preclude intensive distributed (program-level) work. Conclusion: Policy makers and implementers must consider capacity to support implementation, and our study identifies how intermediaries can be developed and harnessed to support the implementation process.

The Bidirectional Association between Internet Use, Sleep Quality and Eating Behavior: A Cross-Sectional Study in Northwestern Thrace Region in Türkiye.

OBJECTIVE: This study aimed to examine the complex associations between Internet addiction, sleep disturbances, and disordered eating behaviors. METHODS: This cross-sectional study included 646 students from 17 high schools in Edirne, Türkiye between December 2023 and May 2024. A face-to-face questionnaire was administered to assess demographic characteristics, Internet addiction (YIAT), sleep quality (PSQI), and eating behavior (TFEQ-R21). RESULTS: In total, 644 students completed the study. The prevalence of Internet addiction among adolescents was 16.3%, with a similar prevalence among male and female adolescents. The prevalence of poor sleep quality among adolescents was 6.4%, and this trend was more pronounced in male adolescents, with an incidence of 13.0%. A weak positive correlation was observed between Internet addiction and disordered eating behavior. Additionally, a moderate positive correlation was observed between poor sleep quality and disordered eating behavior. Gender, maternal education level, Internet addiction, and poor sleep quality were significant predictors of eating disorders in adolescents. CONCLUSION: The findings of our study are of significant value in providing insights into the development of programs designed to prevent undesired eating behaviors.

Effects of interventions to combat tobacco addiction: Cochrane update of 2021 to 2023 reviews.

AIMS: To summarise systematic reviews on tobacco addiction published by the Cochrane Tobacco Addiction Group (CTAG) from 2021 to 2023. METHODS: We identified all new and updated Cochrane Reviews published by CTAG between 2021 and 2023. We present key results from these reviews and discuss promising avenues for future research. RESULTS: CTAG published five new reviews and one overview of reviews, and updated eight reviews. Review evidence showed that all main pharmacotherapies (varenicline, cytisine, bupropion and nicotine replacement therapy [NRT], especially when patches are combined with fast acting forms like gum) are effective for smoking cessation, as are nicotine e-cigarettes. Evidence suggested similar magnitude of effects of varenicline, cytisine, and nicotine e-cigarettes; these emerged as the most effective treatments. Evidence also supported behavioural counselling and financial incentives for smoking cessation. Secondary analyses of the Cochrane review of e-cigarettes for smoking cessation showed over half of participants assigned to e-cigarette conditions were still using them at six months or longer, that biomarkers of potential harm significantly reduced in people switching from smoking to vaping or to dual use, and that there was insufficient evidence to draw associations between e-liquid flavours and smoking cessation. Findings on mindfulness-based interventions, interventions delivered by dental and primary care professionals, interventions to prevent weight gain after smoking cessation, and interventions for waterpipe cessation were less certain. Reviews of observational evidence showed that smoking cessation reduced cardiovascular events and mortality in people living with cardiovascular disease, and improved mental health. CONCLUSIONS: Nicotine replacement therapy (especially patches combined with fast acting forms), varenicline, cytisine, bupropion, nicotine e-cigarettes, behavioural counselling, and financial incentives are all effective ways to help people quit smoking. Quitting smoking improves mental health and reduces cardiovascular events and mortality in people living with cardiovascular disease.

Lack of Parental Control Is Longitudinally Associated With Higher Smartphone Addiction Tendency in Young Children: A Population-Based Cohort Study.

The purpose of the current study was to examine the risk factors of young children's smartphone addiction in a longitudinal study design. Data collected from 313 participants (mean age, 4.5 ± 0.82 years; male, 49.8%) over 4 years for Kids Cohort for Understanding of Internet Addiction Risk Factors in Early Childhood were analyzed in this study. Mixed effect models were used to evaluate the influence of various variables on the repeated measures of smartphone addiction tendency in young children over time. The multi-level analysis showed that parents' lack of control over children's smartphone use (t = -4.523; 95% confidence interval [CI], -7.32, -1.72), and parents' higher smartphone addiction proneness (t = 6.340; 95% CI, 0.23, 0.440) predicted higher smartphone addiction tendency in young children. The responsibility of the parents to prevent their children from becoming addicted to smartphones should start in a very early age when they start using the smartphones.

Within-session chasing of losses and wins in an online eCasino.

Chasing refers to the escalation of betting behaviour. It is conventionally seen when losing but can also be seen after wins. Diagnostic and screening items for gambling problems describe chasing as returning 'another day' to gamble. However, gamblers may also chase within sessions, and this is particularly relevant in online gambling. This study focused on two expressions of within-session chasing: (1) increasing the bet amount, or (2) a reduced probability of quitting the session, as a function of prior losses or wins. These expressions were examined across five online gambling products: slot machines, probability games, blackjack, video poker, and roulette. Our results showed that gamblers bet more and played longer sessions after immediate losses, but they bet less and played shorter sessions when losing cumulatively. The reversed pattern in the cumulative model may be due to financial constraints. For wins, gamblers bet more after both immediate and cumulative wins, but they also played shorter sessions. Chasing patterns were qualitatively similar by game type-with limited evidence for our hypothesis that chasing would be greatest for slot machines as an established high-risk category. Overall, chasing is multi-faceted, varying across the behavioural expressions, by the immediate or cumulative timeframe of prior outcomes, and by game type.

The role of pituitary adenylate cyclase-activating polypeptide neurons in the hypothalamic ventromedial nucleus and the cognate PAC1 receptor in the regulation of hedonic feeding.

Obesity is a health malady that affects mental, physical, and social health. Pathology includes chronic imbalance between energy intake and expenditure, likely facilitated by dysregulation of the mesolimbic dopamine (DA) pathway. We explored the role of pituitary adenylate cyclase-activating polypeptide (PACAP) neurons in the hypothalamic ventromedial nucleus (VMN) and the PACAP-selective (PAC1) receptor in regulating hedonic feeding. We hypothesized that VMN PACAP neurons would inhibit reward-encoding mesolimbic (A10) dopamine neurons via PAC1 receptor activation and thereby suppress impulsive consumption brought on by intermittent exposure to highly palatable food. Visualized whole-cell patch clamp recordings coupled with in vivo behavioral experiments were utilized in wildtype, PACAP-cre, TH-cre, and TH-cre/PAC1 receptor-floxed mice. We found that bath application of PACAP directly inhibited preidentified A10 dopamine neurons in the ventral tegmental area (VTA) from TH-cre mice. This inhibitory action was abrogated by the selective knockdown of the PAC1 receptor in A10 dopamine neurons. PACAP delivered directly into the VTA decreases binge feeding accompanied by reduced meal size and duration in TH-cre mice. These effects are negated by PAC1 receptor knockdown in A10 dopamine neurons. Additionally, apoptotic ablation of VMN PACAP neurons increased binge consumption in both lean and obese, male and female PACAP-cre mice relative to wildtype controls. These findings demonstrate that VMN PACAP neurons blunt impulsive, binge feeding behavior by activating PAC1 receptors to inhibit A10 dopamine neurons. As such, they impart impactful insight into potential treatment strategies for conditions such as obesity and food addiction.

Association Between Internet Addiction and Dietary Habits Among Omani Junior College Students.

Objectives: This study aimed to investigate the association between internet addiction and dietary habits among Omani junior college students. Methods: This cross-sectional study was conducted at Sultan Qaboos University, Muscat, Oman, among junior college students surveyed in November 2020. The Compulsive Internet Use Scale and a dietary habits questionnaire were used. Chi-square cross-tabulation analyses were used to explore the relationship between internet addiction and dietary habits. Results: A total of 377 students were included in this study. Overall, 59.9% of the junior college students were identified as having an internet addiction. Within this group, 62.8% reported reduced meal sizes and 54.4% reported a decrease in appetite. There was a statistically significant difference in both meal size (X2 = 30.528; P <0.001) and appetite changes (X2 = 28.731; P <0.001) among students with different levels of internet addiction. Conclusion: The results of this study suggest a possible link between internet addiction and altered dietary habits among this population. This study highlights the need for strategies that encourage healthy living behaviours and raise awareness about the adverse effects of internet addiction.

Knowledge of medications for opioid use disorder and associated stigma among primary care professionals.

BACKGROUND: Medications for opioid use disorder (MOUD) are the gold standard. However, significant barriers limit their use in the primary care setting, including limited knowledge of the medications and stigmatizing attitudes. In this study, we assess knowledge levels among primary care-aligned professionals (PCPs) currently in practice, and whether knowledge of MOUD is associated with stigma and treatment attitudes. PARTICIPANTS AND METHODS: Using rosters from the state of Ohio licensing boards, we surveyed 403 physicians, nurse practitioners, and physician associates in 2022, on the mechanism of different MOUD, as well as stigma and treatment attitudes. To assess MOUD knowledge, we employed descriptive and bivariate statistics. We fit four linear regression models, which controlled for empathy towards patients with OUD and provider demographics to assess the relationship between MOUD knowledge and four endpoints: stigma, perceived controllability of opioid use, perceived vulnerability to opioid use disorder, and support for abstinence-only treatment. RESULTS: 43% of participants correctly identified the mechanism of all 3 medications whereas 13% of participants did not identify the mechanism of any MOUD correctly. MOUD knowledge was higher among physicians as compared to nurse practitioners and physician associates. Lower MOUD knowledge was associated with more negative attitudes towards patients with OUD and MOUD treatment. CONCLUSION: Expanding access to MOUD treatment requires a trained and willing health-care professional (HCP) workforce. Our findings highlight considerable variation in clinician knowledge of MOUD and suggest that knowledge levels are also related to negative attitudes towards patients with OUD and MOUD. Training interventions that increase knowledge, as well as focus on stigma reduction, are critical for reducing the longstanding treatment gap for opioid use disorder.

A comprehensive evaluation of the neurocognitive predictors of problematic alcohol use, eating, pornography, and internet use: A 6-month longitudinal study.

Background and aims: Cognitive control and reward-related abnormalities are centrally implicated in addiction. However, findings from longitudinal studies addressing neurocognitive predictors of addictive behaviors are mixed. Further, little work has been conducted predicting non-substance-related addictive behaviors. Our study aimed to assess predictors of substance and non-substance addictive behaviors in a community sample, systematically evaluating each neurocognitive function's independent influence on addictive behavior. Methods: Australians (N = 294; 51.7% female; M[SD] age = 24.8[4.7] years) completed online neurocognitive tasks and surveys at baseline and 3-month follow-up. Self-report scales assessed problematic alcohol use, addictive eating (AE), problematic pornography use (PPU), and problematic internet use (PUI) at 3- and 6-month follow-ups. Linear regressions with bootstrapping assessed neurocognitive predictors for each addictive behavior across a 6-month period. Results: Neurocognition at baseline did not predict AE or PUI severity at 6-month follow-up. Less delay discounting at baseline predicted higher PPU at 6-month follow-up (ß = -0.16, p = 0.005). Poorer performance monitoring at baseline predicted higher AE at 3-month follow-up (ß = -0.16, p = 0.004), and more reward-related attentional capture at 3-months predicted higher AE at 6-month follow-up (ß = 0.14, p = 0.033). Less reward-related attentional capture (ß = -0.14, p = 0.003) and less risk-taking under ambiguity (ß = -0.11, p = 0.029) at baseline predicted higher PUI at 3-month follow-up. All findings were of small effect size. None of the neurocognitive variables predicted problematic alcohol use. Discussion and conclusions: We were unable to identify a core set of specific neurocognitive functions that reliably predict multiple addictive behavior types. However, our findings indicate both cognitive control and reward-related functions predict non-substance addictive behaviors in different ways. Findings suggest that there may be partially distinct neurocognitive mechanisms contributing to addiction depending on the specific addictive behavior.

A familial subtype of gambling disorder.

Background: Although family history of psychiatric disorders has often been considered potentially useful in understanding clinical presentations in patients, it is less clear what a positive gambling family history means for people with gambling disorder. We sought to understand the clinical impact of having a first-degree relative with gambling disorder in a sample of adults with gambling disorder. Methods: Data from 455 participants (aged 18-65 years) who had participated in previous pharmacological and psychotherapeutic clinical trials for gambling disorder were pooled in a secondary analysis. Demographic and clinical variables were compared between those who did versus did not have one or more first-degree relative(s) with gambling disorder. Additionally, we examined whether a family history of gambling disorder was associated with treatment outcome. Results: 223 (49.0%) participants had at least one first-degree family member(s) with gambling disorder. In terms of clinical variables, family history of gambling disorder was significantly associated with being female, having an earlier age of gambling onset, longer duration of untreated gambling illness, a greater likelihood of developing legal problems secondary to gambling, and higher rates of alcohol use disorder in family members. Family history of gambling disorder was also associated with a greater gambling symptom improvement from pharmacotherapy. Conclusions: These results indicate that gamblers with a first-degree family member with a gambling disorder may have a unique clinical presentation and better response to treatment interventions.
