Detection and Characterization of Online Substance Use Discussions Among Gamers: Qualitative Retrospective Analysis of Reddit r/StopGaming Data.

BACKGROUND: Video games have rapidly become mainstream in recent decades, with over half of the US population involved in some form of digital gaming. However, concerns regarding the potential harms of excessive, disordered gaming have also risen. Internet gaming disorder (IGD) has been proposed as a tentative psychiatric disorder that requires further study by the American Psychological Association (APA) and is recognized as a behavioral addiction by the World Health Organization. Substance use among gamers has also become a concern, with caffeinated or energy drinks and prescription stimulants commonly used for performance enhancement. OBJECTIVE: This study aimed to identify substance use patterns and health-related concerns among gamers among a population of Reddit users. METHODS: We used the public streaming Reddit application programming interface to collect and analyze all posts from the popular subreddit, r/StopGaming. From this corpus of posts, we filtered the dataset for keywords associated with common substances that may be used to enhance gaming performance. We then applied an inductive coding approach to characterize substance use behaviors, gaming genres, and physical and mental health concerns. Potential disordered gaming behavior was also identified using the tentative IGD guidelines proposed by the APA. A chi-square test of independence was used to assess the association between gaming disorder and substance use characteristics, and multivariable logistic regression was used to analyze whether mental health discussion or the mention of any substance with sufficient sample size was significantly associated with IGD. RESULTS: In total, 10,551 posts were collected from Reddit from June 2017 to December 2022. After filtering the dataset for substance-related keywords, 1057 were included for further analysis, of which 286 mentioned both gaming and the use of ≥1 substances. Among the 286 posts that discussed both gaming and substance use, the most mentioned substances were alcohol (n=132), cannabis (n=104), and nicotine (n=48), while the most mentioned genres were role-playing games (n=120), shooters (n=90), and multiplayer online battle arenas (n=43). Self-reported behavior that aligned with the tentative guidelines for IGD was identified in 66.8% (191/286) posts. More than half, 62.9% (180/286) of the posts, discussed a health issue, with the majority (n=144) cited mental health concerns. Common mental health concerns discussed were depression and anxiety. There was a significant association between IGD and substance use (P<.001; chi-square test), and there were significantly increased odds of IGD among those who self-reported substance use (odds ratio 2.29, P<.001) and those who discussed mental health (odds ratio 1.64, P<.03). CONCLUSIONS: As gaming increasingly becomes highly prevalent among various age groups and demographics, a better understanding of the interplay and convergence among disordered gaming, substance use, and negative health impacts can inform the development of interventions to mitigate risks and promote healthier gaming habits.

Cannabis cue-reactivity in cannabis use disorder: Diverging evidence in two distinct cannabis cultures.

BACKGROUND: Cannabis policies and attitudes play a role in the development and presentation of cannabis use disorder (CUD), but it is unclear how these factors are related to biomarkers of addiction. The current study examined cross-cultural differences in cannabis attitudes, cannabis cue-reactivity in the brain and its associations with cannabis use measures and cannabis attitudes. DESIGN: Cross-sectional fMRI study. SETTING: The Netherlands (NL) and Texas (TX), USA. PARTICIPANTS: 104 cannabis users with CUD (44% female; NL-CUD = 54, TX-CUD = 50) and 83 non-using controls (52% female; NL-CON = 50, TX-CON = 33). MEASUREMENTS: Self-reported positive (perceived benefits) and negative (perceived harms) cannabis attitudes and tactile cannabis cue-reactivity assessed using a 3T MRI scanner. FINDINGS: While the CUD group overall was more positive and less negative about cannabis and reported higher craving, the TX-CUD group reported significantly more positive and less negative attitudes and less craving than the NL-CUD group. Cannabis cue-reactivity was observed in the CUD group in clusters including the precuneus, lateral occipital cortex, frontal medial cortex, nucleus accumbens, and thalamus. In the TX-CUD group, a positive association was observed between symptom severity and cue-induced craving and cannabis cue-reactivity in precuneus and occipital cortex clusters, while a negative association was observed in the NL-CUD group. In these clusters, individuals with more positive attitudes exhibited a positive association between craving and cue-reactivity and those with less positive attitudes exhibited a negative association. No associations with quantity of use were observed. CONCLUSIONS: Cue-induced craving might be deferentially associated with cannabis cue-reactivity across distinct cannabis use environments.

Reduced brain connectivity underlying value-based choices and outcomes in stimulant use disorder.

BACKGROUND: Patients with stimulant use disorder (SUD) show impairments when making value-based choices that are associated with disruptions in neural processing across brain networks. Making optimal choices requires learning from outcomes to update knowledge and further optimise ongoing behaviour. The optimal functioning of neural systems that underpin the ability to make favourable choices is an essential component for life functioning, and successful recovery in patients with SUD. Therefore, we sought to investigate the neural processes that underpin value-based choices in SUD patients. We hypothesise that patients with SUD have reduced functional connectivity while making financial choices during a probabilistic reinforcement learning task. METHODS: We investigated connectivity associated with loss and reward value-based choices and their outcomes in patients with SUD and healthy control participants during a pharmacological magnetic resonance imaging study. Participants received a single dose of a dopamine receptor agonist, pramipexole, and a dopamine receptor antagonist, amisulpride, in a randomised, double-blind, placebo-controlled, balanced, crossover design. Functional task-related connectivity was analysed taking a whole brain connectomics approach to identify networks that are differentially modulated by dopaminergic receptor functioning. RESULTS: SUD patients showed widespread reductions in connectivity during both reward and loss value-based choices and outcomes, which were negatively correlated with the duration of stimulant drug use. Disturbances to functional brain connectivity in SUD patients during task performance were not modulated acutely by either amisulpride or pramipexole. CONCLUSIONS: Reductions in brain connectivity, particularly when making value-based choices and processing outcomes, may underlie learning impairments in SUD patients. Given that acute dopaminergic modulation did not improve brain connectivity impairments in SUD patients, it is likely that alternative treatments are needed.

Combined Addiction and Neurobiological Targets: An In Silico Analysis of Areca Nut and Areca Nut with Tobacco Biomolecules.

BACKGROUND: The addictive potential of areca nut (AN) and tobacco is well-documented, but their combined neurobiological effects in AN-containing tobacco products (ANTP) remain obscure. This study employed a three-stage in silico approach to investigate the potential targets and pathways associated with the addictive properties of AN alone and in ANTP. MATERIALS AND METHODS: Bioactive molecules were retrieved for AN and tobacco, followed by target prediction and pathway enrichment analysis. The identified biomolecules were categorized into AN and ANTP groups. RESULTS: A total of 195 bioactive molecules were identifid (38 to AN, 157 to tobacco). Absorption, distribution, metabolism, and excretion (ADME) details were retrieved. Predicted bioactivity (gene/protein interaction probability ≥80%) was analysed, revealing 13 shared targets between AN and tobacco, 12 exclusive to AN, and 33 exclusive to tobacco. AN and ANTP influenced 21 and 27 pathways (FDR ≤ 0.05), respectively, with distinct footprints. Notably, GABAergic and cholinergic synapses, nicotine addiction, calcium signaling, and morphine addiction pathways were differentially enriched between AN and ANTP. DISCUSSION: This study highlights the distinct and synergistic neurobiological effects of AN and tobacco in ANTP. The identified differences in target genes and pathways underscore the need for tailored interventions and cessation strategies for users of AN and ANTP products. Further research is warranted to validate these findings, explore interplay between diverse addiction factors, and develop effective prevention and treatment programs.

Videoconference-Delivered Cognitive Behavioral Therapy for Parents of Adolescents With Internet Addiction: Pilot Randomized Controlled Trial.

BACKGROUND: The rise in internet addiction, including web-based gaming and social networking services, is a serious concern. Even with access to medical institutions and counseling services, individuals with internet addiction, particularly adolescents, often refuse medical treatment or counseling. Parent-focused psychological intervention may lead to positive outcomes by improving the parent-adolescent relationship and helping parents identify and modify their adolescent's problematic behaviors, including internet addiction. OBJECTIVE: This study was a pilot randomized controlled trial to test the feasibility of remote cognitive behavioral therapy via videoconferencing for parents of adolescents with internet addiction. METHODS: A total of 13 parents of adolescents aged 12-20 years with internet addiction were recruited and randomly assigned to either 12 sessions of the videoconference-delivered cognitive behavioral therapy (vCBT) group (n=6, 46%) or the waitlist control group (n=7, 54%). The study period was from March 1, 2018, to March 31, 2022. The primary outcome was the scores of the Young Internet Addiction Test reported by the adolescents. The secondary outcomes were adolescents' hours of internet use per day (Internet Addiction Test), reported by the adolescents and by their parents; the Young Diagnostic Questionnaire, completed by the parents; and the quality of life of the adolescents and the parents, measured by the EQ-5D-5L. These were evaluated at weeks 0 and 13. RESULTS: As the primary outcome, the mean total Internet Addiction Test score decreased from 67.7 (SD 18.3; 6/13, 46%) at week 0 to 56.2 (SD 25.1; 5/9, 56%) at week 13 in the vCBT group, compared to an increase from 66.9 (SD 21.9; 7/13, 54%) to 68.0 (SD 18.7; 4/9, 44%) in the control group. For all outcomes, no significant differences were found between the 2 groups (all P>.05). CONCLUSIONS: This study suggested the practical feasibility of vCBT for parents of adolescents with internet addiction. Further large-scale, multicenter randomized controlled trials are necessary to examine the effectiveness.

Internalized weight stigma and psychological distress mediate the association of perceived weight stigma with food addiction among young adults: A cross-sectional study.

BACKGROUND: Perceived weight stigma (PWS) and internalized weight stigma (IWS) are both associated with psychological distress and food addiction (FA). Using the previously proposed 'cyclic obesity/weight-based stigma' (COBWEBS) model, the present study extended the framework to investigate the mediating effects of IWS and psychological distress in the association between PWS and FA among young adults. Given that individuals who are overweight/have obesity have different vulnerabilities, this population was separately analyzed alongside the total study population. METHODS: An online survey comprising the Perceived Weight Stigma Scale, Weight Bias Internalization Scale (WBIS), Depression, Anxiety and Stress Scale-21 (DASS-21), and modified Yale Food Addiction Scale Version 2 was completed by 601 participants (59.6% females; mean age 29.3 years [SD = 6.07]). A total of 219 participants were categorized as being overweight/having obesity. RESULTS: A direct correlation was found between PWS and FA (standardized coefficient [ß] = 0.28, p < 0.001) among both populations, and was mediated by IWS and psychological distress (ß [95% CI] = 0.03 [0.01, 0.05] for WBIS score and 0.10 [0.06, 0.14] for DASS-21 score) among the total participants, but only mediated by psychological distress among participants who were overweight/had obesity (ß [95% CI] = 0.14 [0.06, 0.24]). CONCLUSIONS: The results demonstrated novel perspectives by showing the direct association between PWS and FA and the mediating roles of IWS and psychological distress. Treatment strategies such as psychological acceptance and psychoeducation could be used to reduce weight stigma, which could have positive downstream benefits of ameliorating FA. Future research may seek to study strategies for reducing weight stigma and psychological distress, to investigate their efficacy in improving disordered eating.

Social media addiction and personality dimensions among Tunisian medical students.

Purpose: Social media (SM) has become a common activity for today's young people. It is sometimes overused and potentially results in SM addiction. This study aims to assess SM addiction and its associated factors in medical students and to examine its relationship with dimensions of personality global self-esteem, and social self-esteem. Materials and methods: We carried out a cross-sectional study among a sample of medical students in the region of Sfax in Tunisia. Social Media Addiction Scale-Student Form (SMAS-SF), Big Five Inventory, Rosenberg Self-Esteem Scale, and Social Self-Esteem Inventory were used to collect data. Results: Overall, 116 medical students were included in the survey. The median age of the participants was 26 years, and 91 students (78.4%) were female. Almost half of them (55.20%) were enrolled in the third cycle. The most widely used SM was Facebook (98.3%). Students with the highest SMAS-SF scores had a significantly younger age of first use (p=0.011, r=-0.235), spent more time on their favorite SM (p=0.005, r=0.260), and performed more activities on SM, namely: making comments (p=0.005), browsing SM profiles (p=0.018), and posting videos (p=0.007) or pictures (p=0.002). The need to establish an identity was significantly associated with higher SMAS-SF scores (p=0.011). We also found that neuroticism and a low level of conscientiousness were linked to high SMAS-SF scores (p=0.006, r=0.252 and p=0.050, r=-0.183, respectively). Moreover, high SMAS-SF scores were significantly related to lower global and social self-esteem scores (p=0.015, r=-0.226 and p=0.032, r=-0.199, respectively). Conclusion: Our results highlight the critical need to take into consideration the evaluation and intervention of self-esteem and personality dimensional issues to target interventions for SM addiction among medical students.

Understanding e-Cigarette Addictiveness: Triangulation of Focus Group and Netnographic Data.

BACKGROUND: Numerous studies have shown that e-cigarettes are addictive. For example, we previously showed that users of e-cigarette online forums discuss experiences of addiction in a netnographic analysis. However, it is unclear what makes e-cigarettes addictive apart from nicotine. In a focus group analysis, we recently identified 3 unique features of e-cigarettes that users linked to experiences of addiction: the pleasant taste, unobtrusiveness, and unlimited usability of e-cigarettes. OBJECTIVE: This study aimed to validate the previously identified features of e-cigarette addictive potential by triangulating data from the netnographic analysis and focus group discussions. METHODS: Drawing on a netnographic analysis of 3 popular, German-language e-cigarette forums, we studied whether experiences of addiction were linked to specific e-cigarette features. We included 451 threads in the analysis that had been coded for addictive experiences in a previous study by our team. First, we conducted a deductive analysis with preregistered codes to determine whether the features of pleasant taste, unobtrusiveness, and unlimited usability were mentioned in relation to the addictive potential of e-cigarettes in the online forums. Second, an inductive approach was chosen to identify further possible addictive features of e-cigarettes. RESULTS: Our deductive analysis confirmed that the features highlighted in our previous focus group study (pleasant taste, unobtrusiveness, and unlimited usability) were also frequently discussed in online forums in connection to addictive symptoms. In addition, our inductive analysis identified nicotine dosage as a significant feature linked to addiction. Users reported varying their nicotine doses for different reasons, leading to the identification of four distinct user types based on dosing patterns: (1) high doses for intermittent, (2) high doses for constant use, (3) low doses for constant use, and (4) switching between high and low doses depending on the situation. CONCLUSIONS: Our comprehensive analysis of online forum threads revealed that users' experiences of addiction are linked to 4 specific features unique to e-cigarettes: pleasant taste, unobtrusiveness, unlimited usability, and nicotine dosage. Recognizing these addictive features of e-cigarettes is crucial for designing cessation programs and informing public health policies to reduce the addictiveness of e-cigarettes.

Choice of alcohol over a natural reward: an experimental study in light and heavy social drinkers.

RATIONALE & OBJECTIVES: A core symptom of alcohol use disorder (AUD) is a progressively increased choice of alcohol over alternative rewards despite negative consequences. Here, we investigated choice between personalized alcohol vs. natural rewards in a laboratory setting, and compared this behavior between non-treatment-seeking heavy drinkers and light social drinkers. METHODS: 30 light social drinkers (15 men drinking < 15 drinks/week and 15 women drinking < 10 drinks/week) and 30 heavy, non-treatment-seeking drinkers (drinking more than these levels; 15 women). In the Concurrent Choice Alcohol Food (CCAF) task, participants chose between individually tailored images of alcohol and snack rewards and collected points towards the respective reward. To assess cost sensitivity, points associated to the images varied so that they favored alcohol or snack, or were equal, creating three relative point levels. RESULTS: Choice preference for alcohol was strongly correlated with Alcohol Use Disorder Identification Test (AUDIT) scores, supporting the external validity of the choice procedure. Compared to light drinkers, heavy drinkers showed increased choice preference for alcohol, as indicated by a between-group difference in points of subjective equality, a metric that quantifies the relative point level at which alcohol and snacks were equally likely to be chosen. In both groups, choice preference strongly depended on the relative point level of alcohol compared to snacks, suggesting that responding for alcohol in heavy drinkers was sensitive to costs. CONCLUSIONS: Our results replicate previous findings of a relationship between self-reported alcohol use and choice preference for alcohol. We also found that choice behavior was strongly dependent on relative cost of alcohol in both groups, although price sensitivity was lower in heavy compared to light drinkers. An increased choice preference for alcohol in heavy drinkers suggests that they attribute a higher relative reinforcing value to alcohol compared to natural rewards.

Punitive state policies targeting alcohol use during pregnancy and alcohol consumption among pregnant women.

This study aimed to determine whether punitive state alcohol policies targeting pregnant women who drink alcohol are associated with decreased alcohol consumption among pregnant women over time. This study used data from the Pregnancy Risk Assessment Monitoring System (15 states) between 1990 and 2015. A difference-in-difference (DiD) approach was employed to determine whether passage of state laws changed alcohol consumption rates among pregnant women, while controlling for state and time fixed effects. The study specifically examined punitive state alcohol policies that clarify the admissibility of evidence in child welfare proceedings related to prenatal alcohol exposure, focusing on allegations of child abuse, child neglect, child deprivation, or child dependence, as well as proceedings seeking termination of parental rights. Punitive state alcohol policies were not significantly associated with decreased rates of alcohol consumption among pregnant women (+ 1.54%, 95% CI, -1.47-4.55), within 3 years of implementation. State alcohol policies that adopted a punitive stance toward pregnant women who drink alcohol did not result in the reduction of drinking during pregnancy. Given that punitive policies may not effectively reduce alcohol consumption during pregnancy, our findings highlight the need for reevaluation and potential reform to better address maternal/child health outcomes.

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.

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.

Rationalising a spectrum of problematic exercise: A qualitative study.

Whilst a substantial body of evidence supports the benefits of exercise for physical and mental health, the overfocus on the benefits of exercise could result in harmful behaviours in some individuals. Conceptualised as a behavioural addiction, research often dichotomises the behaviour through a medical diagnostic model. The present qualitative study explored the meaning of problematic behaviour from the exerciser's perspective. Nineteen UK-based frequent exercisers were interviewed regarding their experiences. Thematic analysis described three themes: 'relentlessly pushing the limits' of their personal best and comparing to others; 'an enabling community' which could promote problematic behaviours; and 'the complexity of the ideal body' focussing on perceptions of weight maintenance. Transcending these themes was the notion of 'rationalising choices'. The results indicate that participants felt that the benefits outweighed the costs, encouraging them to continue, even when causing harm. These findings support the notion of problematic exercise as a continuum, rather than dichotomous.

The influence of age on gambling problems worldwide: A systematic review and meta-analysis of risk among younger, middle-aged, and older adults.

Background and Aims: Problem gambling (PG) represents a significant public health concern with widespread effects in various cultures and regions globally, with younger individuals and males at a particularly higher risk. This disparity is attributed to a mix of cultural, developmental, and biological influences. To date, there has not been a comprehensive examination to determine whether this risk pattern holds consistently across different jurisdictions. Methods: We performed a systematic review and meta-analysis using the PRISMA framework, identifying 21 eligible studies from 18 countries, encompassing 156,249 participants (47.6% male and 52.4% female). Results: The studies varied considerably by region (Asia: 19%, Europe: 52%, Oceania: 19%, North America: 10%), the diagnostic criteria for PG, and participation rates in gambling (ranging from 12% to 92%). Data on PG prevalence was categorised by gender and three age groups (young: 18-35, middle: 30-55, and older: 45-65). Using a random-effects meta-analysis, we found a global PG prevalence of 1.9%. Europe reported a significantly lower prevalence (1.3%) compared to North America (5.3%). Men were found to be 3.4 times more likely than women to engage in problem gambling, although the gap narrows in North America. The young demographic showed a 1.51 times higher likelihood of reporting PG compared to the middle-aged group, whereas older adults were 0.80 times less likely to report PG. Notably, age-related effects varied significantly across regions. Conclusions: Our findings confirm that age and gender significantly influence PG risk across cultures, with significant heterogeneity observed across jurisdictions.

A brainstem circuit amplifies aversion.

Dynamic gain control of aversive signals enables adaptive behavioral responses. Although the role of amygdalar circuits in aversive processing is well established, the neural pathway for amplifying aversion remains elusive. Here, we show that the brainstem circuit linking the interpeduncular nucleus (IPN) with the nucleus incertus (NI) amplifies aversion and promotes avoidant behaviors. IPN GABA neurons are activated by aversive stimuli and their predicting cues, with their response intensity closely tracking aversive values. Activating these neurons does not trigger aversive behavior on its own but rather amplifies responses to aversive stimuli, whereas their ablation or inhibition suppresses such responses. Detailed circuit dissection revealed anatomically distinct subgroups within the IPN GABA neuron population, highlighting the NI-projecting subgroup as the modulator of aversiveness related to fear and opioid withdrawal. These findings unveil the IPN-NI circuit as an aversion amplifier and suggest potential targets for interventions against affective disorders and opioid relapse.

Associations between smartphone addiction, parenting styles, and mental well-being among adolescents aged 15-19 years in Gujarat, India.

BACKGROUND: The pervasive use of smartphones among adolescents has raised concerns about addiction and its impact on mental well-being. This study investigates the prevalence of smartphone addiction and its associations with socio-demographic factors, parenting styles, and mental health among Indian adolescents. METHODS: A cross-sectional study was conducted among 560 school-going adolescents (aged 15-19) in Gujarat, India, from January to October 2023. Data was collected using validated scales: the Smartphone Addiction Scale-Short Version (SAS-SV), the Parenting Styles and Dimensions Questionnaire (PSDQ), and the Depression Anxiety Stress Scale-21 (DASS-21). Bivariate and multivariate logistic regression analyses were performed to identify factors associated with smartphone addiction. RESULTS: The prevalence of smartphone addiction was 64.6%. Urban residence (AOR: 2.4, 95% CI: 1.8-3.3), higher parental education (AOR: 3.3, 95% CI: 1.7-4.3 for graduate fathers), longer smartphone use (AOR: 2.08, 95% CI: 1.7-3.6 for > 3 years), and higher socioeconomic status (AOR: 1.9, 95% CI: 1.5-3.51) were associated with increased odds of addiction. Authoritarian and permissive parenting styles in both parents were positively associated with smartphone addiction, while authoritative parenting was negatively associated. Smartphone addiction was strongly associated with mental health issues, particularly with severe stress (AOR: 10.82, 95% CI: 5.11-22.88, p < 0.001). CONCLUSION: Smartphone addiction is highly prevalent among Indian adolescents and is significantly associated with urban living, higher socioeconomic status, non-authoritative parenting styles, and poor mental health. These findings underscore the need for digital literacy programs, parenting interventions promoting authoritative styles, and mental health support to foster healthy smartphone use among adolescents.

Exploring the association between internet addiction and time management among undergraduate nursing students.

BACKGROUND: Modern undergraduate nursing students face unique challenges as digital natives balancing internet activities with the substantial academic demands of nursing studies. Given the detrimental effects of internet addiction on students' academic performance and well-being, having time management skills is crucial. AIMS: To assess the prevalence and levels of internet addiction and time management and their association among undergraduate nursing students. DESIGN: A cross-sectional, survey-based research design was used. SETTING: The Faculty of Nursing at Alexandria University in Egypt. SUBJECTS: A stratified random sample consisting of 825 undergraduate nursing students. TOOLS: The internet addiction test and time management questionnaire were utilized to collect data. FINDINGS: Internet addiction was prevalent among 98.8% of students, with 56.0% exhibiting mild levels, 40.0% showing moderate levels, and 2.8% having severe levels. A statistically significant negative correlation was found between students' internet addiction and overall time management (r= - 0.387, p < 0.001). CONCLUSION: A considerable level of internet addiction was revealed among the great majority of undergraduate nursing students; however, many students also demonstrated strong time management skills. Furthermore, internet addiction and overall time management were negatively associated, indicating that students with higher levels of internet addiction tend to have poorer time management abilities. RECOMMENDATIONS: Individual counseling and educational training programs should be developed to teach nursing students how to manage time and effectively plan internet usage.

Cannabidiol or ketamine for preventing the impact of adolescent early drug initiation on voluntary ethanol consumption in adulthood.

Background: Few studies have previously evaluated the long-term impact of initiating the combined use of alcohol and cocaine early-in-life during adolescence. Our preclinical study characterized changes in affective-like behavior and/or voluntary ethanol consumption emerging later on in adulthood induced by a prior adolescent drug exposure, as well as tested therapeutical interventions (i.e., cannabidiol or ketamine) to prevent the observed effects. Methods: We performed three independent studies with male and female Sprague-Dawley rats, treated in adolescence (postnatal days, PND 29-38) with non-contingent paradigms of ethanol, cocaine, their combination or vehicle. Later on, adult rats were (1) scored for their affective-like state (forced-swim, elevated-plus maze, novelty-suppressed feeding, sucrose preference), (2) allowed to freely drink ethanol for 6 weeks (two-bottle choice), or (3) treated with cannabidiol or ketamine before given access to ethanol in adulthood. Results: No signs of increased negative affect were observed in adulthood following the adolescent treatments. However, adolescent ethanol exposure was a risk-factor for later developing an increased voluntary ethanol consumption in adulthood, both for male and female rats. This risk was similar when ethanol was combined with adolescent cocaine exposure, since cocaine alone showed no effects on later ethanol intake. Finally, rats exposed to adolescent ethanol and pretreated in adulthood with cannabidiol (and/or ketamine, but just for females) reduced their ethanol voluntary consumption. Conclusion: Our data provided two therapeutical options capable of preventing the impact of an early drug initiation during adolescence by decreasing voluntary ethanol consumption in adult rats.

Navigating opioid use in chronic noncancer pain conditions: A case series on pseudoaddiction.

Opioid prescriptions for chronic non-cancer pain raise concerns of addiction risks. Understanding the nuanced intersection of chronic pain and opioid use is crucial in clinical settings. We present four case studies from two tertiary care hospitals illustrating the phenomenon of "pseudoaddiction" in CNCP referred to addiction specialists for management. Each case involves complex pain presentations like pancreatitis, avascular necrosis, and SLE intertwined with escalating opioid demands. Management involved psychoeducation, CBT, and opioid substitution, resulting in reduced pain and need for opioids. Differentiating between addiction and uncontrolled pain is crucial for tailored management, emphasizing individualized care for improved outcomes.
