The Effects of Problematic Internet Use and Emotional Connotation on Internet Slang Processing: Evidence from a Lexical Decision Task.

Young people use slang for identifying themselves with a particular social group, gaining social recognition and respect from that group, and expressing their emotional state. One feature of Internet slang is its active use by youth in online communication, which, under certain conditions, may cause problematic Internet use (PIU). We conducted two studies in young Russian speakers (n1 = 115, n2 = 106). In study 1, participants were asked to rate a set of slang and common words using Self-Assessment Manikin. The study revealed that the most reliable predictor of higher emotional ratings was word familiarity. There were no significant effects of slang vs. common words or word frequency. In study 2, we used a dual lexical decision task to reveal the effects of word characteristics and propensity for PIU on reaction time (RT) for Internet slang words in pairs with semantically related vs. unrelated common words. Study 2 did not reveal any significant semantic priming effect. Word frequency was a significant predictor of lexical decision facilitation. Common, but not slang, word valence and dominance significantly affected RT in the opposite direction. Individuals with higher cognitive preoccupation with the Internet responded significantly faster, while those more likely to use online communication for mood regulation responded significantly slower to the stimuli. Apparently, on explicit and implicit levels, in-depth knowledge of Internet slang can be one the PIU markers. The results are discussed in line with Davis' approach to determining the general pathological Internet use.

The mediating effect of subject well-being between physical activity and the internet addiction of college students in China during the COVID-19 pandemic: a cross-sectional study.

Background: Internet addiction poses a significant threat to the health of college students worldwide, but physical activity, as a highly safe and effective rehabilitative measure, has shown promise for alleviating this issue nowadays. However, during the COVID-19 pandemic, the mediating processes in this association remained unclear. This study aims to explore the impact of physical activity on internet addiction among college students and the mediating role of subjective well-being. Methods: A survey was conducted on 216 eligible college students using the physical activity level scale, the internet addiction test, and the subjective well-being scale. For data analysis, independent sample t-tests, correlation analysis, hierarchical regression analysis, and mediating effect tests were in turn carried out in this work. Results: The study revealed noteworthy gender disparities in physical activity and internet addiction among college students (ß = -0.356, p < 0.01; ß = 0.140, p < 0.05). Compared to females, male students manifest elevated levels of physical activity and lower scores in internet addiction. Physical activity and subjective well-being exerted a significantly negative predictive influence on internet addiction (ß = -0.162, p < 0.05; ß = -0.508, p < 0.001). What's more, subjective well-being assumed a crucial mediating role in the relationship between physical activity and internet addiction, with the mediating effect accounting for 72.81% of the total effect. Conclusion: This study deepens the understanding of how physical activity reduces internet addiction risk while emphasizing that enhancing subjective well-being is an effective strategy for college students to cope with Internet addiction.

Prevalence and factors associated with digital addiction among students taking university entrance tests: a GIS-based study.

BACKGROUND: The surge in digital media consumption, coupled with the ensuing consequences of digital addiction, has witnessed a rapid increase, particularly after the initiation of the COVID-19 pandemic. Despite some studies exploring specific technological addictions, such as internet or social media addiction, in Bangladesh, there is a noticeable gap in research focusing on digital addiction in a broader context. Thus, this study aims to investigate digital addiction among students taking the university entrance test, examining its prevalence, contributing factors, and geographical distribution using GIS techniques. METHODS: Data from a cross-sectional survey were collected from a total of 2,157 students who were taking the university entrance test at Jahangirnagar University, Bangladesh. A convenience sampling method was applied for data collection using a structured questionnaire. Statistical analyses were performed with SPSS 25 Version and AMOS 23 Version, whereas ArcGIS 10.8 Version was used for the geographical distribution of digital addiction. RESULTS: The prevalence of digital addiction was 33.1% (mean score: 16.05 ± 5.58). Those students who are attempting the test for a second time were more likely to be addicted (42.7% vs. 39.1%), but the difference was not statistically significant. Besides, the potential factors predicted for digital addiction were student status, satisfaction with previous mock tests, average monthly expenditure during the admission test preparation, and depression. No significant difference was found between digital addiction and districts. However, digital addiction was higher in the districts of Manikganj, Rajbari, Shariatpur, and Chittagong Hill Tract areas, including Rangamati, and Bandarban. CONCLUSIONS: The study emphasizes the pressing need for collaborative efforts involving educational policymakers, institutions, and parents to address the growing digital addiction among university-bound students. The recommendations focus on promoting alternative activities, enhancing digital literacy, and imposing restrictions on digital device use, which are crucial steps toward fostering a healthier digital environment and balanced relationship with technology for students.

Anxiety and depression during post covid-19 lockdown period among medical students, and it's relation with stress and smartphone addiction in India.

OBJECTIVES: Medical profession, a competitive and ever-updating field which requires great commitment, imposes a stressful environment for students. Our study aimed to find the prevalence and factors associated with psychological illness. METHODS: A cross-sectional analytical study was done among medical students in Puducherry. A stratified random sampling strategy was incorporated to achieve a calculated sample size of 384. The presence of anxiety and depression, perceived stress and addiction to the phone were assessed using the Hospital Anxiety and Depression Scale, Perceived Stress Scale, and Smartphone Addiction Scale - short version. Prevalence of anxiety and depression was summarized as a proportion with a 95 % confidence interval (CI). The prevalence ratio (PR) for the factors associated was estimated using log-binomial regression. RESULTS: With the response from 383 students, the prevalence of anxiety and depression was 39.4 % (95 %CI: 34.5-44.3 %) and 26.6 % (22.2-31.1 %). Perceived stress was moderate in 68.2 % and high in 14 % of students. Higher age (aPR=1.49), female gender (aPR=1.22), tobacco or alcohol use (aPR=1.24), smartphone addiction (aPR=2.09) and high stress (aPR=1.93) were the predictors of anxiety among medical students in our study. Use of tobacco or alcohol (aPR=2.07), smartphone addiction (aPR=1.96) and high stress (aPR=1.72) were the predictors of depression. CONCLUSIONS: Anxiety was more prevalent than depression among the medical students. Use of tobacco or alcohol, smartphone addiction and stress increase the risk of psychological morbidity. Medical training should have a module on coping mechanisms to overcome psychological illness and have better mental well-being.

The Vicious Cycle between Loneliness and Problematic Smartphone Use among Adolescents: A Random Intercept Cross-Lagged Panel Model.

Despite extensive research on the psychological impacts of digital technology, the nuanced dynamics between adolescent loneliness and problematic smartphone use, particularly across different educational levels and genders, remain underexplored. This study aims to fill this gap by employing a Random Intercept Cross-Lagged Panel Model to dissect the bidirectional relationship between loneliness and problematic smartphone use among adolescents, with a focus on the moderating roles of educational levels and gender. Engaging 3132 students from various educational institutions in China, the research conducted a three-wave longitudinal analysis across 2022-2023. The final number of participants included 1120 adolescents (53.5% female; age in 2022: M = 14.57 years, SD = 1.57). Results reveal that loneliness significantly predicts problematic smartphone use, but not vice versa, highlighting a unidirectional influence. The study uncovers crucial differences across educational levels and gender, emphasizing the stronger effect of loneliness on problematic smartphone use among junior high students and female adolescents. These findings underscore the complexity of adolescent loneliness and its relationship with digital behavior, suggesting a need for tailored interventions considering both gender and developmental stages.

Investigating the effects of postural habits and awareness on early adolescent's internet addiction levels.

OBJECTIVES: Early adolescence is a period of growth and development determined by the onset of puberty, during which important changes in psychological development and social roles occur. Excessive use of the internet, especially in adolescents in this period, causes health problems such as postural disorders, vision problems, sedentary life, and unbalanced nutrition. When the studies are analyzed, it is observed that postural disorders are observed in children and adolescents. This study was planned to investigate the effect of postural habits and awareness on the level of internet addiction in early adolescents. METHODS: Physical characteristics of the participants (age, height, weight, gender, body mass index) were recorded. Duration and purpose of internet use and internet addiction were determined with the Young Internet Addiction Test-Short Form, body composition sensitivity level with the Body Awareness Questionnaire, and postural awareness with the Postural Habit and Awareness Scale. RESULTS: There was a significant positive correlation between internet addiction and duration of internet use (r=0.466) (p=0.000). In addition, there was no relationship between internet usage time and body awareness (r=-0.117) (p=0.084) and postural awareness and habit (r=-0.017) (p=0.798). When internet addiction was compared with body awareness, a significant relationship was found in the opposite direction (r=-0.145) (p=0.031). When internet addiction was compared with postural awareness and habit, a positive relationship was found (r=0.190) (p=0.005). CONCLUSIONS: Our study showed that internet addiction negatively affects body awareness, and does not affect postural habits, but positively affects postural awareness.

Exploring the determinants of internet addiction among Peri-urban adolescents (aged 13-18) in Delhi-NCR, India: an ordered logit model analysis.

OBJECTIVES: In recent years, there has been phenomenal growth in internet usage worldwide, with a substantial proportion of children and adolescents actively engaging with online platforms. While the internet presents numerous opportunities for children and adolescents, the lack of digital literacy and adequate online safety measures exposes them to various cybercrimes, including cyberbullying, cyberstalking, identity theft, and sexual predation. Moreover, there is growing concern regarding internet addiction among this population. METHODS: To investigate the determinants of internet addiction among adolescents, we conducted a cross-sectional study in peri-urban Delhi-NCR, India. We used a self-administered questionnaire to gather information on internet usage, and 630 adolescents aged 13-18 participated in the study, also completing an Internet Addiction Test. RESULTS: The findings indicate that 415 adolescents (65.9 %) exhibited no signs of internet addiction, suggesting a healthy relationship with the internet. However, 215 adolescents (33.1 %) displayed symptoms of internet addiction. Among those exhibiting internet addictions, 159 (74.0 %) were classified as mild internet addicts, indicating moderate levels of internet usage. Furthermore, 56 (26.0 %) adolescents were classified as moderate internet addicts, reflecting a higher level of internet addiction. CONCLUSIONS: Our study highlights the significant influence of various factors, including family dynamics, environmental factors, and personal experiences, on internet addiction among adolescents. Based on these findings, we propose implementing measures at different levels to foster responsible internet use among adolescents, thereby substantially reducing internet addiction.

Parental Phubbing and Adolescent Smartphone Addiction: Depression and Perceived School Climate Matter.

This study investigated the association between parental phubbing and adolescents' smartphone addiction, the mediating role of depression, and the moderating role of perceived school climate in the association. Seven hundred forty-two Chinese adolescents (Mage = 12.97, SD = 0.64, 45.55 percent female) were recruited and self-reported questionnaires were administered. Results indicated that parental phubbing was positively associated with adolescents' smartphone addiction. Depression partially mediated the above relation. Further, perceived school climate moderated the relation between parental phubbing and depression, such that the positive association between parental phubbing and depression was stronger among adolescents who perceived their school climate as more negative (vs. positive). The findings deepened our understanding of the relation between parenting behaviors and adolescents' smartphone addiction and implications for interventions and practices were discussed.

Social media addiction and depression and their predictors among university students.

OBJECTIVES: Social media facilitate the interaction between individuals without regard to the distances between the users. Everybody who has access to internet can suffer from social media addiction. During COVID-19 pandemic there was an increase in social media usage among all population types and especially the university students, which would negatively affect their mental health. Therefore, this study aims at assessing social media addiction and depression among pharmacy students by using questionnaires specifically designed for this purpose. METHODS: A cross-sectional study with convenience sampling was conducted from the start of November to the end of December 2021 among undergraduate pharmacy students in Mosul city, Iraq. An online questionnaire was adopted; it consisted of three parts, the first was for collecting socio-demographic and social media usage information, Social Media Addiction Questionnaire (SMAQ) was used in the second part to assess social media addiction of the participants, and the third part was comprised of the Patient Health Questionnaire (PHQ-9) to assess depression among students. RESULTS: Six hundred-three students completed the questionnaire and constituted the final study sample. Instagram was the most used social media program among the students. About 38 % of the students were at risk of becoming addicted on social media, with only 8.4 % of them being minimally or not depressed. Additionally, positive significant correlation was observed between social media addiction and depression. Using social media for more than 4 h and poor academic performance were found to be predictors for social media addiction and depression. CONCLUSIONS: Addiction to social media and depression are prevalent among pharmacy students in Iraq and the two are related to each other.

The relationship between chronotype, psychological pain, problematic social media use, and suicidality among university students in Turkey.

Chronotype has been extensively linked to various psychological outcomes, including suicide, which significantly impacts the mortality rate among young adults worldwide. Research on the extent of these links is still ongoing. This cross-sectional study aimed to explore the complex relationships between chronotype, internet addiction, problematic social media use (PSMU), psychological pain, and suicidality in a student population. A total of 571 Turkish students (65.3% female, mean age 20.3 ± 1.63 years) completed the following scales: the Suicide Probability Scale (SPS), the Mee-Bunney Psychological Pain Assessment Scale (MBPPAS), the Social Media Disorder Scale (SMDS), the Internet Addiction Test (IAT), the Morningness - Eveningness Questionnaire (MEQ), and the Hospital Anxiety and Depression Scale (HADS). The results showed that the relationship between chronotype and suicidality was partially mediated by SMDS and MBPPAS but not by anxiety, depression, or IAT. These findings suggest that psychological pain and PSMU may be important factors that contribute to suicidality in evening-type individuals. These findings have significant implications for the development of interventions aimed at reducing suicidality among evening-type individuals. By addressing the underlying factors of psychological pain and PSMU, it may be possible to mitigate the increased risk of suicidality among this population.

Video games and Facebook addiction among Tunisian adolescents: prevalence and associated factors.

OBJECTIVES: As social media and online gaming technology have developed very rapidly over the last two decades, their paired issues are of growing concern worldwide. The aim of our study was to assess the prevalence of video game and Facebook addiction and its predictive factors among Tunisian in school adolescents. METHODS: We conducted a cross-sectional study among in school adolescents in Sousse, Tunisia, over the first academic term of the 2019-2020 school year using a self-administered questionnaire to a randomly selected representative sample of 1,353 students. The valid Arabic version of the Bergen Facebook Addiction Scale (BFAS), the Video Game Addiction Scale (GAS-7), the Beck Depression Inventory Short Form (13 items) and the Screen for Child Anxiety Related Disorders (SCARED-C) were used to assess facebook addiction disorder (FAD), internet gaming disorder (IGD), depression and anxiety respectively. RESULTS: More than one in four pupils (26.1 %; CI 95 %: 23.8-28.4 %) were identified as problematic video game users and almost a third of participants (32.5 %; CI 95 %: 30-35 %) reported FAD. IGD was significantly associated with FAD (p<0.001). Likewise, pupils exhibiting depressive symptoms as well as those with anxiety symptoms were significantly more likely to be problematic video games and Facebook users (p<0.001 for each). Being addicted to Facebook (AOR=1.83, 95 % CI: 1.18-2.81), experiencing anxiety disorders (AOR=2.43, 95 % CI: 1.52-3.88), being male (AOR=2.51, 95 % CI: 1.95-3.23) and spending more than 4 h per day surfing the net (AOR=2.55, 95 % CI: 1.65-3.96) were the determinants of IGD in the multivariate analysis. Similarly, being addicted to video games (AOR=1.82, 95 % CI: 1.21-2.73), experiencing anxiety disorders (AOR=1.85, 95 % CI: 1.20-2.86), having experienced academic failure (AOR=1.73, 95 % CI: 1.16-2.56), and spending more than 4 h per day on social media (AOR=3.75, 95 % CI: 2.38-5.90) were the predictors of FAD. CONCLUSIONS: The prevalence of problematic use of video games and Facebook is alarmingly high. Identifying risk factors can help screen high-risk adolescents. We need additional prevention measures addressing not just adolescents, but all risk factors.

Health Economic Evaluation of an Online-Based Motivational Program to Reduce Problematic Media Use and Promote Treatment Motivation for Internet Use Disorder-Results of the OMPRIS Study.

Internet Use Disorders (IUD) have a relevant effect on national economies. In the randomized, controlled, multicenter, prospective, and single-blinded OMPRIS study (pre-registration number DRKS00019925; Innovation Fund of the Joint Federal Committee of Germany, grant number 01VSF18043), a four-week online program to reduce media addiction symptoms, was evaluated for cost-effectiveness. The intervention group (IG) was compared to a waiting control group (WCG) from German statutory health insurance (SHI) and a societal perspective. Resource use, namely indirect and direct (non) medical costs, was assessed by a standardized questionnaire at baseline and after the intervention. Additionally, intervention costs were calculated. Determining the Reliable Change Index (RCI) based on the primary outcome, assessed by the "Scale for the Assessment of Internet and Computer Game Addiction" (AICA-S), individuals with and without reliable change (RC) were distinguished. The incremental cost-effectiveness ratio was calculated using the difference-in-difference approach. There were 169 (IG n = 81, WCG n = 88) persons included in the analysis. The mean age was 31.9 (SD 12.1) years. A total of 75.1% were male, and 1.8% diverse. A total of 65% (IG) and 27% (WCG) had an RC. The cost per person with RC was about EUR 860 (SHI) and EUR 1110 (society). The intervention leads to an improvement of media addiction symptoms at moderate additional costs.

The COVID-19 related stress and social network addiction among Chinese college students: A moderated mediation model.

Based on social cognitive theory and gender differences, this study verified a moderated mediation model to explore the relationship between the COVID-19 related stress (CRS) and social network addiction (SNA) and evaluate the mediating role of fear of missing out (FoMO) and the moderating role of gender. A questionnaire survey was conducted, including 702 Chinese university students.This study used PROCESS to test the hypothesis model.The results showed that the CRS significantly and positively affected the SNA of college students and FoMO played a complementary mediating role. Moreover, the analysis of the moderated mediation model showed that gender moderated the relationship between FoMO and SNA; the effect of FoMO was stronger on the SNA of male college students than that of females. The results not only enhanced our understanding of the internal influencing mechanism of the relationship between CRS and SNA but also considered gender differences. In addition, some suggestions were proposed.

More grateful, less addicted! Understanding how gratitude affects online gaming addiction among Chinese college students: a three-wave multiple mediation model.

BACKGROUND: Online game addiction has become a prominent public concern, particularly among emerging adults, warranting in-depth investigation. Despite prior cross-sectional research indicating a negative correlation between gratitude and online gaming addiction, a dearth of longitudinal research exists in this area. Furthermore, the underlying mechanisms that explain the link between gratitude and online gaming addiction remain poorly understood, highlighting a critical research gap in the field. METHODS: To bridge this gap, our study adopted a three-wave longitudinal design and constructed a multiple mediation model. Over the course of one year, data was collected from a sample of Chinese undergraduates, with 319 students participating at Time 1, 305 at Time 2, and 292 at Time 3. Participants were administered online self-report surveys, enabling the acquisition of valuable data regarding their levels of gratitude, online game addiction, self-control, and loneliness. RESULTS: The findings revealed a negative correlation between gratitude measured at Time 1 and online game addiction assessed at Time 3. Further analysis demonstrated that both self-control and loneliness played multiple mediating roles at Time 2 in the link between gratitude and online game addiction. CONCLUSION: These research findings shed light on the underlying mechanisms between gratitude and online game addiction, which provide implications for developing interventions (e.g., interventions based on gratitude) for reducing young adults' online game addiction.

Longitudinal relationships between school assets, traditional bullying, and internet gaming disorder: the role of self-control and intentional self-regulation among Chinese adolescents.

Introduction: Although developmental assets have been proven to be enabling factors for both adolescent traditional bullying and internet gaming disorder (IGD), there is a lack of empirical evidence that has investigated the direct relationship between school assets and both of these problematic behaviors concurrently. Based on the positive youth development (PYD) perspective, the present study aimed to explore the relationship between school assets, intentional self-regulation (ISR), self-control, traditional bullying, and IGD among Chinese adolescents. Methods: A total of 742 middle school students (Mage = 13.88 years, SD = 1.99 years) were followed up to measure school assets, ISR, self-control, traditional bullying, and IGD in two waves that were separated by 5 months. Results: Structural equation modeling (SEM) indicated that T1 school assets negatively predicted T2 traditional bullying and T2 IGD. T1 self-control significantly mediated the relationships between T1 school assets and T2 traditional bullying, as well as between T1 school assets and T2 IGD. Additionally, T1 ISR strengthened the positive effect of T1 school assets on T1 self-control and further moderated the two mediating paths. Discussion: These findings show that plentiful school assets support the development of self-control and are more successful in reducing traditional bullying and IGD, particularly among students with higher ISR. As a result, schools should take measures to provide superior-quality assets for the positive development of youth, which will help to prevent and relieve traditional bullying and IGD in the school context.

Problematic internet gaming and non-suicidal self-injury in Chinese adolescents: Moderating and mediating roles of anxiety.

INTRODUCTION: Despite consistent reports of the association between problematic internet gaming (PIG) and non-suicidal self-injury (NSSI), an increase in PIG does not necessarily lead to increased NSSI. This apparent paradox indicates the presence of other mediators and moderators in the PIG-NSSI association. This study aimed to investigate the role of anxiety as a potential moderating and mediating factor of the PIG-NSSI association in Chinese adolescents. METHODS: A cross-sectional study was conducted among 10,479 Chinese adolescents (50.5% male; age range, 9-18 years). Standardized self-report questionnaires were used to assess the severity of PIG, anxiety, and NSSI. Spearman correlation and multiple linear regression were applied to examine the relationships among PIG, anxiety, and NSSI. Both moderating and mediating effects of anxiety were assessed using Hayes' methods. RESULTS: PIG, anxiety symptoms, and NSSI significantly correlated with one another. Anxiety significantly moderated the relationship between PIG and NSSI [B = 0.002, standard error (SE) = 0.000, p < 0.001], and it partially mediated the PIG-NSSI association [B = 0.017, SE = 0.001, 95% confidence interval (CI) 0.014-0.021]. Social concern and concentration were the two dimensions of anxiety that exerted the strongest mediation effect (B = 0.017, SE = 0.002, 95% CI 0.014-0.020). CONCLUSIONS: Adolescents with PIG and high anxiety are likely to suffer more severe NSSI and may benefit from interventions to reduce anxiety symptoms.

Relationship between Materialism and Social Networking Site Addiction among Adolescents: A Moderated Mediation Model.

Materialism has been consistently linked to Internet-related addictions, including compulsive online shopping, problematic online gaming, and excessive smartphone use; however, the relationship between materialism and social networking site (SNS) addiction has remained unclear. Thus, this study aims to examine the association between materialism and SNS addiction and investigate the mediating effect of fatalism and moderating effect of self-concept clarity in this relationship among 703 Chinese adolescents. Materialism was significantly positively associated with SNS addiction in adolescents, and fatalism partially mediated this association. Moreover, self-concept clarity moderated the direct and indirect relationships between materialism and SNS addiction. Specifically, for adolescents with low (versus high) self-concept clarity, those who also had high levels of materialism were more likely to develop fatalistic beliefs and showed further symptoms of SNS addiction. This study's findings imply that decreasing materialism and fatalism and developing self-concept clarity might be effective interventions for reducing SNS addiction among adolescents.

The Correlation between Social Media Addiction and Emotional Eating during the COVID-19 Quarantine Period.

This study was conducted with 458 participants. The demographic and health information of the participants along with the Social Media Addiction, Emotional Eating Scale were obtained. The level of social media addiction in adults was moderate, and women were more interested in social media than men. As the average age of participants increased, the virtual tolerance, virtual communication, social media scores decreased (p < .05). The study found that 51.6% of individuals with emotional eating tendencies happened to be obese. The social media addiction scale scores of those with emotional eating tendencies were higher than those without emotional eating tendencies (p < .05).

Think-aloud analysis of commonly used screening instruments for Internet use disorders: The CIUS, the IGDT-10, and the BSMAS.

Background: Despite the constant publication of new screening instruments for Internet use disorders (IUD), little is known about their content validity. This study aimed to identify potential mismatches between the items' intention and young adults' interpretation of these items when answering three screening instruments that are commonly used in research and clinical settings: The Compulsive Internet Use Scale (CIUS), the 10 Item-Internet Gaming Disorder Test (IGDT-10), and the Bergen Social Media Addiction Scale (BSMAS). Methods: In total, 30 vocational students (50% female, age = 21.3; SD = 2.1) took part in individual think-aloud interviews. All participants were asked to report their thoughts while completing the CIUS. In addition, participants who reported online games (OG) as their main Internet activity (n = 11) answered the IGDT-10. Participants who reported social networks (SN) as their main Internet activity (n = 18) answered the BSMAS. One participant used OG and SN equally and completed both screening instruments. All interviews were audio-recorded, transcribed, and content-analysed. Results: Overall, four potential sources for errors were identified: (1) High scorings were often not congruent with the underlying diagnostic criteria. In particular, such discrepancies were found in items aimed to assess dysfunctional emotional regulation strategies and cognitive involvement. (2) Some participants were uncertain which time frame or Internet activity should be considered in their answers. (3) Long and complex items led to the building of mean values or the choice of the middle answer category. (4) Some wordings were perceived to be outdated and difficult to understand. Discussion: These findings might help to provide recommendations on how to improve screening instruments for IUD. Most important, items should more clearly distinguish between Internet use as a "normal" leisure activity and Internet use that leads to functional impairments in daily life.

Effects of retrieval-extinction training on internet gaming disorder.

Background and aims: Internet gaming disorder (IGD) leads to serious impairments in cognitive functions, and lacks of effective treatments. Cue-induced craving is a hallmark feature of this disease and is associated with addictive memory elements. Memory retrieval-extinction manipulations could interfere with addictive memories and attenuate addictive syndromes, which might be a promising intervention for IGD. The aims of this study were to explore the effect of a memory retrieval-extinction manipulation on gaming cue-induced craving and reward processing in individuals with IGD. Methods: A total of 49 individuals (mean age: 20.52 ± 1.58) with IGD underwent a memory retrieval-extinction training (RET) with a 10-min interval (R-10min-E, n = 24) or a RET with a 6-h interval (R-6h-E, n = 25) for two consecutive days. We assessed cue-induced craving pre- and post-RET, and at the 1- and 3-month follow-ups. The neural activities during reward processing were also assessed pre- and post-RET. Results: Compared with the R-6h-E group, gaming cravings in individuals with IGD were significantly reduced after R-10min-E training at the 3-month follow-up (P < 0.05). Moreover, neural activities in the individuals with IGD were also altered after R-10min-E training, which was corroborated by enhanced reward processing, such as faster responses (P < 0.05) and stronger frontoparietal functional connectivity to monetary reward cues, while the R-6h-E training had no effects. Discussion and Conclusions: The two-day R-10min-E training reduced addicts' craving for Internet games, restored monetary reward processing in IGD individuals, and maintained long-term efficacy.
