Life Satisfaction and Online-Gambling Communities: A Cross-National Study of Gambling Activities Among Young Finnish, American, South Korean and Spanish People.

Gambling is a potential hazard to life satisfaction, yet peer relationships online might buffer this risk. This study analyzed the ways problem gambling is associated with life satisfaction as well as the extent to which the use of online-gambling community participation and, alternatively, offline belonging affect this association. A web-based survey was conducted among people aged 15-25 in Finland (n = 1,200), the United States (n = 1,212), South Korea (n = 1,192), and Spain (n = 1,212). The main variables included life satisfaction, problem gambling measured by the South Oaks Gambling Screen, online-gambling community participation, and offline belonging. Controls included compulsive internet use, hazardous drinking, psychological distress, income, age, and gender. Linear regression models were employed with country interactions. Results showed problem gambling had a negative relationship with life satisfaction, but the association was explained by control variables. Online-gambling community participation had a positive relationship with life satisfaction, especially among pathological gamblers who had poor offline relationships. Country comparisons revealed that the direct effect of excessive gambling and the compensating effect of online-gambling communities were most prominent in Finland.

Professional Social Media Usage and Work Engagement Among Professionals in Finland Before and During the COVID-19 Pandemic: Four-Wave Follow-Up Study.

BACKGROUND: The COVID-19 pandemic has changed work life profoundly and concerns regarding the mental well-being of employees' have arisen. Organizations have made rapid digital advancements and have started to use new collaborative tools such as social media platforms overnight. OBJECTIVE: Our study aimed to investigate how professional social media communication has affected work engagement before and during the COVID-19 pandemic and the role of perceived social support, task resources, and psychological distress as predictors and moderators of work engagement. METHODS: Nationally representative longitudinal survey data were collected in 2019-2020, and 965 respondents participated in all 4 surveys. Measures included work engagement, perceived social support and task resources, and psychological distress. The data were analyzed using a hybrid linear regression model. RESULTS: Work engagement remained stable and only decreased in autumn 2020. Within-person changes in social media communication at work, social support, task resources, and psychological distress were all associated with work engagement. The negative association between psychological distress and work engagement was stronger in autumn 2020 than before the COVID-19 outbreak. CONCLUSIONS: The COVID-19 pandemic has exerted pressure on mental health at work. Fostering social support and task resources at work is important in maintaining work engagement. Social media communication could help maintain a supportive work environment.

Online dating applications and risk of youth victimization: A lifestyle exposure perspective.

Based on lifestyle exposure theory (LET), this study examined online dating application (ODA) use and victimization experiences among adolescents using large cross-national samples of Finnish, American, Spanish, and South Korean young people between ages 15 and 18. According to logistic regression analyses in two substudies, ODA use was associated with more likely victimization to online harassment, online sexual harassment, and other cybercrimes and sexual victimization by adults and peers. According to mediation analyses, this relationship was mainly accounted for by the fact that ODA users engage in more risky activities in online communication and information sharing. Attention should be paid to the risks ODAs pose to vulnerable groups, such as young people, with insufficient skills to regulate their social relationships online.

The Role of Virtual Communities in Gambling and Gaming Behaviors: A Systematic Review.

Gambling opportunities are facilitated by the growth of the Internet and social media platforms. Digital games also increasingly include monetary features, such as microtransactions, blurring the line between gambling and gaming. The Internet provides a variety of virtual communities for gamblers and gamers, but comprehensive research on these communities and their relevance in gambling and monetary gaming behaviors remains scarce. This paper summarizes research of online gambling and monetary gaming communities based on a systematic literature review. A systematic literature search was conducted from five databases: Scopus, Web of Science, PsycINFO, Social Science Premium Collection, and EBSCOhost. The search was limited to empirical articles that focused on gambling or gaming involving money and examined online interaction between gamblers or gamers. Preliminary search resulted in 1056 articles, from which 55 were selected for the analyses based on pre-determined criteria. According to results, online communities serve different functions in gambling and gaming behaviors. Gambling communities are typically forums for discussing and sharing gambling experiences, strategies, and tips as well as gambling problems, while gaming communities are inherently embedded inside a game being an essential part of the gaming experience. Identification with virtual communities influences gambling behavior and monetary gaming behavior through mechanisms of perceived norms, social influence, and community feedback. Whereas some gambling communities may provide protection from excessive gambling habits, gaming communities seem to solely motivate gaming behavior and purchase intentions. The role of online communities should be acknowledged in prevention and treatment of gambling and gaming problems.

The Association Between Social Media Use and Hazardous Alcohol Use Among Youths: A Four-Country Study.

AIMS: To examine the continuing role of daily popular social media use in youth hazardous alcohol consumption in four countries across continents. METHODS: A web-based survey was given to youths aged 15-25 in the USA (n = 1212), South Korea (n = 1192), Finland (n = 1200) and Spain (n = 1212). Hazardous alcohol use (alcohol use disorders identification test-C) was the dependent variable. Main independent variables measured daily use of different social media services. Controls included compulsive Internet use, offline belonging, psychological distress, impulsivity, risk-taking, age and gender. Linear regression models and mediation analyses with bootstrapping were done for each country. RESULTS: Daily use of Facebook and Instagram was associated with higher hazardous alcohol use among youths in Finland, South Korea and Spain. Daily instant messaging was related to higher hazardous alcohol use among South Korean and Finnish youths. Daily YouTube use was associated with higher hazardous alcohol use among youths in South Korea, but lower hazardous alcohol use among youths in the USA and Finland. Daily Twitter use was related to lower hazardous drinking among youths in Finland but higher hazardous drinking among youths in Spain. The mediation analyses revealed that uploading pictures to social media is a possible facilitator of social media-related hazardous alcohol use among youths in the USA and Spain. CONCLUSION: Certain social media platforms might inspire and/or attract hazardously drinking youths, contributing to the growing opportunities for social media interventions.

Peer Group Identification as Determinant of Youth Behavior and the Role of Perceived Social Support in Problem Gambling.

Gambling opportunities have increased rapidly during recent years. Previous research shows that gambling is a popular activity among youth, which may contribute to problem gambling. This study examined how social identification with online and offline peer groups associates with youth problem gambling behavior and if perceived social support buffers this relationship. Data were gathered with an online survey with 1212 American and 1200 Finnish participants between 15 and 25 years of age. Measures included the South Oaks Gambling Screen for problem gambling, and items for peer group identification and perceived social support. It was found that youth who identify strongly with offline peer groups were less likely to engage in problem gambling, while strong identification with online peer groups had the opposite effect. We also found that the associations between social identification and problem gambling behavior were moderated by perceived social support. Online peer groups may be a determinant in youth problem gambling. Focusing on offline peer groups and increasing social support can hold significant potential in youth gambling prevention.

Problem gambling and psychological distress: a cross-national perspective on the mediating effect of consumer debt and debt problems among emerging adults.

BACKGROUND: Severe economic difficulties are common among younger generations who currently have an easy access to consumer credit and payday loans in many Western countries. These accessible yet expensive short-term loans may lead to more severe financial difficulties, including default and debt enforcement, both which are defined as debt problems within this study. This study hypothesized that consumer debt and debt problems mediate the relationship between problematic gambling and psychological distress. Excessive gambling can be funded with consumer debt, which in turn leads to the accumulation of financial stressors and, eventually, psychological distress. METHODS: Three studies were conducted to examine the hypotheses. Study 1 used a demographically balanced sample of Finnish participants aged 18 to 25 years (n = 985, 50.76% female). Study 2 used a sample collected from Finnish discussion forums and social networking sites, with participants ranging from 18 to 29 years of age (n = 205, 54.63% female). Study 3 used a demographically balanced sample of American youths aged 18 to 25 years (n = 883, 50.17% female). Analyses were based on generalized structural equation models examining the role of problem gambling, consumer debt, and debt problems (i.e., default and debt enforcement) on psychological distress. Additional mediation analysis was run with treating both instant loans and debt problems as mediators. RESULTS: All three studies showed that problem gambling was associated with consumer debt, which was further associated with debt problems. Both consumer debt (studies 1 and 2) and debt problems (study 3) were associated with psychological distress. Problem gambling was also directly associated with psychological distress in studies 1 and 3, but not in study 2. In Finland, consumer debt mediated the relationship between problem gambling and psychological distress (studies 1 and 2), while study 3 underlined the mediating role of debt problems in the USA, where consumer debt itself was not positively associated with psychological distress. CONCLUSIONS: The results of the three studies indicate that problem gambling-related psychological distress is partly explained by consumer debt. Consumer credit and payday loans may provide resources for gamblers that enable them to keep up with the habit. This may eventually lead to debt problems and psychological distress. Cross-national differences exist, but in both Nordic and American models, similar mechanisms prevail. The results imply that limiting consumer debt among emerging adults could cushion the financial and psychological costs of problem gambling.

Excessive Gambling and Online Gambling Communities.

The Internet provides an accessible context for online gambling and gambling-related online communities, such as discussion forums for gamblers. These communities may be particularly attractive to young gamblers who are active Internet users. The aim of this study was to examine the use of gambling-related online communities and their relevance to excessive gambling among 15-25-year-old Finnish Internet users (N = 1200). Excessive gambling was assessed by using the South Oaks Gambling Screen. Respondents were asked in a survey about their use of various kinds of gambling-related online communities, and sociodemographic and behavioral factors were adjusted. The results of the study revealed that over half (54.33%) of respondents who had visited gambling-related online communities were either at-risk gamblers or probable pathological gamblers. Discussion in these communities was mainly based on sharing gambling tips and experiences, and very few respondents said that they related to gambling problems and recovery. In three different regression models, visiting gambling-related online communities was a significant predictor for excessive gambling (with 95% confidence level) even after adjusting confounding factors. The association of visiting such sites was even stronger among probable pathological gamblers than among at-risk gamblers. Health professionals working with young people should be aware of the role of online communities in terms of development and persistence of excessive gambling. Monitoring the use of online gambling communities as well as utilizing recovery-oriented support both offline and online would be important in preventing further problems. Gambling platforms should also include warnings about excessive gambling and provide links to helpful sources.

Proeating disorder websites and subjective well-being: A four-country study on young people.

OBJECTIVE: Proeating disorder (pro-ED) communities online encourage harmful weight-loss and weight-control practices. This study examined the association between exposure to pro-ED content online and subjective well-being (SWB) among adolescents and young adults in four countries. METHOD: Cross-national data were collected in the US, Germany, the UK and Finland from Internet users aged 15-30 years (N = 3,557; 50.15% male). The questionnaire assessed SWB, exposure to harm-advocating websites, online activity, prior victimization, and social belonging. Ordinary least squares (OLS) regression models assessed the relationship between SWB and pro-ED exposure and adjusted for a number of confounding factors. RESULTS: Of the participants, 17% had been exposed to pro-ED content (US 20%, Germany 7%, UK 21%, Finland 22%). Exposure to pro-ED content online was negatively associated with SWB in the US, Germany, and Finland, also after adjusting for the confounding factors. Offline social belonging moderated the association between pro-ED and SWB. DISCUSSION: Participants who visited pro-ED websites reported lower SWB than others did. The potentially harmful impact of visiting these sites was buffered by the strong offline social belonging. Given the observed similarities across the countries, it is important for families, health professionals, and educators to stay abreast of online communities that have possible contra recovery influences and to be able to discuss such Internet contents in a way that increases treatment motivation. © 2016 Wiley Periodicals, Inc.

Pro-Anorexia and Anti-Pro-Anorexia Videos on YouTube: Sentiment Analysis of User Responses.

BACKGROUND: Pro-anorexia communities exist online and encourage harmful weight loss and weight control practices, often through emotional content that enforces social ties within these communities. User-generated responses to videos that directly oppose pro-anorexia communities have not yet been researched in depth. OBJECTIVE: The aim was to study emotional reactions to pro-anorexia and anti-pro-anorexia online content on YouTube using sentiment analysis. METHODS: Using the 50 most popular YouTube pro-anorexia and anti-pro-anorexia user channels as a starting point, we gathered data on users, their videos, and their commentators. A total of 395 anorexia videos and 12,161 comments were analyzed using positive and negative sentiments and ratings submitted by the viewers of the videos. The emotional information was automatically extracted with an automatic sentiment detection tool whose reliability was tested with human coders. Ordinary least squares regression models were used to estimate the strength of sentiments. The models controlled for the number of video views and comments, number of months the video had been on YouTube, duration of the video, uploader's activity as a video commentator, and uploader's physical location by country. RESULTS: The 395 videos had more than 6 million views and comments by almost 8000 users. Anti-pro-anorexia video comments expressed more positive sentiments on a scale of 1 to 5 (adjusted prediction [AP] 2.15, 95% CI 2.11-2.19) than did those of pro-anorexia videos (AP 2.02, 95% CI 1.98-2.06). Anti-pro-anorexia videos also received more likes (AP 181.02, 95% CI 155.19-206.85) than pro-anorexia videos (AP 31.22, 95% CI 31.22-37.81). Negative sentiments and video dislikes were equally distributed in responses to both pro-anorexia and anti-pro-anorexia videos. CONCLUSIONS: Despite pro-anorexia content being widespread on YouTube, videos promoting help for anorexia and opposing the pro-anorexia community were more popular, gaining more positive feedback and comments than pro-anorexia videos. Thus, the anti-pro-anorexia content provided a user-generated counterforce against pro-anorexia content on YouTube. Professionals working with young people should be aware of the social media dynamics and versatility of user-generated eating disorder content online.

Preventing Religion-Based Hate Crime Victimization Among Youth: A Systematic Review of Personal, Collective, and Policy Responses.

Hate crime victimization targeting the victim's religious identity poses a serious problem for individuals, communities, and societies. This systematic review describes countermeasures to such victimization, aiming for broad descriptive inclusion by canvassing personal adaptations, collective programs, and institutional-governmental policies. Targeting peer-reviewed articles published between 2002 and 2022, we found 44 articles describing measures related to religion-based victimization prevention. We classified the studied measures into 12 main types. The most salient personal adaptations included camouflage-type blending in to avoid victimization, using religion as a source of resilience, and changing routines to deflect risk. At the collective level, mobilizing community resilience, stereotype reduction, and place-based solutions were often researched. The relatively few institutional-level studies addressed measures to enhance the connection between victims and authorities by various means. The experimental studies heavily concentrated on experiments supporting the efficacy of changing people's perceptions as a means of prevention. The review concludes with a discussion about research and policy implications.

Cyberharassment Victimization on Three Continents: An Integrative Approach.

This article introduces and applies an integrative model of cyberharassment victimization. The model combines routine activity theory (RAT), the general theory of crime (GTC), and the personal resources approach to analyze risk factors for victimization while acknowledging the protective role of a sense of mastery. Survey respondents were aged 15 to 25 years (N = 4816) from the U.S., Finland, Spain, and South Korea. Logistic regression models were used to analyze cyberharassment victimization. RAT-related factors were positively associated with cyberharassment victimization. Low self-control was positively associated with cyberharassment victimization in the U.S., Finland, and Spain but not in South Korea. The sense of mastery was negatively associated with cyberharassment victimization in the U.S., Finland, and South Korea but not in Spain. Protective factors against cyberharassment victimization should be utilized in future studies as adequate knowledge of protective factors could assist policymakers in generating preventative measures against cyberharassment. Our study demonstrates the benefits of integrating criminological theories and protective factors in studies using cross-national data to gain a better understanding of the dynamics of cyberharassment.

The Motivations for and Well-Being Implications of Social Media Use at Work among Millennials and Members of Former Generations.

Working life has digitalized considerably in recent decades and organizations have taken into use new forms of collaborative technologies such as social media platforms. This study examined the relationship between social media use at work and well-being at work for millennials and members of former generations in Finland. The research data contained focus group interviews (N = 52), an expert organization survey (N = 563), and a nationally representative survey (N = 1817). Well-being measures included technostress, burnout, psychological distress, and a set of background variables. Content analysis and linear regression models were used as analysis methods. The results showed that millennials have various intrinsic and extrinsic motivations for social media use at work. Intrinsic motivations included employees' personal choice and their pure interest to follow the market and discussions in their own field. Extrinsic motivations were related mainly to organizations' work culture and personal branding. The survey findings revealed, however, that millennials were not only more active social media users for work, but they also experienced higher technostress and burnout than members of former generations. Social media use motivations were associated with both higher and lower technostress and burnout depending on motivation, indicating that social media use can have both positive and negative effects. Overall, our findings suggest that employees tend to utilize social media more if their needs for autonomy, competence, and relatedness are fulfilled.

The Mediating Role of Psychological Distress in Excessive Gambling among Young People: A Four-Country Study.

BACKGROUND AND AIMS: Loneliness and a low sense of mastery are associated with excessive gambling, but the underlying processes of these relationships remain unstudied. Because psychological distress can increase vulnerability to excessive gambling, we investigated its mediating role in these relationships among young people. To meet the need for cross-country research, we also observed how these relationships occur in four countries with different cultures. DESIGN, SETTING, AND PARTICIPANTS: Demographically balanced cross-sectional survey data were collected from 15-25-year-olds in Finland (n = 1200; 50% male), the United States (n = 1212; 49.8% male), South Korea (n = 1192; 49.6% male), and Spain (n = 1212; 51.2% male). MEASUREMENTS: Excessive gambling was measured with the South Oaks Gambling Screen, psychological distress was assessed with the 12-item General Health Questionnaire, loneliness was measured with the three-item Loneliness Scale, and low sense of mastery was assessed with the Pearlin Mastery Scale. Associations were examined first using zero-inflated negative binomial regression analyses with excessive gambling as the outcome. In addition, path analyses were performed to study how loneliness and low sense of mastery relate to excessive gambling, with psychological distress as the mediating variable. FINDINGS: Loneliness and low sense of mastery were associated indirectly with excessive gambling via psychological distress in all country samples. Low sense of mastery was also directly associated with excessive gambling. There was a direct association between loneliness and excessive gambling only in samples from South Korea and Spain. CONCLUSIONS: Psychological distress is an important factor in understanding how loneliness and sense of mastery relate to gambling.

COVID-19 crisis and digital stressors at work: A longitudinal study on the Finnish working population.

The global crisis caused by the outbreak of a novel coronavirus and the associated disease (COVID-19) has changed working conditions due to social-distancing policies. Many workers started to use new technologies at work, including social media applications. In this longitudinal study, we investigated the potential stress effects of social media communication (SMC) at work. Based on our integrative theoretical model, we expected that SMC at work would burden some workers, but those who were accustomed to SMC at work would be better off when the crisis started. We collected a nationally representative sample of Finnish workers before (N = 1308) and during (N = 1081) the COVID-19 crisis. Outcome measures included technostress and work exhaustion. Multilevel linear mixed-effects regression models investigated formal and informal SMC at work. Covariates included cyberbullying at work, social media usage, personality, occupational status, and sociodemographic factors. Results showed that formal SMC increased and predicted higher technostress. However, technostress and work exhaustion decreased among workers already accustomed to using SMC at work before the crisis. The results indicate a disparity in workers' resilience during remote work and highlight a need for organizational level support.

Online Peers and Offline Highs: An Examination of Online Peer Groups, Social Media Homophily, and Substance Use.

Research indicates that youths are particularly susceptible to peer influence and that identifying with substance using peer groups predicts substance use. Today, youth spend more time interacting with distal peer groups via the Internet and have increased access to online drug cultures. Theoretically, this should have important implications for substance use. This study employs a nationally representative sample of U.S. youth (n = 1212), ages 15-25 years old, to examine whether online peer group identification and social media homophily predict substance use. Results indicate that online belonging and social media homophily are associated with some forms of substance use. While these factors were not significantly associated with regular marijuana or alcohol use among those who had initiated use, they predicted regular stimulant and opioid use among substance users. This suggests that online peer groups may promote progression into more problematic forms of substance use. Additional analyses of adolescent and young adult subgroups revealed important similarities and differences among the groups. The findings imply several directions for future research, and suggest that prevention policies and programs should continue to consider the role of online peers, and the Internet generally, in substance use initiation, escalation, and prevention.

Social Ecological Model of Problem Gambling: A Cross-National Survey Study of Young People in the United States, South Korea, Spain, and Finland.

Problem gambling among young people is an emerging trend globally. The online environment in particular offers various possibilities for gambling engagement. This is the first cross-national survey study using the social ecological model to analyze problem gambling, especially in the online context. The study aimed to analyze how different social ecological spheres explain problem gambling. Participants were young people aged 15-25 in the United States (n = 1212), South Korea (n = 1192), Spain (n = 1212), and Finland (n = 1200). The South Oaks Gambling Screen (SOGS) instrument measured problem gambling. The regression models analyzed problem gambling with measures of intrapersonal, interpersonal, organizational, and societal spheres. Spanish participants had the highest SOGS score for problem gambling. In all countries, the variations in problem gambling were best explained by the organizational sphere measures (26%) when compared to the intrapersonal (11%), interpersonal (5%), and societal (3%) spheres. In the full model, the organizational sphere measures had strong associations with problem gambling. These included consumer debt, online gambling community participation, online casino participation, and exposure to online pop-up advertisements. Problem gambling was also associated with conformity to group norms in the interpersonal sphere, and male gender and impulsivity in the intrapersonal sphere. Cross-national results were similar in different countries. Within the final model, gambling community participation had the strongest association with problem gambling (ß = 0.23, p < 0.001). The online context plays a major role in problem gambling behavior. The social ecological model is a useful tool for tackling problem gambling and developing preventative measures.

Young people and gambling content in social media: An experimental insight.

INTRODUCTION AND AIMS: Online gambling advertising and user-generated gambling content have increased. This study used a social psychological online experiment to analyse young people's reactions towards and self-reported interests in social media gambling messages. DESIGN AND METHODS: A vignette experiment with a two-level between-subjects factor (group condition or control condition) and three two-level within-subjects factors (expressed stance on gambling, narrative perspective and majority opinion) was conducted with two samples of young Finnish people aged 15 to 25 years (N = 1200, 50% female, mean age 21.29 years) and 15 to 30 years (N = 230, 53% female, mean age 24.35 years). Participants were asked to indicate how they would react to presented gambling messages (i.e. like or dislike the content) and how interesting would the content appear to them. In addition to experimental factors, the Attitudes Towards Gambling Scale and a global self-esteem measure were used as the independent variables. A statistical analysis included multilevel linear and logistic regressions. RESULTS: Young people preferred anti-gambling messages instead of pro-gambling messages. This effect was moderated by personal gambling attitudes as participants with highly positive gambling attitudes preferred pro-gambling content. Fact-driven messages were favoured over experience-driven messages. Positive majority opinions predicted more favourable reactions and positive interest. DISCUSSION AND CONCLUSIONS: Young people prefer anti-gambling content and factual argumentation but their online behaviour is also influenced by perceived group norms. The potential risks of online gambling promotion mainly concern young people already interested in gambling.

Impulsivity, internalizing symptoms, and online group behavior as determinants of online hate.

Online hate is widely identified as a social problem, but its social psychological dimensions are yet to be explored. We used an integrative social psychological framework for analyzing online hate offending and found that both personal risk factors and online group behavior were associated with online hate offending. Study 1, based on socio-demographically balanced survey data (N = 1200) collected from Finnish adolescents and young adults, found that impulsivity and internalizing symptoms were positively associated with online hate offending. Furthermore, social homophily was positively associated with online hate offending but only among those with average or high level of internalizing symptoms. Social identification with online communities was not associated with hate offending. In Study 2, based on a vignette experiment (N = 160), online hate offenders were more likely than others to rely on in-group stereotypes (i.e. self-stereotype) in anonymous online interaction and, as a consequence, follow perceived group norms. These associations were found only when a shared group identity was primed. We conclude that both personal risk factors and group behavior are related to online hate but they have different implications for reducing hateful communication in social media.

The Role of Perceived Loneliness in Youth Addictive Behaviors: Cross-National Survey Study.

BACKGROUND: In the ever-growing and technologically advancing world, an increasing amount of social interaction takes place through the Web. With this change, loneliness is becoming an unprecedented societal issue, making youth more susceptible to various physical and mental health problems. This societal change also influences the dynamics of addiction. OBJECTIVE: Employing the cognitive discrepancy loneliness model, this study aimed to provide a social psychological perspective on youth addictions. METHODS: A comprehensive survey was used to collect data from American (N=1212; mean 20.05, SD 3.19; 608/1212, 50.17% women), South Korean (N=1192; mean 20.61, SD 3.24; 601/1192, 50.42% women), and Finnish (N=1200; mean 21.29, SD 2.85; 600/1200, 50.00% women) youths aged 15 to 25 years. Perceived loneliness was assessed with the 3-item Loneliness Scale. A total of 3 addictive behaviors were measured, including excessive alcohol use, compulsive internet use, and problem gambling. A total of 2 separate models using linear regression analyses were estimated for each country to examine the association between perceived loneliness and addiction. RESULTS: Loneliness was significantly related to only compulsive internet use among the youth in all 3 countries (P<.001 in the United States, South Korea, and Finland). In the South Korean sample, the association remained significant with excessive alcohol use (P<.001) and problem gambling (P<.001), even after controlling for potentially confounding psychological variables. CONCLUSIONS: The findings reveal existing differences between youths who spend excessive amounts of time online and those who engage in other types of addictive behaviors. Experiencing loneliness is consistently linked to compulsive internet use across countries, although different underlying factors may explain other forms of addiction. These findings provide a deeper understanding in the mechanisms of youth addiction and can help improve prevention and intervention work, especially in terms of compulsive internet use.
