BACKGROUND: The Internet may serve as a suitable environment for discriminated adolescents as they may consider the online space as the place where they have possibility to build social ties they are missing in their offline life or manage their self-presentation. Therefore, our aim was to explore the association between different types of discrimination by peers (because of gender, physical appearance, culture/skin color/language, unfavorable family situation) and excessive Internet use (EIU), and whether gender moderates this association. METHODS: We used data from a representative sample of 6,462 Slovak adolescents (mean age: 13.00, 49.6% boys) from the HBSC study conducted in 2018. Data were collected through online self-reported questionnaires. We assessed the association between various types of discrimination by peers and EIU using linear regression, and the role of gender as potential moderator. RESULTS: Discrimination because of physical appearance was most prevalent (18.0%). Adolescents exposed to discrimination by peers reported higher levels of EIU. We found an interaction of gender on the association of discrimination because unfavorable family situation with EIU. Boys who experienced this type of discrimination were at higher risk of EIU compared to girls. CONCLUSION: Discriminated adolescents are more likely to use the Internet excessively, with some associations being stronger for boys than for girls. Prevention strategies focused on raising adolescent awareness of the risks and benefits of the Internet should target discriminated adolescents, especially boys, as they seem to be the vulnerable group.

OBJECTIVES: Adolescents who deal with more emotional problems have been found to seek escape online, and struggle with excessive internet use (EIU). Poor social relationships have been linked with emotional problems. The current study investigated positive family and school relationships as protective factors against emotional problems and a preference for online social interaction (POSI), both specified as mediators of the association of family and school relationships with EIU. Cross-cultural differences in the model were tested. METHODS: A multi-group SEM was tested on representative samples of 4104 adolescents (Mage = 14.40 years, SD = 1.65, range 12-17, 50% female) from four European countries from Southern, Northern, Central, and Eastern Europe (Italy, Norway, Czech Republic, and Serbia, respectively). RESULTS: Results suggested consistent associations across countries. Positive family relationships and positive school relationships were associated with lower EIU, with 63-64% of the effect of family, and 91-93% of the effect of school relationships mediated by emotional problems and POSI. CONCLUSIONS: Positive family and school relationships protect adolescents against excessive internet usage, regardless of culture and indirectly-through emotional problems and POSI.

This study examined the relationship between Excessive Internet Use (EIU) in adolescents and their family environment, namely the family type, the family economic status, the effect of parental care, the level of parental control, the amount of parental monitoring, the quality of communication, and the time spent together. The study was based on data from an international survey, Health Behaviour in School Aged Children (HBSC), conducted in Slovakia. The sample representative for adolescents included 2547 participants (51% boys) aged 13-15. Multiple-step linear regression revealed that higher parental care and parental monitoring predicted lower EIU, while higher parental overprotection and lower socioeconomic status predicted higher EIU. The results suggest that both so-called optimal parenting (i.e., the balance of emotional warmth and protection) and the adolescent's autonomy lower the risk of EIU. Family factors explained about 14% of the variance, which suggests that aside from personal, cognitive and affective factors, a close social environment also plays an important role in adolescence EIU.

OBJECTIVES: Excessive internet use (EIU) has been studied predominantly within the context of individual risk factors. Less attention has been paid to social factors, especially in a fashion complex enough to include the multiple domains of adolescent socialization. This study examined the relationship between EIU and constraints within family, school, peer groups, and neighbourhoods, while controlling for emotional and behavioural difficulties. METHODS: This study was based on survey data from the Health Behaviour in School-aged Children study, which was conducted in Slovakia in 2018. The sample of representative adolescents totalled 8400 (mean age: 13.44 years; SDage = 1.33; 50.9% boys). RESULTS: Multiple-step linear regression revealed that, after controlling for sociodemographic factors and emotional and behavioural difficulties, peer problems had the least effect, while the constraints related to family and neighbourhood stood out as especially problematic. Combined variables explained 20% variance of EIU. CONCLUSIONS: Social constraints proved to be important factors in adolescent EIU. The important role of a problematic neighbourhood is a novel finding and suggests that it should be targeted in prevention.

Youth subculture affiliation (SA) appears to be an important risk factor with regard to adolescents' problem behavior. Excessive Internet use (EIU) has emerged as a new type of problem behavior; however, it has not yet been studied in adolescents affiliated with youth subcultures. Thus, the aim of this study was to assess the association between SA and EIU and to explore the role of selected protective factors. We used data from the Health Behaviour in School-aged Children (HBSC) study conducted in 2014 in Slovakia. The final sample for this study comprised 532 adolescents (mean age: 15.4; 49.6% boys). Hierarchical linear regression analysis was conducted to examine the associations of EIU with SA. Adolescents with SA were more likely to report EIU. Adjustment for protective factors decreased the association between EIU and SA. From all tested interactions, only the interaction of SA with family support was found to be significant. The relationship between family support and EIU was mediated via Monitoring by the mother only in adolescents without SA. Our findings imply that the risk of EIU is higher in adolescents with SA. There was a difference in how protective factors worked in adolescents with and without SA.

Excessive Internet use is becoming a rapidly increasing problem in today's society. Our aim was to assess the association between socioeconomic status (SES) of the family and excessive Internet use (EIU), and whether life satisfaction mediates this association. We analyzed data from a representative sample of 2844 Slovak adolescents (mean age 14.34, 50.5% boys) from the 2014 Health Behavior in School aged Children (HBSC) study, based on self-report questionnaires. We assessed the association of SES, measured by several indicators, such as perceived family wealth, parental education, and (un)employment, and adolescent EIU using linear regression, adding life satisfaction as a mediator. Adolescents whose father was unemployed and whose perceived family wealth was low tended to score higher on EIU. Neither gender nor age affected this relationship. Life satisfaction mediated a part of the association between SES and EIU in the case of low perceived family wealth and father's (un)employment. Adolescents with a low SES are more likely to become excessive Internet users, and life satisfaction mediates this association. Prevention of EIU among adolescents should be targeted at those with low SES, with life satisfaction being the topic to address.

BACKGROUND: Both eating disorders and excessive internet use represent significant health issues for contemporary adolescents. Yet, the link between them has seldom been investigated. We aim to study this association through their common underlying psychological factors: internalising problems and externalising problems. METHODS: A representative sample of 7,083 adolescents (Mage = 13.48 years; SDage = 1.32; 50.3% girls) from Slovakia was obtained from the Health Behaviour in School-aged Children (HBSC) project in 2018. Study variables included the Excessive Internet Use Scale (EIU) and the Strength and Difficulties Questionnaire (SDQ). Eating disorders symptoms (EDS) were assessed by SCOFF and selected items from the Eating Disorder Screen for Primary Care (ESP). Data were analysed separately for boys and girls with Structural Equation Modelling. RESULTS: There was a partial correlation between EDS and EIU (r = 0.36 for boys and r = 0.29 for girls) after controlling for the internalising and externalising of problems. Internalising and externalising problems were positively associated with EDS, while EIU was only associated with externalising problems. The results were comparable for both genders. CONCLUSION: The study provides evidence that, during adolescence, EDS and EIU are related and have a tendency to occur together. Also, they are related even when controlled for their shared underlying psychological factors, namely the emotional and attentional/behavioural difficulties.

The study found that, in adolescents, eating disorders symptoms are associated with excessive internet use even when controlled for their shared psychological factors. Self-control issues were associated with both the eating disorder symptoms and excessive internet use, while emotional issues were only associated with the eating disorder symptoms. The strength of the relationship was similar for boys and girls, even though the prevalence of eating disorders symptoms was double in girls.

Background and aims Young people's involvement in online gaming and the use of social media are increasing rapidly, resulting in a high number of excessive Internet users in recent years. The objective of this paper is to analyze the situation of excessive Internet use among adolescents in the Czech Republic and to reveal determinants of excessive use of social media and excessive online gaming. Methods Data from secondary school students (N = 4,887) were collected within the 2015 European School Survey Project on Alcohol and Other Drugs. Logistic regression models were constructed to describe the individual and familial discriminative factors and the impact of the health risk behavior of (a) excessive users of social media and (b) excessive players of online games. Results The models confirmed important gender-specific distinctions - while girls are more prone to online communication and social media use, online gaming is far more prevalent among boys. The analysis did not indicate an influence of family composition on both the excessive use of social media and on excessive online gaming, and only marginal effects for the type of school attended. We found a connection between the excessive use of social media and binge drinking and an inverse relation between excessive online gaming and daily smoking. Discussion and conclusion The non-existence of significant associations between family environment and excessive Internet use confirmed the general, widespread of this phenomenon across the social and economic strata of the teenage population, indicating a need for further studies on the topic.

OBJECTIVES: This study investigated the differences between non-excessive, moderately excessive, and highly excessive internet use among adolescents. These differences were explored in terms of personal characteristics, psychological difficulties, environmental factors, and manner of internet use. METHODS: A representative sample was investigated, consisting of 18,709 adolescents aged 11-16 and their parents, from 25 European countries. Excessive internet use was measured using a five item scale covering following factors: salience, conflict, tolerance, withdrawal symptoms, and relapse and reinstatement. The main data analysis utilised multinomial and binary logistic regression models. RESULTS: The vast majority of respondents reported no signs of excessive internet use. Moderately excessive users (4.4%) reported higher emotional and behavioural difficulties, but also more sophisticated digital skills and a broader range of online activities. The highly excessive users (1.4%) differed from the non-excessive and moderately excessive users in their preference for online games and in having more difficulties with self-control. CONCLUSIONS: Adolescents who struggle with attention and self-control and who are inclined toward online gaming may be especially vulnerable to the otherwise uncommon phenomenon of excessive internet use.

OBJECTIVES: The aim of this study was to evaluate the relationship between internet addiction, substance use and alexithymia among students of education faculty and medical faculty. METHODS: This cross-sectional analytical study included 1,257 faculty students aged 18 and over, studying at Meram Medical Faculty and Ahmet Keleşoğlu Faculty of Education. Young's Internet Addiction Scale, Toronto Alexithymia Scale, Fagerström Tobacco Addiction Test and CAGE alcohol use tests were applied to collect data. RESULTS: The mean age of the participants was 21.12 ± 1.96 years, 71% (n = 893) of them were females and 29% (n = 364) were males, 37.9% (n = 477) were training at medical faculty, 62.1% (n = 780) were training at the faculty of education. Of the students, 1.5% were internet addicts, 15.3% were possible addicts, and 22.8% had alexithymia. Internet addiction was higher in those with higher alexithymia scores (p < 0.001). Internet addiction was significantly higher in male students, the third grade, ones with lower academic success, students who work their lessons less than 2 hours a week. Internet addiction was also significantly higher in smokers and alcohol users (p < 0.001). While there was a low negative correlation between the first internet using age and internet addiction (p < 0.001), there was a moderately significant positive correlation between spending uninterrupted time on the internet and internet addiction (p < 0.001). CONCLUSION: In this study, it was determined that the teacher and doctor candidates, who are studying at the faculties of education and medicine, were at risk of internet addiction. A teacher or a doctor who cannot develop social skills due to excessive internet use will not be a good model to communicate correctly with the target population.
