This study examined the relationship between being members of social network sites (SNS) and the reasons for their use among individuals who are between 20-66 years of age. Social networking status and virtual loneliness are examined according to reasons for using SNS of participants. Researcher did a web-based questionnaire upon Facebook (FB) and reached a volunteer group of FB users and gave Social Networking Status Scale ( SNSS) and Virtual Loneliness Scale (VELS) in order to measure participants networking status and virtual loneliness according to socio-demographical variables. SNSS, gender, and age are the strongest predictors of virtual loneliness. Also, male participants, SNSS scores are significantly higher than female participants which indicates that male participants are more dependent on SNS. When time spent online increases individuals get convergence to usual habits in the virtual world. Individuals SNS usage habits effects their normal lives and make them escape to the virtual world.

This paper presents an investigation that aims to: 1) explore the relations between core symptoms of adult Attention Deficit and Hyperactivity Disorder (ADHD) and several typical Internet activities, and 2) compare the predictive power of two core symptoms of ADHD- inattention and hyperactivity/impulsivity- in predicting Internet addiction. Methods: A total of 2016 Chinese college students participated in this study. The ADHD symptoms were assessed using Conners self-rating scales and DSM-5 semi-structured interviews. Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (SCID-5) was used to exclude other psychiatric disorders. Chen’s Internet addiction scale (CIAS) was used to evaluate Internet addiction. Information about Internet activities (e.g., online gaming) was collected through a self-constructed questionnaire. Results: The ratio of Internet addiction problems among individuals with ADHD symptoms is significantly higher than in ordinary individuals (48.9% vs. 14.3%). Further, each core ADHD symptom has unique relations with different types of Internet activities. Specifically, both core ADHD symptoms are negatively associated with information downloading and online learning, and positively associated with online gaming, while online shopping is only associated with hyperactivity/impulsivity. Furthermore, both core ADHD symptoms are significant predictors of Internet addiction, especially inattention. Conclusion: College students with ADHD symptoms are at a higher risk of having Internet addiction than peers without ADHD symptoms. For individuals with ADHD symptoms and excessive online gaming and/or online shopping behaviors, the probability of having Internet addiction is even higher. These findings have important implications for identifying risk factors of Internet addiction and preventing Internet addiction in Higher Education settings.

Challenges relating to misuse and abuse of the internet and other mobile devices have become sources of concern among the youth population the world-over. However, research on cyber related issues has been focused mainly on adolescents in Nigeria. This study investigates the influence of cyber bullying, cyber victimization and pathological internet use on psychological well-being among adults. Using a cross sectional research design and a multi-stage sampling technique, 280 university students were selected. A questionnaire on socio-demographic profile cyber intimidation and internet addiction was administered to the participants. Data were analyzed using descriptive statistics and t-test analysis at 0.05 level of significance. Three hypotheses were tested. The results revealed that participants who engage less in cyber bullying were not significantly different in their levels of psychological well-being when compared to their counterparts who engage more in cyber-bullying. Pathological Internet use did not significantly influence the levels of psychological well-being of cyber space addicts. The association between cyber related variables and psychological well-being is crucial for better understanding of their actual effects on human behaviour and for the purpose of designing intervention programmes.

Online trolling is online behavior in which the troll provokes, harms, and pretends to be someone else to achieve their goals. The purpose of trolls may be to harm the other person, but they can also be for entertainment purposes. Online trolling, for whatever purpose, can have significant psychological effects on individuals and people who are socially exposed. In addition, online trolling is becoming more common every day. However, there are very few studies on trolling. Therefore, the study aims to examine the mediating role of empathy in the relationship between dark triad personality traits and levels of online trolling. For this purpose, structural equation modeling and bootstrapping method was used. The participants comprised 516 (%71.6 females; %28.4 males) undergraduates. The ages of the participants ranged from 18 to 31 (X̄ = 21.09). The measures used included the Online Trolling Scale, Dirty Dozen Scale, and Toronto Empathy Questionnaire. In the study, it was found that there were significant relationships between the dark triad, online trolling, and empathy. Also, the results of the structural equation model showed that the effect of the dark triad on online trolling was mediated by empathy. This result was found to be significant with bootstrapping.

The lives and learning experiences of high school students are increasingly intertwined with online activities. With the global trend of Education 4.0, equipping students with digital skills is essential, including the capacity for online social-emotional skills. Someone with social-emotional skills knows how to turn social media into a useful tool, providing opportunities for personal development. This study focuses on developing social-emotional competence for high school students in the context of the Education 4.0 trend. The project has developed a learning program consisting of 6 common social-emotional skill themes for both virtual and real environments and implemented a test on 34 students. Using experimental evaluation methods, classroom observation, and quantitative methods were employed to assess the effectiveness of the program. The results indicate a significant improvement in students' social-emotional competence, with an average score post-experiment of 3.7397. Our experimental model also achieved 63.6% of CASEL criteria for organizing social-emotional competence. Therefore, the study has strengthened the findings and achievements in the development of social-emotional competence training in the fields of educational psychology in Vietnam.
