Cyberbullying is defined as an intentional online act via electronic media, to harm, embarrass and/or humiliate another person. As adolescents with attention deficit hyperactivity disorder (ADHD) are at a higher risk in being involved in bullying behaviour as perpetrators or victims, the main purpose of this study is to examine the prevalence of their cyber experience and its impact on loneliness, perceived self-efficacy and social support. The study population included 140 adolescent students with ADHD taking part in general classes and 332 students without disabilities, all of whom completed four self-report questionnaires (cyberbullying, perceived feelings of loneliness, self-efficacy and social support). The findings show no significant differences between students with or without ADHD regarding the time spent on the net and their perceived usage expertise. Most participants with ADHD were familiar with the internet and spent a similar amount of time surfing as the adolescents without ADHD. Results revealed significant differences between the student groups (ADHD/Non-ADHD) and some of the social-emotional measures: students with ADHD who were cybervictims and students with ADHD who were cyberwitnesses reported on greater feelings of emotional loneliness and a lower belief in their social self-efficacy than the non-ADHD students. Furthermore, ADHD student cyberwitnesses also reported on feelings of greater social loneliness. Findings revealed that girls were significantly more often cybervictims than boys. However, boys reported on significantly more involvement as cyberperpetrators than girls.

Cyberbullying refers to a negative activity aimed at deliberate and repeated harm through the use of a variety of electronic media. This study examined the Internet behavior patterns and gender differences among students with learning disabilities who attended general education and special education classes, their involvement in cyberbullying, and the relationships among being cyberbullied, their responses, and their coping strategies. The sample consisted of 149 students with learning disabilities (LD) attending general education classes, 116 students with comorbid LD attending special education classes, and 242 typically achieving students. All the students, studying in middle and high schools, completed a self-report cyberbullying questionnaire. Findings indicate that although no significant differences emerged in the amount of surfing hours and students’ expertise in the use of the Internet, students attending special education classes are more likely to be cybervictims and cyberperpetrators; girls are more likely to be cybervictims, whereas boys are more likely to be cyberperpetrators. These results contribute to our understanding of students’ involvement in cyberbullying and can serve as a basis for developing preventive programs as well as intervention programs for students and for educational school teams.

The focus of this paper is the design of technology products and services for disabled students in higher education. It analyses the perspectives of disabled students studying in the US, the UK, Germany, Israel and Canada, regarding their experiences of using technologies to support their learning. The students shared how the functionality of the technologies supported them to study and enabled them to achieve their academic potential. Despite these positive outcomes, the students also reported difficulties associated with: i) the design of the technologies, ii) a lack of technology know-how and iii) a lack of social capital. When identifying potential solutions to these difficulties the disabled students imagined both preferable and possible futures where faculty, higher education institutions, researchers and technology companies are challenged to push the boundaries of their current design practices.

The current study examined whether perceived social support mediated the effects of loneliness and self-efficacy on well-being among students with or without a learning disability (LD). Participants included 834 elementary, middle, and high school students from Israel (29.6% students with LDs) who completed self-report questionnaires. The results of structural equation modeling indicate that social support mediates the indirect effects of age, gender, loneliness and self-efficacy on well-being. In addition, the results show differences between groups, as non-LD girls noted a higher self-efficacy and well-being than boys, and well-being had indirect effects in the non-LD group than in the LD group. These results indicate students with LDs have a unique social-emotional profile that affects their well-being. The study highlights the importance of enhancing self-efficacy and reducing loneliness in order to increase social support, thus predicting positive well-being. Effective and practical educational programs are needed for both groups across age and gender.

This study examined the relationship between social-environmental influences and body image perception. Specifically, the study explored the perceived body appearance among young and older students attending higher education, and their eating experiences, as related to four main social-environmental circles: family, friends, work colleagues, and media. The present study interviewed 30 students (14 men and 16 women) ages 20–40. The findings show that most of the participants were concerned about their appearance, reported on various eating habits rooted on family tradition. Findings revealed differences among gender and age groups regarding, especially regarding sport and dissatisfaction with their own perceived appearance. Although more women reported on healthy eating habits and doing sport, they reported higher dissatisfaction with their body appearance. It was found that in both groups, family habits and their parents’ remarks about bodies had an ongoing effect and significant influence on their body self-perceptions. Further health promotion should be directed in particular to individuals with a perceived negative body image, in order to enhance positive body self-perception, implementing heathy eating habits and engaging higher commitment to sport.
