いじめ被害とストレス反応，仲間関係，学校適応感との関連

Abstract: Background: Cyberbullying describes bullying using mobile phones and the internet. Most previous studies have focused on the prevalence of text message and email bullying. Methods: Two surveys with pupils aged 11–16 years: (1) 92 pupils from 14 schools, supplemented by focus groups; (2) 533 pupils from 5 schools, to assess the generalisability of findings from the first study, and investigate relationships of cyberbullying to general internet use. Both studies differentiated cyberbullying inside and outside of school, and 7 media of cyberbullying. Results: Both studies found cyberbullying less frequent than traditional bullying, but appreciable, and reported more outside of school than inside. Phone call and text message bullying were most prevalent, with instant messaging bullying in the second study; their impact was perceived as comparable to traditional bullying. Mobile phone/video clip bullying, while rarer, was perceived to have more negative impact. Age and gender differences varied between the two studies. Study 1 found that most cyberbullying was done by one or a few students, usually from the same year group. It often just lasted about a week, but sometimes much longer. The second study found that being a cybervictim, but not a cyberbully, correlated with internet use; many cybervictims were traditional ‘bully-victims’. Pupils recommended blocking/avoiding messages, and telling someone, as the best coping strategies; but many cybervictims had told nobody about it. Conclusions: Cyberbullying is an important new kind of bullying, with some different characteristics from traditional bullying. Much happens outside school. Implications for research and practical action are discussed. Keywords: Bullying, victim, cyber, mobile phone, internet, adolescence, aggression, computers.

Abstract: Cyberbullying has recently emerged as a new form of bullying and harassment. 360 adolescents (12–20 years), were surveyed to examine the nature and extent of cyberbullying in Swedish schools. Four categories of cyberbullying (by text message, email, phone call and picture/video clip) were examined in relation to age and gender, perceived impact, telling others, and perception of adults becoming aware of such bullying. There was a significant incidence of cyberbullying in lower secondary schools, less in sixth-form colleges. Gender differences were few. The impact of cyberbullying was perceived as highly negative for picture/video clip bullying. Cybervictims most often chose to either tell their friends or no one at all about the cyberbullying, so adults may not be aware of cyberbullying, and (apart from picture/video clip bullying) this is how it was perceived by pupils. Findings are discussed in relation to similarities and differences between cyberbullying and the more traditional forms of bullying.

Abstract: This research addressed 2 limitations of past research on peer victimization: the tendency to study boys only and the tendency to focus on forms of peer maltreatment that are common in boys' peer groups (victimization through overt aggression) but occur much less frequently in girls' peer groups Peer- and self-report instruments were used to assess a relational form of victimization in addition to the overt form that has been the focus of past research Results showed that girls were more relationally victimized, whereas boys were more overtly victimized Both forms of victimization were shown to predict concurrent sociopsychological adjustment problems significantly (eg, peer rejection, loneliness) beyond aggression Victims identified through a combination of self- and peer-reports were particularly maladjusted

Abstract: A number of 14-16 year old Finnish adolescents taking part in the School Health Promotion Study (n=8787 in 1995, n=17643 in 1997) were surveyed about bullying and victimization in relation to psychosomatic symptoms, depression, anxiety, eating disorders and substance use. A total of 9 per cent of girls and 17 per cent of boys were involved in bullying on a weekly basis. Anxiety, depression and psychosomatic symptoms were most frequent among bully-victims and equally common among bullies and victims. Frequent excessive drinking and use of any other substance were most common among bullies and thereafter among bully-victims. Among girls, eating disorders were associated with involvement in bullying in any role, among boys with being bully-victims. Bullying should be seen as an indicator of risk of various mental disorders in adolescence.

Abstract: The increasing availability of Internet and cell phones has provided new avenues through which adolescents can bully. Electronic bullying is a new form of bullying that may threaten adolescent social and emotional development. In this study the relation between involvement in electronic and traditional bullying was examined. Eighty-four adolescents completed questionnaires regarding their involvement in traditional and electronic bullying. Results show that students' roles in traditional bullying predicted the same role in electronic bullying. Also, being a victim of bullying on the Internet or via text messages was related to being a bully at school. Traditional victims were not found to be electronic bullies. Perceptions of the effects of and motivations for electronic bullying are discussed.
