1 There is some consensus that bullying is aggressive behaviour which intentionally hurts or harms another person; together with repetition — it happens more than once; and a power imbalance such that it is difficult for the victim to defend him- or herself (Olweus, 1999). A succinct definition is the ‘systematic abuse of power’ (Smith & Sharp, 1994). It can occur in many contexts, in childhood and adult life (Monks et al., 2009). However, the earliest sustained work, and the largest volume of work, has concerned school bullying. Bullying can be carried out by a group, or by one stronger individual; although usually considered in the context of pupil-pupil relationships, both teacher-pupil and pupil-teacher bullying may occur. Besides physical bullying — the larger child hitting and beating up a smaller one — and verbal bullying — nasty forms of teasing and verbal abuse — there can be indirect and relational bullying. Indirect bullying refers to some kind of social manipulation using others as a means of attack instead of attacking oneself, or otherwise manipulating the social network of the class; and relational bullying to inflicting harm on peers in ways that damage peer relationships; these overlapping concepts cover spreading nasty rumours, and social exclusion. More recently cyberbullying has emerged as a major topic.

2Research on school bullying can be thought of as having gone through four waves (Smith, 2012).

 First wave: origins 1970s — 1988

3The systematic study of bullying in schools can be dated from the 1970s, mainly in Scandinavia. In 1973 Olweus published Forskning om skolmobbning, translated into English in 1978 Aggression in Schools: Bullies and Whipping Boys. Here, bullying or “mobbing” was defined in terms of physical and verbal behaviours, although Olweus explicitly rejected the “mobbing” label (which implies group bullying), since much bullying appeared to be by one person. Through the 1980s, Olweus developed a self-report questionnaire to assess bullying, an important tool in subsequent work. Also, in parallel with the first Norwegian National Anti-Bullying campaign in 1983, he developed a school-based intervention program. His evaluation of the original version of the Olweus Bullying Prevention Program (1983-1985), with reports of reductions in bullying of around 50%, encouraged researchers and inspired the next wave of research.

 Second wave: establishing a research program 1989 — mid-1990s

4From around 1989, books and journal articles started to appear; and surveys in other countries beyond Scandinavia were beginning to be carried out. Besides self-report surveys, some studies started to use peer nominations methodology. Also, some intervention campaigns took place in other countries, partly inspired by the Norwegian campaign.

5An important change in this period was a broadening of researcher’s definition of bullying, to include indirect and relational bullying (such as rumour spreading, social exclusion); this followed the similar broadening of understanding of “aggression”, following the work of Bjorkqvist and colleagues in Finland, and Crick and colleagues in the USA. Also, work on bullying was becoming more international. Contacts were taking place with researchers in North America, and towards the end of this period, with researchers in Japan. In fact, studies on ijime (the term closest to bullying) dated back at least to the 1980s, but this separate research tradition only made substantial contact with the western research tradition following a Monbusho/UNESCO study in the later 1990s (see Smith et al., 1999).

 Third wave: an established international research program mid-1990s — 2004

6During this period, research on “traditional” bullying became an important international research program. Many more publications appeared, and research on bullying featured substantially in European and international conferences. Surveys, and interventions, took place in many countries (see 21 country reports in Smith et al., 1999; and 11 country reports on interventions in Smith, Pepler and Rigby, 2004). A notable methodological step was the introduction of participant roles in bullying, from Salmivalli’s work in Finland (Salmivalli et al., 1996). Researchers in the USA substantially developed research on victimization and bullying during this period (Espelage & Swearer, 2004), and important work was also being undertaken in Australia and New Zealand (Rigby, 2002).

 Fourth wave: cyberbullying 2004-

7Over the last decade, cyberbullying has become a significant aspect to be taken account of (Tokunaga, 2010; Smith, 2012). This started off as text message and email bullying, which increased through the mid-2000s (Rivers & Noret, 2010); but since then the development of smart phones, and greatly increased use social networking sites, have offered many new tools for those wishing to hurt others. Broadly speaking, cyberbullying now takes up an appreciable fraction of total bullying in young people (around one-third). However work on “traditional” or offline bullying has continued to develop (Jimerson, Swearer & Espelage, 2010).


8Compared to traditional bullying, cyberbullying is much more likely to be perpetrated and experienced outside of school; but is still often between class- or school-mates. Cyberbullying differs from traditional bullying in a variety of ways. Smith (2012) described seven features: (1) it depends on some degree of technological expertise; (2) it is primarily indirect rather than face-to-face, and thus may be anonymous; (3) relatedly, the perpetrator does not usually see the victim’s reaction, at least in the short term; (4) the variety of bystander roles in cyberbullying is more complex than in most traditional bullying (the bystander may be with the perpetrator when an act is sent or posted; with the victim when it is received; or with neither, when receiving the message or visiting the relevant Internet site); (5) one motive for traditional bullying is thought to be the status gained by showing (abusive) power over others, in front of witnesses, but the perpetrator will often lack this in cyberbullying; (6) the breadth of the potential audience is increased, as cyberbullying can reach particularly large audiences in a peer group compared with the small groups that are the usual audience in traditional bullying; (7) it is difficult to escape from cyberbullying (there is “no safe haven”), as the victim may be sent messages to their mobile or computer, or access nasty website comments, wherever they are.

9By extending the definition from traditional bullying, cyberbullying has been defined as “an aggressive act or behaviour that is carried out using electronic means by a group or an individual repeatedly and over time against a victim who cannot easily defend him or herself” (Smith et al., 2008). However the criteria of repetition, and power imbalance, while relatively clear for traditional bullying, have more difficulties in application to cyberbullying.

10First, the idea of repetition within cyberbullying is not as straightforward; one cyberbullying act may readily “snowball” out of the initial control of the bully, due to the technology used. An example is a picture that is sent (or uploaded onto the Internet), that at a later stage is distributed by other people (not the initial perpetrator). Thus a single act by one perpetrator may be repeated many times by others, and experienced many times by the victim. If the repetition is not carried out by the perpetrator, is this still cyberbullying?

11The second definitional issue is that of power imbalance. In traditional bullying this might refer to physical or psychological weakness, or it might refer to numbers of aggressors, or popularity/rejection in a peer group context. Such forms of power imbalance within the cyberbullying context are not so clear. Vandebosch and Van Cleemput (2008) argued that a greater knowledge of ICT’s may contribute to a power imbalance; they found that pupils with more advanced Internet skills were more likely to have experience with deviant Internet and mobile phone activities. Ybarra and Mitchell (2004) found that cyberbullies do rate themselves as Internet experts to a higher degree compared to those who do not cyberbully others. However, in much of the text message and website bullying experienced by pupils of school age, technological skill is arguably a minor factor. Vandebosch and Van Cleemput (2008) also argued that anonymity can contribute to a power imbalance. Often the victim does not know who the person bullying him/her is. It is more difficult to respond effectively if you do not know the identity of the perpetrator. Conversely, if a victim does know the perpetrator, then the more conventional criteria of physical/psychological strength and peer group popularity may come back into play (i.e., a victim may be fearful of retaliating against a popular and stronger pupil who may take further revenge offline).

12In summary, defining cyberbullying may not be as clear cut as defining traditional bullying, due to difficulties in the criteria of repetition and power imbalance. These issues, and the extent to which cyberbullying can usefully be distinguished from a broader concept of cyber aggression or cyber victimization, are being debated.

 Bias or identity-based bullying

13The terms bias bullying, identity-based bullying or prejudice driven bullying refer to bullying on the basis of group rather than individual characteristics, and include racial harassment, faith-based bullying, sexual harassment, and homophobic bullying. Racist bullying is a worrying feature in some schools, although the extent varies between cultures (Sawyer, Bradshaw & O’Brennan, 2008). There has been considerable research on homophobic bullying (Rivers, 2011). In secondary schools, children may be teased about their sexual orientation, and even physically assaulted or ridiculed about this by other pupils or teachers. In Great Britain, a Stonewall report (Stonewall, 2007) found that 65% of lesbian/gay/bisexual (LGB) students reported homophobic victimisation; this was most frequent from boys in the same year group c. 80% of cases) but not infrequently from girls (c. 50%). Explicit school rules regarding the issue was associated with lower incidence. In the US, Birkett, Espelage, and Koenig (2009) found that positive school climate can lessen negative outcomes for LGB students.

14Another risk factor is having a disability or special educational needs. Children with special needs are two to three times more at risk of being bullied; they are also more at risk of taking part in bullying others (Mishna, 2003). They may have particular characteristics which make them an obvious “target”; in mainstream settings are less well integrated socially and lack the protection against bullying which friendship gives; and, those with behavioural problems may act out in an aggressive way and become “provocative victims”. Adolescents with autism spectrum disorders have been found to be at higher victimisation risk, especially when they misinterpret social situations (Roekel, Scholte & Didden, 2009).

 Measurement of bullying

15Large-scale surveys have used questionnaires. The Olweus anonymous self-report questionnaire is the most widely used internationally; it incorporates a standard definition of bullying (Solberg & Olweus, 2003). Questionnaires have obvious advantages in terms of getting information from many informants, quickly and easily. Another well-used methodology is nominations; here, an informant is asked to nominate self or others (e.g. classmates) for involvement in roles such as bully, or victim. A development of this technique allows differentiation of participant roles such as ringleader bully, follower, reinforcer, outsider and defender, as well as victim (Salmivalli et al., 1996); and more recently, asking for who is involved in dyadic relationships in all the main participant roles (Huitsing & Veenstra, 2012).

16Many other methods can provide useful information. These include nominations; interviews and focus groups; diaries, blogs, and drawings; and observations. The informant is often the pupil him- or herself; or a peer — usually someone in the same class, or year group, at school. Self-reports by pupils have been widely used in questionnaires, and pupil reports in peer nomination procedures. The informant can also be an adult at school — usually the class teacher, or perhaps a pastoral care teacher, school nurse or counsellor; and a family member — usually a parent or carer, or perhaps a sibling or other relative. Adult (teacher and parent) reports might have limited value for pupil-pupil bullying, as adults are often only aware of a fraction of what is going on in the peer group.

 Prevalence of bullying

17The actual prevalence figures reported in surveys vary very greatly. Considering questionnaire surveys, prevalence rates will be influenced by: what time span is being asked about (e.g. last month, last term, last year, ever at school); what frequency is regarded as bullying (e.g. once/twice a term; once a month, once a week or more); what definition is used (e.g. whether it includes indirect as well as direct forms, and cyberbullying). All these issues make it often difficult to compare across studies; it also means that absolute incidence figures are rather meaningless, in isolation.

18Cook et al. (2010) examined quantitative studies of school bullying published from 1999 to 2006. A search revealed 82 studies that met criteria for a meta-analysis. Of these, 45 were in Europe, 21 in the United States, and 16 in other locations. The majority, 61 studies, used self-report data, 13 peer report, and 8 teacher or parent report. The authors calculated average prevalence rates of around 20% for bullies, 23% for victims, and 8% for bully/victims. There was a high variability in figures across studies, but overall these are quite high figures; this is probably because bullying that only happened “once or twice” in a time referent period was included in a number of studies. Peer nomination methods produced lower bully and victim rates than either self or teacher/parent report (but no difference for bully/victim rates).

19Two large-scale sources of prevalence data, gathered systematically across countries, come from the World Health Organisation surveys on Health Behaviour in School-aged Children (HBSC); and the EU Kids Online project.

20The HBSC surveys collect data from 11-, 13- and 15- years olds from nationally representative samples, every four years, starting in 1993/1994; there is a minimum of 1, 500 respondents per year group, in each participating country. These are classroom-based, anonymous self-report questionnaire surveys. The reports on bullying are based on a single victim item and a single bully item, adapted from the Olweus questionnaire, which asks about experiences over the past couple of months, with five response options. Victim or bully rates were calculated from, “at least two or three times in the past couple of months” or more (so, ignoring “it only happened once or twice”).

21Craig et al. (2009) provide findings from the 2005/2006 survey. This data set is from 40 countries, mostly European, but also including the United States, Canada, Russian Federation, and Ukraine. The rates for bullying others average out at 10.7%, and for being bullied (victims) at 12.6%, with 3.6% scoring as bully/victims. Currie et al. (2012) provide data from the 2009/2010 HBSC survey. This data set is from 38 countries, again mostly European, but also including the United States, Canada, Russian Federation, Armenia and Ukraine. The rates for bullying others average out at 10.3%, and for being bullied (victims) at 11.3% (there was no separate category for bully/victims). It can be seen that there is a slight decrease in figures between the two surveys. It is also noticeable that these figures are less than half the level from the Cook et al. (2010) review.

22Livingstone, Haddon, Görzig and Ólafsson (2011) report findings on traditional bullying and cyberbullying from 25 European countries, from the EU Kids Online survey on Internet use, risks and safety, carried out in spring/summer 2010. The samples were based on random stratified sampling of some 1000 children, aged 9 to 16 years, in each country, with a total sample of 25,142. Self-report survey questionnaires were given face-to-face. A section on bullying explained that this could be face-to-face; or by mobile phone calls or texts; or on the Internet. Then the child or young person was asked whether someone had acted in this hurtful or nasty way to them in the past 12 months, for these three types of activities. Following that, they were asked if they themselves had acted in a hurtful or nasty way to others in the last year. Responses were scored as more than once a week, once or twice a month, less often than that, or never.

23Across the European countries, 19% of 9-16 year olds said that something nasty had happened to them in the past 12 months. However only 5% said this had happened more than once a week, and another 4% once or twice a month, with 10% responding that it was less often. Victim rates were slightly higher in girls, and increased slightly with age. Face-to-face or offline bullying experiences were most frequent at 13%, on the Internet by 6% (this was mostly on a social networking site or by instant messaging), and by mobile phone by 3%.

24Perpetrator or bullying rates averaged 12% across the whole sample. Only 2% said this had happened more than once a week, and another 3% once or twice a month, with 7% responding that it was less often. There was little gender difference (boys slightly higher at 3% in the more than once a week category), and bully rates increased somewhat with age. Face-to-face or offline bullying of others was most frequent at 10%, on the Internet by 3% (this was mostly on a social networking site or by instant messaging), and by mobile phone by 2%.

25If one disregards experiences that were less frequent than once or twice a month, then bully prevalence is 5% and victim prevalence is 9%. This is lower than the HBSC findings with a corresponding frequency cutoff, and much lower than the figures from the Cook et al. meta-analysis. The HBSC figures are about 10% and 11% respectively, so the main discrepancy is the lower prevalence of bullying others in the EU Kids Online findings. This is unexplained, although one possible explanation could be a greater unwillingness to admit to bullying others in a face-to-face interview compared to an anonymous class-based questionnaire.

 Changes in prevalence rates over time

26The two HBSC surveys above show some decrease in bully and victim prevalence rates over time. This appears to be a general trend. Rigby and Smith (2011) reported on various sources of data over the period 1990 to 2009, and concluded that a modest but significant decrease in bullying has been reported in many countries. However, there are some indications that cyber bullying, as opposed to traditional bullying, has increased, at least during some of this period.

 Age and gender trends in bullying

27Questionnaire surveys generally show that self-reports of being bullied decline rather steadily through adolescence; self-reports of bullying others do not show this decline (Smith, Madsen & Moody, 1999). There tends to be some shift with age away from physical bullying and toward indirect and relational bullying. Cyberbullying has a somewhat later age peak, at mid-adolescence, than is found for traditional bullying (Eslea & Rees, 2001; Tokunaga, 2010).

28In traditional bullying, boys are more numerous in the bully category, but the sexes are more equal in the victim category. Boys practice/experience more physical bullying, girls more indirect and relational bullying. Girls’ bullying (compared to boys’) is more bound up with friendships, feuds and exclusion (Besag, 2006). In cyberbullying, gender differences vary considerably between studies, but relatively, girls may be more involved in cyberbullying and victimisation.

 Risk factors in victimisation

29Some risk factors are at the individual level, including genetic factors. In England and Wales the Environmental Risk (E-Risk) Study of over 1000 twin pairs (Ball et al., 2008) found strong genetic influence on children’s victimisation status at 9-10 years (MZ &#91identical&#93 twins had more similar victimisation experiences than DZ twins), and also on bullying behaviour. These genetic factors may operate through various mechanisms including personality disposition, emotion regulation, or social cognition, many identified as individual risk factors in bullying (Farrington & Baldry, 2010). For example boys who bully have been found to have low affective empathy (sharing others’ emotions), although not low cognitive empathy (understanding others emotions) (Jolliffe & Farrington, 2011). In secondary school pupils, moral disengagement, together with expectations of positive outcomes from harmful behaviour, have been found to facilitate both traditional and cyber aggression to peers (Pornari & Wood, 2009). Although some bullying children may lack social skills, ringleader bullies especially may have good “theory of mind” abilities (understanding of others’ mental states) and be skilled social manipulators (Sutton, Smith & Swettenham, 1999).

30In terms of the school peer group, risk factors comprise having few friends, especially friends who can be trusted or who are not themselves of low status; and sociometric rejection (dislike by peers). One hypothesis is that some children who bully are driven by a desire for dominant status in the peer group (Salmivalli, 2010). This highlights the importance of bystanders, with evidence that children with both high empathy and high peer group status, can be the most effective defenders (Nickerson, Mele & Princiotta, 2008; Caravita, DiBlasio & Salmivalli, 2009). In-group attitudes within the class or peer group may be influential (Nesdale et al., 2008), and can lead to ostracism of those perceived as different (Dixon, 2007), but there is little evidence for the scapegoating theory (since many classes have no victims, and many have several) (Mahdavi & Smith, 2007).

31In terms of family background factors, there is some evidence that victims may come from over-protective or enmeshed families. Children who bully others may come from families lacking warmth, in which violence is common, and discipline inconsistent. Children who are both bullies and victims, or are aggressive victims, may come from particularly troubled or abusive families (Nickerson, Mele & Osborne-Oliver, 2010).

32The E-Risk study found that school factors were mainly associated with victim risk, family factors with bully risk, and neighbourhood factors with risk of bully/victim status (Bowes et al., 2009); and that maternal and sibling warmth and positive home atmosphere contribute to resilience in coping with victimisation (this twin study demonstrating that this is an environmental, not genetic, effect) (Bowes et al., 2010). School factors may operate through school climate, school policies and anti-bullying strategies; with some research highlighting the role of pupil relationships with teachers (Troop-Gordon & Quenelle, 2010).

 Consequences of involvement in bullying

33A meta-analysis of 11 studies found that between 7 and 16 years, bullies, bully-victims, and victims, all had significantly higher risk of psychosomatic problems compared to uninvolved peers (Gini & Pozzoli, 2009). Another meta-analysis (Ttofi et al., 2011) found that victimization was a significant risk factor for later depression, even after controlling for up to 20 other risk factors. Rothon et al. (2011) found a significant association of victimisation with poorer academic achievement. A narrative review confirms that being the victim of bullying contributes independently to children’s mental health problems, and can have long-lasting effects (Arseneault, Bowes & Shakoor, 2010). A longitudinal analysis of in England found that being a victim of chronic or severe bullying at 8 or 10 years was associated with substantially greater odds of psychotic symptoms at age 12, even controlling for other prior psychopathology, family adversity, and child’s IQ (Schreier et al., 2009). Suicidal outcomes can be the most tragic outcome (Kim & Leventhal, 2008).

34A number of studies show links between persistent bullying at school, and later antisocial behaviour and criminal offending (Farrington, Ttofi, & Lösel, 2011).

 Individual coping strategies

35Pupils adopt a variety of coping strategies when bullied. A substantial proportion of self-reported victims say that they have not told a teacher, or someone at home, about the bullying. A consistent finding is that rates of telling a teacher are less in older pupils, and boys (Hunter & Boyle, 2004). A study of 406 pupils aged 13-16 years found the five most frequent coping strategies were talk to someone, ignore it, stick up for yourself, avoid/stay away from bullies, and make more/different friends (Smith et al., 2004). Over a two year period, those who had stopped being victims more often had talked to someone about it (67%) than those who had stayed victims (46%) or become victims (41%). Telling teachers can be successful, but clearly needs a consistent and effective response from teaching staff. Telling adults, especially teachers, is particularly low for victims of cyber-bullying.

 School-based intervention/prevention

36Actions to reduce bullying in schools can be divided into these into broadly proactive strategies in the school and playground, designed to make bullying less likely to happen; peer support (which is both proactive and reactive); and reactive strategies, as ways of dealing with bullying incidents once they have occurred (Thompson & Smith, 2012).

37Proactive strategies include having a whole school policy on bullying, effective playground supervision, and curriculum work in the classroom. These are well developed for traditional bullying, and resources are being developed tailored for cyberbullying. A European resource, CyberTraining — A Research-based European Training Manual on Cyberbullying, is available at

38In peer support systems, selected students are trained to be peer supporters, to deal with interpersonal conflicts, social exclusion and bullying in proactive and non-violent ways. In primary schools, buddies and befrienders generally look out for pupils at breaktimes, who are upset or lonely. Playleaders or playground pals lead structured games activities. In the secondary sector, peer supporters, usually from older year groups, can be used to support younger students at transition and can also provide one to one mentoring/counselling for bullied students in a designated room. Crucial issues include the selection and training of peer supporters; the gender balance in recruitment (there are often more girl than boy volunteers, particularly in the secondary sector); adequate and continuing supervision by an accessible member of staff; effective promotion of the scheme; and sufficient take-up that peer supporters feel positive in their role. In a review, Cowie and Smith (2010) argued that schools using well-managed peer support schemes are seen as being more caring and concerned about pupil well-being, and the schemes are known and supported by pupils and staff; in addition, the peer supporters themselves generally benefit from the experience. There is evidence from individual cases that some pupils, who use peer support schemes for reasons of being bullied, report being helped. However most of the relevant studies do not report significant changes in general levels of bullying behaviour as a result of implementing a peer support scheme.

39A UK charity, Beatbullying, launched a new form of virtual peer support called CyberMentors in 2009. Students are trained as cybermentors, log on and mentor on demand. Cybermentors can refer mentees on to senior cybermentors and counselors for further support if necessary. This scheme is being extended to other European countries.

40Reactive strategies are a response to bullying incidents when they have happened. Reactive strategies range from sanction-based approaches, through restorative practices, to more indirect and non-punitive approaches. Direct sanctions range from verbal reprimands from the head teacher; meetings involving parents or carers; temporary removal from class; withdrawal of privileges and rewards; disciplinary measures such as detentions; punishment such as litter-picking/ school clean-ups; through to temporary or permanent exclusion. Restorative approaches aim to restore good relationships rather than mete out punishment; they include a hierarchy of flexible responses, ranging from informal conversations through to formal facilitated meetings or conferences. The underlying principle is to work to resolve conflict and repair harm. Non-punitive approaches include the Pikas method, and the Support Group Method. These do not hold the perpetrator responsible directly, but aim to change problem behaviours through a mixture of peer pressure to elicit a prosocial response, and self realisation of the harm and suffering caused to the victim. There is continuing controversy over the best balance between these approaches (Rigby, 2010; Thompson & Smith, 2012).

 Evaluations of program interventions

41There are anti-bullying programs available with a structured set of components and sequence of activities. The first was the Norwegian Nationwide campaign against bullying, which was launched through mass publicity in 1983, and involved a survey in schools; resources for teachers (curricular materials and videos) and advice for parents. This was developed by Olweus into the Olweus Bulling Prevention Program (OBPP) (Olweus, 1999; Olweus & Limber, 2010); this has school-level components, classroom-level components, individual-level components, and community-level component).

42An evaluation in the First Bergen Project (1983-85) involved 42 schools. The effect on rates of bullying was dramatic with reported victim rates falling by around 50%, for both boys and girls. A second Bergen project (1997-98) involved 14 intervention schools and 16 comparison schools. Bullying decreased by between 21-38% in intervention schools, with no change or increase in comparison schools. A first Oslo project (2001-2002) in 37 schools showed reductions of some 30-45% in victimisation and bullying. Olweus and Limber (2010) report findings associated with a New National initiative in Norway, with reductions in the range of 37%-49%. The success of the OBPP in Norway is thus substantial and well-replicated. The program has been used outside Norway, for example in Canada, Germany, the Netherlands, and the USA, but with less consistent success (Thompson & Smith, 2012).

43A recent and ongoing program in Finland, the KiVa Koulu program, is innovative in its methods and producing findings on a level with the OBPP in Norway (Kärnä et al., 2011). KiVa includes universal interventions (e. g. via the classroom) and targeted interventions (individual discussions with victims and bullying children, and using prosocial, high-status peers to be defenders). The classroom work includes an anti-bullying virtual learning environment; the KiVa computer game uses simulated characters and episodes learn facts and try out strategies, which can then be applied to everyday life at school. So far evaluations have been encouraging, with reductions of around 34-37%, with indications that both more disciplinary methods, and non-punitive approaches, can be helpful. Although primarily designed with traditional bullying in mind, evaluations so far show that KiVa is as effective in reducing cyberbullying as it is for a range of traditional forms (Salmivalli, Kärnä, & Poskiparta, 2011).

 Meta-analyses of large-scale interventions

44Ttofi and Farrington (2011) provide a meta-analysis of 44 school-based intervention programmes internationally. They found that on average, these reduced bullying by around 20-23% and victimisation by around 17-20%; although there is considerable variation in outcomes. They also examined, across programs, which program components were most associated with success. For reducing victim rates, most associated with success were use of videos, disciplinary methods, parent training/meetings, and cooperative group work; but work with peers was associated with a significant increase in victimization. For reducing bullying, most associated with success were parent training/meetings, improved playground supervision, disciplinary methods, school conferences, information for parents, classroom rules, classroom management and teacher training.

45The overall conclusion of reductions of around 20% or more appears a robust finding, and quite encouraging, even if many programs do not reach the success of OBPP in Norway, or KiVa in Finland. The conclusions drawn about individual component effectiveness are an important step forward, but likely to be less robust. Their analysis is limited historically in that the interventions surveyed cover some 25 years, whereas methods of intervention have been and still are being developed and changed. Some of Ttofi and Farrington’s analyses (for example, suggesting that work with peers is relatively ineffective; or that disciplinary methods are advantageous) depend very much on how terms such as “work with peers” and “disciplinary methods” are interpreted. The importance of different intervention components is still a matter of debate (Smith, Salmivalli & Cowie, 2012).

46The advent of cyberbullying in the last decade poses new challenges for anti-bullying interventions. There is considerable overlap in involvement in traditional forms of bullying and cyberbullying, but some distinctive features of cyberbullying also require other forms of intervention, including education on rights and responsibilities online (Bauman, 2010).


47The need for continuing anti-bullying work, in schools and other places used by children and young people, is obvious from current prevalence rates and the accumulating evidence of the causal influence of victimization on mental health issues and adjustment. Present indications are that bullying is not getting worse. Over the last two decades a range of anti-bullying interventions have become available, and are disseminated and widely employed, in schools in industrialised countries. Reviews suggest that these have some success and are worthwhile in terms of reducing suffering and ultimately enhancing school climate and good citizenship. There is still much to be learnt, particularly about the effectiveness of specific intervention components. Cyberbullying provides new challenges, as being a relatively new form of bullying with its own characteristics and somewhat different modes of effective intervention.

48School bullying is an area where research and practice have gone hand in hand, with good evidence that the outcomes have improved pupil well-being and happiness. The continuing synergy between research findings, both national and international, and policy and practice, has promise of building on the modest but significant successes so far, in creating safer environments in which children and young people can live, grow, play and learn.
