The role of family and school-level factors in bullying and cyberbullying: a cross-sectional study

Bullying is defined as repeated and harmful behaviour, characterised by a strong imbalance of power between the bully and the victim [1]. Involvement in bullying behaviours is a widespread phenomenon in childhood and adolescence that can have a negative impact on health such as later anxiety problems [2], depression and self-harm [3, 4], antisocial behaviour [5], and suicide or attempted suicide [6, 7], as well as substance misuse and poor educational outcomes [8].

Researchers have investigated the characteristics of adolescents who are involved in bullying behaviours. In a meta-analysis of 28 studies, Tippett and Wolke [9] found a significant but weak association between low socio-economic status (SES) and being a victim of bullying. Bullying behaviours differ across sex and ethnicities. For example, males have been found to engage in bullying behaviours that are more physical in nature (such as hitting or kicking other classmates) than females, who seem to exhibit more relational bullying behaviours (such as excluding classmates or spreading rumours about them) [10]. A study conducted in the UK [11] highlighted differences in bullying subtypes across ethnicities, with Pakistani and Caribbean girls more often being perpetrators of bullying than girls in other ethnic groups.

There is evidence that characteristics of the school can also influence bullying. For example, the size of the school [12] and the neighbourhood in which the school is located [13, 14] have been associated with bullying behaviours, with schools with a large number of students showing higher proportions of bullying behaviours, and low school/neighbourhood SES being associated with higher rates of bullying behaviours. However, we do not know the relationship between other school-level factors and bullying behaviours.

Recently, a new form of bullying has emerged, labelled “cyberbullying,” which is defined as an aggressive act carried out by a single individual or a group of individuals using electronic forms of contact [15]. Research on cyberbullying is at an early stage but we know that the experience of being cyberbullied is very distressing [16].

The family and socio-demographic characteristics of those who engage in cyberbullying have been little studied and most data currently available come mainly from the USA [17].

The aim of this exploratory study is to fill the gaps highlighted above by investigating a range of school characteristics that may be associated with 1) bullying victimization and 2) cyberbullying (victimization and perpetration). Understanding whether and what school-level characteristics have an impact on students’ behaviour is particularly important to guide and implement intervention programs that target schools.

We used data from the baseline survey of the INCLUSIVE study, a cluster randomized controlled trial of an intervention aimed at reducing bullying and aggressive behaviours in 11 to 16 year old students in secondary schools. Baseline data were collected before randomization in May–June 2014 from all Year 7 classes (age 11–12 years) in 40 participating secondary schools within the state education system across south-east England. Full details of the sampling methodology are available in the study protocol [18]. Schools exclusively for those with learning disabilities, behaviour problems (e.g. student referral units) and very poorly performing schools with an Ofsted rating of “Inadequate” were not included in the sample [18]. Data were collected through questionnaires completed in school in confidential sessions supervised by the research team. A total of 6667 students provided baseline data. Students provided demographic details by self-report. Other student-level outcome measures were also assessed by self-report as follows.

Data were available for 6667 (3103 males, 47%) Year 7 students (mean age = 11.8, SD = 0.4) in 40 schools in south-east England. Of these, 39.4% were White British, 25.0% were Asian or Asian British, 14.0% were Black or Black British, 8.5% were White (other), 7.0% reported having mixed ethnicity, 1.0% were Chinese or Chinese British, and 5.1% were from other ethnic groups.

This is the first study to examine both student- and school-level factors associated with bullying victimization and cyberbullying in a large sample of English young people. We found that 32% of boys and 38% of girls report bullying victimization (either frequent or distressing, or both) with 10% of boys and 14% of girls reporting severe bullying (frequent and distressing) over the same period. Bullying through online methods (cyberbullying victimization) was reported by 2% of boys and 4.5% of girls, with 1% of boys and 0.5% of girls reporting being cyberbullies. Bullying of all types varied significantly by school, although the school-level explained only 1.9% to 2.5% of the variance of bullying across the sample.

Bullying victimization and cyberbullying victimization were reported more often by girls. A potential explanation for this result is that girls are more likely to be exposed to bullying from both other girls and boys as well (i.e. with the latter engaging in more gender-based violence such as sexual harassment or sex-based jokes), as opposed to boys, who might be bullied primarily by other boys and less likely to be bullied by girls. Therefore, this may reflect an actual difference in terms of frequency and emotional distress associated with victimization across gender in our sample. Another potential explanation is that girls are more likely to report actual frequency and levels of distress associated with victimization compared to males, perhaps as a consequence of less shame associated with reporting being bullied compared to boys, but this remains highly speculative. We found minimal association between bullying and cyberbullying and ethnicity, aside from a low significance association between mixed ethnicity and cyberbullying perpetration. This result adds to a scenario of mixed findings, where the relationship between ethnicity and peer aggression is still unclear. Those from more deprived families were more likely to be victims of cyberbullying but also cyberbullying perpetrators. Students with a lone parent were found to be more likely to be bullied and cyberbullied. The school-level factors independently associated with bullying risk were school quality rating and school type. An Ofsted rating of “Good” was associated with higher risk of significant bullying compared with schools rated “Outstanding”. These findings were independent of other school-level factors including school type.

This finding suggests that school organisations that perform well in terms of leadership and management engender school climates that are protective against bullying. We recognise that Ofsted ratings take into account a number of aspects of a school aside from leadership and management, including school ethos, awareness of bullying behaviours and how to prevent and manage them. We speculate that these latter aspects of Ofsted are particularly important in explaining why students in “Outstanding” schools report lower bullying victimization scores compared to schools with an Ofsted rating of “Good”. We recognise that school level factors other than those measured in the present study are likely to influence bullying behaviours (i.e. staff health and well-being). Note that the lowest Ofsted rating (“Requires improvement”) was not associated with bullying risk, possibly due to the small number of schools in this category.

Students in voluntary-aided schools (faith schools in our sample) were less likely to be bullied compared to those in the largest group of schools, i.e. mainstream state schools that had recently converted to academy status. This supports the notion that elements of school ethos and culture are protective against bullying. Alternative hypotheses include that faith schools might attract students from families in whom bullying is less common or where children are more resilient to being bullied. In contrast, cyberbullying perpetration was more common amongst community and foundation schools compared to converter academy mainstream schools. The reasons for this are unclear and need to be investigated further in longitudinal samples. We did not find that the sex intake of a school was strongly associated with bullying, although an interaction between family affluence and school sex suggested that the association of high SES with lower risk of bullying is stronger in boys-only schools than in girls-only or mixed schools.

We investigated whether school-level factors influence bullying and cyberbullying in a large sample of secondary school students. School type and school quality measures were associated with bullying risk. These preliminary findings pave the way for future research investigating which school factors and processes promote or prevent bullying and inform development of interventions to prevent bullying and cyberbullying in schools.
