Bullying Involvement in Adolescence: Implications for Sleep, Mental Health, and Academic Outcomes.

Adolescents' involvement in bullying is associated with both sleep and mental health problems, but the nature of this association remains unclear; further, its association with academic outcomes has received little attention. Thus, the aims of the current study were to (a) determine whether involvement in bullying as a victim, bully, or bully-victim was associated with greater sleep and mental health problems and (b) explore the potential mediating effect of sleep and mental health problems on the association between bullying and academic outcomes. A large 2012 population-based study in Hordaland County, Norway, surveyed 10,220 adolescents (16-19 years; 54% girls) about bullying involvement using the revised version of the Olweus Bully/Victim Questionnaire, detailed sleep assessment, and mental health questionnaires. Academic outcomes were obtained from official administrative registries. 1.7% of the adolescents (n = 156) reported being victims of bullying, 1.0% (n = 92) reported being a bully, and 0.5% (n = 50) reported being a bully-victim. All categories of bullying involvement had higher rates of mental health problems compared with adolescents not involved in bullying. Victims reported more symptoms of anxiety and depression, whereas bullies reported higher rates of conduct problems. Adolescents in all bullying categories also reported significantly shorter sleep duration and higher prevalence of insomnia as well as lower grade point average (GPA) compared with adolescents not involved; however, school absence was not associated with bullying involvement. Bullying involvement and GPA showed complete mediation for bullies and bully-victims and partial mediation for victims through sleep duration, conduct problems, and symptoms of depression and attention deficit hyperactivity disorder (ADHD). Bullying is strongly associated with mental health and sleep problems, in addition to lower academic performance. Findings support the importance of addressing bullying involvement during this important developmental period.

Long-term school-level effects of the Olweus Bullying Prevention Program (OBPP).

In agreement with two predictions, this somewhat unusual study documented that 70 elementary schools (A-schools) with continued and repeated use of the Olweus Bullying Questionnaire (OBQ) in a four-year follow-up period of 2007-2010, two to eight years after original implementation of the Olweus Bullying Prevention Program (OBPP), had a clearly more favorable long-term development in terms of being-bullied problems, as measured with a completely independent data source, the National Pupil Survey than 102 comparable schools (B-schools) that had not conducted any OBQ-surveys in the same period. The odds of being bullied for students in a Norwegian average elementary school were also almost 40% higher than for students who attended a school with continued use of the OBQ, and very likely, other components of the program. Several alternative explanations of the findings were explored and found wanting. Results suggested that A-schools with continued use had changed their "school culture" for the better with regard to awareness, preparedness and competence in handling and preventing bullying. This form of 'organizational learning' has major consequences in that new groups of students will benefit from such a school environment. It was generally concluded - in spite of a highly stable average of the level of bullying problems in Norway - that it is fully possible to substantially reduce such problems not only in one-year evaluations, as has been amply documented before, but also in the long term, up to eight years after original implementation, with a program such as the Olweus Bullying Prevention Program.

Bullies and victims at school: are they the same pupils?

BACKGROUND: The reported prevalence of bully-victims and aggressive/provocative victims varies quite considerably in previous research, and only a few studies have reported prevalence rates across grades. There is also a lack of detailed analyses of the extent to which victims are also bullies, and bullies are also victims. AIMS: To study the prevalence of male and female bully-victims across grade/age and to establish the degree of overlap or relative size of the bully-victim group by relating them to all victims, all bullies and all involved students. SAMPLES: Participants in Study 1 were 5,171 pupils in grades 5-9 from 37 schools. Study 2 comprised 12,983 pupils in grades 4-10 from 66 schools. METHODS: The Olweus Bully/Victim Questionnaire was administered to the pupils in their ordinary classrooms. RESULTS: The prevalence of bully-victims was low and mainly declined across grades. There were far more boys than girls in the bully-victim group. Bully-victims resembled victims only (pure victims) in terms of age-trends and bullies only (pure bullies) in terms of sex composition. The overlap of bully-victims with the total victim group was fairly small (10-20%) in all grades. In primary grades, bully-victims constituted about 30-50% of the total bully group, whereas in higher grades these proportions were considerably lower. CONCLUSION: Our analyses and overview of previous research suggest that the bully-victim group is small, and that the large variations across studies are mainly due to differences in choice of cutoff point. Bully-victims should generally be seen and treated statistically as a distinct subgroup. The relatively larger proportion of bully-victims in lower grades should be explored further.
