Olweus Bullying Prevention Program (BPP)

Program Background

An Historical Thumbnail Sketch
Bullying among school children is no doubt a very old phenomenon. The fact that some children are frequently and systematically harassed and attacked by other children has been described in literary works, and many adults have personal experiences of it from their own school days. Though many are acquainted with the "bully/victim problem," it was not until fairly recently—in the early 1970s—that efforts were made to systematically study it. For a number of years, these attempts were largely confined to Scandinavia. More recently, however, bullying among school children has received considerable public and research attention in countries such as England, Scotland, Ireland, Japan, Germany, Australia, Canada, and the United States.

A strong societal interest in bully/victim problems began in Sweden in the late 1960s and early 1970s, and the issue quickly spread to the other Scandinavian countries. In Norway, for example, bully/victim problems received attention from the mass media and was of great concern to teachers and parents for a number of years. At first, the school authorities did not officially address the phenomenon, but 15 years ago, a marked change took place. In late 1982, a newspaper reported that three 10-14 year old boys from the northern part of Norway had committed suicide, in all probability as a consequence of severe bullying by peers. This event generated considerable uneasiness in the mass media and general public, and eventually it triggered a chain of reactions which ultimately resulted in a nationwide campaign against bully/victim problems in Norwegian primary and junior high schools, launched by the Ministry of Education in the fall of 1983.

The Olweus Bullying Prevention Program described in this Blueprint was developed, refined, and systematically evaluated in an intervention project involving 2,500 children in 42 schools from the city of Bergen, Norway, during the two-year period from 1983 through 1985 (Olweus, 1991; 1993a; 1994). There have been several recent replications of the program, both within Norway and in several other countries, including the United States. Whitney and colleagues (Whitney, Rivers, Smith, & Sharp, 1994) implemented and evaluated the effectiveness of the program in 16 primary and 7 secondary schools in Sheffield, England. Hanewinkel and Knaack (1997) tested the Olweus Bullying Prevention Program among approximately 6,400 3rd-9th graders in Schleswig-Holstein, Germany. The first systematic evaluation of the program within the United States was conducted by Melton and colleagues (Melton et al., 1998) and involved 6,388 elementary and middle school children from non-metropolitan communities in South Carolina. Most recently, a new large-scale intervention project involving 3,200 students in 30 schools was initiated in Bergen, Norway. Although all of the replications were true to the goals and approach of the original Norwegian model, several projects (most notably the Sheffield and South Carolina initiatives) made several additions and modifications to the model in order to meet the perceived needs of the particular populations. These replication projects are described in detail in Chapter 4.

What is Bullying?
Bullying or victimization can be generally defined in the following way: A student is being bullied or victimized when he or she is exposed, repeatedly and over time, to negative actions on the part of one or more other students. Such negative actions include intentionally inflicting, or attempting to inflict, injury or discomfort upon another. These behaviors can be carried out physically (e.g., hitting, kicking, pushing, choking), verbally (e.g., by calling names, threatening, taunting, malicious teasing, spreading nasty rumors), or in other ways, such as making faces or obscene gestures, or intentional exclusion from a group. The latter (usually more subtle) forms are usually termed "indirect bullying," whereas "direct bullying" comprises behaviors that represent relatively open (usually verbal or physical) attack on the victim.

In order to be considered bullying, there should also be an imbalance in power or strength (an asymmetric power relationship). In other words, students who are exposed to the negative actions generally have difficulty in defending themselves and are somewhat helpless against the student or students who harass. It is not considered bullying when two students of approximately the same physical or psychological power are in conflict, nor is friendly or playful teasing considered bullying. However, repeated degrading and malicious teasing which is continued despite clear signs of distress and opposition on the part of the target does qualify as bullying.

In the context of school bullying, the victim is usually a single student, who is generally harassed by a group of two or three students, often with a "negative leader." A considerable proportion of the victims, 20-40 percent, report, however, that they are mainly bullied by a single student.

Bullying is thus characterized by the following three criteria: (a) it is aggressive behavior or intentional "harmdoing;" (b) it is carried out repeatedly and over time; and (c) it occurs within an interpersonal relationship characterized by an imbalance of power. One might add that bullying behavior often occurs without apparent provocation. These characteristics clearly suggest that bullying can be considered a form of abuse: peer abuse. What sets it apart from other forms of abuse such as child or domestic abuse is the context in which it occurs and the relationship of the interacting parties.

The following newspaper clippings illustrate two forms of bullying:

For two years, Johnny, a quiet 13 year-old, was a human plaything for some of his classmates. The teenagers badgered Johnny for money, forced him to swallow weeds and drink milk mixed with detergent, beat him up in the rest room, tied a string around his neck, and led him around as a "pet." When Johnny's torturers were asked about the bullying, they said they pursued their victim because "it was fun."

............

Having a child who is bullied means seeing your child become an outcast, frozen out and completely isolated. But most of what you read is about bullies and victims who are boys. Bullying is to be found amongst girls, but it is not so obvious from the outside. It is not usually a matter of damaged clothes or damaged arms and legs. Bullying amongst girls bypasses physical pain and goes right into the soul. Bullying amongst girls is less concrete or visible.

How can I as a mother accuse the girls bullying my 14-year-old daughter for having stopped phoning, for not saying hello, for speaking badly of her behind her back, for changing places in the classroom, for always commenting on and making fun of what she says, etc. Nothing they do (or don't do) is against the rules.

As a mother, I have a great sense of grief and helplessness in the face of what my daughter has to go through. In desperation I have tried to talk to the mothers of two of my daughter's previous friends. It wasn't particularly helpful; some parents just can't accept that their children are criticized by outsiders. They defend their children at any cost, no matter how ridiculous this may be.

I wouldn't wish the grief and helplessness I feel on any parents, but I wish you and your children could actually feel just for a short time what my daughter and our family have had to live with for the last six months or so. Then perhaps you would understand.

—Despairing mother

Prevalence of Bullying
According to more than 150,000 Norwegian and Swedish students who completed the Olweus Bully/Victim Questionnaire, 15 percent (1 out of 7) of the students in Norwegian or Swedish elementary and lower secondary/junior high schools (grades 1-9, roughly corresponding to ages 7 -16) are involved in bully/victim problems. Approximately 9 percent are victims and 7 percent bullied other students (see Figures 1 and 2). A relatively small percentage of the students are both victim and bully (1.5 percent of the total student population, or 17 percent of the victims). Five percent of the students are involved in more frequent bullying problems (as bullies or victims or bully/victim), occurring once a week or more frequently. As the prevalence questions in the Questionnaire typically refer to a limited time period of three to five months, there is little doubt that the figures presented actually underestimate the number of students involved in such problems during a whole year.


These figures emphasize that bullying is a considerable problem in Norwegian and Swedish schools, affecting a very large number of students. Moreover, data collected in many other countries (primarily collected with the Olweus Bully/Victim Questionnaire), including the United States, clearly indicate that these problems are not limited to Scandinavia. In fact, the prevalence rates in these countries are as high, if not higher, than those reported in Scandinavia.

For example, in a recent large-scale study (Melton et al., 1998) of more than 6,000 middle school students from grades 4 through 6 in rural South Carolina, 23 percent reported that they had been bullied by other students "several times" or more frequently during the past three months. Approximately 20 percent reported that they had bullied other students with the same frequency (see Figures 3 and 4).

It should be emphasized, however, that comparisons of prevalence figures from different countries must be made with considerable caution. In spite of the fact that the Questionnaire gives a fairly detailed definition of bullying (written in simple language), it is likely that prevalence rates will be affected by the students' familiarity with the concept of bullying, the degree of public attention to the phenomenon and similar factors. At the same time, it should be underscored that the general pattern of findings and interrelationships, such as gender and age trends, has been found to be fairly similar across countries and cultures, suggesting that the existence of a phenomenon has some relatively universal characteristics.

In terms of gender differences, boys are much more likely to bully others than are girls, and a relatively large percentage of girls report that they are bullied mainly by boys. Also, a slightly higher percentage of boys report being victims of bullying. Although direct bullying is a greater problem among boys, bullying also occurs among girls. Girls are less apt to use physical means of bullying; instead, they use more subtle and indirect ways of harassment such as slandering, spreading rumors, intentionally excluding others from the group, and manipulating friendship relations (e.g., depriving a girl of her "best friend"). In addition, these forms of bullying may be more difficult for adults to detect.

Age trends in bullying also exist. Generally, younger and weaker students are more often exposed to bullying. Although most incidents occur among students in the same grade, a good deal of bullying is also carried out by older students towards younger ones. (More details about bullying in different grades and among boys and girls are given in, Olweus, 1993a; Melton, et al, 1998).

Most bullying occurs on the playground or in the classroom (in Norway, 65 percent and 38 percent, respectively; in the U.S., 26 percent and 29 percent, respectively), but these behaviors also occur in hallways/corridors, the gymnasium, the locker room, and the bathroom. Although a substantial portion of students are bullied on their way to and from the school, this percentage is usually considerably lower than the percentage being bullied at school.

Why Focus on Bully/Victim Problems?

There are several key reasons for examining and attempting to counteract bully/victim problems in school relating to:

  • The short-term effects on the victims
  • The long-term effects on the victims
  • The long-term effects on the bullies, if the bullying behavior goes unchecked
  • School social climate

Each of these points is elaborated below.

Short-term Effects on Victims. In addition to being painful and humiliating, bullying experiences make victims unhappy, distressed, and confused. These students tend to lose self-esteem and become anxious and insecure. Moreover, victims may suffer physical injury, their concentration and learning may be affected, and they may refuse to go to school. They may tend to feel stupid, ashamed and unattractive, and gradually begin to view themselves as failures. Many of the victims develop psychosomatic symptoms such as headaches and stomach pains. In some cases, the victims' devaluation of themselves becomes so overwhelming that they see suicide as the only possible solution.

Long-term Effects on Victims. Persistent bullying during the school years may also have long-term negative effects on the victims many years beyond school (Olweus, 1993b). As young adults (age 23), former victims (who were bullied primarily in grades six through nine) tended to be more depressed and had poorer self-esteem than their nonvictimized peers. The pattern of results suggested that earlier, persistent bullying can leave many scars. Thus, it is obviously crucial to stop bullying in school in order to reduce and prevent its negative, short and long-term consequences.

Long-term Effects on Bullies. Bullying is not just isolated behavior on the part of its perpetrators; instead, it is part of a more generally antisocial and rule-breaking (conduct-disordered) behavior pattern. As our research has shown, students (particularly boys) who bully others are especially likely to engage in other antisocial/delinquent behaviors such as vandalism, shoplifting, truancy and frequent drug use. We have also found that this antisocial behavior pattern often continues into young adulthood. Approximately 60 percent of boys who were characterized as bullies in grades 6-9 (on the basis of both teacher nominations and peer ratings) had been convicted of at least one officially registered crime by the age of 24, compared to 23 percent of boys who were not characterized as bullies. Even more dramatic, as many as 35-40 percent of the former bullies had three or more convictions by this age, while this was true of only 10 percent of the control boys (those who were neither bullies nor victims in grades 6-9). Thus, as young adults, the former school bullies had a fourfold increase in the level of relatively serious, recidivist criminality as documented in official crime records (Olweus, 1993a). With regard to (potential) bullies, then, it is important to try to stop their development along an antisocial pathway and to redirect it in a more prosocial direction.

School Social Climate. In addition, there is a connection between the level of bully/victim problems in a classroom or school and aspects of the social climate of the unit concerned. In classrooms or schools with high levels of bullying problems, students tend to feel less safe and are less satisfied with school life. This implies that, for many students, and particularly for the victims, the classroom is no longer a place of concentrated work and learning.

A classroom or school climate characterized by bully/victim problems may have other negative effects. It is natural to assume that most students in a classroom or a school are affected by a bully/victim problem in some way. For example, if a "neutral" student observes bullying behavior going unchecked, possibly with open or tacit support from other students or even the teacher, this will teach him or her to regard bullying behavior as acceptable. Over time, such episodes can result in harsher, less empathetic social climates which foster new bullying episodes and other problems. Conversely, classrooms or schools with a friendly and positive social climate are likely to elicit and encourage different, more appropriate reaction patterns in their students. Accordingly, when counteracting bullying, it is important to involve the students surrounding the bully/ies and the victim and affect their views regarding bullying behavior. The various roles and related attitudes that other students in the class or school may adopt regarding bully/victim problems are portrayed in the "bullying circle," shown in Figure 5.

Theoretical Rationale/Conceptual Framework

Common Myths About Bullying
In the public debate, several hypotheses about the causes of bully/victim problems have been advanced. Even though these have failed to receive support in controlled, empirical research, they are still quite popular, and it is important to briefly discuss and dispel some of these myths.

One assumption is that bully/victim problems are, in part, a consequence of large classes and/or schools: the larger the class or the school, the higher the level of bully/victim problems. Closer analysis of this hypothesis, using the Norwegian survey data from more than 700 schools and several thousand classes (with great variations in size) reveals that the size of the class or the school is of negligible importance for the relative frequency or level of bully/victim problems (Olweus, 1993a). Moreover, a large-scale Irish study has found an inverse relationship: the larger the class or the school, the lower the level of bully/victim problems (e.g., O'Moore, Kirkhan, & Smith, 1997).

Second, it has been commonly maintained that bullying is a result of competition and striving for grades in school. More specifically, it has been argued that the aggressive behavior of the bullies toward their environment can be explained as a reaction to failures and frustrations in school. This hypothesis has also failed to receive support from detailed analyses of longitudinal data. Though there was an association (of moderate magnitude) between aggressive behavior and (poor) grades, no evidence suggests that aggressive behavior is a consequence of poor grades and failure in school (Olweus, 1983).

Third, a widely held view, especially among students, is that external deviations cause victimizations. It is argued that students who are fat, red-haired, wear glasses, speak with an unusual dialect, or have a different ethnic background, for example, are particularly likely to become victims of bullying. This hypothesis received no support in empirical analyses in several European studies (e.g., Junger, 1990; Olweus, 1978), and suggests that external deviations play a much smaller role in the origin of bully/victim problems than generally assumed. The relationship between ethnic background and victimization has not been closely examined in the United States, however. Given the greater ethnic heterogeneity of the U.S., it is possible that ethnic background may be related to victimization.

It may be added that in the case of Scandinavian students, being a bully or a victim is unrelated to the socioeconomic conditions of the student's family such as parental education or income. Accordingly, the common belief that bullying behavior is more prevalent in lower social classes can be considered a myth as regards Scandinavia. However, this hypothesis has not yet been well investigated in large-scale North-American studies. Given the greater socioeconomic heterogeneity of the U.S., it is possible that there may be such link, although it is likely to be weak.

Causes of Bullying
All of these assumptions or hypotheses have failed to receive support from empirical data. As a result, one must look for other factors to determine the (partial) origins of these problems. In this context, it is important to realize that the search for causes must be conducted at different levels of analyses, including the individual, the classroom, and school levels. The research evidence collected to date clearly suggests that personality characteristics and typical reaction patterns, in combination with physical strength or weakness in the case of boys, are quite important for the development of these problems in individual students (making them more likely to become victims or bullies). At the same time, environmental factors such as the teachers' attitudes, routines, and behaviors play a major role in determining the extent to which the problems will manifest themselves in a larger unit such as the classroom or the school. In addition, environmental-organizational factors such as the way in which break periods are arranged, may be of some importance.

Basic Principles
Given the considerable stability of aggressive behavior over time and the generally low or modest success in reducing such behavior with a number of individual-oriented approaches, an important premise of the Olweus Bullying Prevention Program is that bullying behavior can be checked and redirected into a more prosocial direction through a systematic restructuring of the social environment. Among other outcomes, this restructuring is expected to result in fewer opportunities for bullying behavior and fewer or smaller rewards (e.g., in the form of prestige or peer support) for displaying such behavior. More specifically, the program aims to effect systematic changes of the "opportunity" and "reward structures" for bullying and similar behavior in the school and other relevant contexts. In addition, positive, friendly, and prosocial behaviors are encouraged and rewarded.

Generally, the Olweus Bullying Prevention Program is built around a limited set of key principles and findings derived chiefly from research on the development and modification of problem behaviors, particularly aggressive behavior. More specifically, the program strives to develop a school (and ideally, a home) environment:

  • characterized by warmth, positive interest, and involvement by adults;
  • firm limits to unacceptable behavior;
  • where non-hostile, nonphysical negative consequences are consistently applied in cases of violations of rules and other unacceptable behaviors; and,
  • where adults act as authorities and positive role models.

The first three principles represent the antithesis of child-rearing dimensions that research has linked to the development of aggressive reaction patterns: negativism on the part of the primary caretaker, general permissiveness, lack of clear limits, and use of power-assertive methods such as spanking and violent verbal outbursts. The fourth principle encourages adults to emulate an authoritative (not authoritarian) adult-child interaction model in which they take responsibility for the students' total situation, including both academic learning and social relationships in school.

A basic premise of the Olweus Bullying Prevention Program is that most efforts to create a better school environment must be initiated and driven by the adults at school. However, a number of the program measures (below) include the students in these efforts. Moreover, the students' role in changing the normative context of the school will gradually increase in importance as the program evolves.

Brief Description of Intervention

General Prerequisites: Awareness and Involvement
Adult behavior is crucial to the success of the Bullying Prevention Program, and in order to achieve the program's goals the following two conditions must be met. First, the adults at school and, to some degree, at home must become aware of the extent of bully/victim problems in their own school. Secondly, the adults must engage themselves, with some degree of seriousness, in changing the situation. Without adults' acknowledgment of schools' existing bully/victim problems and a clear commitment by a majority of the school staff to participate actively in the anti-bullying efforts, the program is likely to have limited success. Administration of the Olweus Bully/Victim Questionnaire is usually an effective way to achieve awareness and involvement. In general, staff members will be more inclined to initiate countermeasures if they realize the number of students in their own school who are directly involved in bully/victim problems and learn how these problems affect students.

Interventions at the School, Class, and Individual Levels
The principles described above have been translated into a number of specific measures, or interventions, that are used at the school, class, and individual levels, and taking action at all of these levels is vital to counteract bully/victim situations. In this way, students will be exposed to consistent messages, from different persons/sources and in different contexts, regarding the school's views of and attitudes toward bullying. All of the components are very important; however, the focus has been to highlight adult involvement because adults are the key implementors of the program. The basic message of the program is successfully demonstrated through all the components: Bullying is not accepted in our class/school, and we will see to it that it comes to an end.

Table 1 presents an overview of the components that are considered, on the basis of both statistical analyses and our experience with the program, to be particularly important in any implementation of the Bullying Prevention program.

School Level. Core interventions at the school level include administration of the Olweus Bully/Victim Questionnaire to assess the nature and prevalence of bullying at each school, a school conference day/meeting, formation of a Bullying Prevention Coordinating Committee, and the development of a coordinated system to supervise students during break periods. The school conference day provides an opportunity for program consultants and school personnel to review results of the survey, discuss elements of the Olweus Bullying Prevention Program, and make specific plans for implementing the program during the upcoming school year. Ongoing coordination of the school's efforts will be guided by a Bullying Prevention Coordinating Committee, which may include a school administrator, a teacher representative from each grade, a guidance counselor and/or a school-based mental health professional, and parent and student representatives. The final core component, increasing teacher supervision of students in locations where bullying occurs most frequently at school, can be implemented after the Questionnaire has identified particular "hot spots" within a school, which commonly include the playground, classroom, and lunchroom.

Classroom Level. Core program interventions at the classroom level include establishing and enforcing specific rules against bullying, as well as holding regular classroom meetings with students to discuss various aspects of bullying and related antisocial behaviors and adherence to agreed upon classroom rules. Classroom meetings also are used to engage students in a variety of activities (e.g., role playing, writing, and small-group discussions) through which they gain a better appreciation of the harm caused by bullying and learn strategies to combat it. Meetings with parents to foster their active involvement are considered highly desirable components both at the classroom and the school levels.

Individual Level. Additional core components of the program involve interventions with individual bullies (or small groups of bullies), victims, and their parents to both ensure that bullying behaviors cease and that victims receive necessary support to avoid future bullying.

In order to foster the implementation and execution, the program emphasizes using the existing social environment: teachers and other school personnel, students, and parents. Thus, non-mental health professionals play a major role in the desired restructuring of the social environment. However, experts such as school mental health professionals, guidance counselors, and social workers also serve important functions as planners and coordinators, in counseling and consulting with the school, and in possibly handling more serious cases.

Evidence of Program Effectiveness

The Olweus Bullying Prevention Program has been implemented in a variety of cultures (e.g, Bergen, Norway; the southeastern United States; Sheffield, England; and the state of Schleswig-Holstein, Germany) and school contexts (elementary, middle, and junior high schools). The first and most comprehensive evaluation was conducted with 2,500 students from elementary and junior high schools in Bergen, Norway, between 1983 and 1985. Results from this quasi-experimental study revealed substantial reductions (typically by 50 percent or more) in the frequency with which students reported being bullied and bullying others. Roughly similar results were obtained using peer and teacher ratings of levels of bully/victim problems. Furthermore, there were substantial reductions in students' reports of participation in general antisocial behaviors such as vandalism, fighting, theft, and truancy. Improvements were also observed in the social climate of classrooms. Students reported better order and discipline at school, more positive social relationships, and more positive attitudes toward schoolwork and school. The effects of the program appeared to be cumulative: for some of the outcome variables studied, the program effects were more marked after 20 months than after 8 months of intervention. Finally, a "dosage-response" relationship was documented: those classrooms that had implemented certain essential components of the intervention program (including establishment of classroom rules against bullying and use of regular classroom meetings) showed larger reductions in bully/victim problems than those classrooms that implemented fewer components.

Evaluations of programs in the United States, England, Germany, and a subsequent study in Bergen, Norway, have produced somewhat more modest but still quite positive findings. For example, the U.S. study of middle school students revealed significant decreases in students' self-reports of bullying in the intervention schools compared to control schools. Moreover, the program appeared to slow the natural rate of increase in students' engagement in several other antisocial behaviors.
