Participant Roles in Bullying:
How Can Peer Bystanders Be
Utilized in Interventions?
This article provides a view of school bullying as
a group phenomenon and practical implications
stemming from this approach. The motivation
for bullying perpetration often relates to one’s
social standing in the group. Peer bystanders are
typically present when bullying takes place, often
providing the perpetrators with social rewards.
The more such rewards (e.g., laughing, cheering)
are present and the less the victimized children
are supported and defended, the more likely
bullying is maintained in a classroom or a peer
group. However, bystanders are not necessarily
aware of the consequences of their responses
when witnessing bullying, and they may not know
how to support and defend vulnerable peers.
In interventions aiming to reduce bullying, peer
bystanders’ awareness of their own role, their
empathy toward victimized youth, as well as their
self-efficacy related to defending those youth
should be enhanced. Intervention evaluations
have shown that changing bystander responses
to bullying is a fruitful way to reduce bullying
and victimization.

Reward Bullying?

Swettenham, 2001) captures something essential
about the recent view of bullying: It has a
function for the perpetrator. Bullying is a highly
prevalent phenomenon which often persists over
long periods of time, because “it works”; in other
words, it helps the perpetrator get something that
he or she wants.
To prevent and tackle bullying, one must un-
derstand what a child or an adolescent acquires,
or attempts to acquire, by bullying others. Al-
though the perpetrators of bullying are not all the
same (Peeters, Cillessen, & Scholte, 2010), for
many of them bullying seems to be motivated by
286

Salmivalli Participant Roles in Bullying
the pursuit of visibility, power, and a high status
in the peer group (Houghton, Nathan, & Tay-
lor, 2012; Salmivalli, 2010; Sijtsema, Veenstra,
Lindenberg, & Salmivalli, 2009; Veenstra et al.,
2007). For that reason, bullies need bystanders,
or spectators. They do not want to attack their
target in a situation where there are no witnesses
around. Rather, they choose a time and place
where other peers (but no adults) are present:
in its very core, bullying is about public abuse
and ridicule of another person. Observational
studies in school playgrounds confirm that this
is the case: in most bullying situations, there is
a group of peers present (Hawkins, Pepler, &
Craig, 2001).
Rather than intervening on behalf of the
victimized peer, many bystanders reinforce the
bully’s behaviors by verbal or nonverbal cues
that are socially rewarding as they signal that
bullying is acceptable, or even funny and enter-
taining (Salmivalli, 2010; Salmivalli, Lagerspetz,
Björkqvist, Österman, & Kaukiainen, 1996). For
instance, bystanders may be laughing or cheer-
ing when the bullying is taking place. Mak-
ing others laugh is already rewarding for the
child doing the bullying, and such a response
from peers is likely to prolong the bullying
episode. Other bystanders are even more active
and assist the bully by catching the targeted
child, or by preventing him or her from es-
caping during episodes of physical aggression
or other types of humiliation. Other peers may
just silently witness what is happening, without
acknowledging that the bully might interpret such
behavior as an approval of his or her mean
acts. Luckily, some children support the victim
or try to make others stop bullying. Within
the research line that started in the 1990s, the
different ways of responding while witnessing
bullying have been labelled participant roles:
reinforcer (of the bully), assistant (of the bully),
outsider, and defender (of the victim; Salmivalli
et al., 1996; Sutton & Smith, 1999). Later on,
outsiders have also been called silent approvers
of bullying; this captures better the idea that they
are not completely noninvolved either but might,
through their inaction, be involved in maintaining
bullying.
How come bystanders reward bullying, even if
antibullying attitudes are common among school-
aged children and youth (e.g., Rigby & Slee,
1991; Salmivalli & Voeten, 2004)—why aren’t
such attitudes expressed in public? First, although
it might be difficult (or unpleasant) to believe,
youth who bully others are often perceived as
popular by their classmates, especially during
adolescence (e.g., Caravita, DiBlasio, & Salmi-
valli, 2009; Peeters et al., 2010). Longitudinally,
youth who engage in aggressive behavior be-
come increasingly popular over time (Cillessen
& Borch, 2006). In a study by Juvonen, Graham,
and Schuster (2003), bullies were perceived as
cool and those who continued their bullying
behavior from fall to spring even became more
cool over the course of the school year. That
is probably one reason why bystanders are not
eager to intervene on behalf of the victim: They
may be worried about their own status in the
group, or about the possibility of ending up the
next victims themselves.
The second mechanism that prevents people
from expressing antibullying attitudes in public
has been referred to as “pluralistic ignorance”
(Juvonen & Galvan, 2008, pp. 233–234). When
no one challenges the behavior of the bullies,
students come to (falsely) perceive each other
as approving of it. As a consequence, each
individual member of the group might believe
that “although I don’t personally like bullying,
everyone else seems to think it is okay.” Such
a misperception of peer group norms further
prevents students from intervening.
Finally, the perpetrators of bullying are typ-
ically selective in their aggression. By choos-
ing targets who are submissive and insecure
(Schwartz et al., 1998), or in a low-power po-
sition in the group (e.g., Hodges & Perry, 1999;
Salmivalli & Isaacs, 2005), bullies can maximize
the social rewards they gain from peers while
minimizing their loss of affection (Veenstra, Lin-
denberg, Munniksma, & Dijkstra, 2010). If they
targeted peers who had many friends, or who
were highly liked by classmates at large, students
doing the bullying would be more likely to be
confronted or rejected by these friends, or by
classmates in general.

Theories of Bullying and Cyberbullying
To sum up, bullies desire to be visible,
powerful, and popular. Unfortunately, research
demonstrates that it is possible for them to reach
such goals by bullying others. The peer group
rewards the perpetrators of bullying in at least
two ways: by expressing approval (or by not
expressing disapproval) during actual bullying
situations, and by providing the perpetrators with
the position of power and status in the long
run.
Bystanders Matter
How bystanders behave when witnessing bul-
lying is important from the perspective of the
individual children targeted by bullying, but also
from the perspective of the whole bullying dy-
namics of the classroom.
Research has demonstrated that the victims
who have classmates supporting and defending
them are better off than victims without defend-
ers. The defended victims are less depressed and
anxious, they have a higher self-esteem, and they
are less rejected by peers than victims without
defenders, even when the frequency of their
victimization experiences is taken into account
(in other words, their better adjustment is not
only a result of the fact that they are bullied
to a lesser extent; Sainio, Veenstra, Huitsing,
& Salmivalli, 2011). Furthermore, interviews of
adults who used to be bullied during their school
days (Teräsahjo, 1997) have revealed that the
most traumatic memories related to past bullying
are often related to the feeling that no one cared,
rather than to the attacks of the perpetrators as
such. Thus, even one bystander taking sides with
the victimized child or expressing support to him
or her can make a difference.
How bystanders respond when witnessing bul-
lying also influences the extent to which bullying
behavior takes place in a given classroom. Class-
rooms vary in how much and how often bullying
is taking place; about 7% of total variation in
bullying behavior is due to differences between
different classrooms (the rest being due to in-
dividual differences; see Salmivalli, Voeten, &
Poskiparta, 2011). Although the percentage may
seem relatively low, it means that there are some
characteristics of the classroom context (in addi-
tion to characteristics of individual children) that
explain why there is more bullying in some class-
rooms than in others. The classroom differences
can be partly explained by the degree to which
classmates tend to reinforce bullying versus sup-
port and defend victimized peers (Nocentini,
Menesini, & Salmivalli, 2013; Salmivalli et al.,
2011). More specifically, the more classmates
tend to reinforce bullies’ behavior and the less
they provide support to the victims, the more of-
ten bullying is likely to take place in a classroom.
Furthermore, some well-known individual risk
factors for victimization, such as social anxiety,
are more likely to lead to victimization in some
classrooms than in others: again, this depends
on whether it is common among classmates to
reinforce the bullies or support the victimized
peers (Kärnä, Voeten, Poskiparta, & Salmivalli,
2010). Even vulnerable at-risk children do not
necessarily end up as victimized, if the classroom
context does not support such behavior.
The important role of teachers in creating
an environment that does not support bullying
should be noted. Teachers’ efforts to intervene
in bullying, or lack of such efforts, may affect
classroom norms regarding bullying and related
behaviors. Students who perceive their teacher as
clearly disapproving of bullying are less likely
to engage in it (Saarento, Kärnä, Hodges, &
Salmivalli, 2013). Also, it has been found that
positive and supportive student–teacher relation-
ships increase students’ willingness to report
bullying (Eliot, Cornell, Gregory, & Fan, 2010).
Implications for Interventions
Targeting the Group: Why and How?
Children and adolescents facing bullying
problems as bystanders are in a controversial
situation. On one hand, they understand that
bullying is wrong and they would like to do
something to stop it—on the other hand, they
strive to secure their own status and safety in the
peer group. However, if fewer children took on
288

Salmivalli Participant Roles in Bullying
the role of reinforcer or assistant when witnessing
bullying, and if the group refused to assign high
status for those who bully, important rewards for
bullying would be lost. Although peers are often
part of the bullying problem, they can also be part
of the solution. Therefore, the success of bullying
prevention/intervention efforts often depends on
how well peer bystanders are utilized in such
efforts.
Bystanders are likely to be easier to influence
than the active, initiative-taking bullies. The by-
standers often think that bullying is wrong; they
feel bad for the victim, and they would like to
do something to help. Converting their already
existing attitudes into behavior is a challenging
task, but it might nevertheless be a more realistic
goal than influencing an individual bully by adult
sanctions or rewards only.
Even if the change in bystanders’ behavior
would not lead (at least immediately) to changes
in the bully’s behavior, it is very likely to make
a difference in the victim’s situation. Mobilizing
the peer group to support the victim is crucial
in minimizing the adverse effects for those who
are victimized. Victimization is an attack on the
victim’s status, but also on his or her need to
belong (Hawker & Boulton, 2001), and often a
successful one. Having protective friendships or
supporters in the classroom has been shown to
buffer against further victimization, as well as
the negative influences of victimization (Boulton,
Trueman, Chau, Whitehand, & Amatya, 1999;
Hodges, Boivin, Vitaro, & Bukowski, 1999;
Sainio et al., 2011).
Raising children’s awareness of the role by-
standers have in the bullying process is impor-
tant. Many children and youth may think that
as long as they do not participate in bullying
behavior as perpetrators, they do not have any-
thing to do with the problem. Introducing the
different participant roles to children and having
them reflect on their own typical behavior when
witnessing bullying may already be helpful (“I
don’t really approve of bullying and I would like
it to stop, but admittedly, I often laugh when Lisa
is making fun of Mary”). Students may even be
provided feedback about their typical participant
roles, as observed by the teacher or by class-
mates. Students can discuss together and brain-
storm ways in which they might change their re-
sponses to bullying into more constructive ones.
Enhancing children’s empathic understanding
of the victims’ situation can strengthen their
motivation to stand up for victimized peers. Short
films of former victims telling how bullying has
influenced their schooldays, but also their lives
later on, can be helpful. Also learning-by-doing
exercises where children have a chance to un-
derstand the feelings resulting from victimization
from the target’s standpoint provide them insight
into the negative feelings associated with such a
plight. Role-play can also be used to explore the
feelings associated with other participant roles.
How does it feel to witness bullying without
doing anything on behalf of the victim? Why is it
difficult to show disapproval of bullying or take
sides with the vulnerable peers?
Students should be provided with safe strate-
gies to support the victim. This does not nec-
essarily mean heroic acts such as intervening
in the bully’s behavior directly, but more subtle
ways in which the victimized peer can be made
feel included and supported. Also, when children
decide to express their disapproval of bullying
together as a group, they are likely to be safe—
and much more influential. After identifying
strategies of countering bullying as an individual
and as a group, these strategies can be rehearsed
in exercises done together in classrooms, or in
smaller groups. When the reward structure of
the classroom changes, supporting and defending
the victim can actually become reinforced and
rewarded.
Because of the group mechanisms involved in
bullying, the teacher is usually the key person in
delivering the preventive interventions described.
This is not to say that parents are unimportant;
however, the whole group (such as the students in
a classroom, smaller peer networks within class-
rooms) is present at school together as a group,
and the teacher has the possibility to interact with
this group, whereas the parents typically know—
and interact with—their own child and perhaps
some closest friends of their child. The school is,
therefore, a unique place to work with the group
and to influence its norms.

Theories of Bullying and Cyberbullying
Focusing on bystanders in bullying preven-
tion/intervention work does not mean that indi-
vidual bullies should not be targeted at all. When
bullying comes to the attention of adults, the
particular case should be handled, not together
in the classroom but by private, firm discussions
with the individuals involved. Even in such cases,
however, other peers (e.g., some prosocial class-
mates of the targeted child) can be met separately
and encouraged to think of ways in which they
could support the victimized peer who is having
a difficult time.
Can Bystanders Be Influenced by
Interventions?
The important role of bystanders in the bul-
lying process and, consequently, the potential
reductions in bullying that could be achieved by
influencing this group of children is not a new
idea; it has been discussed in the literature for
about 2 decades. It is more rare, however, to
find research where the idea has been put into an
empirical test, examining whether it is possible
to influence bystander behaviors by school-based
interventions (usually delivered by teachers), and
whether changes in bystander responses actually
lead to reductions in bullying.
Polanin, Espelage, and Pigott (2012) identi-
fied 12 studies evaluating the effects of school-
based programs that focused on increasing by-
stander intervention (e.g., Creating a Peaceful
School Learning Environment, Expect Respect,
Kiusaamista Vastaan [Against Bullying; KiVa]
antibullying program, Steps to Respect). Accord-
ing to their meta-analysis, the programs had
(on average) statistically significant effects on
bystander behaviors (intervening on behalf of the
victim), suggesting that it is, indeed, possible to
change peer responses to bullying. There was
variation between different programs, however,
and looking at their effects individually reveals
that six out of the 12 programs yielded significant
changes in the desired direction, that is, leading
to more bystander intervention. In most cases,
the effects were in the expected direction, even
if not significant.
Only one intervention study (Saarento, Boul-
ton, & Salmivalli, 2014) has tested whether
changes in bystander behaviors, in turn, lead to
reduced levels of bullying. The study was done
in the context of evaluating the effects of the
KiVa antibullying program (www.kivaprogram.
net; Salmivalli, Poskiparta, Ahtola, & Haataja,
2013) which is strongly built on the partici-
pant role approach to bullying. The universal
and indicated actions included in the KiVa pro-
gram (three different curricula of student lessons,
online antibullying games, school-based KiVa
teams tackling the cases of bullying coming to
attention together with classroom teachers) are
based on the principles of raising awareness
and empathy, and providing safe strategies to
intervene on behalf of the victimized peers rather
than rewarding the bullies.
It was found by Saarento and colleagues
(2014) that one mechanism through which KiVa
reduced bullying perpetration was by changing
students’ perceptions of how their classmates
responded to bullying as bystanders. In other
words, the KiVa program led individual children
to see more defending of victimized students
in their classroom environment, which in turn
reduced their own engagement in bullying perpe-
tration. Even though other mechanisms of KiVa
effects (e.g., changes in students’ attitudes, as
well as their perceptions of teachers) were found
as well, especially the results concerning how
perceptions of the peers’ reactions influenced
bullying perpetration lends support to the view
that bystanders are important for either maintain-
ing bullying or stopping it, and they should be
utilized in interventions.
