Recent years have seen a shift in bullying research from a dyadic focus on
the characteristics of the Bully and the Victim to the recognition of bully
ing as a whole group process, with the majority of children playing some ki
nd of role, This study uses a shortened adaptation of the Participant Role
Scale approach [Salmivalli et al. 1996, Aggr Behav 22:1-15] to identify the
se roles in 193 children aged 7 to 10 years. Four main factors were identif
ied, indicating that the adapted scale remains a reliable way of distinguis
hing the Victim, Defender of the victim, and Outsider roles both from each
other and from roles involved in bullying others. Progress in the measureme
nt of bullying as a group process and the success of intervention strategie
s may depend on finding clearer distinctions between ringleader Bullies and
the children that help them or reinforce their behavior, using the Partici
pant Role Scale approach to mobilize peer pressure and isolate ringleaders
from their social support. (C) 1999 Wiley-Liss, Inc.
