Bullying Participant Behaviors Questionnaire (BPBQ): Establishing a Reliable and Valid Measure

The current study further establishes the reliability and validity of the Bullying Participant Behaviors Questionnaire (BPBQ), a self-report survey that allows for an examination of participation in various bullying participant role behaviors including bully, assistant to the bully, victim, defender of the victim, and outsider. The study included 801 sixth- through eighth-grade students. The results of the study confirmed a five-factor structure (Bully, Assistant, Victim, Defender, and Outsider). Internal consistency of the subscales was high and item-subscale correlations were all significant and moderate to high. Correlations among the BPBQ subscales and with additional measures, including the Behavior Assessment System for Children, Second Edition, Self-Report of Personality (Reynolds & Kamphaus, 2004), the Social Skills Rating System (Gresham & Elliott, 1990), and an unpublished victim measure (Demaray & Malecki, 2003), provided evidence of concordant, convergent, and divergent validity. Gender and grade level differences were also investigated among the bullying participant behaviors.
