Peer Conflict Scale (PCS)
The Peer Conflict Scale (PCS) is a copyright protected 40-item questionnaire designed to assess aggressive behavior in children and adolescents. The scale has items assessing Physical Proactive Aggression, Physical Reactive Aggression, Relational Proactive Aggression and Relational Reactive Aggression. There are three versions of the scale: Peer Conflict Scale – Parent Version, Peer Conflict Scale – Teacher Version, and Peer Conflict Scale-Youth Version. Researchers can download and use the PCS free of charge in their work. The only requirement is that the instructions, item wording, and item response format not be changed.
There is no manual for the PCS. Several studies which describe the development of the scale, its subscale structure, and initial tests of its validity can be obtained here.
