Marsee Aggression & Delinquency Lab

The Peer Conflict Scale (PCS) measures proactive physical aggression, proactive relational aggression, reactive physical aggression, and reactive relational aggression over 40 items. The PCS is copyright protected, and its three versions are free to download for researchers to use in their work:  Peer Conflict Scale – Parent Version, Peer Conflict Scale – Teacher Version, and Peer Conflict Scale-Youth Version. If used for research purposes,  the instructions, item wording, and response format must remain unchanged. The PCS does not include a manual. However, articles that discuss the scale development and its use can be found here.
