Peer Conflict Scale

 

The Checkmate Plus Peer Conflict Scale (Gadow, 1986) contains 10 items that assess interpersonal peer aggression and are based on the physical and nonphysical aggression categories from the Checkmate Plus ADHD School Observation Code (ADHD-SOC). In the ADHD-SOC the term physical aggression refers to negative physical contact against another person using a body part (e.g., hitting, biting, kicking, tripping, pushing) or an implement (e.g., striking another child with an object) AND the aggressee responds either neutrally or negatively (e.g., strikes back, grimaces, complains).The term nonphysical aggression refers to three subcategories of aggressive behavior:  verbal aggression, symbolic aggression, and object aggression.  Verbal and symbolic aggression are interpersonal, but the aggressor does not make physical contact with the aggressee.  These include verbalizations and physical gestures that are abusive or threatening and directed toward other people.  These two subcategories encompass all negative, noncontact communication.  They also include stealing or taking the possessions of another person when the possessions are not on the victim's (aggressee's) body.  Object aggression is aggressive behavior directed toward objects in the child's environment (e.g., the observed child inflicts physical damage on an object by hitting, throwing, and so forth).  If the object is thrown at another person, this is considered physical aggression.

 

The Peer Conflict Scale appears in the following Checkmate Plus Symptom Inventories:

 

  • Early Childhood Inventory (preschool)

  • Child and Adolescent Symptom Inventory (elementary & secondary school)

  • ADHD-Symptom Checklist (children and adolescents)

 

The Peer Conflict Scale of Checkmate Plus Symptom Inventories is one of the most well-documented measures of peer aggression and is reported on in numerous scientific publications, representative examples of which are Daniels, Volpe, Briesch, and Gadow, 2017; Gadow, 1986; Gadow, Arnold, Molina, et al., 2014; Gadow, Brown, Arnold, et al., 2016; Gadow and Nolan, 1993, 2002; Gadow, Nolan, Sverd, J., et al., 1990; Giacobo, Jane, Bonillo, et al., 2012; Nolan and Gadow, 1994; and Volpe and Gadow, 2010.
