A revised version of The Peer Experiences Questionnaire (RPEQ; Prinstein, et al. 2001) was used to assess participants’ engagement in aggression toward peers. The RPEQ included 18 items that assess aggression toward peers. Participants rate how often they engage in a specific behavior toward others in the past year (e.g., “I threatened to hurt or beat up another kid”) on a 5-point Likert scale ranging from never (1) to a few times a week (5). The RPEQ has also demonstrated good internal consistency on both versions of the measure (aggressor and victim), as well as for the subscales, and convergent validity (Prinstein et al. 2001). The RPEQ demonstrated good internal consistency in this sample (α=0.90).
