Peer victimization is a frequent occurrence for many adolescents; however, some of the psychometric properties of self-report scales assessing these experiences remain unclear.Furthermore, with an increase in access to technology, electronic aggression should also be considered. The study examined the psychometric properties of the Multidimensional Peer Victimization Scale (MPVS, Mynard & Joseph, 2000), and developed versions to include the assessment of electronic aggression according to whether the adolescent was the target or perpetrator of peer victimization. Three hundred and 71 (191 girls and 180 boys Mage = 13 years 4 months, SDage= 1 year 2 months) adolescents in the UK completed the MPVS including 5 newly developed items assessing electronic aggression, a version of the MPVS designed to assess victimization perpetration, and a measure of self-esteem. Confirmatory factor analyses yielded a five-factor structure comprising: Physical, social manipulation, verbal, attacks on property, and electronic for both scales. Convergent validity was established through negative associations between the victimization scales and self-esteem.Sex differences also emerged. One revised scale and one new scale are subsequently proposed: The Multidimensional Peer Victimization Scale -Revised (MPVS-R) and the Multidimensional Peer Bullying Scale (MPVS-RB).
