“…This measure was developed over 35 years ago and is still in use today with no diminution in its relevance for children of varying ethnicity, race, socioeconomic status, or geographical location around the world (Guerra, Huesmann, Tolan, Van Acker, & Eron, 1994;Huesmann & Eron, 1986;Pulkkinen, 1987). Its concurrent validity has been demonstrated in both laboratory (Williams, Meyerson, Eron, & Semler, 1967) and field studies (Eron et al, 1971); its construct validity has been demonstrated in the many theoretically predicted relations into which it enters (e.g., Eron, Laulicht, Walder, Farber, & Spiegel, 1961); and its predictive validity has been demonstrated over 3 years (Huesmann & Eron, 1986), 11 years (Lefkowitz, Eron, Walder, & Huesmann, 1977), and 22 years, as seen in its relation to the occurrence of aggression, violence, delinquency, and criminal behavior over those periods (Huesmann et al, 1984). A number of similar peer-nomination scales have been derived and are also in widespread use in aggression research (Bjorkqvist, Lagerspetz, & Kaukiainen, 1992;Dodge & Coie, 1987;Perry, Perry, & Rasmussen, 1986;Wiggins & Winder, 1961).…”
