Among the measures assessing peer reputation, the Extended Class Play (ECP) is now used extensively in North American settings. Little information is available in other cultural contexts. Furthermore, practical considerations suggest developing a shorter form of the ECP to be used in socio-educational environments. This study examined the ECP dimensions of peer assessment in Italy as well as developed a shorter form of the measure. We revised the ECP using factor analyses according to an explorative-confirmatory approach. The original 37-item ECP was shortened to a 22-item version and, subsequently, the properties of the revised measure were evaluated. We performed two studies comprising, respectively, 643 (55% male; 97% Italian; Mage = 12.20, SD = 0.60) and 652 (58% male; 94% Italian; Mage = 12.26, SD = 0.66) seventh-grade young adolescents living in southern and central Italy. Results revealed a clear and consistent seven-factor structure and acceptable levels of reliability and validity. Factors included constructs such as Shyness-Withdrawal, Prosociality-Leadership, Aggression, Popularity-Sociability, Victimization, Rejection-Exclusion, and Boastfulness. Correlations between the dimensions of the 22-item ECP and teacher ratings of young adolescents' behaviors further confirmed the validity of the solution. Findings suggest the importance of culturally revised measures of social reputation and indicate that the short form of the ECP has considerable promise to be considered a valuable measure to assess the multidimensional aspects of peer relationships.
