This study is made to determine the predictive powers of the perceived social support, parental attitude, school success, school change and living in different area of residences variables in the students of 8th grade who are exposed to peer-victimization. The data of the research has been procured from 550 students who are eighth-graders in Diyarbakir and Kocaeli. The data related to the predicted variable has been collected by using Peer-victimization Scale (Mynard & Joseph, 2000) and the data related to the predictor variables has been gathered by using the Perceived Social Support Scale -- Revised Form (Yildirim, 2004), the Parental Attitude Scale (Lamborn, Mounts, Steinberg & Dornbush, 1991) and the Personal Information Form prepared by the researcher. The statistical analysis of the gathered data has been performed in computer by using SPSS 11.5 packaged software. Multiple Regression Analysis is used in determining the variables predicting peer-victimization exposure which is the purpose of the study. On the other hand, the Stepwise Regression Analysis is implemented in order to determine the explanatory variables having high correlation coefficient and the predicted variable. The findings obtained by the research can be summarized as the following: School success, perceived social support and authoritarian parental attitude are the variables predicting the peer-victimization exposure. It has been found out that the other variables in the analysis do not predict the exposure of the students to the peer-victimization. The findings obtained in the research are discussed and commented and suggestions have been made based on the facts.
