The study aims to determine how the variables of peer deviance, gender, grade level, having too many problems, parental divorce, and guidance by the school counselor about delinquency contribute to predicting delinquency levels in adolescents. The research was conducted upon 277 adolescents (high school students)."The Delinquency Scale", "The Peer Deviance Scale", and a "Personal Information Form" were used to obtain data. The collected data were analyzed by multiple regression analysis. The research revealed that the variables of peer deviance, gender, grade level, having too many problems, and parental divorce are significant predictors of adolescent delinquency, while guidance by the school psychological counselor about delinquency does not constitute a significant predictor.
