This article analyzes data from a survey research study of students in the fifth through twelfth grades of an upper middle class Chicago suburban community. The findings indicate the use of alcohol and drugs among both prepubertal and teenage students, and the involvement of both groups in theft and vandalism. The level of community affluence and quality of community institutions and services rule out the explanations (“the tangle of pathology”) usually offered in studies of delinquency in lower class and low-income communities. Peer group pressures and psychogenic factors appear to influence these kinds of acting-out behavior. And since considerable numbers of students noted that their parents had not established certain important regulations for them, the view advanced by this study is that deficient socialization and inadequate parenting also appear to be causes of these behavioral problems. However, since the study did not categorize the data in a way to permit cross-tabulations either supporting or invalidating this argument, this conclusion is a tentative one. It is suggested that future research dealing with these problems among this social stratum investigate the influence of parenting on acting-out behavior.
