In this paper we will discuss our unsuccessful attempt to conduct a self-report study of delinquent behavior in an urban multi-racial high school in Portland, Oregon. Much of this report reflects our preparation in conducting a self-report study and our analysis of why if failed. The contention of this study is that delinquent behavior, and not juvenile delinquency is the major problem facing youth serving agencies and the public. The purpose of this study is an attempt to refine an often used method of measuring delinquent behavior – the self–report. Favoring a self–report technique of data collection rather than an analysis of rate variations, a comparison of matched samples or a study of subcultures, tends to ground this study in a “radical non-intervention” approach to the field of delinquent behavior. This particular approach views delinquent behavior as widespread throughout society rather than concentrated among the economically disadvantaged or in a certain subculture of the adolescent population.
