The time-window effect in the measurement of repeat victimization: a methodology for its examination, and an empirical study

Abstract

Abstract: Crime control strategies and criminological theory have been increasingly informed by developments in the study of repeat victimization in recent years. As a consequence, the measurement of repeat victimization is an important issue. The outcome of the measurement of repeat victimization can influence the manner in which police and other agencies develop, implement and evaluate crime control efforts. In addition, the results of measurement can influence the theories and explanations that derive from empirical study. Among the several measurement issues that have been identified to date in relation to repeat victimization, a key issue is that of the "time-window effect. " The term refers to the fact that the length of the period of observation directly affects the proportion of repeat victimization that is "captured. " The present study has two key aims. First, it presents a method to measure the size of the time-window effect. Second, it tests this method em-Crime Prevention Studies, volume 13, pp. 15-27.Graham Farrell. William H.
