Revisiting the Use of Propensity Score Matching to Understand the Relationship between Gang Membership and Violent Victimization: A Cautionary Note

Abstract

Previous research has consistently reported that gang members are more likely to experience violent victimization compared to non‐gang members. Recently, however, a study challenged this conventional wisdom using the Gang Resistance Education and Training (GREAT) data. Employing propensity score matching (PSM), this study reported no significant differences in violent victimization between gang and non‐gang members. Upon closer examination of the GREAT data and the PSM process used in this study, we note several theoretical, methodological, and statistical concerns. We reanalyze the GREAT data using both negative binomial regression and PSM. We find that self‐reported gang members were significantly more likely to report subsequent violent victimization compared to non‐gang members. Although contrary to this previous study, our findings are consistent with the bulk of previous empirical research and widely held beliefs about the relationship between gang membership and violent victimization.
