Selection and Facilitation: Is the Gang Membership-Psychopathic Traits Link a Product of Individual Differences,Social Influences,or Both?

Abstract

Objectives

The issue of psychopathology among gang populations is controversial. Classic gang scholarship points to psychopathic traits as time-stable characteristics of those who join gangs, others argue gangs facilitate attitudes and behaviors endogenous to psychopathy, stisll others reject a gang-psychopathic traits link. Building off an interdisciplinary theoretical basis that adapts a tripartite theoretical model (i.e., selection, facilitation, and enhancement) on the gang membership-offending link to the mixed positions on the gang membership-psychopathic traits relationship, this study tests selection and facilitation models.

Methods

Using longitudinal data from Pathways to Desistance, I examine whether psychopathic traits are an antecedent and/or consequence of gang membership. Specifically, I test whether (a) there are between individual differences in psychopathic traits that contribute to selection into gangs and (b) gangs facilitate within-individual change in psychopathic traits among their members.

Results

The findings suggest that the enhancement model (i.e., both selection and facilitation) best represents the relationship between gang membership and psychopathic traits.

Conclusions

Analyzing the role of individual propensities—like psychopathic traits—and social-environmental influences—like gang membership—is critical for understanding crime and criminality. This study demonstrates that these factors do not operate in isolation but instead interact bidirectionally. By moving beyond the selection-facilitation dichotomy, this study contributes to a more integrated framework for explaining problem behaviors and helps establish best practices for prevention and rehabilitation.
