Reconsidering the "gang effect" in the face of intermittency: Do first- and second-time gang membership both matter?

Research demonstrates that joining a gang is associated with amplified criminal behavior. Given that gang membership can be a transient and intermittent status, we question whether it has a consistent effect on offending regardless of whether an individual joins a gang for the first time or rejoins (for the second time). Using panel data from the Rochester Youth Development Study ( = 1,217 person-periods nested within 177 individuals), we employ a within-persons analysis via multilevel structural equation models with fixed slopes.

Peer influence and context: the interdependence of friendship groups, schoolmates and network density in predicting substance use.

This article focuses on the degree to which friends' influence on substance use is conditioned by the consistency between their behavior and that of schoolmates (individuals enrolled in the same school, but not identified as friends), contributing to the literature on the complexity of interactive social influences during adolescence. Specifically, it hypothesizes that friends' influence will diminish as their norms become less similar to that of schoolmates. The authors also propose that this conditioning relationship is related to the density of the friendship group.

Maternal cigarette smoking during pregnancy and criminal/deviant behavior: a meta-analysis.

A growing body of empirical literature has emerged examining the somewhat inconsistent relationship between maternal cigarette smoking (MCS) during pregnancy and children's subsequent antisocial behavior. To systematically assess what existing studies reveal regarding MCS as a criminogenic risk factor for offspring, the authors subjected this body of literature to a meta-analysis. The analysis reveals a statistically significant--yet rather small--overall mean "effect size" of the relationship between MCS and the likelihood children will engage in deviant/criminal behavior.

Cognitive ability and delinquent behavior among inner-city youth: a life-course analysis of main, mediating, and interaction effects.

Drawing on the emerging life-course paradigm in criminological theory, this study examines the relationship between cognitive ability and delinquent behavior within a sample of inner-city youth. The results indicate that net of statistical controls, cognitive ability maintains a robust inverse relationship with the likelihood of the onset of delinquency, the early onset of delinquency, and the persistence of delinquency during the 18-year period covered by the dataset. Furthermore, cognitive ability mediates the effect of concentrated disadvantage on both the onset and early onset of delinquency.
