Examining the Genetic Underpinnings to Moffitt's Developmental Taxonomy: A Behavioral Genetic Analysis
J.C. Barnes, Kevin M. Beaver and Brian B. Boutwell
In recent years, criminological research has observed an increase in studies examining different offending trajectories. Much of this research has been guided by Moffitt's (1993) developmental taxonomy of life-course persistent offenders, adolescence-limited offenders, and abstainers. Moffitt (1993) argued that the etiologies of these different pathways could be traced to several biosocial factors, including perhaps genetic factors. To date, research has failed to address this possibility directly. The current study addressed this gap in the literature by examining the extent to which genetic factors explain variance in different offending patterns. Analysis of sibling pairs (N = 2,284; ages spanned between 11 and 27 years) drawn from the National Longitudinal Study of Adolescent Health (Add Health) revealed that genetic factors contributed significantly to being classified in each of the different offending patterns. Specifically, genetic factors explained between 56 and 70 percent of the variance in being classified as a life-course persistent offender across different coding strategies, 35 percent of the variance in being classified as an adolescence-limited offender, and 56 percent of the variance in being classified as an abstainer. We discuss the importance of integrating genetics into future studies examining offending trajectories.
Ghettos, Thresholds, and Crime: Does Concentrated Poverty Really Have an Accelerating Increasing Effect on Crime?
John R. Hipp and Daniel K. Yates
Theories make varying predictions regarding the functional form of the relationship between neighborhood poverty and crime rates, ranging from a diminishing positive effect, to a linear positive effect, to an exponentially increasing or even threshold effect. Nonetheless, surprisingly little empirical evidence exists testing this functional form. This study estimates the functional form of the relationship between poverty and various types of serious crime in a sample of census tracts for 25 cities, and it finds that a diminishing positive effect most appropriately characterizes this relationship whether estimating the models nonparametrically or parametrically. Only for the crime of murder does some evidence exist of an accelerating effect, although this occurs in the range of 20 to 40 percent in poverty, with a leveling effect on crime beyond this point of very high poverty. Thus, no evidence is found here in support of the postulate of scholars extending William Julius Wilson's (1987) insight that neighborhoods with very high levels of poverty will experience an exponentially higher rate of crime compared with other neighborhoods.
The Cascading Effects of Adolescent Gang Involvement across the Life Course
Marvin D. Krohn, Jeffrey T. Ward, Terence P. Thornberry, Alan J. Lizotte and Rebekah Chu
The short-run deleterious effects of gang involvement during adolescence have been well researched. However, surprisingly little empirical attention has been devoted to understanding how gang involvement in adolescence influences life chances and criminal behavior in adulthood. Drawing on the life-course perspective, this study argues that gang involvement will lead to precocious transitions that, in turn, will have adverse consequences on the fulfillment of adulthood roles and statuses in the economic and family spheres. Moreover, problems fulfilling these conventional roles are hypothesized then to lead to sustained involvement in criminal behavior in adulthood. Using data from a sample of males from the Rochester Youth Development Study, results from structural equation models support the indirect link between gang membership and noncriminal and criminal outcomes in adulthood. Specifically, gang involvement leads to an increase in the number of precocious transitions experienced that result in both economic hardship and family problems in adulthood. These failures in the economic and family realms, in turn, contribute to involvement in street crime and/or arrest in adulthood. Implications for the criminal desistance process are discussed.
On Ambiguity in Perceptions of Risk: Implications for Criminal Decision Making and Deterrence
Thomas A. Loughran, Raymond Paternoster, Alex R. Piquero and Greg Pogarsky
Deterrence theorists and researchers have argued that the critical dimension of sanction certainty is its level—increasing the certainty of punishment from a lower to a higher level will inhibit criminal conduct. However, the true certainty of punishment is rarely known with much precision. Both Sherman (1990) and Nagin (1998) have suggested that ambiguity about the level of punishment certainty is itself consequential in the decision to commit or refrain from crime. Here, we investigate this proposition. We find some evidence that individuals are “ambiguity averse” for decisions involving losses such as criminal punishments. This finding means that a more ambiguous perceived certainty of punishment is a greater deterrent of some crimes than a nominally equivalent but less ambiguous one. However, this effect depends on how large an individual's risk certainty perception is initially. That is, we find evidence for “boundary effects” (Casey and Scholz, 1991a, 1991b) in which this effect holds for lower probabilities but reverses for higher ones. For higher detection probabilities, individuals become “ambiguity seeking” such that a less ambiguous detection probability has more deterrent value than a nominally equivalent but more ambiguous detection probability. Results are presented from two distinct, but complementary, analysis samples and empirical approaches. These samples include a survey to college students with several hypothetical choice problems and data from the Pathways to Desistance study, a longitudinal investigation of serious adolescent offenders transitioning from adolescence to young adulthood.
Neuropsychological Measures of Executive Function and Antisocial Behavior: A Meta-Analysis
James M. Ogilvie, Anna L. Stewart, Raymond C. K. Chan and David H. K. Shum
A meta-analysis was performed to quantify the association between antisocial behavior (ASB) and performance on neuropsychological executive functioning (EF) measures. This meta-analysis built on Morgan and Lilienfeld's (2000) meta-analysis of the same topic by including recently published studies and by examining a wider range of EF measures. A total of 126 studies involving 14,786 participants were included in the analyses. Antisocial groups performed significantly worse on measures of EF compared with controls, with a grand mean effect size of d= .44. Significant variation occurred in the magnitude of effect sizes calculated across studies. The largest effect sizes were found for criminality (d= .61) and externalizing behavior disorder (d= .54) ASB groups, whereas the smallest effect sizes were found for antisocial personality disorder (d= .19) groups. Larger differences in EF performance were observed across studies involving participants from correctional settings and with comorbid attention deficit and hyperactivity problems. Overall, the results indicated that a robust association exists between ASB and poor EF that held across studies with varied methodological approaches. The methodological issues in the research literature and the implications of the meta-analysis results are discussed, and the directions for future research are proposed.
Associations of Fathers' History of Incarceration with Sons' Delinquency and Arrest Among Black, White, and Hispanic Males in the United States
Michael E. Roettger and Raymond R. Swisher
Nearly 13 percent of young adult men report that their biological father has served time in jail or prison; yet surprisingly little research has examined how a father's incarceration is associated with delinquency and arrest in the contemporary United States. Using a national panel of Black, White, and Hispanic males, this study examines whether experiencing paternal incarceration is associated with increased delinquency in adolescence and young adulthood. We find a positive association with paternal incarceration that is robust to controls for several structural, familial, and adolescent characteristics. Relative to males not experiencing a father's incarceration, our results show that those experiencing a father's incarceration have an increased propensity for delinquency that persists into young adulthood. Using a national probability sample, we also find that a father's incarceration is highly and significantly associated with an increased risk of incurring an adult arrest before 25 years of age. These observed associations are similar across groups of Black, White, and Hispanic males. Taken as a whole, our findings suggest benefits from public policies that focus on male youth “at risk” as a result of having an incarcerated father.
Does the Time Cause the Crime? An Examination of the Relationship Between Time Served and Reoffending in the Netherlands
G. Matthew Snodgrass, Arjan A. J. Blokland, Amelia Haviland, Paul Nieuwbeerta and Daniel S. Nagin
This work uses a sample of Dutch offenders, serving an average of 6.7 months of confinement, to examine the relationship between time served in prison and future criminality. To overcome the selection issues inherent in this examination, this article introduces a new method to the criminological literature that relies on a generalization of the propensity score to control for observed differences in offenders sentenced to different periods of confinement. On the whole, very little evidence of a relationship between time served and future offending was found. In particular, 3-year reconviction rate and the proportion of offenders reconvicted in the next 3 years do not seem to depend on incarceration length. Although a relationship between time served and future sentence length was found, the evidence is modest.
The Effects of Employment on Longitudinal Trajectories of Offending: A Follow-Up of High-Risk Youth from 18 to 32 Years of Age
Victor R. Van Der Geest, Catrien C. J. H. Bijleveld and Arjan A. J. Blokland
This article analyzes the effects of employment on delinquent development from 18 to 32 years of age in 270 high-risk males. Prior to 18 years of age, all men had undergone residential treatment for serious problem behavior in a juvenile justice institution in the Netherlands. We use semiparametric group-based models to investigate the effect of employment on their offending, taking into account static personality and background characteristics. We examine the effect of being employed and further distinguish the effects of job quality (“on the payroll” or being employed through temporary work agencies) and job stability (duration). We find that employment is significantly related to delinquent development among most (active) offender groups. Among high-frequency chronic offenders, only temporary employment is significantly associated with a reduction in offending, whereas among high-frequency desisters, the association is significantly stronger with regular employment. Stability in employment was limited in our sample, and it did not have an additional effect on offending.
Decomposing the Peer Effect on Adolescent Substance Use: Mediation, Nonlinearity, and Differential Nonlinearity
Gregory M. Zimmerman and Bob Edward Vásquez
Although the correlation between peer delinquency and delinquency is one of the most consistently demonstrated findings in delinquency research, researchers have focused primarily on the direct, linear, and additive effects of peers in statistical models, rather than on empirically modeling mediating, nonlinear, and moderating processes that are specified by theory. To address these issues, we measure respondent delinquency and peer delinquency with illegal substance use and then decompose the effect of peer substance use on self-reported substance use. Logistic hierarchical models on a sample of adolescents from the Project on Human Development in Chicago Neighborhoods (PHDCN) indicate that the effect of peer substance use on self-reported substance use is partially mediated by perceptions of the health risks of substance use. In addition, the direct statistical effect of peers is nonlinear: On average, the peer effect decreases at higher values of peer substance use, which is consistent with a “saturation” effect. We also find that the functional form of the peer substance use/substance use relationship is dependent on the neighborhood context. In neighborhoods with more opportunities for crime, the peer effect is initially strong but decreases as peer substance use increases, which is consistent with a saturation effect. Conversely, in neighborhoods with fewer opportunities for crime, the effect of peers is initially small, but as delinquent peer associations increase, the peer effect increases multiplicatively.
