Delinquent Behavior, Violence, and Gang Involvement in China

Objectives

This study examines the relationship between delinquent behavior and gang involvement in China. We assess the feasibility of self-report methodology in China and whether established findings in US and European settings on the relationship between gang involvement, violence specialization, and delinquent behavior extend to the Chinese context.

Methods

Data were gathered from 2,245 members of a school-based sample in Changzhi, a city of over 3 million people in Northern China. Drawing from a detailed survey questionnaire that measures prominent theoretical constructs, multi-level item response theory modeling was used to examine the association of gang involvement with general and specific forms of delinquency, notably violence specialization.

Results

Over half of the sample engaged in some form of delinquency over the prior year. Eleven percent of the sample reported gang involvement. Large bivariate differences in overall delinquency and violence specialization between gang and non-gang youth were observed. Multivariate analyses with measures of low self-control, household strains, family and school attachment, parental monitoring, and peer delinquency reduced the bivariate effect sizes, but current and former gang members had higher log odds of overall delinquency and violence specialization.

Conclusion

In helping fill gaps of knowledge on gangs and delinquency in the world’s most populous country, this study observed self-reported rates of delinquency and gang involvement not unlike Western countries. Findings on the relationship between gangs and delinquency, particularly violence, are consistent with the current literature and support the invariance hypothesis of gang involvement.     

Uncovering the Pathways Between Gang Membership and Violent Victimization

Objectives

Gang members are more likely to be victimized violently than non-gang youth, but the extent to which this relationship is confounded, direct, or mediated remains unclear. This study responds to recent calls by scholars for more methodologically sound research in this area with the goal of uncovering the pathways between gang membership and violent victimization.

Methods

Using a school-based longitudinal sample of adolescents, the current study uses Preacher and Hayes multiple mediator structural equation modeling and counterfactual methodology to test whether and which theoretical pathways—self-control, cultural orientations, routine activity, and lifestyle theory—mediate the contemporaneous and prospective effects of gang membership on violent victimization.

Results

The results indicate that 27 % of the contemporaneous effects of gang membership on victimization is attributable to selection, with the remaining 73 % endogenous to gang membership, supporting Thornberry et al.’s (J Res Crime Delinquency 30:55–87, 1993) enhancement model. Entry into a gang increases risk taking, temper, self-centeredness, negative peer commitment, neutralization of violence, aggressive conflict resolution, unstructured socializing, and delinquency, and decreases empathy and positive peer commitment. The contemporaneous gang membership-victimization link was fully mediated, due almost entirely to delinquency. Prospective models reveal a gang membership-victimization link that is fully confounded by selection, although attrition and desistance from gangs may be responsible for this finding.

Conclusions

The existing risky attitudes and behaviors of youth who select into gangs matters a great deal for understanding the gang membership-victimization link, but these very risks are exacerbated upon entry into a gang. Our mediation findings suggest that interventions targeting highly delinquent gang members should pay dual dividends of reducing delinquency and victimization.

     

Gangs and Violence: Disentangling the Impact of Gang Membership on the Level and Nature of Offending

Objectives

To determine whether membership in youth gangs provides a unique social forum for violence amplification. This study examines whether gang membership increases the odds of violent offending over and above involvement in general delinquent and criminal behavior.

Methods

Five waves of data from a multi-site (seven cities) panel study of over 3,700 youth originally nested within 31 schools are analyzed. We estimate four level repeated measures item response theory models, which include a parameter to differentiate the difference in the log of the expected event-rate for violent offense items to the log of the expected event-rate for nonviolent offense items.

Results

Depending on the comparison group (gang youth, overall sample), periods of active gang membership were associated with a 10 or 21% increase in the odds of involvement in violent incidents. When the sample is restricted to youth who report gang membership during the study, the proportionate increase in the odds of violence associated with gangs is statistically similar for males and females. After youth reported leaving the gang their propensity for violence was not significantly different than comparison group observations, although levels of general offending remain elevated.

Conclusions

While results are limited by the school-based sampling strategy, the importance of gang prevention and intervention programming for violence reduction is highlighted. Preventing youth from gang membership or shortening the length of gang careers through interventions may reduce absolute levels of violence.     

“From Your First Cigarette to Your Last Dyin’ Day”: The Patterning of Gang Membership in the Life-Course

Objective

Motivated by the reorientation of gang membership into a life-course framework and concerns about distinct populations of juvenile and adult gang members, this study draws from the criminal career paradigm to examine the contours of gang membership and their variability in the life-course.

Methods

Based on nine annual waves of national panel data from the NLSY97, this study uses growth curve and group-based trajectory modeling to examine the dynamic and cumulative prevalence of gang membership, variability in the pathways into and out of gangs, and the correlates of these pathways from ages 10 to 23.

Results

The cumulative prevalence of gang membership was 8 %, while the dynamic age-graded prevalence of gang membership peaked at 3 % at age 15. Six distinct trajectories accounted for variability in the patterning of gang membership, including an adult onset trajectory. Gang membership in adulthood was an even mix of adolescence carryover and adult initiation. The typical gang career lasts 2 years or less, although much longer for an appreciable subset of respondents. Gender and racial/ethnic disproportionalities in gang membership increase in magnitude over the life-course.

Conclusions

Gang membership is strongly age-graded. The results of this study support a developmental research agenda to unpack the theoretical and empirical causes and consequences of gang membership across stages of the life-course.     

Race and Gang Affiliation: An Examination of Multiple Marginality

Criminological research has historically drawn a connection between race/ethnicity and gang membership. The focus on specific racial/ethnic groups and particular gangs in distinct geographical locations within ethnographic research, along with the lack of a comprehensive explanation, however, has limited this research. Thus, the true nature of the relationship between race/ethnicity and gang membership remains unclear. This research expands the contemporary literature regarding race/ethnicity and gang membership by utilizing multisite survey data to examine Vigil’s (1988 Vigil, J. D. 1988. Barrio gangs: Street life and identity in southern California, Austin, TX: University of Texas Press.  [Google Scholar], 2002 Vigil, J. D. 2002. A rainbow of gangs: Street cultures in the mega‐city, Austin, TX: University of Texas Press.  [Google Scholar]) multiple marginality framework of gang involvement for Whites, African Americans, and Hispanics. Results suggest that multiple marginality is a viable explanation for current gang membership. When examining the applicability of this theory for members of various racial/ethnic groups, important differences appear when examining current versus ever gang membership. For current gang membership, significant differences between racial/ethnic groups exist, with ecological/economic stress variables being significant for Whites and social control/street socialization elements representing the important predictors for African Americans and Hispanics. This pattern changes when examining those reporting ever being in a gang. For “ever” gang membership, social control/street socialization elements predict membership for all groups. Policy implications of these results are discussed.     

Understanding the relationship between violent victimization and gang membership

Purpose

Research examining factors that precipitate gang violence has contributed substantially to our understanding of gangs and gang activity with respect to offending, yet we still know relatively little about how gangs influence members’ risk of victimization. The current study examines three hypotheses: (1) gang involvement and involvement in other risky lifestyles is related to violent victimization, (2) involvement in gang crime is associated with violent victimization, and (3) the presence of rival gangs is related to violent victimization.

Methods

The present study uses data obtained from 909 recently booked juvenile arrestees who were interviewed as part of the Arizona Arrestee Drug Abuse Monitoring (ADAM) program.

Results

Our findings indicated that prevalence of violent victimization was highest among gang members, followed by former gang members, gang associates, and non-gang members. After controlling for involvement in gang crime, however, gang membership per se did not significantly influence the juveniles’ risk of serious violent victimization.

Conclusions

Our results call into question the conclusion that gang membership alone increases the likelihood of violent victimization vis-à-vis lifestyle/routine activities and/or collective liability. Instead our findings support prior research on the victim-offender overlap, that offending behaviors increase the risk of victimization.     

Prison gang integration and inmate violence

Purpose

Gang membership has been linked in a number of prior studies with inmate misconduct; known gang members are more prone than non-gang members to act violently behind bars. Theories of intergroup conflict suggest, however, there is reason to expect that broader within-prison gang dynamics, not just gang membership alone, are associated with the incidence of violence.

Methods

We collected data on inmates from a large southern state and estimated multilevel models of inmate-on-inmate violence. Included in our models were a variety of common individual-level correlates of violent misconduct, among them gang membership. Substantive prison-level correlates included the percentage of gang members and “gang integration,” the latter being a measure of gang heterogeneity.

Results

We found a modest association between both gang variables and inmate-on-inmate violence, with gang integration being the most significant of the two.

Conclusions

Gang membership is an important correlate of inmate violence, but attention to broader prison gang dynamics is clearly necessary. We discuss the implications of this finding for theories of inmate violence.     

Partying,Cruising, and Hanging in the Streets: Gangs,Routine Activities,and Delinquency and Violence in Chicago, 1959–1962

Objectives

Examine relationships between routine activities, character contests in the form of “signifying,” and general delinquency and fighting in a street gang context.

Methods

Samejima’s (Estimation of latent ability using a response pattern of graded scores. Psychometrika monograph supplement 17. Psychometric Society, Richmond, VA, Retrieved 10 Aug 2011, from http://www.psychometrika.org/journal/online/MN17.pdf, 1969) graded response models and multilevel ordinal logistic regression models are estimated using data from Short and Strodtbeck (Group process and gang delinquency. University of Chicago Press, Chicago, 1965) study of street gangs in Chicago, 1959–1962. The primary sample consists of 490 boys representing 10 black gangs, 4 white gangs, 9 black lower-class groups, 4 white lower-class groups, 2 black middle-class groups, and 2 white middle-class groups.

Results

Unstructured and unsupervised socializing with peers significantly increased the likelihood of delinquency among the boys and explained a significant portion of the group-level gang effect. In addition, the more time the boys spent hanging in the streets and attending parties, the more likely they were to participate in signifying, which, in turn, increased their risk of fighting.

Conclusions

Findings provide evidence that gangs contribute to delinquency partly through their effect on the routine activities of members. Findings also suggest that signifying is an important mechanism by which unstructured and unsupervised socializing with peers leads to violence.     

Birds of a Feather Fight Together: Status-Enhancing Violence,Social Distance and the Emergence of Homogenous Gangs

Objectives

This study proposes a theoretical framework for understanding two empirical findings from gang research: (1) gangs are generally racially homogenous, even in heterogeneous environments, and (2) gang violence tends to be intra-racial. We draw from the extensive literature on street gangs as well as from research on group formation and status-enhancing behavior to develop a theoretical model of gang formation.

Methods

Using game theory, we model the simultaneous decisions of individuals to commit status-enhancing acts of violence and to seek protection by joining a gang. We then conduct computer simulations to examine the resulting patterns of violence and gang composition.

Results

We demonstrate that as long as some social distance exists between racial groups in a community, gang violence will be intra-racial and gangs will be homogenous. We find that our results are robust to a number of simple variations of the model and allow us to generate several hypotheses about the nature of gang formation and patterns of violence.

Conclusions

When violence is motivated by socially constructed rewards, socially closer targets are likely to yield greater rewards. In such a system, individuals must reduce their likelihood of victimization by entering a social contract of non-violence (i.e. gang membership) with individuals who might view them as status-enhancing targets (i.e. socially close individuals). The result is that gangs are made up of socially close individuals interested in attacking other socially close individuals. Therefore, gangs tend to be racially homogenous and violence is overwhelmingly intra-racial.

     

Lessons from a partially controlled field trial

Objectives

Using the case of an on-going work-oriented prisoner-reentry experiment in Milwaukee, describe the challenges of organizing and sustaining a high-quality trial in the field in which only the randomization and data analysis are directly ??controlled?? by the evaluation team.

Methods

The case study is of a randomized experiment involving youthful male prisoners with a history of violence and gang membership, scheduled for release into Milwaukee. The intervention included six months of pre-release services with a work-release opportunity, and intensive services and supervision following release. The case study describes the initial experimental plan and how much of that plan could be salvaged in the face of delays, administrative errors, and other problems.

Results

The initial plan, when compared with the actual experiment, specified a larger and more homogeneous sample, more resources devoted to various aspects of the treatment, and more intensive supervision following release. These problems arose despite the best efforts of public officials. Randomization was preserved, and for that reason the results will still be of interest, although perhaps under-powered.

Conclusions

The ??gold standard?? may become a bit tarnished in the field. It was crucial in this experiment to have a member of the experimental team engaged with the relevant state agencies at every step of the process to sustain this effort and to ensure that the treatment was delivered and relevant data generated. A newsletter and regular meetings with agents proved useful. The outcomes will have high internal validity.     

Groups, gangs, and delinquency: Does organization matter?

Purpose

A consistent finding of research on delinquency has been that gang members show higher levels of delinquent behavior than non-gang members. However, research attempting to understand the mechanisms underlying this finding is lacking. The basic premise of the current article is that the level of organization found in delinquent groups and gangs matters in clarifying the relationship between membership and delinquency.

Methods

This article examined the association between organization and delinquency in a sample of 523 self-reported juvenile offenders from a high school survey conducted in the province of Quebec, Canada.

Results

The results showed that 1) there is clearly something special about membership in a gang that influences delinquency beyond the more general membership in a delinquent group; 2) the key to understanding finding lies, in part, in the level of organization found in gangs. Organization emerged as the most important factor associated with general delinquency, involvement in violence, and in drug supply offences, significantly (but not completely) reducing the effect of gang membership on delinquency.

Conclusions

Even if most delinquent associations show little signs of formal structure and organization, this study demonstrates the importance of organization as a key mechanism to understand the gang effect on delinquency.     

The continued importance of measuring potentially harmful impacts of crime prevention programs: the academy of experimental criminology 2014 Joan McCord lecture

Objective

Joan McCord was a very influential criminologist and strong advocate for measuring potentially harmful effects in well-meaning crime prevention programs. This paper demonstrates the continued importance of measuring adverse program effects by reviewing the available research evidence on classic and contemporary gang streetworker programs.

Methods

This paper draws upon the evaluation findings of existing gang streetworker evaluations and presents the unpublished results of a rigorous quasi-experimental evaluation of a contemporary gang streetworker program that directly measured whether the intervention impacted the violent gun behaviors of treated gangs relative to untreated gangs.

Results

Evaluations of classic pre-1970s gang streetworker programs generally found that these interventions increased gang delinquency by reinforcing group identity and enhancing gang cohesion. Evaluations of contemporary gang streetworker programs are mixed, with several studies documenting concerning increases in gang violence. An unpublished evaluation found that the streetworker program was well-implemented and executed. However, the intervention was associated with increased shootings by and against treatment gangs relative to control gangs.

Conclusion

These findings suggest that contemporary gang streetworker programs are at high risk of generating unintended adverse outcomes for treated gang members relative to their untreated counterparts. Existing and planned programs should be monitored with a high degree of vigilance and evaluated with controlled evaluation designs.

     

Deterring Gang-Involved Gun Violence: Measuring the Impact of Boston’s Operation Ceasefire on Street Gang Behavior

Objectives

The relatively weak quasi-experimental evaluation design of the original Boston Operation Ceasefire left some uncertainty about the size of the program’s effect on Boston gang violence in the 1990s and did not provide any direct evidence that Boston gangs subjected to the Ceasefire intervention actually changed their offending behaviors. Given the policy influence of the Boston Ceasefire experience, a closer examination of the intervention’s direct effects on street gang violence is needed.

Methods

A more rigorous quasi-experimental evaluation of a reconstituted Boston Ceasefire program used propensity score matching techniques to develop matched treatment gangs and comparison gangs. Growth-curve regression models were then used to estimate the impact of Ceasefire on gun violence trends for the treatment gangs relative to comparisons gangs.

Results

This quasi-experimental evaluation revealed that total shootings involving Boston gangs subjected to the Operation Ceasefire treatment were reduced by a statistically-significant 31 % when compared to total shootings involving matched comparison Boston gangs. Supplementary analyses found that the timing of gun violence reductions for treatment gangs followed the application of the Ceasefire treatment.

Conclusions

This evaluation provides some much needed evidence on street gang behavioral change that was lacking in the original Ceasefire evaluation. A growing body of scientific evidence suggests that jurisdictions should adopt focused deterrence strategies to control street gang violence problems.     

Motives and methods for leaving the gang: Understanding the process of gang desistance

Purpose

This study examined the process of leaving the gang. Gang membership was conceptualized in a life course framework and the motives for why and methods for how one leaves the gang were analyzed.

Methods

Data were gathered from a sample of 84 juvenile arrestees in Arizona, all of whom left their gang. Motives for leaving the gang were organized into factors internal (push) and external (pull) to the gang, while methods for leaving the gang were organized into hostile and non-hostile modes of departure. Motives and methods were cross-classified and their correlates were examined, notably in relation to gang ties—persisting social and emotional attachments to the gang.

Results

Push motives and non-hostile methods were the modal responses for leaving the gang. While it was not uncommon to experience a hostile departure from the gang, most former gang members reported walking away without ritual violence or ceremony. This method was conditional on the motive for departure, however. None of the individuals leaving the gang for pull or external reasons experienced a hostile departure. While gang ties persisted regardless of motive or method, retaining such ties corresponded with serious consequences.

Conclusions

A life course framework is capable of organizing similarities between leaving the gang and desistance from other forms of crime and deviant groups. The process of gang desistance is consistent with asymmetrical causation. Due to limited attention to this process, a typology is introduced as a basis for understanding leaving the gang in relation to desisting from crime.     

Gang involvement and delinquency in a middle school population

The relationship between self-reported gang involvement and self-reported delinquency has been confirmed in a number of studies. However, there have been fewer studies of the relationship between self-reported gang involvement and officially recorded delinquency. This article examines variation in self-reported gang involvement, operationalized as three distinct categories—no involvement, gang involvement but not membership, and gang membership—and its relation to both self-reported and officially recorded delinquency for a population of middle school youths.     

The causal relationship between gang joining and violent victimization: A critical review and directions for future research

Purpose

This article provides a critical review of the state of research on the gang membership-violent victimization relationship.

Methods

This study examines a comprehensive list of published quantitative studies that have assessed the relationship between gang membership and violent victimization.

Results

By examining strengths and weaknesses of the design features of various studies, this article identifies theoretical, conceptual, methodological, and statistical issues that should be considered when interpreting the causal effect of gang membership on violent victimization. Some of the methodological and design issues discussed include, but are not limited to, consequences of failing to establish temporal order, failure to conduct sensitivity analyses to determine treatment effects, use of bootstrapping methods with propensity score analysis, measurement of violent victimization, and corrections for dependence in matched samples of gang and non-gang members.

Conclusion

Suggestions for future research are provided that will help advance the empirical study of the gang membership-violent victimization nexus.     

The effect of prison gang membership on recidivism

Purpose

How does prison gang membership affect recidivism? In this paper, we use a unique dataset of all releasees from prisons operated by the Illinois Department of Corrections during the month of November 2000, which includes demographic information and data on gang participation. We attempt to control for confounding factors that are traditionally associated with both prison gang membership and rearrest.

Methods

We develop a potential-outcomes framework and describe the conditions under which a counterfactual can be estimated when gang membership is not randomly assigned. We combine regression analysis with Coarsened Exact Matching, which has several advantages over the more popular propensity score matching, to estimate the effect of gang membership on recidivism.

Results

Prison gang membership results in a six percentage point increase in recidivism.

Conclusions

Despite the strengths of the data, unobserved heterogeneity among inmates could still bias estimates. However, there are probably important subtleties to the gang participation decision such that experimental or quasi-experimental data are unlikely to increase our understanding of the relationship between gang-membership and post-release outcomes. We recommend incorporating ethnography with survey data collection, because ethnographers are able to document otherwise unobservable contextual information concerning the selection process which could be used to identify causal relationships.     

When Criminal Coping is Likely: An Examination of Conditioning Effects in General Strain Theory

Objectives

This paper addresses a central problem in general strain theory (GST): the mixed results regarding those factors said to condition the effect of strains on crime. We test Agnew’s (Deviant Behav 34(8):653–670, 2013) assertion that a criminal response to strain is likely only when individuals score high on several factors that increase the propensity for criminal coping or possess markers that indicate a strong propensity for criminal coping.

Methods

We use survey data from nearly 6000 juveniles from across the United States to examine whether the effect of criminogenic strains across several domains—perceptions of police, school environment, and victimization—on crime are conditioned by: (1) respondents’ criminal propensity and (2) gang membership. To the best of our knowledge, this is the first criminological study to employ an analytical framework that simultaneously considers nonlinear (i.e., curvilinear) dynamics, non-additive (i.e., interactive) effects, and non-normally distributed dependent variables. This approach has the advantage of properly differentiating nonlinear and non-additive dimensions and therefore significantly improving our understanding of conditioning effects.

Results

We find considerable support for Agnew’s (2013) postulation about conditioning effects and GST. Criminal behavior is more likely among those with a strong overall propensity for criminal coping and among gang members. Furthermore, we discover that the conditioning effects are, themselves, nonlinear. That is, the effect of criminal propensity on moderating the relationship between our three measures of strain and delinquency varies across the range of the criminal propensity index. Our models that simultaneously consider both the non-additive and nonlinear relationship between strains, criminal propensity, and criminal offending better fit the data than models that consider these dimensions separately. These results hold whether examining a composite measure of criminal activity or, alternatively, three separate subscales indexing violent, property, and drug offenses.

Conclusion

Our study advances GST and the crime literature by identifying the types of strained individuals most likely to engage in criminal coping. Additionally, the analytical framework we adopt serves as a model for the correct measurement and interpretation of conditioning effects for criminological data, which almost invariably violate the assumptions of the linear regression model. Parametric interactions are the most commonly investigated type of interactions, but other kinds of interactions are also plausible and may reveal conditional relationships that are either overlooked or understated when analysts adopt a fully parametric framework. We demonstrate the utility of expressly modeling both the nonlinear effects of component variables in an interaction and the nonlinear nature of the conditioning effect.

     

Gang Membership,Drug Selling,and Violence in Neighborhood Context

A prominent perspective in the gang literature suggests that gang member involvement in drug selling does not necessarily increase violent behavior. In addition it is unclear from previous research whether neighborhood disadvantage strengthens that relationship. We address these issues by testing hypotheses regarding the confluence of neighborhood disadvantage, gang membership, drug selling, and violent behavior. A three‐level hierarchical model is estimated from the first five waves of the 1997 National Longitudinal Survey of Youth, matched with block‐group characteristics from the 2000 U.S. Census. Results indicate that (1) gang members who sell drugs are significantly more violent than gang members that don’t sell drugs and drug sellers that don’t belong to gangs; (2) drug sellers that don’t belong to gangs and gang members who don’t sell drugs engage in comparable levels of violence; and (3) an increase in neighborhood disadvantaged intensifies the effect of gang membership on violence, especially among gang members that sell drugs.
