Early prevention of life-course personal and property violence: a 19-year follow-up of the Montreal Longitudinal-Experimental Study (MLES)

Objectives

This study assessed the impact of a multi-component prevention program on personal and property violence across three developmental periods (early adolescence, mid-adolescence and late adolescence/early adulthood).

Methods

The preventive intervention targeted disruptive kindergarten boys from low socioeconomic status families when they were 7 through 9 years of age. A randomized control trial was conducted to assess the impact of the preventive intervention relative to a control group.

Results

Two different approaches to data analysis were adopted: an intention-to-treat (ITT) approach and an instrumental variable (IV) approach. Results from the ITT analysis showed that the level of property violence for the intervention group was persistently lower across the three developmental periods compared to the control group. However, the intervention group did not differ from the control group on personal violence throughout adolescence and early adulthood. Results from the IV analysis generally confirmed these findings.

Conclusions

The discussion focuses on the differential effects of the prevention program on personal versus property violence.     

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.     

A Bi-level Framework for Understanding Prisoner Victimization

Objectives

To present and test an opportunity perspective on prison inmate victimization.

Methods

Stratified random samples of inmates (n ₁ = 5,640) were selected from Ohio and Kentucky prisons (n ₂ = 46). Bi-level models of the prevalence of assaults and thefts were estimated. Predictors included indicators of inmate routines/guardianship, target antagonism, and target vulnerability at the individual level, and several indicators of guardianship at the facility level.

Results

Assaults were more common among inmates with certain routines and characteristics that might have increased their odds of being victimized (e.g., less time spent in recreation; committed violence themselves during incarceration), and higher levels of assaults characterized environments with lower levels of guardianship (e.g., architectural designs with more “blind spots”, larger populations, and less rigorous rule enforcement as perceived by correctional officers). Similar findings emerged for thefts in addition to stronger individual level effects in prisons with weaker guardianship (e.g., ethnic group differences in the risk of theft were greater in facilities with larger populations and less rigorous rule enforcement).

Conclusions

The study produced evidence favoring a bi-level opportunity perspective of inmate victimization, with some unique differences in the relevance of particular concepts between prison and non-prison contexts.     

The next generation of court-mandated domestic violence treatment: a comparison study of batterer intervention and restorative justice programs

Objectives

The most common approach to treatment of domestic violence crimes in the United States is the mandated group-based Batterer Intervention Program (BIP). Several alternative treatment approaches have been developed over the years, including a restorative justice-based treatment program for domestic violence offenders called Circles of Peace (CP). This study compared a CP program administered in Arizona with a local BIP program, in controlled settings.

Methods

This study involved a randomized controlled trial with 152 domestic violence cases randomly assigned to either BIP or CP between September 2005 and March 2007. Independent sample t tests were used to measure treatment outcomes post-random assignment, in terms of both domestic violence and non-domestic violence re-arrest rates during four follow-up periods (6, 12, 18, and 24 months).

Results

CP participants experienced less recidivism than BIP during all follow-up comparisons. However, statistically significant differences were detected only for the 6-month (p?<?.1) and the 12-month (p?<?.05) follow-up comparisons for non-domestic violence re-arrests, and no statistically significant differences were detected for the domestic violence re-arrests.

Conclusions

The findings are generally statistically non-significant at .05. While these results do not suggest a change in policy from BIP to CP for domestic violence crimes, it does dispel the popular belief that restorative justice cannot be used to treat domestic violence criminal activity, in that CP does no worse than the traditional batterer intervention program. Given the low statistical power and high attrition rates, more research is necessary to test CP and restorative justice treatment generally in court-mandated domestic violence cases in order to understand the treatment impact on both domestic violence and non-domestic violence offenders.     

An experimental trial of adaptive programming in drug court: outcomes at 6, 12 and 18 months

Objectives

To test whether an adaptive program improves outcomes in drug court by adjusting the schedule of court hearings and clinical case-management sessions pursuant to a priori performance criteria.

Methods

Consenting participants in a misdemeanor drug court were randomly assigned to the adaptive program (n?=?62) or to a baseline-matching condition (n?=?63) in which they attended court hearings based on the results of a criminal risk assessment. Outcome measures were re-arrest rates at 18 months post-entry to the drug court, and urine drug test results and structured interview results at 6 and 12 months post-entry.

Results

Although previously published analyses revealed significantly fewer positive drug tests for participants in the adaptive condition during the first 18 weeks of drug court, current analyses indicate the effects converged during the ensuing year. Between-group differences in new arrest rates, urine drug test results and self-reported psychosocial problems were small and non-statistically significant at 6, 12, and 18 months post-entry. A non-significant trend (p?=?.10) suggests there may have been a small residual impact (Cramer’s v?=?.15) on new misdemeanor arrests after 18 months.

Conclusions

Adaptive programming shows promise for enhancing short-term outcomes in drug courts; however, additional efforts are needed to extend the effects beyond the first 4 to 6 months of enrollment.     

“Can’t Stop,Won’t Stop”: Self-Control,Risky Lifestyles,and Repeat Victimization

Objectives

Drawing from lifestyle-routine activity and self-control perspectives, the causal mechanisms responsible for repeat victimization are explored. Specifically, the present study investigates: (1) the extent to which self-control influences the changes victims make to their risky lifestyles following victimization, and (2) whether the failure to make such changes predicts repeat victimization.

Methods

Two waves of panel data from the Gang Resistance Education and Training program are used (N = 1,370) and direct measures of change to various risky lifestyles are included. Two-stage maximum likelihood models are estimated to explore the effects of self-control and changes in risky lifestyles on repeat victimization for a subsample of victims (n = 521).

Results

Self-control significantly influences whether victims make changes to their risky lifestyles post-victimization, and these changes in risky lifestyles determine whether victims are repeatedly victimized. These changes in risky lifestyles are also found to fully mediate the effects of self-control on repeat victimization.

Conclusions

Findings suggest that future research should continue to measure directly the intervening mechanisms between self-control and negative life outcomes, and to conceptualize lifestyles-routine activities as dynamic processes.     

Seasonal Variation in Violent Victimization: Opportunity and the Annual Rhythm of the School Calendar

Objectives

This study draws on an underused source of data on seasonality—victim surveys—to assess whether violent crime occurs with greater frequency during summer months or whether it simply becomes known to police more often, and to examine the extent to which seasonal patterns in violent crime are differentiated based on victim characteristics and location of crime.

Methods

Data used come from the 1993–2008 National Crime Victimization Survey. Time series regression models are estimated to describe seasonal differences in violent crime victimization and reporting rates.

Results

Seasonal trends in youth violence stand in contrast to the trends for young and older adults, primarily due to their high risk of victimization at and near school. No evidence of seasonality is found in the extent to which serious violence becomes known to the police. However, simple assault is significantly more likely to come to the attention of the police during the summer months, primarily due to increases in the reporting of youth violence.

Conclusions

Our findings confirm some of the previous work on seasonal patterns in violent crime, but also show that these patterns vary across age groups, locations, and type of violence.     

Supervision mode effects in computerized delinquency surveys at school: Finnish replication of a Swiss experiment

Objectives

This study provides a Finnish replication of a recent Swiss experiment (Walser and Killias: J Exp Criminol 8:17–28, 2012) on the supervision mode effects in computerized delinquency surveys in schools. This study supplements the Swiss study by using individual level randomization and two additional outcome variables: meta-questions of response integrity and incidence-counting heuristics.

Methods

A total of 924 ninth grade students (15–16 years old) in southern Finland were randomly assigned (at the level of individuals) to supervision either by their teachers or by an external research assistant. Students then responded to an online self-report delinquency survey. Chi-square and t tests were used to compare prevalence levels and means.

Results

In both last year and lifetime recall periods, only one offence type (unspecified theft) showed significantly different outcomes, with external supervision yielding a higher prevalence figure. For other offences, no supervision effects were found. When females and males were separately examined, limited evidence of gender-specific supervision effects emerged. Thus, females appear to report more thefts in external supervision while males report more violence in teacher supervision. No statistically significant supervision effects were found in questions probing response integrity and counting heuristics.

Conclusion

Using teacher supervision in online self-report delinquency surveys does not appear to compromise the validity of the survey results. The findings thus largely corroborate the results of the earlier Swiss test. How supervision condition interacts with respondent characteristics apart from gender calls for further scrutiny.     

The “care package,” prison domestic violence programs and recidivism: a quasi-experimental study

Objectives

Although there are many evaluations of domestic violence rehabilitation programs, it is still unclear “what works” in this field, especially when it comes to programs within prison walls. Today, most studies indicate that domestic violence programs based on cognitive behavioral treatment, or psycho-educational models show small positive results. Yet, there is still insufficient empirical literature providing adequate evidence for the impact of integrative treatment, where different methods and approaches toward domestic violence prisoners are employed within the same rehabilitation-program framework while incarcerated. Our study examined the effects of an integrative domestic violence program with a therapeutic “package” implemented in Israel with the goal of reducing recidivism rates among prisoners in general, and especially with regard to violent offenses.

Methods

Using propensity score matching methods, we compared treated offenders to a matched sample drawn from all convicted prisoners who were released from prison between 2004 and 2012.

Results

The findings indicate that the percentages of reincarceration and rearrests of inmates, who participated in integrative domestic violence program, were significantly lower during a period of up to 4 years after release.

Conclusions

Our conclusion is that the integrative effect of different treatments along with a supportive prison climate increased the success of inmates who participated in the domestic violence program.

     

The Andrews’ principles of risk, needs, and responsivity as applied in drug treatment programs: meta-analysis of crime and drug use outcomes

Objectives

The purpose of the present meta-analysis was to answer the question: Can the Andrews principles of risk, needs, and responsivity, originally developed for programs that treat offenders, be extended to programs that treat drug abusers?

Methods

Drawing from a dataset that included 243 independent comparisons, we conducted random-effects meta-regression and ANOVA-analog meta-analyses to test the Andrews principles by averaging crime and drug use outcomes over a diverse set of programs for drug abuse problems.

Results

For crime outcomes, in the meta-regressions, the point estimates for each of the principles were substantial, consistent with previous studies of the Andrews principles. There was also a substantial point estimate for programs exhibiting a greater number of the principles. However, almost all the 95 % confidence intervals included the zero point. For drug use outcomes, in the meta-regressions, the point estimates for each of the principles was approximately zero; however, the point estimate for programs exhibiting a greater number of the principles was somewhat positive. All the estimates for the drug use principles had confidence intervals that included the zero point.

Conclusions

This study supports previous findings from primary research studies targeting the Andrews principles that those principles are effective in reducing crime outcomes, here in meta-analytic research focused on drug treatment programs. By contrast, programs that follow the principles appear to have very little effect on drug use outcomes. Primary research studies that experimentally test the Andrews principles in drug treatment programs are recommended.     

Counterterrorism and Radical Eco-Groups: A Context for Exploring the Series Hazard Model

Objective

This study examines whether radical eco-groups have been deterred by legal sanctions. From a rational choice framework, I argue that members of these groups weigh costs and benefits. I measure an increase in costs, or an objective deterrence effect, through four federal sentencing acts targeted at reducing the criminal behavior of these groups [the tree-spiking clause of the Anti-Drug Abuse Act (ADA), the Animal Enterprise Protection Act (AEPA), the Anti-Terrorism and Effective Death Penalty Act (AEDPA), and the Animal Enterprise Terrorism Act (AETA)] and hypothesize that this legislation decreased the hazard of subsequent attacks.

Methods

This research is a quasi-experimental design utilizing the 1,068 illegal incidents perpetrated in the name of the environment, animal, or both as extracted from the Eco-Incidents Database. Using series hazard modeling, I examine the time until the next incident, serious incident, and ideologically specific incident in relation to dummy variables operationalizing the enactment dates of the above legislation.

Results

All in all, the results are somewhat consistent with a rational choice framework and my hypotheses. The ADA decreased the hazard of another attack (11 %) and environment-only attack (15 %), while at the same time increasing the hazard of a terrorist, damage, and animal-related attack. AETA decreased the hazard of all (47 %), damage (42 %), and the behavior it was aimed at, that of animal-only incidents (52 %). However, neither the AEPA, nor AEDPA had a significant effect on any of the outcomes.

Conclusions

Overall, radical eco-groups were deterred by legal sanctions, but these findings are legislation and outcome specific in addition to including displacement effects.     

“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.     

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.     

Examining the effects of the TASER on cognitive functioning: findings from a pilot study with police recruits

Objectives

Despite its widespread adoption by more than two-thirds of police departments in the US, there has not been a single study examining the effects of the TASER on cognitive functioning. This inquiry is important for two reasons. First, research has consistently documented cognitive deficits following exposure to electricity (the TASER is an electrical device). Second, questions have emerged regarding whether TASER exposure impairs suspects’ ability to understand and waive their Miranda rights.

Methods

To explore this issue, the authors carried out a pilot study with 21 police recruits who received a TASER exposure as part of their training at the San Bernardino County (CA) Training Center. Each recruit was given a battery of cognitive tests 3–4 h before TASER exposure, within 5 min after exposure, and again 24 h after exposure.

Results

Recruits experienced statistically significant reductions in several measures of cognitive functioning following TASER exposure. However, all recruits had returned to their baseline levels of functioning within 24 h. Learning effects were documented in several of the cognitive tests.

Conclusions

The questions driving this study involve serious issues including constitutionally protected rights of the accused, use of force by police, and previously unexamined effects of the TASER on the human body. The pilot study represents a critical first step in exploring the effects of the TASER on cognitive functioning. Moreover, the results provided the authors with important information that will guide their larger study, a randomized controlled trial where healthy human volunteers will be randomly assigned to four groups, two of which receive a TASER exposure.     

‘Don’t Blow Your Cool’: Provocation,Violent Coping,and the Conditioning Effects of Self-Control

Objectives

General Strain Theory (Agnew in Criminology 30:47–87, 1992) has received broad empirical support, but little is known about moderators of the strain-delinquency relationship. This study tests whether self-control attenuates the relationship between a certain type of delinquency—violence—and its most important precursor, considered a type of strain: interpersonal provocation. This study compares the conditioning effects of risk-affinity and self-control/impulsivity on the provocation-violence link, since recent work suggests differentiating between both characteristics.

Methods

The provocation-violence link is examined (1) using a scenario design with randomly varied degrees of objective provocation and a measure of projected violence, and (2) with measures of self-reported past violence and subjective sensitivity to provocation. The analyses are based on a large sample of seventh-graders (n = 2635) from five cities in Western Germany, interviewed in 2013. Linear probability models regressing violence measures on personal traits, provocation measures, and their interactions are estimated.

Results

Both self-control and risk-affinity moderate the relationship between subjective sensitivity to provocation and past violent behavior. Students with high self-control are able to control their anger and do not turn violent, even when they feel provoked easily. However, only risk-affinity significantly amplifies the effect of objective provocation on prospective violence when simultaneously controlling for the conditioning effect of self-control.

Conclusions

Findings underscore that both self-control and risk-aversion are important coping resources. This study highlights the importance of using internally consistent and mechanism-congruent measures in the study of illicit coping processes and conditioning factors and discourages from using composite, potentially multidimensional measures.

     

How long did it last? A 10-year reconviction follow-up study of high intensity training for young offenders

Objectives

Most research has suggested that correctional boot camps are not very successful in reducing reoffending, but recent evidence has been more encouraging for programs that include significant rehabilitative components. In line with this, High Intensity Training (HIT) for offenders aged 18–21 at Thorn Cross Young Offender Institution in England was followed by a significant reduction in the number of reconvictions in a 2-year follow up. This article aims to evaluate the impact of the HIT program after 10 years.

Methods

The evaluation used a quasi-experimental design in which male young offenders who received HIT were individually matched, on their risk of reconviction, to a comparison group who went to other prisons. Official reconviction data, including the prevalence, frequency, types, and costs of offenses were used as the outcome measures.

Results

Offenders who received HIT had a significantly lower prevalence and frequency of reconvictions, but their superiority over the control group reduced over time (after about 4 years). However, the cumulative number of convictions that were saved increased steadily over time, from 1.35 per offender at 2 years to 3.35 per offender at 10 years. The cumulative cost savings also increased over time, and the benefit:cost ratio, based on fewer convictions, increased from 1.13 at 2 years to 3.93 at 10 years.

Conclusions

The beneficial effects of the HIT program became more obvious over time. More randomized experiments and long-term follow-up research, including regular interviews, are needed to evaluate the cumulative and persisting effects of correctional interventions more accurately.     

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.     

Risky Facilities: Crime Radiators or Crime Absorbers? A Comparison of Internal and External Levels of Theft

Objectives

To undertake the first exploration of the nature of the relationship between internal crime (those that happen within facilities) and external crime (those occurring outside but in the nearby locale of facilities). The following questions are addressed. Do those localities that suffer high volumes of crime internally within their facilities also suffer high levels of crime in their immediate external environment? How is this influenced by the distribution of internal theft across facilities? What are the likely mechanisms for any relationship found?

Methods

Spatial regression is used to explore these relationships using data for 30,144 incidents of theft from a Metropolitan area of the UK arranged into small 50 × 50 m grid squares. Variables used in the analysis include counts of external and internal theft, counts of victimized and ‘risky’ facilities, indicators of land-use and a proxy for the on-street population.

Results

There is found to be a strong positive relationship between internal and external theft that appears to be strengthened by the existence of facilities suffering particularly high crime volumes. Results suggest that internal theft problems precede external ones and that the physical concentration of chronically risky facilities is a particularly strong predictor of external theft problems.

Conclusions

An argument is made that risky facilities act as crime ‘radiators’, causing crime in the immediate environment as well as internally. This has implications for crime prevention policy in terms of facility placement and management.     

Accounting for Projection Bias in Models of Delinquent Peer Influence: The Utility and Limits of Latent Variable Approaches

Objectives

Projection effects have been shown to bias respondent perceptions of peer delinquency, but network data required to measure peer delinquency directly are unavailable in most existing datasets. Some researchers have therefore attempted to adjust perceived peer behavior measures for bias via latent variable modeling techniques. The present study tested whether such adjustments render perceived peer coefficients equal to direct peer coefficients, using original data collected from 538 young adults (269 dyads).

Methods

After first replicating projection effects in our own data and examining the degree to which measures of personal, perceived peer, and direct peer violence represent empirically distinct constructs, we compared coefficients derived from two alternative models of personal violence. The first model included an error-adjusted latent measure of perceived peer violence as a predictor, whereas the second substituted a latent measure of directly-assessed, peer-reported violence.

Results

Results suggest that personal, perceived peer, and direct peer measures each reflect fundamentally separate constructs, but call into question whether latent variable techniques used by prior researchers to correct for respondent bias are capable of rendering perceived peer coefficients equal to direct peer coefficients.

Conclusions

Research cannot bypass the collection of direct peer delinquency measures via latent variable modeling adjustments to perceived peer measures, nor should models of deviance view perceived peer and direct peer measures as alternative measures of the same underlying construct. Rather, theories of peer influence should elaborate and test models that simultaneously include both peer measures and, further, should attempt to identify those factors that account for currently unexplained variance in perceptions of peer behavior.
